Thread: Engine Swap - TD5 90 to .......LS1/6......?

Maybe you could just bolt the output flange directly to the rear diff.

You would just need some flexible gearbox mounts.

well if 5 litres is to be the maximum...

What about the 3rd one down on here...?!

Equicar 4x4 - land rover parts, land rover discovery parts, range rover parts, second hand car parts, freelander parts, cherokee parts, shogun parts.

Just a thought.Why dont you turbo charge a 3.9? I have done it to my 3.9(Standard)Rover SD1 on straight gas and it made 156kw at the wheels.Only runs 5 psi and still gets over 400 km out of a tank.Has heaps of torque and made all its power by 4800 rpm.In the long run you wouldnt have to do no where near as much work.

Put a 5 litre LR TVR V8 in it.
Check out the Triumph mob in SA ( sorry cannot advertise).

The cost of a Wildcat V8 would be cheaper than sticking a heavy GM iron motor in, plus you don't need to change bell housing, mountings, etc. It will all BOLT in.

The vehicle was designed and built to house certain engines.
It is a bit like the "enlightened" who stick GM motors into Jaguars and then wonder why the driving "balance" has gone.

Stick to the real thing and you will have a fantastic engine!
Those two english guys are onto a good thing.

hey pete, after speaking to several engineers i got answers from 4L up to 5L, with 5L coming from my mechanics engineer.


if you supercharge/turbo it obviously it is lower, my mate can't get his 4.6L defender engineered with a blower. not sure how small you have to go before thats allowed, i will be finding out though.

find out what JE engineering and twisted performance do to their TD5's to get the big figures they pull....from memory...

still hasn't got that rumble though

I'd be guessing that the GM motors these guys are talking about i.e the Gen111 are probably no heavier than a rover v8 as they ARE all alloy.

Sam,

Thanks for the reply. I will have a chat to 'my' engineer tommorow and see what his opinions are.

TD5 tuning seems to be pretty easy, but say 250bhp versus 450bhp is still a big difference! I also cant fit a larger intercooler as my high mount is so far back into the grill.

Vern,

Yep spot on they are all alloy, so weight shouldnt be an issue.

Ron,

As Vern says they are alloy so weight isnt an issue. Just to add the rover V8 wont bolt onto the TD5 box without some mods. (input shaft and bell housing at least)

Chris,

Its an option but the GM engines are going to be a better option if I can be allowed to fit one. Bearing in mind they are a lot bigger, and very simple, with huge tuning potential..... 600bhp+ more with forced induction, it should give you a very reliable, long lasting engine.

The thing against putting a Rover V8 in for me is that they arent that powerful, and for the amount of work to change the engine, and everything associated Iwith it I just couldnt face it without a big increase. I suppose a 5l Rover would be ok, but very very expensive, and still a hundred BHP down on a standard LS*

I would rather try and build a 'race' td5. The trouble with this is that it gets to be a short 'life' between rebuilds, which is something you wouldnt suffer from with a large capacity v8. The other thing with building very powerful modern diesels is the stupidly high injection pressures which make altering things much harder.... I mean 20000psi.. as opposed to say 70psi for a petrol!

Havent got anything against turbos or forced induction either as I have built a number of very powerul small capacity engines running forced and NA induction.... 267bhp at 10k rpm for example for a NA 4cyl 2 litre and 391bhp at 7400rpm from a longish stroke 4cyl 2 litre turbo reliabley.

Will post a thread update tomorow with the engineers comments (seems ridiculous to me I am an engineer!)

Cheers
Pete
