look on ebay man, i got a GM one for like 60 bucks i think
just got my 3 bar sensor :)
the map sensor you guys have is it generic or was it made to fit b series?
the one i got was off a b18c
just to get this back on track, here are a couple of comparisons-

as you can see the rear on the GT30 has a fair bit more flow than the GT28 having said that, the difference between the .64 and .86 on the 28 is quite big as well, maybe this would be enough?

Personally, I wouldnt get the GT3071R with a T28 style exhaust housing, it is more efficient with the .63 T3 housing
agreed ^^^^
The T28 flange adds too much restriction on the GT3s
what do you guys think would spool faster,
gt2871r with .82 t3 housing
or gt3076r with .63 ar t3 housing
this on a b16a2 with ~8.6:1 CR
i ask this because i went from .63 t3 -> .82 t3 on my gt2871r and it gains full boost over 1000 rpm later now. was around 4250, but now it seems 5500 or even a little later, i wonder if the housing is just too big for the turbine.
although my powe rband now is much more meaty, i wonder if a gt3076r would net me similar spool, but more power from a better efficency part of the compressor map + later choking point from the turbine outlet.
this is for 20psi on pump fuel btw
hard to say cos i've never seen the .82 rear on the gt2871r.
I know on my gt2871r T28 with .86 rear , it starts to spool at about 2,300k, then hits 10PSI at about 4,500k.
Haven't seen a gt3076 on a b16, but it would be at least another 500rpm later
Judging by my compression and a 8.6 i'd say it would take another 250 to 500rpm more to spool up + 500 or so to boost to 20PSI. Once you get about 6PSI the boost will jump very fast.
that's my best guess
with the 30 you would get full boost by about 5000rpm or a touch later but would hit a lot harder once on boost :)
