Best of luck with your build, I will be checking out this thread regularly!
Not even close, unfortunately. A manual trans A4 1.8T has an 01A transmission with a 4.11 final drive. I already acquired a 3.889 rear end from an automatic 2001 S4, which is a bolt-in replacement. Also has the bonus of 108mm flanges for rear axle shafts, which are more resilient for handling the torque of a modified BHW. A few companies sell upgraded S4 axles that are bolt-in and can take all the beating I'll throw at them.
That may be true for a Passat, but a 6-speed manual is a bolt-in for an A4. The S4 came from the factory with a 6-speed manual (01E), and the mounting points are all the same. Swapping in a 6-speed is fairly common in the B5 A4 community. The diesel 6-speed is also an 01E, it just has different gearing. The only thing I'll need is an S4 driveshaft to go to the rear end.
Hey you're only an hour away from me! I'm in Georgia, just north of Milton. I've got a bunch of Audi- and TDI-specific tools that I got for this transplant. You're welcome to borrow them if you need them.Awesome! cant wait to see some progress
I am starting a BHW swap into my 05 A4 B6 1.8 in about a month!
I have gathered all my parts already including an EDC15P ecu and harness, injectors 01E ect
Ive had the A4 since last year in storage and I was really wishing I was driving it this winter as my mountain pass drive to work is not that easy in a FWD Golf!
Great car for vermont for sure!
Hey Thanks! I work at a Vag/TDi Shop up here so we have loads of special tools but thanks!Hey you're only an hour away from me! I'm in Georgia, just north of Milton. I've got a bunch of Audi- and TDI-specific tools that I got for this transplant. You're welcome to borrow them if you need them.
ugh... that's discouraging. I'm trying to get this done with a minimum of European parts, both for cost and convenience reasons. I'm also trying to keep the OEM intake manifold with EGR and flapper functionality.Nice!
I also forgot to mention if you go with a euro EC you you'll need an intake and EGR valve unless you're going to delete EGR and ASV anyway
Euro PD engines still used vacuum control for both those functions
Thanks! That confirms most of the info I got from tdtuning. You're correct, I do not have traction control on my A4 (and I'm SO glad about that). So I guess I'll be using the Passat harness and ECU after all. Sweet, more money savedBack on the engine control subject, using the passat engine controler should not be too hard
