trying to decide which motor to start a build up for my gsr head. the engine will be sleeved, girdled, and of course all the other motor building parts required for high boost application. The only difference i can find between the b20b/z and the b18b is the bore. Stroke is the same. anybody correct me if i am misinformed. Where should i look for either or engine??


BTW- stupid me just traded a b16a block for my b18b block!!!! thought i wanted to do something i decided not to do. anybody need a b16 block????

Like the old saying. "There is no replacement for displacement."
Simply put.
Although, since your getting the block sleeved, you can easily get the 1.8 up to 2.0.

 

So is there any difference in the block besides bore????
Are the cylinder walls thicker in the b20?
Would a b18 bored to a 2.0 be exactly the same as an untouched b20??
