MonkeyWrench Racing in the USA has lots of exprience with the 2GR's in one of the Lotus's...... They sell forged conrods and pistons for boosted applications including a piston to drop compression down to 9:1 The mechanical side of things would be straight forward in the right hands, I think getting an aftermarket ECU to working right to tuine the thing properly would be a big headache. sorry for bumping up an old thread - any updates on the turbo install?
