GI: Turbo Kit

[jdm monkey]

Like the title says, just gaging interest in a VX bolt-on turbo kit. Price will be around $2,500 approx. for the complete kit good for +50-100 hp (on a stock engine).

[etlsport]

id probably be interested once it was proven... id still rather get ahold of a supercharger though

[kpaske]

Are the Alpine kits no longer available? They cost just a little bit more and have already been tested and proven.

[Joe_Black]

I'm sure the interest is there but among those that are you're going to need to provide a lot more details, such as how it's going to be plumbed.

[justatwinturbo]

details details details. what turbos will you use? will it be single or dual? i was thinking about trying a custom made turbo kit with the 2 wrx 13T turbos i have with 19T wheels......for the best bang for the buck, you cant beat dual 13Ts on a 3.5 liter. i'd be interested, the price is good but it needs to look nice, not something that looks like i could have made it in my garage

[CoastieCosta567]

Well they do still sell the supercharger, just in another website. here it is. I would buy it if they did payments not all at once.

[Thmstec]

If there is one thing I like more than superchargers, its turbo chargers! Work on the details, you've gotten my attention

[Chopper]

Better figure on a tranny upgrade to go with it. 50-100hp boost will grenade the stock one.

[So-CalVX]

I know that the supercharger is out of my rpm range... I rarely get over 3K. Where does the power come in on the turbo?

Can u do both??? :D

yah you can have a supercharger and a turbo charger... its called twin charged.

[jdm monkey]

what gives? the torque converter?
how much hp do supercharged vx have and all of them have tranny problems?

[Chopper]

The 5psi blower makes LESS than 50hp..... Mr. Apollo or one of the S/C'd guys will straighten me out...but the real number is more like 25 or 30. The Aisin unit in Axioms will take 300, but alas, the humble 4L30E will begin to shred around 265 or so. It was used in modestly powered things, like 3 series an such. It'll last a lot longer at 215hp. than 250.

[jdm monkey]

I can probably set the psi to a modest level and call it a stage 1 kit to keep the trans from grenading... I think what kills the trans is the increase in torque... I have the same issue in my Lexus SC400 I'm about to turbocharge; its auto tranny was never designed to handle 400hp but its stock 1uzfe engine will.

[etlsport]

i think the max torque rating for the 4l30e is 285, but yea like u said chopper, the more power you put to it the less life it will have

[Solitude]

Is that an accurate page?

[jdm monkey]

The initial plan for Stage 1 kit will use single T3/T4 mid mounted turbo that will replace the stock muffler and will use an oil pump for oil return, 38mm wategate boosting 5-7psi, BOV, FMU, Aluminum charge pipes, Stainless steel braided oil lines, boost gauge etc.

[WormGod]

I'm with Chopper on this. You may want to plan on stockpiling some trannys as well.

Plus, before I did too much thought work, I would at least take some close looks at the Mooncraft. That plumbing was pretty damned serious and actually called for a custom made front cladding to house the FMIC. There is no way you are gonna get a TMIC in there unless you go hoodless, heh.

In the end, S/C is the best choice with it's modest power and ease. ya ya, I know, not an easy thing to find, but, occasionally, one will pop up.

Good luck. Can't say it has never been brought up before.

(psst.... I actually prefer turbo myself. :bwgr: )

[Ldub]

And before you stockpile trannys, maybe get a VX ???:smilewink

You'll find pics of the mooncraft in my gallery.

[jdm monkey]

I have a VX I just got it a few months ago and yeah it would have been stupid to design a turbo kit for a vehicle you dont have. :) I've seen the mooncraft turbo kit and I didnt like the design.

My bad I guess...maybe update your profile.
From where I sit, it still says "none".

[jdm monkey]

ok, updated.

[Petos]

Is that an accurate page?

Good question - as far as I know - it is not... :(

BTW, I would be in the market for the turbo kit (as well as for the charger..)

[jdm monkey]

Prototype kit construction will start this spring. I'll keep you guys updated.

[Hotsauce]

Rear mounted turbo?

So, you're going to be running water and oil lins back and forth, and charge air forwards under the floorpan?

Thats going to be a HUGE volume of intake and exhaust to pressurise to get boost up. You're going to need a bypass valve for sure.

I've seen it done on other cars, but its always been a kludge.

Nice work....

[bigkoala1]

keep us updated

[WormGod]

Interesting in seeing how you plan out the cooling. MOAFMIC (mother of all front mount intercoolers)!!!! I have done front and top mount kits, but NEVER have I had to fab my own plumbing. I do not envy your task, heh.

Curious, what turbo are you considering and are you looking at, at least, a 3" turboback?

Keep it up.

