Thought I would post my .02 here. I am getting ready to do a swap and was debating headers or manifolds - already have a SC, I like it quiet so had decided on manifolds. Started cutting up to mod the crossover and found this, they neck down the tubing and almost butt them together inside the flex coupler causing quite a restriction - Supercharged may notice it - . I cut mine apart and am going to butt weld the same size to each end. Just thought I would share.

If it makes you feel better, who am I, but I was running ~375hp through stock manifolds and even smaller exhaust preturbo (2"), so it will not have an effect whatsoever. But really idc, just throwing my .02 back at ya.

Sweet!!This measures 1.75" then is overlapped 3/8" on each side. I'll just make more boost on one side - the restricted side !!!

I don't understand that. Ah well good luck!

Is it possible to replace crossover on 94 3.0 pickup without pulling engine?? Looks impossible to get at!

You posted this in the wrong sub, but yes, you can do it. You have to unbolt the trans crossmember and either lift the tailshaft up to the bottom of the body, or drop it down to the ground. It will come out- it is a lot work!

How close is your fabbed crossover to the clutch slave cylinder? Are yall having issues with the heat damaging the slave or the rubber on the clutch release arm?

Hey guy how would you recommend doing the crossover pipe on the drivers side since I don't have the 3.4 downpipe that goes from the two to one collector? Would it be better to do it like the previous pictures on post #97 or is the two to one flange easy to come by? This is really my biggest hold up on getting the motor dropped in.

Thanks

Is this what you're looking for:

Thanks that is exactly what I was looking for. I was able to read the part number from the picture and autozone still carries it. I was not able to pull it by vehicle search but thankfully it's still available by part

So, a quick intro, I am fairly new to this board but have spent the last few weeks reading posts preparing to do a 3.4 swap in a 92 4runner that we just bought from my son. We have a 98 donner vehicle with a fresh motor. I am trying to determine whether to custom make my crossover or buy one from ORS. So my question is this: have any of you (That live in Ca) done either and passed the ref inspection?

Thanks for any input

SacRunner

Since it seems that you're in California, do not buy the ORS crossover. I'm sure its a quality component, but it will not pass the Ref's inspection. When I was working on mine (2012), a ref told me that I could modify the stock exhaust however I needed, so long as all the components were the same relative distance from the engine as from factory, and that I used the OEM Toyota exhaust flanges; since the ORS crossover does not use the Toyota flanges, it will not pass the visual inspection. The ref really stressed that the OEM Toyota flanges must be used, and while I cannot see how different flanges could effect anything, make sure you retain the OEM Toyota flanges (between the exhaust manifold and crossover, and between the crossover and the "down pipe" that has the upstream O2 sensor mounted in it).

That said, I had TOS (Toy Only Swaps) modify my stock 97 crossover and it passed the ref's inspection.

tombugg

Thank you!! That is exactly what I was looking for! I may give TOS a call. I also plan to visit the ref prior and pick his brain.

Awesome thread. Followed the steps and it worked great! Thank you.

I picked up a 2002 3.4 that has the double wall cross over so from what i'm reading means that I can't cut it up and rebuild it. I'm wondering has anyone ever looked at cutting up the cross over pipe, like in this example but using the 3.0 crossover as the donor. I was then thinking that the flanges from the 3.4 could be welded to the end of the tube to mate up to the exhaust manifold as well as the stock exhaust in the pickup. Thoughts? Thanks.

Did the pictures get lost?

Photobucket broke the internet, lol. I have all the pics, will work on getting them loaded back up.

dakotar95

any luck on getting the pictures back up? your post is the only one like it on the internet haha

josephfilben

Hey any luck with being able to upload the pictures again?

Jason4X4

yup!

Anyway, this is still going in the 4runner, had to pull it out and weld it up again a couple years ago because he didn't have any hangers holding the exhaust, and it ripped the bottom of the pipe off. So make sure you have your exhaust supported.

Also, these pics are now hosted on this sight, so if they fail, it's yotatech's fault , lol
