240hoke Posted May 2, 2005 Share Posted May 2, 2005 Hey guys, I've been rebuilding my 1971 240z, and im getting to the point where I need to start looking at either building my l28 or moving on to something better.... like a rb! i could build my l28 for 450 hp right now with just injectors and pistons but I'd like to move to something a bit more advanced. I already have the suspension/brakes/chassis/fuel undercontrol. Currently Im running GC coilovers, illumina struts, adjustable LCA's and t/c rods, suspension techniqes sways, subframe connectors, 8pt rollcage, corvette c4 disc brakes, jazz fuel cell, Walboro pump, yada yada yada. Sooooo before anybody tells me i need to upgrade my car before i drop in a rb there ya go. From what I can tell the parts needed for the rb25 swap are: - motors mounts (availible from austrailia ~ 115US) - rear sump oil pan, and rear oil pickup tube( both availible from nissan) - driveshaft and tranny mount must be fabbed. - Possiblilty of needing to use a greddy style intake manifold I already have SDS EM4-6f I was running on my l28. So heres my delimma: I am trying to do this swap on a semi budget, i already have everythign else taken care of on the car and I do all my own work, soo im trying to get this done in the 3K range. Most places around me dont sell just engines, you must buy the whole clip. Im in NC do you guys know of a place I could find one of these motors? Also what kind of power figures can I expect with this motor, for just tuning and turning the boost to ~1.1 bar? Okay While Im at it another question -- Whats the redline of these motors, I know stock its 7K, but msot people are turning them to 8K am I correct or does this require some headwork? If I can find a motor for a good price. i hope to us this thread to document my progress wit hthe motor since here isnt much availible....

Sparks280zt Posted May 2, 2005 Share Posted May 2, 2005 I think you should sell your l28 to your best buddy Quote Link to comment Share on other sites More sharing options...

240Z_Master Posted May 3, 2005 Share Posted May 3, 2005 From what I can tell the parts needed for the rb25 swap are: - motors mounts (availible from austrailia ~ 115US) Motor mounts many options, either place the motor in an undesireable position by using the 200ZR mounts (avail from Nissan), or go Brad's Mounts, Infinity Machining Mounts, or those Aussie Mounts - rear sump oil pan, and rear oil pickup tube( both availible from nissan) Part numbers are all throughout the RB Forum and are available from http://www.nismoparts.com for $183 Shipped (Pan, Pickup, and O-Ring) - driveshaft and tranny mount must be fabbed. Trans mount will be fabbed (there have been many ways on this forum, 2 that i've seen). Driveshaft either cut and welded or a nice new one that's custom length. - Possiblilty of needing to use a greddy style intake manifold Stock manifold, depends on if you plan on a RB20/25 or a RB26. RB26's you wont really need a new manifold. The RB20/25 wont need one either, but I would highly recommend that or get a custom fabbed one like the other guys on here. Too much piping if you ask me with the stock ones. (My friend did a RB20DET with the stock manifold, you can see about as much piping in there as the Alaska Pipeline) As for me, i'm still working on my RB25DET. GOOD LUCK!
