Yup, all in their own little bathtub!

Been driving the 924 and the 944 to work for a couple of weeks. The 944 is just plain smoother in every way. A good ride for mornings I don't feel like I want to be completely involved with a car.

Well, time for a 10 year update on the 944.

When I got the 944 it had 110,000 kms on the odometer, that has gone up to 125,000. The vast majority of those kms have been at the four track locations we've had locally here over the last decade. Much maintenance was done through the years; rod bearings, head gasket, head refresh, clutches, etc. About 18 months ago I felt the engine needed to come out for a major refresh. I decided to try something a little different so I installed a crate LS2 in it's place. This track season has been its first outing as a swapped 944.

The swap itself is fairly "normal", I didn't really experiment and followed what had already been done in the past and went with off the shelf solutions wherever available. The swap kit was sourced through Texas Performance Concepts.

Brakes utilize a Ford hydroboost but retain the stock 944 Turbo master cylinder and brake pedal. A Turn One pump moves the hydroboost fluid, but only to the brakes as I retained the manual steering I installed years ago. There is a cooler for the fluid given it's a track car.

There's a big aluminum radiator that comes with the swap kit, I retained the big oil cooler I was running with the stock engine. I used a Setrab remote oil cooler mount between the engine and the cooler to get the filter away from the headers where it lives on a stock LS.

I went with the optional upgrade of long tube headers with the swap kit instead of the log headers. The long tubes are made by Kooks and are a perfect fit and specific to an LS in a 944.

The swap uses a Corvette C5 bellhousing and an adapter plate to mate it to the torque tube. The hydraulic push style throwout bearing lives inside the bellhousing and is moved by a 7/8 clutch master cylinder actuated by the stock 944 pedal. The 944 LS swap clutch disk and pressure plate are from SPEC, I also went with a SPEC lightened steel flywheel.

I topped the engine off with an LS6 intake which flows better than the LS2 intake. A Lokar cable moves the throttle body and is attached to the stock 944 gas pedal.















Some of the other details on the car:

Front Suspension:

400in/lbs springs

Annual update!

Great last track day of the season here on Sunday, cool weather and a major snow storm south of us meant a very empty track. Such a fun car, LS2 + 944 = perfection.  Had a few transaxle buddies lapping with me as well including fellow long time 924board member Brockoli!

Interesting minor update as well, I had the car on corner scales again this summer, the weight after the swap is 2935lbs, so 7lbs lighted than it was before. New rims and fibreglass hood are lighter than what it was scaled with when it had the stock engine, but still an interesting result. So much for the “boat anchor” V8 theory.

These dirty LS thoughts have crossed my mind enough to price engines..

The 941 is mine now, and really it just feels like it has a lot more tire..
Compared to my narrow car with quite poor tires, and the 41 with wide A052s.. Huge difference.. It sticks incredibly..

Proper spring rates and a wide square tire setup transforms these cars. They can't keep up with something like a GT4 through the corners on a road course, but they certainly aren't left behind either.

The cayman GT4 is that good?

You think it’s better than the C8?
I have loved the thoughts of the Cayman GT4, but I got to ride for some hot laps in a C8 recently at Barrett Jackson and WOW!!
That thing is amazing..

Not that I’m going to buy either anytime soon, but maybe some day..

I drive the base model 987 Cayman with a suspension upgrade that should nudge it towards the Cayman R setup and it is by far the best handling car i have ever driven…for the money..as obviously you can always add another zero at the end of the price tag and that will surely be better.

Cayman GT4 is that good. They are incredibly fast on a tight road course. I haven't been on track yet with a C8 so I can't comment.

Annual update? Great season of 27 track events spread across the four road courses within 2.5 hours of where I live. Great fun!
