It’s easy when you know what you're doing.

Easy Mode - e85:
High Pressure Fuel Pump (Autotech, Corksport)
Intake (SRI or CA, 2.5/3/3.5 inch) *3+ needs a tune
Downpipe (3inch, preferably long (testpipe and Downpipe))
E30 Pro Tune (Freek, PD, Nishan, etc)

Harder Mode - 93/91:
High Pressure Fuel Pump
Intake
Downpipe
Catback
Intercooler (CX racing piping + TR8 or TMIC upgrade)
Bpv or BOV (Turbosmart, Corksport, Cobb, 50/50 preferred)
EBCS (Grimmspeed, Cobb) *3 port needs tune
1 step cold plugs (NGK to .024-.026, check forum)
Pro Tune

My current setup:
Autotech High Pressure Fuel Pump
2.5 in Corksport Intake
3inch EBay Downpipe
3inch Jegs cutout
GrimmSpeed 3 Port EBCS
1 Step Colder NGKs
CX Racing Front Mount Kit
E30 Tune from my friend Craig

E85 makes 300 whp very easy to achieve. Very helpful for those of you who don’t have access to 93. E85 is also a huge cooling factor, which means more timing and an overall better running motor.

Each mod has a reason; if you want my reasoning please comment

Tune is key!!!
