My latest project: Triumph XR4x4i

Chevy LS V8's on the right. They are mostly dressed, have fuel rails and bits on them. No alternator, but they usually sit under one of the cylinder banks, so don't make it any bigger really.

The other engine is a Nissan V6 QV35, thinks its what is in the 350z or similar.


This isn't to say all V6's are big, they simply aren't. Just an example.

However DOHC generally makes a Vee engine wider and taller as you've got 4 cams to fit in. And you need something to drive them (usually a belt, but might be a chain), so usually adds length too.

The LS engines are OHV, so a single cam in the block, this keeps the heads small and the height low. It also uses a very short simple chain from crank to cam, so adds no real length to it either.


The Rover KV6 is a nice compact modern style V6:


But it's only 2.5 litres, so limited n/a tuning unless you are building a high revving race engine.

Fair enough. I thing someone fitted a cologne cosworth V6 into a dolly so in theory, a jag V6 should fit as they are fairly similar? I think

KV6 is a good engine but I can't be bothered doing all the bell housing work to make it RWD, jag one is already RWD. A wankel might be good as the torque is low and there plenty of tuners out there, plus 9k redline

I don't think the Jag AJV6 (or the Ford variant) share anything with the old Cologne V6.

If you really fancy a Cologne, then I'd say try and find a late SOHC 4.0 variant. Used in the S197 Mustang and in US spec base model LR3's (Disco 3's instead of the diesel used elsewhere).

The Mustang version made 210hp and LR3's 216hp, both with a lot more torque than the 24v Cosworth 2.9 version. And obviously smaller being SOHC rather than DOHC.


The Mustangs version also runs a very lazy state of tune as the crappy Ford modular 4.6 motor at the time only made 260hp in 2v PI form and 300hp in 3v form. The 4.0 litre six had to be made a bit lame to distance the performance from the V8 models.

300hp with a few mods on a 4.0 litre Cologne really isn't that hard. And they take to boost quite well too.

With some luck you might find one in the UK from a written off S197 Mustang.


I'd avoid the older OHV variant found in things like the Explorer. They probably have potential, but start with only 160hp, so will require far more work to bring the power up.

I'll see if I can find one, a 4.0 sounds like a rather large engine but being a 'murican engine, it wouldn't surprise me that it reacts well to a tune. Getting a LD3 would be great as they would be cheap and easy to find

Maybe I wasn't clear enough

The Cologne 4.0 SOHC V6 is still a Cologne engine, think it was even built in Germany, however was used mostly for the N. American market.

Physically it's the same size on the outside as all other Cologne V6's. It's American because ALL Fords are American when you come down to it. But that means little about it's tuning potential.

Sorry, I didn't realise that it was the the same engine, sounds like a good idea tho

Right, got a plan sorted and nailed down

I'm going to be using a jag 3.0 V6 with a manual, just bought a full car as it was cheaper to get it all as one.

LSD is going to be done later but for now, it's engine removal and fitment

Good choice i think! Nice an easy initial conversion, and with a complete donor you have all the bits you should need!

Should be, next task is to try and sort out how I'll be fitting it and the method of putting it in as there's barely any room in my garage to do it

Fun (!)

Got a manual jag s type bought for parts and it's now sat outside, awaiting it's fate

Some interesting choice of engines suggested here. The Rover/TVR V8 is a logical option, same with 250bhp being the sensible and usable power...but I like the idea of a 4WD TC with a grunty engine that could turn this humble Triumph into a triumphant Triumph...therefore, why not a Subaru 2.5l from an FXT complete with all running gear? 223bhp as standard, highly highly tunable, all with lightweight modernity and compact footprint, all parts readily available from a multitude of good proven suppliers, an immense support group c/o the many highly knowledgeable forums...and absolute unbustable mechanicals. It's bit of a no-brainer really.

I have a turbo forester about to go for scrap...

I know someone who measured up for Impreza running gear but there isn't enough room between the two inner wings for the engine - one of the things small Triumphs were famous for was their impressive turning circle, so the wheelarches intrude a long way.

I looked up Subaru engine dimensions long ago for another dream build and the engine is too wide to sit over the front axle. It might fit right at the front and if have to mount the radiator behind the engine over the gearbox.

I've discussed it on the triumph forums and it's probably easier to take an AWD car and put triumph shell on top, another idea was making a space frame sytle racer similar to the zakspeed Capri and making it use day R32GTR running gear
