Is this true?

I have heard a few places now that you can use the MKIII CPS in the place of the disi on the 2JZGE just wondering if this is true or not.

Man I dunno... Can you take a 7MGTE cam position sensor and use it on a 2JZGE in place of its distributor?

YES... now go do it and let me know how much you like it... :bigthumb:



















*sighs* no I dont think you can use a CPS in place of a distributor, unless you use a coilpack set up and even then, I doubt it...

NO, it cant be done. The 2JZGE Ing. system basicly the same as the 7MGE Ign. system. I computer does not feed the IGDA and IGDB signal that is needed for the ignitor to work correctly.

actually its true. na-t guys do it. you just cant do it w/ the stock ecu. i believe larry at sound-performance did it on one of his cars. i'll see if i can find the pics.

IJ-

i am not 100% on how they use them, i just know they are a direct fit and they work. i was pretty sure the guys running them were standalone ems but cant be certain. here are a few quotes from the na-t board.

any updates on this? What about using the MK3 CPS? Or is the gear different?

The MK3 CPS works great. I just got mine running with it.

I found that the crank position can be use from the MKIII turbo, however who makes the nifty ignition module? I was looking into msd, and other ignition manufacters.. So far, you car has to be DIS, to begain with.

there is another guy that lists his na-t kit for sale which lists the 7m cps as well, but i didnt see the need to post the whole list.

well here is the situation I am transplanting a 2JZGE into my 90 in Feb and acording to guys on supraforums its possible so if i do it i will be using all of my ign system i just want to know if mechanicly it will fit in there and work because i will be running an aem with it. so its like 50/50 so far,...... can anyone clear this up as being possible. Also I am willing to bet some money on it that I can run my 7MGTE ecu and harnes all i have to do is use or splice my sensors into it

hmmmm so maybe for a 2jz swap into a mkiii its not needed to get a full mkiv front clip and all corresponding electronics.

i wonder how well a 7mecu will run a 2jz motor?

if you're running an AEM universal, yeah probably it will work. it might be more work than just using the 2jz stuff, but it should be doable. you have to use the AEM stuff for some things, like the map sensor, if i recall correctly.

i dont believe the 2jzge has a map sensor i think it is only maf like the 7mgte i cant remember i didnt look at the eng pics too much. but here is what I think can be done and I will try this when i get back:
The swap is easy iam just lacking buying the mounts and the bell housing, I already have the 1jz clutch setup to mate the r154 to the 2J.
As i stated erlier im sure that the small things like the sensors wont be a problem i can always use aftermarket gauges.
As for the maf im sure i could use the lexus that i have or the jz pending.
then the throttle body im sure if the plug of the 7m harnes doesnt fit i can splice it in---im looking up wiring diagrams after i post this. hmmm i cant think of any other thing that may be a problem in theory. but i will research more before i get in the states then i will see how it goes. overall im willing to try it out

i bet you could run a 2jz with the 7m ignition system.

mkiii cps
mkiii coilpacks
retrofit a 7m tps
all other water temp fittings are a piece of cake,
use the KV AFM

wire it up with a 7m wire harness and ECU and BAM!

2jz mkiii swap on a budget.

ok the CVPS on the 7m is simple in its design.

Two signal for TDC #1 and TDC #2 (G1 and G2 respectively) then you have the NE1 signal which is the physical timing. This should work fine with the AEM or you can try the hall effect sensors. It all depedns on what you are doing :)

I misread your statement in the first post. Yes you can run the 7M-GTE CPS in the 2JZ-GE head but by eliminating the distibutor, you have to disperce the spark correctly and the only way to to that would be to run a complete 7M-GTE engine managment system (CPU, harness, related electronics) or to find someone that makes or make yourself a custom Ignitor unit. What exactly are you trying to do here? put a 2jz-GE engine in a MKIII and still keep the MKIII engine management? If so, then its pretty straight forward, just think of the 2J as a 7M and install it. Pretty much just a straight swap. if not then please elaborate more on what it is that you are doing or trying to do.

ok, I just went back and reread what was written again and now I understand what you are doing so forget my last post in asking what exactly you are doing. Yes the CPS will fit into the 2JZ-GE head. Like I said, forget about the term 2JZ and think of it as a 7M or for that matter a "new design 7M".... IIRC, most all of the 7M sensors will thread onto the 2JZ motor the rest will just have to be rewired correctly like the TPS. Outside of that, it should be almost exactly as you were just swaping in another 7M.

can someone pretty pretty pretty please post a pic of a 2jzge dizzy showing inside & the cap
i believe i have a 2jz dizzy running in my brothers 7mge cressida.. and working (rather well i mite add)

the inside of the dizzy on the 7mge looks similar to this photo (pic is of starlet one but inside design is mostly similar)
http://www.bajanchameleon.com/nodistribg1ge.jpg

if someone swaped the entire 2JZ-GE distributor into a 7M head then yeah it will work fine, but I dont think that the 2J cap and rotor will fit on the 7M distrubitor.

here are some pics
1st = 7M cap
2nd = 2JZ cap
3rd = 7M rotor
4th = 2JZ rotor
