Alternative power-plants and transplants (GTi, Porsche, Subaru, Audi, diesel etc). Discussion and Q&A last answered over 2 years ago.

Right as the subject says, I have been offered a 130 PD Tdi with pumps, turbo, ecu, loom inc Clocks etc.. from an 07 Skoda VRS with less than 1000miles. I know what to do in order to fit it I.e fuel tank, diesel flywheel, bellhousing, re-gear on box, subframe, sump, etc... I am capable of making it work fly by wire. what I want to know is if the engine mounts on the Skoda block will tally up with the jx mounts ( I have been told it is basically a golf engine) or is this something I will have to fabricate once bolted up to the gearbox.
Thanks.

Ok I thought I had it sorted. Andy have you fitted a PD to a T25 gearbox? is the VW stud pattern different or just the Skoda version, or is it just that you cannot mount it at the right angle for the turbo and pickup pipe? I don't mind fabricating engine mounts or even a adaptor plate for the gearbox. I have spoke to Adian who can re-gear my box to suit the Pd diesel and I can make it fit and work using a VR6 flywheel or doing something with the dual mass flywheel (not looked too deep into it at the moment) and turning a new input shaft. The main reasons for going with this engine is that it is efficient has plenty of low down torque and is new i.e. less than 1000miles. Oh and it's at the right price. Having said that I am not going into it with my eyes wide shut I have budgeted £5000-6000 for the conversion and 12 months, with me doing most of the work.
My DJ engine is tired and parts are getting harder to come by, a Subaru conversion done properley with a newish low milage engine would cost about the same and return a lot less MPG and LPG is out of the question. I just wanted to know if anyone has done a PD conversion and can offer any advice.

Thanks James, I know the subaru lump can run LPG, I just don't want to. You can get diesel anywhere even of the beaten track, LPG is not so accessable in North Africa or Eastern Europe. Also both the WBX and Scubby engines like good quality petrol something else that cannot be guaranteed in some places.
Anyway I have brought the Tdi, Figured that I can't go wrong for £1000, I can break it for more than that if I change my mind.

Hi Andy, I would be getting the gears off the company we use who machine any ratios we want for our race gearboxs, they seem pretty confident from the information I have given them so far that they can machine a gear set for my Syncro gearbox to suit the power and torque characteristics of the PD Tdi engine. I have also been talking to a company who can supply me a 'stand alone' ecu which could be programed on the move which would then allow me to more suit the engines power characteristics to the camper.

Your wont win with a t25 box if you did manage to get all 5 gears sorted the bearings in the box are not big enough and will fail very quickly. They have 6 gears in the cars cos they need them to keep revs down. The pd engine will never be a rever, to much going on in that head, turbo also for rapid response at low revs not high revs. In my view only way to make this actually work properly is to find a different type of gearbox which would be difficult especially with a sycnro. You would be far better using the old generation tdi's which can be made to rev very high with greater flexibility and with better economy than a pd.
Cheers for the info Andy, will give it some thought. For what the engine cost I can make a healthy profit breaking it for parts if I go the old Tdi route.

you can make lots of money stripping them engines for bits
