To be fair I could write the season off now and concentrate on the rebuild, I'd just rather be out there racing.Quote:

Trouble is in the few years since then, things have moved on dramatically with the Minis, the best of which are making 200-ish BHP.
I have no doubt at all it can win again, but reliability is obviously the priority.
Correct, they are apparently Metro Van pistons, although why the van would have had a different piston to a normal hatchback I'm not sure (lower compression ratio?).Quote:

I think you would be best of sticking in the up to 1400 class, as then you can still be competitive.
and for the cost of a mental LET, i'm sure you could rebuild your engine with a steel bottom end and forged pistons. and if the brazilian engine is a goer, then a steel bottom end, forged pistons and a rather large turbo would be mental! and still cheaper i'd guess then an LET.
If I was going for an LET (or XE) I'd just buy a complete car, and by selling off all the other bits I don't need, it would end up being a cheaper engine.Quote:

but would an LET be competitive in the unlimited class?
this thing deserves a 600bhp let.
are you still considering 16v head too?Quote:

Colin what's the cheapest option? A 1.0 rebuild or a revised 1.2/1.3 rebuild??
Personally love the fact this is a unique engine build and feel that if you took that away then it wouldn't be as exciting for you and you'd end up breaking or selling on eBay IMO.
16v head slips straight on a 12st block ;)

This is half the problem at the moment, I've got no quotes to work from, hopefully BTEC will sort some numbers out for me soon. The possibility of destroking is certainly something I will discuss with them, I'm outside my experience zone with this level of technical stuff.Quote:

I have a couple of 16v heads and a complete 1400 16v engine. In fact the head from this one I've got would look rather good;
