Re: Mk1 Hybrid Project
Just thought about it, and decided your right and I'm wrong! If the dizzys are the same part number then the keyways on willy and valver cams must be in the same place.
Good luck with it mate, let us know what you find :)
Re: Mk1 Hybrid Project
think about it mate. The cams could be 180 deg different. It's the keyways on the cams that locates the dizzy. If the either of the keyways were moved 180 dgrees in relation to the cam lobes then the ignition timing would be 180degrees out.
I find it unlikely but it's a...
Re: Mk1 Hybrid Project
tappets won't cause you any many problems, but it needs a good hour before they fill properly. I fitted a valver engine that had been standing for quite a while and it took about 1 hours running before the tappets filled.
Just looked through my part numbers PDF, F7P and...
Re: Mk1 Hybrid Project
which dizzy cap and rotor are you using, do you know if they are any good?
Also did you use the haynes manual method of filling the tappets with oil before fitting the head? Although that causes noisy valve train and poor valve lift it won't cause it not to fire...
with your standard management it's a pretty safe setup as long as the fuel rig is correct. 16v tanks have a swirl pot as standard don't they (or at least they are safe for track work).
As long as you know what your oil is doing, i'd say you'll be ok.
Get a wideband and monitor AFR. The engine is a standard 172 lump so if your using the correct fuel pump and reg, fuel pressure will be fine.
actually, what management is it on? Standard mgmt iirc? in which case there is not a great deal you can do about AFR anyway, so i'd stick with what you have.
^^He shouldn't need to, the engine was easily good for the power and more with those components in. Just needs a new 'rod^^
crank regrind, custom journal shells, new rollers in the top, possible oil pump replacement
(the list could go on, but you don't know that yet).
imho mate, save yourself...
the crank may also require re-hardening as the hardening processes used don't penetrate, they are just on the surface.
I'd just go for a new crank, as difficult as it may be to source.
That or give it to a really good engineering company WITH your rods and shells and have them check THE LOT.
find out the stroke of both. See if the F4R will give you more stroke. If it does then this certinally sounds like a good thing to try. No idea if it'll fit or not.
by gearbox seals, do they mean inner CV boots? I suspect they would....
And get a second opinion on a the cracked shaft. You'd be the first person to have had that i'd think
don't see any reason why things should go wrong or your car burn to the ground.
Do it properly. Consider the use of fuses, and wire into the door switches.
