I put mine back together and drowned it all in new engine oil, then took, er, a few weeks to actually get to the point it started  no, a few weeks? think I had 2 birthdays in that time  Rich. [insert inappropriate joke about alzheimers here]  |

He was too busy posting on here to get his star rating up, no time for cylinder heads.

Looks good!
Where did you get this done? Just a 30thou a skim in the end?
I went 20 thou skim in the end, straight swapping a BP4W reduces compression from memory. Skim was carried out by DGilmour engineering. This leaves me ok to go forced induction in the future. The valves were re-cut by Ross at West of Scotland Engineering, they recut the valve seats and reset all of the shims accordingly, as well as reassembling the head for me. I'm just going through the process of applying assembly lube as it won't be fitted straight away. Managed to get your hands on one? Ah ok, makes sense if thinking of forced induction later. Looks like a good job - from a photo! I got my hands on a complete vvt lump instead... Might still look into a BP4W head though. |

I think the only reason folk went BP4W on a VVT bottom end is ECU's couldn't control VVT, but they can now. if you go aftermarket ECU can you stay in the same class? |

The VVT was more local to you than me! Just found a guy breaking a MK2.5 in Hamilton and offered to stick it on a pallet.
Yup I'm not running it with the VVT working, we're only allowed stock ecu's and I didn't want to fit a controller or the whole 2.5 wiring loom.

I do keep wondering about a mk2.5 bottom end but I've no space/lifts to do the swap at present. If you run the BP4W would you run the VICs or go with the flat top mk2.5 inlet? |

I'd go with the flat top. Again the vics wouldn't work with the mk1 ecu or would require a separate controller. As you say the vvt bottom end with bp4w seems a good option if you can't use the vvt. That was my thinking for a project at the end of the year but with corona hitting and not being able to get on track I thought I'd just throw in the vvt for now |

Yeah looks like there won't be any Motorsport till September, plenty time to get it swapped! |

Anyone with a Mk2 1.8 (non-VVT) able to take a couple photos for me please? I need to check the routing of a couple things.
- Where does the injector harness earth mount on the rear of the inlet manifold.
- Where do the fuel lines route and which is to the fuel pressure regulator.
- Pressure Line to the top of the fuel pressure regulator, where does it feed from on the inlet manifold.
I'd be eternally grateful!

1. Mine goes to a nut on the back of the VICS solenoid
2. I can't say for sure as it is cramped in there, but I think the line closest to the front of the car goes in the bottom of the fpr
3. Mine goes to a tee right underneath the throttle body. Have a look at Carl S on Nutz, his thread has a different and potentially neater way of doing it

Have a look at Carl S on Nutz, his thread has a different and potentially neater way of doing it Thanks Corders, I think I have a threaded hole from the EGR for #1. I have the vacuum port on the top for #3 but I'd intended to use that for the Speeduino, I'll look into a T as there is a small length under the throttle body bit. Thank you! Did you have to transfer over the tiny temperature probe that goes into the head next to the rear coolant housing? Had a quick look and the BP4W has a blank fitted I think but I need to investigate. |

Yeah you need to do this otherwise the temp gauge won't work (it will just read max and scare the life out of you...in my exlerience ). Best to take the opportunity to get a new one too as the spade on mine broke when I fitted the plug on and it's a pain to sort with the engine in and gubbins attached |
