So I know nothing about turbos besides the general principle of operation. I had a buddy who had a 1990 eclipse that has a single turbo that puts out 14 psi. He's selling it for like 200$ My question is would I be able to cannibalize the turbo from the eclipse and use it on the 3800? If so what would I need

 

my boss and i just put a turbo from a 90 saab on his miata we made the header he had to buy a blowoff and an intercooler all in all i think he spent like 350$ (turbo was 150$)

i just got a turbo off a saab and plan on fabbing it up to my 3.4 this winter

(youll also need a boost gauge piping and everything to run the oil lines he also added 2 extra injectors before the TB... why i dont know but damn is that miata quick)

 

Do a search, Musicman is working on a turbo build. Building a V6 that will handle a turbo is not cheap. You need to do the research on what all is needed. No one is going to type the books of information you would need to get everything right.

 

Well I bought this camaro for 200$ and the eclipse is the same price. Its not a daily driver, more of something I want to rebuild lol.

 

How much would the turbo increase the hp by?

 

its a 3.8 running 14 lbs of boost about 40-60 being a stock turbo and the setup

 

Lol 14 lbs of boost to get 40 hp? Not even close.

The turbo needs to match your car. The 3800 performs well with a T3/T4 turbo running around .63 a/r.

6 lbs of boost would net you right around 60 HP intercooled. But you'd have to do some work to build up your car to handle anything more than 6 lbs.

I'm fabing an M90 to go onto my car and I'm going to tune for 10-11 lbs of boost on a stock bottom end and see if it holds. It will be hard to tune for without an intercooler involved but it can be done. M90s generate a LOT of heat so I will like make a small cowl to draw heat from the top of the car.

All in all... Would it work? Sure if you do enough custom fabrication. You SHOULD get an IC to go along with it and they aren't cheap. You'll also need injectors, a new PCM, wiring harness, all the pipe and tools to make it work along with a custom exhaust. Meaning you'll need a gasket set and some flange gaskets for the turbo and a custom intake. Not to mention you'll probably have to upgrade your fuel pump and rails to handle the extra fuel requirements ^_^ Boost means more fuel. It takes more fuel for us to make 300 RWHP boosted than it does an LS1 to make 300 RWHP N/A.

Want me to stop there? You cannot run 14 lbs of boost on your stock car. I'm leaving out so much **** that you would have to do to make that work...

 

I’ll bet I could buy a Z28 with a blown head gasket and repair it for less then the custom Turbo exhaust would cost. That is unless you can make custom headers and exhaust systems yourself.

 

Exactly. I could do it... But could you (OP)?

 

How long would a stock original 3.4 hold up un 14 lbs of boost? I think if it was in really good shape I would guess about 60 seconds. From what I have read your not going to add a ton of power to a 3.4 even if you dial it down to the point it will not blow the motor. The biggest problem with the 3.4 is the exhaust side of the head. Even a larger cam will not help because the limit is the head casting itself. It can not get the cylinder empty when it does not have a turbo charger. Adding a turbo will cause more back pressure making even harder for the cylinder to get the exhaust out of it. Do a net search of 3.4 and turbos and see what you find. You will not find many. Its not because no one want their 3.4 fast or that there is a shortage of turbos. Its because turbos and 3.4 do not equal fast. The heads are the bottle neck on the 3.4. You need to fix that bottle neck before modds are going to do much for you.
