R34 Neo Engine Into R33 Gtst

[candy33]

Hi guys, tried searching but couldn't really find much.

I got a 94 r33 gtst. I'm about to remove my engine so i can get my engine bay painted.

I got a spare R34 Neo engine lying around, wondering what exactly would i need to get it running in my car?.

and what loom ecu should i run. Main reason for wanting to swap is, engine is spare, newer and has solid lifters so i can run higher lift cams.'

Any help is appreciated.

Fit the r33 inlet manifold and injectors, fit an r32 or 33 GTR exhaust cam, then you can use your r33 CAS, fit the r33 throttle body, the rest should bolt up

leave r33 harness and ecu, install r34 engine completely. you will have to resolder two connectors (vtc, idle control). old style CAS can be modified (use your imagination and angle cutter (not sure aboutt right name for this tool)) to work with r34 ex. cam. i was lucky i have latest r33 with new style hitachi CAS.

everything else was straight forward i think. i`m driving enr33 with neo engine.
