986 3.6 conversion vs 987 3.4 DI

North of $20K--yes. been saving my pennies for 2+ years for this. I'm guessing the difference between a 3.6 and 3.8 is not that significant since the limiting factor is not torque/HP, but traction and suspension to handle the over abundance of power. I'm not by any means an expert on the tech aspect of Boxsters and Boxster S's but except for the obvious interior differences, once you upgrade the suspension (wheels included), there is probably no difference in performance; unless, of course you think a 6 speed transmission is that much better than a 5 speed. I'm old school. Grew up on 3, 4 and 5 speed stickshifts. My reasoning is that 1st to 2nd gear will not be so quick a transition with all that low end torque. I'd like to hear your thoughts on this.
At one of the Drivers Ed programs in Memphis last spring I let an instuctor drive my boxster with all the suspension/wheel upgrades and 2.5Liter engine I had at the time and asked him after the session to compare it to his 2003 Boxster S. His response was that the difference in power was not noticeable because the handling of my car was so much better than his.

I was thinking mainly about the 6 speed and brakes. if i was going to do this conversion i would prefer an 03 or 04 model. I think the 5 speed is a little sloppy for such an upgrade.
after driving the six speed you can see how loose and clunky the 5 speed is . Are you going to upgrade the body work ? A fixed wing and a front splitter would also improve this package. you need to think about the whole package to get the most out of that 3.8

I can also add that the boxster handles the increased power with no problem at all . it's like it should have been built that way to begin with. it will be just like your 2.5 but those same attributes will now happen at twice the speed !

I'm also getting a GT3 front spoiler, (to allow more cooling for the engine) and a modest variation of the stock retractable rear spoiler. You are probably right about the 6 speed. If I'm really unhappy with the performance of the 5 speed, I can always upgrade at a later time. You can see the rear spoiler on one of the upgraded boxsters at www.roockautosport.com. I really don't want the my boxster to look too modified...a sleeper if you will. According to Fabian Roock, a fixed wing (like one seen on his website) would not add to the overall perforance of the car. It's more for looks.
