Rb20 Problem?

[Ben M]

so i have an rb20, fully stock, side mount intercooler etc. now when i rev it up and drop the clutch or go to do a hillstart, it nearly dies, then slowely revs back up. i checked for a leak in my piping or bov, couldnt seem to find one? i checked my bov and nothing. thought maybe the spring might be too loose but i dont know? makes an awfully big spooling/sucking noise at even quarter throttle. so i dont know why this could be?

i also have a problem with it missfiring on boost between 3 1/2-5 grand, then pulls fine. i bought new plugs. NGK BCPR6ES. gapped at .8mm. still did it. checked the cam timing, set it at 15 degrees. still does it. now im using an rb25 engine harness, which is a little stupid as now it idles at 1.5-2 grand! but 4th, and 6th injector are the wrong way around on the ecu. so swapped them around. still does it. i'd heard about hairline cracks in the coilpacks, so ill have to check them, but if anyone else knows of any other reasons which it may be doing this i'd love to know so i can try them.

cheers, Ben

Spooling noise could be an exhaust leak, anything from the exhaust manifold gasket to broken studs/nuts relating to the turbo.

As for the hillstart thing, could be a slipping clutch or intake related (dirty/bad AFM, intake manifold gasket leak etc)

As for mis-firing, could be the ignitor (if it's the series that doesn't have the ignitors built into each coil), though they usually work fine when cold, it's not until they're warm they start causing problems.

yeah ill have to check the exhaust manifold for leaks etc. as for hillstart thing, the car had a n/a in it before and the clutch was fine, the clutch in it is supposed to be able to handle turbo, and it drives fine when im rolling if i chuck it into first and give it some stick, only when taking off on a hill. ill have to check the coilpacks and ignitor. and afm and maybe clean out the t/b
