Install a 85-87 Buick GN Turbo Setup?

[CDNFB]

Has anyone ever tried to install a Turbo setup from a Buick GN '85-'87?

Will this system fit on a Series II engine?

The one possible problem that I can see is that if installed in the Firebird the would Turbo sit kind of high, probably hood clearance issues.

I have seen an engine and turbo swapped from a GN to a 97 Camaro before. Not sure about mounting it on the series II though

Would also have some fun getting the intercooler mounted in such a way as to work with the
fan attached to the harmonic balancer.

There's a member here that did a complete GN/turbo swap to his 94 Firebird. Forgot his screen name.

I've done a setup based on that turbo. Custom passenger forward sweeping header, drivers manifold passes through it, 85 gn t3 intercooled, all exhaust hooked up.

Not exactly what you're looking for but close [img]smile.gif[/img] I don't have numbers yet as it was late in the fall when i got it installed but stay tuned.

No, I meant the actual GN engine swap and the turbo. He had no clearance problem at all with the headers.

At this point in time, the question would be why?
THE WORK IS NOT WORTH THE GAINS...

his screen name is gergwheel. he had to do a little bit of custom fabbing for it. IIRC he had to fab up some motor mounts and a few other things.

heres some pics in this thread..

Yeah i know... I was just letting the guy know i've done similar to what he's asking about [img]smile.gif[/img]

Thanks, great pics! Looks like lots of mod work required. Are those all parts from a GN, or a bunch of parts from other sources configured like a GN?

The GN's are starting to show up in the bone yards now, at least the ones that have been beaten to death. And I was thinking that I could use all the parts off one of the motors (but not the motor itself)like the exhaust manifolds and crossover, turbo and wastegate(rebuilt of course) Intercooler, harmonic balancer fan, Brackets, etc..

Seems like it would be less $$$ and effort than it would be to try to piece it all together by myself or even to buying a kit from someone (which seems like there isn't one).

Of course, whatever you want to do with your money is a choice...however THERE IS NO REASON TO GO DOWN THIS ROAD at this point in time you will be back peddaling!! It is 2006 the fascination with the venerable LC2 should be left to kit cars etc and vehicles 'endemic' to the aforementioned engine...

THE ONLY ISSUE WITH A SERIES 2/3 is PCM related as far as I am concerned you can go aftermarket...but that is only if you are flirting with HP/TQ in the range of 5XX/6XX and want to keep the drivability...period!!
This path my friend is redundant at best...again it is your money :D
BTW this is not a flame...just a watch yourself alert!!

One other thing is the exhaust manifolds. I am pretty sure that the exhaust manifold from the GN 3.8 is totally different. The ports are in different places so first thing you would have to do is custom manifolds. moving forward through the system you would need new exhaust piping going into the turbo becuase it wouldn't mount in the same place, this would cause you to have to fabricate new intake side tubing to go through a different intercooler because I'm betting the GN one won't fit without say chopping off the front bumper of our car, then there is new tubing on the other side of the intercooler into the intake which is located in a different place.

now if you wanted to do a full engine swap well that's a different story
