My spitfire 1500 is knocking pretty good starting at 2500 rpm. Since the weather will be changing soon to colder I was entertaining the idea of doing a complete rebuild on the engine. Ive done a little research and have discovered there may be other options with other engines close to the same money. The car it self is pretty solid and I plan on keeping it for a long while. What should I do? Rebuild or upgrade to a different engine?

I personally wouldn't want a 1500 as an albatross around my neck. I have put number 3 rod thru the side of too many blocks. If you plan on keeping the car look for a small journal 1296. In the long run you will be a lot happier with it.

You could maybe just do a bearing job on it . That might get you up and running while you think about a full rebuild or another motor / trans .

If you have a nice car I would always opt for a rebuild/replace with a Triumph engine.

Just a once over as Lizzard suggests may be appropriate (and it is perfectly fine for most people), but if you want to drive hard, then a small crank 1300 is a better option, as it is quite happy at any RPM likely to be seen.

Thinking of the old "horseless carriage" idea you can think of it as having a nice carriage.

Now all you need is the horsepower.

Or torque.

Ever consider going EV?

As suggested, it depends how you see yourself using the car and what you want out of it.

Once in a while I think "what would I do if MY engine had a major issue." Put money into restoring it or another 1500, seek another SC engine, or bite the bullet and explore a modern engine/transmission transplant?

From what I have learned, NO transplant is without it's stubbling blocks, and the question still remains, ' will it still feel like a triumph?'

As a long time triumph owner, I am often astounded by what (these days, on this site) owners pay for machine shop services. For a large part this may be due to owners NOT assessing an engine themselves, but just dumping an oily engine or block on a pallet and asking for a quote 'fix it! ' I have been on the receving end of these myself (I do not have a machine shop but had access to one, and a good relationship with the machinists) My answer would be, " write me a blank check and trust me, or I will give you a quote with a 50% margin added"
Of course, many people do not like this, it requires some 'effort' if only dissision making, on their part. They would rather get a stupid quote, and bite the bullet and pay through the nose, assuming everything (when they get the engine back) will be huncky dory.

So back to the question. What are YOU prepared to do?

How long are you prepared to not drive the car?
Swapping in another running Spitfire motor can be done in as little as a few hours.
Adapting a different motor and/or drivetrain can take weeks, months, years, decades, forever ...

Forget about what you paid for the car, decide how much it would cost to buy your car if it was in good running condition.
A bargain is not what you pay, it's what you get.
