Hello
Love my G37x. Had it about 6mts now. Current upgrades are DC short ram intake, DC headers, proper cat delete kit, Nedivia cat back exhaust, stoptec calibers & lines, rotors & pads, Z1 oil catch can kit, Pedal Comander.
My questions are. Injectors 550 or 650 & brand? Fuel pump size & brand? Suspension coilovers or lowering springs? Upgrade the swaybars? Dyno & tune worth it? I don't have a AWD dyno or tuner near me there are ones a few hours away. Looking to improve preformance and possibly taking it to an open track day & test & tune at local strip.Considering SC or turbos later on don't have the extra $ for that right now.
Any & all help, info & suggestions will be greatly appreciated. MyG is extremely fun to dive now. I can feel & know it can become more. I've reached the point where I need help on what's next.
Thank you for all help

 

My suggestion is to upgrade the driver! Learn to drive your G better via a HPDE or autocross. Learn how to threshold brake and carve a late apex through a corner. Develop your ability to feel for the traction limit and how to maximize it. Push your ability to avoid accidents on the road with proper eye placement and reactions.

 

When modifying a car, don’t get too caught up in the destination as the journey is the really satisfying part.

Take your time. Start with exhaust since it’s a bottneck on our cars and delivers satisfaction almost immediately. Research exhaust setups, read some of the articles on Motordyne’s site about diameter and scavenging. Feel good about your decision, then rinse and repeat with the next mod.

If speed alone is your poison, buy a motorcycle as slow motorcycles are faster than most cars.

 

Lowering springs or coilovers, for sure. However that can be a slippery slope. Stance perfection is difficult, and personal, and expensive.

If in-person dyno tuning isn't in the cards, consider a remote tune process with a respected tuner. There are a bunch of them out there.

Swaybars... hell yes. It's not that expensive, and a relatively easy parts swap. The G37 responds very well to aftermarket sway bars, doesn't really matter the brand. However, once you start finding your car can handle better, that leads to a set of summer-only tires. And lowering your car. And getting LW wheels and brakes. Again, it's a slippery slope.

But yeah, get some swaybars.

 

No where in my post did I state my driving or racing experience or level. If would like to know. Here we go 30+yrs riding dirtbikes, atv's motorcycles & go carts, 2yrs in a junior dragster 35yrs street class drag racing, 2 yrs bracket racing. 10yr break from any type of racing due service in US Navy, Getting married starting a family & working to support my family. I've taught my 2 children to drive, my son to drag race, I helped teach 6 of 16 nieces & nephews learn drive and race. At 32 got into dirt track racing & mud pits & trail riding. As far as dirt track racing started out in fwd class and progressed to modified class until a work injury put me on disability and ended my competition racing days. I've helped build many race types of race cars trucks & bikes. Now that my kids are grown in college & out the house I've decided to have some fun. I've had 2 surgeries for my injuries. After 4yrs of therapy and pain management. I'm finely comfortable & able work on & maintain & do some fun not competitive driving. Use all the racing terms and techniques you need to make yourself feel superior. A Nissan magazine editor and chief should not be so ignorant, immature & unsecure of himself when answering a question from someone asking for advice, suggestions or help with a INFINITI/Nissan. My opinion
Thank you for your response I'm not interested what you think or the advice you offered.
P.S. Before you go acting like you do. I know my spelling, writing and grammar are incorrect and how it makes me look Why do you think I enlisted in the NAVY. I highly doubt you could or would be entrusted to maintain & operate muti billion/million dollar naval systems and equipment. My stupid sounding country boy was. I was working as department lead. When I was injured. I've done machine maintenance, been a trainer & a shift supervisor at multiple factories with different materials, machines and operations.

 

For somebody with a life story as rich as you claim, that was just nuts. There was zero reason for that snarky personal attack. None.

You need a time out. Your ban will be lifted on October 25 after 09:00 AM. I'll leave this thread open, so that maybe if or when you come back, you can apologize to dkmura and move on.

Welcome to the forum, OP. I hope things turn around for you.
