dont know what route to take.

i need to either rebuilt my b18 gsr engine (block/head) or thinking about getting a b20 engine in my teg.

had turbo on my b18 then got engine knock. i bought stock pistons/rods all the neccessary gaskets and pumps b4 i thought about the b20 swap.

my ? is would it be better to just continue with my gsr engine and just hone the block and fix my head or just buy a b20 engine for $500.00 and call it a day. will also turbo the b20.

trying to get the best bang for the buck.

 

I would spend the money building a good turbo motor.
What if the b20 start knocking after couple hundred miles?
I never like running turbo with stock engines.
is just me!!

 

b20 with vtec head and turbo.

Depending which B20 block it is you should have lower compression aswell.

B20A - No go doesnt work.
B20B 9:1
B20Z 9.8:1

Thats with stock rods,pistons and vtec head.

IMO its always best to have the most capacity you can get for hondas.

 

Keep your GSR motor, if you're not willing to build the B20 right, might as well not do it, since you might just end up with problems in the future.

 

You bought stock pistons on a turbocharged high-compression engine? I hope you had an excellent tune or that might explain your engine knock.

GSR is a better built motor; if you want more low-end power there's a few stroker kits on the market that'll give you what you need, and since they come with low compression pistons and stronger rods you're all set for forced induction.

Plus, even if you keep the GSR head the B20 block doesn't have those fancy oil squirters, and I've heard too many horror stories about CRVtec hybrids.

Just stick with the GSR.

 

IMO build the GSR. b20 are torquey but the have thin cylinder walls. if you boost to much you will crack them walls.

 

x2! stick with the gsr

 

Agreed.

 

B20...

 

i know someone that has a b20 that is boosted with a good tune, yea its fast, but in th past year he has been through 3 blocks.

 

do as you wish...stock b20 turbos are the same as turboin an ls...know your limits and do things right the first time

 

I would go B20 turbo... torquey, cheap motor, lots of power with a good tune. I built a 12.0:1 LS VTEC and I wish I had gone B20 boost... but that's just me.

 

build the gsr. with the 500 you can rebuild the gsr and make more power than the b20.

besides, you dont know the condition of the b20. what if the walls crack within 1000miles or less? Rebuilding hte gsr will also give reassurance.

 

no, turboing a b20 is worse than turboing an ls motor because the b20 has thinner cylinder walls.

 

true story. i would rather boost an ls over a b20.

 

I have a b20, and I'm actually swapping over to a GSR! The B20 is a good motor, but deffinately not a choice for boost. The cylinder walls are way too thin. Now thats not to say that its not capable of being turbo, b/c a friend of mine is boosting about 21 psi into one. But they really need to be sleeved and built at least mildly. If all you wanna do is boost get a b18b, the LS motor. They are the same price and are much more responsive to boost. But as far as you b20 goes, you could make a nastly b20/vtec!

 

its called knowing your limits...guy with a stock b20 turbo eg hatch here ran low 12's all day....and i've known guys who rev stock b20 bottoms with vtec heads to 8500rpm all day...i guess some people are just luckier than others

 

x2

 

well he might not get as lucky. 8500 on a stock b20 bottom end "all day" is pretty intense. His tune must've been really good.

 

Keep your GSR motor. Besides that's what Acura meant the TEG to have not a B20.
It's your choice. If I ever need to rebuild mine I'm keeping my B18C1

 

ahaha GOOD TUNE is the way to go

 

x3!
