Re: welded diff in an 020? (wide_mk1)
Welding a diff... if this is a track car, straight line, I guess yes or get a spool. If you are going to drive it on the street, forget that. Turning will be a big issue as the power will still be 100 % on both wheels (you ever had a cheap RC car with a cheap diff (if you spin one wheel forward, the other is locked going forward) and a RC car with LSD or wide open diff, if you spin one wheel forward the other wheel goes backwards or moves forward but slowly. Put both in the dirt and the cheap diff/straight diff car will be throwing up dirt off both wheels. The car with the wide open diff or LSD will throw dirt off one wheel most of the time. Put them on pavement (sticky wheels) and run them straight, the cheap diff car will grab good off the line, so will the other car with a wide open diff or LSD, now turn at good speed, the car with the wide open /LSD diff will make the turn normally. The cheap diff car will either try to go straight, scrub the tires, or flip as both wheels are going the same speed and trying to go the same distance. This is why the diff is important, the LSD would slip a little but just enough to allow turning without issues. Plus they don't blow holes in the trans case and bellhousing. I guess the big input shaft is on paper and technically is stronger than the 1.8L, but calloway turbo cars had the 1.8L trans also, they rarely had issues. The CHE/DFQ trans gear ratios will work good for a turbo car, even better in the Mk 1 body. throw in a LSd and you should be OK. The other issue though is how much power are you planning on making?
