A very smart looking Mini

[bajean]

Quick Update on the mini. Finally bit the bullet and bought a brand new set of twin hs4s to go temporarily on my 1275 but will then end up on the 1293. Will be installing them tomorrow along some other goodies.

Today I installed the twin hs4, got it to fire up and idle at 900 rpm but still need to set up the fuel mixture, but hey at least it runs ?.

I also installed a braided oil pressure line and relocated the oil cooler behind the grille for a cleaner looking engine bay ( switched from a 13 row to 10 row, which will still do the job just fine ).

The next thing on the list is to sort out the wiring as its a complete rats nest.

Finally got everything ready to start the engine build. Gave a block a really good clean up with some acidic cleaner and took it to the machine shop to have it, bored to +0.020 over, line bored for the KAD steel main caps, installing new cam bearings, installing new threaded oil bungs and drilled for 11 head studs. Having done all that i will dry build the engine to see exactly how much to remove off the deck of the block to achieve my 11:0:1 CR. Really looking forward to this !!!
