Default MD321S

Is anyone running one of these on a uk 2 litre impreza?

If so what sort of power are you getting and what is like as a road use turbo for the car?

Thanks
Jamie

You should fit the 321H on a std 2 litre engine, 400 ish bhp mapped up properly

cheers

how laggy will it be? i have kinda bought it lol.

Im running:
unequal length stainless steel manifold
Forged pistons
Sard FPR
440 injectors
Bell mouthed decat downpipe
Sti genome exhaust
Uni chip remap
HKS Induction kit

I am running an ihi vf22 at the minute and it doesnt come on full boost until about 3500, will it be MUCH laggier than this?

What sort of psi will the turbo be able to run and what sort of power will my engine be able to take never mind the gearbox?

440s not big enough unless you run very low boost

I would estimate 4200rpm

boost more than engine can take

your spec seems pretty low to even take this turbo, but once mapped on a 2ltr if this turbo is laggier than the T model ??? I would expect full boost at around 4600rpm ???? depending on what your final spec is

This isnt a drastic move but the turbo will be laggy on a 2 ltr, your gonna have to change ecu, add possibly an AVCR change quite a few of your other parts and add possibly a better gearbox???, plus I hope you have an STI as it has the 8k rev limit so you have more time to make the power The only bad thing you have done is buying a big turbo in error?? but if you mod well I bet you could possibly like a lagier turbo ?? My car is laggy I dont see full boost till 4k but after that on a good turbo

sorry for a slight hi-jac, im running at tdo5 16, with fmic and reversed inlet and hitting full boost (1.4-1.5bar) at around 3600rpm, is that classed as laggy for a td05?
