A568 Shifting Mods - Crash Box

[Reaper1]

It depends on what "big money" is. I would STILL consider it even if it were $300/gear (meaning gear and slider).

I've been thinking on how to have new synchro dog teeth machined and installed anyways since the first mention that there was somebody doing it or the old 4-speed Hemi transmissions. Honestly, it really shouldn't be THAT difficult to do. To make a slider an EDM machine would be needed, but I think that would be the worst of it.

I'd machine the face teeth for the gear. Machine the dog teeth of the gear so that the new face is a press fit. Press it on and then TIG weld the ring to the gear (this would require preheating). Let it cool and then check the critical tolerances, mainly the inner diameter of the gear where it rides on the shaft. If it needs truing, do that machine work. Then, I'd surface harden the new face dogs and do stress relief on the weld. Done!

The slider, if made from scratch, would obviously be harder to do. You *could* use a similar method to make the face slider out of the original one and that might save some effort there.

I wish I had the kind of machinery at my disposal to do this. I'm very certain this would work!

if you are going to go to all that trouble, just machine/weld up a custom bellhousing and use a quaife sequential box.

Good luck on D-day, Very interested in your results!

+ infiniti!

Pretty much EVERYONE rowing is waiting to see what happens!



So, are you done yet?
























How about now?

I've thought about and drempt about doing that as well. Honestly, if I'm going through THAT much effort already, RWD here I come!

The car went together yesterday but I have a no start I modified the computer for sequential injection and COP so it was a big unkown since I also had to build a circuit for the cam and get it all synced up. Tonight I will be working hard to get it started and if I do then I should be good for the races. If it doesn't happen I'm still in good shape to hit a Friday night street legal when I can get it sorted out.

[BadAssPerformance]

Bummer, good luck man! *fingers crossed*

[Aries_Turbo]

you use the circuits on unas page? theyll work on the 2.4 cam and crank sensors just fine.

This tells me they have too much money making work to bother with onesy-twosies, unless someone wants to pay them a crazy amount of money (the quoted $5000). Basically they don't want to do it and so you'd have to make them an offer they can't refuse, which in all likelihood means you could have them made from scratch by a "normal" machine shop for much less... Or find another specialty shop that isn't as busy!

I would rather keep the clutch light and avoid things like this.

I did also remove 4 1/2lbs from the rotating end by way of a lightened flywheel and un-sprung hub.

As for the liberty stuff, I came across them a while ago so my plan was to take the 523 gears from the 3.85 transmission I stole the FD from and start experimenting with them to see what kind of filler, pre-heat, post cool ect. would work well. I like the idea of a dogged tranny with helical gears. I'm definitely not making any guarantees to when I'll get to that one though.

Well the car runs now so that's a good thing. Unless something drastic happens on Sat. I should be good to race on Sun. My plan is to race the day like I would normally shift since there is a decent amount of $$ on the line. This will at least show if they can hold up to the power under "normal" hard shift conditions. Assuming that goes well I will look at hitting up a street legal where I have nothing to lose and can see how it WOT shifts. I find the one of the biggest challenges is mentally not lifting my right foot which is usually followed by the challenge of the synchros behaving like crap. Hopefully that will be all but a past memory.

How's it street drive?

I don't know. It revs really nice I'll take out on Sat for a bit to make sure the tune hasn't changed much.

PS, I don't really like the new I don't feel it expresses my true emotions like the old one did.

You got the new crash box gears in right?

I think he's just reving it up and down in his garage right now. Unlike the both of us who would instantly take it for a ride the moment it's running and not a second later, DJ has.........Patience , kind of like when your first in love. He can wait for Saturdays ride while all along he savours the anticipation of what's to come!

[turboshad]

Or I was missing the front wheels, it needs an alignment and it was 10 at night while I still had an oil change to do and button up the wiring. Pre-natal class tonight so Sat it will be. I also don't have a dash so I will bend up a quick piece of aluminum to hold the cluster and some gauges so if I do get pulled over I have a standing chance. But as far as I can tell the gears haven't fallen out of the tranny yet.

Any updates?! It's now Sunday EST!

[turboshad]

No updates that anyone wants to hear. The car is missing at any RPM over 2000 and I've run out of time to figure it out. I'm sure it's something simple but I won't be making the race. I'm pretty discouraged as I put in over 60 hrs in the last two weeks to make the event. As soon as I get it figured out I will be out to the street legals.

[Shadow]

Keep at'er bro, we're All rooting for you!

[Reeves]

Dang......

Got it fixed yet?

Dang......

Got it fixed yet?

Oddly enough yes. With a fresh look it took me about 1/2hr to figure it out. Turns out the lean AFRs I thought were from the misfire were actually the cause of the misfire. Added a little fuel and what do you know....who woulda thunk? I think I was just too tired to think straight. I'm pretty busy this week so I won't have any time for it but it will be driven next week for sure and if the weather holds then maybe to the races on the Friday.
