1972 Rover P6 2300TC - Saab B234 Turbo

Not really a fan of the all one colour look with a bulge, and I'm used to it being black in the middle anyway!

So with the decision made I've put a first coat of black over the centre of the bonnet. Not sure if I should leave the middle of the bonnet at the front going into the scoop black or keep it blue?







Also painted the rear lower valance and got the rear end going back together









The rear wings are giving me lots of trouble where I've moved the wheelarch up but are getting close to being ready for a coat of lacquer at last. That'll leave just the bonnet to finish, and to start the lower front valance and doors.

Very nice.

The clock is ticking to get it ready and running properly for RRG and it's just too hot to paint recently! See what happens over the next month but I have started smoothing out some of the blemishes....



The power steering pump bracket has been welded up, painted and all reassembled





Got the front valance painted and fitted







Due to going bumperless I need a rear number plate light. After a lot of thinking I bought a cheap pair of trailer number plate lights, made some spacers and screwed them on. They need a little extra shrouding to stop it looking like I've got reversing lights stuck on!





And then a huge hurdle was overcome, getting the little Rover out of death row!





The front air dam has been fibreglassed and now screws on so almost done



Lights, windscreen wipers and washers all work too



The last big job is to get the engine running properly, which means tuning the Megasquirt. I've been fiddling with some settings on and off over the last few weeks so it starts happily from cold, runs upto temperature, restarts when hot, and revs freely. I do however have some issues which I'm struggling with, and that's an erratic TPS signal only with the engine running and the afr wandering. First thing I checked was all of the earths, and they were good, even adding a second engine earth strap. The battery voltage is also slightly erratic by about 0.4 volts so I'm beginning to think it's a power supply issue with some electrical noise getting through. I'm now in the process of moving the EDIS wiring away from the ecu loom, and fitting capacitors wherever suitable to help clean up the electrical feed to the ecu

This thing is looking as awesome as ever, hope the idle issues are easy to sort

Thanks . I'm still struggling to figure the idle issues out, just short of buying another idle control valve and chancing that? It periodically works perfectly, with an acceptably stable afr, but then starts hunting again with the afr wandering. Got a few more things to check and some other settings to try on the ecu. Fuel pressure is stable at about 38psi, until it begins hunting and the pressure rises and falls with the manifold pressure changes on the stock Saab fuel pressure regulator.



Thanks

Interesting stuff, mostly over the top of my head but I can kinda get some of it! I should have a few spare IN4001 diodes that I can splice into the loom and see if it makes any notable difference? What makes it more annoying is how my 'squirted SD1 has the stepper motor and that works as good as the original hotwire installation, yet I'm struggling with a simple on off valve with 2 wires!

I did have it on warm-up only, but it was worse at the time I was last trying it. There are surely some other underlying issues that I haven't figured out yet, and putting it on closed loop seemed to help enough for it to run noticeably better. If I don't get any reasonable improvement over the weekend I'll bypass it entirely and try to get the base tuning done without. I've recently bought a noise suppressor aimed at audio installations which I can patch into the power input to rule out electrical noise coming from the alternator?

I've stuck some sheet rubber over the top of it already, it's low done and vulnerable and will inevitably get bashed so some rubber will resist and hide most of the lighter scrapes

FORUM VICTORY!

You're bringing this to RRG right?  Can't wait to see it!
