x18xe1 block and e16se head help??

[mowgli]

the main issue is with the oil pumps. the 1800 has a larger one, apparently. i only found this out recently, after i got hold of a crank, pistons & rods.

Tbh id of thought using the 16se block, the 16se pump will be fine also. Could always fit a few washers behind the relief to up o/p or fit some steel pumpgears if going to be reving it quite high(above 7.5k)

no, its more to do with the size of the 2 flats on the crank. i'm trying to get a pump at the moment to find out.

i managed to get a block in work and done loads of different things but i am using full xe1 bottom end with my e16se head i had block 3 oil galleries and i have got a gasket coming that will block 2 water galleries and ill have to ma a new engine mount but apart from that i think am good to go :-)

Just plasticine on the crown and dry build, if you need to machine some pockets so you have you 1-1.5mm piston-valve clearence then should be sorted. 1.5mm is more of ano ideal but i know lads who run 1mm on rally cars.

I know someone who phoned Cosworth for advice on a build as he only had 10 thou of clearance... their response was "so it clears then"

seems fair enough

Only just read this, 1800 pump fits but you have to shave a bit of the block away for it to sit flat.
