Well Im sure that you wont have to upgrade your tune your ecu, but there should be a little bit more power increase....depending on how much you plan to boost, your should only see significant increases during higher boost (16psi+). Thats from my experience. Hope that helps

On the Red Top S13 motors the GReddy manifold is the collector and runners so it is a bit or work. You will need to transfer injectors, all cables, sensors, etc etc so it wil theke the better part of the after noon. If you do it go ahead and get a set of o-rings for the injectors and all gaskets (don't be a silicone junkie). You'll only notice the diff above 4500rpm but it is about 20hp at 5000rpm and 33hp at 7500rpm from when we did a dyno on an S14 GReddy Intake Manifold. Note that this was on a S15 turbo set at 15lbs boost. For the money to hp value it is very good. Keep the inside of the motor clean also or your going to have issues.

Right , Thanks for the info. I might as well go with z32 maf and 555 injectors with a rom tune while i am at it.

not trying to thread jack, but what about a stock black s13. would u have to get it tune for the manifold?

nope but it will take 3-5 days to see full hp gains as the ecm will actually adjust fuel settings after a few drive cycles.

Do you have a fuel computer? If not I would go with a GReddy Emanage Ultimate, map sensor (GReddy) and iat sensor (AEM). You will lose the maf altogether with the setup and if you have to spend $150 on maf and $300 on a fuel computer you have almost payed for an emanage. The Emanage Ultimate is my highest recommendation for ECM tuning. Why pay 500 for a Rom tun that is a one shot deal, upgrade and you need another rom tune, say goodbye to a grand. The Emanage Ult is super easy to setup and you can even set a target afr and it will do the basic fuel tune for you. If more people would install one it would mean less posts here for troubles and more burnout/drift posts! btw you still retain OBD2 functionality and has an internal troubleshooter for motor problems
