I have a buddy that has many sets of grand wagoneer axle sets, he also has a set of GM10 bolt with 4.88's (not sure what the Chrysler axles are geared to).

My question is two parts:

First I need to say that I am currently rebuilding a 1995 1uzfe for boost (M90 supercharger for now), and using a Megasquirt setup for engine management. **Question** Should I do an SAS before doing the 1UZ swap or after (I have both oil pans so that won't matter).


**Question** And as far as axles should I go with the GM 10 bolt, or the Chrysler axles? I have no real info on the Chryslers other than I have many options in gearing.

A little about my truck.

It's not my daily, its a play toy. I currently push 36x15.50's but plan to go to a 38's after the 1UZ swap regardless of SAS or staying with my IFS lift. I currently have Toyota 4.88's and my trans is about shot (A340H). I will be using a converted A340E probably but am looking into either using the W56 or R150F (I'm just not sure they will hold up to the power). It's purpose is undetermined honestly probably just some occasional trail riding a the local off road park. I honestly just like building things.

Sorry for the long winded post, I figured that I needed to get all that info out there so anyone that might help would know where the truck was headed.

Thanks in advance.

 

I went with the waggy 44 on a 3rd gen. cheap and lots of universal parts. I'm also using the stock toyo rear end... Diff ratios but close enough it won't matter.

 

What was your gearing in the rear end?
