Bit of an update on things with the engine rebuild.
After some discussions on line and some wisdom imparted from Prawn I decided to bin the idea of keeping the standard pistons and get some aftermarket forged items. Although I believe the standard pistons would work in the short term they have already done 90K miles and the bore etc is not exactly factory fresh.
So bought some Wossner 9.5:1 82.5mm pistons. These are the same as what Prawn uses in his car and that's currently making over 500bhp so they can't be all that bad. At least until they wear out
.
With this size piston capacity increases from 1780cc to 1850cc so another 70cc capacity which all helps.
Found a place to do the rebore work I thought. Dropped the block and pistons off last Monday and was hoping to pick it up last Friday. Rang on Thursday last week and told that machinist had been busy and had not had time to do the work. He was not going to be in this week so work wouldn't be done till next week at the earliest.
Slightly annoyed as I could do with putting the engine back together . Anyway rang on Friday just to check something and got transferred to the main office. I am now told that the place I took the engine too which is part of a larger group of companies is being closed down???.
They are still going to honor the work but I am not entirely sure I am happy with that, however I can't find anybody else locally who I think could do a better job than them.
So hopefully awaiting to get the block back next week sometime so I can start rebuilding the engine.
Head is all built up, ready to go on. Rosten uprated springs, new exhaust valve guides, supertech Inconel exhaust valves.
Did a very small amount of porting just cleaning up some of the rough casing marks at the back of the valves and removing a bit here and there that was obviously in the way.
Wrapped the manifold and down pipe to try and reduce the underbonnet temps a bit.
Filled the engine mounts with liquid polyeurethane. Went for the slightly softer 60 shore stuff. Not completely solid it allows a very small amount of movement.
Bought a tool as well so I could get the crank bolt undone. Jeez that's tight. I really would hate to try and tighten or undo an ARP item.
Bought one of the diamond coated washers as used on the 2.0 TFSI engines for when I put it back together.
