Is the information below correct for a UK STI??
"Tuned by Subaru Tecnica International Inc, up to 80 per cent of the STi’s all-alloy engine is new compared to the standard turbocharged 2.0 litre four-cam ‘boxer’ unit as fitted to the regular Impreza WRX. Engine strength and rigidity are boosted by using semi-closed-deck cylinder blocks, reshaping the piston head, fitting screw-in type connecting rods and using forged pistons and shimless valve lifters."
I was under the impression that the UK STI used those Hypereutetic pistons and that they were a bit of a weak point when it came to tuning??
I'm just thinking ahead for my 400bhp!!
