Not sure if a 997 GT3 can use the DSC PASM controller, but if it can, that would make the ride far more streetable, car remains stock (DSC is very easily R&R'd for factory controller).

There is a 50k mile 2010 GT3 for sale on cars.com

I had a DSC on my GT3. It smooths out the ride but not as soft as a Carrera.

Was your DSC version programmable and would the suspension support "softer" settings?

Busta Rib

Yes, it was programmable and for a .2, but I didn't make any changes and installed out of the box. My car also had PASM and I drove it in both settings. Normal was still too harsh but a lot better with the DSC than without!

A previous post talked about stand alone engine management vs. integrating an OE GT3 ECU. AEM makes some plug and play options for programmable engine management. Might be an option for a GT3 swap?

big thanks to @NAMR6MT for allowing me to test drive his Cayman with a 3.8 stage 2 tracker performer engine built by FSI. Not everyone has the confidence to let a stranger to drive their car. I hope my driving was acceptable to you. haha

Anyways back to the engine. I got to drive the car for about 20 mins with partial and full throttle. The engine has a lot of grunt down low and happily revs to the redline, which is unaltered for this build. The engine feels extremely smooth throughout the rev range, way smoother than my stock 3.6 engine. And yet it responses like a engine with a lightweight flywheel. I know that it does not have it be because Jake hates LWFWs. The engine just feels effortless all the time and feels like it has very little internal friction. Heel toeing is even easier than my car with the modified GT3 throttle body by the way.

One of the most important things that I learn from talking to @NAMR6MT is that, there is a great deal of flexibility and customizability for the stage 2 engine. You can go for a 100% street car that aims for reliability and average power output over out right peak power. Or you can ask the engine to be built to be more track focused with great peak power and higher redline just like the GT3 engine. Below is a stage 2 engine revving to 8k rpm. I was told the engine shown in the video sacrificed low end for greater top end output. This basically makes the GT3 engine swap obsolete.

Given the 3:1 weight to power ratio of your old R32 coupled with the fact that you also currently have the Numeric SSK, I was confident in your driving skills. You did well. The car seems even faster sitting in the passenger seat. If I had to do it all over again, I'd go with FSI. I love the engine and the process from start to finish was painless. That company is so efficiently streamlined.

I think the track performer + is possibly now referred to as Stage 3. I am in line for a stage 2 and so far I have not had any options to customize redline, but maybe that comes later? Some of the options I have are CP pistons, race level balancing, performance ignition coils, GT3 TB and IPD Plenum, a tuning package add on, and a few more things.

So far my experience with FSI has been awesome and I can absolutely echo that they run an extremely tight ship, it isn’t just a Jake thing either it is the whole crew. If anyone is skeptical they should watch one of their presale webinars (you may have to get access from Jake).

I was also thinking about something like this - that’s how I found this thread actually.

My ideal daily driver 997 would be basically GT3 engine+transmission+shifter on a 4S/Turbo chassis.

I had/have 997 Carrera 4S and 997 Targa 4S. I also had 986/987 Boxster S, 997.1 GT3, 981 GT4, and 991.2 GT3. (All of them with manual transmission.) 991.2 GT3 was obviously the best sports car but with $200k price, tough suspension, low clearance not the best daily driver (maybe one day..) At the same time, I like how 997 4S has a good balance between sportiness and versatility. But its engine definitely lacks character of 997 GT3 engine (both from how it feels and from performance aspect). 997.1 GT3 at the same time doesn’t have PSM and is RWD so it is far from ideal in rainy Seattle winters.

I don't believe that's an easy build. Might be better off just buying a 997 Turbo which is essentially a Mezger GT3 engine in an AWD chassis. Obvioulsy the characteristics of the turbo engine are not the same as the high-revving GT3 motor, but for the real world difference, you'll save yourself a lot of money and headache just buying the Turbo.

Yeah, I test drove 996/997 Turbo several times and didn’t like how it feels with MT compared to 996/997 GT3. But yes, I understand it is not that easy to do. I should probably just finally switch to Taycan Turbo S and forget about that crazy idea (Waiting for them to depreciate even more - you can now buy a good optioned CPO one for ~$130k which is much better already than $210k new but still a way to go )

I don’t know fellas, I see gt3 engines (991-992) for 23-30k…. It’s gonna be some work to get things right but it’s doable. I’m pretty sure no Porsche engine builder is getting you gt3 levels of power for under 50k…
the fsi owners rave but I’d really like to see a dyno sheet as opposed to all the talk about feel….

a m97 4.3 topped with an x51 airbox/plenum would be a beast but all in you’re looking at 60k…. That’s a lot of money to still be wetsumped and not track ready
