The difference between just fine and perfect is knowing what a fully programmable setup does vs a limited tuning solution. You could run a carb on a boosted 3.4 DOHC just fine too, and that would be special.
There were no limits at all worked great runs the same as any of the thousands of l67's. I grenade 2 transmissions in 3 weeks the middle week I took first place in a class of 75 drag racers I did something right.

I have nothing more to contribute to this thread, good luck.
I would love to have something OBD1 that can recognize boost, do speed density, and allow real time tuning. I didn't go that way because 6 years ago when I was planning all of this and buying parts, it was quite hard to find OBD1 tuning solutions and I wanted to run a 4T65e-HD (I even have a spare one sitting in the garage). Since then, it looks like everything in the OBD1 tuning world has moved forward a lot, but that transmission would have still been a problem.
The biggest limitation of OBD2 in my book is its inability to recognize and use boost to tune (not to mention the inability to do real time tuning on the vast majority of PCMs). There are custom OS's out there that allow SD tuning, but they are few and far between. The last I heard about the boosted L36's was that they could see boost if re-programmed for a 2 or 3 bar MAP sensor, but it also prevented them from idling properly as it reset their barometric pressure calculation as soon as they hit boost. I remember some custom L67/L36 code being attempted, but it was outside the realm of what HPTuners was capable of. As long as the transmission itself doesn't complicate the tuning with weird quirks of an OS never designed for a manual, it should be MUCH easier to tune a manual car on a dyno than an automatic.
Either way, I tend to greatly prefer standalones to any stock computer tuning solution for cars that are far from stock (near stock, I prefer tuning factory computers). The range of capabilities and inputs is much greater and you know exactly what your tune is going to do. With factory computers, I always worry that there are tables I can't see and edit that are going to mess with the tune when they shouldn't and cause lots of problems.
I'll have the clutch tomorrow and the transmission Thursday. I'll drop off the flywheel, crank/main studs, and head studs at the machine shop on Thursday also. It shouldn't be too long now.

yes! wish i had gone with the 3+
Ive talked to a few people and they suggest not going with spec. One of them had 2-3 spec grenade on him, and the other had one slip like crazy.
As far as I can tell, no one else makes a high performance clutch for the 284. I checked Comp, ACT, and Quartermaster with no luck. Rock Auto does list some factory replacement clutches starting at $275.
I have a SPEC stage 2 clutch in my S2000. Initially, it was super grabby. After a few thousand miles it broke in and is now pretty good. It's always been really noisy (rattling), but it has held over 440 whp and 360 ft-lbf.
I was looking for the same. High performance clutch for the 284. I found nothing, but then some friends on a different forum suggested Bully Clutch. www.bullyclutch.com Im going with their stage 3.

Hey shoot me a txt when you get a chance.
96 Z34 3.4 SC DOHC Getrag, 284 5sd manual transmission, stage 3spec clutch, 97 engine, 97 pcm, S3 intercooler 1 of 1 Roots SC LQ1 in the world 8.5 psi.
I'll report back on the SPEC after I get everything installed and running. Right now, the machine shop has it and the JY flywheel to get everything balanced. I'm missing the throwout/release bearing for the clutch. SPEC will be sending it once they get some new ones they have on order. Funnily enough, when I called them to report the missing parts today, someone else had called them about a Lumina clutch.
Clutchnet also makes high performance clutches.

Lol that was me pissed about my clutch slipping. They said tho having my 6 puck re puked would only be like 70$. But i realy think i have oil getting in some how maybe from the trans input seal. Hey they put your pressure plat together correctly that's good.
I have a Clutchnet clutch in my Fiero with a 3.4 Camaro engine in it. Had no problems with it and it was reasonably priced. It's a 6 puck ceramic with spring hub running in a Heavy Duty Pressure plate bought from Advance Auto Parts.
