some help with upgrading intake on D16y8 head
Ok so currently i have a JDM D15b with my Y8 head on it. im looking into upgrading the intake side of the head. i just currently got a cold air intake and was looking to upgrade my throttle body and intake manifold. now heres to the questions...can a throttle body be to big? i want to eventually turbo it and am just upgrading sections slowly as i go. im starting with intake manifold, tb ect....then building the head ect. but for now it will be all motor. i was looking at throttle body and see i can get just about any size all about the same price, i saw 70mm 68mm 66mm ect. would it hurt to run a 70mm all motor? any pros/cons? and same for turbo would it hurt or help? i wont be putting the tb on til i get a intake mani anyways so im not worried about port matching the y8 intake mani. any opinions on intake manifolds? ive been thinking about getting one of those OBX ones for the time being just to upgrade it some then maybe running the Skunk2 when i go turbo. any one know much about the OBX intake manis? i cant find alot on them. anyone know if the edlebrock is any better than the Skunk2? i see its like 100-200 dollars more. would it be better to just run a B series tb on a aftermarket intake mani other then upgrading the tb? any opinions on Tb spacers? have some people telling me get one then i have other people telling me it isnt worth the money. any help in ths category would be great! and also i do understand that i have to upgrade alot more before i can turbo im just trying to build on a budget. Thanks Guys!

theres not much point in upgrading the throttle body. hook a vaccuum gauge up and drive the car. as long as you pull 0 lbs of vacuum at full throttle there is absolutly no restriction there.
intake manifolds are a different story, they won't necessarily increase power, but they can shift your power band higher or lower.
honestly i wouldn't do anything. just leave it alone, it runs and works properly. even if you plan on boosting it, you can get 300 hp out of it on stock intake.

Depends on how much your going to boost your engine because like the guy said you can still get a lot of power from stock parts if your evently planing a extreme build get the parts or daily driver jus keep it stock and put a turbo kit on it should run fine up 6 psi anymore you will need head apr studs and the tb spacer is to make the air go into a swirl effect and atomize the fuel in a spinning motion to maximize fuel ecnomony

OP. Define your end goals. It makes no sense to upgrade these items on a stock engine. You won't make any real power and in some cases you may HURT your "power" output if you don't plan on tuning for it. If your goal if to make more power then you only have the traditional two choices; boost or swap.
If you really are going to boost it, and aren't just pipe dreaming, then stockpile all your parts and do it all at once. Anything less is just a waste of time.

6PSI doesn't mean anything. Throttle body spacers? Don't even bother. It seems some of you are actually buying into the marketing hype.

"10-15 psi" means nothing. Power goals are what you need to set, as well as budget goals. 15PSI from a T25, a healthy stock motor could handle. 15PSI out of a GT40? Well, I'd love to see the video.

Re: some help with upgrading intake on D16y8 head
I'm still learning about the different type of turbos. Maybe u can help me out on this stock motor I'd only like to push about 10psi, at least 8, what would be a good turbo to run for the boost? What's the big hype about T3/T4 turbos?
