You can get them up to around 240bhp with the right parts, Homologation 1 cam and twin 48 webbers, they also do a header but its a bh to fit. The head won a design award, 4 cyl single cam 16V !!!! It will fit on one side of a Stag V8, mirror it and have a 32 valve 3.0L V8

I prefer to keep cars standard apart from sensible upgrades such as electronic ignition and improved cooling. I might see if the breathing can be improved a bit, but would not want to strain the engine or test the brakes ny a major power boost.

Ditto with my Lotus Excel (thread forthcoming). Some people get crazy bhp from Lotus 912 engines, but they may go pop.

Looks like it's already got a Kenlowe fan instead of the viscous coupled job?

Couldn't see any ignition box, but it needs one of these for proper retro cred smile

The brakes are its downfall, you can fit bigger discs but would need to run 2500S or Stag wheels, the triumphtune exhaust makes a difference and sounds great.

There are loads of brake options, the original setup is pretty dire. That said, with your rebuild in 2012 I'd expect the standard setup to be in tip top condition.

For better brakes all these fit under the standard wheels :
For originality you can use Special Tuning vented disks, GT6 stub axles and spaced original callipers. This is expensive, speak to Ken Clark motorsport or Brian Kitley Triumphs for the kit.
For more modern brakes the Tracker Jack conversion has loads of installs, kits from Jon Jackson appear on ebay, this uses Golf vented disks and Sierra (or other Ford, Escort/Ka etc.) sliding callipers.
SprintParts in Oz do a complete kit.
AP Racing callipers and disks from SprintSpeed.

Then there is a shed load of options that don't fit under the standard wheels, I won't list those; speak for SprintSpeed or Ken Clarke but they are only really needed for track work.

I'd also expect the engine to be in fine fettle and may benefit from having the standard cold air kit put back on rather than open air filter in the engine bay, the two inlets should be open at the very front of the car next to the rad. You can fabricate your own or get a kit from SprintParts. Good to have on a hot day.

The standard exhaust is a lovely thing, but a sports system with enlarged downpipe will make her breath a bit better.

Oh, very nice indeed. My mother had a couple of Sprints near-new when I was at a very impressionable age. Second one was red, UKW81S. First one was yellow, overdrive, should've been N-reg, but came with a private plate (5555AD). I wonder...? Nah, I doubt it survived long after being flogged to an uncle...

Neither had a laurel wreath on the bonnet, but I do seem to remember helping my old man fit Sparkrite ignition to one or both.

You're quite correct, Ken's car is running a KV6 lump.

This one however, is running a Sprint lump.

Stag or 2500 wheels won't fit - the Dolomite runs a 3.75" PCD which is not very common - small Triumphs, Metros, certain Maestros, and the MGF are more or less the only cars that share it. The offset is a bit funny too, so even some of those wheels won't fit properly.

As a kid in the late 70's my dad's friend Paddy wrote his new one off on a road called Spout Hill in Croydon. For the next 20+ years EVERY time we drove past that wall we would try to shout " Paddys Wall, I won!" first for the points!! Became a ritual, the wall where a brand new DollySprint met it's maker!

A Mangoletsi twin Weber DCOE (usually 48s choked down) manifold was a common upgrade. In the late eighties you could buy a full new crated Gp2 engine for a few hundred pounds!
