I just went and bought 2 boxes of cat litter, 16kg in each. I had to carry them from the shop to the car, probably 300 meters away...32kg at the end of that I was thinking hmmm 25kg saving on the front axle is a massive amount of weight, by the time I put on the rear carbon fibre boot lid I am over 32kg saved.

The thing I cannot get my head around is if you go for 2.2 or 2.4 then you are not going to rev it that hard, do you therefore need cams and pocketed pistons? I get that you don't want a really old crank in there but my car has only done 36k on the engine...?

I expect I just need to be patient and save up for the full spec engine, cams, crank, Rods and Pistons and hope that I can re-use my head after it has had some porting done and a rebuild.

Would a 2.2 or 2.4 ever be revved above 7,000 rpm?
