Plan to do engine swap on my celica 82. change the 21R engine to 1jzgte.

The Gurus, the experienced and the wise. I know there are many of you here in this group. please lend me your expert opinions.

What problems I can expect.?? Is it too heavy for the chassis ?? car stability ?? Those who had it done before or considered it before can
shed some light here. ANy wiring problem ?

AS many knows, the celica 82 and mk2 is same from firewall to the back.

Many thanks :D

i think your biggest problem is going to be space, although ive never even owned a celica, nor a 2jz, so i might be wrong, but as far as i know, its a snug fit in the celica supra, so it might be too big an engine for the celica.

itll probably also kill your balance and handling, although you might be able to use celica supra struts and springs to restore the nose suspension to something normal.

if i were to swap an engine into the celica, id look at the 4agze... supercharged goodness :)

It can and has been done, but is it worth doing? Not by a long shot. The Celica engine bay is much smaller than the Supra, so fitting that big inline six in there (and 1JZ's are BIG) is a fairly serious undertaking. As has already been mentioned, handling and chassis balance will suffer as well. On top of this you'll be stuck with the small open diff and live axle found in your Celica - in other words, you'll have huge traction problems until the diff shatters into a zillion pieces (which will take about a day with the torque of a 1JZ).

So why make all these compromises when you can trade your Celica for a Supra? The 1JZ fits like it was meant to go there, handling/balance is not affected (JZ engines are actually slightly lighter than M engines), the drivetrain can cope with the torque, and you'll actually be able to get the power to the ground. On top of this you get all the extra goodies that come with a Supra - P/S, A/C, IRS, 4-wheel discs, 14x7 alloys, nice seats and generally better interior, the list goes on.

In summary: if you want a JZ engine, get a Supra first. Take it from someone who's done it! :)

3000cc MK2 said:
I would suggest a 3SGTE engine for the celica
Thats what I was going to suggest, a 3sgte would be perfect for one of those celicas. Its been done before too. I belive toyota has made a 3S to w bellhousing as well, the Euro and Japanese Altezzas and IS200s should have them, not to mention a 3sgte to boot. The 3s has been around since the 80s, shouldn't be a problem tracking one down, but try for a newer one, like what came in the last years of the SW20 (turbo mr2), 250hp from the factory.

Actually the 3sgte would be an awesome swap for a mk2 as well, if anyone here could get over the whole 4 cylinder thing. I know I can't, I like my i sixes :D

A RWD 3S-GTE is a great idea but it's not easy (or cheap) to do it in practice. For starters there has never been a factory RWD version; the JDM Altezza (aka IS200) comes with a 3S-GE and there is no turbo option. You also won't find a W5x bellhousing in one of these because they come with a 6-speed. And besides, being a late-model engine they're pretty expensive.

Having said that, if you can afford it it would be pretty sweet dropping an Altezza engine and 6-speed in a Celica. :)

Thanks for everyone inputs.

Its good to know that somebody has done the swap before at toysport.

I had thought of 3sgte before , Its difficult to find a RWD front-cut . so is 4Age. Corect me if I am wrong.

SR20DET is perhaps excellent for the celica. I know someone who did this. Somehow its hard to swallow for some people to see nissan Engine inside Toyota or vice-versa.

1JZ is smaller than 2JZ. correct me if I am wrong.. 1JZ fits inside the Celica Engine bay, but rather tight.... .

I can summarise potential concerns ...

1. Engine space
2. Handling and balance
3. Live axle concern...


Well the plan is to remove the hydarulic fan off the engine and use electric fan in the front of Radiator (outside the bay ) , to gain space in the engine bay. hack a little of the firewall to move the engine slightly to the rear , to gain space and perhaps improving the balance.

We have to think of something regarding the axle. Perhaps use it for a while to see what problem..!!!

I have both the Mk 2 and the celica. I would like to get the celica done first , it is moving like a snail now, with only 100 odd horses....with 21R engine.

Re: the handling problem & the 1JZ.

The 1JZ physical size of the short block is still roughly the size of the 2JZ (having seen pics of them side by side). Only difference is the 1J is a 2.5L, the 2J is a 3.0L.

Regardless, installing a larger/longer motor into a chassis that has a SHORTER wheelbase that was not designed for this motor is really going to HOSE your weight distribution up front. You'll probably be fine if you plan on going in a straight line, but if you're going around twisties... eeek.

Yes, installing it can be done, but the results in the end... :p

Yeah, what he said. The 1JZ block is about 25mm shorter than the 2JZ, but apart from that the external dimensions are the same.

I still think you're nuts for considering this; engine conversions are hard enough as it is, so why make it harder for yourself? You have a Mk2 so put a 1JZ in that!
