thats big help :P

were the ---- is JD when you need him
need to know before Wednesday after noon

 

Shin Dig....Use this Guy's Turbo below

 

2nd one.

 

get a ching chong meow meow t3/t04e and try it out (as they are cheap)
and see where your making boost but it all depends on howmuch boost you want to run
my xj650 makes full boost at 10,500rpm (15psi) but it makes 5psi as low as 3500rpm
and 8psi arround 4600-4800rpm

and if i wanted to run like 30psi i would need to rev to arround 18000rpm (i have my wg fully closed so it just keeps making more boost until the revs drop, it's a tiny turbo so it dosen't spool up to much air)

 

want to specify
or is that a guess
