I have $300 i am getting for xmas from my grandparents and want to put it into my G. I know its not much but i am debating between a front lip or either a Crawford Plenum or a Plenum Spacer. What do you guys thing i should get?

 

Well... ummm, what do you have done so far ?

 

all i have is Popcharger/Ztube combo.

 

How bout the spacer & test pipes for around $300. You'll feel the power gain right away.

 

Greddy Emanage best mod for NA cars

 

The way I look at it...
youre that much closer to purchase an exhaust

 

Do the Hotchkis TVS stage 1. Won't gain any hp, but you'll feel it on those turns.

 

+1 - I 100% agree...

 

which spacer to go with , the 1/2" or the 5/16", i really dont care about the engine cover and i have no strut bar.and i assume i should get the iso thermal?

 

Get the larger one-I would. The ISO thermal will costs more, and may keep you from getting the test-pipes. You may also want to look at AAM's spacer its relatively cheap.

 

what are some good test pipes that wont cause any CELs? I have heard of some people running lean or rich with test pipes, how can i avoid that? thanks

 

You cant avoid running lean, som ecu's compensate well for mods, most dont. If you get too lean you need a reflash or a piggyback later on. Any test-pipes work, I got cheapo mild steel ones that are rusted to $hit but who cars they arent leaking and they havent broken. If you throw a CEL, also with an 04.5' chancers are you will, you can get O2 sensor simulators to eliminate that light. Do a search for where to buy those....

 

how do you know if you are running too lean? will you feel some lack in power or will your car smell like a$$?

 

lean is hard to tell visual wise, unlike rich where detonating and smoke and smell of pure fuel. But if you are running lean you will notice in throttle response, The Emange is the best way for NA cars to get the perfect a/F ratio

 

if i can get the 1/2" iso thermal spacer or crawford cast plenum for the same price which one should i go for?

 

Do you own a helmet?

 

I have an 03 Z and installed the ims resonated test pipes and didnt have any cel problems at all. IT cost me 150 bucks.

 

I have the crawford plenum + Popcharger and love the combination. Right around 4K rpm you can feel more pull and hear a distinctive "roar".

 

if you are afraid of test pipes then get a y pipe, the stock exhaust flows pretty well, along with a plenum spacer. motordyne is having a sale right now.

besides they are both easy to install.
