were is the best place to get a metro turbo engine from
Turbo Mini Forums

help

Welcome to TM.

Best thing is to build your own. No difference to a normal engine really. And just buy all the turbo gubbins to go with it.

Also if you ever need anything on this forum remember to have a search for it first. Most likely the question has already been asked and answered.

Hello and welcome to Turbominis.
I've done quite a few mini turbo conversions over the past 10 years or so, so if you get stuck give me a shout. As already has been said you will need to cut your bulkhead, unless you use a mirage manifold set, but these are around £350. What do you plan to use the car for, as since the metro turbo came out, things have moved on quite a bit. The t3 turbo fitted to the metro is very old by todays standards, I'd recomened fitting the t2 from a renault 5, or maybe something newer from the GT range of turbo's from garrett.

You don't need to replace your fuel tank, you can have the return go back in the the fuel line with a 't' peice, although often easier to fit and spi or mpi tank.

Don't forget that most metro turbo engine are over 20years old now so will need a full rebuild, the metro turbo rings are NLA so you will need to go +020 rebore. So it's not really that important to get one as a donner engine.

There are lots of myths around about turbo blocks and cranks being different. All the turbo blocks are the same as 90% of a+ (non mpi) blocks, and the cranks fitted to most of the turbo's was the cam6232, which is again a std 1275 crank. There was a cam6521 fitted to some of the earlier turbo engines, but this is not really needed.

The gearbox is also the same, apart from a different final drive, and a larger bearing on the input gear (different transfer housing) then they are exactly the same as any 998 a+ box, and when you see the price of the turbo nose bearing, you'll soon wish you had a std transfer housing.

The metro turbo head came with sodium cooled valves, there is also a myth that these are needed. I have not run them in years and never will, the valve heads have a habbet of falling off. I'd use stainless valves, nice and cheap, and reliable.

If you want to turbo a std engine, you'll need to drop the compression ratio, this all depends on what boost you plan to run. The best way of doing this is to have a large dish in the pistons, if you need some more CC's, THEN started taking material from the head.

The metro turbo cam is a std 1275 cam, it's very mild, the Dizzy is different and so is the carb.

The metro turbo also had a different inlet and exhaust manifold.

So to convert a std 1275 engine to turbo you will need.

Metro turbo dizzy (or go mapped ignition/mega jolt)
Metro turbo carb (or can convert normal 1 3/4 su to boost sensative)
High pressure fuel pump (spi, mpi or metro turbo)
riasing rate fuel pressure regulator from metro turbo
low compression pistons.
bulkhead box (or go for different manifold
metro turbo exhaust manifold
turbo charger (I strongly recomended avoiding the metro item)
plenum chamber
inlet manifold
I'd recomend the mg metro cam, (not turbo) or avonbar phase2 cam.

Any more questionlet me know.
