Installing a turbocharger

[keith paterniti]

I bought my friends stock turbo from his 87 buick GN. I figure the turbo will have to go in front of the throttle body because there is alot of space. How did you guys plumb the exhaust? Where can i send my computer? Do i need to lower the compression ratio with 9 psi of boost? Will i need bigger injectors? How was the intercooler run? Thanks Keith

do a search, do your homework.

you are in way over your head it seems to me.

Gunna have to agree with Tiago.

To put a single turbo on those cars a lot of people are putting them in frount to the left or right of the engine.
You still have to figure out where you are going to run an inter cooler and you have to have oil lines and coolant lines going to and from the turbo.
With my set up it does not use the cars oiling system, the turbo has its own oil tank, pump filter and all.
The oil return line is some times tricky because it has to use gravity to feed back to the oil pan, in most cases.
Because it is a GN turbo you can get plenty of parts for it like a wase gate and flanges for the exhaust down pipe.
That turbo also has coolant passages some people say you don't need to use them but I think it is all ways best to do so.
But putting the turbo infrount of the tb, I never thought of that. It would only be good for lower boost and would cut down on the intake piping a lot, but that exhaust piping would be a b!tch to run.
By puttingg the turbo near the tb you won't be able to have an intercooler.
You might not need bigger injectors but you will need a fuel pressure regulator.
You can look at my web site for some ideas because I have a 3.4 also but I have twin turbos and a good number of motor mods to get the engine ready to make the most power with the least amount of boost.

I have a turbo from an 87 GN on my car. Forward facing passenger header, stock driver's manifold goes to an x-over pipe, similar to where the Y-pipe was. This gas spills into the backside of the pass header. Turbo sits on the front pass side of the engine. Downpipe goes over-K (removed AC for this), and back to where the normal exhaust goes. (Run it through a loudmouth. Easy, direct routing of the outlet charge to the TB, espceially since you can turn the outlet any way you need.

Not intercooled yet -- have a big one, just unmounted. Actually rebuilding the turbo right now. Anyway, I don't have many pictures of the setup, but I could find and host a few if you really need.

Hope this helps.
