Ok nearly finished my turbo project and looking onto the next.

 

Been looking at different engine conversions but keep looking at the k1100 head.

 

what work is required to carry it out? Head and block work machining? 

 

I have a 1275 and 1293 engine in my garage doing nothing. 

 

grateful for any links or advise on start to finish builds.

 

Cheers

Not too sure about the k1100 conversion but if you've got the funds then the KAD twin cam looks good.

Force racing do K1100 kits, contacting them would probably be a good start on what's involved

I've just finished a K build. I'd suggest getting the SC build manual. For the sake of £20 it's very useful.

..and i believe that they'll refund the cost of the build guide if you then purchase one of their kits

 

https://twincammini.com/ documents a conversion reasonably well, plus there's quite a few build threads here as well

DO IT......

I know someone who has fitted a bmw head to an a-series inline. I can ask for details but pretty sure it involves blocking and redrilling the head bolt holes at least.

Great I’ll buy that for £20

Yeah any help would be great

 If you are going to do it yourself rather than buy a kit, you need someone who can weld alluminium and someone with a milling machine.

[simplyminis]

Yes I have acsesss to all that

[DeadSquare]

Buy 10 (4 spare) high tensile 3/8 UNC  2" bolts, with plenty of shank, and with die set as wide as you stock will allow, thread a bolt on down the shank.

 

If you have one, an old Whitworth die is best, as they cut a more tapering thread.

 

Having cut the thread on down on the first bolt, cut off all but a couple of the original threads and try it in the block.  It should bind at the third thread, so adjust your stock until it is a tight fit.

 

If you are engineer enough to have a milling machine, you know what I'm getting at.

 

Clean the threads in the block in the usual way petrol, jizer, water, meths and screw your re-cut bolts in with Loctite 270.

 

Use your milling machine, not a pillar drill, to re-drill the block for the re-positioned head studs.

Checked with him .. he used the SC guide,

[Shooter63]

I've got the manual and to be honest I didn't think a lot of it, in fact I found better info on the ausmini web site, I've got the head, a short engine etc just need the time to start it. I think there are better ways to do certain things than the book states.

Agreed. But as a reference and an overview of what's involved I think it's worth the £20.

OI think the guide was well worth its 20 pounds, some info is out of date (cam lift for example) and there are many ways to skin a cat. 

 

But for a novice like me the guide was great

Matt Read here in Australia is highly recommended. He has done heaps of them and sell kits with good instructions. Worth looking in to.
