Hello, im looking to convert my 1275 engine into a low boost turbo motor using a clutch mounted gt17 turbo. The engine is in really good condition and is fitted with a kent 286 cam, the pistons are marked 21268 g7 l33. Can anyone please tell me what size dish these pistons have and also what is the standard compression of this engine? Also would a turbo oil pump be needed or is the standard pump up to the job? As I may run it n/a for a while before fitting the turbo. Second to last question... will the kent 286 cam Be any good? Its not a daily drive but more of a weekend toy so not to worried about drivability as long as it makes good power when I need it, last question!... is a centre main strao going to be really needed for my set up? The reason I ask is because I have booked a week off work which I intend to work solid on the mini to try and swap the gearbox.fit the engine and make the manifold so dont want many hold ups.

I know for a fact that the 286 is going to be useless, best off selling it, buying something like an mg metro or 266 and pocketing the difference mate. Standard oil pump has been proven to be more than up to the job but the high flow item won't hurt if you feel like fitting it. On 26th Jan, 2012 Tom Fenton said:

Ok brilliant thanks for the fast reply! Do you know if the 276 is any good as I have one laying round or again is that useless? What are your views on a centre main strap? |

A 276 is better than a 286, but still not quite as good as something tamer, by all means you could try it and if you're happy with the results it gives continue to use it. There's no downside to fitting a cms, I'd fit one to any non standard engine just for piece of mind for the little cost involved On 26th Jan, 2012 Tom Fenton said:

On a mildly tuned or low revving set up the centre strap is not needed. On 7th Oct, 2010 5haneJ said:

Ok thanks guys :) im at the stave where I need to start ording parts so dont want to miss anything :) I was planning to makw my own manifold but dontwant the turbo to sit silly close to th bulkhead, rather than completly remove that section of the bulkhead and box section has anyone just made the box section smaller to allow clearence for the gt17? Also I will be running a distributor.. will a standard metro turbo dizzy work with my set up or am I better locking a standard dizzy up to stop too much advance? I would like megajolt but for the time being money is tight. Thanks!

Can anyone please tell me what compression ratio the 21268 pistons give? Also if there a decent piston for a low boost engine, would be ideal if I was able to run low boost without touching the compression ratio |

Having done the 286 cam 20 years ago with turbo....do not even bother. It's horrific.
