im running a master power t70. its a little bigger mm inlet then the t78. its laggy... but i can live with it.
I would like a .84 hot side tho. im running a 1.0 now and it adds to the lag.

spacerat (jared) is running a t4/61
-GT35R 61mm compressor wheel
-0.70AR T04S compressor housing
- Flow Rate 65lb/min
.96 AR turbine housing
he dynoed at 401 on race gas (20 psi). he ran a 12.012 with radials and 12.5 is his best with street tires i believe (on race gas). he also uses alcohol injection and a nice vmount
as soon as i find a haltech im going to be running a T4/67 with a .96 housing. which is a 75 lb/min turbo and im hoping for 450-500 with meth injection and a npr intercooler.
this is all on stock ports btw

and my understand is that the turbo lag is really not all that bad compared to his hybrid he was running before. i also heard he gets 20 mpg around town . i dunno how true that one is but its cool.
but what you need to remember is that porting does not open up the ports (more flow) as much as it changes the "cam profile" of the engine.

I won't have huge horsepower, but should have a fun weekend car.

500 on stock ports? im going to assume not.
my 69.11mm t70 can make well over 500 no problem at just over 20psi.... just not on stock ports. No one else is running this turbo on stock ports and when i go dyno it will be a good base line.
i wish i woulda got a smaller hot side tho.

There was also a sheet with a AF61 that put down ~415 at 16psi.
