Love how clean / original this example is. But as you have found out it's a big responsibility to look after such a tidy original car.
Some time ago in 2010 I was looking at buying an FD Rx7 and weighing up pros and cons of getting a regular FD vs a Spirit R. I really wanted the Spirit R but then felt I couldn't modify it without decreasing it's value.
I did find a super rare Sunburst yellow Type RS-R but it had been hit up front and I shied away from buying it. In hindsight if I bought and repaired correctly it would likely be the only FD in Australia of its kind. So may have been a good "investment".
I don't have a GTR but a Stagea 260rs. I commented on your YouTube video and you guided me to this post. My Stagea had pod filters on it. But they were shagged and caused my AFMs to get dirty and car nearly stalled on me 1 night. So I put the stock airbox back on, but it totally muted the down low response feel of the car. I left it that way for a few months before I found a good Apexi twin pod kit and put it back on. Love the flutter noises and down low is so much more responsive feeling.
I can only imagine how the car would feel with a stock exhaust back on it. When I was looking at Stageas I drove a stock RS FOUR S with Rb25neo and it felt very slow. My RB26 car with boost turned up and 3 inch exhaust + pods feels so much more fun and powerful.
It really is hard to not modify these cars. I've got a couple of 240z's also and 1 has Triple 44 Mikunis on it. But another I found as a stock barn find car with auto box. It's so rare to find a good 240z these days and even harder to find them all stock! That I'm tempted to leave the auto box and keep it as a time capsule car.
Thing is the stock cars will bring the big money in future, since they will be so rare, but since getting the Stagea I've had a hankering for a GTR and find myself looking at the big HP builds more so than stock ones.
I feel it's the never ending battle between keeping these cars stock or modifying. They are so much easier to live with stock for regular driving, but so much more fun modified, it's good to have 1 of each like you do. But I'd find myself driving the modified slightly rougher car more often and probably enjoying it more.
Oh and for the family guys in here with kids. I highly recommend the Stagea. I bought mine as the GTR for the family man. I had my wife, 2 friends In the back and dog in the boot area of mine the other day. Perfect haha.
