Hi I’m from Los Angeles and recently purchased a project budget daily driver. A 2003 G35 Coupe auto. 3 weeks ago from Infiniti. It’s super clean condition 128k miles 2 Owners, clean title, completely stock.

Many have already told me I made a big mistake going with the 2003 with the DE motor. I know already I’m on a budget. As for the automatic option I recently bad 4 spine surgeries and 3 vertebrae replaced less than 1 ago had to learn to walk again so yeah no manuals quite yet.

I’m looking for best performance upgrade suggestions for more power upgrades for N/A build. So far I added new Apple play entire sound
system by alpine.

I have purchased had a few performance shops install a few parts:

New Spark Plugs and Coil Pack

Swift Springs (amazing handling running -2 camber all the way around)

New OEM shocks and controls arms (upper and lower)

LSD Swap

Full exhaust system 2.5” starting with Borla Headers+MR test pipes+high flow resonator and muffler delete

3” Cold air intake

Walbro 255

Bosche 550cc

Hiatachi 75mm TB with spacer

1/2” Plenum Spacer

19x9 By 19x10 ESR CR1 wheels with Hex caps

and a few other goodies I can’t seem to remember

order Intake manifold kit that includes upper/controller/lower by VQ Performance will install next week or so when it arrives

all work were professionally installed locally at performance shops automotive testing/church/unique auto sports

I just bought Tomei 266 pon cams with 10.8 lift. Fits stock 11m clearance. Looking for someone that can install in the next couples or days that does great work in the LA area for a great affordable price. I know it’s 10-13 hours all day job. Looking for a mechanic than can do it all in one day. Please send me message here and feel free to DM me Stayfitpeter on insta
