mk2 vitesse engine swop
Discussion
It will fit but will require some modifications.
It's been a while since I've read about this but you MAY have to fit the sump off of the 2L, 'massaging' it with a hammer to add some dents for the longer throw crank to rotate without hitting at the non-bowl end.
One thing you WILL need to swap if memory serves is the front end plate. The engine sits at an angle in the big saloons but vertical in the Vitesse. I believe the end plates are a straight swap and move the mounting points back to the correct locations. You will obviously have to swap to the Vitesse gearbox at this point to get the gearstick back in the right place.
Your best bet is probably posting on one of the more modification-inclined Triumph forums, either Club Triumph or probably better the Sideways forums (http://www.sideways-technologies.co.uk/).

It's virtually a straight swap.
Sump will need changing and modifying as mentioned. Best to swap front engine plates over (looks a lot tidier) - Vitesse mounting blocks bolt on as the cylinder blocks are the same.
Use the Vitesse backplate, flywheel etc for an easy life. 2.5 J type overdive boxes are possible to fit with some messing about.
Start saving for a new differential, the crownwheel carriers are prone to fatigue - even more so with the torque of a 2.5.
Be gentle with the gearbox - a D type overdrive was never meant for a 2.5 engine.

I had a Vitesse Saloon a few years back with the 2.5 engine, inch and three quarter SU's and an extractor manifold, stainless system with twin pipes coming out of each rear corner. It was RAPID!! I loved that car....sadly my boiler at home packed up and as we had spent a fortune already on the house I sold the Vitesse to fund it rather that clearing the savings out! What a stupid mistake that was!! Wish I still had it now, here she is.....
Ive got a Mk1 with fairly tuned 2.6 in it - you are gonna love it, just hammer the sump to fit!
A 2.5 makes the car very quick but what gearbox are you planning to use
I have just swapped from J Type with dolomite 1850 internals to a 2.5 saloon box as the torque of the 2.5 kept pulling the J apart.
We had to cut and box the chassis as it's a bigger box but fingers crossed it will last longer.
