If all you want is an injected TR performance, I’d do this. Buy a us spec car.

TR5 camshaft, still available in U.K. and a bit better too than the original. Shave the head to at least 9.5:1, fit flat top pistons, a Lucas D25 or 26 dizzy, the equivalent of the SAH 6-3-1 extractor exhaust manifold, two 1.75 SU carbs and bingo, you’re there. Ideally, if the donor car is a late model 6, email Chris Witor in the U.K. for a 215019 head. These didn’t go to the US but we’re the best heads of the lot. Chris will confirm this and he’s a Triumph performance specialist. Goes without saying you’ll need anoverdrive. J type is ok but A type better imho. You’ll then have a car that is the injected versions performance equal in every way. These things are what we do in the U.K. to all 250s and carbed 6s that find their way back here. Good luck

Doubt you’ll find too many in the US with experience of the system. PI cars were never sold in North America in the day, though a very small number have snuck in since then. A word of advice. If you’re tempted to fiddle with the PI system, put everything you’ve learned about carbed cars entirely to one side. The Lucas system is a whole different ball game with very unique rules. That said, it’s a great setup but you need to know what you’re doing before you start:)
