A small update..

Turns out (due to my ignorance) that the 16v dizzys have no mech. or vac. advance...

So.. This means that i have a few choices..

1. Go full programmable electronic (NOT going to happen!)
2. Get a mech advance dizzy off something else, pull out the mech. advance unit and make an adapter unit with the mech advance unit inside to go between the dizzy and the head.
3. Adapt an anticlockwise dizzy from another engine with mech. advance to my spec.

Seriously considering option number 2. Maybe option number three.

I went and talked to my auto elec mates Tony and Nick Agland that run an auto elec shop in town today about a Bosch High Energy ignition system using my dizzy and Tony pointed it out to me. Next week i'm going to go talk to him and discuss the options we have for this setup.

The high energy ignition system will utilise a Ford ignition module, because according to Tony and Nick, they have very good current and dwell control, and will probably utilise a Ford coil.

More info on this setup when i discuss it with Tony..

from aeons ago, i think its either a SAAB or Peugeot mech adv dizzy that fits straight in... have a search on vortex in the 16 V engine forum, think thats where i read it...

If you were an attractive woman, i'd kiss you.. Thanks for the tip!


EDIT: Mainly for my own reference, it's a Saab dizzy, so far i've found it says vac advance...

EDIT AGAIN: This is apparently the one.. Early 80's (82-85?) Saab 900 8v non-turbo.

[roccodingo]

Yeah, early 80's was about when i was looking for one as well...

Next trick is to find one....

Hehe, i have saab connections...

Er, well my old man does anyways. But if they are Vac advance that's not really what i want. I need progressive mechanical.

Dad's going to get on to the saab bloke on monday about it.

your intention is to run carbs yeah ???

Unsure if you can run the std dizzy and use the knockbox with this, but i would be sure there is someone on the tex thats done this before...maybe worth a search...

Yeah mate, DCOE's.

Knock box?? What like a detonation sensor?

It will be running Bosch high energy ignition. A custom setup. Its half done already cause we were making one for the 8v, just need a suitable distributor.

You'll have to help me out here.. As far as the electrical side of the 16v's go, i've got no idea. Never had anything to do with them before.

[Preen59]

No more guess work...



Just got it today.

[Preen59]

The crank is now at the reconditioners being ground, flushed and balanced. Along with the H beam rods, which are going to be balanced to within .1gm.

The crank journals are being ground specifically to size to give clearance of 2 thou (.05mm) on the mains and 2.5 (.0625mm) on the big ends.

The main tunnels only varied by 2 tenths, so they will be ground to one size, but the rod big ends varied by almost 1 thou. Specifically they varied by .02mm across all 4, so they will be matched to their respective journals.

These clearances are basically top tolerance (highest clearance) on the VW clearances given in the Bentley manual, which are pretty standard clearances.

So.. To all the people telling me to get into gear.. There you go, the ball is still rolling.

[Jarred]

rolling like a match of lawn bowls but...

Slow but precise. So yeah, you're right.

Righto mr "I'll just pay someone else to do it all for me".

[jayjay]

lol! i have no idea about porting and match porting! anything to do with proper machining. my tolerance is really low for how crap i am with a lathe.

i uh.. made a machining joke.

edit: LOL!!1
