TD5 Conversion HELP!!

[Devon-Rover]

Here explains it well

[Tinks]

Cheers mate! :D

Wow it sounds pretty good.  Is it as good as it sounds?

That link showed the comparison between the 300TDI & the 2.8 but how does it compare to a TD5? :?

[unknownmanxman]

TD5 has 122BHP@4200 and 221lbft@1950

Also check out: http://www.mdengineering.co.uk/

So the 2.8 has better specs... but it puts you up into the next road tax category!

[Tinks]

Ah man i did'nt now my road tax could get any worse!!!

It's gotta be worth it tho, think of the fun!!! :lol:

I'm definatly gonna have to look into this idea more, it sounds very tempting!!! :D

Anybody got one of these then?? :?

[Muddy]

Does anyone have any info on the 2.8 iveco unit in the santana? i think that put outs a fair bit of torque and sounds ripe for tweaking. Anyone know of any conversions?

[Porny]

Hrmmm... the TGV....

All over very quick (small power band), doesn't rev that well and you will quickley go through gearboxes....

Not actually a bad engine, but better for 'slogging' than being driven like you stole it   ...
Cheaper to buy from http://www.prinsmaasdijk.nl/landroverengine/index.html than anywhere in the UK... they are very helpful and speak good english.

Really depends what your after.

And with ones of these fitted it will NOT affect your road tax.... and older car over 1549cc pays the same price!!

think that i'd rather do things thw correct way. I definatly prefer to know that once i've built it any parts i should need to replace in the likley event that i break something, i will be able to get off the shelf.  

I like the sound of leaving my fuel tank were it is, will that create any problems if i was to use a new chassis?  It should'nt be too difficult to make new mounts should it as i'm keen on keeping my chassis cos its in good nik and i don't have alot of dosh to chuck at it!  

I dont really want start messin with my exhaust down pipe cos its a nice ss one  

I also like the sound of it being a fact that everything will fit, so Defender engine it is!!  

Oh and i also meant to say thanks very much for all the help your giving me  

Moving the fuel tank doesn't really effect anything.... apart from a underseat tank has a smaller capacity... and will probably have to run an aftermarket pump (although there is a way around this)

Your exhaust will have to be changed - the bore on a 200tdi is too small for a Td5 - so you will restrict performance (the front bit won't fit a TGV either).

Does it depend which version you go for as to whether you go through gearboxes? The variable turbo version has a max torque of 375 Nm, which is pretty close to the max torque of the 200tdi gearbox i think.
But the wastegate version has a max torque of 355Nm.

[Tinks]

"Drive it like you stole it" thats definatly more me! :lol:

Want to build something not too sensible but still practical, if you see what i mean? :?

Never had any trouble with my fue tank being the size it is so i don't think i'm bothered about that!  Sounds like it would be easier to leave it were it is anyway?

Oooh don't want to restrict performance i'm not that attached to the exhaust pipe! :lol:

If you go for the none VNT version.... why bother??  Just fit a tweaked 300Tdi....

An R380  (Which it should really be mounted too) should, as it's name suggests, take 380Nm... however I think it probably the way the power is delivered that kills the gearboxes (and shortens the life of standard clutches).  Ashcrofts can build you an R380 that will take it (bases on TVR internals AFAIK) but it isn't cheap.

If you leave it where it is then you will have to play around with fuel pumps... but at least you can keep your existing rear tub.

That's if your planning on keeping your existing chassis.... if you go for a new Td5 one I'd fit the Td5 tank.

Then you've just got the choice of fitting the R380 gearbox and the Td5 in the standard factory position, or mounting the gearbox on the LT77 mounts - so keeping your seatbox, floors and props - or fitting a 300Tdi spec seat box and floor, and then either Td5 or 300Tdi Props.... and thus putting the engine in the correct postion.


In all honesty the conversion isn't as easy as say a 300Tdi.. but still very do-able.

