high power dream, transmission impossible?

[Pat Dolan]

Yeah, the 2.0/2.4/2.5 inline 5 cyl engines are Audi bolt pattern, not VW 4 banger.   What tends to fool people is that there are some gearboxes out there with BOTH bolt patterns (all in Audis I think). 

For Nintendo's transverse 4 cyl, you want a TDI trans from a later model MkIV (easiest, plentiful) or if you want to make big power and have lots of gears, a DRW 6 speed - which is already geared to diesel revs.  I don't think you will be at 7 grand, but if you are stopping even at 6, gearing of gasser trans won't be that bad (and there are a LOT of them around).  Forget the 020:  it is very torque/abuse limited as others have pointed out.  Also getting harder to support.  If you go with a cable shift 02A, there are lots of clutch options, starting with VR6 gasser flywheel/clutch setup (straight bolt in to 5 speeds) to many aftermarket performance setups.

VR6 flywheel does not bolt to 4cyl, youŽll need 1Z or 2,0 gasser Passat/Corrado flywheel. Clutch will fit to both.

sweet, good info guys.  I plan to have the redline at or about 7k that doesn't mean it actually be just that.  I don't really know that much about the transmission side of the house or exactly why and how the diesel tranny differs from the gasser, I can only assume, as the gassers re much higher naturally, that that is the only difference but not sure.  This one for sale seems pretty promising but I don't want to end up with a bum transmission for this most auspicious of builds.  Everything needs to be perfect, and that is the number one reason why I started this thread.  Keep the good advice coming.

Thanks,

why dont you just get a pile of parts together and start building something? think the old school hot rodders had a forum to tell them how to put their cars together? i think not..

you claim you can do anything, so, i wanna see a car start developing here. start building, then drive it. it will be appearent what needs to be upgraded, cause its gonna be whatever breaks first..

you never get to build the car one time, then finish it, then never touch it again, it doesnt work like that. when you own a VW, you work on it damn near every day. sometimes a few times a day.

LOL, you got that right.  I'm a moron for having 4 of them.

Just to clarify, I was talking about the new-ish rabbit/Jetta 2.5 that came out in the MkVI- it's a normal 4-cylinder bolt pattern.  Getting it to work on a longitudinal dual-bolt patten Audi trans requires trimming of the gearbox bellhousing but that does not apply to FWD.


And, there is no difference between the diesel-specific transmissions and gasser transmissions, other than the gear ratios.  They are internally/externally exactly the same.

I wholeheartedly disagree, I am not Thomas Edison , nor do I have his resources .  I want to plan it, do it right, and do it right the first time.   My Machinist has brain cancer and will likely never be able to have steady hands again so Now I need a new Machinist on top of every other challenge that I face.  Thanks,

sorry, and thanks for clarifying.  My limited knowledge of transmissions had me confused

I have the same thing with vintage bicycles...   Maybe 3 1/2 rideable out of about 15

well I bought that one for 600.00 shipped now I just have to repair the small dent in the housing and off I go to th driveline specialists to make a custom driveline.

[smutts]

Have VW seen the light and stopped using those suicide rivets on the crownwheels?

[NintendoKD]

dunno

[theman53]

What did you buy?

Also, after talking to brokevw and learning from him, the problem transmissions were the MKII and up 020. The MKI 020 had rivots too, but they were harder than a woodpeckers lips. Brokevw said you don't want to try and drill those out. Afterwards from what I gather the ring gear is held on better.

[NintendoKD]

it's an 02q out of the next generation car (mk5 instead of mk4).  The transmissions are largely the same for your use, here's a link talking about the differences: http://www.sqsracing.com/files/fs_files/productdetails/200/manual-02m-q_55.pdf

Here's a link to the for sale thread.   He said he'd definitely take 500.
