Ok im not a retard that wants to raise my revlimit. I have a 90 b18a and plan on running a large turbo with alot of lag. My question is that if i had cams and nothing else and kept making power past the 6900 fuel cut what is safe limits of the ls head? Sorry I know this isnt an allmotor question but I know you guys know alot more about headwork than turbo guys. Thanks.

 

stock valvetrain i say 7500 would be pushing float but hey who knows try it and tell us actually just be smart and get valvetrain with the cams and then go 7800 or 8200 and be happy just like all those ls vtec guys till you do blow up

 

I talked with a guy with a b18b w/ large turbo and he was telling me he reved his stock head to 7500 on the dyno every run. I was just wondering if that was actually safe and what others thought. Anyone else?

Im a noob when it comes to headwork, what is needed to safely raise the redline? Just springs and or valves? If not what else?

 

with my b18b i have reved till 8000 before, but usually 7500. I only have arp rod bolts.

 

wow. Does anyone know if there is any differences in the head between the b18a/b18b?

 

with my b18b head ive took it to 8k but of course i got the head worked on..p&p 3 angle valve job w/crower valvetrain..still made power and was safe everytime i took it for a pass..but this was an all motor setup..

 

yea i was wondering about the stock head tho.

mine was a stock head. the only difference between b18b and b18a head are the cams and intake manifold, and the differences are not big.

 

So i should be safe reving it to 7.5 with some arp bolts?
