The black one right? 1000Hp or something...

Hmmm, I would think that being a Norwood vehicle it would retain value if not add some value in the future. Hard to say but I do agree with the need for more power in the TR. Craziest TR I've ever seen was one that sported twin 8-71 blowers and massive velocity stacks along with Nitro injection. It was built by Fodge back in the 80's when they were also messing about with Top Fuel dragsters, crazy old guy with a massive penchant for speed. If he's still alive he was involved with the TRD off road truck series last I saw him.

In any case dropping the Turbos and keeping the EFI shouldn't be too hard. But if true values are based on stock you might have to go all the way back to the CIS... ugggh at least it's shared with the mercedes stuff, though that stuff is getting expensive too. Given the curve on values and resto costs the sooner you start the cheaper it is. Parts acquisition is the budget killer 9 times out of 10.
