Road and Track
we have 1 set of 4 pistons, 0.5mm oversized. with rings, $225 set

i can get +1mm , but special order, typically 4 weeks

most engine reconditioners don't like +1mm cause the block walls get to thin, especially #3 cylinder

these are the standard design domed top piston used in late 3SG's

Cheers thanks for that, I will be in touch very soon, just measuring up crank etc. to get final build list.

and if you go forged you could also look at custom length rods to change the rod stroke ratio.

I think there was a mob in aus which made itbs to bolt straight onto the inlet manifold of the gen3 once you removed the acis section

Cheers, if I was 20 years younger I would definitely run with that LOL. I am just looking to build a strong motor without losing too much bottom end and drivability but still a good increase in power when I want to wring its neck.

Cheers thanks for that, I would use std Toyota 87mm pistons or OEM replacements if I could find them, would go forged if I had to. I know Wossner do a forged 87mm but at 12.5:1 its probably outside using 98 RON fuel safely.

other than whats already been mentioned, amayama, sqengineering.

but do you want std toyota pistons or forged with increased cr?

Yeah not much of an increase hey, but it will increase airflow, port velocity and torque at lower revs which is the main aim. Anyway back to the original question, do you know who can supply/get what Im after?

2045cc> 2022cc is hardly worth it imho.

Going to 87mm for larger capacity, increased comp ratio as well. Already have 264 Ex cam and 272 In cam, pulling engine down to port heads, balance crank, forged rods etc. I know 87mm is at the limit for the bores, vehicle is just a weekend car that does no more than 2 or 3 thousand kms a year, don't want to turbo it as I want it all motor.

stick with 86.5mm if your bores clean up at .5mm os

Cheers, I have been in touch with Gorilla, waiting on a reply. Looking for 87mm OEM style but forged if they cant be sourced.

Hi, does anyone know who or where stocks/can get pistons for a Gen3 3sge found in an 08/96 MR2 Bathurst model?
