R33 Rb25det Series 2 VS. R34 Rb25det Neo

[pricer-1]

So I have been looking into a RB swap and I think I want to go with the R34 Neo but I have a few questions about differences between the Neo and Series 2 engines. When it comes to upgrades or even just OEM parts will the parts for a Series 2 motor work on a Neo? Physically what are the differences? Also what parts should I consider replacing before installing the engine into my S13?

To tell you the truth parts are gonna be impossible to find if you decide to swap a RB25 neo. I currently have a RB25 and it cost an arm/leg to get parts for it (located in Japan). If you got any questions about RB engines you should check out http://forums.skylinesdownunder.co.nz/ (http://forums.skylinesdownunder.co.nz/) for more info. Then search for Zilvia members on here who actually had a RB25 swapped into their cars. Good luck!!!
