Well, it would be a shame to sell it... I say keep it. You WILL have to upgrade your diffs though. I would recommend upgrading to the complete X SS set-up - that would include skid-plates, bumper posts and shock towers - plus the pre-shimmed, pre-assembled diffs. You can do all that for about $100.. There's an excellent Savy chop-shop on US ebay.. I think his name is plc-man or something like that.. Just look up "Savage differential" and you'll find it..

Power-wise though the Axial 32 is an enormous upgrade over your old 25, so diff issues are invevitable I would predict... Just run it for now as is, but I'd be surprised if you make it through break-in.. Even with my 28 I was inadverdantly wheelying at 1/2 throttle on the 2nd tank...

Anyway, you've got a real torque monster there - so I'd keep it and have fun with it.. I know it can sound like a pain to have to upgrade stuff - I hate the idea too(You said you're a sucker for displacement... Well, no pain no gain.........) But now with the X SS setup, everything is really easy. When my diffs go I'm just gonna buy preassembled diffs from a chopped X SS and switch them out - no shimming or any of that...
