Hi everyone I have issue with my car
Recently Ive installed turbo kit precession GT 2871 turbo BB , 725cc ID injectors, 4 bar map sensor, Log headers, AEM V1 ECU, Oil relocation kit , (filter is in the from below headlight) Wallbro 255 fuel pump.
During tune we could not get it to go into vtec, It would act like rev limited cut off every time it would reach vtec, We changed it to all diff engagement points , at 7 k at 5 k etc still same results, gaped spark plugs to 0.023 same results
Recently I've installed my oil pressure gauge ( gauge was like 70$) mechanical one
and my readings are when car is warm at 20 psi idle and at 3k its at 63 psi it get to 80 psi at 3500 rpm i think and it never go past 80 psi regardless of rpm.
My Vtec worked 98% before I installed my turbo
car has little over 80k miles ( Oil pressure gauge is at Oil pressure sensor location, I also had it on sandwich plate where filter is on the block ( same results)

Im lost of what else it can be and Im concerned about my oil pressure being too low. as i read somewhere that it should be 35 at idle and 85 at 3k rpm.

(We also checked vtec solenoid it gets 14v at when you hit vtec rpm.)

 

Have you found the issue yet? I Just installed the hot side of the turbo, so the engine is not getting any boost yet and I am having the exact same issue. AFR is looking spot on, no CEL, everything checks out but its cutting out at 6k RPM. Also the car seems extremely slow going up to 6k rpm. Right before the turbo was installed the car drove perfectly.

 

have you found the problem ? I have the same issue

 

You know, the last update (prior to your post) is 3 years ago. Maybe, start a new thread? What specific setup you have on the car & what are the non-VTEC issues.

Thanks!
