1350 Rear diff flange options
tidi0x replied to tidi0x's topic in Suspension, braking, tyres and drivetrain
lol, I’ll get right on that. 👍. In all seriousness, yeah probably the only way forward. -
With my CD swap I am going carbon driveshaft; I want my driveline as sturdy as possible; however one thing that keeps bugging me is the rear diff flange limitations of a 1310 yoke. I have seen and adapter for the 350z R200 that lets you run a 1350 yoke. However to the best of my research abilities the 350z R200 pinions are most likely incompatible with S/R/Z32 R200 diffs. Am I wrong? are there other options?

I made more progress today. I followed the Mazworx instructions for the SR trans, Marked a line 1/4in in from the second rib on the housing; that cut went well using a sawzall and a grinder. However I want to note, the bottom two bolts are very close to the bell housing, I accidentally cut a bit into the aluminum there; should be fine, but I overlooked it, its easy to f**k that up. After that I circumsized the input shaft 3/8in and beveled it; then assembled the housing on to the trans. That part was easy, just need to RTV the bottom 4 bolts, and use the two Allen bolts of the bottom. One thing I noticed about the bell housing bolts that were included, there is 4, and one is longer than the others. I am not 100% where each needs to go atm. As for the clutch fork and TOB; the new one with the CD is near identical to my old one for the Skyline so I plan to use the new CD kit. As for how the trans in... It was fairly easy. I was able to get it to sit in at a 1* angle; there is no clearancing issues from the bell housing or the top, The only area that is a problem is the mid plate. On the passengers side the mid plate bolts are hitting the trans mount; this is the only interference, I might be able to shift towards the drivers side, or smooth down the trans, or bash the mount a touch. Either way the fitment looks good and I'm fairly happy for now; ill play with it during the week. I also measured from the face of the output shaft area to the diff at ~57 1/4" or 145.5 cm (not a final measurement). I am debating my DS options. Pics attached

I am currently in the process of CD swapping my R33 (I cooked a band new R34 GTT box). I was hesitant to attempt it and looked for alternatives (8hp, T56, dogbox stock box) until I saw Mazworxs released the RBVQ bell housing adapter, which will let me run my twin-disk, and I assume better overall clearance. Anyways I am in the middle of swapping it in; I wanted to share pics of the clearance if anyone else is looking to the Mazworxs adapter. at 0* engine angle (pink socket) I see about 14mm of clearance, and at 3* (red socket) I see 20mm of clearance. I'll be chopping my CD tomorrow and attempting to set it in more permanently, then move onto mounts. Pics attached.

rb25det with 26 internals first start mapping
tidi0x replied to tidi0x's topic in R Series (R30, R31, R32, R33, R34)
Thanks guys, I'll be sure to use the link and the rb25 base map and change the capacity for first start. -
I am currently building my S2 25det from my R33 with a 26 crank, nitto I beams, and 26 CP pistons. I have a G4x PNP which I intend on using with a brand new loom from wiring specialties with r35 coils. However when it comes time to do first start since pulled the car down from bone stock I want to drop the built engine in the car as stock for first start because I know those parts WORK and I do not have to diagnose anything with new ecu, loom, turbo, intake etc.... I have no issue running the G4x on first start, but I do not know which base map to use be it the 25 or the 26 map, so my second option (And somewhat preferred) is the stock ecu, but I am concerned because the stroke is longer technically the ignition would be slightly retarted and I do not want to risk knock or detonation; Obviously I do not intend to beat on it, but I want to put light driving load accel and decel on the car to set the rings. After first start and drive, I will tear it down and run my turbo, intake mani, G4X and take it to my tuner to get the tune. Am I safe to run stock ecu for first run and drive? Also can someone please validate that for a 25 with 26 internals I need to run 26 Main bearings.... I have found two threads that talk about it with no SOLID answer.
