78mm crank in S2 engine what’s new compression ratio
People have skimmed the S2 pistons, and it can work that way. I know someone that used a standard 968 bottom end, and forged Porsche rods, and that worked too. You would be limiting the amount of boost you could run though.
I'd be careful with the 2.5L 16V heads, the early ones had a casting fault and were prone to cracking from what I've read.944m3 wrote: ↑Thu Sep 14, 2023 5:42 am That’s what I’m working out in my head, what can I afford to do right. That being said, I do take inspiration from Peep and others I’ve read posts from. You can do a lot with just stock parts. Won’t win Le Mans but will work just fine for your grocery run and occasional track day.
At the end of the day, it’s just a hobby though, so I’m willing to make a mistake or two.
The other thought that has crossed my mind was selling the S2 engine and just going with a 944S 16v head that bolts on to a 2.5 block. (Yes I know I will still need custom intake and crossover). I can keep the internals I have now, just flycut the pistons for valve clearance, maybe upgrade rods with lighter Molnar rods.
If anyone has one laying around, let me know. I might be interested.
