We don't pump our own gas in Oregon. A 16 year old blonde chick didn't hear me say PREMIUM and didn't read the label in my gas door. I got 87. 5 miles later at WOT, piston went POP. Find the topic. Search on the word 'autopsy'.

Power? Never been on a dyno. But I've run my numbers with my gearing, and also calculated my BSFC numbers, and everything comes out to 310-325. Stock injectors in our S1 L67'* are supposed to support 320hp at 4.0bar (which is the pressure I'm running them at).

But that'* misleading. The S1 makes ALL it'* power on the bottom end. Put that same horsepower in a S2 that shifts at a higher RPM, and you get better 1/4 mile times.

so with my car at 154,700 miles would it be safe to removed heads and cam and install a new camshaft and pick up another set of heads from a salvage yard and port them and have the local machine shop rework them and then port match intake also. or would it put to much stress on the bottom end and blow it out.

You will not blow the bottom end out unless you do something stupid.

If you have a machine shop do your porting and matching, you'll have two problems:

1. You have to tell them HOW. They have no experience with your motor.
2. You'll have to pay them for their time.

We need a MUCH better idea of your REALISTIC budget, and what your goals are. I'd hate to see you spend 5k not knowing what you want, and still have to pop another $2k into your trans (you will) when it'* all done.

A turbo will definetly give the highest numbers once you get into the multiple 1000'* of dollars. You will need to find someone who can tune for your PCM setup.

Fabrication will also need to be important. Just welding a turbo to std manifolds isn't good, they need to be BUILT.

Turbos do not have to be "laggy" either. Properly sized housings and turbines are key to any good setup...

I wouldn't do a custom turbo setup unless you knew what you were doing with everything. Read up in books if that'* what you want. The pre-fab kits are good for 3800'* but only for S2..

...the time it would take you to figure all this out and all the labor you would have in putting it together, and all the stress of tuning that beast would probably equal how much this guy is asking....which I think is a lil high, but....
