Lets see, planning to get ek hatch, with gsr motor, greddy turbo, then then skunk2 cams and je pistons, but do you need to tune the car or something, to make it the right speed

 

run....run fast

 

Make it the right speed? What are you trying to say?

Tuning = adjusting ignition, fuel ratios, etc., usually with the help of a piggyback fuel computer. Cams can be "tuned" by adjusting cam gears' timing.

 

Another thing...
Skunk2 has yet to release their turbo cams, according to their site. Also, you might want to consider throwing some new rods into the mix, as well as a Hondata S200 and budget for 4-5 hours of dyno time.

 

Tuning means that you are getting the most or closest to most power through fuel curve, timing, Fuel pressure, cam timing are where there supposed to be so you get the power through the powerband

 

true, the full power potential of your setup is realized....
