That's the one I've linked to above, did you go for the VW one or the Porsche?

Looks remarkably like the wosp. Albeit slightly cheaper! Thanks I'll do some research.

Dave.
Cheers Dave, I did see that. Little info as to what is actually reqd. though. There's a better thread over on the Cal look lounge with a little more detail and also a Finnish site has some info. Seems you cannot mill/turn down the mounting flange enough to get the right engagement. There a are a few mods to do to make it work.

What kind of cylinder pressures do you have? I have 165psi on a stock cam 2.4L and it spins pretty fast with a stock starter. For that compression I assume you have a cam with a lot more overlap in your engine? I'll see if my rev counter shows the revs while it's cranking but the speed is almost irrelevant if it starts immediately.

No idea what pressure I have, a lot.
260 0.050"
300 adv

10.2:1

Issue I'm having is the ECU doesn't realise I'm trying to start the engine I don't think as I can't hold a good enough RPM whilst cranking for long enough!

I bought the VW one.
It will spin real slow with that comp. I'd take the plugs out ,spin it over till the oil light goes out, once it does this, you can move on knowing that when it does fire, oil WILL circulate. 1 IMPORTANT thing LESS to think about.

I've had it cranking to give oil pressure, did that with plugs out and rockers off.

The VW one is 1kW.
The Porsche one is 2kW

Any detriment to fitting the Porsche one?

adding jumper cables and a good battery will rule out battery,
adding a jumper cable from the engine to the negative of the battery will rule out earthing.

i recently went through this and tried all the above, in the end it was worn starter bush causing the starter to ground out internally.

i stripped and cleaned the starter and polished the contactors, new bush, new earth cable ect now it cranks well on the stock sized beetle yusa battery

i'll look through my logs and see what its cranking at

You wont need to change the starter bush with 1 of those AES starters as its a direct drive .
