I appreciated Phil's comments but didn't want to respond until things were headed in the right direction(in other words, I made my intent a little more clear).
My weakest area of auto knowledge is electrics and turbos. I imagine to get more lower and higher end performance that Phil is suggesting would include a programmable brain, custom cams, air/fuel sensor, modern turbo and properly flowed intake, head, and exhaust? $$$$$ Is that where you are going, Phil?

Yep, most of that, not sure about the brain, but most importantly a full re design/rebuild of the induction system and larger intercooler and oil cooler. Keeping the air cool is essential. I'm looking into superchargers at the moment and 2 stage turbos. Lighter flywheel will help too and not break the bank.

Breaks go without saying as the stock aren't great by even family car standards :? You Feds are lucky you have the larger rims, I need a new set of wheel before I can fit bigger disks. :roll:

If you want a cheap ~280bhp you could do what Elanlover is suggesting and add nitrous oxide injectors into your air system which could give you about +40 hp for about $600 US. :wink:

Nope, don't like Nitros. Truth be told, I don't care for turbos, either. I really like na and superchargers. But that's a whole other direction. $$$
3:15 in the morning and have been reading old threads for hours and days. Starting to get a good feel for what needs to be done. Clean the flow (intake, head,exhaust) and fine tune. Maybe just hybridize the stock turbo for now. Improve cooling including induction. Etc. Make it a high end street/rally type motor if that makes sense. Stage 3. Very usable.
Tired, night all.

You won't get boost at lower revs with a turbo very easily. A smaller turbo would do this, but you would get less boost higher up the rev range. A hybrid, like Phil is suggesting, is a more modern apprach which may work better.

A supercharger will give you boost at the lower end, but this is mechanically driven, so pulls its power from the engine. A turbo differs here because it uses energy from the exhaust gases which would otherwise be wasted, although driving the turbo will still create some extra back pressure.

Another way for more power may be to re-profile the cams. This is likely to cost a small fortune in development though. Simply lifting the valves further is no guarantee for success. This is also likely to make the engine run rougher too.

If you are desperate to save weight, the standard seats are very heavy. I am sure you could replace them with something considerably lighter.

Not only $$$$ but with the higher rpm I would think opening the block to balance the parts...$$$...$$$.

I have to agree. In fact, if you stuck a V12 in it Mike Harding could still balance it out quite nicely.
