Metro Turbo setup

[Matt]

Hi Guys

I have just aquired a complete metro turbo setup (inlet, exhaust, turbo, carb etc etc) and wondered exactly what is involved in fitting it!

My engine is a 1330 marina lump with a kent 276, whats peoples opinions of this cam on a turbo or would I be better off with an MG metro cam or and MG metro turbo cam?

I know I will need to knock up a downpipe (which will basically be a 90 degree bed with a flange on the end!), and my standard fuel pump won't be able to keep up so a facet pump and regulator will be required as well as an oil feed to the turbo

anything else I need to know about?

Simple.
Pop along to my house, lift the bonnet of the grey car on the driveway and keep working till there's no loose bits left.

There are four pipes connected to the fuel regulator: fuel in from pump, fuel out to carb, air from turbo, fuel return to tank.

It's so the turbo pressure regulates the fuel, and fitting a return fuel pipe to the tank was one reason for not using the turbo.

The 'Turbo' cam is a bog standard 1275 cam - MG did that for a good reason! The 276 will certainly be too wide on the timing (turbo will blow mixture through the inlet and out the exhausts on the overlap!) - I suppose you could try an MG cam - but really I would stick to standard. You will need to fit low compression pistons (ideally from a turbo engine) - and the bottom end will need to be in tip-top condition. Turbo head with sodium cooled exhaust vlaves should be used - and a higher pressure fuel supply will be needed.
Oh - and deep pockets to pay for the high fuel consumption!
Edit - you can maybe save some cash by simply machining (or careful filing!) some metal off the piston tops - you would need to do the maths - but up to 20 thou off the raised ring around the crown should be ok. Unless you go for proper forged pistons - I would limit any serious use of the turbo to short bursts of acceleration followed by steady speed cruising on light throttle.
