best rb25det exhaust manifold?

[dookiedang]

ok guys all im looking for is whats the best aftermarket exhaust manifold for an rb25. i might be picking up a steal of a deal on a s14 with an rb25 soon and it has a no name turbo upgrade with a no name topmount exhaust manifold and no name wastegate. i dont wanna keep it because it might crack on me under a lot of boost. i was wonder what would you guys recommend on a good response turbo setup with a exhaust manifold. im sure theres a lot of thread b4 but i cant find any. if you guys have some just post up the link on here. if not then give me some advice! thanks.

fullrace twin scroll is a nicely fabricated manifold. I, though, have a Apex'i top mount cast iron manifold on my 25. that bitch aint gonna crack at high boost.

what about those X02 crap? im pretty sure thats what the dude has on the car that ima buy. he is running 10psi right now and it seems ok. has anyone ever used it? just wanna see what it can handle.

you forgot to mention.
1. the apexi manifold is made for the Apexi RX6 turbo so you'll have to make a flange adapter to fit other turbos.
2. the apexi manifold has the wastegate on the buttom where you'll need to relocate(modify) for LHD cars.
if you ask me what manifold would I run on my RB.
I would custom make a logstyle with big diameter tubing and brace the crap out of it.

X2 manifold? anything made in china will crack depend on how hard you push it.
drag ok, drfit nono, don't even think about tracking it.

if you are really concerned about response, see if you can find an unequal length runner manifold (like the tomei expreme for the sr, not sure if its unequal for the rb). One of those matted up to a GT3076r/GT35r would be supper snappy with the right cams and throttle body (q45, kr engineering, etc)

a few companies to look into..
full race (as stated)
peak boost
lovefab
HPI
Greddy (but they require you to run a mitsubishi turbo with the flanges they put on it)

good luck :)

6boost is the best deal out there right now in terms of quality for the price.

ive checked them out, looks pretty decent, but are they only overseas? cause all ive seen them in is Australia.

where do you recommend getting it custom log manifold made at? and around how much would it cost to make one?

I have been keeping in touch with cxracing and i recently found out that they are in the process of making a top mount turbo kit (t4 i think) specificly for the rb25 and rb series motors. he said development could take some where around two months because of other various projects.cxracing is one of the few companies i have seen out there that puts their kits they make out on the market AND DYNO TEST them with great results. the cool thing is you have the choice of either the manifold or the kit. i dont know about you but I'm going to take my chances with cxracing
