3vze headers?

[Mikes95runner]

I just want to get rid of that stupid collector behind the motor and let it breath. What's the cheapest way to do this? All I've seen is 500$+ for headers. Any info would be great. Or if anyone has something for sale I'm open for just about anything.

Unfortunately the headers for this application are all expensive--$500 is actually on the low end. That IS the best way to eliminate the crossover, though, because it not only gets rid of the hot spot around the head that is the main contributor to head gasket failure, it is also the best route to gaining power on that engine. Without headers, none of the other mods (intakes, computer upgrades, etc.) can come close to their optimum gains. An engine is, after all, an air pump, and if the air can't get out quickly, you can't get more to go in it. Northwest Offroad and Rocky-Road Outfitters are a couple sources for headers off the top of my head. Best of luck!

Summit Racing... $600.
That's as cheap as I can find them.

I've been doing some research on this for our 1990 4runner(3VZE, auto) , and Northwest Offroad seems to get the best reviews. Dealing with the company seems to get mixed results though. I'll eventually put a set of these headers on our truck.

I couldnt find a price for the headers on their website though.

only ones left out there are doug thorelys.

Just run a passenger side manifold on the drivers side, cut the flanges off your crossover pipe and build from there. A body lift would really help though

From personal experience, I agree on both points--NWOR does make nice headers, but the guy who runs the place and answers the phone can be...uh, "cantankerous" (grouchy, moody, etc.). As for the price, their engine swap headers ran about $750, so maybe a bit less for the 3.0 units (or not--can't say for sure). Yeah, it would be nice if he would advertise prices...and have realistic hours...and not be such a jerk...and...well, you get the point. But the headers are well-built.

I've been waiting for a body lift before executing my take on the crossover elimination mod.

LC sells them on their website, they are pretty spendy though.

Yea I think I'm just going to bite the bullet and go with LC

only problem i see with the lcengineering headers is that you spend just as much as the other brands but you dont get the crossover pipe. you either have to fabricate your own or buy their crossover kit

I am running the LC headers with crossover pipe, I would pass on their corssover pipe if you are gonna wheel it. I had to get mine redone because it came underneath the transmission and that was their 4x4 version. Just my .02

So which brand of header is our best buy ? an how important is having a crossover pipe in it ?

Crossover pipe is for the y-pipe for the O2 sensor. It runs underneath the truck not behind the motor. Now I have bottomed out both axles before in mud, snow and ledges and no damage to the crossover (stock lift too!) but I can see why there could be damage but I don't off road like I should.


Best buy in my opinion would be Doug thorleys but there are no flanges for crossover and y-pipe so welding is a must. The clamps they give you are cheap.
