Hey guys, I'm new a this I just recently got my '05 G coupe sitting stock as we speak. The only thing I've changed so far are the Rims. I got some Assanti 19in 3-pc wheels with 2.5 lip in front and 3.5 at back. But now I want to know were should I start, engine wise. Please give me Ideas so I can start getting parts. What would you think would be the perfect setup?

well i dont think i amma go FI atm so i'd recommend lil stuff first

grounding gear, intake, pulley, exhaust, plenum (spacer), etc...
you have MT or AT?

Yes, its an MT

For starters, since you have an MT . . . I would suggest Motordyne's new MREV mod. It has giving me great results. I think for the cost and gains, which you would recieve, that's a very good place to start.

you can always start off with a Z-tube.....

there is no "perfect set up", you try some mods and depending on the combo different results will yield. I would start will plenum or spacer, intake, exhaust, grounding wires, high flow cats, headers, cams, pulleys, and there are plenty more options

I have an 05 G too and I have high flow cats, plenum, and Injen intake and runnin 13.8's to 14.1's....

Get the MREV mod that Andy2434 suggested, apparently it's the newest mod for the g35 and it's supposed to be amazing.

there isnt any real good intake for 05, I dont know what you have and I dont think there is anything for 06 yet. MREV should be the best choice for starter.
