I just put an S54 into my e12 racer, I spent more money than I care to mention, and it took 10 times longer than I wanted, and Im still working on the bugs
the e12 would be similar to to e9 in some regards
a short list of immediate problems
you will have to go to a tilton brake set up
I even tried a booster from a geo
the intake hits the master cly
the exhaust will hit the stock steering linkage
the stock oil pan (s54) will not fit inbetween the swaybar and subframe
the electronics, you will need to speed at least 3k to get around EWS
or use motec or similar system, I used a vipec
electric throttle
you will need to find a compatible trans, witch means custom driveshaft
We removed the e12 subframe and modfied a n e30 subframe
then used an tubular custom e46 based suspension
with an e46 rack
then used an e34 525 oilpan and oilpump
made a custom speedway bar
then custom exhaust
fab up a cooling system
etc, etc
My original plan wwas to get things sorted out, so I could build my CSL with a S54, but it was sooooooo much more than I expected thaat plan could be premanetly postponed??
if anyones interested I can post up pics or links to buld blog on bfc
