I was wondering if I were to take the stock d16y8 throttle body and intake manifold and bore them up to say a 60mm would I notice any power gains? I searched, but I couldn't find anything really. Thanks

 

i would say yes, but wouldn't be much gain

 

maybe better throttle response, but i doubt the power gains would be noticeable.

an easier way to go is to just get a B series throttle body, they bolt right up

 

Not worth the time.

Once you upgrade the valve train, and get some cams, then yes.

But on a D-series, your money is better spent elsewhere.

Yup like throwing it in the trash and getting a B.

In all seriousness, i think it would be great in additions to other things, like port and polish, cams and what not. You woudn't feel anything because the gains would be too small.

 

A B-swap isn't needed, and yes, IMO it's a waste of money.

If you're looking for a serious power upgrade, look into some sort of forced induction.

All motor is nice, but with a single cam, you will spend $$$ and be lucky to put down 140-150whp.

you could always donate it to someone who knows how to use it

 

i think the H22 Tbs are pretty big and i know that most honda TBs bolt up to most honda IMs

On a D series though, it's just not worth it.

 

well, buying a GSR TB would yeild you a 60mm TB for about 40 bucks. On a stock y8? too big. All that will happen is your throttle modulation is gonna be closed, kinda accelerating and straight to WOT maybe 75% throttle.

My 144whp build is with a 58mm TB. Granted, stock head ports and valves. When I take care of the ports and valves, it should be about 155whp. I will dyno the car with both the 58mm, and the 60mm. If the 60mm is good for 4whp or more, I'll keep it, but if its only good for about 2whp, i'll keep the 58 since I'd rather have throttle modulation, instead of something closer to an on/off switch.
