Car Forum / MINI / July 2004Standard 1275 -> 1275 Turbo
I am hoping to build a turbo motor for my Mini, and would I be right in thinking that the modifications to a standard 1275 would be a turbo head, turbo pistons and a different camshaft? I already have a complete set of Metro turbo components, I.E. manifolds, carb, actuator, various plumbing, etc. Many Thanks Sean Hamerton Don't forget to make sure you can stop it too ! Good luck and enjoy it when it's done Stu > I am hoping to build a turbo motor for my Mini, and would I be right in > thinking that the modifications to a standard 1275 would be a turbo head, [quoted text clipped - 6 lines] > > Sean Hamerton I'm looking at some ferodo brake discs and pads as I type this... > Don't forget to make sure you can stop it too ! > [quoted text clipped - 12 lines] > > > > Sean Hamerton "Sean Hamerton" <sean.hamerton@ntlworld.com> wrote in news:FUgEc.2633 $Cs1.954@newsfe6-win: > I am hoping to build a turbo motor for my Mini, and would I be right in > thinking that the modifications to a standard 1275 would be a turbo head, > turbo pistons and a different camshaft? I think the head has sodium cooled valves that are slightly bigger than standard - but that might be the only difference. You'll also want a turbo head gasket, which are a bit more pricey. And I think you need to cut and patch up the bulkhead to fit the turbo & manifold. Some info on: http://www.ime.org.uk/ime/t/turbo_conversion.html I knew about the gasket and the box section needed in the firewall, thanks. Specifically the engine modifications required were my main concern. I suspect I'll try and source a metro gearbox too. Was the Metro Turbo 'box 5 speed by any chance? > "Sean Hamerton" <sean.hamerton@ntlworld.com> wrote in news:FUgEc.2633 > $Cs1.954@newsfe6-win: [quoted text clipped - 12 lines] > > Some info on: http://www.ime.org.uk/ime/t/turbo_conversion.html NO the trurbo was 4 speed :( If you want a 5 speed you will have to pay ???? for it How about a later metro 'box? A chum of mine had a '90 metro and that had a 5 speed. Would that bolt straight on? > NO the trurbo was 4 speed :( > > If you want a 5 speed you will have to pay ???? for it > How about a later metro 'box? > > A chum of mine had a '90 metro and that had a 5 speed.

The only way is the EXPENSIVE aftermarket boxes from Jack Knight or MiniSport. The problem with those are that the 5th gear is actually 1:1, with all the other gears shorter, so there really isn't much benefit for everyday usage. Just stick with a good 4 speed minis dont need 5 speed boxes > I am hoping to build a turbo motor for my Mini, and would I be right in > thinking that the modifications to a standard 1275 would be a turbo head, [quoted text clipped - 6 lines] > > Sean Hamerton Only fair to warn you, I knew two people who bought young Metro Turbos, and both hated them. Not nearly as quick as they expected, irritating noises. Big disappointment. One guy went back to a 1380 mini, which he reckoned was more drivable and more fun, the other got a Golf GTi Get the brakes, forget the engine, was the verdict. Lock I think that the crank is different too, stronger on turbos. The distributor also has a different advance curve. You will also need the turbo fuel pump and the piping from the fuel tank needs modding. Try to get hold of a Haynes Metro manual, shows the fuel system in there. I recommend you find an old turbo unit and rebuild it You dont need to use the Metro ECU. I had a Metro Turbo that had been modded by Swiftune, approx 125bhp, went like hell, loads of torque makes it easy to drive, no small power band as normal with high output A Series.
