4efte forged vf34 boost advice and injectors

[ktsirigotakis]

Hi all

I have a friend and he has an ep82 4efte 1.3l forged and head stock! We have all ready manifold and vf34:rockon: and we would like what boost to work the beast and what injectors. I have good skills of tuning the ecu this car has a piggy back ecu similar to unichip +-50 injectors by modifying the map signals and ignition timing adjustment! We have also a drag spec transmission with Cusco lsd :drive: (built from a very famous tuner in Greece)

seems they can run around 18psi - 21psi and generate about 300bhp or a little more depending

injector wise, maybe 460cc -550cc range

I just bought some blue impreza injectors 440 what do you think? Do you know how much can 4efte rev at the moment the car revs max 7403 and i can modified it to 7600! (Crystal replaces)

Also we are running single pipe exhaust 60mm (front bumper)

The VF34 is the same as the VF30, apart from it is a ball bearing unit rather than journal bearing. Spool time is reduced by around 300rpm, and the turbo will max out at around 360bhp.

Injector wise it would probably be best to use 500cc. You will prob need to rev the engine to around 8000rpm to get full use of the turbo.

Yes it's the same with the vf30. we had already on a ep82 4efte forged this turbo and you don't imagine what the car was doing it was forged, fcd, fpr, and caldina injectors 525cc no engine management 1 bar boost full boost 4000rpm yes 4000rpm!!! But engine cr: 9.5:1 afr idle 12 cruse 12 wot 11,8 (terrible). Look gays i have tested rev limiter at 8000rpm with crystal replaced and the engine couldn’t rev more than 7800, we never heard limiter!!! i am building now a ep82 stock 4efte with stand alone ecu i let you know if this one can rev 8000 but we will install 4 coil. I believe that the springs can't rev so high!
