I've read that r32 rb26's use the push type, as well as some early model r33 rb26's, but the later model r33 rb26's used pull type. My rb26 is a R33.

I'm at work right now so I'm not sure if my trans is push or pull type but i was hoping to get a few questions answered regardless.

Let's say i have a push type. From what I've read no matter if it's push or pull type the rb26 flywheel WILL work with the rb25 trans. And from what I've read the only issue with using the rb26 clutch is that it's too big for the rb25 bell housing. Could this issue be remedied by simply using the rb26 bell housing mated to the 25 trans? I've also read that you could grind the inside of the 25 bellhousing for it to fit. If the flywheel will work no matter what rb transmission wouldn't that mean the starter would work and fit any rb transmission/flywheel?

Also if i have a pull type...I have a question, with the pull type clutch couldn't i just use the pull type neo trans with the rb26 bell housing? are there any dis/advantages to pull or push type?

I've also read you can remove the transfer case and weld a plate over it, is this true?

My rb26 came with a sweet nismo clutch/pressure plate and flywheel, i'm hoping i can use these in the 25 trans. or if the transfer case can really be removed and plate welded over...i'd use that. I know this stuff as been covered, BUT there seems to be A LOT of controversy around this subject. I want some concrete answers.

note: i highly doubt the whole removing the transfer case and welding a plate over it. also i'm guessing the issue with using the rb26 bell housing would be the clearance in the tunnel? if so couldn't i just cut and weld, or would that mess with the integrity of the frame?

i posted this in tech talk but got no response... maybe someone will see it here, sorry mods, would just like some input!

did your rb come with the starter? from what i've been reading i can use the bell housing, i'll just have to cut and refab the tunnel. order a rb25det trans and try using the rb26 bellhousing, starter, and clutch...only reason i want to try is because it came with a nismo twin disc with plenty of life left. thats my plan for now. hopefully it works out
