A stock 4.0 can take 8-9 some times even ten psi. Look at boostwerks thread. If I do one I'll be going for 5

the motor in my xj was turbo'd.


ive done some more reading, and people run 8 psi on the lq9 all day long, they don't do much more because of the higher compression ratio, and the fact that 8 psi with the right mods elsewhere gives a shit ton of power. (more than I will ever need I hope)

mines gonna be pretty stock for a long time anyway

Forced induction would be pretty sweet, and in your case if anything happens you can pick up another one for cheap money.

I'd love to boost my 440. My uncle said 8 psi all day long on the factory bottom end if I just add better head gaskets/head bolts. I'd be over 700 HP at that point.

While it would be sweet, I wouldn't do it just because of the amount of stress everything else would deal with. Not to mention the cost of the clutch. I can't imagine wtf the price of that would be.

What did you use to tune it?

I didn't turbo it, in fact when I owned it I didn't even run a turbo lol.

They say the stock gm manifolds weld really nice too. Its nice knowing I have the option for some crazy power out of this thing and I don't have to be a genius with a shit ton of cash. I know I will probably never do much to it though.

Righteous. Yup always nice knowing you can always add more power.

Hurry up and bolt the thing already.
 
Re: THe NAC Lots-O-Post Thread

Workin on it. Even if it costs me twice as much as i predict to get this thing in my rig, its still gonna be cheap lol. Gonna make up some real motor lift points and motor mounts this week.

The block only has 4 holes per side for the motor mounts, and none anywhere else even remotely close. They say its fine for high horsepower street cars, hope its fine for a rock bouncing rig.

Gonna make them out of 1/4" methinks. And completely box them in to the bushings.

I believe it, I've heard them. So now that your buggy and everything is gone, are you gonna get a mild XJ to at least come hang out with us on the trail?

Waiting for the boat to hopefully sell this weekend first but I'm toying with either an XJ or MJ to bring out. I never had time to work on finishing the buggy the way I wanted it and didn't use it enough. I figure most likely an XJ again so I can bring people along if need be. I actually miss the Camo XJ. I could wheel the hell out of that thing and still drive it a couple hrs back home. I actually kept the header panel from it as a memento. I also contemplated another buggy along the lines of what I wanted but w possibly moving again and kids and sports the less work I need to do the better. I have a couple in mind.


Don't worry T-dawg I'll still hang with u!
 
Re: THe NAC Lots-O-Post Thread

I'd bet you'll be fine. I'm willing to bet people mostly have problems with the 4.0 ones because the bolts loosen up anyway, and those are only (3) 3/8" bolts.

1/4" should be mint. That's what mine are, fully boxed. (3) 7/16" bolts per side in shear through at least 1/2" cast, then a 9/16" in double shear for the bushing to the frame. That 440 ain't goin' nowhea.

What's your estimate for the total cost of the swap?

hell no. I'll use a telegraph before I do that STOP

I was looking up stuff for a friend who wanted to put a 4.3 or a 350 in a 2.5/5spd YJ... apparently this is the easiest way:

3 bolt sbc pattern and 4 bolt ls pattern on one plate, bolt to motor, bolt to motor mount.

I have no doubt it'd fold in half if you jumped it though.
 
Re: THe NAC Lots-O-Post Thread

im at denver airport checking out the crazy murals and conspiracy theories. its pretty wild stuff, it cracks me uo everytime. everything from the underground bunkers and warfare stuff.
 
Re: THe NAC Lots-O-Post Thread

Not including the cost of the motor. I'm pretty sure I have it below a grand including running new exhaust. (just some cheap pipe and some chambered mufflers).

The big kicker will be my cooling system (not figured into cost). I don't think my current radiator will be up to the task (for a 4.2l inline 6). It worked fine for my mild 305 though with a mechanical fan. I will definately be going electric fan with this one, and have plenty of room up front for a bigger radiator after some sheet metal chopping and whatnot.

im starting over from the previous owners setup. its a little bit hack if I must say so myself.

Yo incase you don't know stock 6.0 manifold bolts rust easily and break, so replace dem shits while that shits out
 
Re: THe NAC Lots-O-Post Thread

Question for colin/ people that have put motors in shit.

Should I bring the chassis mounts closer to the motor, or the motor mounts closer to the chassis? Does it even matter?

I think the mounts closer to the chassis would be nice because there will be more room to wrassle stuff around and work on stuff when removed, and less stress on the chassis. But with the mounts closer to the motor would seem to put less leverage on the block bolts.

Am I thinking about this too much?

(Talking about the actual bushing in relation to the block and chassis)

Yea, after like 10 new england winters. My manifolds are in perfect shape, no reason to replace what isnt broken. Ill probably put some kinda high temp paint crap on them too for bling points.

bushings closer to the block will create less distortion and keep the engine in place better. the closer to the center of the engine, the length of the lever trying to twist will be less. there will be more stress on the chassis mounts but you should have more room then to add additional bracing.

at least thats how I look at it.
 
Re: THe NAC Lots-O-Post Thread

I thought the bushings further from the block would keep the motor in place better. I mean I know they could potentionally distort more with more leverage on them. But the closer they are together the more the engine will move with the same amount of distortion.


Im probably way over thinking it.
