I was just wondering if anyone had run p73's in their ls/vtec setup and if they had any problems with them, i have p30's right now but im lookin for a little more compression...im running an all oem bottom end with arp rod bolts and p30's right now with a p&p gsr head with full ITR valve train and cams. Any thoughts???

 

nope, never been done by anyone on HT. you would be the first in 4 million engine builds to ever accomplish such a feat. you should try it and revolutionize the industry as we know it.
its apparent you have no idea what your talking about and should utizie the red words on the upper right hand side of your screen.

 

Don't JDM P73s only bump like .1 more than P30s?

 

The P73's will drop your compression .2-.3 compared to the P30's.

USDMs yeah, not JDM. check zeal. every combo of head to block the JDM P73s will be .1 more. The c-speed calculator is weird.

 

In response to (1 2 NV)...expletive you, thats why i hate HT most of the people on here are too good to help anyone. The question wasnt IF someone had ever done it but just to get some feed back on people experiences with them...these sites are here for a reason expletive!!!And yes i know how to use search...already did, just looking for some 1st hand answers not old and out dated ones...

Yes, it should be obvious to everyone that the compression ratio when running P73-00's changes by the day of the week, current timezone and moon phase, and one must compensate for this divide-by-zero time vortex in ones equations.

 

I heard about a guy doing it once, and said the "butt dyno" did not show a big improvement. But that was awhile ago, I am sure if he did it now his results would be different.

LOL HAHAHAHAHAHA. yeah by todays standards compared to threads started months ago the results have changed so much. good job, you proved my point without a doubt.
