C6 stock exhaust manifolds will fit and I think I heard gto ls2 headers will fit as well. But not 100% sure. Was thinking of doing a carb ls swap as well but it's going to be one hell of an undertaking. Good luck.

Thanks bro and yea I do a lot of research on how to make it legal and it's actually not that hard just a lot of extra money haha but if you go through with it then good luck to you too

Those headers are going to be tight Af....say goodbye to space

It isn't as easy as you think but doable. Unless you get the Erod package that comes with the carb sticker.

If you are also trying to use the evap system from a 240sx you have not done enough research. Ref will not allow you mismatching parts from different cars even if its the same family of engines. There is some flexibility in this if for some reason he can't find a part number and the part resembles the original part the Ref will pass it.

On an S14 I think I remember someone cutting up some corvette headers to fit. GTO headers fit with S13. Check out this forum for more info http://www.silviav8forums.com/forum/index.php

It's a long read. but he went through the same stuff as you. And he is finished.
I am waiting for a 300zx LS swap kit for my daily driver, it's 25years old and 225k on the motor.

[s14 ls1]

You should build your own swap kit then sell it. You would make bank haha

He was a member on here. S13 you need help with S14 and he bought the E-Rod package so you don't have to go to a ref you just go to a smog place with your carb number.

iv done my research. if you read this article you will see that you can use nissan oem evap canister and still pass. this guy did it. and s13 and s14 ls swaps are basicaly the same exact parts basically. there are a couple of things you cant use which is common sense but the most part you can go off a s14 and still use same parts as that person.

[SR20PWRALTY]

Which article? The one with the black s13? he has the E-Rod crate engine that came with a evap/charcoal canister its pictured on the bottom right.

You are right it could be possible to pass with the nissan canister if the ref some how over looks it or makes a mistake. The only problem is they check the systems to make sure they function with the OBD II port. If you some how wire up the nissan canister and use the LS1 sensor with the canister I guess but why go through all that trouble I would just use the LS canister.

The 2012 ls3 camaro headers would fit just sold mine

those would fit S14? With what mount kit or would you have to fabricate your own mounts.

Found this, said he used stock 2001 manifolds

[NISR20MO]

I have seen stock C6 manifolds used before, on the drivers side you may need to space it out with a make your own header flange and a extra gasket.

[SR20PWRALTY]

I have personally used 2002 Camaro headers with some grinding on the exhaust flange and 2005 GTO headers on the passenger side only. Drivers side only got 2005 GTO to fit. This was all for S13.
