specifics of 3sgte block Options

[enderswift]

hey everyone,

I got into an argument today about the 3s. The people I was talking with insisted that EVERY cast iron block MUST have sleeves, because cast iron cant stand up to the conditions in a cylinder.

I said that the 3s does not have sleeves, and when I jumped on google I confirmed that fact. However, I could not find information on whether the cylinder walls are plated with a harder material. Could someone shed some light on the issue? If i remember right I saw photos of cylinder liners on someones 3s block in a thread. Do we have cylinder liners or is it just the cast block? I looked through my factory service manual and couldn't find any information either.

any input is appreciated

ill put this to rest. the 3S-GTE and 5S-FE are Iron block with NO sleeves!!! The 2JZ-GTE doesn't have sleeves either and we all know what kind of power it can make. Now the 1ZZ-FE is an aluminum block that has an iron sleeve insert, but the 2ZZ-GE is all aluminum with a HMC treatment on the cylinder walls. you do not hone the 2ZZ cylinders.
