Alright, i know the b18b from the newer generation tegs is a good canidate for a ls/vtec turbo, but at the moment i have the oppurtunity to pick up a b18a1 block from an older teg 90-93 to be exact for really cheap. This motor has been semi rebuilt w/ new thrust and crank bearings, and rod bearings. It also has been checked over by a machine shop to meet the specs and cleaned up...Would this be a bad investment towards my ls/vtec turbo setup. What i really want to know is what are the major changes in the b18b shortblock and the b18a1 shortblock if there are any?

 

the b18b1 and b18a1 have the exact same shortblock, no differences. the newer 96 plus b18b1 have different pcv system though

 

so if i was to slap a b18c1 head on top i wouldnt run into any ohter problems besides the standard ls/vtec shiznit..correct? The head by the way is from a 94 gsr if that matters at all about the whole pcv system.

set up the same as ls/vtec with a b18b

 

the only significant difference is the B18B has Knock Sensor
B18A doesnt have it
