Hey guys,

mods: Full 3" exhaust, 60-1ct-26, lexus afm, aftermarket intercooler and piping, intake, SAFC, and Greddy ebc.

Question: Will 680cc injectors be too much? or will they be ok.-providing I tune the car. They only have these in stock at the moment i'm my car is getting fixed right now.

Yes, too rich, though the TCCS should be able to correct for it in learned mode. Still, at WOT you're going to be really REALLY rich. If you have to deal with smog test at idle, that'll probably fail as well, since idle is open loop.

Too much fuel +1

I don't know where you live and what emissions you have. For me, my idle passed and my 15 and 25 mph checked passed. with the safc, you should be able to tune it out. I would recommend a FPR to make tuning easier.

when I had an safc and 750cc injectors, my idle was fine and i had to tune out lots of fuel under boost. I was running rich during cruise (12.4).

just my 2 cents

Does this make him a thread terrorist? LMAO:biglaugh:

At what point would 680's be good to go to? I'll have a setup that is close to his and i was going to go with 550's, but at what point are 550's not enough???

Try to base what your HP goal is.. Buy some RC 680's and I'll trade my RC 550's with you. :naughty:

wow, now thats a deal! :sarcasm:

according to the formula I should be good with 550's. I think I would need to rebuild the motor with forged internals before it could reliably handle the horsepower achieved with 680's, its currently rebuilt with only stock internals.

thanks for the link!