[jdm monkey]

For 5-7psi low boost intercooling is not really needed and with the use of a relatively large compressor compressed air wont be as hot, also turbo placement is away from the engine bay, there's plenty of cold dense air at the turbo's current location. And yes, single 3" turbo back for the exhaust.
Ok now for more pics....

[WormGod]

I think the stock front cladding has a good capability for using a smaller FMIC. Since it has to be fabbed from scratch anyways, it is possible to get it closer to the chassis than the Mooncraft did. Looks like quite some space in there.... probably to keep it away from any radiator heat, but shouldnt be an issue if JDM's isnt putting out enough compression and only a small dose of cooling takes place with the FMIC anyways. Hell, even something small like the top mounts on the STi might suffice in that location without butchering the front end, heh.

So the wheel well was the best you could manage for plumbing? Hmm, shame. But hell, good to see you got this far along so far.

[Joe_Black]

Thanks for the pics, but YIKE! One, I'd like to be able to turn left again and two, have you calculated the pressure drop on that Rube Goldberg plumbing layout? Did you even consider simply fabbing new manifolds before neutering the roadability of the vehicle? :rolleyes:

[jdm monkey]

There is no clearance issue on the piping under the wheel well so yah, you can still turn left lol...

[Ascinder]

With what size wheels? Most people run larger tires. And is there any option to run that pipe somewhere other than where we would be mounting rocksliders? I know aluminum tubing doesn't take kindly to close encounters with the ground. Not trying to bust your chops, but if I were in your place, I would welcome constructive criticism, so.....:bgwo:

It's there! Now my tires are spinnin', 'stead of grabbing. This setup is gonna have some lag in it. Climbing rocks begs a S/C methinks.

[Ascinder]

Exhaust cutouts=best of both worlds methinks

[Chopper]

Think?? I've no experience:o Only negatives with turbos in muck

[Joe_Black]

Generally I agree that turbos aren't very well suited for off-road gasoline applications, but what we've been kicking around for my rally VX is to use two T-14 or T-23 turbos sitting on top of either tubular or log-type manifolds. Simple, robust short tube runs with everything accessible and high to eliminate heat or dousing issues. More than likely I'll end up with a 4JG2 diesel in it, but that's down the road until the big shop is done. :bgwo:

With what is proposed here you'll either set something on fire from radiant heating or the cast-iron section of the turbo will crack from constantly being drenched or packed in mud, especially if you try to implement heat shields in an area that's a "catch-all" underneath the chassis. What's your plan for addressing vibration on what looks about 20' of tube? When it's all said and done you'll need the extra horsepower to offset the added weight. ;)

[spitfire5454]

this is a very cool project. i had planned on doing this last year, but after all the bugs were worked out, i the supercharger was just easier. i used to have all sorts of data on set ups like this. ill see if i can dig some up. this is pretty much the only way to do it - i just dont see the room under the hood for a traditional turbo and manifold. STS systems are turbos like this and they seem to work fine. there will be a little lag, but it wont be a deal. also, the long charge pipe running under the car acts as a little intercooler as well. i love turbos, but you cant beat the mean looks of roots:)

[WormGod]

Right'o. Turbo for tarmac. S/C for insta-grab (that be dirt to ya'll city folk.... like me :D ).

Still, as a city to rural/suburban city transplant now, T/C and S/C appeal. Thus, the Rex and the Vex, heh.

I still think you are gonna wanna take a look into the pressure cause that setup really does concern me when it comes to lag. And without a proper tune (REALLY good luck on that one), I fear you wont see a bit of gain. But please, prove me wrong and make it work. I love an ongoing project. :cool:

[Hotsauce]

Part of the issue with doing a proper turbo setup(turbo just after header) is getting it emission certified.

The setup he's trying to build is more like a cat back exhaust.

I'm curious what the ECU will think when the BOV opens and metered air reverses through the MAS. I'm thinking that it will read as additional air intake, and dump in fuel for it as you lift the throttle.

With the BOV spring set stiff enough to remain closed at idle you may get some surges.

I do give props for trying though.

Ya, a good performance tune should be able to keep it from running ultra rich, but.... that's the question right there isnt it? Tune a VX? I remember years ago we had a member who programmed access ports for GM or something and he was gonna try to get around to putting together an access port for us to harness up to the ECU. I never did hear the end of that. :(

I took my VX to my WRX guys here in town to see what they thought about a post S/C tune and after 10 mins, they just threw their arms up and said "sorry dude". Damn shame cause I thought that if anyone could find a way, it would be them since they are one of the most renowned mid atlantic import tuner shops.

[reptiles]

Wow, this is fascinating. More power would be great on these vehicles.

