Yeah I wanted the 6spd for strength and ended up costing my 4k when it was all said and done between clutch and LSD. If I drive it a couple more million miles maybe I'll recoup in fuel savings. But I did sell my 5spd swap when I was done that paid for some of it.
Speed costs money. This is my quandary as well:
1) VNT17 and be done with it, considering my current mods, and leave the tranny alone. $900.
2) Add a 6th gear onto my current transmission, or do a 5th gear swap. $400 or $1,500.
Total $2,400 at the worst.
OR, the really expensive way, if I really want to get beyond 180hp/300 ft. lbs. of torque:
1) 1756vk or bigger
2) new downpipe/exhaust
3) 6-speed tranny with quaife ltd. slip, new clutch, etc.
4) Rosten rods, which means cracking open the engine.
$6,500 at best, and probably more, as it doesn't even include labor, minus sale of the 5-speed... And this is just the beginning, as I'd probably want to upgrade my intake, intercooler tubes, and etc.
YIKES!
I'm leaning towards the former, since this isn't a sports car. If I want a sports car, I should probably buy one designed to be one from the factory...
