Mind if I ask what clutch you are using on your sr? I'll be using an ORC 409D super single. George said someone has used his plate before with that clutch, but not with a internal slave trans. I got the slave spacer and everything so I'm hoping it all works out. Still trying to find a shifter.

dude i have a spare shifter i accidentally ordered 2 so please hit me up for it. ill give you a good price.

and im using my old SR clutch, Spec stage 3, its barely a year old and has plenty of life.

[ultimateirving]

She is installed. Was a little bit of a pain getting the motor mounts to line up and the trans doesn't sit level until I notch the shifter hole. It's barely hitting. Also did I mention previously I had to grind down the Bellhousing where the elbow touches the would-be starter location on the stock z

[crewchief05]

Who would everyone who has actually done this swap recommend to get their kit from? George or Collins? No slamming just personal experience.

[ultimateirving]

George is local for me and his kit went together flawlessly. Plus it came with all the hardware you need for the transmission in the mount

S13 or S14?

S13/s13 sr with oem replacement motor mounts. Other than the shifter hole, nothing on the body needed to be modified.

nice ultimate, i forgot to mention that i did have to also grind that area down on my transmission to make room for the bottom mount turbo elbow

the collins kit works greak but Brett is a bit slow making the parts and sending it out the issue i had with the throw out bearing carrier was not bretts fault apparently the 05+ tranny has a shorter pivot ball then the 03-04 trannies and if i would have used the 03-04 pivot ball i would not have had the issue. but the 6 speed runs super smooth even with the 6 puck act extreme clutch its not an unbearable engagement like my brothers clutchmasters clutch is and the gears fly so fast! the car feels like a beast and i have less power then i did before i took the engine out because now im running 10psi because of the untuned AEM

i love it and you will too! totally worth the money heck i spent more on my wheels then i did on the 6 speed swap

also the collins transmission crossmember lets me use the regular sr/ka transmission mount which i was happy about because ive had Nismo mounts for about 5 years now and im super happy with them and they still look new

[crewchief05]

Yea battosaii930 I actually called and pointed them to your thread. He was pretty bumbed to see you didnt use the throw out bearing carrier. I agree the collins kit is awesome but the turn around time seems leghthy. Do you have any chattering coming from the clutch engagement or anything?

[TheRealSy90]

I also reccomend George's "Maverick Motorsports" kit just because of the ease of install. No issues. Plus he even made the new parts for us guys that wanted to use the revised 08+ HR trans.

[battosaii930]

yes i do get some chattering but i really dont hear it much its not too loud with the shifter hole sealed up but the car does shift super smooth

[crewchief05]

What about you TheRealSy90.since you used George's setup did you have any chattering?

His trans isn't in the car yet. I'm very close to driving so I'll let you know what kind of chattering I experience with
George's kit. I'm also using a spec stage 3 sr clutch.

[crewchief05]

Im sending mine off this week. But for sure keep us all updqted. Ill be using a spec stage 2 as well.

[battosaii930]

from what i heard the chattering is from using a lightlweight flywheel and has nothing to do with whos transmission swap kit you use but im not worried at all ive seen much much much worse chattering on an evo

[ill.]

Hmmmm. Just taken the car for a long drive.

It seems I am getting some chattering off throttle. Goes away the moment you put the clutch in while rolling. Anybody getting this?

Had it up on stands and it seems to be backlash resonating through the 1 piece driveshaft.

[battosaii930]

That's exactly the chatter I get I don't think its a big deal though

[ill.]

Yeah. I just turn the radio up haha.

My diff has huge amounts of backlash, but I'm going to a GTR rear end setup sooner rather than later so that should rule that out as the cause.

[battosaii930]

no movement in my rear end and my j30 vlsd is quite healthy since i dont drift i just do the occasional auto-x and spirited driving

[Black240Ct]

Yup my trans is very loud compared to an sr and vibrates more. I think it's the nature of the transmission. 350z guys have been crying about it for ever

[TheRealSy90]

It just makes everything more racecar. Tell people you have an osgiken dogbox with h-pattern shifter conversion.

[crewchief05]

If only it were true haha. Btw sending my bellhousing, shift linkage, shift bracket today....WINNING! (Going withGeorge's kit)

Woot woot, Soon you shall be driving again!


Edited for update, new driveshaft arrived. Pretty much all my harness is reconnected and I just need to install my radiator and intercooler piping. Then fill with fluids and it's time to drive.

[crewchief05]

Did you go 1 pc aluminum or steel?

[TheRealSy90]

Sinced i've already had a 1pc aluminum with my sr for 3 years, i figured I would just stay aluminum with the z trans, although people have been telling me to go back to steel because of the "rotating mass". But I like the aluminum shaft.

Steel driveshaft $250 made here at a local shop.

Drove car last night and it was awesome, need to bleed clutch better and fix a coolant leak then I can rip on it.

[loucal]

Chiming in here as well. Putting most of this together this weekend. Do you guys have reverse lights? I know thats random but i figured I'd ask.

2005 CD009 Trans 51k miles
Collins Adapter
Collins Throwout bearing Carrier
Collins Tans Cross member
Fidanza Flyhweel
ACT 6Puck Clutch.

Still trying to decide how to get the speedo to work. I have J30 diff so i suppose i can use the Dakota box.

Will keep you all updated as well.

This is an excellent thread btw not too many out there about this setup.

-Lou

[ultimateirving]

Lou I chopped my reverse light clip off the stock sr trans. And I'm gonna see if I can wire it to connect with the Z reverse sensor with some spade clips or something then make sure the harness can reach the factory plug.

This is all theory so I don't even know if the signals will interface

[TheRealSy90]

Should just be an ON-OFF sensor basicaly, completing the circuit when in reverse to throw the lights on.

[Lidgsa]

version will work also?

[ultimateirving]

Drove to work today. Clutch chatter is definitely more noticeable. Also in getting a fair amount of vibration on the freeway around 2500-3k rpms. I don't think it's bad just a side effect of the large trans in a tight tunnel