Although the large FMIC looks good, I might prefer a smaller side mount (in the front of the wheel well.) Or maybe cool the pressurized charge with an Aquamist water/methanol injection pump?

Like someone said elsewhere in this thread; water or mud hitting a red-hot turbo housing is never a good thing. Even a titanium housing couldn't take much of the thermal shock of that.

I'm thinking that this project will get expensive (much more than $2,500) because of other upgrades... like a bigger brass radiator, electronic boost control (with AI fuzzy logic), new MAS, bigger fuel pump, injectors, air/fuel control, and associated stuff.

[jdm monkey]

Just a quick update... everthing is installed. I'm just waiting for my wideband sensor installed before driving. Sorry I had no time to take pics of vid. But I will as soon as everything is good to go.

[jdm monkey]

I'm dishing out the whole remote mount turbo thing... I'm not happy with the lag , the use of electric oil pump and the intake placement (under the car... bad for an off road vehicle). I'm going to redo the whole turbo system and place the turbo under the hood where it belongs! :)

[jdm monkey]

pics of new setup soon...

[So-CalVX]

I'm not gonna claim to know anything about setting up a turbo system but I am gonna ask a question... Why not do it Impreza style and mount the inter cooler under the hood insert and cut a hole under a scooped insert? Would that work? I'm asking this without opening my hood to see if there's any room there so I hope I don't sound stupid

No room for an IC under our hood. It would have to be one hell of a tiny one, and I mean TINY. Even if one did fit, I dont think the aero of our hood design is proper for the right cooling induction so we would probably need one hell of a high scoop (thinking no smaller than the '04-'05 STI scoop).

Front mount would work, granted you could design a new front clip like the Mooncraft, heh.

Definitely one of those mods/tasks I am glad to see someone else try out and not me, heh. :cool:

[zachary.berrier]

Please send me pics, i can help with your layout if you want. Im very knowledgeable about forced induction, turbos especially have built dsm's and currently have a 500hp wrx. i can help u with getting it under the hood. a front mount isnt that big of a deal. to locate the turbo you will need to fab an uppipe off the collector of equal lengths from the manifold. after that its simple. what size turbo are u using, and another thing the stock td04 is super small that people are talking about lag.The max flow is 475cfm at 18psi, with a 3.5l motor it shouldnt be a problem pushing it. A 2.0l spools it under 2k rpm. what size injectors are stock in the vehicross , also people commenting about the bov springs. Thats why jdm used an hks ssqv bov its a pull type that works off vaccum so its closed at idle and reacts fast and if people are really worried u can plumb it back into the intake before the turbo. ideal is lower compression to run higher boost, but with tuning and a catless 3 in. exhaust there will be power. good luck with the build and im looking to pick up a vehicross as a fun project now. Dont mean to thread jack, just figured i can help you if you need it in any regards with the subaru turbo system.

[Lizardmen3477]

I am deff in for this I am only in Md I will drive down there to have this done sounds great.

[jdm monkey]

Sorry guys I got side tracked a bit...
We are currently on a swap (k20 rsx engine in a toyota mr2 spyder + turbo) and a NSX turbo.Hopefully when the project is complete, i can give my 100% attention to the VX. Its just a matter of time... its going to happen. Sit back and relax.

[Griffin]

I heard about this MR2 setup, I wanna see this turboed VX more though. Get that thing running and we can test it. :D

I have a nice tow strap. Turbo's do work underwater right? lol

[xman]

dude that would be an amazing accomplishment for th vx... atleast until alpine decideds if they are doing the S/C stage 1 upgrade. even then i still think youll get more power from a turbo... besides they sound bad anus!

My engine is leaking coolant in the spark plug hole. Its either a bad head gasket or a cracked cylinder head. Gotta fix this first. Everything has been sorted out but i cant boost it yet.

[SouthJ1]

what happened to the turbo JDM i actually am looking into this

[yellowgizmo99]

I think he had engine problems.

[jdm monkey]

yeah first coolant was getting into the spark plug hole. Now, it may have spun a rod bearing. I'm currently rebuilding it and also mating a 5 speed and turbo. :)

[vt_maverick]

Before or after the Datsun in the garage? ;)

[SouthJ1]

I hope before

[jdm monkey]

Most likely before the datsun. :)

[jdm monkey]

Im also planning a piggy back engine management fir proper fuel/ignition mapping.

[vt_maverick]

You know with all the threads/posts on here about LS1 swaps, superchargers, etc., I would bet you could make GOOD money if you could get a turbo kit together before Alpine gets their *** in gear.

Btw, are you doing this as a single or dual turbo?

