okay so i'v done a bit of research, and i found the c-speed racing compr. calc and it said that i'l get a comp ratio of 10.8:1 using b16a pistons in a stockass b18b engine.....

so i was just wondering, to the ppl who'v done this, with a jump in compression of 1.6:1 (coz b18b is 9.2:1), what gains would i get with the rest of the engine being stockstandard inside, and the only other mods being i/h/e????

none of the other threads i saw covered the type of power increase one would achieve by doing this......

thanks in advance

oh, forgot to say this, im guessing i'd have to get the ecu chipped and tuned to sort out the fuelling if i raise the cr so much??

also, will a cr of 10.8 be ok to run off pump gas, we get 95 octane from the pumps in South Africa..

thanks guys

would like to know also...

 

**** i jus got a quote on those pistons from my honda dealer... they the equivalent of $460... someone tell me if the power increase be worth the bucks???

thanks bud!! i was looking at SI pistons (B16A) coz thats the only VTEC engine available in SOuth Africa.. im gonna check out hmotorsonline for sure, thanks for the help man

 

CTR pistons pops cr up to 11.4-1 according to the c-speed racing compression calculator .

is that still gonna be ok to run with 95 octane pump gas?? and otherwise stock internals?
