Just thinking about the idea... I'll need a new motor soon as this long toothed thing cries "no more boost!"

i'm pretty sure ya cant just drop the DOHC head onto the SOHC block, so you might wanna look at a good 2nd hand BA engine

there is a company out there that does DOHC conversions. cant remember the name tho, but its expensive. around 6 grand i think.

pretty pointless although, he does get quite a bit of power out of it.

the e-series motor is one motor, the AU is another motor, and the BA is another motor, nothing can be changed between them in the head, block, inlet and exhaust department for a start :) , have a nice day

actually you are wrong the 4.0 i6 are very comon throught the seires even up to ba... just different s**t ie dizzy coil packs etc

the au head will fit on ea and vice versa
the ba head will fit on the early falco on head
BUT u need to change water pump, timming cover, power steering pump
the pullys as well i think
then u need to get the twin varible cam working
and the coil on plug working
no mean feat

EED250 that company is krogduhl (spelling ) heads it a twin cam twin plug head for ford 4.0's and the old holden 186/202's

they are not the same we have put them side by side to see if they will go on. not a chance. they are a fully revised motor. but i suppose give it time and you never know what will happen.
we do have a few BA motors available but the electroncs & security is going to be the hard thing to get around. we have sold 2 turbo motors 1 for a EL XR6 which runs a aftermarket computer and a manual (easy) the other is going into a cortina with a Auto and he will be wiring it up will the BA stuff (what a nightmare) this job will take a bit of nutting out i rekon.

the block is physically the same AU-BA, so in terms of "bolt in" it will... problems will be in "bolt on accessories" and timing gear, VCT, and injection control etc....
if u ran a complete BA motor, with BA wireing loom, ECU and BEM somewhere it could be done.. but would be a s**t...

Are you sure on that. While I was having extractors fitted to my AU, there was a BA XR6 having extractors fitted and the mtr looked a lot higher than the AU. It might have been the head that made it look physically bigger.

I know for a fact that all the E series up to the AU can be interchanged as Spider is running an AU head, cam and rockers on an ED block. It was a straight swap. As for the BA I dont know but the physical dimensions of the head are a hell of a lot larger to its predecessors.
