Coil-On-Plug Question

[AdeV]

I've been googling, as one does, and it seems the VVTi engine has coil-on-plugs?

Will these physically fit into/onto earlier variants of the 1UZ-FE engine? The reason I ask - I am turning a Mk3 into a trackday car, which involves a Megasquirt ECU; if the '98 COPs will fit into a '96 (IIRC) engine, then my "where do I get 8 coils from" problem is resolved :)

Cheers,

Ade.

PS: The 4 litre engine sounds SUPERB with no exhausts on it!

Ive seen on the altezza for heat reasons the coil packs being used with ht leads, so you could in effect use them even if they dont physically fit down plug holes.

True; I had planned on using 8 standard coils (of the type fitted to the Mk2 & 3, not sure about the Mk1 but I assume it's the same), are COP units lighter? I'm guessing "yes"...

1 unit weighs 8oz.

What's that in French? (apologies, I have mostly switched over to metrical weights, purely due to a reduction in brain power due to age/alcohol/girls [delete as applicable])

Anyway, I've just bought a complete set for £65 + postage, even if they don't fit the earlier engine I can use them on my road car...

LOL, in foreign its 226 grams, As you progress with project would like to see it if possible. New thread ?????

Sounds similar to the std coil then, I can't believe that's much more than 1/4 kg... Still, fingers crossed I'll save the weight of the HT leads at any rate :)

Pics/prgress thread - no problem, will do... see the main forum in a few mins.
