I took the same exit as her and pulled in on the opposite side of the pump, struck up a conversation and got a date (not a small feat given my less than prince charming looks and less than charismatic personality). The gearing of the Boxster made better use of the power. I think I could take the S in a quarter mile sprint but I can't touch it on a roll from 50 MPH. I run out of transmission at 127 MPH. Plus the NA kappa is a real pig at high speed. The suspension on the NA kappa is still way too soft for this type of driving. Redline/GXPs are totaly different at speed than the NA kappas due to the upgraded and firmer suspension
The gearing in the 2.4 kappa tranny isn't very good for a modded car (or stock car for that matter). I cannot run WTO in 1st or second due to the super low gearing. The General in his infinite wisdom gave us a tranny from his parts pin, the same one that's used in the Colorado PUs. My biggest complaint I have about the kappa platform is that they shift like cheap pickup trucks. The gearning in the Redline/GXPs is musch closer. I would like to find a wrecked Redline/GXP and scavenge the tranny from it (direct bolt up???)
I still think you would be better off trading for a GXP. Factory turbo with warranty, gearing better matched to power and a way better suspension. I think the GXP may also have some badging and interior upgrades.
I have not driven a GXP to see the difference in gear ratio's. I do wish I had, what I think is refered to as a taller 1st and 2nd gear. You are right on, 1st and 2nd are just grannies trying to get to 3rd, were all the action starts. Short of buying a new custom Tremec, I'm not sure what our options are. Are the GXP and NA trannies the same with different gears and interchangeable or not. Not sure of the aftermarket gear availability either. If I upgrade to stage IV this winter, I think the tranny will be even more of an issue. While I'm talking to Bill jr. I may get his opinion and do some investigating. Probably drive a GXP for a baseline. This thread has deviated off topic a bit. I think info back about a blown motor is going to be slow coming and held close to the vest for obvious reasons.
