What do I need to look out for in the conversion?

You must have a front clip or it'll take you many months to sort things out.

Assume you have a mkiii front clip (not any other)and putting it in another mkiii 7m.

1. Be prepare to buy two new engine mounts (not used)
2. As stated By "Celicamad" Do not cut or loose anything from the clip.
3. Download the 1jz wiring diagram and look at http://www.supras.nl for more wiring issues.

If I was going to swap engines (not put another 7MGTE in) then I'd swap the computer over at the same time. So wiring won't be a hassle in that regard (yes I realise it'll be a sh#t fight when I do put in another computer anyway).

So at the moment I'm just talking physically put the engine in.

Physically bolting in the engine, not including inlet plumbing and ancilliaries, shouldn't take any more than a day if you have access to the proper equipment (eg engine crane).

If you doing a 1JZ-GTE into an MA/GA-70 you are up for a reasonably large job. You will need the cross member off a JZA-70 for the 1JZ-GTE sump to fit.

You are likely to need the Rack and Power steering setup off the JZA-70, as well as a lot of other stuff.

Hope some of this is useful info. Sounds like your doing the conversion I should have done.

Following Norbie's comment. I may be able to help you out with an engine crane. I have one. Unless Paul SUPRAGTE is using it to pull his GTE. I offered him first.

Re: How long would a conversion from a 7MGTE to a 1JZGTE Thu, 12 September 2002 03:02 Go to previous messageGo to next message
I found out a couple of weeks ago that my engine wasn't the best, if you've been following other posts, my no 6 cyl was leaking 74%.

I put my car in to get the turbo fixed (leaking oil). The turbo has 10mm of play in it and has eaten away at the housing. $2,600 to get it fixed (Garret T04E).

So instead of beating the dead horse, I'm considering putting in another 7MGTE over the weekend, or doing a conversion to a 1JZGTE (cheap) or a 1UZ (which I'd like to twin turbo at a later date).

Meanwhile I don't have a car (have got someone looking for one in the auctions today, $200 with 2 or 3 months rego I'm hoping for).

I Think I'd prefer the 1UZ if I was going to do an engine change. Or I might just put another 7M in to get it going again.

This is only true if you have a pre-89 Supra. 89+ models have an updated crossmember which is identical to the JZA70.

Its a '91 GT. I'm currently thinking of just going for a 1UZFE, then later twin turboing that.

My latest problem with the 1UZ is the gearbox. My car used to be auto (someone has converted it). Now to convert the 7MGTE from auto to manual, would they need an adapter plate? Can I use the same adapter plate on the 1UZ? What gearbox do I need where can I get one from and how much? Who can make an adapter plate for it (if I take in engine and gearbox). Apparently there is a good gearbox place around Milperra (not far from my place) anyone know who this is?

You don't need an adapter plate for a 7M, you just need a manual transmission from a 7M (ie W58 or R154).

There is no factory manual transmission which bolts up to the 1UZ. Dellows and Castlemain Rod Shop make bellhousing kits for the W58, but the torque of a 1UZ combined with the weight of an MA70 will shorten its lifespan considerably. Add forced induction and its lifespan will be measured in minutes.

Where abouts are Dellows (can't find their number/address)?

I'm not sure what gearbox it has, where would the gerbox id be located?

Not sure about Dellows, but you can find Castlemain Rod Shop at http://www.rodshop.com.au.

The easiest way to identify your gearbox is to look at the location of the slave cylinder. If it's on the passenger side it's a W58, if it's on the drivers side it's an R154.

To convert the auto to a manual 7M you will need a flywheel, clutch pressure plate & thrust bearing, the bearing in end of crank. I have done a couple, its pretty easy. You will also need bellhousing for a manual box. Source a box that came off a 7M, either a W58 (n/a) or R154 (turbo supra).

Instead of a W58 box, you would be better with an R154 if you really want to do the V8 conversion.

The W58 should be good to around 500hp. I have one behind my 7M-GTE and its fine, but a V8 in front may shorten its life as suggested previously.

My preference would still be to do a 1JZ conversion, or what is known as a 1.5JZ conversion, which is a 2JZ bottom end with a 1JZhead etc, making it a 3.0 litre, but the 2JZ bottom ends are hard to come by. Just to complicate things and give you something else to think about.

hope this is of some assistance.

Michael

FWIW, assembled 2JZ-GTE bottom ends can be bought brand new from Toyota for approx $2500. That's not a bad price when you think about what you're getting!

I want something different I think. And while I'm doing an engine change I don't want to stop at just a 2.5L or a 3L when I can put in a 4L that will be strong enough for some stupid power. (Don't start a flame war in my thread please, I know the other engines are great)

My car currently has a twin plate, ceramic, brass button clutch in it, so I'm thinking whoever did the conversion didn't skimp. They may have even strengthened the inside of the box (don't know). If I get the car back tonight, I'll get under and have a look at where the slave cyl is.

Norbie

The 1JZGTE R154 5 speed that I fitted for VL1JZ had the slave cylinder on the passenger side. I just checked the photos to make sure of that.

Same here, factory R154s on Soarers - slave is on passenger side.

Hmmm, 1JZ's must be different then... I'm pretty sure with 7M's it's the other way around.

OK, So I don't know what gearbox I need Dellows to make an adapter plate for.

Anyone got their number? They're in the next suburb, but I'm without a car to do a driveby.

Anyone know what price the 1UZFE to Supra gearbox (don't know which one) would cost?

This is only true if you have a pre-89 Supra. 89+ models have an updated crossmember which is identical to the JZA70.




Is this true?
Coz my GA70 is a 89+, so would the crossmemeber be 'identical'?? How could I find out? I'm kinda in a rush, I have less than 2 weeks to know what I have to get. Also, is the sump the same??

May I suggest you take some measurements and pics of your crossmember, then go and have a look at a Pre-89 MA70 for instance. Most likely there were only ever two types of crossmembers. So if an Pre-89 is the same as yours, then you need a different cross-member.

You are welcome to compare against my 1986 MA70 if you wish. Unfortunately I don't have any pics. I'm in the inner west of Sydney.

If you need it complete in 2 weeks and you have a "M" series cross member, you may need to consider a 7M-GTE.

The sump is different between a 1J and a 7M if that is what you were asking. Hence the reason the cross-members are different. If your GA is 89+ sounds like you cross-member may suite a 1J. If yours and mine are different then most likely you'll be Ok for a 1J or 2J conversion.

I'll PM you contact details.

The overall shape of the sump and crossmember is the same for both the 7M and 1JZ, the difference lies in the engine mounts and the associated brackets on the crossmember. The 1JZ has alloy engine mounts sitting on round rubber donut things, and the 7M was updated to this as well in 89. Pre-89 7M's have the steel engine mounts which sit on angled brackets, the same as all earlier M series engines.

Norbie,
Are the sumps of the 7M & 1J much the same shape?
So to put a 1J into a Pre-89 the issue is really with the engine mounts then, not so much the cross member.
Do you think a 1J into a Pre-89 should fit OK, except for some custom engine mount brackets?

here's a slightly aside question.
the engine mounts I got made up for my 1jz (thanks dave) are angled steel, not "round rubber donut things"

what effect will this have?
