Supercar Engineering Crazy car handling pack: First impressions

I'm pretty sure it's not required since what....only 3 x of them have ever been broken? but if it does go it takes out thousands of dollars worth of gear and labor so I figured why not

And it's Shiney!

Jacks sells all the diffs etc. I'm in discussion with him at the moment. Looking at converting my 5 speed to a USDM 6 speed and having the bell housing braced, billet end cap, all 3 diff upgrades and the 300m shaft [300m comes with the sce centre diff]. However he said the billet end cap is NOT required for my target [600AWHP]. Does anyone have any input on this?

I see no reason what so ever to want to convert a 5 speed to a 6 speed except for the overdrive to achieve better gas mileage. Stainless or billet transfer case, 300m output shaft, and bellhousing brace and you're set!

I don't trust anyone in Australia to rebuilt one of these boxes to handle a minimum 600awhp so i'm looking at getting Jacks to do it over there. But it's cheaper to aquire a box overthere and rebuild then ship back here. And since you can buy a new 6 speed box at the moment for dirt cheap it made sense to do it that way. Also I want the taller 6th gear. My understanding of the USDM 6 speed is that the first 5 gears are fairly similar to the 5 speed and the 6th is taller for better highway cruising and mileage. But I guess in the long run the SS transfer case and 300m shafter would be cheaper. But I also want to upgrade all 3 diffs.

I wonder what % of Gearboxes out there are 5 speed Vs 6 speed.

In that case, that makes sense. I would LOVE a brand new 6 speed. I've been driving a 5 speed version for a few years now and I drove my first 6 speed the other day. I wasn't the biggest fan of the gearing, but it would be ok after some getting used to I think. And if you want the taller gear, then go for it.

Sounds pretty much how I wanted my VR-4 to feel. I wish I had the spare cash to just spend on the diffs. Would have taken me eons to save up

The 6 speed gearing was similar to the 5 speed for the first five gears, except each gear was shorter. 6th gear was a bit longer than the 5th gear in the 5 speeds.

I wish I had the money to put into my drivetrain like that. Haha I feel like I'm spoiling it by running all Redline fluids

[MR2]

haha, yeahh that stuff is pretty cheap over there though, here in aus that stuff is like double the price (and then some)

[green-lantern]

I try not to talk about stuff that's a while off...as the engine is atleast a year off (I have some debt to get rid of) in the long term plans however I have:


a pair of 6g75 Mivec heads currently being modified (by Oohnoo) to fit on a 6g74 block
6g74 block + 6g75 crank are sitting in my garage, eventually to be bore'd out to 95mm (should be around the 3.8L mark if all goes well) may need to grab one of Rays cranks as the 75 one looks a bit flexy!
on the turbo side of things I bought a 3sx turbo kit + terminators before working out that I could have afforded a DR Kit...oh well, I hear that Comp Turbo can do billet compressors and hopefully we can get some TiAL Turbines and bring them up to spec..
all in all I'm not sure at what point i'll be happy with it, still trying to get the brakes just right...believe I'm close on that one though! also not even sure what I'm going to get into(racing or driving wise)...just kinda plodding along and seeing how each mod feels

I know it's weird but I just like stuffing around with it

I would go with Rays crank. If you are putting out the cash I think you would be making a big mistake not getting it.
