I was just curious to know the stroke/bore of a 1jz vs a 2jz
I found this
DESIGNATION TYPE SERIES CC. DISP. BORE STROKE HEAD
DOHC 1JZ-GTE 90- 2491* (280) @ 6200 269@4800 86.0 71.5 8.5:1

DOHC 2JZ-GE 95-96 2997 225 @ 6000 211@4800 86.0 86.0 10.0:1

DOHC 2JZ-GTE 97-98 2997* (280) @ 5600 335@3600 86.0 86.0 8.5:1

Product Stroker Kit Part # 1029M-T002
Bore 87.0mm Stroke 90.0mm Engine Disp. 3210cc Compression Ratio 8.5:1 *1

What would be the gains between them? What would be the better choice? 1jz internals in a 2jz block or 2jz internals on a 1jz? I am just wondering if any has done it.

 

whats the point??? Just use a 2jz block and internals.... You cant go wrong with more displacement. Find a cheap GE short block and if you want lower compression stick TT pistons in it. IMO 1jz bottom end is disposable, if it goes bad its a waste of time trying to fix it when a 2jz is better and easier to find.

 

The point would be just like some of the VQ engines out there you are able swap internals and make a stroker engine
