jono Posted October 27, 2013 Share Posted October 27, 2013 I am considering using the dizzy from the first series EA82T with three plugger ECU and separate knock control module, in a mongrel EA82 I have. Anyone done this swap ? Would need to swap in the four pinned module dizzy and its loom to KCM found beside the glove box, and also add its knock sensor. I have a block from a Nov 86 production L Series Touring Wagon carbied, fitted up with EA82T mpfi (+ EA82T exhaust valves and oil feed for turbo) heads and camshafts , mpfi inlet manifold and throttle body. Injector holes tapped and plugged. Fuel is LPG dedicated. I am thinking I can get best advance from the engine if I adopt the knock system and be non turbo for longevity on its compression. No idea what its CR is supposed to be Quote Link to comment Share on other sites More sharing options...
ruparts Posted October 27, 2013 Share Posted October 27, 2013 hi, the 85 gl-10's had a mpfi non turbo engine option, might find parts for your project on an 85, i think they had the early knock sensor system even though non turbo. Quote Link to comment Share on other sites More sharing options...
Quidam Posted October 28, 2013 Share Posted October 28, 2013 (edited) This is what I have from an '86 GL10. Edited October 28, 2013 by Quidam Quote Link to comment Share on other sites More sharing options...
jono Posted October 28, 2013 Author Share Posted October 28, 2013 (edited) I have got the bits, even the pins to renew wiring in the plugs if need be, and that is the diagram , yep, I have a Denso knock module I think came from a New Zealand model, black plastic box casing , got a USA knock box via T'subaru and an Australian knock box of the Hitachi metal casing box. US and Oz numbers differ. I am curious as to the suggestion of knock control of non turbo ! Maybe for a pollution control state ? Quidam, are you running this system as a conversion from kno knock control ? That check terminal is a beauty - I have set it up to monitor knock sensoring in my EA82T GLTA L Series sedan (auto RX is best comparison) Running 12psi boost, it takes a hot day of 35C and some load before it triggers off the 1.7V reading towards 4.5V on the in dash (clock hole) permanent hook up Edited October 28, 2013 by jono Quote Link to comment Share on other sites More sharing options...
Quidam Posted October 28, 2013 Share Posted October 28, 2013 (edited) I'm not running it at present and haven't pulled the wiring harness. Mine is the Hitachi metal box from an '86 GL10. I'm electronics challanged but I don't see why it couldn't run as a stand alone on a NA EA82. Any feedback on that is welcome. It's not unusual for a NA engine to have knock control. I had a '82 Chevy Van with a higher than regular CR that came with it from the factory. Electronic Spark Control and completely stand alone with a carb. Depending on load and fuel it was very effective for keeping the motor out of spark knock. Doug Edited October 28, 2013 by Quidam Quote Link to comment Share on other sites More sharing options...
naru Posted October 28, 2013 Share Posted October 28, 2013 I would swap the distributor advance weights and springs for the MPI ones if possible. The turbo dizzy advances a lot slower. Quote Link to comment Share on other sites More sharing options...
jono Posted October 28, 2013 Author Share Posted October 28, 2013 (edited) You can't be that challenged surely ? You have opened the box and looked inside, got the diagram, well US diagram anyway. I don't think my 86 diagram has the altitude bit in the circuit even though it is for 84 models only. 22070 AA 011 think is the same number I have from US 22070 AA 002 I think is the Oz version I am not up on the GL10 features ....our EA82's in turbo version were either the RX - EA82T PT4WD DR 25splines, disc rear with sexy chequered interior or the GLTA EA82T with 3 speed JATCO PT 4WD, disc rear, Power steer, air, choc brown interior (luxury) , later GLTA's got the E4AT and of course the variety of Vortex engine packages Good idea on advance being different, the dizzy also employs boost retard in the vav advance can...

