Do you not have access to an electric soldering iron?

Darryl

22

He’s got gas

23

Yep, posh gas one!

Will be it’s 1st use. Appear to be out of solder so off to Mr B seniors to nick some of his. And his wire strippers. And his heat shrink

Excited.

24

Leave the cables nice and long on the old plugs just in case you want to convert back

25

Got all the injectors out no probs, and no bits lost!

Just sat by the door waiting for the postie

26

Oh the excitement, I would suggest putting the injectors into the inlet manifold\head first to make sure you get them in the cushions properly apply a little lubricant to the the top portion of the injectors then fiddle the fuel rail on, when I say fiddle I mean it. If you do it the other way round there is no way of telling if you have tucked the injector cushions in with the injectors, I know I’ve done it, you get a very strange fuel smell when you use the loud pedal but not any other time…

27

A bit of silicon grease is the best bet for lubeing up the injector seals

28

Thanks Both.

Ade, now i’ve got them out I decided the same method as you.

Will use some oil or vaseline on them to esnure they slide in place, rahter than slide off!

Delvery truck not here yet

29

Oh the suspense, I had to wait a while for mine with no car as my ECU was in the US, god it is hard

30

Ade,

I have some confusion!

The RC ones turned up as per pic below. They have the upper O ring seal on them already, but nothing on the bottom to seat into the engine hole.

I spoke to Sinc’s and they said I don’t need to use the lower seal from the old ones, on the new ones??

Doesn’t feel right to me as the new ones are just hard plastic. The old seals must have to go on, surely!

Help!

You have a PM

Hi Ade, PM replied!

Here’s a pic of all the original injectors on the rail.

I used the seals from the old injectors, and then cursed and sweared for a couple of hours trying to get them in / get the rail on!

In the end I cheated

I put them in the rail and lowered them onto the block, with the seals already sat in the recesses.

I then used a borescope (perks of the job) to check they were seated correctly as you just have no idea otherwise - and would have fuel pissing everywhere onto a hot surface. It came in very handy!

Pic of one of the seals at the bottom of the injector, on the borescope!

I found it too tricky to put the injectors in the block, then put the rail on top of them

On the plus side I didn’t lose anything down the engine bay!

Installed the new ECU and just got to do the soldering in the morning

33

There is no need to solder the new plugs if you don’t want to, you can get adapter plugs from RC that just clip on the the injector and the oem loom plug.

34

Hi Middo - that would be great but Sinclaire’s told me you can’t get them??

I’d much rather use adapters than solder.

Edit - guess some more mis-info from Sinclaire If I knew these existed I would have ordered them up front and saved me a day. Think I might have to order these…

35

When my car was done these convertors were ordered , came through with incorrect fittings twice, so made the choice to cut the cables, if you cut and solder it is still possible to revert back.
I see the only time you would do that is if you sold your ecu and new injectors in a swop with someone.

36

Or if you return the car to standard before selling it.

Wouldn’t be so much simpler if you could just get a remap through the diagnostic port

37

Is that an option, Damon?

I’ve finished the install now - just got to test it.

It started fine, no CEL / MIL and idles just fine. The ECu will need to learn it’s fuel trims which will take time. My main aim now is to ensure there are no fuel leaks, and that the AFR is healthy. Dyno tomorrow now…

38

Ok it’s all finished

Been out “testing” it this evening on some roads I know. It’s significanty quicker Some of the roads are tight and twisty and the traction control is really having to work. Not been brave enough to take the control off yet Probably need to do something brake related now too.

It doesn’t feel like 30-40 bhp but it quite probably is - just the nature of superchargers makes it feel progressive.

I will post up some bullet cam footage of the speedo tomorrow

All in all, it refreshed my dislike for working on cars, but glad I did it myself as I know exactly what’s been done to it.

39

Congrats

Looking forward to dyno, where are you having that done?

40

Triton in Bournemouth - rally outfit but they have a Dyno Dyamics dyno which is the only make I trust!

It’s more for the AFR tbh, but will try and get WHP and ATF figures.
