Newbie looking for advice
Turbo Mini Forums

Hello all had my mini for around 4 years now just fully rebuilt a 1275 to a 1312 but now it's all together in debating to turbo or not??
Currently my compression is to high 10:5 so this is my spec
Bored to 1312
266 cam
1.5 rockers
29/35 Inlet and exhaust valves
9.75cr pistions
I have been orffered a turbo head,turbo,montego plenium and diff
Is it worth me stripping the engine and fitting these parts?? What will I have to go besides change my head? Can I reuse the valves? What other parts will I need? Much extra power will I get? 100bhp?where as now I got 75? Many thanks

hello and welcome ,the search button next to log out will be a great place to start reading and will give you all the answers you will need.

for me having just finished one build i would be using that one first then decide collecting bits and researching

i've been registered a while now and i've not got round to anything yet apart from collecting and researching there are a lot of very knowledgeable folk on here who will help and advise but most topics that you likely need have been covered already and they are easily at your disposal.

welcome again

Outside the box

The Turbo head is basically no different to any other 940 casting. The difference lies in the sodium filled exhaust valves. Most people just bin these anyway and run the stainless race valves which are superior.
The turbo head runs 33mm inlet valves as standard, in which case your 35.6mm inlets won't fit unless you have the head modified to suit.

Can you provide a detailed list of what I will need? Or what I could use off my engine as it stands it hasn't even been run yet so everything's new
Might keep my engine as is for now and enjoy it and collect parts as time goes just unsure of the parts I will need to make the conversion many thanks

Welcome to TM

have a look around at some of the previous threads as this has all been covered before.

You can find the archive here of the turbo-mini website with lots of useful info to read.

Why did they run sodium filled exhaust valves?

to cool the exhaust valve, i gues the sodium must be very thermaly conductive.

The valve is a hollow stem filled with sodium, which melts at around 100c.
