I've moved on a little more but still waiting for the new fuel line to be made up.
The OMG back box is on and I must say that the fitment is bang on, it may have some thing to do with the development down pipes being a near perfect fit (unlike the original system which never fitted right) Bumper back on.
Also fitted the Piper X induction kit which I must say is the cheapest piece of junk I've ever used just hope it sounds ok b4 it falls apart, not impressed.
I'm having a few problems getting the near side rear caliper back on though no matter how much I screw the piston back it wont fit back over the disc, the other one was tight too. This I fid odd as I've done the rear pads b4 with no problems.
I will be getting Andy to put a few more pictures up soon too.

Update
Back brakes back on.
The Plenum top is back and looks like a nice job, (Bedford Body Shop in Wellingborough Great guys)
Throttle body fitted and wired into the mk1 harness and ECU tested seems fine, fuel pipe and unions sorted thanks to Webster engineering in Rushden northants drag race guys who are also a Motec agent too.
Had an issue with it starting disscovered 1 knackard coil and 3 shagged injectors so I have fitted the bigger ones I was going to use originaly. I havent tried to start it up again yet as I am now waiting on a PTFE gasget set.
Still need to bleed the clutch and power steering system plus remove any air locks in the coolent system.
And then should be ready to get out and get an MOT.

To be hounest I had my Renault 21 Turbo Quadra chipped at super chips years ago, and one of my friends saw it take off over a mini round about while they test drove it.
I called to complain and was told they do have to drive them quite hard, YEH RIGHT hard but not like a C***.
Didnt make much difference either.

Weekend over progress report.
Right then as said b4 identfied the faulty coil and replace, tested cleaned and fitted the bigger injectors. removed the yellow ones and binned the 3 dodgy ones.
put the inlet all back together and it started but runs bad missfiring, traced it down to 2 injectors not fueling. Ive proved the injectors are OK by swapping the lead from one firing and the injector fires fuel, put the lead onto the other injector and it doesnt.
Ive traced the leads all the way back to the ECU and they all bell out fine, the grounds on both leads are good too plugs are making well get the right reading at the ECU from the injectors.
My next step is going to be putting my scope meter and look at the output of the ECU and compare it with the working outputs.
I was concerned that the knackard injectors were reading a direct short, but would expect there to be some form of protection on the outputs of the ECU.
Oh had a slight water leak to but it was just a oring not seated right, throttle body seems to be fine nice control with the peddal.

Until the missfire problem is sorted it wont be out, I cant load owt on the work PC and as my laptops buggered cant upload any pictures yet.
Fingers x its just something daft Ive missed so Im retracing my steps to see where its gone wrong, like I said I would have thought that Bosch would have some form of blocking diode in case of a direct short.

Simon, something I found a while ago relating to Bosch ME 7.4.6 injection ... You maybe have the manuals already ...
Bosch ME 7.4.6
I know it a diesal implementation but there are diagnostic sequences and OBD codes for injector failures you might be interested in ... Pages 129 & 236

Cheers Martin will have a look.
Ive got to the point now where Ive replaced the injector harness with a spare even though it all belled out OK, then unplugged each sensor one by one to see if it makes a difference.
Even tried my spare ECU which does the same, it still aint firing those 2 injectors, I am going to put a link accross from one of the other injectors that fires b4 it just to get fuel down not ideal I know but should work.
Any other ideas would be most appriciated.

Right then I think I may have sorted the injector problem out. (but dont realy want to talk about it)
I will be putting the inlet back together tonight and see what happens.
Got some PTFE inlet gasgets from a guy on here but I had some concerns that they wouldnt seal right and I think Im being proved right, so back to the OEM ones me thinks as I dont want to have to use sealer all over the port inlets. Shame realy lot of work gone into them but they need to be sealled right of fuel will piss all over the place not good and leak air.
