I was wondering if anyone knows about how much a stock type r bottom end can take? I plan on getting ITR or CTR cams and a P&P as well as the usual bolt-ons and necessary tuning gear with plenty of quality time spent on a dyno. Reliability is a primary concern. Any help is greatly appreciated, thanks in advance.

 

What do you mean by how much it can take? If you are referring to HP and torque, I made 194.4hp and 129.6 ft-lbs on a stock bottom end. The power was in the bolt ons and the cams.
Was that what you were looking for?

Sort of what I am looking for. I guess a better way to ask would be: how much power can a stock ITR bottom end take and still retain good reliability? No I do not constantly rev the **** out of my car and yes I do my own maintenance and am **** about it. The car would be a daily driver/autoxer.

Also, would 11.1:1 or there about be too high compression to run on 91 octane at 7220' elevation (no I am not one of those people who skimps and puts 91 in, thats all we get up here)? Thanks in advance for any help.

BTW-FSTASNTZ, what cams/boltons were you using to achive those figures? Thanks.

 

Well NA the bottom end is nearly indestructable if you do the proper maintanance and never let it over heat, the rings will be the first to go, rarely will a C5 bottom end squeek a bearing or throw a rod, this usually only happens on frek lemon motors or motors that are being pushed for extended amounts of time while under enormous strain (Examples include hill climbing, Towing a boat, fully loaded with 4 400 pound + fatties)

LOOLL!!! +Fatties!!! LOOOOOOOOOOOOOOLLLLLL OMG THAT WAS funny. whew.

 

stock bottom end should be able to hold 250hp for quite some time.
