Has anybody out there had any experience with this transmission swap kit?

I've been looking into my transmission options and came across this setup, but was unable to find anything about in on here. After looking into the 'Quick Time' bell-housing adapters for the T-56 I found on here that the few people that actually bought and tried the product had continual issues with it being compatible with the manual rear iron and starter 13b and was hoping somebody had some real install/use feedback on this.

I was able to find another thread on here but it seemed to be related to the product development and testing, where as it appears on the Collins Adapters site that the entire thing is available as a kit now.

No experience with it, but seems to be an interesting product. Sucks that it's designed for an auto bell housing, but that's not too bad.

Will definitely require some custom work to either make a trans mount or a new PPF.

I would do some digging on the 350/370z forums and see what the power capacity of the transmission is.

This is brilliant. The transmission from the 350 is reasonable but not nearly as good as the one used in the 370Z. The 370 has been out long enough for there to be some boxes that will be easy to get your hands on.

My questions would be three things...
1) Trans mounting as Dale stated.
2) What does the final gearing look like when mated with the FD rear end (and is it good for our use) and what's the spacing?
3) Is there a way to get the "auto throttle downshift blip" to work on the rotary engine? Sure, it might be unmanly, but it's a pretty darn cool feature the 370Z came with. Never got a chance to try it out but I always thought it would be a neat thing to have (especially if the wife drives the car sometimes). Anyway, not sure where that feature resided (likely in the 370Z ECU) so if it's not on the tranny itself then it's a no go.

Either way, I like the notchy positive feel of the 370 tranny. If it doesn't cost a fortune I'd love to have one under my FD.

 

Other question I would have is what is the final length of the assembly? Or more importantly, does it differ from the stock transmission length? I didn't see "custom driveshaft" in the list of required parts but that's not necessarily confirmation you won't need one.

And now I'm wondering...is a PPF even needed with something like this?

 

I think Blackadde// is running this, build thread here:

As I understand the folks who worked with Collins to get the adapter built are also working on a true "kit" that would possibly include an adapter to the factory PPF which would be perfect.

The shifter apparently is located further back (like most 20B concersions) but I've seen an aftermarket shifter mechanism that relocates it.

Once this is a true kit, it will be amazing. The power capacity is something like 800 hp, and the ratios look great.

There are some threads about it floating around the 20b, single turbo, and other Tech sub forums.

Very cool to see someone using this already. Interested to see how things turn out for him.

For anyone interested in the SynchroRev (auto throttle blip) feature I referenced earlier; here's more info on it.

The feature isn't present in only the transmission. The ECU is a big part of it along with some extra sensors not on the tranny like you guessed.

 

Yep, after finding that article I posted I figured that out (that's why I posted it). Seems like the only sensors not on the tranny is the one for the clutch but I'm certain that would be easy to retrofit. The ECU (which is surprisingly mounted on the top of the tranny) is a big part of it as you said. I wonder if you could use another type of engine management to accomplish it's role in that feature? Wishful thinking but I think it would be darn cool to get it working.

 

What is interesting to me is that the the Collins site states "Automatic Rear housing is not required however it is preferred, as the manual rear housing has two bolt holes in different positions, but it will work without those bolt holes." Which leads me to wonder how it works with the manual rear iron or if you simply have only 2 less bolts holding the bell-housing to the motor.

You would definitely still need a PPF as it supports more than just the transmission. The two rear holes on the PPF secure the transmission to the rear end while also supporting your differential casing. Right?

This thread looks promising. Given his last post was today and didn't say anything about the transmission going in or the PPF I don't know that it is all sorted yet. Will be subscribing to that one to follow the progress. Thanks for the link!

I'm under the impression it connects the transmission to the rear diff. However, if you have a diff brace like the Banzai or Rotary Performance unit, I'm not certain if the PPF is even relevant anymore. Someone else smarter might need to answer that question.

 

Common misconception.
The threads used for braces at both ends are not sufficient to support the transmission and differential and associated driveline shock.
They were only meant for chassis bracing across the DS tunnel. In combo with a PPF, it's probably fine. But without one...

Someone very recently demonstrated they were ripping sheet metal at these mounting points on an LS converted FD w/o ppf(IIRC).
YMMV, but if you have the option to keep your PPF then do it.

 

Not entirely sure what you mean by this. Can you elaborate? You're saying the PPF was intended to brace, and reduce flex, of the DS tunnel? So it's really a chassis brace; not a drive train brace?

 

This is very interesting because I have been trying to figure out what transmission I want to run for my car. I am with Skeese though...how is it compatible with the manual rear iron if it uses two less bolts?

 

Aftermarket diff and trans braces bolt to factory mount points. Those factory mount points exist for braces that cross the trans/driveshaft tunnel. You just remove those factory tunnel-braces and replace them with Banzai(for instance) trans and diff braces.

The mounting points used for this are not designed to support the entire driveline. In a stock 2 rotor FD, where you keep the PPF it's not a big deal because the PPF is still there doing it's job.
But, in setups where the stock PPF is no longer viable(20b/LS1/etc swaps) those factory mounting points are not sufficient to support the entire driveline. A problem exacerbated by high power and high abuse.

Check out some installed pics and you'll see what I'm talking about.

I should think to get the throttle blip working you'd have to go DBW

 

interesting. I already went with the T5 for my setup, mostly because frankly the gear ration in the 370z box are "meh" with the short 1st. At least its only a single overdrive.

 

You'd want to use the Sikii or Samberg brace, and transmission brace like the hinson design for LS swaps, and ideally with a plate on the inside as to not rip out the underbody metal.

BTW guys, there's a guy out there making adapter plates for the t56 that bolts right up to manual bell housing now, and allows starter clearance. All you'd need is rx7 type clutch with a custom 26 spline To me this is ideal, as after working on a reverse mounted starter auto bellhousing, its a PITA to get too the wiring/remove starter, and don't quote me on this, but I do no think the auto starter can be modified to 2kw like the manual with rx8 internals.

 

More info on this?

 

Yes...who is this person. I know Chip's motorsports isn't doing them anymore, I never saw a completed CPR kit, and I emailed addicted after reading a monsterbox post that they were now making one but I still haven't gotten a response there.

Resurrecting this string...

Anyone else try the 13B to Nissan transmission adapter plate?
