Need some advice/options on a few trainmisson options. I was looking into getting a Gforce tranny but after speaking to them there are a few mods that i would need todo that I'am not willing to do. like cut up the car.so I have been doing some light research and I'am looking into these options just want to know what the community thinks. power goal would be 600-900hp ( vvl head swap) car would be a weekend warror (drag) but used on a daily. here is what im looking at

1.nismo 6speed for an s13 sr20det
2.300zx trans

opinions please

T56 or TR6060

/thread

Also, if you aren't willing to cut up the car, you are going to be replacing transmissions a lot if you are hard launching. Do the leg work once and get the right transmission. Look at the Mazworx drag car or check out the drag racing thread on here.

The Z32 trans are cheap and plenty. Also they support 800 HP on a vet.

While I would agree with you 10 years ago, they are aging and getting more a little more sparse.

The NA and turbo trans are the same sans bell housing . The NA would have lived a very very easy life behind a 30 year old NA V6 as most were bought to just cruise around

However you are correct in that the youngest one is over a decade old. You can find rebuilt ones however

I have been reading up on a few different options. maybe what I should say is what works the best. with gforce i would I also need to change the drive shaft and I believe I would have issues with the speedo. seems as if the z32 would be the most cost-efficient. gears are still very close to the sr from what I've read. close gear ratio seemed to have great benefits. after seeing a couple of sr run great times. I'm going to check out the TRC thread and see whats up.

It fits so well in an S14:

Here is its nesting place:

I think the small casing box will die fairly soon.
the z32/rb25 box will take it for a while, you will probably still end up stripping 3rd/find it grinds when trying to shift at high RPM.
350z might be good option if you can pick a decent late spec box up for a sensible price.

t56 sounds like a good option. use an auto belhousing and make an adapter.

thanks, was just reaching out to mazworx looking into the cd009. just doing the math on cost, drive shaft, cutting the housing etc etc.

I have both the Mazworx bell housing setup with driveshaft (CD009) and the adapter plate (Z32 5 speed)

The bell housing is worth its weight in gold when retrofitting to a S chassis. You will still have to get the bell housing machined, a driveshaft, tranny mount/bracket, and bell housing adapter, shifter, etc. But the idea of everything just fitting, not have to drop the subframe to do clutch jobs, etc, is worth the extra few hundred in difference between the two.

this is one the reason why im looking into it. i see they have a complete kit. hopefully, i get a chance to speak to someone tomorrow and see what they would charge to do the complete job. they are already going be doing my bottom end and head. I hope everything works out great. spending a lot of money there. haven't spent that much on the car since XAT racing. now you have the CD009 setup? how much power are you pushing? what and the pros and cons.
thank you for all the info.

RalliartRsX · 12-25-2017, 09:11 PM

Not sure what my final power goal is. 500WHP is my target. Anything else is gravy......or if I am feeling a little adventurous when on the dyno.

TheRealSy90 · 12-26-2017, 07:56 AM

There is no "machining" required when using the Mazworx SR/Z33 trans bellhousing. Everything can be done with a sawzall for the bellhousing, and a cutoff wheel for the input shaft. Everything with the kit works great but I'd recommend a better shifter relocation from GkTech or Serial9 for example.

I second this, running Mazworx bellhousing with GKTech shifter IG is DustinClement if you want to see it I think I posted some cut pictures and install shots/videos
