I have a chipped pr4 ecu that has a 9500 rpm limit. my b18a1 has crower dual valve springs and t-retainers, ferera valves, and stock rods with arp bolts. whats the max rpm b18a1 rods can handle with arp bolts?

If I had that setup, I wouldn't take it over 7500-7800 rpms depending on your powerband.

 

just because of the rods? i know the head can take the abuse and so can the pistons and crank. oem crank and je pistons.

 

mm i dont think there is a cam that will make power up that high in a non vtec motor...
the question is more like where do my cams drop off?

 

so dyno it and see were my power starts dropping off?

As far as the rev limit goes, you will get a lot of different opinions. From personal expierence, 8500 is good if you have ARP rod bolts, Tri-metal rodbearings and a VTEC oil pump.

I'd go to 9000 with a balanced rotating assembly.

But, like mmuller said, It would be useless to rev high if you're not making power there.

I have all those mods done, this is going to be a turboed engine im getting crower turbo cams when i get the turbo.

 

Because of the rocker design they often have problems over 8500 rpm.

 

im going 82 8500rpm thanks guys
