Couple different ways to do it. Russell and maybe Calvert sell some very oversized pistons to make a 1225cc or thereabouts.  Otherwise maybe there are specific height pin small bore pistons to make it work out for 0 deck height and the gasket for proper quench and piston to head clearance without machine work or specific rods.  We'd have to research it a bit.  All a 1098 is really is a stroked 998.  The Russell pistons are just one avenue to take a small bore and basically turn it into a large bore.  It would be a really nice motor.

I had found that VMAXSCART was still around and making their A-Series supercharger kit.  I have been researching both as I had more/less decided after my talk with MiniDave to go with some form of "forced induction".

I am actually leaning more towrds the Turbo kit as it was designed by Jet Motors (US based, so more convenient support) who have sold a significant number of the kits and their kits are also being sold by some of the UK Mini parts suppliers.

I have spoken extensively this week with Jeremy about his kit and compatibility with my current engine specs.  I am likely to order the kit later this week.  I already ordered the parts to sort the drop-gear issue from Mini Spares and will in fact be changing from the current square-cut 1.04xx ratio set to the "economy" 0.958 ratio set - resulting in something closer to a 2.95 final.
