View Full Version : stock xmember or r33 xmember

05-05-2008, 02:32 AM
decided to do a rb25det swap. im trying to find a kit that has mounts for the stock crossmember. i know that most require the R33 crossmember but i dont want to buy a entire front clip. if using the stock x-member is not encouraged does anyone know where i can get just the r33 xmember?

Save yourself some trouble and just buy the R33 crossmember. Engine fitment is easy after this. Well worth the money IMO.

I would say hit up one of the importers for a X-member like G-Dimension. You can also try some members that seem to have RB parts like driftfreaq or that guy from rb-performance, Otis, I think.


I have a set of Ruckus RB mounts for sale if you interested. here's a link to them:


Good luck either way.

i thought only the syko kit requires the stock rb25 cross member.

full-race makes an rb mount kit. it looks pretty clean as it seems like they are just custom engine brackets and tranny crossmember. You can utilize sr mounts so you can get any out there from a wide variety of manufactuers like nismo or kazama. you should contact to see if you can use sr/ka tranny mounts as well.

In the RB sticky it says you can use the automatic cross member if you can't find the r33 one

that;s the transmission cross member, im sure he's talking about the Engine cross member.

Do yourself a favor and buy the r33 Xmember with the Syko kit. I have first hand experience with both style kits and I'm here to say the adaptor bracket/usdm Xmember combo kits are trash and are a pain in the ass to work with.
