Hi guys i just got a 2000 SiR full Stock. I just bought the AEM V2 Cold Air Intake (A MUST HAVE!!!!!) and was wondering what other things do you guys recommend for improving the performance on the car? Any suggestions welcome. thank you

best thing to do is get air into the engine and out just as fast, that being said, Intake/Headers/Exhaust.... a 2.5" exhaust and some nice headers will compliment the intake

I was looking into new header but which ones are the best: 4 - 1, 4 -2 -1, 2 piece or one piece? stainless steel or the (ceramic???) one. Also what brands are the best for headers, DC? thank you

welcome..

any chance of trading that V2 for one of the originals??
i've seen a few now that have gone for a shyt (brackets breaking off...)

dc headers are junk.. go with a vibrant SS.

The Prophet

you can spend lots on a header... so it depends on your budget... i am not really sure what headers are best and what are not but i am running a 4-2-1 stainless 1 piece..... not sure of the number differences between different types but most will give you a better flow regardless....

The Prophet

thats accually what im running, Vibrant SS 4-2-1 1 piece

How many k's on the car? Was all of the proper maintenance performed over the years?

Get a full tune-up, t-belt and waterpump, change the tranny fluid, coolent, brake and clutch fluid. Have the brakes and suspension components inspected for wear.

A decent header like many has suggested (brand depends on how much money you wish to spend, new or used) and go with 2.5" mandrel bent catback. I think Brad meant 2.5", not 2.25"?

Always do bolt-ons first, cause after that, you are really digging into the chassis/engine/body panel and most of the time, it is difficult to go back to stock.

hytech!!!!!!!!!!!!!!!!!!!!!

Hytech is definitely up there. Full Hytech exhaust system is even better!!!

Welcome to the B16A2 club!

Shlam that beotch!!!

I've parked my 2" lowered SiR beside sock height sir's and well....they look kinda high.....lol


And of course it improves you handling which is the main reason for springs...


Also all what they said^^ bolt-ons bolt-ons bolt-ons....

Enjoy your new baby! It's been the best car I've ever owned...

And....i've recorded from 32 up to 37 mpg this summer!!!!! So you'll love the fuel mileage even though it only takes premium...

VTEC ON!!!!

SiR b16a2

Welcome and enjoy your car

Yeah man i tried the 91 Octane from Shell the V power stuff it's alright. If you want to see true performance try the 94 Octane from Sunoco. Big Difference. lost about 30KM on a full tank for mileage.

imported_t_dot_SiR

i gain about 30km when i run sunoco octane 94.. and majority of the people here gains some mileage when they run octane 94

you're actually the first one i heard that lost about 30km when running 94. or did you mean the shell octane 91 made you lost 30km?

I have both the AEM V2 and DC Ceramic Header (4-2-1) on my car, and I've been pleased with the way they are. I've had them on for 3 years now approx. 100,000 km, and not 1 problem.

I would upgrade your ground terminal for your battery.

I changed mine out with a streetwires one since I was planning on installing a very decent sound system. Overall I noticed a bit of a difference in my lights being a bit brighter, the PW went down & up a bit faster, etc.

nope he is right,,,

on 94 octane you get worse gas mileage.. my SIR if lucky will get just shy of 400k's to a tank..

right now on 91 octane im recording 450k on avg...
nice car.. way to rock an SIR
