View Full Version : 3sgte pistons fit in 5sfe block?

06-14-2016, 06:49 AM
has anyone ever attempted to use the forged pistons out of a 3s block in a 5s block? I have a stripped down 3s block thinking of taking the rods and pistons out and rebuilding my 5s block. I would consider getting some cheap eagle rods off eBay. you have to machine down the crank to fit the 3s rods so if anyone is interested I have a 3s head I could sell and rods, oil pan, oil cooler, water pipe.

I built a fully forged 5sgte block but thinking i need to get my celiac back on the road soon and wait on the MR2 5sgte build. something that will be more reliable.

They wont work. There is a custom made piston to fit this application.

Yep. Bore size different, and the wrist pin position needs to be custom. ATS has figured out the specs and has them available to order.
