Weight shift / Front mounted radiator

[my2000apb]

i went out to get comparo pics but my buddys stock motor location 3b coupe doesnt ahve front axles installed, we'll do that later and get good pics of his stock location and mine pushed back

just to bump this up, and i was asked to show how 4wd cossies were set out,

like this and they are very old, fragile and people are using Skyline stuff nowdays

1970`s design! this is attatched to the sump above that has a shaft runnning through it



here we go

Haydn got his v8 motor back 4" and down 3" in his 90/4k. Masses of other chassis work, but still a great read if you have some time.

IIRC there is some useful info on cv joint angles, I thought he found some that gave slightly more that others.

Thanks for that link. Amazing work.

I have started work on the project so will start a new thread once I am a bit further along. It will not be to the same degree but I hope 40mm and rest required from bumper and grill mods.

Thanks Andy...........4 HOURS LATER!!!!!! RS4K........nuts!!!! Motivated me loads to get tore into my 90!!

To use original quattro drivetrain you need to measure some things. Audi would put the engine further back if they could. At least It can be done a few cm with quattro drivetrain. I suggest you to lift the car up and bolt off the gearbox with the front driveshafts in, just to see how far back you can mount it before the angles get's unacceptable. This with someone in car could steer max to left/right and rotate the wheels and see how the joint's behave. Also after this you need to see how much further the splines moved out, or maybe the risk is that they be pulled out too much and destroys the splines on shaft/in hub.

Be happy to follow you as I will do the same research when I mount my DSY gearbox soon on my B4 sedan chassi.

Found the info on using other CVs for increased angle;

http://www.motorgeek.com/viewtopic.php?f=6&t=39901&start=200

OK here's the scoop on the inner CV thing I mentioned.

The EMPI axles (the particular ones I chose) have the same 28spline interface for the inner CV as the Audi shafts have (not all Audi shafts have this spline, it varies car by car)

The V8Q inner CV's are 28 spline and they will fit on the EMPI axles, however the cut is tight so they need a little gentle persuasion to go on.

So why would you want to do this? well the 108mm flanges on all Audi axles are pretty much the same, there are a few variations on the inner cap i.e. some are open and some have a sheetmetal grease cover. The V8Q inner CV's are thicker than all the others and have more longitudinal travel capability by a factor of about 70%. I believe this was done because the V8Q Auto's had that super wide trans so the shafts were really short and so the angles and relative motion were more extreme. So...... If I put these V8Q inner CV's on I will have more travel and more angle tolerance than with other 108mm inner CV's.

The down side is of course that I dont think the V8Q inner CV's are available new or rebuilt anywhere, if someone could prove me wrong that would be cool!

Some pics for proof:

Thanks . Good option.
