SDI Injectors

not sure which was used Pete in honesty - i think it was in an ultasonic bath too, but not 100%.

Matt cleaned them up before he popped them in!

Thanks Pete, bit more involved than my old baked beans tin and a bit of white spirit, have to get them done professionally done, if they need it.

Pete, with the amount of smoke that I've seen you talk about since fitting SDi's, I just wondered: what boost pressure are you running at?
If you're not sure and don't fancy cluttering up your interior with a boost gauge, this is a really good solution for finding out:

Mine was only running at about 13PSI, so was smoking quite a lot because there wasn't enough air getting in to burn all the fuel. Shortening the actuator rod to up the pressure to 19PSI made a massive improvement to both power and smoke levels (1st up, 2nd down)!

Cheers for the info, I'm off to Yeovil tomorrow for a Reidy Remap, we did mention boost pressures and hopefully it will get sorted out on the RR.

Will be interesting to see what its running, the smoke is only when you really boot it, and its only for the initial kick.

One of the guys at the meet yesterday said that when we went by him it wasnt bad, just a bit when I accelerated away. He was the red ZR, with green MG stickers, just had a new head gasket and was taking it easy.

Dont want to kill the fuel pump, or my CHG, as Pete with the tuned derv, says too much power can ****** them!!!! ( )

Let you know later what happens down at Yeovil.

Well done, might be worth looking at the bleed off pipes.

Easy to do at the same time, if they look a bit worn.

My local shop gave me a kit for a Vauxhall. Seems to fit OK.

The injectors just need a wiggle and a pull straight up to get out. Thats after taking off the clamps at the bottom.

I spent 10 mins winding No1 round and round as it felt like it was screwed in!!!! Doh.

Take care of the wire from No1 injector. Also be careful how you unclip the wire from No1. where it goes into the brown plug and socket connector. I used a small screwdriver to pull the spring clip off, did it too well and it sprung out and disappeared, luckily it fell down onto the foam undertray.

Squeeze the fuel bulb to put the pressure back. I didnt crack the injectors, just cranked it over a few times and it fired up.

I'm keeping my old injectors just in case I dont pass the smoke test on the next MOT. If I also have to refit my cat as well, I'll be rebuilding the car for each MOT.

Got a price of £95 for refurb on the O/E injectors that came out.

Good luck with it.

You'll love 'em!
But you don't necessarily need to clutter up your dash with a boost gauge - check here: http://tuning-diesels.com/Lseries/2545.htm
