ok... some of you may have read some of my olders posts... but i am wanting to get a b20 and keep it non-vtec and boost the **** outta it... im just trying to figure out for one which tranny to use... and 2 who makes low comp. pistons for it... as for the tranny i have heard that the LS tranny with the longer gearing is best for a turbo application... but then ive also been told screw the LS tranny go CTR or ITR... i want to know you guys opinions on this.. i want to get everything that i need figured out before i dive into this head first... as for the pistons... i need the lowest comp i can find i wanna run between 15-25lbs so i need the lowest comp.. and also who makes good STRONG rods for a B20... well any insight into the b20Turbo will be greatly appreciated

Check out www.crower.com they make good rods and valves...i've never heard any bad stuff about them...but i heard a few people say they didnt like the camshafts...thats what I'm using in b18c1 i'm building up...tell you how it goes in a few months when I get everything and have it running...

just get a GSR tranny with quaife.

 

since the b20's head is the LS head i can use all the valve train that is for the LS... correct.. like the crower turbo cams.. and the crower dual springs and retainers...
someone correct me if im wrong

 

another b20 question is can i use b18a/b pistons?? i have had a hard time finding b20 pistons?? JE makes soe but they are for the b20/vtec applications... endyn does make pistons for the b20 but the comp ratio isnt as low as i would like.

i suggest gsr tranny because it has the best overall gearing......not too long....not too short

any forged piston will work

eagle rods are cheap and effective

i hope you have good tuning and a standalone for pushing over 10 lbs

you may want to look into sleeving from golden eagle since the 700 job will save you a headache in the future

Yes, they basically share the same head. The only difference is the combustion chamber which is a little bit wider. So, any valvetrain meant for an LS will fit in a B20.

No. The only difference between a b20 and b18a/b is the bore of the cylinders. So, a 1.8l piston wouldn't work too well in that motor.

JE can custom make any piston you want. Tell them your application and what compression you want and they can make them for you. Should be like $500 for a set with rings.

 

get a gsr lsd tranny
