Engine 98 headers

98 headers

Which of these are the real OBX Racing ones or at least give a power gain?

the last one looks like it would. looks like a true 4-1 header. the rest look too restrictive. i would buy the last one and fabricate a 2.5" or 2.25" pipe to fit the collector with a high-flow cat. with emanage should give you around 140 atw = approx 160 hp engine

what cat would be good?

with hi flow catalic converter and hi flow resonator

this first one is the OBX header...the others are custom made....just ask the seller if he guarantees his product...you could be the 1st give us a review on it..

ok which one does anybody else vote for? ima get one in about 2 weeks

i suck at this exhaust thing, I need more low end so peeps give me a list off good exhausts to go with this header

the bottom one does not have lifetime warrenty the other two do

these wont give you low end. in fact you may loose a little but you will gain top end and higher rpms.

Found this Muffler to go with the header... ll looks like a fart can on crack, pcp, and x

the header wont work.....doesnt even face the right direction.... and as for the Tsudo exhaust....you can get it for $165 on ebay.......Thermal R&D and Alphawerks are good.

Low-End power is always going to be hard to gain.
Sadly, this is due to the fact that you do only have a 4-cylinder. Low RPM power is usually torque. And 4-cyls just don't have that much torque.

If you're looking for gains that'll make up for the lack of torque, FI is the way to go.

I've got 319 lbs of torque. But only 245 horsepower. I can romp on it...and it'll move ass up to about 50 mph. After 50, the horsepower takes over...and while it is still quick...it's not that fast. One of the reasons I'll end up going the turbo route myself in a couple years...it'll make up for my lack of top-end power.

the last pics(headers) looks more descent looking then the first pics(headers).if you want to save money go custom exhaust.

so I should go with this Header: http://cgi.ebay.com/OBX-Racing-Head...1QQihZ007QQcategoryZ33631QQrdZ1QQcmdZViewItem

and what muffler? and what to do about Reonator and catallic Converter?....

that 1 or the 3rd listing

the third one is not warrented so it is fake, What muffler you recommend? I kinda like the Twin loop OBX- Racing one

do not get that tsudo n1 it's retardedly huge. i bought one off of ebay. 4.5 inch tip is too huge for a corolla. and its super loud

go with the OBX Header cuz thats what I had on my corolla and I felt a good gain in high rpm's...Muffler, I wouldn't know what u should get...I had an ebay muffler an N1 muffler with a 4" tip and it was really loud. I had no cat and no resonator so thats why it was pretty loud. I liked that muffler c uz of the design but it was too loud tho. Just get a desent looking muffler kinda like the TRD one, and if u can, just get the TRD muffler!

which obx header is real? I found a nother brand of headers for ours from alphawerks

http://www.nexusindustry.com/ver03/index_frame.htm

go to the headers section and then go to toyota and it will be the last one but there is no picture... any good or what??? what do you guys think?

I hear alphawerks make some decent crap.. $435 that's pretty pricy.

alphawerks header cost $369 on importperformance.com

so is that a go for obx or go for alphawerks? I am a dumb @$$ when it comes to cars lol
I want the most power for my money whatever the cost but i need headers!!!! the exhaust manifold is restrictive even after I did the porting diy

Exhaust manifold still restrictive even after porting? Pretty hard to believe on a NA setup. The OEM exhaust manifold is pretty decent - not as good as a 4-1 setup - but for the cost (FREE vs a few hundred) - you would have the best cost ot power ratio with the OEM setup. I would try going with a decent catback setup or even just popping for a TRD muffler. Those have been shown to give some tangible gains.

If you are going to turbo next year - I'd save up the money otherwise spent on a header and extra piping and put it toward the turbo or even another car.

Spending $300+ on a header when you're going to be going turbo is a waste of money. Just put the money towards your turbo set-up(and spend a lot of time reading. newcelica.org has a great turbo FAQ).

what is the best upgrade to do? that does not affect whether or not I get a turbo?

Given some of the problems that you mentioned about your engine - that would be the first thing I would iron out

Also the Corolla takes suspension mods pretty well. You don't have to spend bankrolls of cash to get a decent handling Corolla - same goes for the brakes. Also a good time to get a good idea of what the baseline looks like - example would be a wideband O2 sensor and some sort of engine management. This way - you would learn a whole lot about what the engine is capable in stock form, fix any weaknesses in preparation for the turbo project - or tune the nuts off the car and extra the most from your current mods.

Anything that touches the engine directly (fuel, intake, exhaust) - I wouldn't spend any more money if I was to go forced induction. If your going to do it in stages - harder to say in that case. Then it would be what you feel like doing.

get a walbro fuel pump...emanage or other piggyback....exhaust system,..and bigger injectors not too big...

what size injectors are best?

link to the walbro fuel pump?

Just stick with the OEM ones for now. They actually can be driven to a much higher duty cycle (plenty of reserve) - and can keep up with almost anything short of a forced induction setup. At WOT, some people with wideband have seem them turn in an A/F ratio around 10:1 - mighty rich there. Can't just throw in any injectors - if you are running a N/A engine with large injectors without engine management - the car will run like $hit.

as long as he has the EManage with the injectors and was retuned I think he'd be fine......i have the 7mgte injectors sitting here with clips...

i am planning to go turbo eventually ( 2 years from now lol) im only 16 with no job atm got hired for a landscaping job the day I got up to go to work and got in my car and started it it wont budge without stalling out so I was fired basicly

It all depends on how much power you're looking for when you go turbo. Decide how much power you want, then buy things based on that. If you're going to be on low boost(6-8lbs) then 330cc-440cc injectors and stock pump would be alright, if you want more boost, some 630cc injectors and a 255lph walbro fuel pump would be needed. Maybe a return line and fuel pressure regulator too.

Things can be bought/installed in stages... clutch/flywheel, fuel/tuning, etc. Just do as much reading as you can between now and when you start buying stuff. http://www.newcelica.org/forums/showthread.php?t=199226
