300 tdi into 101 lift pump question

That is going to be VERY underpowered mate. Hope it's not!

Suggest you check your figures before criticising

Critical? Nige? Nah, opinionated maybe and generally intolerant of fools but I see no criticism in the above.

Sorry mate, I wasn't criticising, it's a diesel & figures don't really mean a great deal when it comes to driving the car. It is slow enough in a Disco, it is going to be very slow in a 101 i think. The power delivery of a diesel & the gear ratios in a 101 will be a poor match in my view. Are you changing the gearbox?

The jump from second to third is so big it could cause 'driveablility' issues.

I'm sure someone who knows more than me will come along soon enough

Many 101s have 200Tdi engines, some have 300Tdis, some even apparently have factory fitted 300s in a last ditch effort to get a refurb contract from the MOD. Its a good match. Even a straight 200 will give slightly more output than the early 3.5 V8 in a 101, and tweaked you can be in the 160 Hp+ region, and lots of torque region without much difficulty - decent intercooler, pump tweak territory. Propane enrichment can boost that again.

Zeus even make/made a conversion bell housing...

I am transplanting the engine with gearbox.

I have 20 years experience in 101's and I think there is only one conversion that I haven't driven and that's the iveco daily engine. I have driven 101 GS's and Ambulances with the TDi engine in. Yes the engine needs to be worked but goes ok. Not as good as say a Perkins 1004 or Mazda 3.5 turbo intercooled or GM V8 diesel if you want to tow but it depends what your looking for and the work your prepared to do in altering axle ratios.

Its all a matter of balancing the pros and cons.

Fair enough, my main concern was the power delivery from a diesel is totally different than a V8 petrol.

Fair enough, i was only thinking of the possible power delivery problems, I'm not a rivet counter!!!

That depends on how you tune it. might have fun finding a good place for the intercooler, and it'd benefit from a bigger intercooler, too, which would allow it to run more boost, but even with a standard intercooler you can get 'em to go reasonably well - ditching the cat from the 'zorst will help too.

Output figures for the pre-79 rangie, which is more or less the same engine as the 101 I think, are 130 BHP and 185 lb-ft, so the TDi in standard tune is down a bit on power and up a bit on torque. The maximum revs are lower, but the TDi pulls well at 2500-3000 revs which is a comfortable level for the V8 as well.

Upping the intercooler size and winding up both boost and fuelling a bit on the pump will probably, without spending big money, get the 300 to outperform the V8. Might need to up the high-range t-box gears a bit, depending on how it's geared to start with.

Nick, I am about to put a 200 into mine. Have you moved the engine mounts ?

How are you handling the gear change ?

and the work your prepared to do in altering axle ratios.

Are you doing any transmission changes ?

Steve

Steve,

Yes cut off engine and gearbox mounts and made up new ones. (note there are different tdi 200/300 engine and gearbox mounts and different length bellhousings) main gearbox change- made up new link in inch box section High low used Bowden cable dif lock used vacuum actuator off lt95 gearbox (can use wiper motor though) no need to alter axle ratios and better not to so it keeps good off road ability transfer box is 1.222 as vehicle is going on expedition but it would be possible to change to 1.003 for motorway etc use

Back to my original question- it looks as if they are M12x1.0

Does anyone know where to get hose tails for M6 pipe with this thread and an olive union?

It would be easy mounting an IC on a 101... loads of space infront of the radiator! You might have to be creative with your pipework or possibly get a custom radiator so you could get the pipes past it though.

So I can´t beg the dimensions of where the mounts go. Damn. So offer the whole engine/gearbox up and work out what fits where ? Ouch. IWas trying to avoid that !

Great, so it keeps the original look.

No need to change ratios ? Is it possible to fit an overdrive to a disco box....

Steve

One of the metric fine pitches. I have a tap and die for that size at work, but it MUST be a standard part !

Steve

I've had a quick look at mine without dismantling and it measures up a bit below 12mm. The pitch is also coarser than 1mm, I think.

Try a standard seat belt bolt for comparision 7/16"-20 UNF.

Thanks, just tried, but dia of seat belt bolt is too small and pitch too coarse.

Think I may have to resort to getting the dremmel out and removing the olives and then nuts off pump and replacing with nuts and olives off V8 unions. The olive will fit and the nut will. The V8 nut is VERY similar diameter but the pitch is different.

That's what I would have thought but no one seems to recognise it. I have even been into my local injection pump specialists. Apparently car manufactures are making there own sizes up so you have to get spares from them!

I am lucky to have a rolling chassis so i could offer it up to that first, make the mounts, weld the engine mounts on the chassis to be converted, put the engine in the vehicle, install gear box, tack weld the gearbox mounts and then remove gearbox and weld mounts properly.

yes no problem but about £900 ish. Remember 5th gear is like an overdrive though compared to lt95 gearbox.
