Thanks I’ll put my glasses on when I check this time! One of the team has ‘invested’ in a boroscope that works off a Android smart phone, we’ll check in the bores for domed pistons, just to confirm.

So it's a late factory reconditioned block with a late 2500 head.
Everything stacks up. I think you can dismiss any thoughts of it being a 2000!

johnnydog - Yes it’s a bonus for us. We are still going to use the boroscope to check how good the bores are and whether the head needs a decoke.

Good evening, I would like to ask your assistance in identifying an engine and cylinder head which is currently installed in my MGB GT. I know that this may appear to be heresy to some Triumph owners and I can understand why, because its also heresy to some MG owners too :( However, I am really pleased with my car, the engine and gearbox are much better than the standard 1800 4 pot unit and it makes the car much more like a proper British sports car should be.
So the engine number is MG57520E and the cylinder head is 218225. I was told when I bought the car last year that its from a Triumph 2500 PI? It has been totally rebuilt and sorted by TRGB and goes really well, its running twin SU HS6's with a custom exhaust and manifold so as you can imagine its a really nice drive. The main reason for wanting confirmation about the engines origin is so that when I need to purchase replacement parts I can obtain the correct ones first time. Its also running a Triumph O/D gearbox, which is a little noisy and will need attention before too long, I will find the serial number for identification purposes over the next day or so.

Any assistance you can provide will be much appreciated.

Regards. Mark

Hi Mark,
I can confirm that an engine no prefixed with MG is for a 132 bhp 2.5PI, and the 218225 head was fitted to both the 2000 and 2.5PI both from engine nos 50,000. The 2000 ran to engine no. approx ME 86,000 and the PI to approx. engine no MG 82,000 with this head.
If we can help you further in identifying the gearbox just post it on here!
