200tdi into 1973 series 3 (historic)

Will DVLA let me put a 200 TDI in my 1973 diesel and still keep historic status . Simple question but i have no idea . I'm sure its been done . Thanks

Possibly not for MOT exemption, but it should not affect the free tax.

Yes no problem at all

Has this been done before (dvla not conversion ) Next is how do you do it.

Just read the info on the .gov site. It is very clear and easy to read.

They will NOT tell you about specific mods to specific vehicles. It is just general guidance. This means it is ultimately a self certification. And they have enough ammo that if they want to single out a vehicle/person. They probably can.

That said, the 200Tdi block is essentially the same as the original 2.25 petrol or diesel engines.i.e. it is the same engine that has been developed in an evolutionary fashion. Rather than being a completely different engine. So I think you are on fairly safe ground.

However, there are lots of ways to fit a Tdi. And a culmination of mods might lead to a different conclusion. But as said.... it is a SELF CERT process.

Yes. Talking to a chap the other day. He has a 200di (no turbocharger) in a 2a 109", and it is on historic reg.

As your vehicle appears to be on Historic Reg already, I should think the easiest thing is to send off the V5 with the "Change of engine number" section filled in, and they should just send it back with the new engine number on it.

Worth telling your insurer about it as well.

Be aware telling dvla may open a can of worms, dvla are very good organisers!

Many may series have been fitted with tdi engines, yet to read of any issues with authorities.

Only one to be sure you tell is your ins company

They are literally a drop in fit, if you have the battery tray under the bonnet (not sure on s3?) that will need a bit cut off and er thats it.

Its not the fitting ,thats easy its keeping its historic status and how far i can go with it i/e intercooler ,oil cooler etc

Engine change not a problem on a classic do not even need engineers report now.
Well worth informing DVLA as documents then correct.

DVLA won’t care about things like coolers. As said. Look on the .gov site. Radically Altered vehicles and the Rebuilt Vehicle regs good places to start.

As said it wont make any difference, do some research as its all on a points system, I think engine is one point, its the chassis and axles that are the main bits, its only when you start doing silly stuff that the one extra point that a different engine loses you may tip you over the edge.
Yes you can fit the whole shebang in the engine bay, like I said get googling it is all out there and has been done hundreds of tiems, Glencoyne engineering used to have a good article on it, plus Terriannes website with an excellent article by Glen Anderson whos i coped to do mine.

This is Glens car, http://www.expeditionlandrover.info/200tdiconversionIntro.htm

Dvla did the engine change from 2.25 to 200dti today no problems at all . I simply wrote them a letter and sent log book with changes required . Took 5 weeks though.

Just fit it and dont say anything....feel free to tell your insurance company.
Do you really want to fit it as a turbo version....a lot easier to fit as a DI.....ie without the turbo...still loads of power and a bit more economical...quieter and more in keeping when you open the bonnet.....I bet your insurance company will be a lot happier as well.

As you can imagine I fitted mine as the DI version....fitted 3.5 diffs and removed and sold the overdrive as it was no longer needed with having 3.5 diffs.

Have you seen Glencoynes fitting guide?

You probably need to read a bit more of the thread

BTW - personally I think a Di conversion is about the most pointless conversion ever!!!! Total and complete waste of effort.

EDIT - sorry, the above might sound harsh as you have a Di. But you have to 95% of the effort and work to end up with a motor with something like 70-75hp and lacking a fat torque curve. Keeping the turbo is hardly any extra effort and gives a min of 111bhp, but more like 130hp+ with a few tweaks and more importantly, lots more torque.

3.54:1 diffs also kill your low 1st crawl speed. Make High 1st a bit high if you tow and leaves a huge rpm gap between 3rd & 4th gears, which is right around 30mph. Making driving UK roads far more of a PITA than they should be....

They aint that quick even wit the turbo fitted, in fact quick is just the wrong word, more like with the tdi fitted they make progress nicely.

Insurance company says it makes no difference to risk. Didn't even ask for more money. Its not that noisy as the pump is tuned to standard spec ,its still got a series box so i don't want lots of torque very pleased with how it goes starts on the button with no heat even when very cold. Drive it gentle and i cant see any problems.

"quick" is relative. But I'd hardly say slow with a good Tdi.

GPS clocked mine at 92mph on a private road. And it was quick enough to chase down a herd of Lotus Elises going round the reservoirs in the Elan valley a number of years ago. In wet with 4.75:1 gears it was perfect in 3rd gear to drift round corners and steer it on the throttle.

For a modern car, no it wasn't quick. For a Series Land Rover however it was flippin QUICK!
