Pistons and rods installed. Just waiting on a set of STDX King rod bearings to make some adjustments to my big end bearing clearances…. Unsurprisingly, the STD size bearings EPR used produced 0.0017” clearance not the 0.0035” quoted in the build sheet. Targetting 0.0025” for this build. Also reinstalled the @brettdempseyengineering oil tree. Oh and I will never use a ratchet piston ring compressor ever again, these ring compression sleeves are SOOOOO much easier to use!!

Crank back from OCS and happy to report she’s straight as an arrow with less that 1 micron of runout. went with Torco MPZ assembly lube after numerous recommendations from engine builder friends of mine. Main bearing clearances came up nice and even at 0.0026” give or take a couple of ten thousandths, and the crank spins over nice and smooth

May have missed it, but what turbos are they?

New bearings arrived Now waiting on the crank to come back from OCS. I checked the run-out and while it was in Nissan spec (0.0039” limit!), it had too much runout for my liking, so OCS are straightening the crank to get it as close to 0 runout as possible

If in doubt, count teeth on the belt between the marks

Very very true

Well a rather annoying twist in the tale. Installed the crank the other day after completing all pre assembly prep. Everything seemed ok bar a slight bit of clearancing needed on the girdle plate. Took everything off and found a whopper of a scratch on one of my main bearings. Annoyed doesn’t come close! I know the block and crank were crystal clean so I can only assume that my old pot of assembly lube had become contaminated with a bit of grit or who knows what. What are the odds?!? So, yet again, a thorough clean of block and crank before sealing away on clean bags while I await new bearings to arrive….. and a NEW bottle of assembly lube by @torcousa via @nimbusmotorsport

JWT lifters??? Are you sure about that?? I can’t find any trace of JWT lifters on their website or anywhere on the net

Block prep is now finished. Primered and painted in VHT Cast Iron Grey and new freeze plugs installed. Picking up a set of micrometers this eve to take post micropolish measurements of the crankshaft and then assembly can begin!

Make the Hour drive to PowerZed in Bristol mate

UPS are awful for importing stuff. I insist on fedex every time I get stuff from the states, never had a problem with them and import duty is paid on your behalf and then you’re invoiced after delivery

Well after a 6 week intensive course with work, I’ve managed to collect my rotating assembly from OCS. All balanced up to 0.1gram. Dropped my heads off to get a suitable surface finish (unlike the 127ra finish by EPR!) so they should be good to go in the next week or so. Still waiting on block paint and freeze plugs to be delivered, then I can start the assembly process

Take some time off work this week, so enjoyed the day cleaning and degreasing a variety of parts. Engine block is now ready for painting (hopefully paint will turn up tomorrow). Donor Crankshaft cleaned up really nicely, and pistons and rods are also ready to go. Bloody love Bilt Hamber Surfex HD degreaser, by far best commercial degreaser on the market in my experience!

Bought them from Performance Unlimited. They’re the UK approved retailer. 88mm CP pistons. I had to give dimensions of rings as well as my anticipated power/boost pressure, that TS then matched to their products to spec the rings
