Looks like you still have the full setup of OEM vacuum hoses. If that is the case the VERY FIRST upgrade I would suggest is a vacuum hose reduction. Hopefully another member will provide a link. I switched to a new cell handset and my backup and subsequent download went as badly as espected so a ton of non app related info didn't make the transfer trip. And I've been too busy manuallylly transfer the data. It's on an external micro SD card. see sidebar below if comsidering a Moto RAZR FLIP handset.**
But there is a detailed guided instruction on the vacuum hose reduction and egr? delete on this site and stealth316.com (which if you haven't visited and bookmarked yet, you need to do so asap). I have both shortcuts to 3SI and Stealth316 on my home screen. Much of 317 site info applies to the gen1 platform. And I too own a 92 vr4, factory paint, Caracas red. Bought in 98 with 32k on odo, only add one until recently are some "vintage" Italian made 3 spoke chrome Antera Opus 1 rims/wheels 10x17. They widen the stance, which is cool imo, but the wheels extend beyond the vertical plane of the body which most dislike. Also had to add exhaust. So as 3" catless catback similar to tanabe or borla in look. That took out front pre cat so just had to gut the rear.
So after 20 years plus happy with it and OEM config, due to a click no start issue. The resolution of which has led me to the decision of going with a staged upgrade as they call it. Across the board stage 2 parts including larger turbos of course but a lot of fuel management and data logging hardware and software as well. Welcome to the site!
**2020 Motorola Razr Flip sidebar:
I was atypically drawn to this handset because my very first cell phone was a Motorola led flip phone, circa 2000...and I liked the unobtrusive size. From it I went to the very first Droid smart phone handset produced by Motorola, "chocolate bar" with slide out qwerty keyboard. 100% devoted to Motorola Droid phones through several generations. Then they sold out to Lenovo, and quality plummeted, an aggrevating fact that was compounded when phone issues significantly interfered during a family emergency. Pissed me off, I switched to Samsung (S9+). Then Moto reached back 20 years and added modern tech. Found MY weakness! And while I could do without the "we want to be buddy's with you so will push the latest cool features and advice" bs. I still did it. But the greatest blunder and single most inexcusable flaw and personal lapse in my not noticing, with the new Motorola Razr Flip phone (purposeful by design imo) is the absence of an external storage drive! Absolute bullshit play to gain unfettered access to my phone data. Would have been a deal breaker had I noticed that detail.
