1JZ Pistons

I have a friend that was trying to use 2J piston rings. This is what he found . . .
He said that only one ring fit or something. All I know is that they don't fit and you should not open your 1J unless it is absolutely necessary cuz 1J piston rings are super hard to come by . .. werd

PS: This was one of the reasons I went with the 2JZGTE . .. that and torque (Daily Duty).

Correct butt you can use aftermarket 2JZ pistons for the 1JZ Like CP JE etc etc
Iff you need like 1 piston and the rings for de 1JZ Then you have a problem very hard to find (rings)
some people claim that 86-94 3S-GTE use the same piston rings s the 1JZ butt nobody ever compare those rings
Size is the sam of the 3SGTE (1.2,1.5,4.0mm x 86mm)
Most people just putt an 2JZ blok and make it an 1.5 JZ :icon_bigg
lol, you're spot on with all that. 3GSTE are "apparently" though .. . it's also my friends last ditch plan. I will remind him that he could just use 2J pistons.
Since none of this has to do with me and I am relaying said info, may I ask what CP would 2J pistons yield in a 1J block?

The 1jz pistons have different ring lands and also skirts are shorter then the 2jz oem pistons. You can buy a aftermarket piston for a 2jz and use it on a 1jz block.
ok im that person that found the rings dont fit......so the compression height of the 1jz pistons are 1.338" exactly the same as the AFTERMARKET 2jz pistons!!! sooo after taxing out my resources to allocate rings for the 1jz, ill just save 2 pay checks to buy some forged slugs......since im uping the boost need to be extra safe.....thanks jacob for the help!!!!!!!!
said is one thing, knowing 100% is another....thats how i found out about the 2j rings not fitting.....i heard they did, but know one actually tryed them. so i need to know 100% with pics before i buy...
You can fit the 2jz pistons on the 1jz but they will have to be made for the n/a 2jz and still the compression will be lower than with the stock 1jz pistons. Don't even think on using turbo 2jz pistons on your 1jz. I compared the rings of the 3sgte engine and they will fit on the 1jz pistons. I hope I wasn't to late.. Good luck..

Tim used to work for Sound Performance, He posted the info here about the CP pistons for the 2j been identical to the stock 1jz, As in size & where the ring lands are & all the rest of the info you need, I can not find his damn post lol... my search skill sucks.. :cry:
hahah thanks guys....im haveing the block cleaned and checked out @ a machine shop...so before i buy i need to make sure the block is ok. as for using 2jz pistons i wont anymore....its only 100-200 bucks more for a set if custom made 1jzgte pistons...so ill get thoes if need be.
