Huh, cool idea. How about P8R information as well? I'll dig up some of the more pertinent threads later on and link them, if that's how we're going to be doing it.
All of those are great! Lets try to get as much info possible on LS 1.8L block and head. Hmm maybe a budget builders NONvtec (OEM, to whatever extent) build?
How bout RPM limits for LS Rods? RPM limits for LS Rods w/ ARP Bolts? etc etc. How high (Power and RPM) will our Non-VTEC heads keep flowing as compared to superior VTEC head flow characteristics?

All these ideas are golden, but lets get a steam of valid info to do the write up
B18B motor Benson sleeved to 85mm. Wiseco 11.5:1 pistons-IB rods. LS crank knife edged and balanced by Castillo's Crankshaft, teflon coated by IB. IB ported LS head (P75). Stock valves, JG springs and retainers. Crower 405A cams. JDM ITR header, no cat, stock ITR cat back, GSR muffler. Blox intake manifold, custom velocity stack intake. Precision 440 cc injectors. Hondata S300.
Took out the 405A's, installed a set of Brian Crower stage 2 cams, installed a GSR intake manifold custom fabricated to work on an LS head, motor makes 160/192 with a nice flat torque curve and my daughter drives the car everyday
So whats the verdict on the p8r and the ls 81mm block?

the combustion chamber on a p8r head is more like a b16 head as far as the chamber height and since it has a rather large volume (47cc) milling it isnt a bad idea. by this i mean the depth from the head surface to the quenchpad. i milled mine .024" and there was still room to go. in one of the other threads they suggested milling it down to the quench pads so you can run it on a 81mm block. this essentially would eliminate the pockets that would form if you installed this head on a smaller than 84mm block. i dont know one way or the other since i run a b20 block.
heres my chamber after milling .024, i suppose going .03-.04 would get you completely flat (i think i remember measureing the depth at .03" before it was milled)
How bout RPM limits for LS Rods? RPM limits for LS Rods w/ ARP Bolts? etc etc. How high (Power and RPM) will our Non-VTEC heads keep flowing as compared to superior VTEC head flow characteristics?
the limmiting factor on a LS build will almost always be the head. LS rods with ARP rod bolts are used pretty commonly on alot of motors here vtec and non vtec.. quite simply that combo will outrev your head.
the main thing that holds back our builds is camshaft size. take a loot at the vtec lobe size on some of the hotter vtec cams, skunk2 stage 2 or pro 1/2 BC spec 5 thes eall make good power up top. they also have alot more lift/duration than any cam we can run in a LS head. the crower 405a's are as big as you can go without having to modify the head and will support ~ 200whp.
i have ran my car only a few times this year and it has been really confusing. in the beginning of the year i ran a 14.77 @93 best pass. me and a old friend played with the ecu on his laptop(i didnt ask any questions about the tuning program he just wanted to try it out so i voluteered!) after the tune it ran a 14.26 @96 !! well that ecu burned up a resistor and started running like garbage! it started run 14.7's again. just thought i would share my experience on the non-vtec thread!!!!
how much do cams usually go for, i got a b20B stock with the factory PHK pistons, just curious at what the cams will do for me if im going to keep stock internals on the bottom end...

So far on this thread, members have mentions Crower 405A cams as well as B. Crower stage II

Incorrect. 405s need more compression than what the PHK pistons will provide. 403s will be nice, 404s will be ok. The BC0022s will be somewhat in the middle of those two, I'd expect.
Edit: For prices, figure ~$300 for cams (little less or a little more), and ~$300-350 for valvesprings and retainers, if you choose to use them.
