more desirable turbo for street, TD06 or TO4E or S
 

Better turbo overall, faster spooling, hp output at 14-15psi, anyone know or have experience. Is the Tdo6 bigger than the Apexi RX6.

TD06 is the turbine for several Mitsu turbos, all of which are pretty small (20G I think is the largest of the TD06's) The TD07 turbine is a better sized choice.

I have a .60 compressor, and a .81 p trim hot side TO4S. It is an ON/OFF switch. it makes only 325@15 psi, but it is instant, like a V8, it pulls as if it has full boost at 3000rpm, hard to say because it happens so fast, probably a little later, but not much. I will be trying my "undersized turbo" theory with a T66 .81 Q trim next. The popular hot side is a 1.00, or a 1.15, so we shall see. A 1.00@ 25 psi is good for 490 on a street port, so I am hoping a .81 is good for 450@25psi with much faster spool, stay tuned :D Carl

Actually the larger 25G compressor can also be seen paired up with the TD06 turbine. I dont know if you would want anything bigger than a 25G with a TD06 though.

I liked my T04S setup w/ streetport and FMIC at 14lbs... 425rwhp..! only lost 2x to V8 domestics w/ enough in their bottles to feed all the kids in the whole town.... T04E is better for in and out of traffic type situations though I sure...
