ever thought of the 6sped swap???

 

not gonna happen. there will be way to many broken drive line parts if i do that.

 

and i have my megashift tranny controler so the car isn't a douche to drive, i jsut gotta put it in.

 

once you go proper automatic that shifts like it should and when it should you never go back.

Now that's thinking out of the boxer!:lol:

i recieved a mini spool! soon the buckaru will be 3 wheel drive !

 

anyone have a non lsd diff carrier ?

 

are they all the same offset ?

Parking lots are going to be a bit awkward, and maybe sharp right turns, but I wouldn't be surprised if road-course-ish handling improved.

 

The problem with diffs is they make it easy to spin the inside tire when you're accelerating out of a corner, or lock an inside tire as your braking into a corner. Welding the front diff on our Escort crap-can racer was a huge improvement. Welding the rear diff of an AWD car probably won't be as big of a deal, but I doubt it will hurt.

 

And like BAC said, launching should be delightful - if nothing breaks. :)

What is your logic of going with a spool? Seems to me streetability other than a straight line is now out the window. No rear diff=weird handling...

 

not nearly as bad as you think, the front of the car is still heavier so it will turn fine the rear tires will scrub as long as they are not to shitty they won't squeal like a pig.

 

since the car is awd cornering will be fine

Sounds good, I was just curious. I think it will be a bigger deal than you say but you probably have more experience than I do.

 

I grew up with Audis, mom had an 80 Quattro with the vacuum locker rear diff. I was young...tried a lot of stuff with the diff locked. It would auto un-lock over about 20mph for safety but if you kept power applied it couldn't mechanically unlock so you could mess around. Makes more than just parking lots sort of odd. Doesn't really matter which wheels are driven, we have diffs for a reason. I'm putting my values on you though, you might not care about handling!

also playing with rear sway bars can pretty much unload the inside rear wheel under heavy cornering.

 

and i think nascar runs locked differentials. from what i herd the inside tire is slightly smaller diameter.

Your build was impressive, I was thing to top you build to do a V8 & keep AWD. Rotate drive train 180deg. Just to be a little different:rolleyes::).

 

But in reality, the truck space is to short (center of the rear wheels to the end of the trunk) in both the LGT & BRZ. Still think the BRZ would make a nice mid-engine, AWD, two seat platform.

I'm suddenly having a desperate urge to do this with an LSX motor...

 

I went through this in heavy detail. It's almost impossible to keep the car AWD and do this without sacrificing handling and cutting the hood.

 

RWD is actually very easy, but fitting wide enough tires becomes a challenge.

Power, yes. Low end torque, no. Turbo spooling characteristics, again no. LSx has 50-60% more displacement than V6 counterpart, and roughly 130% more than EJ25. If folks wait a little while LSx VVT will go mainstream in the modified world.

 

The way forward with the LSx swap is to enter the suspension geometry dimensions into software of the same-ish name, then move the steering rack and tie rod ball joints-on-knuckles down, forward, back, in, out etc until (IF you're lucky) you find a solution that allows the suspension to work as intended with reasonable bump steer curve, while still allowing the LSx oil pan to clear. You would still need to lower the front drive train to clear the hood. All in all a LOT more complicated than Frankster's swap.

i was thinking about it .. maybe you could get away with a fabricated oil pan and dry sump and move the tranny back

The problem with that is the axle shaft angle, especially at the inside wheel when turning. You would need to go back ~6", maybe more. To accommodate the trans in the tunnel, you would thus also need to lower the front powertrain a few inches. So the inner axle joints would be offset perhaps 8" from the factory plane.

Then with a GTO oil pan which has a huge slot for steering rack immediately in front of the lower torque converter / flywheel, you would fit really well. Issue, again, is solely with the axles. Custom axles with Porsche CVs would perhaps work, but if you have to kill your turn radius or replace expensive axles all the time, it would be a nuisance to drive. Even then, can Porsche 930CVs handle 500wtq at (random guess: 22* offset)?

 

Maybe it is indeed the best way to handle the problem. Maybe some amount of it would be really good for the swap (only a few inches back, in conjunction with geometric repositioning of the steering ball joint points.

 

As you made clear to me, even if you get the car setup such that you can bolt in a LSx, you still have to pay for the LSx WITH all the powerband upgrades that justify it over a well-setup EJ25. That means turbo(s), and a LOT if supporting mods that get expensive, even if labor is cheap or free (DIY). Due the realistic cost for me, I personally am tabling it for at least a year. There are ways to make a stock EJ25 perform well on the street that are a hell of a lot easier than all this. But if you have massive amounts of money you don't mind making disappear, then I'm STILL convinced that with some interesting and questionable work-arounds, it'll bolt right in. If tomorrow I lost my motor AND heads to metal in oil, it would be a different story, maybe.

C6 Z06 came with a dry sump system from the factory, so you might be able to use those parts.

 

It's a $15000 motor, stock. My legacy is worth less than that, and is almost as fast.

 

There is something to be said for some of the wtq graphs people are posting of modestly modified LS3 setups. Comparing that n/a torque to even a VF40 LGT is laughable and inspiring.
