I too have been researching the injector thing. IDI injectors aren't sized differently, it all depends on how much fuel is pushed though it since they pop open. Its not like a TDI injector with a certain size orfice that is enlarged for more power. I have come to find out the different numbered nozzles eg 253 293 only refer to different updates and changes that were made as they revised the design of the injector tips. Whether is was for cleaner combustion, less noise, etc... As the years went on the numbers increased as bosch release new and better tips.
As for the intercooler, I've got that covered with the water/alcohol injection. It is just as effective if not more so since I can tune the injection amount.
Whats really going to step up the performance will be the ARP head studs. This car with 25lbs boost and fuel to match is going to be really mean.
I'm working on the manual. At least I finnaly got a D24T bellhousing and flywheel. I'm wanting to do a T5 swap but my buddy that just bought his 760 may want to sell and its a m46. We may swap and sell his car as an auto. That would be straightforward and when I blow it up I can go to a T5 then.
Whats wrong with the oil cooler? I know its not that big but for how I drive it, I would think its alright. If I was rallycrossing it and under load for a long time I could see doing a larger one, but most of my running is messing with guys on the street or just getting into it for a quick hard run. Hell it holds 8 qts of oil!
