Orin... mind if I throw this info onto my "Where to get 1J parts?" page?

http://www.autosoftsys.com/supra/misctech/1JParts.html

 

This is perfect 51 cards

This is exactly what I had in mind. Maybe it can become a sticky.



"Ok... I have a rare engine... where do I get parts in North America???



I have seen many people asking one of two questions:

A. Where can I get parts for my 1JZ?

B. What parts are interchangable between the 1JZ and the 7M or 2JZ?

I have posted the following list a couple of times on various forums but I figured I should finally post it someplace permanent. So here you go... this is what is interchangable between the 3 engines... the 7M, the 1JZ-GTE, and the 2JZ-GTE. Also below I have added where you can source a few of the other common parts for the 1JZ engine. Anyone who sees errors or has additions please contact me and I will keep this list up to date.


Common parts between the 7M and 1JZ
- Clutch kits (but not flywheel)
- Cat back Exhausts
- 89+ motor mounts (rubber part)
- Anything trans (R154) related
- Anything gauge related
- Rad (if you're not using the 1J hydro fan setup)
- Driveshaft/Diff


Common parts between the 2JZ and 1JZ
- Power steering pump
- Alternator
- Spark plugs (ngk 3330 and 6097)
- US spec 550cc injectors (resistor pack needed)
- JDM Spec 440cc injectors (drop in upgrade)
- Water Pump (requires removal of the 1J hydro fan and a 2J pulley)
- Head gasket (although most other gaskets do not swap, get a 1J set to do it right)
- Clutch fan (if you use a MKIV water pump and pulley)
- Serpentine belt (but NOT timing belt - see below)
- Oil filter and relocation kits
- Intercooler kits
- Plug coils
- Cam gears (incl aftermarket adjustable)
- JDM 2JZ Map sensor
- Ignitor


For a 1JZ timing belt:

The 1988+ Isuzu Trooper 4 cylinder 2.6 liter engine (4ZEL) uses the same belt as the Toyota 1JZ engine. So instead of getting a belt from Japan (~$100) you can pick up an Isuzu Trooper belt locally at an auto parts store for about $30 US. Make Sure You Get The 4 Cylinder 2.6 Litre Engine Belt!


Timing belt specs: 137 teeth, 25mm wide


For an aftermarket flywheel:

Order a 7M fly but have the 2J bolt pattern drilled into it.


Very general rule of thumb:

From the Clutch/Trans back it's a regular MKIII Supra (save for the Torsen diffs) From the FlyWheel/Bellhousing forward, it's 70% 1J / 30% 2J parts.


If it's not on the above lists... assume the part to be unique to the 1JZ. If you find a 1JZ part that is interchangable, or can be sourced elsewhere and is not on this list please contact me and I will add the information to this page.

Here is the site where you can get your "zener diodes" for cheap: http://www.futurlec.com/Diodes/1N4732pr.shtml

No more boost/fuel cut after putting this little thing on

 

What? Where does it go?

 

Can 2jz piston rings be swapped onto a 1jz piston, or would the 2jz piston need to be used as well? I thought I recalled a difference in the rings being mentioned......

 

Ditto on hearing something about the 2J/1J rings and ring seats being different sizes.

 

Filling required.

I used a set of 2JZ piston rings in my 2.5 block and only have to file the piston a little for the top ring . It worked ok. You can get the correct thickness for the rings by measuring the 1JZ ones and ordering them from Hasting or the like.

 

This is a great thread... I am about to purchase a half clip from Jarco, and I plan to rebuild the motor before it goes into the car. It's good to know that 2JZ pistons and rings will work in the car. It's also good to know about the bearings, because I was curious to know this...

Anyone know where to source a gasket set to do a rebuild?

Thanks.

Arnout with SupraSport in Europe can probably get some for you. I got my gasket kit from Jeff Watson at Champion Toyota, surprisingly.

1JZ doesn't run a No1 Main bearing (23mm width) in the first main cap - it runs soley No2 bearings (20mm width).

$100USD for a timing belt? Tell me you're joking. You can pick them up for $44AUD ($33?USD) from Toyota Oz.

 

Shipping stuff across the ocean is a PITA and lots of toyota dealerships in the USA like to gouge people on special orders like that.

 

Trannies...from what I've learned so far...and OB1 JZA70, you're my hero for the flywheel thing...I didn't know they could do that...just gotta build a budget for it...

MKIV W58 (?NA) is bolt on with 2jz W58 Flywheel
MKIV V160/161 is bolt on with appropriate flywheel
MKIV Auto...same story

MKIII W58 and R154 need the 1jz-GTE 5 speed bell housing to bolt on. W58 will require a custom flywheel for the NA MKIII with the 2jz-GTE bolt pattern drilled in. R154 will need the 1jz-GTE 5 speed flywheel or a custom 7m-GTE flywheel with the 2jz-GTE bolt pattern drilled in.

