Engine ebay headers

ebay headers

on ebay there are two choices for headers, the obx and crome headers. Which 1 works best and has more power ^_^. thanx guys

The forza aka. obx header. Both the same thing. The chrome ones are just generic I think.

did u feel any difference when u slapped on the headers?

I'm in the process of installing them. I haven't had time since I've got finals. They'll be on in a week or so and I'll let you guys know.

dont use chrome, get a ceramic coating

Hey, rollatuner110, can you measure aftermarket header collector's diameter? I want to know what size it is. I think the stock is around 2".

need sum advice will a sri intake and a magnalfow cat back give me a 10% power up without headers??

haha, hell no. unless you got a really restricted setup on a V6 or something.

sure I'll measure it and get back to you after I get off work at 3 2mor

how much do i expect in an 1zzfe ??

well it depends if u have already an intake and exhaust system, if u have both it should kick it 2-5 hp, because of better flow. but if u just have an exhaust system, ur gonna get some lag because there is 2 much flow going out but not much air comming in. vise versa intake

I measured all 4 header tubes to be a constant average of 1.6 inches in diameter. The collector tube measures out to be 1.76 inches in diameter. The stock manifold must be really restrictive. I can't wait to install this.

Yes it will here is a dyno of my 05 corolla bone stock then adding the cosmo racing short ram and the magnaflow catback exhaust.
Stock 111.17whp & 110.74wtq
After adding the short ram & catback 120.60whp & 115.13wtq

The gain is still not quite exactly 10%. Squeezing as much hp from the motor naturally aspirated is tedious and expensive. If you want more significant power gains, go for a forced induction setup.

LOL that is pretty close there buddy it's 9.43% gains and that is not bad at all for 2 mods us 05 ppl don't have superchagers like the 03-04 ppl

get me more info on the headers wat brand are they?? i am in india and howmuch do they cost??

thanks a lot guys wish i had a dyno here in india how much does a dyno cost and how much do u guys pay for a reading might consider setting one up in bombay

That 9.43 is how much horsepower that was gained over stock like it shows in that dyno printout. 9.43 out of 111.17 is only 0.084825 or 8.48% gain. If you had a CAI you could get to the 10% mark but maybe not even that. Naturally aspirated power fights you every step of the way. btw the trd supercharger fits your car. Its us 1998-02 that have problems. You have enough hood clearance to fit that supercharger. Everything else is just tuning.

Wow buddy I dyno or cai and my short ram got more power out of the short ram thats why it's on my car. it takes less time for the air to flow into the intake manifold the the true cold air and by the time the air flows therw the cai intake it get worm anyways.

Well theoretically, the CAI is good for low end power since cool air is available right away. However, it isn't as effective for top end since the air has to travel farther to get to the motor. Like you said, the RAI is great for top end since its short and air gets to the motor fairly quicker, but as for low end power, its not as effective. <i>I</i> prefer the CAI since I drive around the city from stoplight to stoplight and need more low end. Power isn't always about horsepower. As mentioned in this <a href="http://vvti.net/forums/showthread.php?p=145347#post145347" target="_blank">thread</a> posted on this forum, horsepower is only a derivative of torque.

Wow! dyno for free! Good for you man! Dyno here is expensive, around CDN$100 for 3 pulls.

Only 1.76"? I'm kind of disappointed. The stock matrix header collector is around 2", 2000+ Celica GT is 2.25". I guess our 8th gen rolla is really sux.

I really have no clue how much they cost where i work i use there dyno for free.

It still makes a huge difference over stock! hehe
