looking at the FP web site and found this
 

Was looking for a new turbo and i was on the Foced Performance web site and found this. I wanted to know if any one has used this turbo or see this turbo before looks like it might be good on a miata.

Forced Performance Turbochargers: Nissan SR20 20G Turbocharger

From an entirely noob perspective I imagine that is a massive turbo. Just based on the fact it is "an enormous increase in flow over the Big28" and the big 28 is a big increase over their T28 kit. Maximum street performance on a 2.0-2.5 liter car too.

I'm going to say this might eat your 1.6

The 8cm turbine housing would kill spool on a 1.6 or 1.8. It's a very good street turbo for the Suby 2.5. A bit laggy on the 2.0.

well never used that 20g but I did have an older FP 20g for my DSM.

Based on how the spool was on the 2.0, I won't want it on anything but a 1.9 or 2.0L miata. The spool is going to hurt, but it will make some nasty power :)

The hot side flows 8cm2 wich is like an evo 8 turbo but with a 20g hot side i am planning on running 20 to 25 psi i have a built motor now with 9:1 comp ported polished head and the car is a 99 so its the higher flowing heads and the motor ia a 1.9 with the over bore. im going to run a 8k redline or a 8.5k redline.
