Getting More Power: Super/turbocharger?

[ItsVince725]

At some point in the future, if I can keep the old 'Lark running that long, I'd love to either supercharge or turbocharge the old 3100 SFI. My question is, would it be more cost effective to try and hunt down a 3400 DOHC from a Lumina Z34/Euro 3.4 and tune that up? I don't plan on putting several grand into the car, so...

It's easy to spend several grand on building a turbo setup. Supercharger may be cheaper.

Can you get a scroll supercharger for a 3100, similar to the 3800 L67?

where are you getting a supercharger for a 60* cheaper/less work than a turbo kit?

[caffeine]

Just because of less piping and no messing with exhaust. Junkyard supercharges probably cost about the same as junkyard turbos.

Still pretty much everything needed to make it work is custom either way.

this is why I would go turbo instead, way less machine work, belts don't have to be aligned, ect...

but to the OP, what year make and model are we dealing with?

I know nothing about doing any of this plumbing stuff...I assumed someone out there made an upper intake manifold/supercharger assembly that would just bolt right to an existing lower intake manifold and solve that part of the plumbing. Granted, even with that, I dunno where the air intake and throttle body would go...

I guess when it comes to an engine like this, you have to custom plumb everything because supercharger/turbo kits straight up don't exist.

I'm not aware of one, but I think Mars had a supercharger kit on his cavalier. might shoot him a PM.

Centrifugal S/C. Replaced the A/C. Ran it with a intercooler. It has its own oiling system that needs a small oil cooler (Rotrex brand). Only problem is you need to rev high to get power out of it so you really need to build for higher revs. He was shifting at 7k RPM's (manual trans). He also had minor port work with a cam and proper lifter springs to go that high in rpms. Headers with a 3in downpipe with a cut out...

Probably better off to wait for AleroB888 to finish with his front mounted MP90 and hopefully he would let the castings out of the bag so that everyone else can do it aswell for cheaper. Cause I can see that becoming a very popular thing to do with 60*'s if it all works out with him.

It might be possible to modify a TGP turbo setup for reasonably cheap, however, the manifolds would be somewhat restrictive and the stock T25 turbo should at least be upgraded to a T28. Should make good power over stock though

you can open up the TGP manifolds to the 3x00 ports, but it leaves almost no sealing face area near the corners of the ports. it's not something I would recommend, what I would consider is blocking off the output of the rear facing manifold, and fabbing up a new Y pipe to the turbo.

I recommend installing a 3400 and obd2 before considering a turbo or SC swap.. I wish I had done a 3400 and obd2 before I built my first turbo kit. But if you want to do either a turbo or SC swap, it'll be several grand.

considering he whipped 12PSI out of it, it is most definitely an interesting option to pursue.

hopefully, we can go a step further and just use the M90s from the L67s and make the process even cheaper to get into.

Wait a sec...I thought he was using the MP90s from the L67's....
