in the what swap for my car sticky it has this info

pros
Great torque (133 ft/lbs)
good boost motors
inexpensive
B20z=146hp

Cons
Thin cylinder walls
Have to peice together a swap for a Civic (can't drop it in with a B20 tranny)
Won't pass BAR (light truck motor in a car)
Low hp in the B20b(126 hp)

but i have a few questions i have never worked with the b-series yet

1. which one has the thin cylinder walls

2. how much boost can i throw at it with out bein built, im not lookin for bad-azz horsepower but enough to move me around

3. can i use my stock 96 cx engine harness

im not a noob at hondas just the b series, so i came here for the answers

 

People are always going to say to sleeve the b20 because of it's "thin walls". Me personally have seen 3 b20's on boost that are still running fine n 10lbs of boost, stock bottom ends for 3 years now. I will try to contact him. 10lbs will be the most to push on the b20, daily driven i would do 8 lbs. Yes you can retain your 96 cx harness. Now about BAR testing and stuff of that sort, we don't have to deal with that down here in south florida. The main thing in boosting any type of motor, is to have good fuel management and a good tuner.

 

i dont have worries about tuning, i was planning on about 8lbs anyway, i live in oklahoma where there is no emisions, or any kind of inspection, but do both b20's have thin cylinder walls,

what is the difference in compression for b and the z

 

anyone

 

Yes, all B20's have thin cylinder walls.

2. i went 10-12 lbs all day long...tuned though
3. yes just add vtec

 

thanks,


i did however find the copression ratios, so i guess that is about it, unless someone knows any little extra bit that i should know

 

8 lbs should be good for you...nothing above that unless tuned...gl

 

will vtec make it that much of a difference, but i do have 2 d motors im trying to get rid of,

one a a stroked z6 built by rs machine,
and the other is a stock d15b

 

its a 96 cx it didnt have vtec, but i do have 2 d motors im trying to get rid of,

one a a stroked z6 built by rs machine,
and the other is a stock d15b

 

the cylinders crack because of detonation. have a good tune and dont try to push a ton of power on them and you should be fine.

 

so should i not use a b20 because of the cracking, i wanna just slap it in

use whatever you want...you have to make your own decision we cant tell you. every motor has potential to make power.

 

right i normally do make my own decisions, but i wanna know statistics, like how often do the cylinder walls crack, and is it the driver pushing it, or with normal drivin, overboosting? stuff like that, noone ever says yeah the (fill in the blank motor) is awesome, but dont do this cause that is how i cracked mine, its always the motors fault
