just a warning for all u guys turboing ur

[stefan]

if its all done properly rebuilt low comp worked head running 10-15psi should be able to take it well?

im aiming for about 140-160rwkw

sweet another street turboed sprinter in sa! that power figure is easily achieveable with either gze. smallport head ftw! I know this will start a war form everyone that reads this but having spoken to people running 4agte setups and having driven my car with a bigport head then exactly the same setup with a smallport head 30rwkw more, way more torque and boost will come on way harder!!!!!!!!!!! i will never run a 4age with a bigport head again!

interesting... i wander why it did this? did you have the same amount of boost? and the exact same set up, but a small port instead of the big port and thats it?

[JDMJNKY]

EXACTLY the same setup just changed the head same cams everything!

On my old AE86 I was running a standard AE101 Ze small port, with an RB25DET turbo, RWD big port inlet manifold and Bigport to small port reducer plate, adaptronic ECU on 12.9 psi it made 154RWKW but it had reached duty cycle of the injectors and was running towards an unsafe air fuel ratio so was backed off abit.

About to do it all again now with my new project , but might go cams 264 - 272 or maybe 20V head etc this time and more boost .


Cheers

Would 7mgte injectors have helped being 440cc?
