For that price, why the hell not?

If you can tune them yourself, should be good. You can always swap back right?

Don't do it, those carbs are garbage!! My father has owned 3 range rovers and a rover car or two and by switching from the strombergs to the british SU's found on the earlier rovers (pre pollution) he gained power, and got better fuel ecconomy. This has been on two different engines, in two different cars. Currently, they are on a 4.4L leyland engine in his Rangie, and that thing can drag off little buzz boxes at the lights quite easily. They probably won't help you car much, if at all.

Also, the earlier SU's are the same ones used on Toranas and such.

Hey Speedy, what do you mean by "Toranas and such"? The only Toranas I know of that used side draught carbies were the little Brabham Torana 4cyl. using a single Stromberg Zenith CD 150, the LC 186cu.in. XU-1 using three Stromberg CD 150's and the L J XU-1 202cu.in. that got three 175 CD Zenith Strombergs . Did you mean SU type carbies? The only side draught carb I've seen on a V8 Rover (1974 RangeRover) was the 2x 175 CD Zenith Strombergs . Did earlier ones (Rover V8's?,P6B 3500S?) get real SU's? I've always liked them, but never had a close look:stupid:

I'd have to agree about their performance on the Rangies, but that may have been a case of poor choice by BL. Constant Depression diaphram carbies on a 2.5 tonne 3.5 litre 4x4!? They did much better on the smaller and lighter(~1100kgs) XU-1's...but even there, for flat out performance you were better off switching to 3x 2" SU's. What's a Z weigh?

Two properly reco'ed (ie correctly needle and jetted)175 side draughts on a warm 2.8L Z just might work. I guess it all comes down to cost. What size are the current carbies?

If it's of any help, the "175" equated to 1.75 inches or ~44mm, "150" =1.5inches or ~38mm.

my z has always been a bit of a get together project with a mate,so if the strombergs dont work well ill fit the fuel injection to it,,dunno,, early good SUs are had to get,, i dont have anymoney to play with

Sorry, I'm a little vauge on exact details because my father waffles on lots and I tune out a fair bit. On the Rover SDI cars, the 79 model had a high compression motor with twin SU's. 2 inch I think. They look like the Z ones, but are bigger and heavier. Then in the 80's, the compression was dropped and the carbs were changed to the strombergs. You can pick up a set of the SU's with manifold (for the rover engine) to 'suit rebuild' for $250. The Rangie was never a performance car, so I guess it never got the good carbs.

My father was talking to one of his mates about them and they were comparing them to some Aussie muscle car and realised they were the same carbs. Not sure which car, but pretty sure it was holden. Might have been a factory backed race thing though because his friend was a mechanic for a bathurst team many years ago.

I know what you mean, that is standard operational procedure for my son unless we're talking music:classic:

They sound like blokes of my era. Definitely the 1972-3 Holden Torana LJ XU-1. The 175CD's were standard on this model. The factory (dealer team) ran a variety of setups.If I remember correctly, The 1973 "Bathurst 500" entered cars...one ran triple SU's not CD's, and the other ran triple 58mm dcoe webers with one choke blanked off!! This was so it still complied with the original 3 choke setup of the showroom cars. Doug Chivas had the SU equipped car, remember him having to push it, out of fuel, in pit lane?

I've included a pic of the Bob Morris driven, Ron Hodgson owned series production XU-1 with the Weber setup I spoke of....one way to interpret rules I guess! This pic was taken years ago (early eighties?) in the Mt Panorama Motorsport museum. By then the car was in private hands.
