x18xe1 block and e16se head help??

[Nailen]

i recently blew my 1.6 8valve rally spec engine and thinking about an upgrade. i had the idea in my head of using an x18xe1 small block 1800 and my e16se head. kinnda like the ford zeevh with a 2ltr zetec block and 1.6 8 valve head. has anyone tried this and could shed a little light on some things..

Im just going to bore out the E16 block to suit the pistons as I dont think the oil and water galleries match up

[Nailen]

how you been planning same thing bazil??

[bazil]

Aye mate, crank fits the block anyway so just wap the crank rods and pistons into the E16 block, I was told the maximum bore limit on the E16 is 82mm the z18 pistons ( same as x18xe1 ) are 80.5 iirc also the crank uses a 6 bolt pattern for the flywheel so its all good

[Nailen]

brilliant thats it decided then am building one :)

Thread about it from a little while ago mate

hmmm still abit baffled i dont want low cr as am not turboin it so can i just bore mine then fit 18 internals?? do i need to skim pistons then?

[bazil]

You shouldn't have low cr mate but valve clearance is an unknown as of yet mate

[Nailen]

I can sort valve clearance easily though. Time to put plan into action I think I have a x18xe1 in the work

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.

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)

[mowgli]

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.

[Nailen]

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 :-)

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" lol

[mowgli]

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.
