nfo on my Setup:
Need some insight on my setup. Car will be used for track days and autocross. Car already has TBE.

EVO IX is being setup with:
-E85 / 93 tune
-Kelford Cams 272 or GSC S2
-Springs / Retainers / Seats Kit Combo
-ARP Headstuds
-1200cc Ethamax Injectors
-Single Whalbro or Double Pump if using FP
-Injen Intake w/ UICP-LICP
-Forge Unos MBC
-FPRed (thinking about this one)

So my Q's are:
-What are the thoughts on KELFORD 272 vs GSC S2? Similarity?
-Retainers should I go Beehive or Supertech? Cost is almost the same.
-Is the FPRed a versatile turbo for autox and/or roadracing?
-When going from 93 to e85 or vice versa with map switcher, do you have to adjust boost via the MBC? Or does the ecu adjust boost by itself.

 

If you are using an MBC you'll need to adj the boost level yourself. ECU controlled boost however you can set up a boost profile for each map. Might be the way to go