[jdm monkey]

Single Turbo.
I also have plans for a better superchager kit. I will be based on Rotrex supercharger. Less parasitic loss with good boost response (almost like a turbo), simple to install (no need to take the plenum out). No more old and heavy roots type supercharger. I just need a volunteer. :)

[vt_maverick]

Is that similar to the Vortec superchargers for the 350Z and G35? Idea is that it goes beside the engine rather than on top right?

And what constitutes being a "volunteer?" :naughty:

[jdm monkey]

Yeah similar set up. Get the goods and I'll fab brackets and piping. Its easy.

[tjh]

yeah first coolant was getting into the spark plug hole.

How does the coolant get into the spark plug hole?

[jdm monkey]

I suspect cracked head. I replaced both heads.

[SouthJ1]

jdm how much would it cost to set a vx up with the supercharger kit your talking about?

[jdm monkey]

There's no fixed price yet but it should go for around $3.5K

Update:
Done with the piggy back fuel controller for the VX!!! I'm trying to make a plug and play solution right now with no ECU wire splicing.

[SouthJ1]

3.5k isnt bad... im liking the sound of that lol

[Lizardmen3477]

Sooo if i come visit ya for a weekend can we get it done : D

Well, I was poking around on the web (nah, I don't crawl.... haha) and gues what I found in the North-Western Island called "Australia"?

You guessed it - A SUPERCHARGER KIT

(see below)
The quoted power (185kW / = 250Hp) is based on the lesser 6VD1 from the Trooper, factory rated at 142kW = 190Hp)
That's a 60Hp increase, meaning that your 6VE1 would max out at about 270-ish HP or 200kW for us metricans.
Damn - that's close to the max rating for the auto-trans!

CHECK about the re-tuning of the PCM/ECU to suit the Pressure vs. Vacuum and the extra injector

Looks like JDM Monkey hasn't been on since Feb. I wonder if he is still playing with his VX. Since I am thinking about doing my own mid mounted turbo kit, I would LOVE to hear some of his details.

AEM FIC piggy-back engine management appears to be powerful enough to give us everything we need!

Some comments about lag, were the original CATs still used on this system? If so, they could have been a MAJOR contributor of this lag! You really shouldn’t have CATs before the turbo! Now, it isn't 100% legal to move it after the turbo ether, but lets face it, most of us will not have to deal with CARB ;).

While you could get away without an intercooler (under 10 psi), it can still help you! With intercooler, you will be able to ether run lower octane gas and/or run more aggressive timing. So I wouldn't dismiss it "just because you can".

I think that engine management is THE most important part of well executed turbo/supercharger system. I think I will start by installing AEM FIC, wideband O2 sensor and larger injectors, BEFORE I actually install a turbocharger. Learn how to tune it and only then install the turbo, which is actually the easy part of this job ;).

I wish I didn't live in Cali sometimes it really bites!!

[jdm monkey]

Sorry guys I've been busy at the shop. Another option would be a Rotrex supercharger set up. It is easy to install and very compact. We have successfully fabricated a kit for a Lexus GS400 and can be easily adapted into the VX. I anticipate the kit for the VX to be around $5800.
Here are some pics to get an idea how the setup looks like:

I love it! It looks like the Rotrex fits a lot better than the Powerdyne that Morgen-Tec was using in his Axiom...

good workmanship and design on brackets, measure 7 times before making a cut/hole/move/install))) will make things work and look nice.

I have a few questions:
How much boost?
What engine management is he using?
Usually, a draw through MAF with a non-recirculated BOV will cause issues with stalling. Does he have this issue?

Aw Yes Please.....

[rtormet]

I really want that Rotrex setup! Holy cow

[VXCanada]

centrifugal superchargers won't produce as much torque on the lower rpms as twin screw SCs do. They do produce good top end HP though. IMO low end torque is much more usable. Hence a twin screw or turbo setup would be much better. That's what pretty much every OEM is doing FYI on FI cars.

Roots - very chip and big torque to the lower rpms!!! I can do 6-7 sec, with magnuson MP 90, but my 4l30e not like this :-)))

[Leon R]

Have you tried upgrading your 4l30e with parts from Level 10 (or some other performance transmission shop)?

[NikitaKoval]

no I did not make any modifications. what is level 10? I plan to install the switch kit available on ebay.

Level 10 is a high performance transmission shop located in New Jersey, USA. They make rebuild kits as well.

[NikitaKoval]

Who used parts from these kits? has anyone modified their automatic transmission? What is the feedback?

what can you say about this ebay set?!

Nope. Not touching it with a 20' pole. I've seen very, very few good things come from modding a n/a car for forced induction. And it's even worse when the n/a has such a small cluster of vendor support--that you're having to fab everything & find working solutions for everything...on your own.

I'm keeping my VX's powertrain 100% stock.
