I’m looking into putting a rb25 skyline engine into a 300zx. I’m just beginning to look into this and have no clue if this can work. If anyone could help me with some information it would be great. ---

Z31s had a proper crossmember. See Top Secret for Z32 info. ---

You may have some clearance issues with the hood as well… I can see maybe hacking into the floorpan abit too depending on how you mount the engine… ---

> [@BlueTurboEGG](#): > > You may have some clearance issues with the hood as well… > > I can see maybe hacking into the floorpan abit too depending on how you mount the engine… the Z31 came from the factory with an RB20det, the car was called a 200ZR (try a google search on 200zr). You’ll need this oil pan, as it has a rear sump. You’d do well to try to find a 200zr crossmember and engine mounts, then it should be a matter of figuring out the wiring. All in all I’d use another Z31 motor 😃 I suppose this is all assuming you have a Z31… haha ---

I thought there were different clearances for the RB20 and RB25?.. Assuming that this is still a Z31. ---

> [@BlueTurboEGG](#): > > I thought there were different clearances for the RB20 and RB25?.. Assuming that this is still a Z31. Well, all RB oil pans are interchangeable, but if you go to a rear sump from a 200ZR you’ll need the rear facing pickup as well. I don’t believe that Z31’s ever came with an RB25, they were well into the Z32 series by that point. ---

I was just going to say what all you guys did and than Jason had to post those damn nice pics!! 😃 I hear 200zr RB20 is pretty slow and the VG would kill it. An RB25 from a R33 will waken it up plenty and will be a very cool swap!!! Good luck man. ---

What you mean to say is he’s not afraid to take on a project if a customer has money. The good news that all he has to do is follow what somebody else has done, it saves a lot of trial and error and wasting of customer’s finances.
