Now that my interior, exterior mods are done for now, I want to add a little more zip to the box. I'm not looking for anything ridiculous like a supercharger, but something more feasible, and not an insane amount to buy.
Thanks.

 

i would say new yellow top battery, grounding kit ,copasetor and um intake, cat back system, add a horse to the front that always works..... not much u can do to get big powere othere then turbo or supercharging it.

 

The cheapest... unbolt your exhaust from the axle, back... :D

 

A grounding kit will get rid of the annoying fluctuating RPMs at idle but don't provide any noticeable hp difference.

A cai will provide a lil more torque, and change the sound of your exhaust slightly, but don't expect too much.

An exhaust may free up a couple of ponies, but you won't notice anything.

With new headers and exhaust, you may feel a slight difference, but once you get used to it, you'll think that all it did was change the sound of your exhaust.

You may want to just put the $$ into other mods...

 

IF YOU WANT hp BUY ADIFFERENT CAR. Sorry fo rthe cps.
Even in gt4 the xb is crazy slow. but it sure does look good!!

 

^^ what the two peeps just said.. xcept for the buy a diff car.. xb rules.

 

In one of the magazine xB dyno tests, they dropped the exhaust at the axle and the car LOST 3 hp...

 

Well... it's still a 3 hp difference!! Gotta be worth something... Not everybody wants a 110hp beast. lol

 

Nexus's header (www.alphawerks.com) picks up 4hp at the wheels...thats about a 5% increase!

 

cheapest hp = nitrous.

the risk is yours

 

is nitrous counts as F/I??? or is it just a power cheater???

 

intake headers and exhaust will help good air in bad air out. N2O works great stick with a dry system and you should be just fine

 

just go for a intake, header, and catback exhaust system... thats prob around 120ish hp all for under 1000 (not including install price)

 

I'd say 12hp from intake, axle back, and header might be a little on the high side, but I think you got it covered by saying "120ish"

In all honesty, I'd expect to see ~8-12hp from these mods. A full 2" catback might get you closer to that +12hp range. Will you feel 12hp? Hell yes! You'd probably get a little better mpg, too.

 

injen short ram 4WHP, DC header 6-8WHP, good catback system 8 whp. from the numbers i have seen atleast, with a good catback system good intake and good header 20 hp to the wheels is definatly possible, so your looking at like 110-115 horse at the wheels with this car, hahahaha booo for the 1nz

 

d'oh! scratch that, then...

 

Listen I know the xB isn't a racer, I just would like a "little" more. Not 50 more ponies, but a few.

 

K&N's typhoon intake improves HP by 8.1 hp... which is MORE than a complete exhaust system will add (header, high flow cat, and catback) look at peoples dyno results... not much room for improvement over the stock exhaust other than making it louder.

 

That 8.1 horse in in accurate.

 

I have a 2000 Echo that runs the same motor, I have a open air filter, pulled out the baffle in the airbox, run 91 oct. gas, synthetic tranny oil, and I have run Mobil 1 Zero w-30 for 70,000 miles with no problems. The oil made the engine come alive!
