Installing a Stock Aristo 2JZ-GTE VVTi JZS161 Engine into an S13

Engine install

Getting the engine into the car is not a big issue, the engine is physically bigger and you lose about 4 inches between the front of the engine and the radiator (comparing to the SR20). Having a “larger” 2-ton hoist and a leveler helps with the process of installation. I am using the Xsessive conversion mounts with Cusco motor mounts(originally for the SR20) on this swap and because they are slotted, it is very easy to get the engine in place. Using this mount combo did cause the engine to sit higher than normal and required the hood to be cut. Using these mounts I was able to get the engine to site right on the firewall. This is something that you want because it will get most of the weight farther to the center of the car for better weight distribution

Wiring

The wiring for the car I tried to do in the simplest way. I first found guides that explained the wiring on how to get the engine running outside of the car ( a great example of a 2jz running without a car: https://www.youtube.com/watch?v=EDkwW0gQW4o). With wiring the main Powers and the and ground (e.g  IGSW, +B, +B1, BATT) I was able to just have a power and a ground (and another power for the starter) to get it started. From there it is as simple as wiring in a car stereo.

Also, William made a great write up if the ECU pinout and diagram: http://wilbo666.pbworks.com/w/page/42173082/2JZ-GTE%20VVTi%20JZS161%20Aristo%20Engine%20Wiring

Issues

Power Steering issue

The OEM power steering pump on the JZS161 Aristo has an Electronic Speed Sensitivity control (not the official name). This motor can be seen the on VVTI pump itself below (picture from 2jzgarage.com)IMG_0155

When bolted directly onto the S13 the power steering system the steering feel is very inconsistent. After looking at both a VVTi 2jz pump and a Non-VVTi 2jz pump, I pulled off the VVTi PS pump pressure control motor and installed the non-VVTi intermittent plug. After doing this the power steering worked perfectly.
