Ok guys im building a engine for my na 7, and im looking for what you guys think is the best combination with the parts I have.
S4 turbo ecu,afm, pressure sensor
S4 t ported irons
S4 turbo engine in need of rebuild
And s5 na engine bad stationary bearing and e-shaft
Im thinking of using the ported housing on the turbo block but use the s5 na rotating assembly( rotors, counterweight and flywheel)
Car will get custom turbo manifold, external wastegate, s5 turbo, fmi, 550 injectors walhbro pump.
What do you guys thin. Am I missing something any suggestions I know I will have to tune.

 

I forgot to mention I plan on dd and around 10psi of boost.

 

The NA flywheel will not work with the TII trans and starter. The S5 NA rotors have been proven to work before, but you have a much smaller margin for error when tuning compared to the TII rotors. I'm not exactly sure how safe it would be to run them with the stock ECU and timing.

 

Since this is a daily driver,play it safe and don't try to reinvent the wheel

 

I'd go 9.4 Rotors on stock computer or get a standalone

 

I sat back and thought about it im thinking 9.7 is too ambitious, I don't have other t2 rotors but I have a set of 9.4 with their rotating assembly I may use those and install a safc to clean things up until I track down a standalone.
