right will be building a b18 start of the new year, been reading up bout gt35-40 turbo's, but people say run the bw s366 and the s372, would want to be around the 700whp mark, so when would you be on good boost on the BW turbo's

The s372 is about the same as a gt42. so they are huge. and not something you would want on a street driven car.

yeah i did notice it's fairly large , but when does it hit say 25psi?

well depends on the full set up. but i'm sure it will take a while for it to first start building boost, probably all of first gear, then probably spool fairly quickly like most turbos. once ya get em going they just keep going and going. a gt35 can make 700hp, and would have a lot quicker spool time.

but with the gt turbo's when they blow up they cost alot to rebuild due to new core's, and have heard the s366 spools the same as the 35 but power power

But how often have you heard of a gt turbo blowing up? I know probably 15-20 people, if not more, using gt turbo's, and none of them have ever had a problem.
