2JZGE idea... could it work?

[hottscennessey]

Yea man, I know exactly what you're saying, and I know it makes little to no sense.. but I want to do the 2JZGE(T) because:

1) It's totally different
2) going 1JZ only to go to a 2JZ block is too expensive
3) I'd rather go straight to single than do mods on the twins

I want to do the 7M electonics becasue:

1) to say i've done it
2) I don't have to change hardly anything
3) It wont matter, becasue I'm definately going Megasquirt

All that really matters to me is the final product, guys.. a 2JZ NA-T on standalone engine management. I feel that it will be perfect without breaking my piggy bank.

Thanks for the input, I know I'm crazy, but to be honest, if the 7M electonics takes more than an ounce of energy, or if I have to say "its a PITA" even once- then I'll stop where I'm at and have my friend build my MS setup.

This is the only statement you've made that makes me think you may not be completely insane... :icon_razz

Do keep us posted on your wacky (albeit cool) project. :icon_bigg

 

[hottscennessey]

LOL thanks man.

Thats exactly why I'm not dealing with a 1JZ and its wiring, nor even run the 2JZGE harness/ecu. Too much work/money for something that will shortly be replaced.

 

[supra87t/t4]

Its funny you said "I'm 95% sure I'm gonna do it" because thats exactly what I've been telling everyone.

I'm going to do it.. I just cant decide if I want to run it N/A for awhile.. or if I want to dive in and do N/A-T. Either way it shouldn't be too difficult. I guess I should at least Tap the upper oil pan for the drain while the engine is out. I guess I should find an engine first before I even say that tho. lol.

In theory, it will work no problem.

try this one.. pretty informative.

..and I thought I was being original .

That must have been the thread I was looking for and could never find, I knew I had read it somewhere.

The beauty of this plan is that if the wiring/sensors work out ok, you can have a practically bulletproof longblock for not much more than it would cost you do put a MHG in your 7M, at least that's the way I'm looking at it. I could be wrong, time will tell.

 

[slidingsidewayz]

wow. so it is possible to do this swap... my buddy has an extra 2jz-ge motor just laying around and i've always wondered if i could swap it to my other 87 na auto and i just bought....
is it harder than a 1j swap?

 

[RacerXJ220]

I want everyone to put a 2JZ-GE in their MKIII's immediately! It's about the same effort to put a 2JZ-GE in, as it is to go single on a 1JZ with cams/springs. If you can, reuse a lot of performance items for the 7M like the intercooler, injectors, and turbo if you went T4 already, throttle body goes across the engine like the 7M, just massage the pipes.

I would recommend going standalone, a lot less hassle if you want to boost it. Most of the engines you can get come with the wiring harness and ECU. Just reuse the harness for an OEM look.

It can cost less than a 1JZ swap after it's all said and done.

 

[hottscennessey]

my WTB on clublexus.com gave me a lot of offers on 2JZGE's.. I'm hoping to find one for the right price before the new year.

Like RacerXJ said, I'd go standalone considering the considerably high timing in the GE's ECU.

 

[hottscennessey]

I'm looking at a particular 2JZGE out of a GS300- I was wondering if anyone knew if it was front or rear sump? I need rear- correct?

 

[RacerXJ220]

Yep, rear sump is what you need.

 

[foreverpsycotic]

IIRC, you will want a 2j out of a supra or a sc300

 

[hottscennessey]

just because of the oil pan, or becasue of other differences?

 

[foreverpsycotic]

yes, oil pan

2jzget for me!

My engine gasket set should be here on Thursday - then I can put the rest of this beast together and take some pics of it on the engine stand.

I would recommend taking the shortblock apart and cleaning out the piston ring lands though. I cleaned a shitload of crap out of mine. All of the hardware is reusable.

My engine looks GREAT. All cross hatch was still completely visible and there was minimal bearing wear. All components of the block have been painted with por15 engine enamel.

One of the things I like about the 2j is that it has rod BOLTS not rod studs and nuts like the 7m. No need to resize the rods if you change the hardware. Either way, ALL of my hardware to include head, rod and main crank bolts measured in spec and were re-usable IAW the TSRM for the 2jz.

VS.

http://cgi.ebay.com/ebaymotors/OIL-...011QQitemZ320063502780QQrdZ1QQsspagenameZWDVW Basic, with three ports for sensors and feed(s).

OR

http://cgi.ebay.com/ebaymotors/OIL-...011QQitemZ320062362454QQrdZ1QQsspagenameZWDVW AN-10 lines, oil cooler ready.

OR

An IS300 union bolt.

When you have the engine apart, that's when to decide whether to drill and tap the block or not. With the options above, you can also run an oil cooler, as stock, the 2JZ-GE does not have one.

 

[p5150]

No thanks to the block tap.

Have you seen any oil thermostat sandwich plates? I want to run a cooler, but only with a thermostat.

 

[RacerXJ220]

Edit: I just woke up...

Just giving you guys some options........

I plan on using just my oil filter relocation kit from my 7M (bolt on). Some 7M people already are using a Rx-7 cooler with the built in thermostats. On regular relocation kits (like the one I'm using) the lines will act as coolers, good enough for me.

That's all that's needed on the engine IMO. I thought about using my 1JZ stock oil cooler. The holes are already on the 2JZ-GE block, then feed it back to the water return on the waterpump.

yeah man, but built in thermostats, I'm not too sure about.

 

[7Mboost]

If your not going geT don't waste you time.

 

[hottscennessey]

I'm just going to use an oil filter adapter plate w/ a long feed and drill the pan out. (If I don't get a GTE pan w/ it)

oil pan situation is handled- he has a GTE he's putting in his GS300, so he'll give me whichever pan he doesn't use. (just hope its a MKIV 2JZ, and not an aristo)

Highpsi1jz: why? whats wrong with the GE and going NA-T? Last time I checked they can handle pleanty of power, reliably. Parts are readily available for it, and its different.

 

[p5150]

Im definately going to run an oil cooler - easy to install and worth the effort. Especially since im NATing it......

Im turning the front fog light holes into ducts for air intake and probably an oil cooler duct of sorts.

 

[RacerXJ220]

The IS300 union bolt may be cheaper than a sandwitch plate. I'm not 100%, but it works the same. The sandwitch just gives you more sensor/feed options, but if you're going single, union bolt. A search on www.clubna-t.com may yield excellent results on that topic
