sr20det redline at 7200rpm or 8200rpm?

[CrazyAsianBoi]

I don't know who is right but I was told that the SR engine redline is at 7200rpm. But when I bought my engine, the guy that I bought it from told me 8200rpm. Who's right?

If you have a stock valvetrain 7200 is the limit. Well technically 7500. I wouldn't rev to either without RAS, valvesprings, retainers, and solid pivots. 8200 = a demolished head.

[Sil80sushi]

not the guy that said 8200

[nismofamily]

8200RPM=BOOM

[jdm180]

i agree 8200 is rediculous unless your engine is completely built. i would stick to around 7000 on a stock engine.

i set mine to 6800 with a bee r rev limiter. not a damn problem and plenty of powa!

[sx_hatch]

7600 is stock rev limit

[Onizuka]

I used to rev it till 7500 all the time with just rocker arm stoppers while autocrossing and never had any problems. I've revved past that a few times and never broke a rocker arm. I really dont care if I do, rocker arm stoppers can be had for cheap. The head is no where near as fragile as people make it out to be.

would RAS's be good to do even on a completly stock redtop?

Whats a rev limit?

[redtop91]

^ LOL grammar Nazi. Dude you have to tell me how to use the Turbo Timer. It's hooked up but only beeps when I turn the car on and off, doesn't keep it on after I remove the key. I probably just dunno how to use it

[ILikeMy240sx]

if you hook up the wire to the tach, you can set it to do an auto countdown. If not, you can manually select it to do 30 seconds, 1 minute, etc etc.

Go to the HKS website and you can get the english manual.

well Im not being a grammar Nazi... My car doesnt know what a rev limit is haha.

Ok . And you never posted vids of the ungodly revving abilities of your car. You owe us video.

RAS are so cheap there is no reason not to do it.

All rocker arm stoppers regardless of brand are the same right? Tomie, greddy, etc/

i THINK tomei and phase2's are the only ones that are stainless.

[Onizuka]

They will have a coating of oil the whole time so stainless doesn't matter much either. I'd just go with whats cheapest. I bought an HKS set when they were on sale for cheap.
