Hey there, I'm more of a lurker on these forums but I've been on the 240sxforums.com for several years and have several thousand posts over there. I have a couple questions regarding your car and most likely would like to come look at it sometime in the next week or so.

Who did the tune?
What kind of rods are you running?
Is the crank stock?
Has the displacement been affected?
Are you using the RB25DET tranny?
What rear end is under the car?
