2.4 T, E, S? Options

[Cool914]

I picked up a 2.4T core motor I am going to rebuild to go in one of my 914's, someday...
It will just befor around town, maybe autox.

Question is regarding pistons, it needs new ones and I am either going to find some in spec used ones or go with JEs, and keeping the T cams or regrind E. I would like to get a little more kick out of it while I am at it but I will not be running an external oil cooler so wondering if I go with E (8:1) or S (8.5:1) pistons, would the increase in compression ior E cams mpact operating temperature to the point where I would need a cooler. Any experience, insight?

I lkie the JE idea.
Using 2.2L pistons in a 2.4L is iffy unless you can do some good measurements.
The 2.4L pison is different.....the pin hole is relocated in comparison to the 2.2L to help with the longer stroke of the 2.4L crank. Deck height can be fixed easily but possible intererence exists at the bottom of the stroke.....checking for this is a stone bitch.You need a minimum of 1mm+ (.06 would be better) clearance from everything down that dark hole.

2.4L E motors were Brial but that was 35 years ago. Nikasil came on the 2.4L market 20 odd years back. They are un-cheep. If you have Brial they can be bored 1mm over and JE pistons can be had for this and 9.5:1 compression to boot.

If you can get a set of STD Brial PCs (& the JEs) for 1200 bucks that's a slam dunk.
