I have a 68MM omni but im getting rid of it. But i could always return the b16b one and go with a skunk2 ALPHA 68MM if necesarry. Prefer to keep my low end so im hoping stock will be ok?
Engine:
B18c1 Block
eagle rods, Wiseco Low comp pistons (IIRC it comes out to about 9.5:1)
B16a2 Head, GSR Cams, Supertech valve train
Skunk2 intake manifold
Type R trans
Fuel:
walbro 255
ID 1000cc injectors
aem fuel rail/FPR
Turbo;
Go autoworks "prokit"
Ramhorn manifold
skunk2 3' catback
T3 Bullseye Power Batmowheel B252 -52MM Billet Compressor Wheel
-.55 a/r stainless turbine housing
-550hp rating

Even with the stock throttle body, you can still make your projected HP. You left out the MOST IMPORTANT PIECE....engine management setup.

Re: Throttle body for 400 HP
Because of ****-water gas in Hawaii is 91, like in California. And before you start the E85 Corn-syrup rebuttal, It's not that available there, nor should it be.
Camdizawg has a good potential setup here. Although it may take a little more boost pressure to get 400whp with that Batmowheel. Its basically smaller than what everyone here knows to be a T3/T04E "50 trim", with a much larger exhaust wheel that can hurt recovery spool in between gears.
But the rest seems relatively sound.

Re: Throttle body for 400 HP
The parts were Installed over a year ago, If i had to do it over yes I would go with higher comp, although car still has plenty of power in its current NA state. I got them in a trade i traded a GSR transmission for a B18c1 block that needed a rebuild, Eagle Rods, Wiseco Pistons and Arp Rod Bolts
@Nvturbo Engine Management has not been purchased (car is currently is NA using a basemap so it runs with my injectors) Still working out my tuner for all this and leaning twards HONDATA
@TheShodan Thanks you always have such great Info!

Re: Throttle body for 400 HP
Stay away from the Skunk2 stuff. They've been suffering from horrible sticking issues. The 68mm omni is more than adequate. If it isn't sticking and isn't broken then there's no point in changing it. There's no difference between a billet and cast throttle body other than looks and weight. They will both function the same and make the same power.
However if you haven't enlarged the opening of the intake manifold to match the larger throttle body then there's no gains to be had from using a larger throttle body. The smaller diameter opening is what limits flow.

Re: Throttle body for 400 HP
Yes that is my issue exactly...Ive only been looking at the alpha series as well, Billet it just to costly and seems unnecessary... I only see 66mm and 70mm in the alpha series, is 70MM overkill for a 400 HP setup?

Re: Throttle body for 400 HP
One of our forum sponsors sells quality 68mm and 70mm cast throttle bodies for well under 100 dollars. I haven't heard much in the way of negative reviews, everyone seems to like it and it works flawlessly
I'll try and find the link here in a bit.

Re: Throttle body for 400 HP
i use the stock tb for with 500 hp but thats on a victorx with that pretty big plenum. i also have that alpha 66mm tb i had on my n/a lsvtec. it doenst stick, the return spring is softer than oem. i did have to clock the tps sensor pretty far to get it close to within spec and then just adjust the max/min voltages in the neptune to final calibrate it.
for your goals i wouldnt find it necessary to go bigger than 66mm, but an oem 60 or itr 62mm will do just fine imo

Re: Throttle body for 400 HP
Haha thanks I chose to go with thermal gaskets with correct sizing to avoid that issue

Re: Throttle body for 400 HP
I agree stock throttle body, I made 520whp with a stock B16A intake manifold and a custom 64mm throttle body. When I stepped up to a VictorX manifold I went with the 70mm Skunk throttle body to eliminate restrictions, which has worked well for me.

Re: Throttle body for 400 HP
If your IC piping and IC is the same size as your current throttle body then going bigger wouldn't make sense. But most of us run stock and are well into the power
