I have a 1984 GSL 12A rx-7. I bought a turbo kit with intercooler for a little over $400 on ebay. I need a box to fit over the air filter that has a spot for a turbo tube to hook up to. I think that I found a box from prochargers and then I am going to hook everything up. WHat do you guys think? I was going to buy an atkins supercharger but the price was sooooo much more than the turbo kit was. Do you guys think that it will work? Thanks

What exactly did the kit come with? Is it blow-through or draw-through? What carb are you planning on using? We need more info before we can say wether it will work or not. And besides, I'm curious because I'm in the process of collecting parts for a draw-through system on my engine.

How about the exhaust manifold, and the exhaust after the turbo, and the oil feed and dump? What about the intercooler piping? Have you calibrated the fuel system for the extra air yet? How far in the stages of this upgrade are you?

Ack! Why a draw through??

REVHED

Why not? It's cheaper to set up, easier to tune, no special mods required to carbie. Picture this. 45mm Weber with adapter mounted directly to inlet of '90 T2 turbo sitting on custom manifold with the turbo blowing through stainless piping into custom made plenum mated to IDA style intake manifold. Exhaust will be 3inch mandrel bent straight from back of turbo. Obviously you can't run an intercooler which is about the only disadvantage of the draw-through system but it shouldn't be a problem since boost will be kept pretty low.

its a garret turbocharger that was remanufactured and it came off of a v6 3.8L car. It comes with a 4 barrel intake maniflod and everything else needed already assembled and I hope it will work. Do you think that it will work because it has a 4 barrel intake manifold? I got it cheap and I really hope it fits because My car is at a shop right now being painted and I dont get it back for 2 weeks. Thanks

heres a picture of it minus the intercooler

buick regal is what it came from, will it fit?

I seriously hope that it works because if it doesnt, I wasted my money. If anyone even has a thought, please tell. Thanks

Bottom line is it will work!

Anything can be made to work with enough fabricating and/or money!

if it is set up for a four barrel holley you should be able to get one fairly easily that will bolt right on, If it set up for a quadrajunk you will need an adaptor they make for such things.

You will need a custom exhaust manifold/header and I hear those things are quite pricey!

It looks to me like you will need a custom intake manifold also(if I am looking at your pic right)

I would like to see more pics from more angles if at all possible.

sounds like a challangeing and fun project to me!

keep us informed

yayarx7 is right about the manifolds and downpipe.also i'm quite familiar whith what you are trying to do,so you also have to modify your front cover for your oil dump and buy an adapter and line to link the oil sending unit to the turbo(can find at any plumbing supply store)and if the turbo also take water you have to tap into the water return line.on another note keep the boost down because that high compression engine will over rev that turbo under higher boost levels unless it has a high a/r ratio.on the 84 gsl we built we used a to4e 60-1 turbo and the engine would boost 15psi in neutral with boost controller turned all the way down,but the engine was ported and polished for racing.under load the boost shot up to 28psi@10,000 rpm but in turn the turbo didn't last too long and will be getting a t-70 replacement next year.so to sum it up we took a factory high compression 12a ported and polished it,custom made our own manifolds when the engine was originally a draw through system,but was later changed to fuel injection because the car had a tendency to break up when racing upgraded the ingnition and fuel supply and last but not least installed old school haltech ems.as for the performance the car bent the factory suspension on the first run we knew that was gonna happen sooner or later,the best run we had the yanked the wheels off the ground on the launch and about 3/4 of the way down the track the turbo blew the oil seals and part of the comressor blades and still ran a 12.5!

p.s. the factory drivetrain will not last long! we used tII tranny,driveshaft,flywheel and nissan pickup rearend with factory 4.10 gears.

Yeap!!! Anything is possible, but it's not as easy as it sounds or looks. I hope this picture shows up, but check it out. It's a turbo II motor in a '91 miata, with t18 turbos and greddy intercooler, putting out about 350 rwhp. 12.3 b.e.t. with street tires. We also have a turbo charged 12A putting out about 280 rwhp. Don't have a pic of it but i'll get one.

Here's a turbo set up that will be dropped into a 1974 ford courier.

Nice projects and pics r_ed_line53!

Keep em coming!

A lot of people I've talked to have said it's a bad idea using an intercooler with a draw-through system like yours. Because the carb is before the turbo you'd be running both air AND fuel through the intercooler. Apparently the fuel can condense inside the core and if you have an engine back-fire chances are it will explode like a bomb.

Put that thing back up on ebay and get some of your money back!

i know that water injection messes up the blades on a turbo, wouldnt fuel do it to?

your pic right)


Is there some place that I could buy these things from and what is the cost, price is not an issue, I have money? Thanks

here is another picture

and one more

nevermind, I put it back on ebay and bought a remanufactured 13B turbo and intercooler for $100, now I just have to figure out a way to put it in.