Just been looking at your 90 doin the twist off & kicking some ass in the modified vehicle section :D  Looks awesome 8)

Right i'm gonna make an executive decision & i'm gona stick to it, i've always wanted a TD5 so i'm gona get one!!   8)

TD5 it is!  Just need to to get one and start building, will probably need lots of help!

F.A.O Porney...

Whats the way around having to use a td5 under the rear tub you refer to earlier in the post?
And how do the td5's hold up offroad as far as electrics & water. and driveability with that fly by wire throttle? Im not a sceptic of the td5 offroad.. im just interested as ive never driven one offroad!

Where's the extra 'e' from....  

Whats the way around having to use a td5 under the rear tub you refer to earlier in the post?

Two ways....

Either use a single facet pump as Devon do (AFAIK) - 'I think' they also get rid of the fuel filter - and just run a smaller one instead (not the best method as the proper filter 'filters' down to 3 mircron - to protect the EUI injectors) - but will work without a problem...

Or run a Facet or similar pump and keep the original filter in situ.. which will work, but will not allow the filter to operate correctly (you could actually run two pumps....)

The other method...

I can get a custom aluminium tank made that sits in the standard underseat position - but has the correct apperture to fit the Td5 in tank pump... this means you can keep the standard Td5 filter and pump - and the fuel gets correctly filted and thus prolongs the life of the injector.


A td5 fuel pump is quite special as it offers a two stage pressure...  the fuel is actually filtered twice before it goes through the engine - and works at two different pressures.

Have a read here for more info (as feeling lazy!!): http://www.discoveryownersclub.org/tech/td5engine/

Thats a good question.. where did that extra 'e' come from! lol

That bit wasn't there when I replied earlier  :shock:  :?

No problems... and if you look where people like Simon from Devon 4x4 takes his then 'normal   ' people shouldn't have a problem.

The only weak point can be the sealing of the ECU... though this is easily sorted either by re-routing the addtional wiring or via a relocation kit from Dastek (though I might make a couple up soon as I want one!!!) - and thus putting the ECU out of harms way.

Throttle wise... even being submerged doesn't seem to affect things!!!

A Td5 changes the throttle response when you select low range - which works well.... and I for one like the way they drive (both on and off road)

Porny,

I'm told that should i put a TD5 disco engine into my truck that there is an alarm on the ECU that would have to be diabled before i could start it and that you would be able to do this?? :?

If so what sorta price :?

Cheers, Maria

Why have you been told that then???  :?

You would need to use the Defender Alarm unit - which is easy to set up  


Ian

[Tinks]

I get told alot of things! Everyone knows something. :lol:

So when i plumb in the engine it should start straight up ? :?

Do i have to have an alarm? :?

I've no idea why someone would suggest using a Discovery engine and box... perhaps it's because a Disco is slightly more powerful as standard, but irrevent when it's remapped!!

The other problem would be using a Disco spec ECU - if you tried to connect it to a Defender Td5 dashboard you'd find your temp gauge working the wrong way round (not just a case of swapping wires either!!)

Personnally I'd go for a Defender spec engine (a Disco engine is virtually the same though) and a Defender spec gearbox  - that way everything fits and parts are off the shelf - and it looks properly done, not someones bodge attempt.


To get the engine to run the ECU needs to be coded to the alarm ECU (10AS unit) - a Td5 will not run without a 10AS unit, but the 10AS unit can be put into it's most state so won't actually do anything (not even act as an immobilser) - but it still needs to send a signal back to the ECU.

Ideally you need to have the injector codes in the ECU - but a Td5 will run with the wrong codes, but isn't ideal.  

The ECU also needs to be the correct level for the engine - i.e. EU2 or EU3.


As long as the ECU is matched to the engine, and coded to the 10As unit the engine will start.


Ian

[Tinks]

I think mostly because there easier to come by and a bit cheaper.

I know that it'll make things a bit harder in terms of wiring but it is quite possible right? :?

If i'm connecting the TD5 dico ECU to a TDI dash board what will happen, will it work at all or just work all the wrong way round?? :?
