Because race car.....

I forget this sometimes. I never plan on tracking this car though

I was right where you are about a year ago. But you posted in the right thread, I was kind of posting all over the place, hence this thread lol. But I also have an 03 5AT and I love it. I got bit by the mod bug so much that after I did things without research and ended up getting screwed. I payed over $800 for a shop to install and cold air intake only to fidn out it is one of the riskiest and useless things to do. I did the plenum spacer and resonating testpipes, and after that I decided to run a 75 shot of nitrous on a NX system. Very fun, but used in moderation, when I want to catch my buddy in his is300 turbo tuned to 390 hp. Like everyone said this forum has TONS of information, but I have had the most fun with going to G meets and talking to the guys one on one. Now I'm doing my wheels and and suspension. Good luck

Not gonna lie I'm a noob. I have a 1/2 thermal spacer by Motordyne and a oem z tube with a pop charge filter on the way. What are some good bolt on mods that I should look into next? I've been look at art pipes, injectors, uprev tuner.

bigger injectors arent needed unless you go F/I... ART pipes are a nice gain for the money.... mrev(if you have rev up), then a tune(dyno tune.....e-tunes are garbage)

Unfortunately I don't have the rev up motor just a plain 06 5AT g35 coupe. I read the thread at tony from Motordyne post a few years ago about the art pipes. The low rpm hp/tq gain would be great. I've also looked on the FS thread look at parts ppl put on their cars just so I do a little research and I found PMAS HPX MAF sensor. But I can't find any threads that explain what these aftermarket MAF sensors do for are g35

Aftermarket MAF's are for FI builds, you do not need them for merely bolt-ons.

Installed 1/2" thermal kit today and I must say the throttle Response is better. Not much of a difference in the sound but she'll get sideways pulling third in manual shift mode. LOVE IT!!!

Shouldnt have bought the pop charger. Its garbage

^And why is that?

Anyone using a Bullydog Triple Dog GT Gauge / Tuner -- Gas? I just stumble upon it.

I'd like to jump in and say I'm in a similar situation. I bought 04 6mt DG Coupe in mid March and love it so far! Just finding a good condition one with a clean history/black interior/6mt was difficult, and I had to have mine shipped from NY.
As this is a daily driver and heavy commuter car, the only mods I've done have been tint, wheels/tires, dark surrounding headlight tint(to get rid of the yellowing plastic), smoked side markers, a couple led light replacements, and a new Z-tube just last week. Roads in VA/MD are terrible, especially near my work in Baltimore so I don't plan on lowering it(plus I dislike lowered cars). I've also driven 14k+ miles in 4.5 months so no hardcore mods are in the future and I think I'm pretty much done. Maybe a painted front lip or a jump back to lighter Ray 19's, but otherwise just maintenance items are in the future.

Or an upgrade to an 07 or G37

Z-tube and pop charger installed last night tho the heat shield was no way near long enough. So I'm goin to fab my own. Sounds great with the new mods. Love the sound that is made when shifting though the gears on manual shift mode

It's not a bolt on but I wouldn't spend another penny until I got a transgo to help tighten the shifting. Night and day difference. Best mod I ever did to the AT.

I've looked into the VB upgrade yesterday but I also heard that with the Osiris tuner program you can adjust the 5AT. I also found a DIY project someone posted on here. Guy did a nice write up, do you have any pros and cons about the VB upgrade you done. Stillen also has a VB upgrade which they offer
