ignition dramas on the rolling road
Turbo Mini Forums

took my car to motorscope in northalerton (north yorkshire) today to try and sort out my timing. the operator after a hour of tweaking claims it to be my ignition, as it would misfire at 3,700 Rpm onwards and im only producing 40 Bhp. my engine spec is

998 standard block and gears
12g295 head
R5 T2 turbo
HIF 44 turbo


he said i should replace my dizzy with a electronic one and renewing my leads and coil. ive been looking around and i saw the the electronic ignition pack from mini spares

was thinking of getting this with a new electronic coil and some new leads would this fix my problem. i know megajolt/megasquirt would be better but with the Christmas period coming up im after a quick fix

SHUT THE PLUG GAPS UP?

what do u mean by shutting the plug gaps up

What dizzy have you got. If it still has points it is not very suitable unless you have it locked up at a fixed degrees.

You'd be better using the Metro turbo dizzy if you can get one.

Where in Yorkshire are you?

cheers phil ill have to have a look tomorrow but i might just renew the whole electrics

Ooops, didnt mean to put that in caps,

Wintersurfer on here had a similar thing on the rollers recently, it died about 3500 rpm and only made 60 odd hp,

Shutting the plug gaps up a bit totally transformed it, and gave 150hp.

'kin hell! Is that why we only got 150 bananas out of the van

cheers joe but i need to renew like wil said i need to get a metro turbo dizzy anyone got one spare

TBH I think the vans plug gaps are mahoosive. Perhaps if we close them up a bit it may help with the little missfire we keep getting.

If something is worth doing, it's worth doing half of.

wil how do fix your dizzy at a fixes degree is it hard to do

There is a BIG difference between what plug gap a spark will jump - especially under boost when the internal cylinder pressures are higher - between a conventional/electronic dizzy that uses a single coil and a rotor arm to transmit the high voltage, and a coilpack driven by MJ/EDIS/MS etc where the coil(s) charge cycle is much higher and there are no losses through a rotor arm......

If you use a dizzy, use smaller plug gaps.

Schrödinger's cat - so which one am I ???

so can i use my standard dizzy if i close the plug gaps?

It is possible, but you need to be careful of what the max advance is as it can be waaaay to high for a boosted engine compared to a N.A. engine. Many N.A. engines advance to 34ish degrees whereas a boosted engine should only go to 26-28ish??? I'm sure someone will post actual max advance under say 8lbs or so....

Also, as others say, you also need more spark power or smaller gaps in the plugs...

im thinking of the megajolt route now gonna pop to the scrap yard tomorrow and get some parts then order my MJLj V4 and give that a go just a quick question on the trigger wheel do you need to remove your engine to mount this or can it be done whilst the engine is in the car

MJ is the way to go. You just need a couple of blobs of weld on the bob weights to lock the dizzy.

You can fit the trigger wheel gubbins with the engine in. But you'll need to get the rad out and undo the NS engine mount and jack the engine up a bit.
