Obx Manifolds & Td05 16g Vs Gt2560-5

[sickr33]

just a quick one i have searched and heard good things about OBX manifolds

so my question is who has had one crack??

im interested in buying a set of twin low mounts for my gtr.

also

i have gt2560-5 turbos now still on run-in tune for motor but was wondering how would a pair of TD05 16g's compare also they have external gate

i would like 500hp, maby a bit more but not sure if the 2560-5 will do it with out stupid boost on my motor

built bottom end

ported head

260-9.15 tomei cams

all supporting mods

[STATUS]

bout the same, what rears are on the td's. there are 2 sizes

i have obx dumps in my gtr and are good,

i orded obx manifold and they didnt fit so they where send back and gave my money back and i spent 4hr porting the std manifolds that flow great.

apart from them not fitting as the should they looked good lol i was just short on time to wait another 4 wks for another set to arrive or i would have.

they also come with a very good warranty life time warranty i think?

^ Yeah as stated factory manifolds are the way to go.

Ryan the -5s will EASILY make 500hp. Hell they make 500rwhp(370rwkw) on 18-20psi which is fine for any build.

You will crack 400rwkw on a bigger $$ motor and more boost however 370/380rwkw on 20psi is standard output to be honest - and thats with factory manifolds

I mean you are paying what $700 or so landed for OBX manifolds when Tomei ones are $900-$1000 landed.

If you really must/want to change them, i'd be spending the slight bit extra and slapping -5s onto those

End of the day its a lot of dicking around and expense considering you will get no discernable performance gain. Add to the fact you are then complicating the setup considering what you have now will fit your requirements and then some.

Are you looking @ TD05 high or lowmounted?

[sickr33]

they are low mounts im happy to keep the gt2560-5 and crank the boost up to 24-25psi if needed to make 500hp

also looking at modifying stock manifolds to suit twin 38mm gates

do you think there would be any performance gains in doing this?

reasion i ask is i have a 3" jasman exhaust on the car because my Kakimoto Racing N1 Dual Exhaust cat back is way too loud for street use.

[R31Nismoid]

There are no performance gains going to external gate, just over complicating everything.

Also that exhaust is too small - you need at least 3.5", more likely 4"

With two big/decent sized mufflers it won't be that loud at all. My 3.5" exhaust is around 90dB with two of the biggest mufflers possible - still makes power fine.

You can get obx manifolds for about 450 delivered, USA exchange is realy good atm.

But with -5 I'd stick with the std manifolds ported.
