i just got a safc and my injectors cleaned. 550cc in primaries and 680cc in secondaries. if i wanted to upgrade my turbo, what compressor wheel should i use to get around 300hp safely. if i even can.
an upgraded fuel pump will be on the way as well. oh and my wastegate is ported.

 

300 = 720cc secondaries
680cc should put u into the 275.

should get a t04b or e compressor. .60 in the a/r seems about right for 300hp.

 

Are you referring to 300hp at the wheels or at the flywheel. I put down 232 rwhp on stock injectors and my a/f was still in the mid 11's.

 

well id like at the wheels. even more so if you put down 230. what did you have done?

what are the difference between these wheels. to4b to4e. i dont really know much about turbo specs.
