Diesel swap and restoration progress

[Petros]

I thought I read in one of the threads that the Tercel4wd came with a diesel option in Japan, but that could have been the later version.

If both have the same bolt-up, I would go with the bigger one. There will not be a lot of economy difference (your power output at cruise would be the same, the drag on the car is the same at the same speed with either engine). You will not regret having more power when it comes to a diesel, they tend to accelerate real slow anyway. Of course the one you find may determine which one you install, so it may be a moot point.

I could not get either of the picture links to work. You might want to repost them.

Ordered the 2C-T today. will be here in 30-45 days. total cost including shipping = $1895.00

WOW !
Good luck!

The 2C-T is On shore, fully paid for,has been shipped out and should be here within the week! Pictures are of my actual engine.

Very cool! How much does that engine weigh?

[CathodeRayTube]

no idea...im pretty sure its got a cast iron block and aluminum head...its a 2.0 liter. im planning to upgrade the suspension and do a slight (2 inches or so) lift somehow also...

[splatterdog]

Wow! Not only going to be the first T4 diesel, but turbo too. Your trans is going to hate you. haha

Did it come all the way from Japan?

Looks like power steering will be eliminated. Might also have to find a longer radiator that takes up the a/c side to keep it cool.

Add that to the list....

Im planning to drive very conservatively, and also add some other things to the tranny possibly...oil cooler, synth oil, possibly an extra pump to keep oil flowing over the top input shaft parts at all times...or if i end up burning it out then i have 2 spares...one with only 50k. and possibly have the spare pre treated and hardened/rebuilt before installing it as i read was successful with the 4age swap whoever did...

Yes it is all the way from Japan. I believe the PS pump is installed directly infront of the alternator as a compound unit...if not then i will figure out a way to add it on. im determined to keep all my accessorys. it does have an AC compressor. there will also be a top-mounted intercooler, wich will allow fresh air to be blown down over the top of the engine and out from underneath.

Hopefully it will fit in and bolt up...im still only about 80% sure it will...not really any other options other than winging it and seeing for myself. if it doesnt il be re selling it to somebody with a toyota van...and then rethinking the whole project. but shit-canning is not an option!

If using an engine driven P/S pump becomes difficult, get a last gen MR2 electric PS pump. Then use a PWM speed control to dial in just the right steering boost for any given condition. Just turn it off on the highway to get even better fuel economy.

Last time I checked, NAPA had the MR2 electric P/S pumps for under $200. Wreckers often want more for a used one. They seem to be a real popular item for those putting power rack and pinion steering racks into custom hot rods.

hell that sounds like a better solution even if a belt driven PS pump would fit fine. could probably rig it up to shut the PS off above say 25 mph automatically...probably would be more efficient.

Are you planning on running the stock 4.1 ratio diffs in that '86? I'm thinking that the 3.7 diffs from the '83-'84 t4wd might be better with the much slower revving diesel.

[CathodeRayTube]

i think the 4.1 will be fine. the diesel wont really rev much slower than a gasser...they have that reputation because large truck diesels DO redline at around 2k...but small ones like this should be very similar to a gasser. i never go over 4k driving any of my gas vehicles anyway, and my corolla sits at around 3k doing 70Mph on the freeway...

Should be OK as I just found this: The 2CT is indeed a Camry engine 2L TD, 83 hp @ 4,500rpm.
I'll bet that 4,500 is pretty much the max rpm. However, if you are looking at max economy, the 3.7 gear set might be the way to go. I'd just see how it drives & how much fuel it uses.

[CathodeRayTube]

Iv read that the higher gear ratio of the older tranny causes more internal stress on it...thats why i think the lower 4.1s would be better...but i may put slightly oversized tires on it so that may even things out...i suppose i could switch things around. im planning to buy another whole 1984 spare junk car that has the 3.7s...if the guy ever gets around to unearthing it and letting me know...

With the top mounted cooler, might I suggest a WRX scoop?

If you want to cool the trans you will need a pump to circulate oil to a cooler. You could definitely feed it back to the input area.

It will be nice to see mileage on your rig. Taller tires are always in order on any 4x4 in my book. I wouldn't worry about the 4.10's. It does reduce stress on the trans itself. Law of the lever.. Taller tires do help offset that though. 195/75/14's take about 200 rpms off at cruising speed. In a tercel that also adds amps to your radio. Synthetic gear oil is standard as far as I'm concerned.

Keep us posted!
