Pls critique my noob performance mods.
Hey Scionites,
I'm ready to pull the trigger on some performance mods.
After plenty of searching through the forums. I've decided to pass on exterior cosmetics and put what I can into getting some zip outta my lawnmower of an engine.
Keep in mind that I'm poor so these mods fit my budget. Although if something is really bad I will consider spending more. Let me know if any of these mods are going to make my car sound like a tank tho...can't have it too loud...I like road trips and hearing myself think.
I just moved up to Norcal so I'm looking to go to one of these garages to get all this done once it arrives. 'cause I don't have tuner skillz like that.
Let me know your opinion on what's Cali legal if you know about that sort of stuff too....enuff of the blazayblah here's the stuff.
Okay. Here's what I got:
Megan Racing Scion xB 2004-Up Megan Racing Header
Agency Power Pulley - Crank Pulley
Tsudo xB N1 Axleback
Option Racing cold air intake
Here are the two garages I'm considering:
Griffin Motorwerke

Performance Options

Thanks for any and all advice. I'm ready to go....fast.

Intake's illegal too.
Of the things you listed, the header is the only thing that's really going to give you a bump of more than a couple HP. And again, the header is illegal in Cali... now, since the header is mounted on the back of the engine, it will probably be overlooked by all but the most observant law enforcement personnel.

Thx
Thx for the feedback fellas. Why do ppl even use the pulley if it's so detrimental.
So as it stands. NO header. NO Pulley.
This certainly will expand the exhaust budget.
I have a lot of hilly landscapes to traverse.
Any recommendations on CALI legal mods for Hps? Or should I just move.

People will do anything to improve their butt dyno numbers.
The pulley frees up a minute amount of horsepower and improves throttle response at the expense of unbalancing the crankshaft. Over time, this will destroy your crank bearings, and eventually your entire crankshaft.
P.S. I'm so against them because I'm paying $2100 right now for my ignorance about how they work.
It's what drives your pistons up and down. You wreck your crankshaft, your piston rods are next to go, and eventually you'll have a hole through your engine block.

ouch
Replacing the engine block sounds expensive. I'll pass on this mod then. It's the family car so I can't destroy it with bad tuner choices.
Thank you.
Okay so now that I have an extra ($300 bucks - minus the intake, the header, and the pulley) what kind of exhaust do you recommend. Hell, now I can get the rims.

i know lots of people with the crank pulleys on the tc's runing with them for a few yrs without any issues dont know about the xb though...according to what i read people dont have it on long enough to cause any real problems....im sure you can but theres the under drive puley and crank pulley....underdrive pulley is more dangerous then the crank pulley...i think any CAI for the scions are illegal just liike a modified exhasut and everything else we put on our cars..some states are stricter then others..

I've had my Agency pulley on my tC for years now with no problems -knocks on wood- But yea, could be different for xBs. If I had an xB though, I'd just get an axleback and spend the rest of the money on the exterior. A slammed xB with negative offset wheels is freakin sexxxy

I've had a light weight pulley on my car for probably over 40,000 miles. I haven't had any problems? I forget the manufacturer.
Also, for the parts you are talking about, I'm sure if you get in good with a car club up there the people will help you install them. That'll save you soem more money and you get a chance to do some hands on work and learn.

You can get an AEM CAI, and it is legal in cali for the xB.
Installing the CAI isn't bad at all.
Header and exaust is a garage job unless you got the tools and a lil know how. Both can be legal mods.
Check out some of the club meets and you will find help.
PM me for more info, Best of luck with the mods.

Tunergrrl, welcome to CALI.
Now, for an intake K&N Typhoon , it is CA legal
for a header , DC Sports is legal
for exhaust , anything goes for axel back , as long as it meets db requirement.
I live in Cali , in Officer Rosetti's town , have been pulled over by him for tail lite tint 
. Have these on my box and he never said a thing bout them ( he really knows what is legal right off the top of his head
)
So don't worry, there are a few mods that are legal in CALI.

Granted, I exacerbated the inherent problem in them with a full season of division-level autocrossing and HPDE's, but the problem with them still exists nonetheless.
