Rough pricing:

‘...somewhere between £115.0 and £135.00+vat per piston.’

I would be interested in a set.
As I would like to get mine rebuilt in the future and start from scratch.

This isn’t an overwhelming rush of interest! Am I going to have to buy a single set for myself from Mittelmotor...? :shock:

By the way, MittelMotor would cost about Euro 1,900 for a set of racing forged pistons including (I think) tax and shipping. They suggest overbore 88.5mm and CR 8.2:1. Double checking stock. They apparently have a ‘thermal barrier’ (coating?) and a ‘tread coating’ (skirt?) to reduce friction.

I know one who might be interested, but it doesn't seem enough. Have you checked with JE for example? They have made 931 pistons for decades.

Thanks. I’ll give JE Pistons a call too (just tried but the expert’s not in yet).

Colin I guess isn’t a regular visitor. Ollie has just returned to the forum in the last 24hrs looking to build an engine. Alan has suggested he’d join in. So with yourself there’s four for you. You haven’t confirmed the plan or price with Omega which would be at least half the price of Mittelmotor at guess.

Whilst JE make these pistons, when I enquired some years back they expected me to provide all critical dimensions, not just the CR required. In addition you’ll need to factor in shipping and duty from US. Expect them once delivered to be in a similar ballpark to Mittelmotor.

CPS in Italy have them on their website in 87,00:

I asked for a price around a year ago and they quoted 780€ (+tax I guess, so roughly the same in GBP but taxed) and 30 day delivery time.
They would have done a single set with no problems, so probably even cheaper for a group buy and there should be no compromises in finding a size and CR that suits everybody.
No personal feedback on them however.
Hope this helps
