Couple questions.

Will it make any difference on my XR2 ?
More power?
Where do I find ignition coils for twin plug application?
Does standard electronics handle this??

They should have come with the coil mount plate, which from memory used the 3 cylinder coil bracket. Just double up the standard coils. It's not a bolt on increase you have to play alot with jetting timing etc to get any gain and it's only small but all those little things can add up.

High compression is the only way to get extra power and/or extra economy for free... excepting of course ya gotta pay for the heads n bits to do it.

Hi,
Just found a pic from the heads on a Mod VP Merc 2.4.
You can run the heads on a 2.4 with 100 octane fuel.
