I'm new to the whole v8 LS1 world. Could someone help direct me in the right direction... I am doing a LS swap into my 240sx... I Bought an 04 CTSV T56 trans because the deal was good... Researching more into it, it probably wasn't the best choice.

My motor setup is a 5.3 L33 with all LS stuff on it.

Anyways I have a stock LS1 flywheel and a LS1 ACT clutch. Was about to order my GM performance slave for LS1. But I want to make sure that I will be getting the correct one. Also I read someplace that I would need a spacer for the slave to eliminate the stock CTSV dual mass flywheel??

Someone that knows a little more about this could you please help me out with this.

Just trying to get all of the pieces to get my motor in, I have searched and searched and cannot find any answers.

Also... will a normal ls1 starter work on this?

Any help is greatly appreciated

I have a 2004 CTS-V and it has the dual mass flywheel and CTS-V T56. I am installing an LS1 flywheel, Centerforce 12" DFX clutch and an LS7 slave cylinder. I also have the Katech spacer but I am unsure if I will need it. From what I am told, I will not need to use the spacer. I am currently in the process of the install. I just pulled the tranny last night and I should have this info that you need later tonight or tomorrow.

You are going to need the pilot bearing that is specific for use with a short input shaft. It is a large diameter bearing (about 2.5")) and sits on the end of the crank. The standard pilot sits further in the crank and is smaller (about 1.5"?)

check out this thread. It shows the specific pilot bearing that you will need. It also shows the (traditional style) LS1 pilot bearing

Solid information. Thank you!! Im planning on going ahead and buying a slave and a LS6 pilot bearing... Just trying to determine if I should buy the CTSV specific one or the normal ls1 GM performance slave. Then getting it all together and determining if I will be needing to put a spacer in.... Definitely let me know how yours turns out!!

You want to use the C6 LS7 slave.

Also, I would imagine that the trans is a pretty tight fit in that car so I would go with a remote bleeder for the slave. You can get one from LAPD thats a bolt on

Yeah I got a remote bleeder kit with my Sikky swap kit. I had to beat my trans tunnel in to fit the trans haha.

Ok so LS7 slave cylinder, not the CTSV one?? Or the standard LS1 GM performance slave?? with running a stock LS1 flywheel and a ACT 6 puck clutch.

You can use the CTS-V slave cylinder but you will need the KATECH spacer. The LS7 C6 slave does not require the spacer.

The CTS-V slave with the spacer is the exact same height as the LS7 C6 slave.

I did not use my spacer. If you are going to use the CTS-V slave and you want it I only ask what I paid for it which was $35.

I do not know the height of the LS1 slave or the compressed height.

CTS-V slave on the left, C6 LS7 slave on the right.


CTS-V slave with Katech spacer on the left, C6 LS7 slave on the right.


CTS-V slave on the bottom, C6 LS7 slave on the top


The pic below shows the line from the C6 LS7 slave cylinder before I modified it. (YOU CANT USE THE CTS-V LINE BECAUSE IT CONNECTS TO THE SLAVE DIFFERENTLY) *look at the pic above for reference*


The pic below shows how I bent the line to fit through the front cover opening. Also notice that I swapped the bleeder line.

you can not use the LS1 slave. As noted above it would be the CTS-V slave + spacer or the LS7 corvette slave. Be prepared to notch or clearance for the lines where they exit the trans though, you might be able to bend them around just be careful.

When you buy the "LS6" pilot bearing make sure it's for the Cadillac, or or the C6 corvettes. LS6 corvettes used the smaller pilot that is not what you need.

If you need help let me know. If you need parts I'd be glad to help you out there too and make sure to get you the right ones, we keep this stuff in stock.

I used my LS1 F-body flywheel and a Centerforce 12" DFX clutch. These components were in my 98 LS1 Camaro.

After I installed the clutch and the bellhousing, I measured from the bellhousing face to the fingers of the clutch, then on the trans I measured from the face of the trans to the compressed height of the slave and the measurements were identical.

bwag, are you using the CTS-V shifter ?

bwag

Thank you guys a ton for all of this information it has been exactly what I needed to feel more confident with doing this!!

I think I am going to go ahead and use the CTS-V slave, because the guy I got the trans from still has it and said he will give it to me. I'd be interested in getting the spacer from you to make it all work right.

And I will get the proper LS6 pilot bearing from scoggin dickey

This is the master cylinder/ remote bleeder kit I have hopefully it all works with the ctsv slave.

Yes I am using the ctsv shifter, it has already been modified for fit into s chassis

Thanks again for this help guys!!

The SIKKY kit you have will not work with the CTS-V slave because the way the line from the master connects to the slave is a male / female connection. The CTS-V slave uses a screw in style. Take a look at my pic above.

bwag, check out this thread as well. It contains a lot of good info for tightening up the sloppy V shifter setup. I just did these mods as well and it made a BIG difference!!!

Boo... Maybe I can call and get them to send me the correct stuff

Would it work with the LS7 slave?

I will check out that thread as well, I have heard stock ctsv shifter is a sloppy mess.

Yes, the SIKKY kit will work with the LS7 slave.

bwag

Then I guess I should just go with that so I can get this together faster than waiting on Sikky to resend parts if they even could. Less of a headache I suppose. Plus a new Slave is probably better than whatever one was in this trans before.

I am having trouble locating where to buy a LS7 slave though.

I can't remember where I found them new but I got one with a few hundred miles on it. I think new they are around $180

bwag

Awesome thanks I have a friend at a local dealership, Just needed to get him a part #.

Also any chance you guys would know the part number on the correct pilot bearing I would be needing??

I do not. Mine was in perfect shape
