only you can really answer that question...i've spent ridculous amounts of cash on my car and most people think it's a waste...not me.
Keep the Pro5 stock or lightly modded and pick up a Miata for track duty
Re-read your post. you want a 1/4 mile car? Don't bother with the Pro5.
Go get a foxbody mustang
Ide kill just to get a damn 5 spd into the thing..that would make this car so much more appealing, love the tiptronic for convinience, but ...4 gears..is
FAIL...
That and just the whole concept of boosting an automatic car that i want for "track" purposes..seems a tad pointless, ya i can drive the hell out of this car with the crap thats in it, but i break it enough as is...boost with this glass tranny would be scary...
