I need some help from somone who has a rb25det please!
I am trying to figure out what i will need to modify to fit this engine in my project.
The information i need it
1: the length of the engine from the alt or power steering pump to the back of the block.
2: I need to know the length of the trans from the front of the bellhouseing to the tailshaft.
3: The length from the front of the bellhouseing to the center were the shifter mounts on the trans.

Please if you know were i can find this post a link for me, or even better if you have one i would love it if you could check it for me. Any help is appriciated, I the only info i found is that the block alone is about 26 inches. :gotme

I can tell you this:

If any of the cars in your list are the intended recipient, forget it.

It's a snug fit in a 240Z, which has over a FOOT more room. I can measure mine when I get home.

p.s. The RB trans is HUGE - you asked about the length, but the width and height of the trans are also an issue - it BARELY fits in a Z tunnel, and would completely overwhelm any other Datsun.

thanks AZhitman, The intended recepiant is my 72 521. I know i can make it fit thats not the issue, i just want to get the dimensions so i can see how the engine would sit when its all done. I allready made a new firewall and recessed it about 4 inches, and i was planing on making a new trans tunnel anyways. I would be very greatful if you were able to get some measurements for me. I am serious about doing this, i have a build thread on here. If this wont fit i will either go with the vq35de or the vk56de, or meby even the vh45de but i would rather do the rb25det and get the rb30de bottom end.
Thanks again AZhitman
