Using stock transmission + 350.

[John]

I heard a rumor that there is a bell housing/adapter that will merge a V8 with your everyday s30 5 speed. It may be completely untrue, I wanted to just put this out there. Yay or nay? If it doesn't exist, it should.

[jhill]

Why not just go with a stronger 5spd? I don't really see the need for it. For some reason I get the feeling things would end badly doing this..

[GOTHALOSISM]

I know of adapters to use a GM 350 on an L block but not the other way around. Plus the stock 5 speed will get destroyed on the back end of that V-8.

Like the other guys said, you don't really want to put a transmission intended for an L6 on a V8. I think there used to be something made by Scarab, but has long since gone away. There are a few options much better suited for the 350 conversion, such as the Camaro T5 or T56.

A T5 can be had cheaper than any trans adapter I've seen, I got one from a 3rd gen f body for $150 on craigslist.

I would like to reiterate what letitsnow (et al.) have said.

 

The 280ZX and 300ZX turbo used a "World Class" T-5, stock. I would avoid those, unless you plan on spending a lot of money to get different internals for it, I believe they were offered by Tremec (Borg Warner at the time) to satisfy homologation into certain international motor sports classes (not sure?). Not that the Nissan 5 speeds are particularly "weak" by any means, it's just that the Torque "curve" (if you can call it that, it's more like a very gradual hump or a slightly angled line) of a V8 is going to be radically different from an L6, so they wouldn't have engineered the Z five-speed to handle it.

 

You can find Camaro T-5s or Mustang T-5s (be aware of what year mustang, they switched over to the WC T-5, at somepoint during the late 80s, I think), for really cheap at parts yards or even refurbished (I'd be surprised if you had to shell out more than $700, even rebuilt). They also have a wide-range of available "OEM" gear-sets/ratios, and a large aftermarket. I got a Camaro T-5 for my 383 project, got some aftermarket hardened internals, $900 out-the-door. The T-5s really aren't that bulky or heavy compared to the FS5W71, anyway, so it's not like you'll be saving weight by keeping the stock transmission, anyway.

the WC T5 came out in 88-92 after that it went to the t56.

Huh?? a WC T5 came out in 87.

 

The main difference is a bearing on 1st and 2nd instead of a bushing.
