I fixed the centrifugal advance, and it has fixed the high rev problem nicely (engine also runs much smoother). However, the surging with low throttle remains. I would like to check the throttle stop screw adjustment before looking at the TPS etc, does anyone have any more info on how to check this other than what naru mentioned above? Thanks.

I doubt it. THe stock fuel injectors will be oversized to some extent. Do the mods, and if the engine runs lean then you know you need bigger injectors.

Why not drop it out the bottom? Much easier.

Thats odd, my '81 clutch (small) used the one on the right, which is also the one i'm now using with the '83+ size (big) clutch.....

You won't gain anything from an injector swap unless teh stock ones cannot deliver enough fuel. THis only happens when your engine is recieving much more air than stock, liek when you increase the boost on turbos, or possibly if you did some significant porting work on an N/A. You can't use more fuel unless you can get the air to burn it.

I think going to the dealer will be your best bet, but it may be expensive.

A lean mixture can cause overheating exhaust. You might want to check this first.

THe line going from the rocker cover to the filter box - this was an new zealand ea81 - very simple no emmisions, so yours may be different. I havn't replaced the rings, the enigne is sitting in teh garage as the car is off hte road at the moment. I think a valve is at fault in my case (not seating properly), as the enigne had new rings only about 80,000 kms ago.

I had this prob, and "fixed" it by installing a filter such as is found on a pneumatic compressor. the filter was inside a can thing with an inlet and outlet hose fitting. I simply installed this into the line, and emptied the oil in the bottom into the engine every now and again... A little crude, but it worked..

You sure about the whole ea82 in an 83 bit??? We sure don't have ea82 styles in 83 in New Zealand, and we usually get the same models as Australia....

Or you could put a horizontally opposed porsche engine in!!

Check the camshaft lobes for excessive wear and/or damage. Make sure all bearing surfaces on the crank shaft are good, if not have them ground. Check that the conrods are straight within specs. And don't forget to have fun!!

What kind of signal does the injector recieve fron the computer? maybe a better idea would be to build a circuit that will 'split' the signal to two injectors, ie if it is a DC pulse signal, one injector could recieve every second pulse, the other receives the next???

Hey, I say go for it. It is something that i have often thought about. There would be some fabrication involved, but nothing too extreme. You would need to make a water cross over (I think) and set up a thermostat. The thermostat could be easily made using a gm one that comes with the housing. You'd just need to make a backing plate for it. Those intakes are just screaming to have a carb each!

Are you planning on modifying the ej? They are not that powerful stock, so the box would probably be ok untill you mod it...

I don't understand why you guys are having such problems??? As I mentioned, my 83 turbo wagon has an 81 DR gearbox, throwout bearing carrier and throwout bearing, with an 83-84 clutch disk, pressure plate & flywheel. Is this different to what you are trying to achieve???? Maybe there is some difference in the diameter of the hole through the pressure plate fingers from brand to brand???

Doesn't sound as if its foaming, as such. Small amounts of bubbles are normal, the oil going all foamy isn't - this generally happens when the wrong oil is used.

I'd say it will be the headgasket, often the only symptoms are bubbling coolant and overheating...

No, the engine starts just fine. I think you are thinking of the ignition switch. The ignition module is inside the distributer, and is used to signal the ignition coil to fire at the correct time (like ignition points on older cars). It is called a module (instead of "pickup coil") because it has the ability to change the ignition timing slightly when signaled from the knock control unit.

If they are the same as the turbo injectors, they can be replaced with nissan 300zx (i think its that one anyway) injectors, which are capable of a much higher flow rate. These would be the way to go if your going down the megasquirt road..... Nothing wrong with the original distributer, as far as i know.

I prefer dropping the entire engine/gearbox assembly out the bottom! Then you don't have to worry too much about engaging the input shaft into the clutch!

Thanks for the offer, but i think ill go new if the module has to be replaced. I can get one from subaru for NZ$250, and can probably get the AC delco one for around NZ$100. My reason for this is that if I get a 2nd hand one, there is a good chance ill have to replace it a few years down the track, and by then they will be even more expensive! Cheers Anyway!

Get a decent sized one - at least 400-500cca.

For anyone that might be interested, I found a part number listed for the ea81t/ea82t ignition module. Its an AC Delco part# E1914C. The website i found it on had it priced at almost $600, so its more expensive than the one from subaru (at least there, ill find out what i can get it for from repco).

Simplest thing would be to go with another good 'ol ea81...... nothing wrong with them if you ask me!
