06-08 SI's what ya need to hit 13's

[Antz97znj]

Fbody guy here, have owned several LT1's and a LS1...need something better on gas plus i think the new si look good...what kinda mods do u need to break into the 13's.

[ErichPryde]

a 100 shot of nitrous should get you there fairly quickly. otherwise, an intake/header/exhaust + reflash & sticky tires combination should get you very, very close to your goal.

short of things like this, blowing the car is a great (albeit very expensive) way to break into the 13s.

[jonesthewine]

forced induction and driving skilz...

or disregard for the powertrain (powershifting) along with intake/header/exhaust upgrades.

[ErichPryde]

oh, and by the way- welcome to 8thcivic.

the bolt-ons and all motor forum should have a lot more info to help you out if you look around in it.

[Antz97znj]

How about na guys lol...fi might take awhile and im not a nos guy

[ryryninja]

Atleast I/H/E sticky tires and also lighter wheels. Not to mention some driver skill.

Welcome to the 8th!

some people have gotten very close stock... bolt-ons, reflash, and good driving will get you there.

a member on here (i think bboy bust) ran a 13.9 with a BCRH and CAI... everything else on it was stock.

you should also look into the factory underspoilers... they make the si look alot more attractive imo

I already did, I went and built one over on the honda site.. I think the front piece is all i would get though. So as far as first mods I was thinking cai, catback, and throttle body spacers. What do ya guys think? Ive been strictly a muscle car guys here w/ the rare evo site visit so any advice would be appreciated. Gas prices are getting to insane for v8's. Being in jersey I need to stay emmisons legal too.

there are differences in each model year that are fairly significant. In 2007 Honda added a Traction Control System (TCS, but Honda calls it a Vehicle Stability Assist system (or VSA for short) as Shark Tek pointed out)) to the Si that will kill throttle power when it detects lack of traction. this feature can (thankfully) be turned on and off. In 2008 Honda added a Tire Pressure Monitoring System in addition to the TCS.

You forgot the vehicle stability assist (VSA) added to the 2007 model.

[ErichPryde]

when I said TCS, that's what I meant. thanks for the correction.

Almost the same concept as building muscle cars (bolt ons, internals, and reflash) how to do it is where it differs. Also consider Weight to power ratio.

is it 50 state legal?

[anavrin351]

No.

People are also putting k24 bottom ends on the K20Z3 (SI motor) top end. I ddnt read a whole lot about it or see any numbers, but the torque increase is supposed to be very good. You will miss torque in an SI coming from muscle cars, but high reving is more fun to me

[RedLineSi]

Intake / Raceheader / Exhaust plus good tires and driving skill..

[ErichPryde]

if you're going to do something like that, you could always stroke the car.


if you want it to be 50 state legal, you could go for the Hi-flow cat and shorty header combination. although I think using ANYTHING except the stock cat actually might get you in trouble in cali...
