Homer mounts are useless, oil filter housing needs to be deleted. Custom alternator mount/tensioner as you won't be using the A/C compressor . Intake and exhaust manifolds are useless for rwd. Returnless EFI system needs to be replicated in the 240.
Fully aware of differences
Homer mounts give you mount points in the correct place in the engine bay for some migged steel plate mounts off the rn block are not that hard for anyone who has ever done custom fabrication before
I have a complete b6304 mockup setup that I always toss in first
This gives a reference point of center for the crank
Then you just align that with the new block and tac it together
It's more time taking engine/trans in and out than anything else
The na exhaust manifold can be used with some modification, much like using the 850 na manifold, it's not that hard to modify it in an ugly way to have something that works pretty well
Previously I just used the na flange and a cheap b230 tube header and added an extra tube after heating up and bending the other 4 to weld onto the flange
Return less efi is easily done by transplanting the p1 pump or most any modern pump into the 240 tank as a single pump setup using the rn motor ECU setup to drive it ... this is the easiest part of the entire thing... you just don't use the return piping at all...
Otherwise... if you go to aftermarket EMS... you can remove the fps and drill and tap for a return line and have a returned system
On the alt... previously just used a nose extension on the alt to push it out to be even with the crank pully
The only reason the factory design is stupid is lack of room on a p1 engine bay... a non issue on the 240
I'm pretty sure I used a funky BMW tensioner on the alt belt that I found in the local pnp
On the oil filter
I had something water cut as a flange and welded on some an fittings, the hardest thing was the bit of CNC milling I did on a manual mill for the oring like gaskets
Still... not much effort because I had a spare assembly and could work through this...
Intake
Possibly the most expensive bit... I got a puma manifold and cut off both ends and reversed because it seamed less effort than making something else fit
The uglier alternative is using parts from a b6304 setup including the squid which will bolt on... badly... with a runner cut and shut and longer bits of rubber coupler to deal with the slight spacing issues
Ugly but works
The most pita bit is still modifying the b6304 pan... and or modifying the factory pan... that's like an entire day on it's own
So yes... there is a pile of prep work you need to do ahead of time... but actual time fitting is still not that much effort
Like I said... quick and ugly but working...
The last conversion I did was in 2007 before I came to Australia I'd have to dig for some pictures
