I thought of creating a post to keep me motivated on my project for 2GR.
In my country, nobody has done the 2GR swap into their MR2. Therefore, my only reference was through reading from the forum and Marc youtube channel.

I read so many comments on the reliability of the 2GR motor, so I dare myself to take up the challenge. I have done a lot of planning. The project has already begun, and it is still ongoing. I planned to have it run with Link Xtreme G4x with Link Lambda sensor and PMU16 from ECUMasters.

I plan to replace most of the relay and fuses with the PMU16 from ECUMaster. After all, our wiring is already past 25 years old. I also find that power management to be more efficient and simpler to manage via its software. I am still in the learning process on the PMU16, but I guess I am kind of getting the hang of it. Thanks to the HPacademy, I got a steep learning curve. I can share my pinout PMU16 management if anyone here finds it interesting.

I still have not reached the wiring stage yet. I plan to have the battery located just behind the passenger seat as I don't really see myself utilizing that compartment for the OEM Subwoofer. I plan to have the LINK ECU and the PMU16 located near that compartment. The idea of having the battery located is to have it nearer to the alternator. I also plan to have the Kill Switch situated near the battery. It will be an easy reach for me to the Killswitch with that location. However, I am also contemplating on this idea as to whether I should proceed to just leave the battery at its original place or have it located in the proposed compartment. Of course, a lead-acid battery is a BIG NO having the battery located in the cabin. I would have to then resort to at least an AGM battery instead.

The dashboard was taken out to have better access for a wiring job to make life easier. I have also gotten myself ready for a digital dash to connect it via CANBus to my ECU.

As you can see, my dashboard is all taken out. I guess, with the PMU16 on its way, the wiring will be much more straightforward to begin with.

I could see that I am going through a massive job. It is as good as rebuilding a car. However, I can only do as much planning as I can at my level. Therefore I'm pretty selective of whom I send my car to. Most of the execution is the effort of those who are good at what they are doing. I am fortunate to have them advise me on the planning and execution. SPV Automotive will do the mechanical part and the wiring part; RNR Autosport is the one who will take the job.



I believe this project will take time to complete. However, I hope I can keep my motivation up to a point to see my car complete.

Huge undertaking with a lot of money spent and yet to spend!

I am excited to see where this goes, great progress so far

Don't forget about lithium batteries for you relocation project
I am more inclined towards AGM battery. However, that will be pretty much decided once I get the car wiring all ready.

There are some pros and cons to having the battery behind the passenger seats.

As of now, to get the 2GR motor into the car. Being a right-hand drive car, I have bought the DBW pedal from Paul Woods. We are lucky to have him in the MR2 world.

There are times I feel like giving up. Rebuilding a car sure needs a lot of patients and passion. But, a lost motivation can also lead to an abandoned project. That's the reason I made this thread. Not sure how long I can keep my motivation up.

Ive been building my car for the last 7yrs, pretty much since the day I bought it. All things take time, and I get distracted with painting my Tahoe, engine swapping my Corvette, building my Ranger, working on the house, tracking the bikes, building mountain bikes, sleeping in, hating winter- you name it

Life has a funny way of slowing you down. Just pick a target and get a little done every day. The only one in a hurry is you, and you determine how much of a hurry that really is. An hr here and there adds up to a lot of work performed in just a week

Focus. Execute.

I think you can do this!

Edit: Re: Dash- did you 3D print, or otherwise mold the dash insert, or is that a part you found for sale somewhere? I need to do something similar for a BTI dash in my car

Having the 3SGTE engine out of the engine bay gave the opportunity to respray the engine bay. I chose to spray it with the same body colour. Oh yeah, the paint shop has sprayed the absorber head as well..grrr..early inspection seems it doesn't affect the adjustable soft/hard mechanism.

Next up is the flywheel. The 3SGTE flywheel won't match it. Its a Fidanza Flywheel. This the early stage of installation

Thanks for the motivation.

As for the dash, there is various online seller nowadays selling it. You can try to get it at Mako Sports.

Engine bay looks great but they sprayed the strut bolts too! 😂 Not really a problem, you'll just tear the paint off when you have to undo them. Great to see progress, keep it going!

Gosh I love seeing an empty engine bay and how much space there is in there before adding all the turbo bits.
Im envious of the situation, it'd be nice to 'start from scratch' and be able to route things as you wish, hide this and that/wire tuck it.
Please, keep the pics coming, love seeing this progress

Getting the engine into the engine bay has its challenge, but the job could be done with more minor complications thanks to Marc's mountings and some adaptors.

The work has been done carefully by SPV Automotive. Even they learn a lot on this swap. There is a lot of discussion going on in this process of getting the engine going in.

I find that the engine seems to have more room compared to my 3SGTE. Maybe my 3SGTE is packed with its water-methanol setup and intercooler. Or perhaps the 2GR is far from being complete. The picture below is a comparison between the 2GR and 3SGTE Gen5. Any comments on this?

Great progress but I see a missed opportunity to clean the engine up before install, paint valve covers etc.
We did do some engine clean up but not as details. I plan to get it clean during the final stage when all the wiring and mechanical setup have been put in place. I feel that doing it now won't be as effective as this project may drag up to 6 months or so

The mechanical progress goes as planned. After getting the engine in,,,, it's time for the exhaust installation. It starts with the header. I am not using back the OEM Header. Below is the comparison of the OEM Header vs custom

As for the exhaust piping, I am amazed at what @Alex W wrote about X-pipe Dual Exhaust. Therefore I wish to follow-suit the idea but with a bit of change on the exhaust outlet. Instead of a dual centre exit, I go for the OEM dual exit (left-right) look. I kind of like the way it looks. But this design got its bends and turns.

This bend seems low, but it looks similar to how @Alex W did. This is the furthers up, and I can go. I don't plan to make my car as low as possible and make it similar to OEM look. I hope it doesn't scratch anything at this point of the bend.

This is the X-Pipe design. Looks smooth and neat. As I mentioned above, this design will have the pipe exit left-right just like the OEM looks.

As u can see, I don't use Borla exhaust as @Alex W did.
At this moment, the car still has not started yet. So I have no idea how the sound likes and what horsepower and torque it churns out.
This kind of work sure takes its time. Got to be really patient with it. I believe I will be undergoing minor touch-ups of this setup once the car is tuned. But, I let it be this way as I need all the appropriate positions for my wiring routing.

Ahhh, the Wiring will be the most challenging part. Most of the time spend on wiring planning.

Not much progress going on now. Just some wiring cleaning and checking the old connection. However, I have some change of plan on the dash. Therefore I am letting my digital dash cluster go with its meter cluster. If anyone is interested, just let pm me, we can negotiate a deal.
