2GRE-FE swap

I have been reading up about the 2GRE-FE swap and just bought my car recently. Right now I am trying to get a hold on everything I need up front from all of the extremely helpful posts people have made so far.

So far I have a 92 N/A. And am waiting about 6 weeks for my engine lift to arrive so I can install it and start work. In the meantime I want to use this time to start gathering parts and prepping for it. I am considering buying a crashed donor car so I don't have to keep running to the junk yard, so that brings me to my first question.

After I get this running and reliable I will plan to add a turbo later. Is anyone running a turbo here with stock ECU or is a stand alone needed?

1) If I purchase a donor car is there one that is recommended as the best? It seems the wiring harness form the Rav4 works best?

2) Is there any issue having the donor car be an automatic?

3) Is it possible to keep the power steering or will I have to delete this?

4) I'll be using a E153 Transmission. I noticed I need a V6 Flywheel, can this come from the donor car I buy or does it need to be specific? I saw someone used a Camry 1MZ for one.

I have started a list of items below, any info you can add would be awesome of things that you would do different or recommend.

2GRE-FE Motor Verify imobilizer situation, seems there is a delete kit.
Change plugs/Belts hoses/Water pump
Check VVT oil line If rubber, replace with metal
4th motor mount
Alternator
Starter
Tachometer from 1mz
DBW pedal W/ Adapter
Need original Harness and donor harness.
Harness conversion
ECU Can take off immobilizer
Exhaust (possibly adding turbo next year)
Y pipe
A/C (including?) MK3 compressor? Might leave this off at first and add later
Intake
MAF
Water neck converter
E153 Transmission
Turbo Trans mounts
Turbo LSD Axles
Turbo Clutch pedal Option
Turbo Shifter Cables
Turbo Hubs
Turbo Brakes Option (are there bigger brakes easily available?)
Turbo Brake Master Cylinder Option (look at other brakes)
Turbo Brake Booster Option (look at other brakes)
255 lph fuel pump Supra TT pump
Alloy Flywheel Need a V6 Flywheel. Camry?
Clutch Southbend Stg 2 Endurance (495 ft lbs) as an option
Clutch slave and hose
17/18 staggered wheels Not required
BC coil overs Not required
Fuel system FPR and return line Aeromotive A1000-6? $300
Passenger Axle Carrier Use 2gr two piece or the 3sgte piece and slot the holes
O2 sensors in y pipe before headers merge?

0) Gouky's S/C tuned stock ECU might work for a low boost turbo setup - ask him.
1) Probably any 2GR car is OK if you're willing to source the RAV4 harness separately to get the cleanest ECU install.
2) They all are.
3) MR2's power steering is completely independent of the engine. You will remove the PS pump from the donor 2GR, if it has one (some 2GR cars have electrically assisted PS and do not have a PS pump on the engine).
4) Donor car will have an AT flexplate (not a flywheel). Must get a 1mz, 2vz or 3vz flywheel. But NOT a truck v6 flywheel.

Buying a crashed donor can work, that used to matter more when we needed to keep the immobilizer bits to get a proper car built but now that i sell a modded ECU without immobilizer the need isn't nearly as important anymore.

it depends what your horsepower goals are. I've got a tune that will work at 10psi on the stock ECU right now but at the moment there's no way to tune it yourself. if you want to go standalone you sacrifice some of the fantastic stock ECU drivability and engine protection but i'd be happy to help you with some starter maps if you want to go that way.

The rav4 wiring harness is much easier to deal with but otherwise there really isn't a preference as to which donor you use.

There are no factory manual applications for the 2GR-FE.

The MR2 uses electric power steering. you will delete the pump from the motor but the MR2 will retain its power steering.

you can use the factory 1mz/3vz flywheel or the lightweight fidanza unit that is available for those applications (PN: 130881)

The build list gives me a sense of deja vu. As if I wrote it myself. Wink.

Nobody has made one in an MR2 as far as i know. but the stock ECU is a MAF setup and should have no issues responding to a turbo instead of a supercharger.

This is somewhat off the subject, but how does the stock ECU enrich enough for boost? I mean, optimal AFR for NA is quite a bit leaner than it is for boost, and there is no MAP sensor, so how does it know it's in boost? Just based on VE over 100%?

