make sure to get DLC washer for your timing sprocket, it will prevent slipping at high rpms. Flywheel doesn't need that since it has 8 bolts preventing it from slipping while timing sprocket has only the keyway (it will turn freely once keyway is gone).
I would also be very apprehensive about running anything over stock thickness HGs... in my mind, any foreign metal between block and head is just a way for pressures to work its way through there and causing HG failure. More of it, easier to leak...
As to WM. USing the flap output seems kind of binary and lacks precision. I will be converting my system to use IDC (injector duty cycle). That is the most accurate way to control WM injection since it will directly correlate to amount of fule injected. MAF input is not accurate since MAF flow to voltage is not linear.
Conversion will involve making fairly simple board to convert input 12v to 5v and then PWM signal (which injector on/off is) to 0-5v voltage. Three electronic components total. Output of this will go into standard WM controller (Vast in my case) and there I can adjust things with pots.

I think you will be good to go. Block failures arent as much of a thing as some tuners want people to think.

from what I can tell 2.7t block failures are rewards for doing something very very dumb in the tune.. generally, running too lean, too much timing, oil supply failure, stupid EGTs, etc. the 2.7t block is DAMN stout in stock form. |

I hate those. More power to you for messing with it. I have one I bought for myself and after doing a few for customers I was over them.

Dude, it was a nightmare. Cutting the oilpump, cutting holes in the pan (which I am STILL waiting for from my welder). I would not have done it had I known what a PITA it would be. |

8500 rpm is borderline for a 5/16 inch arp 2000 with heavy rods and pistons.

It's a eurospec girdle  SRM makes one as well, or I have another 3.0 shortblock already girdled and ready to go if that sort of thing interests you. The machining and setup for the girdle is hell. Modifying the pan alone.... |

Why do you want to use RS4 Cams instead of 2.8 Cams? Think about 2.5TDI Oilpump  |

There is no such thing as RS4 cams. RS4 uses 2.4 NA cams.
