Pictures of a throttle body bored by King Motorsports
I recently sent out a stock H22A throttle body to King Motorsports to get overbored. Here are the results. Note: In some of the pictures it was hard to get the lines on the ruler to line up on BOTH sides of the opening.
In one of the pictures I took close-ups of the individual ends to show that the ruler was in fact dead on.
Inlet: 66mm (the picture is deceiving)
Outlet: 62mm (this one has close-ups)
This is a blown up picture of the inlet on the throttle body. (The bad angle makes it look like it's 65mm)
This picture is of the throttle body ON the upper portion of the intake manifold.
I opened the butterfly plate so that you could see through the whole thing.
This picture is to show how King puts the TPS back on the throttle body (new allen head nuts)
Thats nice work, i didnt know King did machine work also... of course i geuss they should if they are running race teams now (i forget which serries though). I love to see pics with rulers!!!
Originally posted by laughin2.2 I'll be the arsehole and ask. Dyno numbers and price?
Looks like some really high quality work. Can you use the stock TB gasket?
I haven't dyno'd the car yet. The throttle body isn't even installed.
The price is broken down as follows:
Overboring: $150.00
Handling: 3.00 Shipping/Ins: $ 10.00
Total:$163.00
Yes you can use the stock throttle body gasket. If you start overboring the outlet side then obviously you're going to have to enlarge the gasket as well. I don't know if King Motorsports will do this type of work though, then again I didn't ask.
A bored TB won't do much if anything for power without a lot of other mods. With a larger plate installed, throttle response will be a lot more touchy since for a given throttle angle the throttle opens more/faster.
Originally posted by SK Honda 7 what other mods might be helpful to TB to see some gains...
how about cams and IM ?
Yes and yes. This was done to compliment my cams (under my bed) which are getting installed later in the spring. I'm leaving my intake manifold alone though (have to put a limit to the money spending somewhere).
After the following is done this spring I will go back down to inlinepro in VA to have sgt tune the car.
Looks good Joon. I am trying to put tha finacial limit on my mod/build plan for this up comming year as well. Such a hard line to draw.
What cams do you have that you are not planning on upgrading the valvetrain with all that? Crower stg 1? Are you keeping the pistions or going with type s?

Nice joon. You should look into getting atleast your stock IM sent out to get etrude-honed. You should talk to RLZ on honda tech, hes in NC and could do it for fairly cheap to compliment your TB. And maybe another header, like maybe the 10-94, or imagine engineering, pro speed, smsp and even hytech. WIth a nice header and exhaust combo you should be able to hit 200hp with cams. SGT will be able to help pull that off. In a couple of months im about to get my car tuned also. When do you think you will have everything all ready?

Cams
Cam gears
Power Enterprise SS Timing belt
Intake manifold gasket
Bored throttle body
what so special about INLINEPRO that you cant get it done up here? What are you going to be using as far as ECU?
what kind of cams?

Well whats special is that this guy SGT uses their dryno to tune cars. Hes one of the best hondata/ all around tuners in the whole country. That is why. Va baby!

Crower Stage1, I don't care for the TypeS cams and if I went with anything higher than the Stage1's I'd be upgrading the valvetrain and I'm not planning on doing that. This might be the real end of line in terms of mods to this car.

No honing since it's more money, even if it's a little it's going to add up in the end and I have other plans that need more attention than the car anyway (house/my wedding in August). I'll be keeping my Fujitsubo header too. While a SMSP would be nice (still haven't seen dyno's though) it's not an option right now. I don't know that 200 whp is going to happen with the Crower Stage1's either.
I'm shooting for a mid-May completion date. It'll probably be done before then but that's the same time I dyno'd the car last year and I want the temperatures to be about the same.

I can see you don't read up on Honda-Tech, but that's OK...search around there to see what he's done. He's a walking Helm manual to put it one way.
As bolivianfuego already stated it's not inlinepro, it's sgt. Even without sgt in that area, inlinepro are pretty good and believe it or not it's cheaper to actually drive down there to get it tuned than get it tuned in NYC. I already got the car tuned once in NYC and it was definitely cheaper when I went down to inlinepro last year. Stock ECU (with V-AFC). As for cams see above.
Your getting married joon? Congrats bud. Sure you can break the 200 mark or come close. Ive seen on h-t many guys come close with a stock jdm h22 with just i/h/e. You could come really close or even do it with cams. Thats like 5 extra hp right there. Pretty soon your gonna be at the 190+ mark. Good luck.
Joon, you really won't see the benifits of the TB unless you at least port match the TB to the TB opening as you can see the manifold though the open TB. I'd minimally extrude hone the IM while you're doing that unless you can find someone with an upper that you can buy.

Actually I have an upper portion and I had asked King to match it but they didn't. I guess you're assuming there's a small lip between the tb and the manifold correct? It may look like there is one but there isn't. I tried to show that by taking pictures of the ruler on the backside of the throttle body and the opening on the upper portion of the intake manifold.
