R33 With Blown Motor

[NeilC]

A lady friend of mine has an R33 sedan and has blown the engine. She has been offered a complete de Neo out of a wrecked R34. Did a bit of a search but didnt get a definative answer. A couple of questions:

1. Will it fit up to her auto box.

2. Can it be made to run on the R33 ecu etc. or will it need the neo ecu and a rewire.

3. Any other mods needed.

Sensible answers please fellas I just need to know what would have to be done if its possible. Engine is in really good nick I am told and she can get it for very low dollars.

S1 and s2 r34 ran a different auto so the 33 ecu may not like that, depends on the donor engine.

Neo ecu and rewire probably best option

it'll bolt up to the auto, will run off the 33 loom & ecu if you change plugs, cas wiring & maybe coil wiring, assuming the 33 is a 25de not a 20e

changing loom & ecu would be better

^^^Like he says - if its same as the Stagea the R33 auto ecu is in the main ecu unlike the R34 so you will need to keep the R33 ecu and loom and adapt the Neo to suit if possible. You may be able to re use the R33 coils and injectors where they are different. I am not sure about the VCT differences. If you want certainty you could probably pull the head off the R33 if it is in good nick and put that on the Neo block and then it should be pretty straightforward.

Thanks all. We ended up not going that way. Sourced an engine out of a wrecked R33 in Sydney. car now back on the road. :-)

sorry to argue but when i put my neo in my 33 i had to get a new loom made up and had to run an r34 gt ecu.
