Its going on a 1jz, but that should not make much difference. There no more than 1" longer than 2jz coils and I have seen those on 7M's with lots of room to spare.
ZZ coils would stick up to the tops of the cam covers, if not higher. I don't know if there is room to fit the throttle linkage with these.
I am putting the 1zz coild on my 1jz. I just finnished a LS1 coil setup on a 2jz swap, it turned out really nice. I will post some pics.
Alright, i have an update finally. The 1ZZ coils are installed and I have been running them for a few months now, and they work great!!. I now run a .030 plug gap and have boosted up to 25 psi and experienced zero spark blow out!!!, which wasnt possible with the stock coils unless running a .022 gap or smaller. I am totally pleased with the coils, the fitment and performance is great, I can finally turn the boost up without worrying about blow out. The center coil cover does need to be spaced up about 3/16", which is barely noticable and offers better airflow and cooling for the coils. I will attach some pics.
The coils are from the newer 1zz and 2zz engines, Corolas, MR2 Spyder and Celica GTS's. I will see how they fit on a 7M.

what ignitor are you using?? Are you going to be selling those brackets for the coils??
The Later model coils are even hotter again Randy, I'll have some data this week after a visit to MoTeC to have some tested.becauseican;1336733 said:

Like Turbo Drifter said, they have built in ignitors, which is why they are so great. I have heard it direct from some standalone ECU companies that the stock JZ ignitors are "junk", and they dont reccomend to use them. They only work well with a booster like MSD or HKS DLI.
Yes I may offer these brackets for sale, although there is more to it than just the brackets, I will see if I can get some brand new coild and offer it as a package. PM me if interested.

That is mainly because most standalone ECU's do not have enough coil drivers and must run them in wastespark, doubling the duty and reducing charge dwell and cycle by half.
All of the latest ECU's that do have 6+ coil drivers are doing well including AEM EMS v2, ProEFI, and Motec.
Randy I found a easy fix.
Forget about epoxy and all that crap I found shrink warp that fit perfectly, and i haven't had a problem since on all 18 of my cracked coils on my 3 2jz cars.
In fact the mk3 made 4 PSI more boost form better ignition when I fixed the coils.
Had to turn down the boost control to compensate!
The cracks that affect the coils I found where mostly the ones going down the down the coil to where the boot is... I took a whole piece of shrink warp down the shaft of the coil and haven't had ONE problem since.
BTW using A DLI helps crack the coils by over driving them.. I had 3 sets crack because of the DLI. but fixed as per above.

Zazzn, are you saying that it's safe to run a DLI so long as the coil pack stems have been wrapped with heat shrink? BTW, I run 2 layers of 1" heat shrink on my coil pack stems.
