I have close to $400 to spend. I am looking at either the 5/16" MD therm Spacer, Megan Resonated Test Pipes, 25mm V2 spacers around or a HKS Knock Off. I can pick 2 of these out of those choices except the exhaust. So which 2 do you think is the best?

I was leaning towards test pipes and V2 Spacers. I was thinking those 2 because it will give me the aggressive look with the wheels and won't be tucked anymore and then the test pipes to give me more of an aggressive sound. Then save to buy a better exhaust later down the road and the MD Spacer later.

Also do you guys think that 25mm up front will be to much or just right. I have an 03 Coupe on 18" OEM wheels and stock suspension.

I am also buying a Greddy front bumper soon.

EDIT: Here is my progress:


25mm Spacers Installed:









Ok so now I have installed my Tein Z H-Tech Springs:

 

I've got a set of brand new wheel adapters available for $160, that leaves you with $240 for your other mod


EDIT: oh and the 25mm's will definitely fit on the front with that setup

 

Don't waste your money on test pipes..

 

5/16 Plenum spacer. It looks like you did not have this in your list but JWT pop charger w/ z tube might be affordable in that budget. These two mods should cost around 400.

 

I have a Z/tube already, $20 local find 2 days after buying the G. Is there a way to just to get the pop charger? All I see are just full kits or should I just buy a Amsoil or equivalent drop in air filter.

So you say the MD Spacer over the test pipes and get some wheel spacers? I just want to make the right decision's and build my car right.

Edit: What about the power Lab's 3/8" spacer? Its just a lil bit bigger but no therm or copper option...I think and its about $60 cheaper. Whats your thoughts?

 

You have the tube and pop charger? Anyhow, md spacers and wheel spacers sounds like a plan. Its really up to you bro. You should get the things that you know would make your ride better in general.

 

no pop charger just the Z-tube

 

In that case get the pop charger, they are like a 100, and the plenum spacer should be like 200+. Again it is up to you want you want to get.

 

Waste??? I thought test pipes/hfcs freed up like 10 hp?

 

So what if I up my spending cash to $440

1. Kday's 25mm spacers a set of 4
2. Powerlab's 3/8" spacer
3. Megan Resonated Test Pipes

then later buy a worthy exhaust, pop charger in Sept and a tune later down the road. Does that sound like a good plan?

 

That's what I have been reading. I have read that the 2 best mods for performance on the cheap side is a plen spacer and replacing the stock cat's.

 

Keep hawaii beautiful, keep your cats!!

 

Begin rant:
I don't want to start anything but that statement comes from some one who use to have a TT G35 that would be more harmful to the environment that just replacing cats. Honestly we should make everywhere beautiful so you should be telling everyone they should sell all of there aftermarket parts to save the environment.
End Rant


Back on topic: so what does everyone else think of my plan?

 

I would probably replace the cat after you have gotten a good breathing exhaust system. Get the plenum spacer, since you have the z tube already, compliment it by getting the pop charger. If you decide to get the plenum and wheel spacers, that sound like a good plan too.

 

Haha, thanks for the entertaining reply. For some real advice, test pipes on a N/A car is pretty useless. If you really want to get some good air flow, get some High Flow Cats and a HKS Hi-power exhaust!

FYI: Plenum spacer + MREV 2 is dyno proven to be the best bang for the buck in terms of achieving some Horsepower
