I have a 1900cc Power Engineering engine, which has sadly dropped and exhaust valve.

Bore has slightly markings, but would certainly live another day if you didn't mind a slight bit of smoke, would need to source a replacement piston and head, however has the power engineering cam to the below specs, and ran well when I had it in the car.

Is it worth rebuilding? Who would I speak to about a replacement piston? What work would have been done to the head to with this engine?

Cam Specs:
SX428C
Duration: 280deg
Valve lift: 0.495"/12.57mm inlet & exhaust
Timing: 34-66 inlet 66-34 exhaust
Full lift: 106deg ATDC inlet

Ditch the long stroke and fit a 1600 or go full blown 2.0 16v

 

It's probably the same engine like the 1,9 Hurricane CVH.

These were based on the 1,8 CVH (Sierra only) crankshaft with 88 mm stroke instead of the 80 mm of the 1,6 CVH. With standard pistons you'll get about 1770 ccm. The key was reboring the cylinders. Hurricane used Audi 80 5E oversized pistons (standard was 81 mm, oversize was 81,5 and 82 mm). These engines had ~1860 ccm but keep in mind... 2 mm reboring will result in a very thin cylinder wall. That's the reason why many of these engines didn't last long.

Herbst Motorsport in Germany also sold a custom made 92 mm crankshaft, with a rebore to 81 mm you'll get about 1900 ccm. But these are rarer than rocking horse shit.

Like said before: 1,6 CVH and maybe a full Zetec engine. The third option might be a ZVH. Won't make that much power (even with a good cylinder head) but at least as much as a 1900 CVH plus you can keep the original look (mostly).

 

Seems reasonable.

The 'Power Engineering' build is based on the 1600 block and head, but I think the 1800 crank but could be wrong, and something like TR6 conrods and Merc 200 pistons.

Head is currently only placed on, so I can measure and confirm the bore and stroke. Likely then needs someone to access condition of the cam shaft etc. Maybe ZVH using the cam?

I've both 1.9 CVH blocks on the shelf here, the American one is longer stroke and the other is a bored out 1600 .

I chose to got back to a low mileage 1600cc CVH I'm currently over 300hp and 13k mileage.

It's either CVH or full Zetec , the latter is a cheaper option

 

North American 1.9 CVH is 82mm bore and 88mm stroke.
One can spend $$$ porting a cvh head which does exceed flow of a totally stock untouched Zetec head.
However, the cost is high and one still has some CVH issues - camshaft/lifter lifetime, high rpm potential etc...
I like the CVH platform - in a car that came with one.
For your use I would be heavily leaning towards a Zetec build.
A mild 2 liter Zetec and perhaps a camshaft change would be miles ahead of a 1600 cvh.

Just my opinion.
