I just swapped in an IX GSR engine on my 2003 GSR w/ a competition twin disk clutch & flywheel that was meant for the IX motor (if that even matters). I just got my transmission built from Shep Trans and I'm using my 2003 starter.

When I start my car I hear this loud clanking noise. It does it when I crank or when the motor runs. It's so loud that I am afraid to start the car again. What did I do wrong? Is there a specific way the twin plates need to be in there? As soon as I blurp the starter I hear the noise. It really sounds like the twin plates are making noise. Is there a specific way to install these clutch disks or clutch?

I did installation in the correct sequence torquing in pattern and at 3 torque stages w/ lock tight. I staggered the disks like someone had mentioned online, but I didn't see any other special instructions. I mean this noise is ridiculously loud and it is for sure connected to the starter/clutch/flywheel.

I was also thinking, is there a difference between the 2003 and 2006 starter or flywheel? Maybe the starter isn't retracting, the teeth count or size isn't the same? It's really f***ing loud and sounds like some loose metal plates banging around in there.

 

Tooth broke off the ring gear? Highly unlikely that would happen without anyone noticing. There's no difference between 8/9/X clutches and from what I see there isn't a difference between 8/9 starters. When I hear that noise on bikes that come into the shop it's usually either the clutch ring gear (not so common) or the starter gear and one of them is missing teeth from people trying to crank it over for long periods of time or a sloppy install (someone dropped the clutch) Subscribed I'd like to know your problem since I'll be installing a Comp clutch here soon.

 

Yes the discs will only work in there one way as they telescope into each other. you can possibly try to pull the starter out and bump start it and see if the problem is still there if you think it is something to do with the starter.

 

I just built the entire motor so I need to break the car in. Bump starting is not an option as I am in a garage and the only thing is down hill.. I don't want to try to get my car up hill and or work on the street.

I inspected the clutch and flywheel before install and there was no damage.

 

Are you sure what your hearing isn't just clutch chatter? Unsprung twin/triple disc clutches tend to sound like silverware being shaken in a drawer when you start them/when the clutch pedal is depressed.

 

Totally unrelated to the issue but how does it look under the hood with that weird bracket thing? I wanted to try a comp clutch out but I seen the directions and I don't like how complicated the install is vs an Exedy twin/triple. Not to mention that crazy metal bracket deal.

 

Is there any way you could post a video we could listen to? That would help a lot. "A loud noise" doesn't really help us help you. I know that when I search for a starter that the IX starter is significantly more expensive, which led me to believe they are different. In what way I don't know. But I've had the comp twin in my car for about two years now. They do make a considerable amount of noise with the clutch pedal depressed and when engaging the clutch. Have you ever heard any other twin disc clutches?

 

If IX starters were different, wouldn't the flywheel be different between VIII's/IX's? Or the way the transmission mounted etc?

I definitely feel like its the clutch chatter the OP is hearing. I had someone who put a twin in their car for the first time the other day call me after they started it and told me their motor was knocking

 

The flywheels are the same for VIII and IX so it must be something else in the design of the starter. Who knows...IX's have more expensive parts than VIII's in some cases.

wow...if your gonna intall an expensive clutch in your car I would hope you would do some research beforehand.

 

I think you're driving the wrong car, shouldn't you be driving a VW and posting on the vortex? Just for you, as you seem to be the typical troll, here is my build so you have a true idea that this wasn't just a simple "clutch" install. https://www.evolutionm.net/forums/ev...ld-thread.html I built this car myself from the ground up and this was the first time I've ever touched a twin disk. Unlike you who pays people to do all your work. There really isn't much information on the competition twin. If I would have installed the clutch without looking online, I would not have had any problems. It was false information that lead me to this mishap. People make mistakes, it happens. When you work on your own **** and don't pay someone else, that's when you have the right to act like you know what you're talking, but you still don't have to be a dick about it. Douche.

 

I'll try to remember to get you pics after I put my transmission back in.

Honestly it's really not that bad. Seriously.. I don't know what the instructions look like as I don't have any, other than the *.pdf they have on their website. If you have questions let me know, I'm sure I can help. The best part about this setup is you get ride of the annoying stock TOB. That is the main reason why I wanted this clutch kit in the first place.

 

In this picture the floater plate is installed incorrectly and this will definitively cause an issue.

 

Yes that is correct. I properly re stacked the plates last night. If you look at the floater plate there are points that protrude outwards. Each "U" point should go around the mount/pillar of the pressure plate.

 

sweet! did you have a chance to get it back together yet?

 

Not yet. Tonight I will put the transmission and clutch back in. Looking foward to breaking in my engine tomorrow. Hopefully there wont be any bugs.
