Ok, i know i'm not going to get 500 horses, or boost 1 bar.

Realistically though, how much PSI of boost can one reliably put into the single cam 3.0 with distributor? i dont think of trying to get as much as 20 to 50 extra ponies there.

Heres the suspect, its a 1993 Montero SR with a fresh engine with less then 1000 miles, bored and decked.

Heres the plan, single T3/T4 turbo, 5 to 10 PSI depending what the engine can take.

 

Asymmetric turbo setup, or will you use both banks? Do any turbo manifolds exist already?

T3/T4 usually refers to the flanges on the turbo compressor/turbine housings. So, a T3/T4 is a hybrid design.

I'd imagine you'd want something small, with fast spool, and given that these engines don't really rev that high a Garrett T25 from an older Saab or something would probably work well.

 

Both banks. No manifolds avaliable, will be custom made.

Also, is there a piggyback ecu that will work with the factory ecu? I looked around and all I see is stuff for Honda Toyota and nissan. Hell even GMC has more choices then McDonald's. The t25 seems like the good choice, might go a bit bigger say t28.

 

I don't know if there is a piggyback option for the Mitsu ECU. There is almost no aftermarket support for Monteros.