MKII manual trannies require the same. Tranny linked to a 1jz bell housing with either a 1jz-GTE 5 speed flywheel or a custom 5mGE flywheel with the 2jz bolt pattern drilled into it.

MKIII and MKII Autos will require the 1jz-GTE or 2jz-GTE auto bell housing, TC, and flywheel. I'm vague on this but this as it's hard to find info...not many people go with the auto.

Things I'm unclear on...

Are the 1jz and 2jz manual (W58) bell housings the same?

If a machine shop taps holes in the 1jz/2jz patern around the 7m-GE or GTE flywheel will it effect performance?


Also, for those custom flywheels with the 2jz pattern...this may be common knowledge...but Fidanza is happy to help you.

 

Fadonza and Mueller fabrication both can help you with the 2jz bolt pattern 7M flywheels. I spoke with Rob at RPS and he said he could do the 2JZ carbon Carbon clutchs with the R154 spline clutch which would give the big hp guys some added clutch surface. This would aid in slipping the clutch for instant boost. The added area provides the needed clamping area for 700+ applications that are in the making as I type. TRD stamped (Exceedy) twin and triple disk clutches come with the flywheel for the 1JZ GTE and are quite streetable. Blitz also can get there 1JZ twin disk to us over here in the US. W 58 trannies wouldn't be my choice with the addition torque of the JZ engines.

 

I have no idea how I manage to slaughter "Fodonza" so badly every time I write it...

W 58 trannies wouldn't be my choice with the addition torque of the JZ engines.

Just thought I'd throw it up there for other folks like me. I'm going to bolt up my W58 until I get my hands on an R154...which should take about a month...if the W58 lasts that long......

 

orin: do you need anything off the 1jz block to swap the 2jz block in an 89+ chassis?

 

what a great thread

 

orin: do you need anything off the 1jz block to swap the 2jz block in an 89+ chassis?

You'll require the upper aluminum part of the 1J engine mounts.

 

r the 2 oil pans the same meaning the bottom part ::black: not the top which is aluminumcuz i am in need of one for my 1jz-supra

thanks, where can i find these/how much should one expect to pay for used ones?

The 1JZ and 2JZ rear sump oil pans are the same.

That's going to be tough. I'd say find someone parting out their JZA70 clip, but even then they might not be willing to sell individual parts off the engines. Probably your best bet is either finding the part numbers for the engine mount brackets and calling Jay Marks Toyota, or just contacting Arnout in the Netherlands, since he's a good source of 1JZ-specific parts. His page is here:

Excellent resource, too.

Good luck,

Matt

 

thank u very ,much

 

Every sensor on the engine with the execption of the fan temp switch in the radiator, idle air control valve,and map sensor are your standard toyota pre obd2 sensors, not just 2jz but just about every other toyota engine made. Map is unique to the 1jz,but could probably get a aftermarket one to work. Who care about the fan temp switch, it doesn't really matter anyway because it is almost impossible to get the hydro fan setup to work as designed, it has multiple speeds. The problem is when you do not swap the ac compressor top half(you use the 7m one and the 7m ac controls)the fan ecu does not get a signal and it's designed to go to a higher speed once the ac is switched on, without the signal the fan just goes full blast by default. To get it to work would be much,much,much,much more trouble than it's worth. Crank and rear main seal can be bought at any toyota dealership as well as valve stem seals. Cam seals cannot be, but Suprastore europe has got them for me before. I had thought my idle air control was bad at one point and then destroyed it while attemping to dissassemble. I took a 7m one and modified the mounting flange and it worked fine, it's only a stepper motor. People must think toyota doesn't want to make any money when they talk about 1jz being hard to find parts for. TPS is the same as 2jzgte,valve cover gaskets are not exactly the same, the 2jz have an extra "hump" in them, but they can be used and not leak if needed, just have to straighten the bend in the rubber. I've yet to have a problem finding parts really, it's not like toyota makes all special parts for each engine. It may take a bit longer,but it's not going be like damn, my coolant temp sensor is no good, might as well throw it away. Not to mention things don't always have to be a direct bolt on piece to work, sometimes things need a little modifaction.

 

Also watch for cheap engine sets for sale, I picked up one on ebay almost complete(almost, that is why is was sold-BUY A CLIP IF SWAPPING INTO A MK3) I sold the intake manis,oil pan,harness,and other pieces and got a free long block and made some money. Too many people buy engine sets, you will spend more money buying the missing pieces to complete than a clip costs.

 

So it's a little better to get a 5 speed half cut right? Since I already have an R154, I only have to swap my R154 bellhousing to the one that comes with the clip, right? Again, if I get the 5speed half cut, I use the flywheel that comes with the clip and a clutch kit for the 7M, right?

 

Jeff @Jay Marks Toyota carries 1JZ cam seals(special order from Japan, $5 each). HTH.

 

jose. i looked up the seals they belong to corola and so on from 93-01
