Hey everybody. I just got the bad news from my insurance company and they're going to write off my darling '03 ALH Golf. Sad day. But that has me looking for what comes next! I've always had a soft spot for the A4 wagon (especially with Quattro) but I can't go without my diesel fix.
Right now I'm trying to gather as much information about swapping a 2.0T TDI engine from an '04/5 Passat (that's a BHW right?) into an '03 Audi A4 1.8T Quattro wagon. Both are available locally for me which is a huge bonus.Price for the engine is ~$950 (I'll aim for less), sounds like it has everything but the transmission (so probably no clutch), and it has "around 200km on the engine". I'm assuming they mean 200 000km.
My plan is to work on the motor and aquire parts for it through the winter and enjoy the 1.8T for a bit (while crying at the gas pumps). I'd like to: BSM delete and replace timing belt, swap to the AWM 1.8T oil pan for the level sensor and block turbo oil return, keep stock turbo & injectors, clean the intake manifold if it needs it (just did that on my ALH) and maybe an EGR delete. I just want something that works, I don't need a coal-rolling powerhouse right now (though I know I'll really want that eventually).
I've read and reread through as many other threads over the past few days as I possibly could before posting, but I still have sooooo many questions.
First off, can someone clarify the platforms of these two cars. I believe the Passat engine would be from a B5.5 and the A4 would be a B6, but what differences does that actually make? I believe the mounts are direct bolt on, and it's only really the wiring that makes it difficult right? Oh and the fuel pump. I'll probaby just add a FPR and then run the loop back into the tank like I believe GoremanX ended up doing.
Second, from GoremanX's posts early on, it seems very likely that the A4's differentials are all 3.899 final drive from the factory right? What then is the smart choice for a matching transmission? I assume the gearbox for the 1.8T will be too short. I'm getting lost between all the 01A's, 01E, and now recently I saw something about an 01X. I'm not picky about 5 or 6 speed, that'd be more about price. What I'd like is a direct bolt-on for the motor and into the A4, use the stock DMF from the 2.0T to save syncros and vibes, and have tall enough gears to not run out of revs and keep things efficient. So what are my options? It sounds like Franz is the go-to on this front if I need supply
Third, QuickTD's thread ended with him recommending an AWX EDC15P ECU, AWX wiring harness, and even the AWX manifold. Most seem pretty cheap on eBay. The result sounded like a much more simplified swap. He mentioned having to find a left-hand drive harness, are they generally going to be for right-hand drive models? Also, is the manifold swap that important? Is tuning the EDC15P necessary for a stock motor or is that only for different turbo/injector combos? Is it possible to use the stock 1.8T side mount intercooler with either the stock 2.0T manifold or this AWX one?
QuickTD's thread also mentions having to relocate engine accessories to the left side using a whole bunch of parts (BPW, BRM, AMB, and ALH are all involved), but I can't find anyone else that had to do this? So what's up there?
There's probably more I'm forgetting to ask but this will get the ball rolling! If you have any advice to add that I didn't ask about, feel free to leave that too. I know need as much information as possible. Thanks a bunch for reading all that!
