The Supercharger off the GP, is most likely the one off of the 3800, and it has an intake manifold that sits ontop of the engine, where the charger mounts. No such setup exists for the 3400, so unless you are dang good at fabrication, you will not get a supercharger that sits ontop of the engiine.

From what I have seen the guys on this forum do with a turbo, is also all custom fabrication, but look alot easier to do (although I personally still wouldn't call it "easy") It seems like once the two headers meet, you route the exhasut to a trbo sitting behind your engine, and then route the boost to your intake. Of course the airbox and battery are removed, and I would suppose the battery is relocated to the trunk. You would have to figure out how and where to position the turbo, how to bend and route all the plumbing, etc. etc.

I still want to find a good fabricator and figure out how to mount a supercharger ontop of the engine. maybe cut the intake manifold up and go to town with a bunch of aluminum, and lots of tig welding???? But that project is for a later time.

thanks alot of good info...

all sounds hard and quite pricey

if you wanna go turbo,the good in it is that you can do it the way you want it to be,not really hard,piping intercooler,turbocharger,BOV,wastegate,couplers,cl ips and some custom work for the downpipe and turbo manifolds and if you buy it at good price its not expensive at all!!for the tuning,i cannot help cause i dont even know what it is really(never saw someone do it)!!

it isn't hard to do, actually it would be really easy to do, but who the hell wants to run around with a big ass hole in their hood with a supercharger sticking out, or who wants an 8in cowl on an alero to hide it, it would look pretty rediculous, so yes the front mount is your option and that in itself isn't that hard either, just takes money and time, and if you have one you usually don't have the other....

But I would try to get it fitting low onto the engine. Might need to make a complete custom manifold, or modify the S/C for the 3800 to fit the 3400. It's getting it low enough on the engine that will be the fun part. Never said it would be easy.

have you ever looked the UIM? it is about as low as it is gonna get and be functional. It maybe could be moved down an in, but that would be a huge stretch and your runners would be almost horizontal.....and all this is without an intercooler.....that brings up a whole new set of problems.....

I realize that, but hte one on the 3800 is done like that. The Supercharger bottom is actually the intake. I realized you can't intercool it then, but then again, ANY supercharger that sits atop the engine can't be intercooled. That is a big advantage of a turbo, you can cool the compressed charge before it entering the engine.

so many people say turbo before sc because of costs what would a turbo setup run price wise?

2k is your low point. maybe 1.5k if you're really lucky. and that's a used kit.

why is this stuf so expensive? seriously tho are materials to make the kits themselves really that costly?

Well a good turbo is like 1200,bov-200ish,WG-250ish,Inter-cooler any were from 100-500,piping a few 100 and all the other random vacuum lines and oil lines 200ish prob more turbo manifold 225 from ebay way more for a custom one total atleast 2.5-3k for everything new

you really need to rethink what you think you know about superchargers....

First off, the 3800 is a totally different motor, and was designed from the factory with a supercharger on top, so yes obviously they would make it fit. And secondly there are a ton of superchargers that sit on top of motor with intercoolers. And lastly, why the hell would you want to use an m90 from a 3800 motor, other than they are cheap, when you are going custom the m90 is low man on the totem pole, they are ineffecient and couple that with not having an intercooler and they get even worse, there is a reason i ditched the hEatons.......

On an engine setup with the supercharger ontop of the engine, you cannot cool the air going from the supercharger to the engine. You would need a pretty massive and restrictive adapter to do it. You COULD cool the air BEFORE it gets to the supercharger, but then it wouldn't be an "intercooler" it would just be a CAI!!

wasnt there a buick with a 3400 sc?

yes you can......most call it a sandwich intercooler.....seriously i am gonna have to slap somebody......

look at this there is even one for the 3800, OMG!!!

m62, yes
3400, no

Cliff8928 · 04-12-2009, 02:59 AM

There wasn't a production supercharged 3400, only concepts.

You may want to check that...

Yeah seriously, I hear ya.

The LC3 too... This was probably the basis for the LS9.

does anyone have a sc or turbo kit for sale?

stay away from it!!!
