Multigroove bottom pully with trigger wheel.

[burnard]

Hey guys,

As some of you may know i have an E16se engine in my mini :)

I currently have a multigroove bottom pully which does not have a trigger wheel built in.
I want to be able to fit a distributorless, mapable ignition system, possibly even aftermarket injection, to the engine, so will need to have a trigger wheel for it to read.

Can anyone advise me as to where i can get a multigroove bottom pulley with said trigger wheel built in that would be suitable for for my engine and this aplication?

Many thanks,

Chris.

This probably isn't the answer you want, but im sure you can buy the trigger wheel separate and spot weld it onto your bottom pully, you just need to then get a sender with wiring and a bracket then to mount it.

That's how I've seen it for the Megajolt setups yeah, just need to make sure it goes on straight

X/C/16/14/XE has a multigroove pulley with 60-2 triggerwheel.

some 8v corsas had a single groove pulley with 60-2 trigger wheel.

either bolt straight on.

see someones project thread here:

the problem you might have is the difference in oil pump castings. i cant remember if the E16SE has a hole to locate the OE crank sensor used on the engines listed above. you can bolt it on anyway by setting the gap manualy (rather than using the dowel) but it will only be held in place using the bolt alone....but it works with no issues. It wouldnt take much to make a new bracket, but it would be so much easier using the GM sensor.

Hey guys,

I am aware that there are the weld on type trigger wheels, but my thinking is, if there is an OE one, then why bother with the hassle?

I shall have a look for one from any of the engines listed, unless anyone has any other idea's?

Thanks for the quick replies.

you can also use a single v pully and change out the alternator as well. its a straight swap. its lighter and thinner so may avoid clearance issues that you may face with a mini.

best to have a wander round your local scrappy. try and find one with less rust than the one shown in the picture.

[meritlover]

there's loads on eBay. One even has the part number you need. It doesnt get more straight forward.

Merit lover, You sir, are a legend.

I always forget about ebay as i never use it lol.

The V belt isnt as simple as a straight swap on mine, I have an alternator off a lemans car, (dont ask) on a custom mount so that it can clear the bulkhead.
But i still have very little room for adjustment, and i cannot source a single V belt the right length locally.

[meritlover]

No problem. if you get a crank sensor you might see what i mean about the oil pump. If you go aftermarket ecu, with the OE sensor the base timing reference point from memory is 120deg but check with a strobe first.

[bazil]

Just check the management you choose uses the same tooth count as a standard pulley as some dont,

[burnard]

I thought that most aftermarket systems were programable so that you could set the tooth count to suit most aplications?

Im not too worried about mounting the sensor, have made my own mounts for speed sensors and things before and all have worked well enough. :)

[meritlover]

most are but some are not. It's a valid point from Brazil.

You sound like you know what you're doing so no point telling you things you already know.

DIS with batch coils will be fine but you will have problems running COP using only a crank sensor though ;)

[burnard]

Building classic cars i know what im doing, but i have never played around with any sort of ECU management systems of any description.
Tbh, i understand very little about engines at the moment, but am making an effort to learn!

Also have no idea what DIS or COP stand for lol.

I know the management would need to have the crank sensor, throttle position or MAP sensors and engine temp sensors as a minimum, but thats about it.

I still cant decide whether or not i want to build a superchaged 1600 8v at the minute.
But we have to start somewhere right?

[burnard]

I get what you said now, read into it.

Im still unsure as to why a COP system wouldn't work?
Come to think of it, im not even sure why i would want a COP system on this engine. I am right in thinking thats the type where there are no HT leads and the coil is just plugged right onto the sparkplug?

I would be going with a coil much like what SBD supply, which is just like a block with 4 HT lead plugs on it.

[meritlover]

keep reading and you'll work it out. How else is the ECU going to work out when no1 is at TDC on firing stroke?

SBD coil is paired an runs wasted spark.

COP is good for boosted engines or those which run high RPM and/or high overlap cams.
COP doesnt necessarily mean it has to sit on top of the plug as you suggest. they can be bulkhead mounted and HT leaded up to the plug.

meritlover = jack of all trades & resident sex machine

[burnard]

I was under the impression that the gap on the trigger wheel indicates where TDC for no.1 is, and also the RPM.

I am rather confused and im not sure why now. lol

[meritlover]

It absolutely does. Problem is, there are 2 occasions in the cycle when each out of 4 pistons is at TDC and the crank pulley cant tell what one is the firing stroke. thats why you get away with batched DIS pack running wasted spark.

[burnard]

Right, i see what you are saying now.
So how would you would you go about getting the correct signal for the COP system?

Im probably not going to use that, but im interested to know.

[meritlover]

Cam sync signal from a second pick-up.

Every 2nd time the crank goes round it syncs with the cam so it knows where the stroke is on the 1st cylinder.

[burnard]

Fair enough, But not required on a wasted spark ignition system?

[meritlover]

Fair enough, But not required on a wasted spark ignition system?

what's not required? cam sync? not for wasted spark, no, that's why you're as well running a distributor. that gives you non-wasted spark, and very unlikely you'll get issues unless you are running rediculous adv, but that can be rectified by adjusting the rotor button to avoid cross-fire.
usually if you use a modern coil and ignitor (which has stronger spark) with a distributor you will be fine.
