wtf?
1. run a biggert turbo to get a bit later boost = more traction on fwd
2. Honda motors like to flow much better than the sr20 etc etc so no matter what the turbo will come on boost earlier
3. More cp = less boost to reach a similar if not more power goal = less heat
bla bla bla.

for a stock b18c id look at a gt2871r built internals something up around a gt30 maybe 35 on the smaller side of the 35's. then there are other turbos too not just garrett.
