hi,, have had a 13bt rx2 for many years

genuine rx2 ( not capella ) will require a custom sump made by reversing the pan on an rx4 13b sump ( cut shut )
the rx2 will require all of the pan bump to the rear


the stock GSL-SE pan will hit the banana shaped crossmember unless the engine is mounted higher than norm
( the GSL-SE pan having a mid bump )

vehicles made for RHD markets will need a custom turbo exhaust manifold to clear around the steering box
( s4 and s5 engines )
LHD ( US ) vehicles may not have the same issues, and may only require shifting the engine across slightly on the timing cover mount

and PS
s5 engines can use a flipped upside down stock turbo manifold
( oval some holes and make a spacer plate between turbo and manifold )
this will move the turbo forwards adjacent the front rotor , clearing steering box on most RHD early rx's

hey does this apply to me I have a 74 RX3 wagon just trying to get an idea of what I have to do to put 13B into it

rx3 has a straight cross-member,, so will use the GSL-SE 13b sump as is
-- it will however require a custom exhaust manifold,, as even the flipped s5 manifold will prove rather close to the strut tower
( and steering box in aus,NZ, jap and british vehicles )

only geniune rx2 and r100 rotary models have the banana shaped cross-member requiring the rear sump bump
( FA3TS and 1200 coupe piston models have a banana shaped unit too )

capella 616/618 cars have a straight member and are converted ala rx3 mount under swaybar with front bump


ie
-- if banana shaped steering cross-member fitted with rotary type mounts = needs rear bump sump

- if straight steering member with under the swaybar type rotary motor mount= front bump sump ( rx4 13b ) OR GSL-SE sump ( mid front bump )

if combination banana with swaybar type rotary mount
( Fa3ts /1200 conversions )
then sump needs to be custom,, or motor raised slightly with front bump sump or up a little more with a GSL-SE sump
( as motor is too far forward to nestle a rear bump sump )

how much higher than normal? i am putting a S5 TII motor into an Rx2 this weekend and would like to know about a few probelms i will be running into to speed up the process.
