Title: AAZ O2A/O2J Suggestions
Post by: Big Daddy Roth on March 07, 2015, 06:25:54 pm: I have a 95 B4 AAZ. Fresh engine, holset he200wg, giles pump, blah blah blah.....

The CHA trans is geared way too low.

I'm wondering what others are using for a cable shift trans.

Post by: Big Daddy Roth on March 10, 2015, 09:33:40 am: I put a VR6 R&P into my CHA trans. I'm finding that cruising around at 50 - 60 is a high reving 3rd or bogged down 4th. I also don't shift into 5th till 120.

I'm thinking a Rado g60 trans is a happy medium with the 3.6 R&P.

MTDI or TD? The idi doesn't Rev as high as the TDI head does.

Post by: vanbcguy on March 10, 2015, 01:39:21 pm: M-TDI but the rev range would make an IDI quite happy.

The CTN has the lowest numerical gearing of any transmission in the family. Very diesel friendly and great for the highway. Not the best for drag racing.

Post by: burn_your_money on March 13, 2015, 09:18:50 am: Giles ran a CTN on his AAZ with a k14 and also with a T3. It did fine. I drive closer to 100 on the highways and was usually in 4th when I borrowed his car but Giles made better use of 5th.

No, seriously. Its not a big change, but will it make the 4-5 shift too wide?
