Don't lock the timing for a NA engine! :yes:

 

Getting rid of vacuum advance is as easy as removing the vacuum line from the dizzy.

Locking the dizzy stops it from advancing with mechanical advancement, and it will run like an absolute dog!!

 

Changing the throttle body is all good, but really, whats the point if it then has to flow through a hole the size of a 50c piece once its bee throught the throttle body!! It's still a restriction!

 

What are you like with a welder? Could always make a new plenum and runners to were it bolts onto the bit that holds the injectors! Then you could get the most out of the bigger throttle body. :P

I'm running fuel and ignition ecu so the dizzy mods will be needed and locking is one of them.

 

4ke throttle body has a TPS switch not a percentometer like the VN does which works better.

 

I can't alloy weld but a mate can.

Ah ok, get you now, so you need to lock the dizzy to give an un-changing TDC reference for the ECU?

 

What I meant with the throttle body is: the 4ke has a throttle body the size of a 50c piece, and hence the opening to the plenum behind it wouldn't be much bigger. The VN one would be more like a tennis ball. So once air has passed throught the tennis ball sized TB, it then has the same restriction of the 50c piece plenum opening.

Yeah i got ya.

 

Correct with the dizzy remark.

Road worthy tomorrow arvo hopefully.

Hehehehehehe......mine runs around 28degrees all day every day. Locked for the pure fact that the mechanical advance was working too well and advancing beyond 40degrees.....couldnt be rooted playing around with different springs so we welded it up! And 28 degrees is where it makes the most power.....so we tuned it to that. Been running a treat ever since.

I personally don't like welding dizzies to lock them, its too easy to warp the shaft with the heat.

 

Quickest and easiest way to lock a 4k dizzy is replace the springs with cable ties!! :P

Or if its a 3k dizzy, just put 2 small cable ties in the slots the weights slide in. :P

That single window is god's gift to blindspots!! My KE36 van is nightmarish for blindspots!!

Oh god yes, If it was metal I'm sure i would have hit the garden shed.

 

Well it failed the roady.

 

Needs bog touched up and rear shockies replaced along with LH tie rod.

Thats bugger all... I've registered worse :D

I thought road worthies were the easiest thing to get in beaudesert :D

They are if the road worthy bloke hasn't been done for dodgey ones. he is loosing his licence in a month so i better hurry.

Ha, So when do you plan on doin the efi conversion?

When money permits and after rego

Tie rod replaced, Rear dampers replaced, Bogged some rust.

 

Will try for a road worthy again later on.
