Something that came up in another thread, about fitting a gti dizzy onto a non gti big block, for better advance. Are there any simple upgrade dizzy available that fit the small block mk2s?
Polo MK2 GK engine code would be the one you want, 052905205R same engien the bigger inlet comes from https://www.ebay.co.uk/itm/202637396528
assuming its the later 3 bolt rocker cover type head yeah fits right on, forgot to mention as its the electronic ignition type. will need timing tweaked obv but I'm sure you can handle that
alternatively forget all that clockwork/vacuum gubbins, fit a fixed type dizzy and put a proper ignition ecu on there have it remapped for best results. ideally along side proper fuel injection, maybe throttle bodies, 1.4 ABD bottom end...
+1 for ecu ignition, through 29 minis, all modified plus countless other cars, best mod on the last one was megajolt ignition ecu, fully mappable and great info on them.
yeah so its got a better ignition curve in it, but tbh I'm not convinced its enough to justify the high price for a new one. if you get lucky with a used one on ebay then great give it a go. it'll only fit the later type head with 3 bolts holding it on, the earlier 8 stud type had a different dizzy and they're points ignition
When I was looking at ignition systems for the A series mini engine there was a distributor called something like 123, it was supposed to be brilliant and selectable settings, I'll see if have a link to it if fit other vehicles. Edit https://123ignition.com/ Couldn't see an option for golf etc. Megajolt was 4 wires and a coax for the sensor, very easy, I had to put a diode in so didn't get feedback voltage from ignition charge light when turned engine off which was enough to keep it running, but no big deal to do.
I've already ported the head, re profiled the valves, there's a fast road cam there for it, a 4 branch mani, and a mk2 gti system, I've already built a bike carb induction system on it, which it's been running a couple of years. Hopefully once C19 restrictions ease, we will get to put it all together. By fixed type dizzy and proper ignition, I presume you mean NoDiz or Omex, DTA, John? We would love to, but we're trying to keep costs down. That Polo GK idea sounds interesting, as it does indeed have the 3 bolt rocker cover.
yeah so if its later type engine with 3 bolts holding the rocker cover on then the dizzy I mention will all work, the GK code one is highest performance std engine I know of with standard carb & dizzy setup its the MK2 Polo GT 75bhp engine or yeah some kind of aftermarket mappable ignition, use a later fuel injection dizzy which has no advance mech inside and let the ignition ECU deal with it. will give you more flexibility vs messing with old clockwork stuff, you can find guys out there who know how to adjust the internals of these things but not many of them left
basicaly how the 16v left the factory, fuel all mechanical and theres an ignition ecu which takes care of the advance. in theory you can use a kr ecu with a fixed type small block dizzy but obv the ignition map isnt going to be ideal
Yes, put it in the mini I built couple years ago, 998cc and supercharged. Absolutely brilliant, easy starting, totally variable not like the dizzy on my old supercharged minor which never ran quite right. Even when removed supercharger and ran a normal carb set up it took about 3 minutes to change the 'map' and run it as an aldon yellow distributor, but far smoother. No damp issues either. Fitted a trigger wheel and sensor, then it was coax from that to the ecu, 3 core to the coil, and had ecu, fuse and edis unit mounted on a board under the dashboard. +ve, -ve, ignition, one or two wires to edis and tacho signal (from memory). Used the map system so ran 3km tube from manifold to ecu. Only teething problem was the charge light on dash would give enough feedback voltage when turn it off after running to power it and keep going, a diode sorted it though. Edis and coil were from a late escort or fiesta, it's more complicated reading about it than actually fitting it all together. Need (or access) a decent strobe to set up, but if slightly out can adjust via laptop. https://youtube.com/shorts/19d8DC8cS1M?feature=share
That looks class. You mentioned a coil AND an Edis unit? I thought EDIS was the 4 pole wasted spark coil pack?
