Vitesse Engine suffix

[Robin]

Does anyone know the difference between an HE and HL suffix on a Vitesse mk 2 engine block?

HE is the suffix for a High Compression Engine.

 

As far as I know, HL is not a valid Triumph suffix, and is probably a stamping error, with a badly stamped E.

[GFL]

Agree with Kevin

 

A MK2 Vitesse Engine should be between HC50001HE up to around HC58200HE for the engine number for a Uk Car?

 

I think the abreviation LE was used at the end for Low Compression (Used for certain Export countries)

Thanks for all the responses

Could just jump in to this topic, Ive had my MK 1 Vitesse a few months now and when i brought it the owner stated the car had a Triumph 2.5 straight 6.  Ive looked at the engine and it does have 2 x SU6's, gearbox has overdrive but the engine numbers are MG3970HEBW!
 
Could anyone shed some light please? It all runs perfect and sounds awesome but i would like to get a new rocker cover etc but not sure what engine it is ;-)
 
It also has a blocked off hole/vent/sender mount near the rear by the bulk head just below the rocker cover(cant seem to load up pics)
 
Your help is great appreciated
 
Regards

Rich - I think it's from a 2500 pi mk2 but worth checking one of the online databases

MkII 2.5 Pi Saloon, Estate

That accounts for most of it, up to the HE.  can't help with the BW, unless it was originally mated to a Borg Warner overdrive

Many thanks Robin and Casper, so for spares I should just go down the 2500 route? Was the 2500pi the injection engine? I suppose it was and they done away with the injection and put on the SU HS 6 carbs?

 

It has got over drive makes me think that it may have all the running gear

 

Once again thanks for your help

I very much doubt it has the saloon type gearbox. Check the reverse position, it will tell you which box is fitted (I can't remember at the moment, but that is the easiest way to tell)

 

The vast majority of parts will be the same as a mk2 vitesse, including rocker cover which are the same on all 6 pot cars. Clutch, oilfilters should be vitesse or possibly a spin on? Air filters may be problematical, many people use K+N or similar.

Blanked off port, guessing it may have a square head? some cars have them as a blank for a waterway. Used on some cars, not others. Not an issue.

MG is engine prefix for 2500PI MK2 saloon and estate

 

BW is Borg Warner automatic  which would have denoted the spigot brg and drive plate requirement  (obviously now removed )

 

all big saloon gearboxes have reverse to the right and back 

 

if your reverse is forwards you have the original 3 rail or similar ,  which needs care behind 2.5 ltr.

 

 

as for clutch it was used across the whole  range   eg  http://www.rimmerbros.co.uk/Item--i-GCC228P

Thank you all for your help and advice. The reverse is left and up so i'd better take care of the box, at least it has overdrive which helps considerably.

 

all the best

[Pete Lewis]

that  would  be a std 3 rail box  , 

   the type number is stamped on the top case face alongside the top cover

Many thanks for all your help and advice

 

I'll get to the gearbox and diff to find out who here numbers
