rb25det gearbox into a R31 silhouette


Recommended Posts

was wondering if a rb25det gearbox (out of an r33) will fit into a R31 silhouette

i know it will bolt up to the motor, but

is the gearstick in the same spot as the gearbox out of the r31

will the tailshaft out a r31 fit to the r33 gearbox, r33 tailshaft fit into the r31

(i know the r33 has irs while the r31 is live rear axle, but you never know, just look at how compatable the rb series of motors are)

if anyone has any experience with this or could take some measurements of the gearbox crossmember, gearstick and the length of the rb35det gearbox from the the back of the block so i can compare them to the r31 gearbox.

i want to do the rb30det conversion, 114kw(at the flywheel) is boring, but i would like some reliability in the gearbox department.

or does anyone know how much torque and hp the r31 gearbox can take.

any advice would be greatly appreciated

    • They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.
    • I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
    • Either way he still need those style of spacer to go into the manifold because the photo he currently has is not going to work 
    • You can just get the injector bosses, which allows top feeds to fit. He can use the same injectors without issue, like these (another option): https://rocketindustries.com.au/af59-2210-rb25-fuel-injector-inserts     The Racework ones look a bit better: https://www.nzefi.com/product/raceworks-lower-injector-mounting-boss-kit-for-r33-rb25det-s14-s15-sr20det/   You could also just get a similar kit like the Radium one by Plazmaman: https://plazmaman.com/product/nissan-rb25det-r33-billet-fuel-rail/?srsltid=AfmBOoogfYq49X0fu2Wdbf8yOf6zt9egyPAif_gn3Qr3G8hzAphhTgOkO70  
    • You need the kit turbo taipan has shown you because that manifold ia designed have side feed injectors
