I've heard from a few people that apparently a rear V2 subframe could swap into a V1. Now, i'm kind of skeptical about this so that's why i'm asking.

I have my shop looking into other rear swaps right now...vs the 8.8 and 9" currently offered. GM Parts.

I'd have to assume that'd be a good amount of work, especially considering the gas tank location is directly under the rear seat, and right where the cradle is.

A shop that could fab that could probably piece together a proven 8.8 kit with strong axles pretty easily. If it was a 'bolt-on' solution that'd be pretty sweet with the ever present availability of crashed V2 parts.

V2 sub-frame, It should have all the same body mounting points.

^^^ Yea but will it bolt in? Some of us will probably go fuel cell at some point so it may not matter. but some might not. I'm sure its a can of worms that someone has already opened. I recall a V on ebay and CL a while back with a V2 rear swapped I think. The ebay listing is gone though so unless the previous owner is on here we have no way to verify the process.

I've read you have to swap the V2 gas tank in since the V1 gas tank will interfere with the V2 cradle install. The V2 has different fuel pump/lines or something to that effect, so those need fabbed as well.

yeah i've heard you have to use the v2 tank as well. i'm also pretty sure i heard the words "direct swap" but that's why i started this thread haha

Seems to me like wayyyy......too much of a PITA for a rear end that is not all that strong as to what you could replace it with for approx the same $, not to mention the hassle.

does the V2 rear end use the same spline axles as the V1...

I first hand have seen those v2s run 9s at 140 at like 4400lbs on stock years.

What could you replace it with that is that strong? The alum 8.8s will and have broke with a lot less power.

I have also seen the V2 rear ends withstand lots of power and put down some pretty fast et's

Are you sure those rears were stock? CV's etc? http://www.cadillacforums.com/forums...torque-hp.html

Not a lot of V1 guys running that high of HP yet, but let me know when you find one that has broke his 8.8.

Seems to me there is a whole lot of things do to do replace the cradle (brakes, hubs, sways, fuel tank, just to name some) where as the 8.8 is a bolt in replacement and the 9" is almost the same. Not to mention the easy of swapping gears and availability of parts for the 8.8. I don't know much about the V2 rear but....I know that if you saw a V2 running 9's it had a built trans and I doubt they stopped there.

2500$ + Hassle of install or 4,000$ and go. Just my opinion.

What about swapping all v2 stuff onto v1 cradle instead?..

If the v2 axles have the same spline count and same length as v1 axles, then maybe all youd have to do is weld in the new mounting points for the v2 diff on the v1 cradle, then keep the stock v1 outer CV's and slide the v2 axles in and bolt up the v2 diff to the new mounting points.. No need to replace or mess with the gas tank or anything else for clearence.

I saw the add on here of the v1 with the v2 complete cradle swap. I dont know whos car it is and he doesnt go into detail on how he pulled it off.

V2 diffs on ebay are like $500
V2 axles $600

So if it all measures up, maybe for less than $1500, you can have it.

Id like to know if anyone has the measurements of v2 axles and diff all together (without outer cv's) and see if its the same length as v1's axles and diff....

Im most likely speaking gibberish but hey its a thought

I got 3-4 friend on stock v rear diffs and axles running low 10s in the 1320. That's high 600whp low 700 whp range for that weight car.
Yes, tank would have to swap.
And great idea on seeing if we could use v1 axles. Heck I would buy aftermarket axles from someone if we could find a way to mount the v2 diff. Dss and Hendrix have adapters for the ds.

Im really curious about this. I was planning a 10+ camaro diff swap but if kinda rather just bolt a v2 cradle in and fab mounts to fit around the fuel tank. Then theres always the brake system to consider

iTrader: (2)

What kind of gear ratios come in the v2? Is the diff easily regeared? Do the v2 and v1 share the same driveshaft couplers?

The amount of talent it takes to think this through and actually do this is admirable but time is money. Even if this swap were fairly easy, I couldn't see it being substantially cheaper than an 8.8 swap if you value your fab time at just $30 an hour.

So you're telling me there's a chance...

If the v2 cradle bolts in then you could more or less use any diff from a 2nd gen caddy which might be a large improvement over ours.

But i dont get the point of all this, many guys have done 8.8's and done nothing more than burnouts with all the money they put into the rear ends. The v2 guys are out hitting drag strips like they get paid to do so.
