i've looked around and haven't been able to find anything, but does anyone know of any aftermarket intake manifolds? I would imagine a company like edelbrock or offenhauser could make a nice improvement over the stock jeep manifold. I've got a '94, and i've read about people using later model im's, what years are swappable and is there much performance to be gained from the swap? Thanks tony

Match porting works well. Match the intake manifold to the gasket and the head to the intake gasket.

Thats how its been with every one of my engine modifications. 99+ intake is the only one I haven't done, but I don't really care at this point. I don't think it will make any noticeable difference.

I was told that the older-style intakes were better suited for turbo purposes, i think the responder had said something about either the size or more even distribution, even though the pathway seems far less fluid than later models, I suppose with the compressed air it all evens out. Also for that interesting individual throttlebody setup previously pointed out (back in 2012) anyone know if there's any still being made or possibly found now? or will it all be self-fabrication work from here on out?

extrudabody.com has a complete kit its intake and throttle bodies its pricy but its worth it .......( The Kit is based on Clifford's Manifolds for either the Early or Late Motors. Manifolds dictate 45mm Straight or Taper Bore Throttle Bodies, Includes the I6 Silky Smooth Linkage system, filters, and TPS. Note: Injectors are not included.) $2.000 this is the only after market kit i see out there if i do find another one ill let ya know! heres a pic of it alone and on the motor!
Damn that is nice and looks like an Edelbrock alum head on it also, with a lot of port/flow work done I bet.

FYI, here's an in-depth article for a 2k manifold swap on a '93 4.0 GC.
