Nick Jackson (2) Posted August 19, 2013 Share Posted August 19, 2013 My GT6 has an MG serialled 2498cc engine and I'm trying to find out some more about it. So far I've found out the head is stamped 218225 and the casting number is 312388. According to the Triumph 2000 Register book there should also be a part number starting with a 5 somewhere but I can't find it. Does anyone know where to find the part number?If the engine numbers are broadly in line with the commission numbers my engine dates from late 1971.Any insight into the basic configuration or spec of this engine would be gratefully received. Being a former Picton car, the engine might have had a tweak or two, but I'll only know that if I take it apart. A bit drastic at this stage!ThanksNick Quote Link to comment Share on other sites More sharing options...
JimEB Posted August 19, 2013 Share Posted August 19, 2013 Have you looked at the tech stuff on Chris Witor's website? There's a PDF documenting cylinder head applications in his Technical section: http://www.chriswitor.com/technical.php Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted August 19, 2013 Share Posted August 19, 2013 Sounds like early Mk2 PI. Would have the "132" cam originally but who knows now!Nick Quote Link to comment Share on other sites More sharing options...
Nick Jackson (2) Posted August 19, 2013 Author Share Posted August 19, 2013 The Chris Witor info looks to be the same as the T2000 club info, which might be because CW is the common link? Quote Link to comment Share on other sites More sharing options...
nang Posted August 20, 2013 Share Posted August 20, 2013 I thought that the MG prefix was a P.I. motor but I've been known to be wrong before. :)Tony. Quote Link to comment Share on other sites More sharing options...
Richard B Posted August 20, 2013 Share Posted August 20, 2013 Yes MG is MkII PI.If original and pre 73 then yes should have the 132bhp cam and be a 2500. Although if in a GT6 it may have had 2000 components installed. If it has a GT6 sump then it is a 2000, if it has a deepened sump then could be a 2.5.Dave Picton has been known to put 2.5's in GT6's and Spitfires.

I have also been known to put 2.5s in GT6's and Spitfires as have many others.Laurence Quote Link to comment Share on other sites More sharing options...
DJB_Harvey Posted August 20, 2013 Share Posted August 20, 2013 IF that's the original head on that engine it's late PI 125 BHP ... Early PI motors had the head number 516816 .What's the complete engine number ? Quote Link to comment Share on other sites More sharing options...

Nick Jackson (2) Posted August 20, 2013 Author Share Posted August 20, 2013 It was owned by Robert Picton, his brother. They swapped the old 2000 unit for a PI 2500 engine. I e-mailed Dave Picton quite recently again but he hasn't replied as yet. If anyone has his ear perhaps they could offer him a gentle nudge by way of a reminder to reply? Thanks.
