I am thinking about using the b20 block with b18 head. I have the greddy turbo kit also..Now as far as the block girdle goes, is it really necassary?I heard that I will not be able to rev as high with out it because the crank isnt balanced well..Now, what other things are important when doing this?? I know you have to run the oil lines but are there any other modifications that i will have to do to make this all work??Basicly Im looking for answers from some people that have done this and no what can be a PITA when running this set up..
TIA

No a girdle is not necessary. I don't have one, and haven't had one for over a year now. I rev high too. Now as far as oil lines are you going turbo or what?

 

Yes..Im definetly throwing my turbo back on. Now I heard that you can rev it high but not as high as a normal b18 block..I wish actually that ther was a way to use the block girdle from my b18 block because from what it looks like it comes stock with one..hehe decisions decisions
thanks

thanks guys

Are you confusing the windage tray for a block girdle?

 

I sell theses all the time you have to plug the oil hole in the block. The reason why these motors don't rev high in the first place would be a poor oiling system when compared to vtec Oil systems..

 

help me out
im trying to decide between the b18b and b20b/z, boosting if i get either one. Now my question is the b20 worth spending the extra $400 or should i just go w the ls and use that extra money on the turbo? what do you think, i cant decide.
How much of a difference would the b20 feel over the b18? thnks in advance everyone.
