What diffs fit E30?
The E30 was fitted with two sizes of differential. The larger is known as a medium case (Type 188), and was used on 325 models. It has a crown wheel diameter of 188mm. They differ in length but not width, and therefore are interchangeable without changing drive shafts.
Are E30 and e36 diffs the same?
Registered. the diffs are the same, but the casings are different. but casings are different on them all, so that has to be changed.
Will Z3 diff fit E30?
The Z3 uses the same differential case as the E30, and is therefore a direct swap. This is especially convenient for the lower ratios Z3 diffs can offer; the 3.15 is a particularly popular unit.
Are all E30 rear subframes the same?
While E30 subframes are all functionally the same fit there are minor differences across models that we do not differentiate between.
Are all E30 front subframes the same?
How to tell difference between E30 and E34 diff?
To tell them apart, count the bolts on the back plate; six bolts means it’ll fit an E30, eight bolts means it’s too big. 325 E30 diffs can be rebuilt with the crown wheel & pinion and gearset/LSD assembly from medium case E34 diffs.
What size is the differential on a Ford E30?
The E30 was fitted with two sizes of differential. The larger is known as a medium case (Type 188), and was used on 325 models. It has a crown wheel diameter of 188mm. The smaller case was used on 4 cylinder and 320i cars, and has a crown wheel of 168mm
What diff should I get for my 318is?
For example, a 318iS as a daily cruiser would be fine on a 3.91 to ease the cruising revs and help with economy. The same car driven for track days or just for more spirited country lane driving may do better on a 4.27 diff. To calculate the best diff for any given wheel or speed, [ check out this link ].
