I have a 1996 Max w/ the tranny on the way out - I was talking to qute96 on AIM and he said that the 4th gen and 2k trans are exactly the same and there is no point to upgrade, and that it wouldn't make any difference? I am going SC'd soon and I have heard that the 5th gen tranny is stronger. Can anyone vouch for this, or is there info anywhere to compare these 2?

Thanks,
Chris

 

From what I've read, the 5th gen is slightly stronger...not sure if it's proven though.

Also, according to Dixit and others, your shifter will move a bit. On the 5th gen using a 4th gen tranny, it required bending the shift lever rearwards to keep it from hitting the front of the console. However, it should be great on the 4th gen. having the lever slightly closer to you, ie don't have to stretch as far to shift.

Also, if possible, get the 2001 AE LSD trans..

 

Yeah i heard that the LSD tranny, the 2k1 trans, is really nice. I dunno, there are alotta people using the 2k trans with no tranny death issues...i just dont wanna blow this transmission.

 

If you went AE, you'd need an AE drivers' side axle, so most don't go that route besides them being impossible to find.

Anyways, non-LSD 2K or 2K1 is a better choice then 4th gen trans. IMO.

 

just curious, why? There's a 2k1 AE I'm waiting to save some $$ for so are you saying that a phantom grip + 2k or 2k1 is better than a 2k+ vlsd (since quaifie is impossible to get now)?

 

i30 lsd for a 4th gen is also another option. PM slammed95 at Top Element Tuning for a price quote on lsd tranny

 

there's plenty of 4th gen se tranny's up here in Canada - they have the vlsd but isn't it something like 80/20 split, so not very effective? I'm assuming the 2k1 vlsd is "better" in the sense that it's closer to 50/50 along with the prevailing wisdom that the tranny overall is stronger than a 4th gen tranny.

 

No, just because they are newer and most likely have improvement over the 4th gens.. No, I wouldn't install a phantom grip even if you gave it to me.

You could always convert to a 6spd with HLSD. If SR20 gets around to putting the HLSD in his '04 6spd tranny and it works with the taller final drive, I'd rather go that route.

 

hahah I dont wanna go to a 6spd, i dont feel like pioneering anything quite yet, I'm a newb. at heart. I think I'll end up with the 2k trans w/ the ACT street strip clutch and a nice 9LBS of Boost...sounds good, eh?

 

9lbs huh....you might look into the Kaaz differential.

 

How much would one of those run for?Thanx!

 

What's the Kaaz differential? I didnt know 9lbs was alot - infact I thought it was pretty safe? I know any additional strain on the transmission will cause it to wear out faster, but do I really need to upgrade my differential too?

 

It's not to "beef" up the differential, it's to put power down to BOTH tires. Hell I get wheel hop and peg-leg burnouts and I've only got 180ish whp, so with 9lbs. you've got around 100whp more.

If I spent that kind of money on my setup and it was finished, I'd want to upgrade the diff to MAXimize the return.

Thanks for the info, whats the difference between the 2k1 LSD MT and that? I assume its that the 2k1 is VLSD?

 

You'll need to do some searching on the net on how viscous diffs work, I'm no expert.

The Kaaz is also viscous like the 2K1 AE, however it has multiple plates and they can be varied to make it a 1.5-way vs. 2-way or whatever that means. Shadow can tell you.

 

Jeeze...i'm getting over my head here. In the same week I am doing trasmission, clutch, supercharger, gauges, SAFC, Cartech and Walbro - might as well do the engine while i'm at it.

 

All yourself? That is alot.

I'd do them in phases, ie Walbro/Cartech/SAFC/Guages first. Then SC. Once you shake all the bugs out, do the tranny/clutch.

IMHO, you don't want to do too many changes at once, because if there is a hiccup, it's harder to figure out what is causing it.

 

yeah, do it in the order icey says.

i did my s/c first

and then guages

and then walbro.

whenever a prob happened, i was like wtf?

theres just so much to troubleshoot

maybe do the tranny first since it affects your daily driving.

the cartech wont affect daily unboosted driving either.

 

I am doing fine on my ACT HDMM clutch, but if I had to buy another one, I would get the clutchnet one that IanS has. Look for his threads to find out more info.

So the quiafe is the best thing to have? If so, I am glad I got one. :>
I would be willing to lose it though if I could do the 6 speed easily.

 

Quaife is best hands down, but the '04 6spds taller final drive with HLSD might be a hell of a combo for the less torquey VQ30.

 

5th Gens have Stronger 3rd gear (completely different part # compared to the 4G tranny)

Someone PM'd me this, and I would beleive it's true - can anyone verify it?

 

its true. if youre going to have the sc and a tranny, why dont you get hte gears cryoed?

 

Yeah I have heard that cryo treating makes the gears something like 30% stronger, but where do you go about getting this done?

Thanks,
Chris

 

you have to send out for it.

and i had the favorite on my old computer.

i think someone else has it
steve

 

Hmm if anyone else has it that would be awesome

 

just search for it on google.com. there are a few sites

 

We have a local cryo shop we use for our lsd's and other parts. But you would have to ship the parts here, a little inconvenient.

I will say it makes a huge difference though. We've never had a cryo treated part fail. Plus we once made the mistake of cryo treating a piece before machining it. Lost a couple of cutting bits doing that, it took forever to machine.

 

so perhaps a good idea then, in the absence of a Quaife, Kaaz or Cusco lsd easily available for a 4th gen, is a Phantom Grip that's been cryo-treated?

 

Hmm i dont really have the $$ now to go anniversary LSD, you still think its worth it to go with a low mileage (50K) 2000 tranmission?
