I was looking through the PET catalogs for the early 911/912s and later 911s and saw that there is a ring gear and pinion shaft listed with a ratio of 7:27 or 3.857:1 which is taller than the 914's stock 7:31 (4.429:1) ratio. Will this ring gear and pinion shaft work in the 914's 901 tranny?

So I guess you don't recommend that people use the stock 901 with a V8 engine swap either?

(IMG:style_emoticons/default/screwy.gif) (IMG:style_emoticons/default/biggrin.gif) how many times have you done this? are you traction limited? NOBODY has said the transmission will blow up the 1st time from being abused.....yes, it is coping with the abuse, but for how long?? |
