Outer Limits 4x4 Board

I fitted a Crane Cams Fireball XR3000 kit and PS91 coil and 9mm plug leads last Thursday, because I was having probable water induced problems with the Pirana setup, I took it offroad to Cruiser Park and am happy to report that it now spins miss free at 6500rpm :-)

It cost about $550 all up including a $30 plastic box to keep it dry and I seem to be getting nearly 380km per tank now mixed usage. It took me a day including rebuilding the dizzy with a new bearing. I'll try and post some pic's later. Crane part #'s are 730-0091 and 3000-0231.

I will try the modified rotor trick this week too.

what's involved with this kit compared to just a replacement of points like mine??? as water still affect's mine do to the dizzy cap & rotor button still playing a roll

If you have good leads & cap, water doesn't worry the ignition with points, try hosing it while running to find the sensitive spot.

Anyway I am running a high energy coil which should be able to blast through moisture better, haven't hit it with the hose yet, but my Landrover became waterproof by fitting a Commodore Holden 6cyl HEI system to the 186.

Fitting involves removing the option for an easy change back to points, so fitting it to a spare dizzy is the safe way to go. You could easily install it without removing the dizzy from the engine which is the way the kit details it. I found an $8 bearing in the bottom that was stuffed and replaced it. The baseplate is easily removed and also actually a bearing with a bearing race around the bottom edge, but doesn't do much work, so I just cleaned it with petrol & regreased, I also blunted 2 drill bits trying to drill mounting holes in it, I ended up drilling out the points mounting plate rivets, removing that plate from the bearing and using one of those holes.

You then use the brackets supplied and a 1/8" bolt to fix the sensor to the plate so it lines up with a universal 6 slotted disc that mounts on the dizzy shaft lobes, I stuffed the clip inside mine pulling it off so ended up using silastic to keep it on the shaft, I would probably recommend locktite or plastibond just to be sure as it's not a great fit. You have to line up the sensor with the rotor and one of the dizzy leads on the cap, the kit says No1 but I used No6 because the vacumn advance rod was in the way.

The ignition unit is basically plug in to the dizzy, it only has 3 other wires, one to the 12v ignition supply & positve side of the coil, one to ground/chassis, and one to the - side of the coil and tacho.
The ballast resistor is removed. It has a diagnostic LED on the side of the ignition unit that you can see light up as you turn the dizzy around by hand.

I set the timing by the "drive down the road see if it pings and play with it" method, might get a timing light on it this weekend.

I installed the ignition unit and coil inside a plastic box screwed to the guard next to the coolant overflow bottle, pat pending Team Sh*tter Waterproof Ignition by Tupperware

doesn't really sound any different to mine, mine only cost $365 installed, then i added a high energy coil.
i've shown you mine now can you show me yours

I ran a Piranha system on a 4.2 for 6 yeaqrs with no probs, ran under water too until HV broke down.

That picture looks like the inside of my other dizzy :-)

I'm not knocking the Pihrana system, it was still working, and is still mounted with it's coil in the engine bay, dizzy is in the boot. It just had a funny miss every now and then. The miss started happening after the main unit suffered a lot of splashing muddy water in a gymkana with no tupperware box fitted. I was also not real happy with it over 5000rpm

Value for money Pihrana is great, I just wanted more

Fark! I didn't know the TBs revved that high! I was amazed to see the pics on your web site . . . almost drowning your norkle-less petrol motor in the Pig Pen. Whoever said petrol motors didn't work under water obviously hasn't seen those pics!!!

That was with points still.
Nah it wasn't that deep, I've also got a splash plate under the front of the motor to keep the muck out, probably stuffed if it stays under water but I can pressure clean the motor without missing a beat.
