I have a GS-R swap with the JR S/Cer. The problem is when I race my car. When I am driving in any gear around 3-4K rpms and right after I step on the gas pedal to go WOT, it makes a bubbling sound and it lags on the acceleration.

I can't figure out what the problem is because this is the first time it has happened. Can anyone please help me out?

if i can understand your choppy english, you have a supercharged gsr and it bogs above 4k? is it tuned? what injectors are you running? what ecu?? sounds like its not getting enough or getting too much fuel, or something could be wrong with the timing or spark

Sorry about the crappy english.

I have 450cc injectors and I bought it from some dude who got it dyno tuned on a stock ecu with an AEM adjustable fpr and a V-AFC2 (I know this is a bad setup but I don't have the money for hondata yet ).

But I think I found the problem. My fuel pressure is only 30psi. Isn't it supposed to be at 45-50ish?

Anyone?

take out the vafc, order a chipped ecu with a burnt chip to run your setup, then save up to get it tuned on chrome, [freak] hondata

what type of ecu should i get? and what do u mean by "burnt chip"?

please excuse my lack of knowledge, im new to this.

Pure Sol

By burnt chip, he means a chip that has a specific map already implanted on the chip. As far as ECU I hope you aren't running the sohc one...

LOL! No I am not running the SOHC one. I am running on a p72 ecu. But if I am planning to keep the P72 as is, what would be a good alternative? p28?

Pure Sol

As ^ he said a "chipped" (burnt) p28 would do wonders for you, talk to the guy who owns Phearable(sp?) I believe his name is John if I remember correctly. He should be able to help you out not to mention real nice guy to talk things out with.
