Then internals youll want these
Crower Rods Stock length
and your choice of pistons weisco, endyn whoever you want bore is up to you ! Stock is ok but ihgh boost youll want sleeves or some sort of block guard like STR's
But if you want larger bore ad stroger block B20 with a closed deck is better and also you use LS rods BUT use B20 Pistons and i think wesico makes the VTEC version.
Clevitte or Top line bearings !
Then you have to get a VTEC head Preferably Type R or B16 B16 is closer to Type R than the GSR is !! But all will work none the less. after thats all done you can handle like 15-19 psi easy !! but build the head if you dont want your head to fall apart at like 9k rpm !! it depends on your wallet how fast your motor will be and how long it will last !! If you need parts i have shit everywhere let me know !!
Where can I start... *shakes head*
Im not too savvy on LS/VTEC's PM KJ on this. However, I believe KJ suggested GSR sized forged internals for the LS block, IE GSR crank, Forged GSR (Arias or wiseco are my favorite)pistons/(eagle will do fine)rods. I believe this keeps the R/S ratio at a great point for higher revving.
Block guard is a horrible idea, stick with a sleeved block and if you really want, go partial closed deck from GEM.
The B20 does have a larger bore, but effectivly it has a thinner sleeve because of this. it also does NOT have a closed deck. LS and B20 rods are the same IIRC. an LS block sleeved and bored to 84mm(2 litre) is the same thickness as a B20 sleeved would be, so there's really no difference. B20 and LS cranks are also the same.
VTEC version?
*sigh*
Stick to a stock redline of whatever head you purchase, depending on if your keeping it stock or not, just so you don't start to float a valve or anything unholy like that.
Of course the ITR head is better, but much too pricey IMHO, B16 heads are cheap because you can find older ones. GSR is my preference. Rev's higher stock also.
Once sleeved GEM says you could run 30+psi on them, provided your internals and tuning allow such a high boost pressure.
Anyone with knowledge please feel free to make corrections or additions.
