i have only 700 miles on the car since the rebuild, and im unsure of my setup at the moment.. anyone run a t3/t4 with a street port and a 3"turbo back exhaust..??? curious if the t3 is to small??!! i like the low end boost it builds but dont know if it bottle necks to much? im dying to rip it next to my s5 t2 with a stock turbo and stock ports, but of course its not broken in yet so i cant!! if anyones running a similar setup or you have tried it, help me out! let me know what im to expect..

 

i want to know what this T3/T4 turbo is people keep referring to?

in the past people used to modify a T3 flanged turbo with a T4 compressor to make more power with increased response but T3 turbos now are a thing of the past yet i still keep people referring to any random turbo they have as a T3/T4 turbo. a stock hybrid is a application specific/T3 or T4 hybrid(usually a T3 based T04x cold side).

T3 flanged turbos are too small for rotaries in general, i would not build a manifold with a T3 footprint because it is too restrictive for rotaries to breathe properly.

whenever you upgrade the turbo you need a way to add in fuel otherwise you will have a driveway ornament. you can't just throw on any larger turbo and make additional power for free(fuel makes the power, the stock fuel system can only really handle about 200whp).

series 4 has a RX7 specific footprint(one mount is offset), series 5 has a footprint similar to a T3 but it is still smaller and the ports are offset to one side. almost every aftermarket rotary manifold is a T4 footprint.
