B20b Block w/gsr head

10-30-2005, 12:18 PM
Right now i have a blown b18c1 block and i'm thinking bout buying a b20b block and using it with my b18c1 head. Will this combo work and is it a good idea to do and would i get better numbers putting a turbo or going n/a. I race my car at da tracks every so often but i really don't know all the ins and outs on how to go about it. Is there anyone out there that can help me out with some advice. Thanks a lot

did you destroy the block or what the hell did you do?

yeah, i blew da motor. I was burning oil but have not found that reason yet. I will be taking da motor out soon but i was thinking about getting a b20b block and doing that with a turbo instead of rebuildig my motor and making that turbo but i wanted to if it would be a good idea to do that with my gsr and if the numbers would be worth it. i need some suggestions on this. thanks

a gsr motor is much better for boost than a B20..... how did you blow the motor? What is wrong w/ it, because if the GSR engine is salvageable, that'd be my choice!!

and as far as boost..... read

compression and leakdown to isolate the problem on the b18c. if the head is salvagable, buy a new b18c shortblock and put the old head on the new.

see....the B20 is not the better of the two! B18C1>B20

did you punch a hole in the block....crack it in half....or what? It should be salvageable unless you really kicked the crap out of it!

it sounds like rod knock. Everytime i rev it up it sounds like a loud rattling noise in the block

spun a crank bearing.....that doesn't mean you have to replace the block......

it would probably be a rod not a crank bearing

have someone look at it before you go and spend money on a new block and time on putting it all together...
