Default 2.4l engine.

From what I have read, the SRT4 has a better intake, exhaust, and some other stuff.


Why not order those parts and put it on the GT?[:I]


<-------(Not a mechanic)How hard can it be?

It would be very easy to do...if your engine was on a stand. 2 very different vehicles. The engine compartment in the GT will not allow room for the short runner intake of the SRT.

not a problem at all, just letting the original poster know about this, as the srt-4 exhaust won't fit the pt.

Mopar (or other) cat-back exhaust will bring a normal PT Turbo up to SRT-like engine performance. The intake differences aren't substantial.

Is that the reason that the demo cars at the PT Invitational felt so strong? If not why? The 220hp car that I drove hauled a**, spun the tires in the first to second upshift. My Stage 1 won't/doesn't do that any more. I get (according to my Autometer gage) max boost of 12 then down to about 10, and then it drops off. Anyway the car will pull like all heck if I keep my foot in it. BTW, I'm not asking you to diagnose my car, but I'm asking what the hell did you guys do to that 220hp car that I drove at the PT Invitational to make it run so good?

I don't remember the 220 hp cars having the Mopar exhausts on them. Granted, I was only driving the Stage 1 car so I may be confusing things.

As to why it felt so good (relatively speaking), I haven't the foggiest. The eight cars we had were all just average fleet cars, detailed and then stickered to look pretty. Having said that, I think you are the fourth or fifth person complain about performance being really good when you installed S1 and then some time later it wasn't as impressive. At least one complaint was due to the different temperatures outside affecting the boost (which it is supposed to), and you have a boost gauge as well so there might be a link there. As for whether it is faster or slower, only a trip to the track would be conclusive - and nobody has really done that but me. My car has 8k miles on it now, as fast as the day I got it (well, actually the week after).

If we do establish it is slower, then you might want to play with the wastegate like I have suggested a few times (helper spring, bending the mounting bracket) due to possible "relaxation" of the bent wastegate arm.

Thanks, I'll do a check on the wastegate bracket adjustment procedure.
