WHICH IS BETTER???

[lilkhm3r13oi]

i wanna boost my car but the thing is which would b better 2 boost a b20 with a gsr head or a ls with a gsr head??? which would b better

[NAG2I]

if you have both then b20

[mocha latte cupcake]

neither... both are hondas..... i mean why? lol lol i kid i kid i'm drunk and don't know hondas.. don't ask me lol

[patrick4588]

how about a straight ls

[nash8]

LSVtec

wow.... some useless info here.... I do know this , i would do the LS... The b20 has MUCH more thin sleeves.... Drop a set of forged piston's and rods in and your good to go for 400whp on a ls.. The sleeves in b20's will blow out a lot sooner tha a LS.. I also think the b18b head flows better , but dont quote me on that...

even with the forged internals, you will probably need some head work to reach 400whp. you can probably get it, but it will be A LOT easier with a good valve job and p&p. yes the b20 has thinner sleeves so the ls is better for boost. good post goinfasterthanu :goodjob:

if you are keeping stock internals use the b20 bottom end... if you are going forged pistons, rods etc i would use the ls bottom end if you aren't going to get it sleeved....

[Goinfasterthanu]

Thanks ... belive i learned all this in 2 weeks..? I was a h22 guy..... Yea head work would help a LOT as the ls/b20 head flows like ass.....for 400whp that is...

LS block with a GSR head.:goodjob: B20=weak cylinder sleeves. If you want a 2 liter than just resleeve the LS block to make it a 2 liter, 84.5mm or whatever. I heard that 83mm sleeves are more ideal for turbo, i dunno though.

[NAG2I]

hmm i didnt know b20 sleeves werent as strong as an ls
learn somethin new everyday i guess
but if thats the case then ya go ls

so best bet is 2 go wit a ls bottom end wit a gsr head damn i thought it woulda been better if i was 2 go with the b20 considering it had more torque than the ls but didin know about the sleevez but would it matter if im goin with a gsr head cause i do plan on upgradin the pistonz n etc.

Trader! H22 FTW!...lol i cant say anything though. I gave up on my h2b setup and bought a 240 :)

i would just boost the stock ls if i done ls vtec i would do all motor gl

[patrick4588]

gsr head and b16 head flow nearly identical in stock form.

I thought the point to do ls vtec is to have a stronger bottom end to turbo with vtec... Why not all alum. block and head to do all motor?

Wrong killa. gsr head flows more than the itr/b16 heads.

[Pickleteg]

I always thought that the B16/ITR head flowed better than the GSR head....maybe I am wrong.

[chituntang]

I thought that ITR head has some port job on them, which suppose to make it flows better too...

[patrick4588]

nope. in stock form, the b16 and gsr head flows within 2 cfm's of each other. alaniz did the test a few years ago. i used to have the chart. but 2 cfm's doesnt mean **** honestly. they are about the same. the gsr has slightly higher compression due to the smaller combustion chambers. the itr is a b16 head with a port job and will outflow either in stock form.

haha i still have to disagree with you. I've had them all. I know the differences. And i'll like to see you explain your idea to Ed @ Balance too.
