For the most part yes, but when you look at dynos you see that many people running t3/t04's still have pretty good low end. As far as the B18b head flowing better, Im sure it flows better, but really not that much better.

wrong.
some hondas are capable of revving to 9, most are not.
the B18B from the LS integra is very similar to the mazda BP in power output, power band, rod ratio, etc. It limited to about 7500 rpm on the stock bottom end.
people still run 30r and even 35r turbos on them.
the miata community is phobic of large turbos, there is no denying it.

Wow, shouldn't have brought up the Honda =\ Anyways, I just got home from the local miata shop and the head dude happened to have a 1.6 head that he's been working. There's quite a bit of metal missing from the intake and exhaust ports compared to a stock 1.6. Should help with spool and power, regardless of turbo choice.
Considering the way I drive, wanting to make sure I don't drop out of boost between shifts, and wanting the ability of 300hp, the gt28rs is probably going to get the nod.
Thanks for the help!

Lack of absurd flow with my bagi cast mani and bell mouth 2.5" dp
I'm pretty happy with how the turbo is performing, going from 16 psi to 22 with meth made a HUGE difference according to my butt dyno and the fact that I can spin tire thru 2nd gear.
I was going to be happy with 280/250 but you now have my expectations up.

The question i have: what would your numbers translate to a .20 over 1.8 with similar manifold and exhaust. if i can only get to 300hp i'll be disappointed. since i have put so much money into this motor. I'd want to put a bigger turbo on, but like brain said; late spool will start to kill fun. What are the specs on the 3071?. If spelling sucks i apologize. i cant see what i'm typing because my phone keyboard is in the way. F***ing awsome levnubin!. Give that dyno hell. i'm counting on you to put up big numbers.j

Are you using 2554 as per your sig? Stock IM? Really expect 300 from that setup? You and I seem to be on the same track, time-wise, on our builds. I should have my built .5mm (.020) overbored 1.8/'00 head back in like 2 weeks. I'm on 2560, no port work, stock IM, tubular ex mani. I'll be fueling with E85. If I get 300 I will probably suck my own ****. Maybe I am wrong-headed in sticking with the tiny turbo, but I am looking for instatorque from <3000 pulling second gear out of turn-around cones.
