Michael: My amateur club racer efforts in SCCA E Production and ICSCC rules have gotten me down to the minimum weight of 2250lb with driver (180) and 2 gallons of fuel (12) at the end of a race. This is with an N/A 8V, 260HP motor.
So the car weighs 2058lbs empty, putting me 90 lbs more than your ...

I found a 16.2mm freeze plug locally, sounds right to me. I like the JB weld idea. I'll see if Michael knows the real deal, this motor will have one of his heads on it.

Thanks Tom

Thanks Tom, I'm pretty sure it's 16mm. My next question is installation. Use anaerobic flange sealant? Permatex Ultra Grey? Freeze it first?

A race from last year in the 944 E Production car.

Very interesting post considering my current application. My current off-season race car build will split between two classes. One will be the E Production 2.7 8V N/A with single TB/stock manifold and the other is a Super Production which allows ITBs. If it works out, I can swap configurations and ...

This is my E Production 944. I have a build post on RL but just joined here. Covid build in 2020/21. I've been racing it for two full seasons in the Pacific Northwest with great results. It's an N/A 8-valve 2.5L that weighs 2295 lbs with me in it. Extremely fun to drive and very competitive.
