Hey all,

Have a question for yah. I finally got my turbo and the intercooler just came in!! All that aside, i am having some trouble though with how i am going to create my forward Y setup. Basically, i have a Cali Spec, and with that comes the straight ended Y pipe that attaches directly to the rear manifold/header.

I have attached some pictures to further help you understand what i am talking about because it is somewhat hard to explain.


So basically, as with the Cali Y pipe which is shaped



as all of you know.


Here of course is a Fed Spec which models EVERY forward Y setup i have seen with two vertical 90* bends..



here is what my Cattman looks like as it is right now, where i would try and make the forward Y.




Here are some pictures that i found off of a maxima owners website of the difference in the CA and Fed speck Manifolds...

Would my best bet be to just buy a fed manifold? if possible? and just replace the extra O2 sensor in the manifold to one on my "mock up forward Y"?


There in lies my problem. . How am i to create my forward y set up. Have any of you encountered this problem, and if anyone has any pictures i would appreciate it greatly!

Thanks,

Tiler

 

You can do a reverse Y which will rap around the rear of the motor and come up. That is how mine is ran.

 

Yes reverse y would be an option and just wrap the pipes good with heat wrap. That would probably be easiest. If you get the fed manifold you could just do the forward y.
Just by looking at the pics it looks like those triangle flanges are asymmetrical and that is how they were able to point the y forward instead of cutting the flanges off and rewelding the pipes. I got some pics here. http://forums.maxima.org/supercharge...rbo-setup.html
My build thread coming soon!

 

thanks guys, yea of course i was planning on using less piping but it seems that doing a reverse Y will be the easiest option. Im going to keep them still open though, maybe if i get my hand on a fed spec manifold i can figures something out. Thanks for the write up as well maxgtr.

 

I have a fed spec manifold sitting here if you would like to buy it? I could do 40 shipped if you want it let me know.

 

Thanks kzoosho, ive decided that im just goign to go reverse y and just set it up that way. I appreciate it!

 

I say reverse or forward is around the same, I'd choose a path and find away of achieving good clearance and little temperature problems...maybe heat wrap if u needed to! but of course I think the forward y-pipe is the cooler one,lol.

 

No prob. I am going to do a fed spec conversion on my 99 Maxima.

 

Let me look around the garage, I might have one I can send to you.

 

If you do have one and Tiler doesn't take it, I will. Im assuming you are referring to a reverse Y?

haha, is it the Y or Fed Manifold your talking about?!

 

The Y. I figure if that is what he is offering and you can't take it I will and when you are ready we can get a copy of it made for your car.

 

I need the Y pipe, I do have a few manifolds laying around.

 

A CA--> Fed conversion is very easy. You can also get O2 simulators from Cattman for the rear O2s.

 

Not anymore. Pretty recently, legislature has made it so O2 sims are illegal and have been banned. O2 sims are hard to find now.

 

We tried to get him to do the swap but he said hje is going to keep the cali spec.

 

Really? Wow.
