?'s about rebuilding

[H-Dogg]

I need new pistons and I've got some people telling me I can use the 2JZ's in my 1JZ but I've got others saying I can't! The same is going for the connecting rods and crankshaft. I'd like to get all forged internals but don't know what to get because I'm not sure what will work, any clarification would be nice. Thanks!

2JZ pistons should work


but a 2J crank and rods wont work in the 1J block iirc

from what i know ^ he's correct, pistons yes, crank & rods no due to displacement. 1j rods are tiny compared to 2js.

Alrighty, so I could use 2JZ forged pistons and JUN makes forged 1JZ connecting rods, but does anyone know where I could get a stronger crankshaft?

Ok, CP pistons for the 2jz are the same dimensions as the 1jz, tim from sound performance had a thread about them, Rods.... you should befine with the stock ones, you can use some ARP rod bolts & make them stronger, Crank...
i doubt you need a aftermarket one, if you want displacement get a 2jz short block.
