View Full Version : TR6 TR6 engine replacement options ?

I was wondering if anyone knows of a car engine
that might bolt onto an existing TR6 tranny.
Or one that might require just some minor
modifications to attach to the tranny. I do
know the engine mounts would be different.

I'm thinking maybe a small, reliable, V-6 that
I could pick up cheap at the auto graveyard.

Thanks, just thinking out loud. No, I have no interest
in going the V-8 route and all that a massive project like that entails.

regards,

Engine replacement Dale? :nonono: Well there's lots of V6 and V8 conversions out there but none are really a "drop-in" replacement that I know of. But here's a site devoted to just British V8 conversions:

My favorite may be this TR6 with a BMW M3 engine

WHY DALE?


:iagree:

And you'd be opening up a can of worms in terms of weight distribution, whether the bodywork will allow space for it to fit, the potential difficulties with cooling, routing the exhaust system, the effect of any power increases on the rest of the powertrain, possible difficulties in steering column placement, more braking needed to offset the more go, etc.

You've got to consider more than whether it'll just bolt in.

Quite a number of people have dropped V-8s into their Big Healeys to make "Nasty Boys" and the problems they've had to deal are likely to appear with any similar engine swap into a TR6.

I'm not a purist, but I'd think the problems and difficulties would reduce the appeal considerably....

<span style="color: #000099">Just thinking out loud is all.
I've got a nice looking, owner restored TR6,
that could give me great enjoyment if it did not
break down all the time. But it does. I think I've
taken the existing engine just about as far as possible--
way out here in the middle of the ocean.

I was thinking a V-6 engine from a small SUV might
work. And I could get it serviced anywhere on the
island. I cannot get my TR6 serviced anywhere except
by me. We've seen the disaster my attempts have brought!!!

Just pondering ways to get my TR6 to a state of
reliability so I can drive it up into the mountains.

Yes, but Joe is pretty handy with metal fabrication tools also. I wouldn't touch an engine transplant unless I met one of two conditions:

1. I was bloody rich and could pay someone to do it for me
2. I was someone that was skilled at metal fabrication. (or had a VERY good friend with the same skill)

Dale, I don't think your problems are mechanical in nature so I honestly think that an engine transplant would be a monumental waste of money. These TR engines are some of the simplest engines out there and for the most part are no more or less prone to failure than any other engine of the same era.

Plus, if you go with a more modern power plant, you'll be dealing with fuel injection.. and you think your ignition system is complicated? Just wait.

If you do feel this way, then I think you should consider a Miata or a Pontiac Solstice. I think you'd be much happier since it would never break down. But admitedly you would lose much of the character that draws people to these old cars in the first place. These troubles are things that every owner of a classic car deals with in one way or another, so you need to decide for yourself if this is the route you want to take. There will always be something that breaks or needs tweaking, thats just the way it is.

When did you purchace your car Dale?

I've had mine for 3 1/2 years now, it's just been recently that I've been able to actually enjoy it on the road. I still have issues with my TR6 but is'nt that half the fun of owning these little devils....

In terms of trouble shooting and problem resolution the farther away from stock you go the harder it will be to get help.

I believe you have an unresolved fueling issue, which has to be easier to fix than trying to swap in another engine....

For $400 you could have a new/rebuilt set of carbs with a STOCK linkage. Worst case sell your existing carbs and linkage and it will likely fund a "do-over".

Or, you could focus on your fishing until one of us can get down there to help you sort the issues....

Just under three years of breakdowns/repairs
with 1700 miles driven in total .

Everything in the engine compartment is either
brand new or has been rebuilt professionally.

I was thinking an engine swap was an easy thing.
SUV engines from wrecked cars are now a dime a dozen
with the cost of gas so high.

I was just pondering ways to get my car operational.
A shame to see it parked in the garage.

thanks all,

Dale - I think we are all deeply empathetic over how you must be feeling right now. I'm not as familiar with the car as you are obviously, but it seems like you have sorted the floors, engine bay, suspension, interior and just about everything else except for the fueling issue.

Sometimes it is good to just walk away for a month and then pick it back up.

Key thing is to only change one thing at a time or it becomes really hard to isolate problems.

Dale, my friend: What makes you think that a transplant would be any more reliable. If what you have told us and what I know about the business practices in PR, where would you find a reliable shop who would/could perform the surgery?

I believe that your best option is to keep your shoulder to the wheel and fix what you have. Perhaps you need to modify your strategy and address ONE system at a time, then move on the the next, and so forth. BTW, what is the status of Amos right now? The last I had read was something that looked like a rich fuel mixture.

Frank, I posted my response to your seat height question
in the Triumph forum as a "how to" maybe a week ago or so.

