Snailed Posted July 24, 2012 Share Posted July 24, 2012 I plan on installing a non vvti 1jzgte in my Z but I may be able to use a 2jzgte to mock up my driveline angle so I can keep building as I save up for the swap. I read on supra forums that the crank centerline to deck on the 1jz is about 30mm shorter than the 2jz which makes sense and by pictures looks about right. Other factors would be head and valve cover height. Anyone have a non vvti 1jzgte they could measure for me? I'm concerned with hood clearance as I will probably have the engine mounted 2-4" higher than the typical 1jzgte in a 204z and would like to avoid modifying the hood if at all possible. Any help would be great. Thanks! Quote Link to comment Share on other sites More sharing options...
Fuzzydicerule Posted July 24, 2012 Share Posted July 24, 2012 I believe the 1jz is about 1/2 an inch (14mm) shorter than the 2jz Quote Link to comment Share on other sites More sharing options...
Snailed Posted July 24, 2012 Author Share Posted July 24, 2012 I believe the 1jz is about 1/2 an inch (14mm) shorter than the 2jz ok, so the head and valvecover on the 1jz may be about 1/2" taller than the 2jz? Here is a picture of the two side by side. Looks like slightly over an inch, no? Quote Link to comment Share on other sites More sharing options...
Fuzzydicerule Posted July 24, 2012 Share Posted July 24, 2012 I don't know for sure, that's just what I have seen documented. ( in te how to guide sticky on this forum. He mentions a 14mm height difference Te difference in stroke is only 14.5mm, I doubt they would add almost double that again to the height of the block Quote Link to comment Share on other sites More sharing options...

I would expect the valve cover and head heights to be different too... If I can get within 5mm or so that would be fine for what I'm trying to do.

Sketch_hs Posted July 27, 2012 Share Posted July 27, 2012 (edited) Hello, The 1jz engines are about an inch shorter than the 2jz engines. They are also a bit lighter, the 1jz vvti engine being the lightest of the turbo jz series engines.
