Definitely contact Topgunz about purchasing the A2A air to air intercooler set up or make plans to install a air to air intercooler set up it’s a much better choice as the air to water set up is inefficient. Since you are located in Northern CA look into Z Car Garage as they are not too far from you. You should speak with your tuner to see what tuning software they use and recommend. ECUTek tuning would be my first choice.

Yeah, I've been talking to Rob @ Z Car Garage. He did my suspension.

It sounds like an aftermarket tune is desirable regardless, which is kind of a shame from a technically legal standpoint, but it doesn't sound like California smog checks require validating the tune. I've read horror stories from other states rejecting tunes.

Now you need to get a Hotchkis front sway bar.

Are they better than the stock nismo sway bars?

Definitely. Most guys just update the front bar and keep the stock rear bar. There are a few threads on here about the Hotchkis sway bar.

Do those guys track all the time or just overheat in street races?

Overheat in street races and mountain driving. We have a hot summer here. I'd suggest you go 34 so that you won't need to do it again in the future.

As for the sway bars the best advice here would be to do a search and purchase the sway bar/s that best match how you plan on running your Z. Also depending on your climate and what your goals are with your Z I have seen a lot of guys get away with doing a 25 row oil cooler but, don’t be afraid to go bigger on the oil cooler is what a lot of the people here will tell you 34+ row oil cooler if you plan to track your Z.

Hey guys just wanted to let everyone know that the EAC twin turbo kit for the VQ37 has received carb approval as of March 6th, 2023. The kit is now another option for those seeking to boost their 3.7 in all 50 states. The carb number is D-873