BTW- I WAS sorting out entire systems front to back. I had
multiple failures across systems and did not know it.

Ie- I replaced the entire fuel delivery system, a second time,
because I was not aware I had a failed dizzy condenser.
I had 75 miles or so on a new condenser when it failed. My bad.

I then also replaced almost all the ignition system not knowing
I had blown up the brand new condenser.

Right now? Clueless in Bayamon. Perhaps the car is operational?

I don't believe your problems are with the engine. They all have to do with things outside of the block. Dropping in a new block won't be the answer, it will only cause problems far beyond the teething problems you are currently experiencing.
Don't change horses mid stream.

Hi Dale
I gotta say for all the problems I read about on here your car seems to have a lot of them, Maybe we all need to pitch in, you provide the beds, beer and beef. we all fly down bring parts with us to go over all the electrical engine components plus carbs and we get this thing running again. Maybe in Jan when its cold up here

Hi Dale - I hope this doesn't come across as out of place but I think it is time for some step-by-step diagnosis.

One item at a time, well documented and examined, to nail down what is happening.

I bet it is one thing that can be isolated and then repaired.

Dale, the old expression is "The Devil is in the details". There is absolutely no doubt that you have gone through every major system on your car, some several times. Just to echo the sentiment already expressed by many others, there are one or two, maybe three or four, detail issues which have collaborated to frustrate you to wits end. To use another expression, perhaps you have lost sight of the forest for the trees, and who can blame you?

Truly, I'd hop a flight down there to help you if my knowledge of TR6's was stronger. It sounds like there are a couple of others who's expertise is excellent who will come. Final cliche here - :smile: - You have built it, let them come!

Nope Don-

T'was just a curiosity question. Nut and bolts I can do
and quite well. I've pulled the tranny myself and installed
new engine mounts myself. I have literally replaced almost every
fastener I could get a wrench onto.

I have no doubt at all that I could strip and remove the Beast's
engine and install a replacement IF the tranny to replacement engine fit.

I have zero $$$ for any fancy V-8 swaps. So, I am back to repair for
months; drive a coupla miles, breakdown, repair for months, drive a coupla miles, endless loop.

This thread can drift away now.

<span style="color: #006600">Oh yeah, I forgot to mention: very soon now the car
is due to have a serious, major breakdown that will again require
complete systems replacement over many months. How do I know this?

It stopped raining this morning, I fired up the beast and ran it's
wheels off for well over an hour at speeds up to 70 mph.

By tomorrow morning it should be dead again. ha, ha, ha!!

Over 25 years of reading about cars and trucks, I've learned that engine swaps are rarely ever cheap or reliable without a cubic dollar injection.

Typically, the effort required to do a swap is the same, regardless of whether it's a V6 or a V8, hence why most swaps are V8's.

The easiest/cheapest way will be to drop in an engne/trans combo and have the driveshaft modified to fit the new trans. Clutch and shifter issues are often why "cheap" swaps are usually automatics. The most reliable swap would be a EFI engine with the entire ECM harness from the doner car grafted in. If done DIY, this can be cheap: buy a wrecked, but still running car, and measure/fabricate as you go. (bear in mind, I know this only in theory from readin, I've never had time/space to attempt it).

fastccarsinc.com sells what is basically a bolt-in V8 swap for MGB, but the unit-body construction of that car lends itself to that. they have done a TR6 V8 as well, but don't describe how they did it.

I feel your pain... trying to keep one of these cars running can be painful... but I still don't think swapping out the engine will gain you much.

I'm pretty sure someone on here has a TR6 Supra project in progress. I remember seeing a video of it. I'd be interested to know how that is turning out.

As far as TRED's Pontiac powered TR6 goes, I think it's awesome and shows true skilled workmanship. If he were shooting for a concourse restoration, of which there are MANY, he failed miserably. If he was shooting for a mind-blowing muscle car in a sleek and unique body (one that would have otherwise ended up in a scrap heap) that he and his son can feel extremely proud about having accomplished together, I would say he succeeded, and way beyond excellent at that. I think he was going for the latter.

That's my vote anyway.

Dale, in all seriousness, all the joy/grief that you have gotten out of your car and you have yet to touch the one thing that will cause you the most grief/joy - the engine/tranny. Multiply times 2 that amount of joy, and money. I would think you could get a really, really nice used Miata for, say, 10 grand or even less. Heck, brand new ones are in just the low 20s. They are sweet little cars and very reliable. The same amount of joy as driving an LBC, without the breakdowns. Just being practical, bud. Shucks, I have considered the same for my beast, it is just that my wife would kill me.
