Makes a good engine doner for a 320(use 320 head,though).Sell the diff to some nutter who is putting an m30 into an E30.

Aha ... i know a thing or two about E28 acceleration and rust patching!!


Many so called "car experts" say these 525e's are slow.
If they opened their f***ing eyes and looked at the stupidly high gearing
they would see why.
Give these cars a chance!!!
Fit a "normal" differential ... then see what happens.

Remove the factory 3.06:1 differential (giving a 0-62mph in 10.4 seconds).
Fit a 3.91:1 differential ... suddenly you've got a 0-62mph of around
8 to 8.5 seconds.

Its all good news with the old eta blocks .... for one thing you've got 85%
of maximum torque available at below idle rpm (550).
Then you've got hardly any running resistance through the valve gear ...
you can turn an eta head over with one hand due to the light valve springs
... try that on a dual springed 325i head and you'll end up ripping skin off the palms of your hands!!
... Meaning the engine itself doesn't waste its own power literally turning
itself over.

The thing is with this combination ... you can stamp on the throttle and the
engine revs build instantly ... which sort of catches the torque convertor
unawares ... meaning just as 2000rpm is reached the car pisses off up the road big time.

One thing to bear in mind ... if you do a differential change, then start fitting
"I" heads with different manifolds, you'll be loosing low end torque,
but gaining high end power ... which actually isn't too noticeable providing
1st gear is quite low (3.91:1 diff).

So buy an ETA for £50 off ebay, change the diff. (another £50) then
go and upset some E34 525i's (350kg heavier for a start and they spend
the first 20mph building up engine revs before their power comes in ... by
which time old ancient eta has gone!!).

*Just don't expect to keep with anything more aerodynamic over 100mph,
unless you can fit a nose cone to the E28. winkeye
