SDi injectors - Information for prospective purchasers

Following quite a few posts asking about SDi injectors, thought i would resolve a few questions.

Q What car are they from?

A They are found in all SDi/SD models from the following cars:
Rover 400
Rover 200
Rover 600

Q What cars can SDi/SD injectors fit?

A They will be a direct replacement into the following cars:
Rover 45
Rover 25
MGZSTD
MGZRTD

Q What are the approximate power increase after fitting them?

A Without a re-map, approx 130bhp, 200ftlb of torque (depending on additional mods to the car at the time).

With a re-map, approx 150bhp, and 240ftlb of torque (depending on additional mods to the carat the time).

When replacing injectors, always changed the copper sealing washers for new ones. These can be bought cheaply from places such as RimmerBros, or your local Xpart dealer.

Hope this clears things up.

If anybody else wants to add ant further info, then please do so

Would it be possible for a mod/admin to sticky this please?

Cheers
Dave

Yes agreed this could be very useful for some.

Is it worth adding that 130bhp is about what a car with the 99bhp map will get, and the 111bhp mapped cars about 140?

Don't forget you can always get the new seals from a Land Rover dealer as well...about 1.50 for a set and usually have them in stock.

Cheers,
Ben

I think we've had a couple of cars with the 111bhp map giving over 140bhp, there was Mel45 (149bhp?) and another one. I'll try and find some threads.

Added this to the list of Sticky's in that thread i made with all sorts of useful links. Might be worth somebody putting a link to the page on Rimmerbros with the sealing washers for the injectors as this is useful also

Cheers, James

Well added mate, but a lot of newbies still don't read that thread

Hopefully this one will get into the sticky section as well.

Cheers

Not much time tonight to look, can't find any SDi injector RR results. Hopefully Dakta can chip in with some of the data from his power database....

Obviously the lower the miles the better, but you can send them off to be re-conditioned, no idea how much that is tho.

I had my car (99bhp standard) RR'd before my remap with the sdi's in and it came out at 139bhp 215 lbs/ft torque.

It did have freeflow backbox, K&N filter & decat on aswell tho

Question

If i fitted a set of SDI injectors to my bog standard 45TD, is it likely to go from it's usual smoke free zone to looking like a 100 a day chain smoker ? Or is it likely to stay the same as in fairly smoke free ?

will probably start kicking out a fair bit of smoke with a set of sdi's, if you up the boost and fit the usual decat/air filter etc. it should clear it up a bit.

The streetwise smokes like a ***** tbh, however boost is standard. I've got a flowed inlet manifold to go on and i'm upping my boost soon so it will probably get rid of most of the smoke.

Mine with the 111bhp map is "acceptable" with SDi injectors - a quick puff of smoke in the rear view mirror when floored at around 1700rpm, and a light haze up to the red line. Boost at 18psi, ITG panel filter, DIY decat, no other mods. Turning the MAFAM right down helped a lot.

I would imagine a 99bhp map car would be better for smoke, but don't know for sure.

ETA - the Sdi injectors I fitted were brand new.

I bought a set of SDI injectors here for my 99bhp 45 and the performance boost is noticeable and no smoke.

i would just like to add, that when buying injectors, mileage etc can effect how they perform. You should get them ultrasonic cleaned before putting them in the car, as since i have started doing them, ive never had a bad running set yet. Used injectors can cause bad running.

also i have some dyno print outs of cars with only sdi's in, will try and find them.
