Hey guys, so I'd like to upgrade the intake / exhaust portions
Of my car and I don't want to buy more than I need for just
Average street use / cost for something that will actually make
A difference in helping the car breath better / possibly bettering
The vehicle in terms of long term life. I was on Aaron Cake's site and
He has two upgrades mentioned which are the k&n intake and
Bonez superflo cat. Will these two upgrades be sufficient in the
Terms I seek? Also, I'm not really into the k&n come filter replacing
The stock airbox bc in my opinion it looks cheap and ricey so I'll probably
Just get a k&n filter for the stock airbox. Would this option produce
Somewhat equal power as would the cone filter replacement? If I
Get the superflo cat I'll probably get the apex gt exhaust too, but if
I get those two parts should I get the racing beat street header?
I just don't want to have to mess with the air injection system. I'm
Not super knowledgeable about cars so bear with me.
Thanks for your feedback.

 

welcome to the board.

how far you go with the exhaust really comes down to whether or not you want to remain emissions compliant or not. you will also want to make sure your auxiliary ports remain functional. your budget will also be an issue.

that said, look into Racing Beat. they may not be king of the hill anymore in terms of outright performance, but you'll be hard-pressed to beat their quality. if performance is more your thing, check out Defined Autoworks.

 

Nice man, thanks for pointing me to Racing Beat, I like how they sell a full exhaust system all in one. In terms of HP gain would you know what I would get from a full exhaust system? I'd say about 20 prolly? And I heard a rotary engine works much like an air pump so expanding the intake / exhaust capabilities are your best options for a beginner?

 

full exhaust traditionally can yield anywhere from 10 to 20 percent increase, depending.

any engine is like an air pump in that regard. increasing flow through it (with enough fuel) will increase it's output.

 

When you say fuel does that mean bigger injectors? Or like a whole fuel management system? Which I don't even know what entails.

 

1in100 I highly recommend Racing Beat or Borla Exhuast, very "non-ricey" souds along side real gains in fuel economy and hp.

And when he says fuel he means bigger injectors and management system. Granted that all needs balance. So you don't want to just throw 1600 injectors on there straight out the gate haha. There's alot to learn man. Alot! It's unreal.

 

LOL, I'm not sure how much was edited by misterstyx69, but based on your post you know way more than most of the noobs who try to pretend like they know everything already.

Assuming that you don't need a cat, it sounds to me like your best bet is the complete Racing Beat exhaust because you can just bolt it on and not worry about aux ports, excessive noise, or piecing together something that may or may not work. If you do need a cat, then your original idea of a high-flow cat and cat-back exhaust would be best. However, the GT is too big for your non-turbo engine, which will result in more noise and less power. If you like the Apexi brand, then I would rather recommend the Apexi N1 Dual with the 90mm tips (not the 115mm tips). The Borla and Bonez catbacks mentioned earlier will work well too, and Racing Beat has a good catback. Stay away from the "turbo" exhaust components because the pipe will be too large for your engine, and the mufflers will not be sufficient for street driving unless you want everybody to hear you coming from 10 blocks away. The turbine wheel of the turbocharger soaks up about half of the engine noise, so turbo exhaust systems do not require the same noise attenuation as non-turbo systems.

The drop-in K&N filter and stock air box will be fine for your application. The rule of thumb is to not worry about the stock air box until 200bhp is exceeded. Your engine will not exceed 180bhp without porting the "block".

Fuel mods are not needed because the stock airflow meter will compensate for minor modifications, the stock fuel pump is good for about 200bhp, and the stock fuel injectors are good for about 250bhp. You can install a standalone engine management system (EMS) if you want a professional tuner to really tweak your engine, but the stock system is fine if you just want to keep things simple. However, I would check the EFI fuel lines on the engine and at the fuel tank to make sure they are in good shape. Also, keep in mind that the pulsation damper on these cars is prone to leaking, so at some point you may want to replace it with a new damper, or as an upgrade you can delete it and replace the stock fuel pressure regulator (FPR) with an aftermarket FPR that has a built-in damper (Aeromotive or SX brands). See this link on pulsation dampers:
Pulsation Dampers

 

That is probably some of the best non-turbo information I have ever read on this forum. The amount of invaluable information in that post cannot be overstated enough. People would save a lot of money and headaches if they read and applied this before they went and bolted anything they could find onto their car.

 

i'm not laughing at your question. i'm merely chuckling because you probably read a little too much into my "enough fuel" comment. really, all I doing was including fuel into the mix because technically, it would not be an engine without it. that's all. refer to what Evil Aviator said about injectors.

uh..COME Filter..!!!..edited!!!

 

Thanks for the info everybody, really appreciate your time and effort. And yeah I know "come filter" lol I saw it after I posted and immediately said to myself "maybe people will look past any perverted comments they could come up with" haha

Thanks again guys!
If I end up doing it I'll post pics. But right now I just want to get an idea. I think I'm gonna purchase the Haines repair manual so I can learn as much as I can about the car and how the engine works. Knowledge is power!

 

I picked up a racing beat street-able header (The one that goes to single collector), removed secondary resonator between cat and engine, punched the cat out, welded on a little extra pipe to attach to the header from where I removed the resonator and left the factory y pipe in the back. Added a K&N Filter, and routine maintenance.

This mod has made a great improvement for me, and it keeps Aux ports functional with the stupid pressure tube that goes back up. Sounds pretty good I think, Its fairly quiet until you go over 5k rpms, screams "sexy noises" at wot redline.

But this is all temporary for me, my Tii requires my wallet to stop being empty to get rebuilt

 

Just to add that Injectors are not "in your Vocabulary" until you go BIG..
When we talk an N/A with a Cone filter and aftermarket exhaust,then the thought of a 1500-2000 dollar ECU doesn't enter your head until you go over the Stock Max HP of the NA engine..
meaning.... Turbo Time ya'all!!!!..YEEEEHAAAAAAHHHHH!!!..Psssshh!

 

Haha your crazy, but I must agree ><

 

Upgrading your radiator is also not a bad idea. The stock cooling package is a little on the whimpy side. Koyorad or fluidyne make good ones.
