So time has come to start this thread. Quick summary: Bought MS6 Bought more MS6 (broken one) broke MS6 It became the donor. Now building new MS6 Background: The grey MS6 was my daily for a while until the VVT gave out. At that point, I decided it was time to build the clean (red one) and scarp the rusty grey one (I couldn't even jack up the car from the rockers anymore). I bought the red 07 with a blown engine, carnage: The PO was an old lady too so im not sure what she did, but she sure did enjoy the car. On to the build. I decided to buy an engine with a spun bearing and forged internals (because who had enough engine parts??), salvaged some Manley H beams and some supertech pistons. That said I needed to bore out the cylinder walls so I got some brand new 88mm supertech pistons matched with the H beams I salvaged. I wanted to get an S4 but edge was out of stock, they said BNR wasent able to supply the S4 so i decided to get the s3 instead with the expectation of swapping it out later on for a bigger turbo. For now I dont plan on upgrading fueling until I get the build up and running. Since this is my first time, I dont want to get ahead of myself just yet. Got the block and crank machined and build the lower block a few days ago. I wasn't going to delete the balance shaft until i saw what reinstalling it entailed. Got a BSD kit from JBR with the baffle. Now im just starting to work on the head. I got the deck resurfaced at the machine shop and wasn't planning on taking out any valves until I saw the valve seals in the rebuild kit. Decided I might as well clean the intake valves while I change the seals. I dipped them in some engine part cleaner (greez off) for a few hours. It took most of the carbon off but I still have some valves that are cruddy so Ill probably dip them in for a little longer and scrape off the carbon with a brass brush. I did notice one valve has a small dent in it though. That said the dent is only on the bottom and dosent seem to affect the sealing surface ... Any thoughts on this? Anyway, once the intake valves are cleaned, i plan on putting them back in without lapping them. The machine shop did a vac test on the exhaust with good results so i doubt lapping them will change anything. Once thats all done, hopefully soon, i plan on putting the engine in with a cpe tmic and some damond motorsport mounts. Im still debating on the dp (ebay or not). I know ill be going catless since etests are banned here. I know ill be using the magnaflow cb from the donor. Hopefully Ill be able to make decent power with this until I decide its time for some pi and meth.
