I've got a 2.4T (73 1/2) that I have torn down. This is what the pistons look like that are in the engine...
What's the difference between these and these that are typically on eBay... Also, These are both 84mm. Since they list these pistons as for a 2.2 / 2.4 is it just a different stroke between the 2 engines? If that's the case are the cylinders interchangeable? |

It sounds like you are happy with the stock '73.5 911T CIS engine. I'm extreemly happy with mine!
If the pistons, cylinders, etc. are all within spec: clean them up and put them back in with fresh rings. Since you have it apart: get the heads rebuilt, get fresh seals, then expect to get another 200K trouble-free miles out of the engine. The CIS pistons and Cylinders will last forever. Mine are original and have lasted 290K miles so far. Also the iron cylinders have the same heat expansion rate as the iron head studs so stock '73.5 911T 2.4L CIS engines never pull head studs. Heat has never been a problem with my stock '73.5 911T CIS engine. I don't even have an external oil cooler. Why did you tear the engine down? |
