set of b12 crankcases soda blasted. studs soaking in pen oil. will remove tomorrow. first job will be to bore the mouths to take the larger liners. then remove all the casting flashes from inside and open up the galleries between the cylinders for better balance breathing. then remove the oil blanking plug from the lhs main gallery and tap to provide an oil feed from the bottom end to the head for that side. im predicting that opening up the mouths will cut through the oil galleries on both sides so i'll tap and grub screw them so its totally dry blocked.

removed the rest of the studs and dowels tonight. little bit of rust thats not supposed to happen. great success. ready for the next step. because of the way the crankcase is cast, there isn't complete location of the liners in the case, which makes centering up on the bores interesting. what i'll probably do is machine a boring plate which locates using the two dowels in the case and means i can clock up the bore centers dead easy. also means i can probe the face to make sure its dead level with the bed.

did a bit today. it always annoys me how time gets eaten up by nothing. all i did today was cut 2 busa spindles in half, face them off, machine a plug to go in the middle, weld them together and put the wheel back on. and suddenly 2 hours was gone. gonna get the plenum finished tomorrow

bov welded onto the end of the plenum piping from the turbo to the plenum is finished. i'm not particularly happy with the plenum, its a bit wanky compared to the quality of the headers. it'll do for now, but i'd like to make a better one with some laminova interycooler things in it. i can probably do another one which extends backwards between the two frame rails to house the intercooler and bring the boost pipe up through the subframe. instant battery box, just add weld fits nicely out the way airshifter sort of fitted, just need to make a pivot for the other end. gonna prep the throttle bodies (plug + epoxy the secondary butterfly shaft holes) and machine the inlet 'rubbers' for the nitrous foggers tomorrow.

indeed, i think an rm250 gear lever should fit on the outside of the arm thats there now and allow me to manually do gears.

tapped the tb's for takeoffs ( map + bov) foggers in its pretty much ready to fire up again, bar strapping the plenum and tb's to the head.

Hi, I love the way you're doing this project, but why no o-ring on the manifolds?
grts, Bert

there is a 4mm piece of composite heat shield board between the head and manifold.
being as they are both machined surfaces and there is some conformity in the board, they should seal fine.
