I've got hold of a low mileage STI 3 engine, to replace the tired stock engine. The car is mainly used for track days, and the reason for choosing the STI-lump is the 7900 rpm redline - as it suites the JDM 6MT perfectly.

In other words, I want to utilize the extra rev-range - and it has to pull strong all the way to the redline. Power goal is ~ 320 bhp. The engine is sold without a turbo, but I have a VF28 from a V5/6. Is it too small to fullfill my wishes? No FMIC, but an STI8 TMIC.

IHI VF28
(425cfm at 18psi, 250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the JDM V5 Subaru Impreza WRX STi.
Expect to achieve full boost with the proper mods and a quality tune between 2800-3300rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and proper engine management is highly recommended for all vehicles.


Looks like it could be ideal for your needs... so long as it can hold boost all the way to the redline, of course. It certainly spools up nice and early and easily flows okay for 320 fwhp, etc...
