real world experience talking here.
my best friend has a turbo h22a delsol. we built it from a beat shell last winter. hes currently running 8 psi off a t3/4e 60 trim.
and honeslty, it sucks. he has recently been beatin by a turbo cavalier i put together for a kid named pete. cavy was on 10 psi out of a 48/60 and it reamed him.
pissedoffsol has prob seen the cavy and the del sol floating around.
unless your gonna build the block, an h22a boosted is not a good choice imo.
brian may say different, and its all about the tune yada yada, bottom line is the frm sleeves suck, and the pistons are brittle. even with a good tune and conservative timing, itll blow eventually.
