I need tourqe!
try the stock airbox back on. cone filter reduces the pressurized air, which is what's killing your "torque" off the line. my tacoma was the same, no torque with a "cold air intake"
i know you won't be happy since you just bought it, but, that's what e bay is for.
p.s.- if you keep modding your car your mileage will never improve. so keep the mods going! hehe

Did you take out the cat? Put it back!! Our little NA motors DO NOT LIKE wide open. I hate to shout, but there have been at least 6 threads exactly like this in the past three months. All the same problem, all the same solution.
You probably got talked into 2.5" or bigger on that catback, too, right.
It's all covered here ---> https://www.evolutionm.net/forums/sh...threadid=48382
Fair warning, it'll make your brain hurt
I think everybody involved in the discussion was taking ibuprofen by the bottle.

i was faster in the 1/4 mile by abuot .2 seconds with my cat on..then with no cat..but no cat definetly had better top end..and i also never did 1/4 stock..but with (header,intake,exhaust) my best has been 16.3 on stock tires( which are bald)
1) There is no reflash now.
2) Make sure your intake is good and open/large filter
3) Wires/grounding/plugs have NOTHING to do with improving your horsepower... what suddenly they make the fuel burn better or something? Yes they can improve your idle, and make for better response. But you will not see anything more than a 1hp maybe change.
4) No TEST PIPES... if you have it.. and your catback should be between 2.25 and 2.5"
5) Run REGULAR 87 octane fuel. It'll actually burn better in your engine. Higher octane does NOT have more power... only more resistance to detonation (spontaneous ignition). That will also help your fuel economy a fair amount.
6) If you are drag racing... uh well yeah.. no comment.. but if you really want to... rev the engine in neutral to 3K then pull into gear when you want to launch.. hard as hell on your tranny, but will give you the jump you are after.... also you can shift the transmission by using the different positions.
7) You can not pressurize air in the stock air box... only create a vaccum.. which means less air... which is NEVER better for your engine. The stock air box is ONLY a restriction. Some crappy CAI, or SRI's can be bad as the extra piping can be detrimental and you can somtimes suck in more hot air which is crappy too..
I think that's most of it.

When you get a bigger TB, you'll sacrifice TQ for bigger top end power?
Example.
Amongst SR20DET guys, few are using a Q45 100mm TB, which was designed for a V8.
You get TQ from header design and exhaust flowrate. Too small = bottleneck. Too big = sacrifice TQ for bigger bang on top.

So if the the TB won't give me any tourqe... is there any mod out there that will besides a turbo?
It's not all about maybe tourqe, but by getting these mods it is making me faster in a 1/4 mile (well should be) right?

sorry guys... 91 octane is not better UNLESS it specifically states that it has additives. Some of the gas stations put some additives in the top premium fuel that can be beneficial. Will you see more miles? nope.. will you see better mpg.. nope the opposite actually.. so yep.. just wastin money! Once you TC, or add compression, or start tuning by advancing timing etc.. then you need more octane.. octane is really only detonation prevention.
a turbo actually isnt going to necessarily help your low end, my jumps off the line SUCK, but once the turbo kicks in there it is, but i give up a lot off the line, as fo rmy low end, i have all the bolt ons, ALL of them, and when im not in boost i can say safely my low end is MUCH quicker than before, and you cant say its the turbo because i can drive around without boosting at all AND the air has an assload more piping to go through, so you will see much better low end with a throttle body and intake manifold, im not saying anyone is wrong, but it doesnt seem logical to compare a 4 banger to a v8 :\
Whoa, I have heard so true and some false statements here. First, 89 or higher octane is a waste unless your turbo, high compression or advanced timming. Buy low end do you mean 2500 rpm or taking off. A clutch isn't helping "low end", its just gonna grip better. Opening up the rest of your intake side (TB and manifold) will definately give you back some torque. Piggyback will gain some too. As for turbo, it depends on the size. A T-25 will spool quickly and give you low end, A t-4will give our small motor power way up top. Yes the parts you have will help your Quater mile times. I went from a stock 16.9 to (intake, header, testpipe, exhaust) a 16.2 and I think on a nice cold day I can break into the 15's.

start out with the piggyback, then work on intake mani and tb, after that theres not a whole lot to do unless you go tb or sc or even porting/polishing the engine along with balancing it all out
