I'm putting together an LS/VTEC right now.

It is a 1990 B18A1 block, and it has:

81mm B16A PR3 pistons with new rings
Stock LS rods (balanced, with ARP Rod bolts, and also remachined after the bolts were installed)
B16A oil pump, water pump
Balanced Crankshaft, flywheel/pressure plate and crank pulley
New ACL bearings
ARP head studs (not sure how much this will help)

What would be the RPM limit on this block? I was thinking in the 8400 RPM range or so. I heard that the PR3 pistons are the lightest stock B series pistons out there. I'm sure the ARP rod bolts will help quite a bit in terms of reliability.

Thoughts?

 

Whatever rpm you stop making power on the dyno, thats the max rpm. if you get 10 people reply to your question your going to get 10 different answers. I take my LS/VTEC past 9K often. I'm never had a problem. whatever the dyno tells you thats what I would stick with. just my.02

Thanks man. I'm not too concerned at the moment, probably because I'm only going to be running some JDM P30 cams (for now). However, when I get some better valvetrain, I'll likely have to shift pretty high with that compression to make some good power. Hence my question

 

drag engine or street?
