Miller woods 2.8 manual turbo kit (Page 1/2)

Any interest? Exhaust is big, might have to put on a pallet. Turbo spins free, no shaft wobble.


Has a programmed 85 ecm and knock sensor module

Might be very interested.

I have auto, but that means I can use stock exhaust, rigth? What else is different.

I have a lot of questions about the turbo kit. Googling around can't find good link with all the details. Got a suggestion?

There are quite a lot of differences between the manual and auto Miller Woods/Design One kit. The crossover pipe and turbo mount location being one of them. I've got the Design One setup on an a GT automatic.

I've been meaning to scan the install manual into a PDF and post it for posterity, have to find it buried in the garage somewhere first though.

I was researching engine swaps long before I even bought my Fiero last month. There are a lot of little things to do to the body and suspension before I consider an engine swap, but i planned on getting it done in a year. So this turbo kit would have to be very cheap and simple for me to even consider it. It might postpone the engine swap, but I don't see getting the same power increase and long-term dependability from this turbo as I would from a new engine.

Plus "turbo" usually doe not go well with "35 year-old engine".

I would not advise putting boost in a stock 35 yr old engine. The cast pistons in the 2.8L even when new were never ideally suited for turbo applications and now have had missions of cycles on them. I would put this kit on a fresh rebuilt engine with forged pistons and a turbo cam profile. I would guess 190-200 horsepower would be possible.

The only way it makes sense is if I just write off my current engine because I know I will be replacing it anyway. I could run the turbo until I blow the engine then re-sale the kit here. I just need to get it cheap enough so that I could get my money back.

Does it have an intercooler? I see a silver square thing, but that might be the ecm. No intercooler really limits what you can do with boost.

Do I need a new fuel pump or bigger injectors?

No intercooler w this one, could pipe one in. There was an intercooler option, not a whole lotta info on these tho. Does come with a fuel block w big injectors, forgot it in the pic.

IRM put these turbos on Fieros back in the day with no issues! They run like a scaled dog, Dont be afraid to go ahead and install one! Regardless of what some people might say.

There is a lot to doing it right. You need to add more fuel and pull back some timing. Luckily the stock compression ratio was really low (8.5:1). That makes it easier, but engine management is still an issue. With no intercooler I doubt they made much boost.

Do you know any of the specs?

It has a programmed computer, its a plug n play kit. The guy I bought it from seemed to know about these kits. He said 8lbs boost max.
