lately my car has been jerking back n forth between 1000 and 3000rpm and is getting annoying...

it only happens on the low revs, as when the boost kicks in it pretty much goes away...its a r32 with rb20det....

no mods other then r33 turbo, front mount, exhaust, safc...10psi boost....just began doing it lately n wasnt always like that!!!

GOT ANY IDEA'S????

THE IGNITOR PLUG WAS LOOSE AND WAS MAKING RIDE ROUGH AND AS THOUGH IT WAS RUNNING ON LESS CYLINDERS....

FIXED NOW...BUT ON IDLE REVS SEEM LIKE THERE MISSING...GOT ANY IDEA'S??

what does your car idle at? does it idle high every now and then? does it only do this when car is idleing high?

my car does it when ideling high, it idles high when the wheather is colder, best take it to a mechanic as thats what i will have to do.

i suspect in my case it could be my TPS or CAS, because i have already eliminated the AAC by cleaning it.

probably try cleaning AAC see if it fixes the problem.

I am having a similar problem as well, after it has been driven around for a little while. It starting to get worse, started off as a intermittent problem. If I hold my foot on break and put a little load on it at 2000 rpm while driving, I can feel it surging. I was on the pathway of a sensor as well.

Please Read my blog.

      Rb26 iron block limit

      By Curlyfred · Posted

      Aye, everything is being touched and all the parts that are responsible for the oiling issues are also fixed. (Crank collar, billet prp oil pump, head return to sump, yada yada yada)  Everything used is of reputable brands like greddy, prp etc. My tuner did mention we’d keep the torque on the “lower” side.   glad to read that my engine won’t blow up on me lmao

      What's this Foreign Object?

      It's a fuel pump. EFI, high pressure, but specs otherwise unknown. A bodge job.

      Rb26 iron block limit

      800 engine horsies is fine. Will need all the obvious upgrades. Rods, pistons, oil pump, big sump, sump breathing mods. Build for revs because revs are power with less stress on the bottom end compared to boost. Keep the torque down in the midrange, either by limiting boost or timing.

      Rb26 iron block limit

      By Curlyfred · Posted

      Hiya guys,    i’m currently in the process of getting my rb26 built. everything is being replaced with better/upgraded parts or oem when that’s good enough (which isn’t alot lol). someone earlier mentioned to me that i’ll be screwed cause the iron block can’t take 800hp (to the engine, not wheels) which is what it’s being built for.  what do you guys think about this, am I cooked or na? The guy building the engine will also do the mapping as he is “the guru of old nissan engines” here in Belgium. I know the mapping makes a huge deal so i’m not concerned about that.    I honestly he’s talking shit cause he’s that kinda guy but a second opinion never hurt anyone! cheers in advance! 🫶🏻

      R-chassis INNER tie rod torque spec?

      By AdiR34 · Posted

      I'm seeing torque specs all over the place for the OUTER tie rod, but none for the INNER tie rod, where it connects to the steering rack. Even in videos, people are just tightening em up as much as they can with a wrench and that's it. Anything tightened down without torque makes me nervous. Anyone know what the spec is for it?
