Welcome.
Test pipes give best bolt on gains.
full catback will help some.
tires. Sticky tires.
not much else beside tune and headers if pockets are deep.

 

Welcome... i have Berk tech HFCs and Ark Grip exhaust (sound is AMAZING) with the tekada intake, along with an Exedy stage 2 3 puck clutch and just dynoed at 321. So i am impressed with power and torque just from some simple bolt ons. Whatever you do, get a tune done by a good tuner. Send pics and info as you do your build.

 

Do you have another car to DD or is the G37 your only vehicle?

Cat-back, CAIs, testpipes, tune, tires. After that, power gets expensive. If you really want to race your X, FI + transmission build by Level10 in Jersey. Again, looking at a very expensive endeavor but you still aren't going to crack OKC SO's top 5 list lol. Check out L8tch's build thread (the black pearl) to get an understanding of what you'd be signing up for if you go the FI route.

I found it's best to look at the G37x as a jack of all trades but a master of none. It's a great car at just about every category but you aren't going to have a drag or track monster out of the box. If that's what you're looking for, I recommend you consider another platform or pick up a cheaper used car (a la G35/350Z) and build it for that specific purpose; as it would be a cheaper undertaking.

 

Primarily I want to welcome you and thank you for your service. My "nephew" is also in the Air Force currently stationed at Langley. Sadly, he is into the Detroit Muscle scene but I wont hold that against him... he's only 20.

There are plenty of decent folks here who are all very helpful. I am sure you will get tons of useful advice. Good luck with your build!

 

Best advice I can give, coming from 13 years in the USAF and USAFR, is to pick up a ~$2500 beater to drive around when you do more major mods to the G. I tried to daily drive my RX7s for so long and had so many issues with getting to work on time. I ended up moving back on base and using a bike as transport, which sucks in the rain, goretex or no, when my cars were all on jackstands. Bought a beater Accord for $600 (this was 1995) and then no more worries. You need to play the game of being in the military well first, then you can do more or less what you want.

 

 

Basic bolt-ons, tune, tires, suspension. Plenty there to keep you busy and with the addition of the suspension mods, the G would make a great track/auto cross toy.
