B30E or F?

Lesky · Dec 25th, 2009, 21:19

In my last thread I posted the lastest with my 164. After doing some perusing for parts online, I noticed that everything is listed as B30E. Will B30E parts bolt right on to the B30F? Also, what are the primary differences between the two engines? I searched the forums but didn't come up with anything.

The B30 F is a low comporession version for low grade fuel , the mecnanical bits and pieces would be the same depending on what you need .

B20F · Dec 26th, 2009, 10:22

The headhight, measured between head joint face and face for bolt heads, from a F is 3.42" (87mm) a E is 3.34"(84.9mm), the headgasket for a F is thicker as for an E to reduce compression ratio from 1:9.5 E to 1:8.7 F. The only other differences are the MAP sensor, the ECU and the distributor which have a slightly different centrifugal advance curve. All the other parts are the same.

No knowledge on the 3 liter engines, but with the B20E and F, a lot of parts were different originally. At least they had different numbers. Nowadays, replacement parts can be interchanged. The differences must be small. I am using a MAP from a 164 in my 144...

The maps from the 140 B20F and the B30F are the same, see list:
MAP sensors types with Bosch part#. But most are interchangeable, indeed small differences between the various types. I think best is not to interchange between E&F.

I thought the B30E had 10:1 c.r. Is that wrong?

I always thought that too, like the B20E may be different in different markets though ..