The stock tune N/A ECU tune will only really support 1psi maybe 2psi of boost. it does not enrich for boost but since it does not really handle much boost it isn't the biggest issue anyways. the tune i'm talking about using for this is the modified TRD tune i've worked on. it can handle about 10psi (160% load) and does enrich as appropriate for boost. The tables are good to 10psi but i've only been able to check to 8psi since that's where the TRD/Lotus supercharger goes on my setup. I feel that the little bit of the tables that i haven't been able to cover are probably close enough for the ECU to learn/perfect from there.

Also, as far as the power output goes, the extra 2 psi should get an extra 20HP to the ground and by going to a turbo you'd gain back the 20-30hp that the supercharger takes to drive. The resulting output with almost no additional stress on the motor should be about 390rwhp (about 450hp at the flywheel)

Also, since the current tune isn't expecting intercooling once you cool the air charge you'll gain more overhead which would allow more timing in the motor. The current tune will learn extra timing in there within a reasonable limit but that said there may be some extra power with a bit more tuning once i get my hands on a turbo setup.

Thanks for all the replies so far, and answers. I am really excited to get started.

As merryFrankster noted I have read what feels like hundreds of posts to collect my list so I may very well have found yours too!! Thanks.

It will take me about 6-8 weeks before I can really start work but I plan to pre purchase a lot of stuff. My time working on the car is limited to about 1 day every 2 weeks so I want to be as efficient as possible. Gouky, I'll be reaching out to you once I get further along about using some of your stuff.

Once I have some updates I'll keep posting and I'll try to put up photos as I go. In the end I may try to paint the car myself as well (so it may look fantastic or really awful...)

That flare job is a little more complex than I am looking to do, but do you have an after painting photo? Great job so far.


I am starting to look at sourcing parts. The below parts are the first on the list if anyone has any please send me a PM. I have seen a lot of mis priced stuff online or just mislabeled so I am taking my time looking for them.

For the engine I think I'll be looking for a crashed RAV4 so I can get gas pedal/harness/ecu as well.

E153 Transmission (w/LSD)
Turbo Trans mounts
Turbo LSD Axles
Turbo Clutch pedal Option
Turbo Shifter Cables
Turbo Hubs

PM me if you have any of those parts.

Why in the world are you waiting 6 weeks for your engine hoist to arrive?

I got these parts mostly from facebook and eBay. There are some active sellers on the "Mr2 parts for sale or wanted" group. Note there are two versions of the group one international and one US. Post a "WTB" there and you should get responses quickly. Use paypal and pay the product sales fee it's worth it in case there is a dispute or delay. On eBay there are some JDM importers whom I also had good luck with.

The mounts are becoming scarce. For the front mount on the firewall there is a third party mount available cheap.It is not the greatest quality but you can re-inforce it with resin if you desire. I think mine may have already broke already even with the reinforcement. The front bracket that goes with this IIRC is same as NA. For the top transmission mount you will also need the bracket/plate that mounts it to the trans housing. I had to source these two items separately. The rear bracket is difficult to find, and so is the mount. I scoured the internet or days and days before I scored these separately. Maybe you can find a transmission that comes with the brackets attached.

There are a few pictures around, on my website and else where. It has been running / driving for about two years since the paint job now.

So I am trying to narrow down what 2GR to buy. I found a transmission I am considering buying and just getting some photos and background on it now.

Any advice on what year motors to look for. I read one of Gouky's old posts saying that the Highlander motor w/ the oil cooler is a good start. Any other advice? Is there certain years that work best?

I have been looking at the motors seem to go for 2-3.5k which I felt seemed high for a motor where there are so many available, is this just the going rate? Or should I look harder.

Also any advice on a clutch for daily driver / weekend track. I either will put a turbo on right away or within a year and run ~10psi so 400-450ft lbs.

If you are going to build the motor or tear it down and refresh it I would go with a cheap one. If you dont want to touch anything before you drop it in I would go with a 2010+ where they have fixed the leaking timing cover, bad coils and vvti line already. Also beware the early oil cooler lines are prone to rupture at higher mileage.

When I was looking there were lots of options in the 1500-2000 range. I ended up paying $2000 for a 2012 motor with 30k miles, with a few extras included.

Not sure what to do with that torque level, but I really like my Southbend clutch. I was using it on my ~375whp 3S before sending it back to get refreshed for use on the 2GR. But that was under 350ft-lb peak.
