UK vs jap spec head question

Post by elrikos » Thu May 21, 2009 6:22 pm

hi guys,
the latest in my engine saga is my new one arrived today. issue with it is;

both front head mounts are snapped off. I've spoken to the yard in question who are being very good about the whole thing. One option suggested by me is swapping the head off my blown engine (bottom end damage) onto this new engine. I have a sneaky suspicion that the engine is a UK spec one however as it has 2 chromed pipes which i think are for an oil cooler. Would this indicate that its a UK spec as my jap import NC doesn't have these.
I wanted to check that the heads are the same across jap and UK spec engines as i don't really want to get half way through this swap only to find that they are different somehow. Also to swap the heads over i'm assuming that all i would require is a head gasket. I cant think of any other parts or gaskets that i would require but if someone has any further knowledge please let me know.
Secondly is there an easy way of blocking off the oilways for the oil cooler as i don't have the cooler and would assume that they're like hens teeth to get hold of?
If anyone can assist me on this i'd be very grateful. I'm going to call the yard back tomorrow and speak to the boss so i'd like to be armed with info about whether the above points can be adressed or whether i'm better off sending it back to them and trying to find a replacement lump.
Thanks
Rich
p.s. If UK spec engines are really rare let me know as i'd be up for a swap to the japanese spec one! Comes with carbs also.

You have it easy mate.

Heads are the same and the oil cooler rad is easy to get hold of (or any oil cooler rad)

you need a head gasket and the pipes and fittings for the UK block - you can get the fittings from any hydraulic shop, or poss from Honda as am pretty sure the NC24 pipes and cooler are the same fitment (and so will many other bikes)

no worries! :mrgreen:

ideal.
Thanks for that.
The engine seems to be a lighter colour to my old one. Hopefully no one will notice!
Will see how the fitted carbs go and if they're alright i'll have a mint, 100 mile old set of carbs from an rvf for sale soon.
The pipes came with the engine so hopefully i'll find another rad on ebay. Are they all the same size on hondas? Having had a quick look about i think the fittings will fit almost any honda rad but didn't want to get something too big or small to fit!
Cheers for the help
Rich
