I love the power of my car. But of course I want more, can I turbocharge my 3.1. And if I can how much will I have to spend.

 

yes, more than you think or want to. how exactily does a turbo figure in to being posted on the transmission drive train board?

 

they made some turbo 3.1 grand prix .. only for a few years (91 is one of those years) on some ste models. I am sure you could use alot of those parts but, since is is a fwd it will require custom fitting to fit you rwd

 

How many of those Grand Prix's were made and can I just find one in a junkyard or do I have to go th GM

 

there aren not too many around but, I know of two differant junk yards by me that have one. the only real problem I can see is they use the factory fwd log. manifolds which I think will aim right at you serp setup

 

That sounds like more work than it is worth what would you do instead of the turbo

 

2 more cylinders :lala:

 

ehh just make your own kit. fab up new manifolds thats meet together at the turbo. im not sure on what turbo would be best, mabye a single t3 with a smaller exhaust housing or something.

Be innovative with it and have fun.

 

The turbo 3.1 was only available in '89 and '90, in the TGP and STE Grand Prix, U.S. option only.

About the only part you could use from it is the turbo, and maybe the FMIC, along with the intake tubing that would need to be cut and rewelded to fit the longitudily mounted layout. The manifolds won't bolt up, and even then the out lets point at the wrong places, at your power steering pump and air pump. You might be able to use the ECM, but even then they were only available with auto trannies, and other changes to the engine would need to be made, like the EGR, it's a different type than the F-body uses, along with a few other changes. The ECM also uses different connectors so those would need to be changed. The TGP/STE used a Garret T-25 with (IIRC) .67 comp A/R and .68 turb A/R.

I would look at a T-3 at least, I am using a T-3 from a mid eighties Turbo Coupe, T-3 with a .67 comp A/R, and .69 turb A/R, I am considering upgrading from that though, with either a full T-4 that I have or a hybrid, using the parts that I have.

It will take some time, and lots of planning to build a turbo system for your car, and a lot of compromises to make. Read as much as you can before buying any parts, and it will make the entire process go a lot smoother.

Maximum Boost by Corky Bell is a great book, along with Turbocharges by Hugh MacInnes.

 

I've got my own welder so it will not be out of the question to make my own setup. I've allready made my own altenator and tensior mounting brackets.

 

easiest way to do it would be to make log style manifolds, you cant get any easier to make than that.

something similar to this....



you could probably find a flange to build off of from a custom header place...if not, by sending them an exhaust manifold gasket they could easily cut you a flange to start with. The rest can be made with thick schedule 40 bends and t's. They are really thick and easy to weld.

like posted above do some reading. Internal wastegates will save you some money and you can get a cheap bosch blow off valve for less than 10 bucks on ebay or in a junkyard.

and here ya go for a bunch of junkyard IC dimensions.

i still say add 2 more cylinders .......then boost.

 

i THINK stahl headers has 60* v6 header flanges.

 

That's a lot easier than I thought it yould have been

 

If I am running one turbo will it mess with the engine if I tap it off one side or the other

 

if you run only one turbo you will need a crossover pipe to y both sides together. you dont want a turbo running off only one side of the engine.

 

This is how I routed my exhaust:

Left header and crossover pipe:


Right Header: (crossover attaches to the connection towards the camera)


Here is the system as I was tacking it together. (Don't do as I did, use mandrel bends, I was in a hurry, and just needed to get it running)


And this is where the turbo sits:


Even though I used a FWD aluminium top end a similar lay could have been used with iron heads, but I believe the strut tower is in the way in 3rd gen F-bodies to have the turbo beside the engine, the best place and most common seems to be farther forward, just behind one of the head lights.

 

That top end conversion how did you rig up the coil packs I cant get it to work on mine if you look for irocbirdbuilder and another maui blue rs among us it's in the v6 thread you can see my engine and my road block

 

My grandfather made me a custom crank trigger, my crank had the notches, but my block, being from an '86 S-10 did not have provisions for the sensor. I also wanted it to be adjustable. I then used an ECM that was used in a vehicle that was equipped with DIS from the factory, personally I would have rather used a distributer.

 

Do you think you could tell me what I am doing wrong with my conversion

 

Here Is what mine looks like so far [IMG]Engine[/IMG]

 

Sweet...

e-mail me what you have done, and what you plan to do, along with a parts list of what you have used, everything.
