agent75 37 Report post Posted November 11, 2017 forgetting the M10 here is the scene as I know it: there are 2 gear boxes and two bell housings between them. the 6 cylinder bell housing and the 4 cylinder m40 bell housing. the gear boxes are g260 and g240. The 325 has the g260 and the 320, 318 and 316 have g240. 6 and 4 cyl same pattern but they bolt up on different angles. 4 cylinder bolt angle same as M50 and M52 so 4 cly g240 okay for the swap. 6 cylinder bellhousing will make gearbox and gear stick sit on 10 degree angle on m50/52. this makes 320 shitest conversion gearbox as you'll have the weaker gearbox with gearstick on angle. Only the 325 has the medium case diff and larger half shafts. Both the 320 and 318 316 have small case diff and small half shafts. the bigger front struts are a lottery with virtually no chance on 316 318, some chance on 320 and very good but not guaranteed on 325......I think 1 Quote Share this post Link to post Share on other sites
