Guys,

I own a Accord SIR-T and I wounder what else I can do to increase power/torque?

I will change header and exhaust soon, and now I got a HKS super power flow.

 

That's already a pretty tweaked high compression motor, not much easy power to gain. Start with the bolt on stuff like cold air intake, header, exhaust.
Where are you from anyways? No SiRs/SiR-Ts in North America.

 

I will change header and exhaust soon. For cold air intake, I found it's hard as the original air box occupied the only path to the front bumber, and the damn box some how attached to the battery holder

Beside these, what else I can do? as parts are not mcuh for this motor.

By the way, I'm in Hong Kong.

 

Well that's a car that was never available here so I dunno about fitment of parts or availiability.
Was that motor hand ported/polished like the Type R motors? If not it's only expensive internal work like this that's going to get you more power I think.
Do you know if the motor has a single or dual runner intake?

 

I don't think it has as it is stock standard when I brought it.
It used to be a company car in japan, hence I guess they won't spend $$$$ to do that.

It should cost around US$300 to do that I think, do you think it is worth it?

"Do you know if the motor has a single or dual runner intake?"

I have no idea. A bit more explain wound help.

 

you are freaking lucky to have an SiR-T

 

Do you have any pics of your SIR-T? We would all love to see what we dont get over here

Dave is referring to a dual stage intake manifold vs a single stage. Our H22a's (cousin to your F20) has an IAB and a vacuum tank that at high RPMs open the runners for more top end power, when they are closed they help make midrange power. The Accord Type R has just 1 set of runners like the Integra Type R and B16a for even greater top end gains. A single runner setup is more desirable in most applications.

 

How can you tell if it has from the motor? I'm not that technical. So please tell me how to find out.

I have brought this car for nearly a year and I still haven't took a pic for this car!!

I'll try to take some photos and post it on site

 

By the way, if possible, can you show it to me on photos?

I really want to increase performance for this engine. Too many Subs and altezza around.

 

Altezza's, Its like the stunna's are going world wide, hehe.

its a car over there bud.

 

Well, I recommend a turbo setup. Get some pistons out of an F22B1, and slap the turbo on and you will make some power.

 

hey CF4 Owner, i know Hong Kong has a lot of JDM parts available... i used to live there... any way you get your hands on some 5Zigen parts for me..? email me at accordexchange@hotmail.com

 

Oh business time hur?
what would you like???
I can help for sure......

 

Do I need any special mods to do that? I mean are those pistons can fit in there without any problem?

By the way, will that be too dangerous to throw a TB in my DOHC engine?

 

All you would need to do for the internals of the engine is to replace the pistons with the F22B1 examples. Other than that, it is all external work.

 

you got any idea of the pistons size for F22B and F20B?

 

F22B is 85mm bore... Not sure about the F20B.

 

I checked at honda japan web site, F20B is 85mm X 88MM. what about F22B??
85mm x ??mm
