RB25DET into 1st gen maxima??

[phleb]

I was just wondering if anyone had done this swap and if it would even be possible. Sort of like putting a 1jz into a cressida. Swapping an inline six for an inline six. I don't know much about maxima's though, would there be anything that would need to be cut or changed?

I'd imagine it'd require a good bit of custom work. The engine bay is laid out for a straight 6, so there's that benefit, but I imagine that's the only similarity. The motors will have different mounts, and I don't know if transmissions are interchangable, which means those mounts may need to be fabbed as well. Very interesting idea. It'd be very cool.

Find me a first gen Maxima, and I'll find out for you.

Very interesting MOD, I was kind of thinking along those lines as far as possibility goes. Things like motor and transmission mounts. So stuff one in there and chain it?? I kind of figured alot of custom work. I think it would be a cool idea too, I don't know if you've seen some of the 1jz cressies, but those things are pretty bad. I read that one guy out of Australia was running IIRC mid 13s on a pretty much stock 1jz and they apparently fit pretty well. I wouldn't mind trying the maxima swap, I just don't have any money for such fabrication.

A couple more things I thought of...Driveshaft, differential. Driveshaft length might be affected. Also, you'd probably want to switch to a more performance oriented differential. If you want a monster drag car, go with a first gen wagon, since they have solid rear axles. Otherwise, the sedan has IRS, and it's probably fairly easy to swap diff/axles with it's contemporary Z car (if they're not the same already) or something along those lines.Nissan makes things really easy because they do so much parts sharing.

I've never seen a 1zj Cressie, but I've heard about them. I'd really like to do a 7M-GTE Cressida, though. Another good option (and far more common) is the L28ET in the Maxima. Very simple to do, since it's physically the same as the L24 the car came with, aside from the turbo.

I've dreamt of a big-L-powered first gen for a long, long time. I never thought of the RB as an alternative, though.

You wouldn't happen to have any pictures of an L28et into a 1st gen do you? That sounds like a great swap. What kind of modifications need to be done with that? You said they're physically the same, so would an L28et bolt right up then? This sounds pretty interesting, I searched L28et and found a couple of 400whp ones on google. Just didn't see any in Maximas.

The L28E(T) is a very straightforward swap. The L28 bolts right in. Most people accompany this swap with a 5 speed manual swap as well. You just need the fuel injection computer and air flow sensor from the 280ZX. The Maxima L24 heads are also different than the Z L28 heads. If you do the L28ET swap, you'll need to use the Z heads so the turbo exhaust manifolds will work. If you just go with the N/A L28E, you can use heads and manifolds from whichever car you want.

Should be doable though I've never seen it done. The RB inline 6 is supposed to have been developed from the L series inline 6. People have swaped RB20DET/RB25DET into 1st and 2nd and 3rd gen Z cars. Since the 1st gen Maxima shares many components with the early model Z you may want to ask one of the Z car owners that have done the swap for help.
