Another piston Q

[Keasbey]

I am currently rebuilding my 2.3T, and I was wondering if these pistons are good or not...

Should I buy in a autopart like napa, or ebay is okay?

I dunno if you should use flat top pistons...wouldn't those create higher compression?

Flat top forged pistons were stock on the 79-81 carb turbo 2.3L's.

You would need to check the compression height. Dished pistons would be better but you could drop the compression a bit by opeing up the compression chamber and unshrouding the valves.

I've always been under the impression that you use dished pistons in boost applications...

 

[Anlushac11]

Ideally you want to lower the compression ratio to improve volumetric cylinder filling.

I think you can get forged dish turbo pistons from Race Walsh but I dont have a current catalog.

Just for reference, you can get stock replacement forged turbo pistons from autozone for like 40 bux each...maybe 35. They are speed-pro brand.
