GI: Turbo Kit

[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

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

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.

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.

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.

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.
