Re: Engine change over

Yes.
Auto?
Use your intake manifold and ignition, it's better unless he's has the car chipped. Even so it'll be a lot of hassles making the EF run an ED computer.

Since the EF computer requires the crank angle sensor, you will need the EF crank; to the best of my knowledge the sensor will not fit an ED crank. You could either use the whole EF bottom end (preferred as it gives you the knock sensor), or whack the EF crank/pistons in the ED motor to avoid having to replace the head gasket.

I know it sounds a bit daunting, but is not hard if you've got the two motors out anyway. AFAIK dev5 is all head/cam work, possibly he might have gotten the extractors too?

Re: Engine change over

hmmm ok, just one last question he got the whole DEV 5a kit, so should i take the computer with the chip from the ed and put it straight in to the ef or will the computer have problems. and when they change the compression that means they change stuff on the pistons yea? if so can the ed pistons and stuff be put on a ef crank or am i just talking alot of jibberish ?

yea bit of jibberish there ...

EF computer will NOT like ED chip ....

chaging compression doesnt neccessarly mean changing pistons, you can increase compression ratio by decking the head, or decreasing compression ratio by using a spacer (evil)

I wouldnt even start mix matching piston, conrods and crank gear between engines ... just keep the bottom end in one piece ...


Just do the following:
- DEV5a head (ED) onto EF block
- swap over timing gear
- bolt DEV exhaust onto EF
- buy new chip for EF computer and use the rest of the EF gear

what u need to buy in addition:
- head gasket
- intake gasket
- exhaust gasket
- EF chip (not sure if u even need that one but what the hack)

thats probably gonna be much simpler and more efficient than swapping the entire engine. You probably find that the EF bottom end is in good nick, just that the EF top end is getting old.

Dunno about bolting ED tranny into EF, as far as i know they use different shifting programs, but i know that CAPA is offering shift kist for the EFs for around 375 bucks, which probably gonna improve the shifting a lot. And if u feel like spending some more $$$ get a newer/higher stall convertor.

Thats would be my plan of attack

Good Luck

The crank sensor (toothed hub) is located on the harmonic balancer, not the crank.
He will need the the EF timing cover though as it has the sensor.

Re: Engine change over

Why not just put the head into the ED motor?

Re: Engine change over

if ur mates ED has a DEV5 kit it has got a replacemnt head from JM. All the goodies of teh DEV kit sit in the head, naturally you want to use the head and its goodies in it. teh DEV series doent touch the bottom end , except the DEV6.
Thast y id suggest to just use the top end and leave the bottom end alone. besides destroying a bottom end with a NA car takes a while. Falcon bottom ends are good for 200kw at wheels, and last for ever ...
