Toyota MR2 Message Board - View Single Post - Other 2ZZ-GE Engine Swap Info

Write up for installing 2ZZ-GE with C-60 into MK1. If you choose to use an alternate transaxle, you will encounter other variables. Ill try my best to remember everything and add part #'s where applicable.

1. Mounting Points- All 3 transaxle mounts can be used from the C-52. Some fab work is necessary for the passenger motor mount.

2. Evap/Fuel system - make returnless, somewhat extensive
*check the other board for write-up with pics on making a return system returnless*

3. Slave cylinder - minor requires 3/16 female to male M12 coupling (brake fitting) From the firewall chassis fitting to 3/16" aluminum brake line. Use tube bender to make custom bends. Attach to the C-60's slave.

4. Header - reweld flange or contact David Lee (LittleRocket) who sells Brad Bedell's header. I custom frabricated my own B-Pipe. Bedell may eventually have a B-Pipe available.

5. Axles - 91+ MR2 N/A non-ABS

6. Power Steering Pump removed - 1ZZ Idler pulley PN:13570-22010

7. Coolant/Heater hose - custom setup, many ways to do this.

8. Clutch selector cable bracket - Moddified C-52 bracket to sit higher on the C-60

9. Transaxle Mod - Note: I used a transaxle from a JDM Fielder which is like that of the Matrix/Vibe. I had to reverse the select lever to exit the front of the housing. Using the Celica version does not require this mod. PapoJ rotated the selector lever 180* to match the cables, but used a C-52 bellhousing. This allowed for him to use the C-52 cable bracket in the factory location. I modified my C-52 bracket to sit higher like it did on the original transaxle. All internal springs, clips, select levers, etc. were swapped from the Fielder's select lever shaft to the Celica's version select lever shaft.

9. Dipstick and Tube - MRS 1ZZ
- some minor tweaking was required to get it to fit.
Dipstick PN: 15301-22040
Guide(tube) PN: 11452-22040

10. Fuel Line - filter to fuel rail. I cut banjo fitting from the fuel line of the 4AGE where it mates to the filter and the quick-connect from the 2ZZ fuel line where it attaches to the fuel rail. These fittings were already barbed and inserted into 5/15" fuel injection hose. *Dont Use Fuel/Evap Hose* Its not rated for the higher PSI. Hose clamps should be used as well. 1 hose to connect the 4AGE filter to the 2ZZ rail.

I still have my notes and the JDM Pinouts(wiring diagram), Connector Chart and Fuse/Relay Box for the early version of the Fielder/RunX/Alan in PDF format. Extensive...

This is how I have wired mine thus far.

I used the molex(N1) in the trunk and M1 and M2. I picked up mating connectors from the salvage yard. These were mated to coresponding wires of 2 of the ECU connectors, engine harness connectors and the added fuse box.

I used the fuse box from the Fielder to incorperate other fuses and relays. One of the relays was made the C/Open and also used the EFI relay and fuse for the EFI system. Unused fuses, relays and associated wiring were scrapped.

I basicly used the MR2's fusebox to run some of the components intended. The Fielder's box was used to supply power to parts of the system I didnt think I could reconfigure. I was basicly trying to wire the 2ZZ as the engine would have originally been wired, basicly for OBD2 purposes.

The two systems are wired differently and being that I am no expert tried to do this in the most simple fashion for my understanding. The principles between the two systems are similar, but routing is different.

On a cpl of other notes, this being an OBD2 system, it only has one O2 sensor. I found this suprising, but I guess there are different regulations in Japan.

The Celica's pinout indicates 2 O2's where this system only has wiring for 1, which splices into the OBD2 port. I also have the Fielder's exhaust and only 1 4-wire O2 sensor came with it.

The OBD2 port will be in my trunk as opposed to under the dash.

The only thing I havent figured out how to wire up are my oil sending wire, water temp wire and the VSV for the evap. (4age sending unit tee'd into the oil pressure selinoid next to the oil filter. Coolant temp sending unit yet to be installed. I have thought about the blocks drain-cock, but unsure.) I have one plug in the new system I dont have all the pinouts for and Im sure it mates to the oil and water. (I Found this to be incorrect. This connector had wires for the charging system) Im also under the impression that the Celi evap I purchased may be different than that of the JDM version as this schematic doesnt cover that VSV. The Celi's did cover the wiring for it. This is something Ill have to work around or reconfigure once Im up and running.

I will fix and/or add info as I remember or locate it.
