well, didnt se a twin turbo section, so i figured i would just post here. This isnt a "right now, im gonna do it" type of question, just a theoretical question about some parts i have and if they woould possibly work on my 13B.

OK, i see that when it comes to rbuo RX7's people seem to be using something like a 1.15 A/R T4 turbie housing. my question is how does a T4 turbine relate to a T3 turbine? for example, the turbos i have are:

.70 A/R T4 compressor
.84 A/R T3 turbine
wheel trim is 64.5mm
compressor wheel is 60.5mm

Now i highly doubt they would even possibly work on the car, but i figured i would throw it out there. Also have an MSD 6BTM sittin around. I do have some pretty decent fabrication skills also.
