rew intake on s4 turbo block
ok tomorrow im picking up a cosmo 13b-rew intake manifold. im getting upper an lower an i wanna know if it will work on my second gen. i know the injectors are different an i have to tap in my two oil metering lines. but my thing is will the manifold bolt onto my block.

with an adaptor plate you can attatched the rew uim with s4 lim
so say you can only use an s5 lim but if you enlongate the holes on the manifold it will work
theres alot of info on here about this

Okay if you are picking up a Cosmo lower and upper manifold then is not a REW setup,REW manifolds are twin turbo third gen manifolds.The lower cosmo manifold has huge secondaries intake ports and they are in a angle,the primaries are huge and in a different position that S5 or S4 turbo irons and on top of that you have the upper right hand bolt that wont match the S4 block so in other words they wont work,If you want a better intake system get a S5 lower port match or use a adapter plate and use the REW twin turbo manifold(not the RE cosmo unit)and REW throttle body(bigger diameter butterflies than cosmo unit)If you pick up this manifolds they are gonna be useless to you.

What are you trying to accomplish?
If you do not have an S4 LIM/UIM at all it should not be too hard to find a set.
If you have the S4 LIM and want to use an REW UIM you can use an adaptor plate thats fairly easy to make.
I am not sure a Cosmo UIM will fit an S4 LIM as I no longer have one around to take a look at and never tried it.
I am fairly certian a 13B-RE UIM will fit the S4 or S5 UIM, and would likely be my choice, but am not 100% positive on this.

or just forget the whole RE/REW manifold idea and get a S4/5 turbo manifold set and do it properly. not like there is much gains from all the headache of swapping the manifolds.. the only reason for even using an REW upper on a TII lower is for more space to work on things without having to rip the upper off, or IC piping locations versus the stock throttle body location/aim or superior TPS.

Here is a pic of my setup and a list of what was used in order to make it work.
REW upper manifold,throttle body,tps and greddy elbow.Some grinding needed to
fit fuel rails.
Port matched S5 lower(aluminum was added and runners port matched)
Custom intake gasket
Modified Cosmo RE oil filler neck
REW throttle cable
and some other bits and pieces.

so its to late already got the upper its a twin turbo rew upper. he didnt have the lower so i dont much care. as for just doing the lim s5 manifold im going to do that an just make a spacer. the reason im doing it isnt for hp gain or any performance just a cleaner looking engine bay. i can port match i dont really care much about that i port motors so its not a big thing. but ill figure something out with it i just like the rew look better than the re/fd manifold

Is not about porting the intakes,you have to add aluminum 2 the primaries runners and then port them that is if you dont want to spend money on the adapter,there is not enough material in that area and if you try to port it you will end up with a gap and a nasty vacuum leak,now if you do it keep the stock FD3S air intake sensor and TPS also the FD idle control valve.They are newer and easier to find that FC3S parts.Any questions ask me i done it a couple of times.