Quidam Posted October 29, 2013 Share Posted October 29, 2013 Well, I gave it some thought. What was bugging me about it, a wire I remember seeing in a Chiltons manual running from the knock box to the ECU. I don't have the FSM for '86. It's the R/G wire for the altitude signal. So, it is stand alone. I have three disty, two engine wiring harnesses, one knock box. What I lack is removing the harness from the car. That, and I don't have a good vac can amoung the three. And for that I think I'd just buy an adjustable vac can and adapt it to the Hitachi. Shouldn't be all that difficult, we'll see. For all I know, I could have a NA MPFI disty and I'll check the weights and springs to see if there is any difference in what I have. I got that stuff all in one parts car I bought. The motor I have for this may end up around 10:1 CR. Doug Quote Link to comment Share on other sites More sharing options...
jono Posted October 29, 2013 Author Share Posted October 29, 2013 Does not look to need the manual with that diagram. I actually ran my turbo with one of the connectors undone, think it was the knock sensor plug with some other wires and not at the sensor. Ran fine. I had three vacs and all had holes - not good for your underpants when running propane - the hole feed boosted propane inside distributor cap , met a spark, went pooft, ask more of it, backfired and blew my intake ducting along the road. We have a company in Brisbane QLD that rebuilds the vac cans at about a third the price of new exJapan cans Quote Link to comment Share on other sites More sharing options...
Quidam Posted October 29, 2013 Share Posted October 29, 2013 (edited) One disty I have in pieces now. I took the mechanical advance assembly apart, as it was really gunked up. Much smoother now. Six ball bearings in there. Dual stage springs in the dizzy advance as I've seen in others. It would be hard for me to modify the weights with a different profile. This ain't no SBC, huh. But I can use different springs to effect the rate of advance. Presently there's 15.5 degrees mechanical advance built into the dizzy. These have the "big" disty caps, that's good. Sealed ball bearing on the upper shaft. I'll get an adjustable vac can out and see what I can do.

Quidam Posted November 2, 2013 Share Posted November 2, 2013 (edited) OK, took the vac can from a '86 carb hitachi disty. Housing is busted and it's for parts. it's adjustable on the vac adv. side and it bolts right up to the turbo disty. Lengthened the "arm" to fit by brazing, needs to be longer to work out here. The turbo disty is physically larger and that's the reason for the longer arm. The turbo vac can has a lot of parts to it for advance and retard. Retard not needed on N/A. I have a one ear turbo disty and two newer two ear distys. I had tenativly identified the one ear as an '85... So far the weights and springs in them look identical. I put the carb and turbo flyweights stacked together, and they are the same profile. The carb disty has lighter springs in the advance, I'll put these in and it will be better suited for a N/A engine, probably. TPIWWP, i know Edited November 2, 2013 by Quidam Quote Link to comment Share on other sites More sharing options...
jono Posted November 2, 2013 Author Share Posted November 2, 2013 Hmmm....where is my action man t- shirt ?? Wow, you don't muck around. I have a turbo dizzy in pieces - am a bit like that, pul apart, never put them back together. This one was due to xmas closures and no dizzy grease locally available. I wil keep coming in here, please excuse me if I don't say much - won't have done much Quote Link to comment Share on other sites More sharing options...
Quidam Posted November 3, 2013 Share Posted November 3, 2013 Well, I've had these pieces for a while and am no stranger to a disty. I found the single ear disty was a bushing type shaft so it is parts, the others are ball bearing. I have two complete distys out of four. One turbo with knock box, the other NA with knock box. Here's the basic turbo '86 disty. \ And here's the wiring. Large plug to knock box, small plug to knock senser. And of course, the knock senser. On a side note, I realized the XT6 is equipped with a knock sensor. I read where the SVX has one on each side of the engine.

Gloyale Posted August 31, 2014 Share Posted August 31, 2014 And of course, the knock senser. That is a one wire Knock sensor used for later, optical pickup, ECU controlled MPFI. You need a 2 wire one. Quote Link to comment Share on other sites More sharing options...
