Gearbox for Rb26dett

[Etgan_06]

Hey guys I’ve been trying to do some research and so far my chances are looking pretty slim. I’m trying to find out what the best gearbox would be for an RB26dett. Note that it won’t be a dett forever I’m taking off one of the turbos and swapping it for a supercharging to make a custom twin charge so it needs to hold up to a fair amount of HP and torque. Any advice would be great thanks

Rear wheel drive or four wheel drive?

Strongest r32/33/34 gearbox

I'd respectfully suggest that "strongest" isn't really enough to provide useful advice. What sort of power or torque are you thinking, and what sort of use (street, drag, race, burnouts at summernats??)

gonna be looking to push out at least 550hp and maybe 520 torque. It’s going to essentially be an everything car. I’ve built some decent cars before and had the privilege of working on a few of my mates cars with them. The idea is that it will be doing track, drift comps, drag (probably not very competitively) and definitely burnouts.

So..... nothing outrageous then. Just use the RB25DET trans.

Just use an rb25 turbo box

Yep at around 400kw the standard box is near its limit, some people kill them straight away, some people must be nicer and never have a problem. I'm running a standard 32 gtr (awd) box in my stagea at 400kw

Unless you really want to spend money on it, stick with the standard box until it breaks, and then put an aftermarket gearset in it (either syncho or dog depending on how unfriendly you want it to be on the street).
