I would add that a well done map can help reducing a bit of smoke (expecially on low revs..) and not only to give more BHPs..

Can anyone suggest the best place to get a set of sdi injectors for my 45?

Would it be best to get them mail order or from a scrapper?

And waht should I pay?

Cheers


Jonathan

Make sure they are sdi injectors ie 200bar. As quite a few ebay sellers just list them as diesel injectors which YOU ALLREADY HAVE and are from 25 ,45,......

Excellent info chaps - thanks. Can anyone confirm their mpg before and after fitting these, either with or without a remap? - thanks.

Why SDi

Why are these injectors better?

Perhaps the question I should ask is; why would Rover have changed to a lower performance injector?

(Or have I misunderstood as I'm a bit of a novice but looking to improve performance)

they offer a lower break pressure allowing more fuel through, but they dont have as fine a spray pattern which makes them heavier on emmisions and economy

D'oh! After buying injectors, preparing to fit them today, I realise I have forgotten new washers. How essential are they?

Also, as they are used, should I attempt to clean them in some way before fitting?

Washers are very essential. Go to a Land Rover dealer and get them, ask for Freelander L-series engine injector seal washers.

Do not attempt to clean them yourself, professional only job.

Anyone fitting SDi injectors, remember this, your boost will be raised by about 3 psi due to the extra fuelling, so if you've already raised your boost you may have to turn it back down.

What sort of difference to the 0-60 does this make on the 99bhp diesel?

If you are just putting in the sdi's i would say it would be running around 125 - 130bhp. I would guess the 0-60 would be around 8 - 8.5 (standard on a 99bhp is 9.7) but not 100% sure as its just a guess. The torque you gain is the best part which makes overtaking really easy.

I think mine (152bhp 250 lbs/ft torque) is running 0-60 around 7.5 but again just a guess

Anyone know how much it costs and where I can get it done to have the injectors professionally cleaned/refurbed?

I'd estimate about 135 bhp.

How much difference do they make to economy? Does the mpg drop a lot?

Cheers

For me I estimate around 2mpg in town and on a fast run, on a gentle run maybe 5mpg (when less fuel is used anyway, so it only takes a small increase in fuel use to drop the mpg quite a bit).

This is all guesswork though, as I had a ZR before without SDi injectors (but remapped), before the ZS with SDi injectors fitted but not mapped. The ZS weighs a bit more but is more aerodynamic, so it's hard to know exactly how much of the reduced mpg around town is due to the extra weight compared to the ZR, and how much down to injector differences. On a run I haven't hit 60mpg with the ZS yet (only 57mpg, but I've done less long journeys driving sensibly in it), but on the ZR I got over 60mpg twice (64mpg and 69mpg).

Taking into account that remaps to gain 140bhp or there abouts on standard injectors will put extra stress on the fuel pump, I can live with slightly less mpg's with the SDi injectors, as they are not stressing the fuel pump as much, and cost me less than half the price of a remap.

Bang for buck the SDi's win for me, but if I was doing high mileage then I would consider a remap instead.
