push a small snail and they make a lot of heat, and that 15g may fall out of max boost up top..its safer to buy a bigger turbo...dont know about the downpipe

15 psi is fine. but trust me u will be bored with the lil 250whp that it pushes out. ur power will die up top. looking into something bigger like a t3/to4b, t3/to4e 50 trim while the block is in the shopa\
