what up again h-t members. contemplating about going b20 block with gsr head. all stock internals for now. should i even go this route??? or should i just put back in a b18c1 block??? oh yeah...i have a dc2. thanks.

 

if u have a dc2 then u shoudl already have a gsr motor.

 

well i do but the block was shot(not my fault, previous owner). so in the mean time i have a b16a block with p73 pistons combined with my b18c1 head. runs pretty good....but that's just to get me by.

 

depends on what you want to do...

B20 = nice good torque.

but if hyou already have a gsr block, jsut rebuild it and use that, much simpler, and still very nice IMO...

well it's more complicated than a rebuild. 5 outta the 10 holes that the 10 head bolts go to have been stripped due to over reving at under 500 miles. so that seems like too many to try to heli-coil or even try to fix. i've tried some shops and they say that's way too many stripped as well.

 

rebuild the b16 block with a gsr crank, gsr rods and b16 pistons. that woudl be dope.. sleeper in a way too

 

B20 Block with GSR crank and rods.

 

B20
good = more torque
bad = not smog legal

 

i'm not worried about the smog part. i'm just worried about the reliability. i've seen quite a few threads about they're b20 vtecs not lasting.

 

the b20 would be good in that it will provide that much needed torque. however that block was never intended to rev to 8 grand constantly. so you would have to stenghten the block. get arp rod bolts and possibly some stronger rods. you can have a reliable b20/vtec if you spend the money and do it right the fisrt time.

 

i c. good input.

 

also bad: thin cylinder walls compared to other b series

 

aahhh....maybe i should just go back or to ls vtec.

maybe you should just rebuild your gsr block. imo, any ls/vtec or b20/vtec conversion requires more money for it to work and work reliably. it all depends on your pockets.

 

b20z... Mad Torque...

The walls are weaker wich could lead to sooner detenation. It is suggested that you resleave case. If that were you case and you put on a Vtec head... you would have a insane fast N/A car.

B20z/b16a is a total badass motor. Just be sure to do it right the first time. Dont cut cornors...

 

well i'm not planning on racing it or n e thing. i just wanna have more grunt when i need it. so far i've been pretty impressed with the b16a block i have as a temporary motor. how hard would it be to upgrade the b16a block i have? for instance with a gsr crank, either aftermarket rods and pistons or p73 pistons, can i go with b16 rods and pistons with a gsr crank? or is there n e oem combo that'll work on the b16a block? if the b20 block is left stock as well as the head for daily driving purposes, will i still be at risk? the only thing i ever do is occasionally i go to the famoso raceway and test my car. like maybe 2-3 times a year only.

 

I believe the b20 is only at risk under high boost, and when you bore it out. I mean if it wasnt built to last honda wouldn't have made it....

If you want to up-grade your pistons I would go with the pr3. It will raise your compression a little over the p73 A0.

I don't know much about the cranks but I have been lead to believe that thoughout the B-series motors they are all pretty strong.

Want more umph.... B16a Block, Stock Crank, Eagle Rods, pr3 pistons (block)
B16a Head, pretty much stock.
High End Power, 4-1 Header, Upgraded Intake Manifold.
Whatever you decide to do be sure to get it tuned. And with that setup you should be able to run it to 9k rpm.

Its cool that you dont cant about going fast. If that was the case.... The only fast honda out there is a bike!

 

well in my car i have the b16a block, b18c1 head, p73 pistons....like i said before as a temporary motor. i can't rebuild the b18c1 block...too many holes stripped(not my fault, i feel so bad for the block!). i mean the motor set up right now feels pretty darn good. not as good as my buddies itr or gsr...but pretty close to the gsr. and i know the saying "there's no replacement for displacement", and that keeps me intrigued with the b20, since my b18c1 block is done for. all in all i just really wanna be safe. i don't feel like boreing out my block to like 84mm or whatever....i mean if i can get the b16a block set up to "getty-up" with out radically changing internals then i might just stay with it.

and if i'm still not happy with the b20 or upgraded b16a or b18b or b18c1 or b18c5 then look out honda cbr...here i come!!! lol...
