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).

id probably be interested once it was proven... id still rather get ahold of a supercharger though
Are the Alpine kits no longer available? They cost just a little bit more and have already been tested and proven.
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.
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
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.

If there is one thing I like more than superchargers, its turbo chargers! Work on the details, you've gotten my attention
Better figure on a tranny upgrade to go with it. 50-100hp boost will grenade the stock one.
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
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.
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.
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
Is that an accurate page?
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.
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: )
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.
ok, updated.
Prototype kit construction will start this spring. I'll keep you guys updated.
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.

As promised, some pictures of the prototype turbo kit 75% complete....
*some items may vary from the actual kit.

Here's the turbo for the proto. kit

Charge pipe...

Proposed chargepipe routing. It requires cutting a hole on the inside fender area.

Return line tapped on the oil cap. This is for testing only, the kit will have a quick release fitting.

Nice work....
keep us updated
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.
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....

Jdm...Looks good, I've been trying to find pic's of a guy in Japan that fab'd one about in the same location as your doing. It might give you some idea's on mounts, locations etc. If any member has any pic's of the Jap VX w/turbo post them. Keep us posted..
jdm monkey, nice work...

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

Exhaust cutouts=best of both worlds methinks
Think?? I've no experience:o Only negatives with turbos in muck
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. ;)
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:)
