R33 20e to rb25 advice

[C.callander]

Hey guys im new to the site and just seeking some information from the guru’s 

 

soi have a s2 r33 factory gts25 sedan auto and long story short it’s become a 20e manual somewhere in its life now im converting it back, ive been doing alot of research and cant find if the flywheel from the 20e and the crank pulley from the 20e will fit the Rb25, and can someone confirm id need a pink sticker afm and also if any blue sticker ecu works for does it need to be specific. But im sorted for everything else

Flywheel is the same. I would not expect the crank pulley to be the same, and I'm horrified that the 25 you appear to have bought did not have one on it. You might just have to buy aftermarket.

Pink sticker AFM, check. ECU? You need one with the right part number. I wouldn't base decision off of sticker colour!

The R33 did come with an RB20E from factory though I'm not sure you could bring one in. How sure are you that this is not a factory RB20E R33 with a badge?

There were a bunch of very disappointing R33s brought in with RB20Es. It was hilarious when people bought them thinking that all R33s were RB25!

Cool about the flywheel cheers, it has a crank pulley on the Rb25 but there is a chip in it and and it will tear the belt so was hoping it would be convenient lol, i was meant to write blue plug ecu not sticker sorry

Im in new zealand so we get a majority being a rb25de, but anyway my vin plate says rb25de and also the nz vehicle check site confirms stock rb25de, and it was a friend of mine that put the 20e in as he bought it as a rolling body then just put stuff he had laying around in it

Early r33 25de would normally have a green sticker afm, s2 would have pink, can change plugs though depending which loom you've got now, any 25de 33 ecu should work
