PD Conversion ( Now TDI Conversions)

[tech1889]

Thanks for the info guys.. Any more info on the engines.. what makes them so easy to swap less sensors ?? VNT Turbo from a pd lump ??

Thanks  be good to get as much info in one place

1Z works ok, in std form they don't rev as high as the earlyer motors

aaz's will tune well but good ones are near unobtanium.

the troublesome T4 started life as a 1.9 NAD.   had an AAZ and a 1Z in there  turning them up  in a van full of heavy welding/spannering kit and that often had a trailer behind it dosent appear to be the worlds best idea ( it ate the bottom ends )   once youve done the usual stuff make a manifold and swap the turbo i robbed the turbo of a LT35 and it seemed to like that,  it also seemed to go a lot better with a log manifold i knocked up in  the shed.

if you get one from a mk3 golf they will swap straight over everything wont they ?

what about pd turbos fitted to this engine ?

Check what mounts they need, I think it's probably from a MK3.

AAZ is straight swap for the most part being a mechanical TD lump if coming from a MK GTD, no silly sensors and no ECU iirc. the 1Z is a TDI so I assume it's more involved but not as silly as a PD, I never really looked into doing it but DH said it would be the better of the two.

Or you can be nuts and do a Franken motor as the yanks call it and mix a 1.5D from a MK1 and 1.6TD from a MK2 (I think you can mix these using a 1.5 block with 1.6 head?) or 1.6TD block with 1.9 AAZ head - try explaining that to an insurance company




* some info is probably wrong, I half heartedly looked at doing it about 2 years ago knowing I couldn't really do it because I had no garage and my GTD was my daily hack.

[tech1889]

^^ That is interesting but as you say mixing 2 engines from two different mk's would make for a fun conversation with the insurance company..

So let me get this right the AAZ is mechanical injection and no ECU.... And the 1Z engine is a TDI engine with less sensors (likely) than a PD but it has a ECU which makes mapping and such much much easier ??

Sommat like that Sure danny can clear up some info about the 1Z

Damn you






















got me looking at GTD's again

bit suspect about the 'oil cooler' leaking oil into the water probably a glown head gasket or crack between the oil and water ways.

[tech1889]

Wouldn't worry about oil cooler just change it and do a coolant and oil flush and would be sweet.. IMO Diesel tuning is turning into the way forward especially with the price of petrol nowadays.. Ive decided what car i want in a few years time when prices reduce.. a BMW 335D 340bhp with just a remap and still 39mpg 

Sorry Jay im terrible aint i

aint u stuck a 20v in my old car yet, do it. or just get a motorbike which is much more fun
