Stroked 4.0...What else can I expect to need to do?

I picked up a 2002 TJ X automatic with engine issues. Decided against a V8, going to stroke it instead. Nothing too crazy, going to a 4.5.
It already has a 4" short arm lift so I'll probably do a 1" body lift so 35s will fit comfortably.
I am figuring on:

The bill from the engine rebuilder = $1500-$2000
Labor for engine pull/reinstall = unknown quantities of beer and pizza
Possibly gears = $1000 (may try the 3.73s for a while first to save $)

I am mainly wondering about whether or not there is anything I'll need to do/upgrade for everything to work as it should. And will I have to run higher octane gas?

Thanks in advance. And here's a couple poor quality pics:

I had a stroker in an MJ that i had. I ran 93 octane in it. As far as other things with 35s you will need bigger brakes, upgraded steering like a currie setup or something, CV driveshaft and SYE. Other than that it is mostly personal preference when it comes to everything.

Welp, if you plan to wheel at all and have a stroker and 35" tires, thats pretty much exactly what it is

Yeah, it's a D35. I know it won't last when I start really using the rig but it should do me for a couple months until I figure out what I want to do with axles/gearing and free up the money to do it after spending $ on the engine.

I need to keep this project from costing me too much so I'm going to try to wait for some really good deals before I jump into anything.

I would love to build my engine eventually. low comp forged pistons/rods and a stroker crankshaft (hopefully forged) and maybe a power adder =)

Just curious, what sort of engine issue does it have that has you looking at a stroker? Not saying you shouldn’t do it, just wondering why (a 4.0 that new rarely has to be rebuilt).

Then just stay with 33s, or what ever tire size you have. There's not reason to go up the 35s just yet if you haven't even wheeled it yet and seen it's capabilities. If you just want it for looks or because you think you'll gain some magical amount of offroad performance then you're doing it for all the wrong reasons.

You only need to run higher octane gas if you increase the compression ratio. I personally would keep it close to stock and just run regular 87 octane.

Oh son of a....



Don't always associate the jeep in someones profile to the one their posting about, because people can have more than one Jeep, but know I'm curious, did he ditch the TJ for that JK?
