Very impressive Mike. Congrats with the new found power.

Mike, does the SR20VE have the VVL system on both intake and exhaust cams? If it's only on the intake cam, would you try retarding the exhaust cam?

What I'd also want to know is do they make adjustable exhaust cam gears for the ga16de. Also if I were design a 4-1 header with 1.5 inch primaries, stepped up to 1 5/8. Long primaries of course maybe be stratching back behing the rear engine mount and using a 2.5 inch collector, that tapers down to 2" tapering back out to a 2.5 " exhaust. Do you think I could make some numbers.

Please forgive me for cluttering your thread with GA stuff but by time all those nifty SR20DE goodies get shipped to my country we'd pay an arm and two legs for it. So please help me out.

How much do these mods cost when you add them all up?

There is a pesky (civic type R)CTR here with some race prep done to it. It runs the quarter in 13.6 on street tires he claims, which is quite believable since he last week beat an ITR which runs 14.0 on the 1/4. This CTR claims he's only making 175 to th wheels. I was wondering if I should turbocharge an SR20 or do these NA mods and see if I can match him. What are the chances of me doing 13's with this NA setup?
