Improved performance - 2000tc

I wonder if it is possible to fit lighter pistons. The 2200 ones are not too bad, but the 2000 type piston i believe that it is too heavy for a performance engine.

I've wondered the same thing, same with conrods. Also the cranks is battleship weight. Being a straight four we don't have to worry about conrod/piston weight as part of the crank balancing and lightening (Unlike say a V4 or V6).
 
Overbore the 2000 block to take the 2200 pistons and rods, and if you use the maximum oversize I think you can get it up to about 2260cc IIRC. Fit a 2200TC gas flowed head. Add a reprofiled camshaft and a pair of HIF6 carbs and your good to go, with the option of Weber's or fuel injection later if your budget runs to that.
 
Tiny, low pressure turbo a la Saab? I don't think the block is strong enough for more but with a 2200 you should be able to get V8 plus performance.
 
Big fan of lightly turbo'ing engines so you dont need extensive mods inside. Have a std factory turbo subaru, giving 185Kw from 2.5L , but it runs boost up to 1.1B. Also a Lotus 7 clone with an MX 5 1.8L DOHC with an aftermarket turbo limited to 0.5B, -insides of engine untouched - 9:1 CR, produces 160KW at the wheels, very reliable, power comes in under 3k rpm. Extra ECU piggy-backed over the std unit to control fuelling and ignition.
