Paul,
I'm sorry I should have elaborated. I took the whole things down. I had every thing balanced to 10K, after lightening the flywheel. I went to a good machinest for this.
As for the oil cooler and pump. Well I got the big pump because it could only help, no? The oil cooler was already present as I live in Atlanta and heat is a concern.
As for the P&C's, well I do believe that you have to have the block and heads machined for them to fit. I've seen a 2.2L and it looks identical to the 2L. I've also seem a set of 3L P&C, not in the car and they are stupid big.
The injectors just have to be ported slightly for better spray pattern. I doubt that you'd have to do this for a 2.2L, but definateally for a 2.4L. If you locate a local speed shop that sells nitrous equipment they will be able to point you at injector tuners.
The reason for this is that you will be needing to pump more gas to the cylinders. Now using an O2 sensor this is easliy dont by calibrating your MPS at 2500 rpm and then running up the fuel pressure until you get good flow at high rpm. The thing is that over 34psi the 2L injectors (green caps) tend not to atomize/nebulize the gas well. You stop getting a gas mist and start getting large gas drops and streams. You can get the injectors tuned slightly, again folks that install nitrous systems sometimes do this. Then again you might not need to do this.

Again I wish I had built a 2.2L now that it's all over with. But I stuck with a 2L with a mild web cam for FI. Also lightened the cons and flywheel. Got every thing balanced to 10K rpm. Then all the simple mods that increase life; oil cooler, big oil pump, completely rebuilt heads with new sodium valves. . .
