Well Chris just about has me talked into getting his FB shell and making a racecar out of that, considering it would be a LOT cheaper and it's a lot lighter than mine too.

So it just never ends.

I went to the shop that's doing my front fenders today and test fit one of them. It's gonna be awesome! That's not the bad part.

The bad part is when I got home, I got up into the driveway and took the car out of gear, disabled the alarm and opened the garage door, and tried to put the car back into gear...no luck. I tried forcing it into gear and it started moving the car and killed it. Yep, the clutch pedal no longer disengages the clutch plate. As I'm not leaking any fluid, I'm assuming the clutch fork is broken, which happens quite often on our cars. Either that or the throwout bearing is bad.

Also, my Synapse BOV now sounds like my old Tial BOV with too much air pressure for some reason. It sounds cool but it shouldn't sound the way it does now.

^Good question. LOL

So, this is interesting. I jacked the car up and took a look. The clutch fork seems to be fine, and so does the throwout bearing. However, together, they do not pull the plate back far enough. The throwout bearing popped right out of the plate. Then I hooked it back in and it stayed, then popped out again. So it does clip back in but it won't stay there for long. So it looks like I'll have to pull the tranny and take a closer look.

Frank, when are you getting back? LOL

sounds like your release cylinder is about to take a dump or you master.

edit: i read it again lol

so i think you stretch the crap out of those to hook thingys on the throw out bearing. happened to me once when i ran a 6 puck

Are you talking about the part on the bearing where the clutch fork goes through? The part the fork puts pressure on is pretty stout though. I thought it might be the same thing but they look like they're in good shape. The problem seems to be with the ring setup that the bearing hooks into on the inside of the plate, as much as I hate admitting that haha. I think I might just man up and drop the cash on a twin plate with my deployment money, but I need to fix this issue for the summer.

Almost everyone making real horsepower on an FD runs an Exedy Twin disc. Comes with a flywheel and is $1600:

Carbonetics makes good rear ends but I've heard their clutches aren't the best- definitely not up to Exedy's standards.

carbonetic lsds are one of the best out there but i would think their clutches are the same. that price for a twin plate isnt that bad at all.

But $1600 for a proven twin disc kit is an even better price ;)

So Zico and I pulled the tranny last night. The only thing I found messed up was a completely destroyed roller bearing/pilot bearing. I'm trying to figure out how that could keep it from disengaging but I guess it was. Everything else I've looked at looks just fine. In any case, I had already ordered a new/upgraded clutch fork, new throwout bearing (both from Malloy Mazda)...after I saw what was bad I ordered a new roller bearing and seal from Mazdatrix last night. I'm going to inspect the pressure plate closer to make sure it's good, and if the problem persists I may just get a new master cylinder. At that point pretty much everything else will have been replaced haha.

Also, I don't remember if I posted about this, but a while back I had run the engine with the turbo and manifold off, and confirmed that it was indeed the turbo that was leaking oil. I could even see some oil on the turbo itself where it leaked out between the CHRA and turbine housing. I saw some turbos on RCC that were for sale, and I talked to one of the guys and he was able to figure out what CHRA I needed and after I paid $1145 for it the other day, (I know, YIKES) he sent me the CHRA balanced with wheels and all, so all I'll need to do is put my housings on and drop the turbo and manifold back in. So hopefully no smokey and all powa!

I also installed the new EGT sensor and it's working, so no more problems there either!

It's finally coming together, right as I'm about to leave again haha.

I really would have loaned you my perfectly good 3582R :)


EDITZ;

I do not really care for the Exedy twin-disc, they are heavy and break too often IMHO, and they are $$. For not much more, you can get an OS Giken or Tilton setup and forget about having issues.

I have had a pilot bearing fail and try and seize to the input shaft, which in effect "welds" the input shaft to the flywheel, which means the clutch does nothing to dis-engage the engine from the trans. Make sure you grease it when you install it, I use Redline CV-2 but any good heavy, high temp grease should be fine. Also, no need to order one from Mazdatrix, most parts stores will get them for you within a few hours (they have to get them from whatever warehouse they use) and they are usually the same NTK/Timken that you will get from Mazda etc. I keep them in stock and in my spares box for the race cars.
1986 Turbo FC race car, S6 13b, GOOPY Apex seals etc, GT35R, AEM EMS, lots more good stuff

Well like I said before, I'm not sure about borrowing a turbo LOL. I was going to lend a tranny to someone in NC one time so he could race one weekend. But to me, a turbo is a completely different story haha.

I might still get a twin plate clutch while I'm deployed, but I'm incurring more and more expenses every day and I'm not sure if I'll have enough deployment money to make the rounds. If I can figure out this clutch and make it work, maybe it will hold at least until my next deployment, most likely next year haha.

I didn't know parts stores could get pilot bearings. I already ordered it from Mazdatrix the other night though. But maybe I'll get another one for a spare haha. I did grease it this last time but maybe I didn't use enough or maybe I used the wrong kind, not sure. Actually, I take that back. I keep forgetting I replaced the engine since last replacing the clutch, and used a different e-shaft, therefore I doubt if I greased this one when I put the engine in, and I'm not even sure I changed it from when I had this engine in back in 07. I'm feeling much more confident that this problem will be resolved. Thanks Don!
