my lag is your courtesy head start


ATTENTION.... installing a head gasket, head studs or pistons and rods in your otherwise STOCK engine dose not make it a "built" engine! stop listing you cars for sale saying they are built when its not!!

B20b are slightly better than the b18a.

Actually if you really want to get into the research aspect even brian crower has the wrong specs up for the cams. I have pulled apart 3 different b18b1 heads, 2 b18a1 head, and 1 b20b head. All had different combinations of cams. The markings were different on all cam shafts (except sometimes the intake cam was the same between the b18 motors)

it could be, but theres really no point in changing them!
go with stage 2 brian crower turbo cams!

now if you wanna take your motor to 10k go with stage 3 brian crower n/a cams on your turbo setup with dual stainless valve springs/retainers, ferrera stainless flat valves, and your good to go!
been there done that! ^ my current set up!

b20b are a tad more aggressive...maybe the difference of 1 or 2 whp on dyno...nothing noticeable.
