Two hours of driving brings me in the Nürburg area of Germany, so keep those roads in mind when reading my build journal :-)



Introduction:

So I was looking for a fun weekend toy. Daily driver is a '17 BMW 330 so I am already quite happy regarding performance/quality and was looking for something that would offer me a complete different driving experience. After shortlisting four cars being 1) GT-R R33, 2) Cayman S, 3) Subaru BRZ and 4) 370z, the 370 won my heart with it's looks, V6 engine and revmatching function combined with quite a modern look and feel. I purchased a 6MT 370z and imported it from Germany last February to the Netherlands. A 2018 370z goes for 130k USD here (yes, thats GT-R money) so not many of them have been sold and they are quite rare.

As soon as I purchased the car I already had in mind increasing power levels, but I first wanted to make exactly sure that the car was aesthetically perfect and technically stable and well serviced.

First modifcations:

Exterior:

• Resprayed rear bumper: the PDC sensors have been removed but the job wasn't done professionally
• Resprayed rear trunk lid: i removed the rear screen wiper so got this cleaned and resprayed
• Resprayed door handles: I like a blacked out look and had the door handles resprayed to magnetic black
• Powdercoated the silver 19 inch Rays to NISMO anthracite
• Replaced the stock spoiler with a NISMO spoiler from thespoilercompany on eBay
• Tinted the windows to aid the blacked-out look

Interior:

• Had the steering rack modified in order to move the steering wheel +- 2,5" my way for a better driving position (i'm 6"3 but like the wheel close to me)
• Fit rear view camera kit: ordered, still need to install

Maintenance:

• Fitted new rear tires. I went with Hankook Evo S2 285/35/19

More horses
So with a lot of cosmetics done and having the car as I want it on the outside, it will be time to look into upgrading power.

My requirements:

• Needs to provide predictable power output
• Looking for around 425-450 wheel horsepower
• Dont want to open the block

For now I am doubting between 1) Topgunz SC kit, 2) Boosted performance single turbo, 3) A used GTM stage 1.5 kit
