The 16v Sprint engine obviously fits in without a trouble into the TR7. The extra power boost with little weight difference would have made it a good steer. Alas the Sprint engine wasn't the most hardy of units and reportedly cost Triumph a lot in warranty claims in the Dolomite.
Genuine TR7 Sprints appear occasionally for sale but most are modified ones.
I've seen various numbers quoted for those 'released into the wild' but circa 20 seems to be the most common.

The Sprint got all the way to pre production models. But Speke workers demanded a technology payment to build it. This dispute rumbled with no cars built until it was overtaken by the big dispute that resulted in the closure of the plant.
The O series or Oh dearies as the Triumph engineers called it was slated for 82MY cars but again events overtook.
It is also worth noting whilst still in production there were investigations to keep the car competitive
It was identified there was a need for a 16v Twin Cam O series for TR7, BL management sanctioned the project and this engine did see the light of day... in the Rover 800!
The O Series was a far better engine than anything Triumph built. Whilst it wasn't anything spectacular, it was easy to build and very reliable with an impressive service record. Bit like a Ford Pinto.
Triumph were very good at designing impressive things, hopeless at actually making them.

The O-series essentially remained in production until the bitter end; April 2005, although admittedly in diesel form. Its tooling was then sent to India where the last I heard it was still being manufactured.
I agree about Triumph engines, all great ideas but all shite in production.
