6G Celicas Forums

Hey Guys. I have a couple questions. I just changed out the pistons in My MR2 to forged ross pistons. Now i have a set of low compression pistons on my hands. I have a 1994 toyota curren with a 3rd gen 3SGE. I am wondering can the 3sgte pistons fit in the 3sge block. also can the head gasket for the gen2 fit on the gen3 3sge block? Cause i have a Metal head gasket I would like to use to it on the gen3 block. I plan on using a CT26 and running 12 PSI on it. I have a gen 3 fuel rail and injectors, I also have a upgraded fuel pump. I need to know if the pistons can fit and work. Also how difficult would it be to do a gen2 3sgte in the same car?

Thanks for the help in advance

I guess everyone is on vacation from the forum......Any help please

lol it posted twice..

you would need to drill the gen2 HG for the gen3 head (coolant lines) yes, you can use gte pistons in the 3s-ge its the same block, unless of course its a beams (vvti) 3s-ge, is which case your going to lose huge power.... but gen3 8.5:1 pistons r fairly ideal if you cannot afford to go with a forged bottom end, of course with the power/turbo u want to use a forged bottom end is pointless.

Can Gen2 gte pistons work in the ge block? The block is a gen3. Thank You i am getting closser to a solution.

its a 3s block, GE is the head model. gen2/gen3 BLOCK is really the same, just manufactured at a different time and reinforced in a different way, teh technical specs match. as forging over the years progresses they try to find ways to reduce weight with new spine methods

So thats a yes i can use the turbo pistons in the non turbo block. I wanted to turbocharge the curren so thats why i want the info. just give me a definite yes so i can know what to do lol. I like yes no answers lol. Thank You

yes

Thank You. and adding a turbo on the ge block with the gte pistons how much power you guys figure i can squeze out of it with a ct26?

for info 3s-gte pistons with a beams head will raise compression to something like 12.5 or there abouts, because the combustion chambers on the beams are about 20cc smaller.

food for thought but because a gen 3 3s-ge has slightly more aggressive cams than a 3s-gte if you work out the dynamic compression, at 11.5psi the 3s-ge will have a dynamic compression ratio almost identical to that of the 3s-gte at 14.7psi, and given the pistons in a gen 3 3s-ge are virtually identical bar the raised crown to the gen 2 3s-gte pistons, less boost is also easier to cool, so the threat of detonation etc might not be as much as anyone thinks, all theory though. If you have the pistons though better to use them for safety but sooner or later someone needs to turbo a stock 3s-ge

Thank You. That was some usefull info.....

or put 3sge cams in a 3sgte??

yeah you could but i'm not sure how that helps when turbo'ing a 3s-ge
