Right, a little recap for those at the back.
Engine is back in and running, built up in true pikey fashion. Meg 250RS rods and pistons, Cometic 1.9mm MLS head gasket. Modified 172 cams, 19T hybrid and 250RS injectors (got some new 250 map sensors to go in at the time of mapping too) Slapped in a new CG Motorsport race clutch to replace the dual friction one that was in there (no issues with the old one just wanted to make sure it could hold some more power). Ran in on millers running in oil and now on some more millers CFS. By the time its gets to Chris on Wednesday it will be up around 750 miles since putting it back together, fingers crossed if it was going to go wrong it would have by now 🤷♂️ I'm tempted to ask for the torque to be kept relatively low if possible and just hold it for as long as possible, this is banking on the cams actually helping push the power higher in the rev range. Its been a pig to drive in traffic as it currently cuts out when pulling up, so putting the miles on has been fun, luckily I live about 4 miles from a quiet motorway which I've been up and down a fair few times now 😆 so I'm looking forward to being able just to drive it normally again
I've cleaned up the bay a little also, relocated the brake/clutch reservoir to inside the car under the dash and used the freed up space to fit a breather catch tank rather than my normal pipe to somewhere handy. A new lambda was thrown in as the one in there was seemingly causing some issues where it would pin the ecu fully rich or lean. There was also a problem using the cooksport rail with the 250rs injectors, the retaining clips don't fit it, and the injector itself is slightly narrower than the r26 item meaning it could fully plunge into the inlet manifold and come out of the rail. I did actually call cooksport who claimed that they never had the same issue even without the clips, said they would call me back but never did... there was someone else on facebook with the same issue running the same style of injector. Anyway to cure the issue I had a friend from work spin up collars/spacers to sit on the injector, this stopped them being able to push into the manifold and when the rail was bolted up held them pinned in place. So far so good, hopefully they still work fine under high boost/fuel pressure.

I've spent today prepping it ready for tuning, set the wheels straight on a friend ramp, one of the track rod ends was a bit seized, but nothing a bit of heat and some mole grips couldn't sort. I've actually set it quite conservatively to normal, -1.3 camber and about -0.05 toe out, plan is too see how it puts down the power and then ill adjust it from there. Plugs cleaned and checked, gaps set at .6mm.

Anyway its time to play the guessing game again, What are your predictions????
