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.

Adding to this thread. Wondered about a louder cam for the 2000TC. I have the Piper Fast Road regrind, when I popped into their factory to drop off the donor camshaft they said they could do a billet cam for higher lift and duration. (I don't think there's enough 'meat' on the standard camshaft to do it with that). If you did, I'd say you'd want to look at different valve springs to avoid coil binding and maybe stiffer to stop valve bounce at high revs? On top of that, maybe consider larger, tougher valves. I notice even the TC exhaust valves can pit with high performance use, especially with a triple angle seat grind where you lose a bit of contact area for heat transfer through the seat. I've been told Rev valves are pretty reasonable when it comes to custom valves, its very tempting.
