I heard that U could port the intake manifold on a B18A and get more HP than getting the B18B manifold and throttle body.. Help me out... True or myth????

 

I see people lookin but no help!!!!

 

u mean b18a ported vs. b18b stock, yes the A would give u better results

 

sweet thanks.... I have just always heard that a B18B manifold and throttle body would add 10 horses...

whoever told u that is a retard., or possibly misinformed, lol but no thats not true

 

I figured so... But U never know with hondas.... I was just told the main diff between the B and the A is the intake manifold thats where the 10 hp diff comes from

 

The main difference between a b18a and b18b is in the cams. then there is a small difference in the intake manifold, and i believe that is it.

 

Got these pics off G2IC. This particular "Euro" B20 manifold is the same as a B18B. Looks like quite the difference to me...


Notice the longer runners and larger plenum...


These intake ports correspond to the ports on the head. HUGE difference...

 

WoW quite a BIG difference... That s crazy... Well that answers my question... LoL Guess I either have a nice hunt ahead of me 2 find and intake manifold or a long time porting... loL

 

yeah huge difference in the intake ports alwayz wanted to see a comparison pic of the 2 manifolds.
also the tb on the b18a is 58mm and the b18b is 60mm
and the difference in the cams is like going from a sir1 cam to a gsr(sir2)cam. saw a nice dyno on it, gain of 6whp@ 6500 still no gain in low and mid but good top end,pretty nice considering you can find a pair for about 40 bucks.

 

I can find B cams but I can t find a B throttle body.... I wonder where they hide them... Does any1 know the lift and stuff of the B cams compared 2 the A's???

 

i have a b20b intake manifold with throttle body and a set of stock b18b1 cams. give me an offer
