2JZGE idea... could it work?

[hottscennessey]

Hey guys,
I have been kicking around this idea in my head all morning, and I need someone to shoot it down before I get any sudden impulses.

WHAT IF:
I got a 2jzge, comepletely stock, installed it like I would a 1jz..

But instead of messing with a standalone, or N/A electronics, I ran it off of the 7M electronics.

hear me out, I'm not a complete idiot.. but I was thinking - little modification for a temporary solution.

I run MAF-T.. use that for airflow.
use side feed - low imp injectors and swap clips
Modify the alternator harness
use 7m water temp sensors
modify TPS harness
ISC should be plug-n-play
Knock sensors from 7m (tap the block for second sensor)
Ditch the CSI

Here is the part I've heard rumors about:

7MGTE CPS will plug into, and work on a 2JZGE head.

...so if that is true.. I use the CPS, and Coil pack/ignitor (obviously).

(researched and yes it does work http://www.supraforums.com/forum/showthread.php?t=347719&page=3)


from there I would have a block capable of what the 7M is and supposedly more (with a thicker HG). I could leave it N/A for awhile.. or add on a turbo. I am planning on going Megasquirt so don't flame me. I've just never heard anyone else mention this and was wondering if it was even possible.

I figure it's a 3.0 liter.. and with the not-so-agressive timing of the 7M it should control the 2jzge fine.

Flame away :nono:

that will work, people have done it before. if SF's search wasn't down you could find it.

The 2JZGE already has 2 knock sensors, so no need for tapping, and I believe the GE already uses top feed injectors.

 

[hottscennessey]

Awesome

So even the 7M injectors will work too?

 

[Ken]

Yes, they will work, as long as you are using the 7M harness. I am not sure if the 2JZGE injectors are high or low impedence. That's easy to work around though either way. Remember to use all 7M sensors.

 

[hottscennessey]

of course.. I'm thinking I'm gonna do it.

 

[RacerXJ220]

Uh....

The 7M CPS does fit into the head, but you have to cut a large part off of it, unless you want to guess where the CPS lines up off center of the mounting bolt.

Higher compression in the 2JZ-GE stock.

Redo the coil packs, swap the ignitor, too much work, etc... Flywheel and bellhousing are needed too. Motormounts. What else.... Power steering lines, a/c.. there's a lot more to it. Good luck.

Just use a 2JZ-GE harness and ECU, around $300 pays for everything on the 2J-GE engine, including the wiring harness and ECU. So much easier, especiallhy with the higher compression, you'll run it a lot better.

If you go with a Megasquirt, then you're good to go, but on stock 7M electronics? No. No way worth it for the money. I would like to see you try though.

Please do it, and be the first here on SM!!!

 

[hottscennessey]

Yea man, I'm pretty sure I want to do it now..

I was planning on using a thicker headgasket.. I'll have to read up on the N/A-T forums to see which size will give me the compression ratio I'm looking for.

Which part of the CPS would I have to cut off for it to work properly?

Thanks for the post man, I appreciate your input!

 

[RacerXJ220]

I'll go outside and get a pic, brb lawlz.

 

[RacerXJ220]

That's about 3/4's the way in. It doesn't really bolt on, at all, but it will still work with cutting, trimming, sanding, grinding, then line it up right, and adjust it, etc.....


12 point crank sensor FTW.

Just plug it up and keep going!

 

[hottscennessey]

Ahhh, I see. Thanks for the picture man!

 

[RacerXJ220]

As far as headgaskets go, I got a 2.5mm, which brings the compression to something like, 8.7:1. 3mm is supposed to be 8.5:1, and 2mm is supposed to be 9:1.

I ordered mine from HPF, it's a cometic, and got here in less than one week. Don't pay $300 for one, call Eric@hpf.

 

[hottscennessey]

Great! Thanks! Looks like you have pleanty experience with the GE-T's. are you satisfied with their performance?

 

[RacerXJ220]

I will be hopefully by the end of this week. In my signature, is a link to the engine built with pieces left over from the 1.5JZ-GE-TT. We're actually putting the 1.5JZ together after that one.

I just ordered everything I needed already for it, and did all the research for it already.

So basically, if you want to go 2JZ-GE-T, it's very very very simple.

Engine $300 (2JZ-GE local, expect $500-700 shipped) Stay away from VVT-i.

Headgasket $219

ARP headbolts/studs (I prefer studs) $120ish

550cc's $300ish

walbro $100

motormounts $190 shipped

Standalone $450-950-++++ (Megasquirt/Stinger 4XXX prices)

Intercooler and piping $300 (free if you use stock 7M-GTE stuff, you'll still need to make your own pipes)

Turbo manifold/downpipe/wastegate dump pipe $230 shipped(Ebay)

Turbo $whatever you want ($400 used 60-1)

Wastegate $50 (50mm China HKS knock off works fine).

Don't tap the block to feed your turbo, just use a Ebay oil filter sandwitch adapter $50shipped

Oil lines $ depends on what you want to use (long enough to go behind the engine to the turbo)

Drill the pan (it's free and mid-sump already)

Fuel pressure regulator (you have to get rid of the stocker. Use a M12 tap, tap the rail, and get an adapter, after that run any AFPR you want).

You might need to extend the throttle cable (I am putting the GE head in a 83 supra, it's different)

Wideband $250 (AEM)

And everything else you change over the same as a 1JZ swap, and there's tons of information on that one

Depending on your power levels, 550cc's and a 60-1 may not be enough. 700RWHP seems to be the highest reliable on the GE-T's. If you want to go for the better stuff it's up to you, I didn't go THAT cheap, but these will work fine. Good luck.

manuel will need a 1jz bellhousing aut should work fine, if its the 2jz auto. sounds good keep us up to date!

 

[hottscennessey]

yup 1jz bellhousing and 2jz flywheel correct? (1jz will work too right?). BIC motormounts for my pre-89 subframe.

that means all I need is an engine, exhaust manifold, custom exhaust, 1jz bellhousing, flywheel, alternator, timing belt, misc belts.

I havn't decided if I want to keep power steering or not yet. I'll have to weigh that out.

It's also nice that I shouldnt have to mod my IC setup too much either!

 

[supra87t/t4]

I posted this idea on SF awhile ago, I'll find a link. I originally got the idea from daveh. I bought a 2JZGE engine and just got my BIC mounts, but haven't gotten much farther on it yet, it's a winter project and I need to clear some space out first. If your serious let's pool out resources/efforts or at least compare notes.

not much real info, but worth a look

 

[hottscennessey]

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 .

 

[RacerXJ220]

I just don't understand why you would want to keep the 7M electronics. Piggybacks just don't cut it for me anymore.

 

[Evilempire1.3JZ-GTE]

yea screw the 7m crap just use the 2jz stuff
if you dont want to dive into it or spend the 400 for a bell housing and all the headache why not go 1jz ? its pretty easy and bolt in for the most part then if you want later use the 2jz block on it ?
you can use most of the 2jz parts on the 1jz and you can always go single and mod your 1jz later too.
