Which Exhaust manifold is best for an 16g in a 2g

[RedDSM96]

I DECIDED TO PUT ON A 16G ON MY 2G BUT I WANTED TO KNOW WHICH EXHAUST MANIFOLD TO USE, THE 1G OR THE 2G MANIFOLD. ANY HELP WOUL BE APRECIATED.

as long as your stock one is not cracked(wich is'nt likely but can occur) thats the one you want.

You should try the DNP exhaust manifold. I have one, and I love it. The big 16G used to hit full spool around 3800~4000rpm, but now it hits 18psi right under 3400rpm. See the difference? If you have $500, go for it.

You can port out yours if its not cracked or anything. But if you are looking for aftermarket take a look at a ported EVO III mani. www.forcedperformance.com that should hlep.

Great post im about to order one. Any issues with elevated under hood temps. You know who makes those right was that spool reduction from just the header or was your old one cracked?

this thing is pretty sick. i might sell the ported evo and get one of these if it helps spool up.

cheap= port ur 2G manifold
moderate= EVO 3 manifold
outragous= look ^^^^

That is exactly what I got under the hood.
I didn't have a cracked manifold.. instead, I had a ported 2g manifold and the DNP exhaust mani still helps a lot. I still don't know why the header helps so much. No issues with elevated under hood temps yet, will let you guys know if anything goes wrong. BTW, after driving the car hard, the color turns from Chrome to rainbow color, very very cool.

#1. Caps lock off
#2. Like everyone said depeding on how much money you have to burn although I would not suggest getting the DN manifold unless the 16G is going to be your last turbo. Becasue if you evern switch to a garret turbo you will need to weld a new flange or get another 500 dollar manifold.

Nah, the Mitsu flanged manifolds will bolt up to the PTE housing based turbos and FP's excellent turbos, Green, Red, 3052, 3065. You dont need a Garrett T3/T4 turbine housing to go fast anymore.

I dont doubt the manifold helped spoolup. I just dont think a 16G should spool at 3800 rpms. My PTE 50 spools at 3500 now.

L2RTSiAWD:

is correct, its a waste unless you plan to use a mitsu flanged turbo for the rest of your days

 

[assa 98gsx]

the old t25 used to hit full spool(15psi) around 3000~3100 rpm, I am not surprised the big16G hit full spool a couple hundred rpm later. After the dnp manifold, I see 1psi at about 2800rpm, and hit full spool(18psi) around 3300~3400rpm. The observation was made by myself so it might be a little off, but the power gain was enough for me to notice the difference.

Who makes up that manifold?

It looks like an OBX unit (which is total junk and are sold on ebay for $125.) But OBX uses really thin flanges and those look like they are 1/2 inch. The main issue with the OBX manifold like that is the stainless piping attached to mild steel flanges. The two expand at different rates and cause the welds to snap because they are not expanding as fast as what they are welded onto.

I would like to see about that manifold some more, where did you get that pic from?

 

[jdmawd]

either way 3800-4000 is excessive for a 16 turbo. On a good note i think im sold on the dnp header.

you have a Pm

 

[DSMJim]

DNP makes the header. Where do I get info about them?

[EDIT] Ok found their site.. http://www.dnperformance.com/ Interesting stuff they have. Still wonder about the manifold cracking tho... And I have a PM...

That is one of the baddest turbo headers I've ever seen period..... Let alone for our cars.

FWIW, my Big16G spools to 17psi by 3100 in 3rd gear, and by 2800 in 5th with an EvoIII manifold.
