i have a b18b1 ls/vtec motor with pr3 pistons arp rod bolts and head studs....i/e/h im running a b16 head with itr intake manifold and throttle body and ctr cams...

im just wondering what my compression is because i checked all the comrpession calculators and they gave me different results

thanks

 

What head? stock valves? was your head milled or your block decked? how many layers are in your headgasket? many factors change compression

11.2 with b16 head and 11.5 with gsr heads

Everything you need. The reason why this one might be different (or more accurate IMO) is because unlike the c-speed or ff-squad calculators, this one also includes head milling and rod length.

11.94:1 according to the link

thanks man for the info but will i make good power on 91 octane with 11.9 cp on a vafc until i switch over to obd-1 and a chipped p28 ecu and hondata?

 

VAFCs suck. That said, they were a benchmark in their day, and worked. You'll be fine with it but for "real" tunability, chipped ECU is the way to go.

 

if the head/block is not milled and your runing stock valves.
compression with 81mm pr3's with a b16 head should be 11.3 and 11.5 with a gsr head

ok i got b18a block decked to like about 8 mills,gsr head shaved to 10 mills ,omni flat valves, block over sized to .20, ctr pistons , s2s3 cams, 70mm tb,pnp head. the only thing that im not sure about is the bearings they are clevete 77. but all the rest its ok.how much compresion and how much power should i be making. by the way its mated to a b16 cable trany with the diff. welded in a 89 crx and a chiped p28. havent gotten tuned yet , just waiting on wilson from puerto rico to tune and harold to degree my cams.any info would be great...

 

might want to make your own thread ^ your compression is pretty high especially with a decked head probably 13-1 +

 

im hopein to be keepin up wit srt-4 and cars like that

 

my pr3 lsvtec was 11.7:1

the only way your goign to krrp up with srt4's is if you go boost or if this motor is droped in some gutted sub 2000 pound tim can crx or civic

No, my man. No.

Quit shitting on everyone's parade. Simply because YOUR particular all motor setup didn't produce the numbers you wanted, doesn't mean everyone's build will be the same. Go troll around in the Forced Induction forum, where someone might give a ****.

My car weighs 2600+lbs, I run 13.1's trapping 104-105mph.

Gutted, sub-2000lb. CRX? I think not.

SRT-4's are no problem.

thats true, its your build. i own a 91 da that runs 13.46@97mph all motor, nonvtec and has spanked ls vtecs with nitrous and im sure i'll spank an srt....
