Just an FYI this is my first post I just joined like a month ago. Anyways, I have an 09 g37x coupe with almost every bolt on available. I'm making pretty good power now for an NA but like always, I want more. My list of mods now is test pipes, y pipe, cat-back, short ram intakes, m370 upper intake manifold, lightweight under drive crank and alternator pulleys, and an uprev tune. It's crazy fast compared to what it was before obviously but I always want more. Problem is I'm not sure what to do next so I wanted to get some opinions. I was thinking maybe 60 or 63mm throttle bodies and bigger intake tubes, lower intake manifold, or new gearing (which I'm not sure is possible on AWD). I also sometimes pull my AWD fuse and go rwd when racing, it makes a significant difference. I'm currently running 20" wheels that are heavy as **** and I'm working on getting a lighter set now, which I know is gonna make a huge difference. Anyways, give me your opinion on what I should do next.

 

What's your budget?

If you've got hella extra cash I vote for some fast intentions Long tube headers baby!! I put them on my vert and omg the sound and the gains are nyioce!!

If your budget isn't $1400 strong then I vote for a Takeda long tube CAI. This was my first mod and even after 15-20 mods later it's still one of my favorites. Improves the sound and the power instantly and doesn't require much work or time to install.

Let me know what you think! Btw nice work on tour bolt ons so far. Impressive.

 

CAI, LTH, 150 NOS shot, e85.

 

I'm with pongsanity on the 150 shot!!

How much would it cost to buy and install a 150 shot anyway guys??

 

Thanks for the input and the compliment man. ive heard mixed reviews about headers, I know theyre a bitch to install on our motors and I heard the gains were minimal and almost not even worth the trouble. Although I would love to hear the noises this beast would make with some long tubes on her. and yea I am definitely at some point going to replace my short ram intakes with a CAI, probably AAM, ive heard really good things about them. it requires you do some cutting but that's not that big of a deal. My budget unfortunately is somewhat tight at the moment so im not trying to drop 1400, preferably something around 500ish

 

my buddy is a mechanic and sent me an entire google doc with everything I would need to do a 100 shot on my car and ive thought about it but I just don't know how reliable the motor is gonna be after a few months with a nitrous setup on it. anyone have an idea on what the maintenance is like on a nitrous setup and what the long term effects on the car are? and yea im thinkin LTH are gonna be next most likely

 

NeverBoneStock did it from back in 2011 and had up until late 2015 because he's going boost. he had a nitrous express kit. another easy kit is the Zex kit.

NeverBoneStock build thread: https://www.myg37.com/forums/engine-...us-set-up.html

Nitrous Express kit: NISSAN / INFINITI DUAL NOZZLE (35-150HP) W/ 10LB BOTTLE

Zex kit: ZEX? '07-'09 Nissan 350Z Nitrous System

 

I was on that "not sure" about headers, pulled the trigger got retuned and pick up power every where. My thread from this past weekend is here. I would go headers and save $$$ for cams. I looking at those next

 

Carbor Fiber Driveshaft.

 

+1 for the carbon fiber driveshaft. lightweight flywheel, JWT cams.

 

Carbon fiber driveshaft? Who makes those?

I'm saving up for PNP Heads and JWT Cams. I also agree headers are not a waste of money!! Also Z1 Urethane Motor mounts. If you are RWD I'd also get the Z1 tranny mount.

 

i would love to have headers but the gains just dont justify the extreme cost and pain in the *** install. maybe someday when ive run out of NA mods available lol.

 

Im automatic so flywheel isnt an option, and can you swap to CF driveshafts on an AWD model?

 

yeah i guess 14+whp for 1200-1400 dollars isn't worth it!!
yet you gain less for a cat back system which usually cost more

 

Contact import parts pro for a quote on the driveshaft. U can contact pst driveshafts directly also. In a automatic G. I'd quicker save for a level 10 transmission upgrade. Headers would be perfect for a n/a build. There's also the pulley upgrades. Grounding kit. Ported lower intake. Get them all!
