Default reving to like 8000RPM,no rev limiter... possible?

so my buddy bought a 03 white wrx in feb/mar 2006. The car was originally from BC and came already modded

full turboback system, HKS bov, HKS ground wires, Blitz gauges, Blitz short ram, sti intercooler, sti hood scoop, jdm headlights w/ HIDs, lip kit, every suspension mod. He got a good deal!!

So i've identified all these things, BUT heres the question, he can rev his car to like 8000 RPM and the rev limiter will not kick on...WHY IS THAT?

he cant find a ECU(like utec) i dont think he has the accessport cause hes not boosting 17psi.

so im wondering why, one of my friends thinks he has a upgraded cam but i said usually u have to tune ur car w/ a upgraded cam or else ur car will idle funky(thats what happens in the lancer community n e ways)

anyone know why...thnx!

you'll be needing forge internal soon men and a bigger turbo that can spool for that long.

No, you'll be falling out of the power band very fast at that RPM with those mods....

Whats the max boost you see? I have no doubt its been flashed but most tuners would want to hit 15+ psi with the td04 + turbo back. Maybe the intercooler was put on after the flash causing some fluctuations in the tune. Could be a number of things, not being completely sure about the mod history will make it alot harder to figure out whats what....

Tell you friend to find a reputable tuner soon. Also let him know to quit revving the crap out of his motor or it will not last.

the forged internals have zero to do with the 8krpm redline. Its the valvetrain that will be the problem. If it has the JDM heads on it, 9k isnt really even a problem.

I agree with having to upgrade the valvetrain, what about the stock crank? Can it handle that kind of RPM?

no problem whatsoever.


My buddy is revving his 02 WRX motor to 7500 and has been for a long time. This is even with the shim over bucket valvetrain. I know thats not 8k, but with the 04 style valvetrain, its been done with no issues.

Forged pistons would almost certainly make it easier on the crank bearings, due to less weight/stress, but it can spin 8k without it.

so if his computer is reflashed and my friend really wants a accessport, the fact that its already been reflashed, could that cause issues u think? i dont want him to **** his ECU up, u know? thats a expensive fix

I don't think it will be a problem if you get an accessport because you will just flash over the map that is already there. I think....?

7.5k and 8k are very very different.
Why do you think the JDM crank has the extra oil holes?
IMO a USDM short block will not last very long at 8K. You will get an OK lifespan at 7.5k, would last even longer with lighter internals.
