Yeah the 50cc's or so that a 1mm bigger bore on each cylinder will give me probably won't make much difference at all. It may happen and it may not. The 88mm bored 2.3L 5SFE block that you put a 3SGTE head onto (custom from ATS Racing would be much closer to a square srtoke, but in my case I don't see it making that much difference. IF I can find somewhere in-country or in the ROI to have it done relatively inexpensively, then I will do it anyway for the sake of completeness, but if it had to go over to the mainland to get done I'd just forget about it. You're talking £100 at the least for a one way pallet to England from here. Then it has to come back again. Yes, apparently the 5SFE's are built with a forged crank. They're the prime choice among tuners and DIY engine rebuilders to stroke out the 3SGTE to 2.2L, but I think your plan is best, just grab one if I can and have it machined down to have as a spare. A "made to fit" performance crank machined from alloy steel is always going to be the better choice, even ifit does cost a little more. If you could find me the names of some I'd really appreciate it. My search has returned nothing so far. There are a couple of rally prep places close by here who will probably be getting a call from me at some point in the future about doing a few bits and pieces, but as far as actual engine builders go I've drawn a blank. The BC stroker kit looks the business all right - I can't help but feel it's cheating a little though... Just grab the whole lot in a kit and drop it in. There's something appealing about selecting your own pistons, crank and rods that just appeals to me In all seriousness though, the BC kit is top of my list at the moment because it's so much better value than the original kit that I'd chosen, where the JUN custom stroker kit was a hair over £2K for just the crank and a set of pistons that I wasn't going to use. Shipping between NI and Eire isn't bad at all, not nearly as bad as going the other way. Courrier services here used to charge us anything from £15 to £50 to send cases down on a return journey to a place near Dublin which used to do our powdercoating and laser cutting, before we started getting that done in Belfast instead. If I can get some of the work done down there I will, it's always going to work out much less expensive than going over to England with it. As I've already said, a pallet is £100 each way up to a certain weight.
