Makes sense. Another not very expensive alternative is to change your P&C to low compression ones (you can find used and sell yours) and have a retune by Todd@Protomotive for example. You will benefit from the twin plug and larger valves (if I recall correctly) among others and be able to run higher boost.

I LOVE THIS THREAD. The guy i bought my car from spent 32k for the Protomotive Stage II at Protosport on my car. Beefed up internals, etc. I paid less than most C4S were going for in 2002. Actually a lot less than 60K. Car only had 14.5K miles and engine had less than 2K.

It depends on whom is to buy your car as to value. I know most Pcar guys value my car lower. However, I have been offered a LOT more than I paid for my car from Pcar guys and others. But it would only be for sale for the right price for me.

I believe inherently the normally asperated car may have more potential because of its twin plug design. 993 turbos being single plug. I know the turbos can be twin plugged, but I know it is not cheap. I'm not a great mechanic, but I do believe it makes a difference.

Right now, I would like more HP (you can never have enough), have the turbos moved in front of the cats for less lag and a few other minor mods. I will say this, my car is very drivable around town, air blows ice, sounds incredible, when it hits 3800 RPM, its a rush.

Potential of the cars is basically even when you start adding parts.

To get big power out of an NA car reliably, you will most likely need lower compression pistons, whereas on the TT cars, twin plugging is useful (though I would argue not 100% necessary).

At the end of the day, to go much beyond 500bhp, you are going to be spending a metric ton of money regardless of starting with a turbo or NA car.

^^ "While they're in there" you really need to increase it to a 3.8l, since you already have the twin plugs.
