Not completely done with my setup yet so I figured now would be a better time than ever to switch my turbo. I currently have a GT35R but am thinking about going with the GT40. I know the GT35R can throw down good numbers but it says only good up to 600hp, something i hope to meet/break during the next year or so. What are your thoughts or numbers being made on your GT35R?

Search, there have been dyno results posted for both. The T3/GT35R is proven up to ~660 WHP. T4 variant should do a bit more than that. The GT40R is proven up to 750+ WHP. If 600-650 is your goal, go GT35R. If you want more, run the 40R.

 

GT40 is more laggy than your current GT35R. Whats your HP goal ?? Street setup ??

 

I am leaning twards keeping my T4 GT35R and this application is for STRIP/street use. I won't be driving much on the street so mostly strip.
