I know next to nothing on these trannies. I have basically focused the entirety of my knowledge and brainpower on the engine. I know that my engine will rev fast and higher than stock setups, so the question is how to take advantage of the torque and power that will be available. I have a very rudimentry understanding o gear ratios and have sought out an 020 tranny with close gears I found here:
http://www.thesamba.com/vw/classifieds/detail.php?id=523552 (http://www.thesamba.com/vw/classifieds/detail.php?id=523552)
I also know that to go anywhere far I want to have a highway cruising gear that is fairly long and as of yet have no Idea on anything. FYI, I will be putting all of this under the trunklid of an 01' MR2 Spyder, in an MR setup with the engine and tranny facing the same direction, this will certainly take some doing, and I will need the tranny and engine+mounts to make the correct measurements. Any help on this particular front will be helpful as well.... like say....... arb, or anyone else who has put a diesel in anything but a vw.
thanks,
Kevin

check out brokevw.com
you will learn all about the 020

truckenwagen speaks the truth. I don't think anyone knows more about the 020 than broke.
Here's another good site about 020 gear ratios:

This will show you all the different gear ratios out there and let you play with tire sizes and stuff.

I love this forum..... did I mention that you guys are great ;D

Another good site with gear ratios on it.

I don't think the 020 will handle all the power your engine is gonna put to it.
IIRC Dave's build a few years ago (190ish HP) went thru two 020's in about a week. :'(
-
In Japanese, I would say "Komata na" This is quite the conundrum, I want a tranny that can handle the power and give me some quickness, the wide profile and low suspension geometry of the spyder will give me excellent traction, as well as the spectacular tires that I have put on it. The good news is that my car will be that much fasdter with out the added weight of a tranny. ::) Which tranny can I use, I project power to be in the 300 HP range, and that is a modest estimate, as well as having close to 400 ftlbs not 450. Is there anything out there for me? I would love to use a lim slip diff, but all of that power will exlode one of those in a heartbeat. Should I just go out for a getrag "for those not saavy, this is the transmission for the 2jz toyota supra transmission, stock it is good to about 1000 hp, no joke" LOL
-
so is there a tranny that will handle the power that I will throw at it? Without exploding? These numbers are no Joke, I really plan on doing this, and making this a reality. Without a transmission My car will have like waaaay more horsepower, you know, like mega weight reduction, that's like what, 100 pounds of weight LOL! ;D

I doubt these tranny's are much over 50lbs.
-
LOL! right then 50 pounds, well, in wight reduction I say the pounds come first, the tonnes come later.
-
the big weak spot in the 020 is the ring gear rivets.
if you replace the rivets with the special ring gear bolts they can hold plenty of power, and I would recommend an LSD if you want any kind of traction at all with all that power.
I like the Wavetrac diff, it not only is the cheapest LSD for our cars, but works better too, you can get them from Bildon Motorsport.

I know absolutely nothing about transmissions, any info? I need pictures folks I want to learn, but don't know where to go to school on vw trannies :-[ I need to learn to I have learned everything els eabout these cars/engines but know next to nothing on gearing and how the transmission works. Once I wrap my brain around something and have a firm grasp there is no letting go. I will look at Howstuffworks but I need particulars on this mission, in otherwards the 020, or is there a more suitable alternative. Also thanks on the advice on the diff, an LSD would be just superb,as opposed to a torque biased for lots of power and traction. I have wider bigger tires on the spyder, I have the 03'+ style rims which have larger wider in the front to give it a good profile and better traction. I'll post up some pics sometime.
thanks,
Kevin

i would be highly surprised if you are going to get another 110 horsepower out of your 1.6 than what dave cross could get out of his. dave builds these things all day every day, for most of his life. if you can squeeze 3 bills out of a 1.6, i will bow down and call you master, and be your first follower.
i, myself, do not think you can squeeze 300 horsepower worth of fuel and air into one of these things without the head exiting through the hood. i dont think the blocks or heads can handle it. i know people even have a tough time getting to the 250 horse mark with a 1.9, im pretty sure that the general consensus is that the 1.6 can be built to around 200 horsepower, and the AAZ can be built to 250, but anything after that is no mans land.
find a foundry, get some money, and get them to cast you an iron head. then you will be able to run 80 psi boost, or atleast thats what ive heard. i think theres some guy in norway or sweden or something with a cast iron head and 80 psi, on a 1.6 engine.
not trying to say you arent capable of building this kev, just pointing out that these engines do have mechanical limits, and the head is definitely one of the weak links.
no one else can get those kind of power numbers out of a 4cyl vw diesel, so how are you going to do it?
i would still love to see it done, please... PROVE ME WRONG!
-
I would love to, prove you wrong that is ;D, I would rather be safe than sorry, at least in the tranny dept. that is. I want to plan for the worst. I am in the Military after all. I did see the link once before somewhere else 8), so thank you, this is very helpful. Lets say that I never will attain the impossible of running 300 horses through this engine, that is just a goal, however lofty. I would rather have a transmission that can stand the test of time and my impatience. I don't want people not to take me seriously, but I also don't want to illude someone into thinking that I am some kind of Magician that can do things that no one else can. Foundry, you say? Hmmmmmmm....... well 70 pounds is quite a bit, but I don't think that I will, 40 is the target for right now.

thanks guys

Yeah I think when you push too much air/fuel into the these the precups like to break and/or fall out......if you can keep the head on that long 8).
-
it still might be a chore keeping a head gasket in the engine at 40 psi. if you want 300 horses, you should make a cast iron head.
-
I will look at other areas of improvement, I am still on for the ceramic precups, as well as some ideas that I have yet to present here ;D Let's see, dry sump 17/22 hybrid, mains girdle, lightweight flywheel, and crank, knifedged for less windage, chromoly rods, ceramic coating, port and polished head, plasma polished pd intake, big straight exhaust, all of the engine mods are in order, just a matter of getting a way to put all of that to good use to the asphalt.
-
transmissions are not rocket science. either put a bolt kit in an 020, or find yourself something more complicated. there are tougher transmissions than the 020, but none as simple and easy to work on.

By 17/22 hybrid are you talking about vnt's? How many are you going to run? One for each cylinder?
-
just one vnt, I will be using the linkage style control that another member here is using. The 17/22 hybrid will be a completely custom setup, complete with my own custom headers vnt 17 exhaust side with the compressor side from a bmw vnt 22. I have a friend of mine that works in a turbo refab place and will let me use the facilities for this purpose. I am not saying that the two will magically marry together, there will certainly be some fabrication involved, but this turbo will be the reason for all of the fuss, providing 40+ pounds of boost, if I so choose.
