I have searched on this topic before but why would it not be a good idea to use a T3/T4 on an FD to produce 375 WHP. Its more than the twin reliably support and would allow for a nice spool and midrange. I know topend would get chocked a bit though. Has anyone tried this? If so what did you find.

Thanks

 

Most people with a GT35R (GT3540, GT35/40) are doing exactly that.

 

I understand the GT35/40 are more efficient than the T series. So that helps them some I assume. What size T3/T4 would be work the best? Maybe an .86 AR turbine not sure of trim. But what size compressor to take advantage of the T3 turbine?

 

well ,,, I'm running a T3/62-1 turbo (450whp) .... the spoolign is freaking fast... true you sacrifise hp but for me in the street is just the best way to,,, I raced an N/A 500hp-Vette in 2nd gear and i pulled first than he's....we were close to each other through the race but at the end he was not amaze for loosing the race, he was more like "that thing pulled so fast" he told me no ene ever have beat him before in terms of which car pulls ahead first... so it's been very fun to race/drive for me in that set-up...

 

no thats just a t3 flanged to4 housing its still using the t4 ptrim turbine.
although i am thinking of trying an o trim t4 with to4e compressor. this will give you great boost responce aprox 350hp+, I guess this would be 1 stage above a high flowed fc3s turbo.
