Si Factory Accessories / Performance Parts Released!

[zroger73]

I noticed that there are different model codes for the Si with and without the summer tires. Does that mean that they have to come from the factory with the summer tires, or is it a dealer installed option?

Factory.

I'm disappointed that there seems to be no mention of the HFP suspension. But I understand this is only a preliminary list.

Hmm with the Si having adaptive suspension, Im not sure if that would effect how hard it would be to throw on a different set of shocks and springs.

I loved the hfp suspension on the 08 Si and thought it was a good value. Hope something like that becomes available for non Si trims.

I can not wait to see the Si vs Hondata Hatch sport video.. It's coming.. haha.. Oh it's coming.

are they going to stop, or turn the steering wheel?

 

[ronmcdon]

I don't think there's going to be a lot of difference in straight line acceleration when comparing an Si to a non Si 1.5l Turbo civic w Hondata tune.

I recall reading the difference between the Si was just a factory tune. You may just as well be splitting hairs by comparing the two.

Be interesting to see how well the Si handles w it's suspension and lsd. On paper it looks good if not great, but who knows unless there's a test of the two.

I imagine it will either be a package deal with revised adaptive dampers and springs, or a "spring only" package that is designed to work with the existing dampers. The latter option being unlikely.

Or perhaps, Honda PR was misinformed about the availability of an HFP suspension for the Si.

After looking at the part images and part numbers...seeing the difference in the dampers and associated parts it looks like the shock bodies are a little shorter than the standard civic dampers along with different bump stops and dust boots as well.. but the springs are showing up the same part # front and rear which leads me to believe that the Si's lower stance might just be from the shortened dampers ( 1/2" lower maybe taking a shot in the dark at this ) so aftermarket springs might work very well with these dampers or if they release HFP ones

Likely... it seems that way with a lot of details on the SI since November

Si has a larger turbo (same as CR-V) for one difference. I believe the cams are different as well.

 

[JDM_DOHC_SiR]

I believe the cams are different as well.

Cams are the same part number on the Si for intake and exhaust as the other 1.5T engines.

Intake Cam: 14110-5PA-A00
Exhaust Cam: 14120-5AA-A00

 

[jbatman1080]

can we use these on normal civic EXT's?

 

[Curtman]

Does anyone know if the throttle body and intake manifold are the same parts for the SI?

 

[Mannyp93]

I want the front and rear sway bars for the SI for my EX. my car may be slow but it will be able to corner like nobody's business.
