fill them up with solder, then drill to the correct size.

Normal solder I use for electronics?

I would have thought braze, not solder

prefer brase meself

Or braze 

[sassanach]

bog standard ordinary solder,works a treat

[sassanach]

sorry for the late reply,have just been to the local hostelry for a bit of female hormone replacement...hic!!

[sassanach]

if you try and braze brass that small you will have an unrecognisable lump of crap in your mitts....(after all braze is brass)

True... I hadn't thought about that

Sorry, I'm being dumb. Again.

Solder I use for electrical/electronics, or solder I use for plumbing.

Electrical solder will do a nice job.
I'd bung up one end with a bit of plastercean or blue tack then fill them up 

I don't know what engine your using them on but I drilled mine out too 2.3mm and i've never had a problem.

His car was the guinea pig to get the correct size for those nozzles Used to be 2.5-3mm on the older ones

[TheBoy]

Indeed. With the old red Valeks, we used to drill the nozzles to 3mm for 3.0/3.2l cars.

TBE was the first with the 'new' kit, and on advice from the supplier, drilled to 2.5mm, which is too big the the car to idle. We now know that 2.2 or 2.3mm is about right for 3.2l with these grey Motogas badged injectors.

Solder is a hell of alot softer then brass so if you have a pillar drill and a hand vice, i'd use that to drill the holes out.

If you hold the drill by hand, any change of angle could open the hole up by 0.5mm with ease and screw up the finished hole size.

It might be worth starting with a 2mm drill bit and then working from there

Agreed on the fill with solder advice.. Unless reducing the vapour pressure a tad would work? Think we did this on Melchet's one when it idled poorly on the new injectors.

IIRC it's only at 1.1 BAR anyway so I wouldn't want to reduce it too much

Indeed, it would be nigh on impossible to drill a 2.2mm hole accurately by hand.
