Opinions needed:ZSpeed HD CSC or Z1 Motorsports Slave Delete

jae35 · 01-14-2015, 11:10 AM

Hey guys i'm just looking to pick your brains a bit here as i'm in a bind as to what to order. Has there been any reports of people blowing out the HD slave cylinder or should I just delete the thing and forget about? Looking for unbiased opinions. If you do have the Z1 delete did you replace your master at the time of install as well?

Thanks in advance

There have been failures to the HD CSC from ZSpeed but almost all of them are linked to having a shitty SPEC clutch. If you aren't running a SPEC clutch then you are probably going to be fine. That being said there is some romance to deleting the thing completely. I haven't heard enough feedback on the Z1s delete kit to base an opinion.

Try to pm Osiris I think he is running on CSC delete

I believe the Z1 kit is basically just how the 350z cars were with an adapter to fit it to our transmission.
I saw one of the elimination kits early on (a non-Z1 version) and it was all Nissan OEM parts minus 2 pieces.

The 350Z didn't have a CSC?

I was under the impression that the CSC failures have been common since the 350/G35 days

They might also, I just remember someone mentioning that the elimination kits were mostly OEM parts and probably off a 350z design, maybe it was a different Nissan car they were thinking of.

Hmmm...maybe the DE didn't have one, but I was almost positive the HR version shared our troubles.

Could be wrong, wouldn't be the first time

07-08 350Z and 07-08 G35 Have the same clutch and slave set-up as the 370/G37 cars.
Only the early DE models 03-06 Z/G had an external type slave, those early cars were the ones with trans syncro issues IMO related to a improper/incomplete release of the clutch, In 03-04 they had a weak clutch fork which flexed a lot causing poor clutch release leading to the syncro issues.

This. Joe at Zspeed had told me that pretty much the only failures he's seen are linked to SPEC clutches.

DOOMMONKEY777 · 01-19-2015, 12:26 PM

Well i have a twin disk spec ss clutch, and ye they used too many umm lets call it pressure metal thiny that presses the clutch to the flywheel, i mean i counted 4 on each stack, which is tooo many in my opinion i remember removing 1 form each stack and that made the clutch weaker about 25%=less stress on the csc n cmc, although i have a stock engine it still grabs nice.

The Z1 delete option is very nice. Wish it would of been out a lot sooner.

The only issues I've seen with the Zspeed HD were due to a spec clutch or incorrect installation. It is generally recommended to replace the MC whenever you replace the CSC.

Chuck33079 · 01-20-2015, 07:43 AM

I'm running the RPS clutch / Tilton setup that Specialty Z sells, but if I had to do it again I'd go with the Z1 delete. The fact that, if anything fails again, the parts are outside the transmission makes it really attractive.
