Getting More Power: Super/turbocharger?

[ItsVince725]

you can pick remanufactured 3800 M90s for $300-500.... it cuts out over $1000.

if you want to hit a junkyard, you can usually get them for under $100.

Yeah, cutting out at least a grand of expense would make it a much more worthwhile idea.

Of course, then I wouldn't be able to decide between a SC 3100 and a NA 3400.

[robertisaar]

SC3400 or 3500 would be my vote.

SC3400 or 3500 would be my vote.

Well if a manifold that allows mounting a M90 to a 3400/3500 comes out, that can be an option.

But a 3100 manifold wouldn't fit a 3400.

[robertisaar]

the large port 3100(00+), 3400 and the non-VVT 3500 UIM are all interchangeable.

I dunno what motor Alero is running.

I doubt a supercharger would fit over the 3x00 without needing a large hood scoop. They fit better on 3800s because of the 90* V I think. The MP90 is mounted to the side of the engine, and appears to use a stock intake.

[robertisaar]

the MP90 is normally mounted on top of the engine as well. they will work in any position though(as long as you can support them), just like the M90.

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.

You can weld the flange right to the cross over. Not ideal but it works pretty well for low boost. That was my first turbo crossover attempt. I eventually ditched it for a better crossover setup Tig welded.



The easiest turbo might be a remote mount set up. The ones that put the turbo near the tail pipe. Packing in the piping, turbo, wastegate, etc is tough in a tight engine bay. Especially a Fiero, ehh ericjon...lol

Have you considered NOS? That can certainly boost power.

[ItsVince725]

Nitrous is not something I'm into.

I want power all the time, not just a shot of power every once in a while. Plus the added torque one gets with a nice supercharger.

Turbo, super or NOS...they all increase torque. The super has boost early on but cost roughly 30 out of every 100 hp boosted. The Turbo is far more efficient with less parasitic waste.

A turbo can get into boost pretty quickly if tuned and matched to the engine right. The advantage a turbo has is they can cruise highway and help save fuel by utilizing exhaust energy otherwise wasted by increasing VE.

If I had a choice, I would go turbo. But thats just me, superchargers can be lots of fun too.

Putting in a turbo seems like quite a bit of work...

But if it produces more power with less parasitic loss, it would be worth it. I just don't like NOS because I want my power all the time, not having to push a button to get more power.

Not if you buy this...

Just a sales pitch here lol

[TGP37]

The work isnt too bad really.

Get a cheap welder so you can tack weld a box and turbo flange to the crossover. Tack weld a piece of steel over the rear manifold out.

Route the turbo out to the down pipe now separated from the rear manifold. Again only have to tack weld the piping.

Find a welder who can tig weld the tacked up pipe.

After that, the rest of the mods needed....like fueling is required for any boosted app.


Honestly, I think supercharging a 60v6 would be harder to do. But they all are work. Cause if it was easy, everyone would do it.

This, because we don't drive Honda Civics and have 10,000 bolt on kits to pick from. Everything to boost a 60v6 (that didn't come from a TGP originally) will be pretty much a custom deal, and custom=big bucks.

The biggest obstacle I feel is welding. After that, a good pair of hands and a firm mind to design the thing.

Even then, I had some skill welding with a mig and still screwed up my first turbo manifold.

Edit: Looking back I thought I had welding skill. With lots of practice on the tig, I finally got it.
