Looks like it will be a great project! Interested to see how you go with the 240 front brake conversion. Another guy in our club has been working on that as...

So quite a lot has happened since I last posted.

I've finished the wiring in the engine bay. The engine and car are still on separate looms so the engine setup can be put into something else or the car can have a B20 put back in very easily.

I've also started on the interior wiring where all of the cars wiring is now tucked out of the way ready for the corollas looms to be put in. But i'll probably test start the engine before that.

After doing all the front end wiring i chucked a battery in and i couldn't get anything to work.. No lights, no power, nothing... After thinking of the worst things possible i moved the ground and everything lit up! I was about ready to burn the thing to the ground.

The oil system is finished. I tried to make a neat package that is hidden and not a total mess. The setup is very modular and free flowing. The cooler is placed just behind the air intake on the bottom lip, so it is also functional and it will put a little more weight over the front end.

I'm a bit worried about the weight, if all the numbers on the internet are true ill be way too light in the front, and there isn't much that can be taken from the rear, the boot can be skinned and things like brackets etc can come off but there isn't much else. I came up with a 40/60 split taking into account all the weights i've found online for the 142.. I really need to corner weight the car to see exactly what it is.

Made a new belt and pulley system. I got a 6 rib pulley for the tensioner arm. Most people will use an idler off to the left, but i've got a steering box there.

Plenum is now finished. I used a 4g63 plenum and cut and modified it to fit on the 2zz flange and throttle body. I chose this plenum and it matches up with the 2zz fairly well, has bellmouths for each runner, the shape, and it's not absolutely massive like others. Everything follows another line so it looks like it's meant to be there.

The only other thing to do is to fill it with oil. Do the fuel lines. Plug everything in and start it.

I'm a bit anxious about it because I've done so much wiring on the engine and haven't even plugged it in to make sure it all works.

Updated pics from page 8.

Nice work. Guess you could move the battery back to the front? ?

I'm surprised your weight distribution would be 40/60. When we did the EV conversion on the 240, even with the much lighter motor and adding 240 kg of batteries and components sitting where the rear seat was, we're still around 48F/52R. Yes, weigh corners to confirm and maybe you'll be pleasantly surprised.

I based it off 1050kg. So the lighter the car the more the weight affects the balance :)

Battery location is still up in the air, i had thought about the front pass side compartment, or just get a light battery.

It will have to go on the scales once i'm up to the battery location and finalizing the interior wiring. I'm pretty fixated on the weight and balance of the car, but i guess at the end of the day it will jut affect my driving style when really pushing it..

Yeah guess the only way to know for sure is to weigh. I did a fairly comprehensive spreadsheet and measured each component's location and weight when removing and adding bits, and came up with a fairly accurate result - I think I was off by about 1% one way or the other and about 50 kg all up. Where'd the 1050 kg come from? Is that with the new (and presumably lighter) engine? I would have thought a standard 140 would weigh around 1250-1300 kg given a 240 is around 1350 give or take...I could be way off and haven't Googled it LOL! :)

Yep 1050 came from added parts and removed parts, engine and trans combo, wiring, etc etc everything.

The weight on google and a few forums have said around 1150-1200kg for the 142 with b20 twin carb. I'm relying on the internet and workshop manuals to be correct for the 2zz and 142 balance, then obviously adding in the other parts and their locations. I had a very detailed spreadsheet too, But i guess there is only so much you can do with pen and paper..

As i said above, i think i'm just too fixated on the weight of things. It will be almost impossible to get an accurate measurement of balance without having exact data while taking into account how far forward or rearward that weight sits.. Time for scales.

Wow I didn't realise how much heft the 240s put on over the 140s...that thing will be a screamer! :)

Even the express was registered as 1200kg.

Thats the other thing lol. There are so many differences between each year and in each model too.. The rear suspension being different in the early 140's compared to late, whether you have the auto or manual, power windows, differences in under dash brackets, heater controls, brake crossbar. Theres so many variables.

I know with 240's its even worse. Americans have those crash triangles and so much added bracing throughout the car. among other things

In my experience, published weights are usually less than the cars actually weigh. The Europeans seem to be slightly optimistic, the Japanese can be very optimistic.

I can’t see this thing being too bad for weight distribution once it is finished.

It runs. Not sure how to post a video on here though. So here's a picture under 10mb instead.

I don't have much to say other than congrats, and really neat job with the swap. Excellent choice in engine too! I'm sure this will be a massive hoot to drive.

Edit: You can upload a video to youtube, mark it as 'unlisted' so it's not searchable (or not, doesn't matter either way), then just copy/paste in the URL to the video into a post, and it'll automagically embed it into your post.

Thanks mate :) I'll try and give it a go.

I posted a video to Instagram and the iroll Facebook page

Wow that exhaust manifold is a work of art! :)

I didn't make it haha. The plan was to make one but this came up at a great price shipped from USA

Congrats! Looks great

So awesome. Well done!

You can just post a link to the insta post here also, it should turn it into a video (I think)
