Here's my first ever build thread!
I've had a few modified cars since passing my test but never documented what's been done to them and whilst i'm a crap photographer and eloquence is definitely not my strong point, I figure I'd give it a go. So here goes. . .

Friday 13th July 2018 I took the plunge and bought my GTR. I traded in a W204 C63 for it and whilst the AMG was a great car I never really felt like I bonded with it. M156 engine is a masterpiece and sounded great but it kind of felt like you sat on it rather than in it and couldn't hide it weight when pressing on. It was also difficult to tinker with; opposite 'problem' with the GTR as you're spoiled for choice in regards to parts.

Here it was after getting it home:

It was left standard (come with a Miltek Y-pipe from Nissan) for a good few months whilst I got used to how it drove only adding a couple of little things. Import racing BMCS, bonnet dampers, Forge header tank, 316 undertray hardware and I added some sound deadening. It didn't really need the deadening but I had the stuff and I quite enjoy doing it so went for it regardless.

It made more of a difference than I thought it would. Covered the door skins and added some 10mm closed cell foam behind the door cards too. The boot is still to be done but that's the easiest bit to do.

Fast forward a few months to March 2019 and I managed to pick up a LM Superstock intercooler for a decent price. Fitted it in a few hours on the drive without any drama. Two people needed to remove the bumper without damaging the front wings but it's a simple job for anyone thinking about giving it a go themselves.

April road trip through the highlands :)

Fast forward to June 2019 and it was due a service. I did the man maths and figured i'd be more cost effective to have it tuned at the same time as the service (because reasons...) so, I did.
I called a few places in the UK and the best feeling I got was from ACSpeedtech. Andy had plenty of time to answer my many questions and didn't try and go for the hard sell so I went for it.
It got it's service and I had a few parts fitted:
ACS intakes with K&N filters
Speed density kit
LM AT Power 72mm throttle bodies
Ansu 1050cc injectors
And Ecutek v7 tune.
I decided against dowpipes at this time because I didn't want the noise, smell or MOT hassle and at this point of tune not needed.
Runs 1.35 bar boost and around 630/640 bhp if i recall correctly. It's pretty quick.

August 15th was my first ever track night. I was a bit nervous but I hadn't have been as it was great! Group of guys, mostly friends of friends, were all spot on and it was mostly fast BMWs with a couple of Mclarens, 911 Turbo and some more track focused cars.


The Datsun performed flawlessly. It got pretty hot quickly but I kept an eye on the temps and come in after a cool down lap each time the temps started to creep up high and the brakes didn't last as long as I thought they would before fading. I kind of feel I missed a trick because I never timed any of my laps! The guys there were lap time daft but It never even crossed my mind I was just enjoying the car and getting used to how it was on track. It was a great night and it even managed a solid 6mpg :-D

A few days later whilst washing the car I found lumps of Dunlop stuck to the wheels. Must've got a good amount of heat into them:

September/October 2019 I bought some more parts.
Fitted a 90mm GTC exhaust in September which was totally unnecessary but sounds nice and will be required later if (when) I decide to go for more power. Again, a really simple job to do yourself on the drive.

October I managed to pick up a new set of wheels. TE37 Ultras.
20x10 ET30 and 20x11 ET15 for the rear. Not the most aggressive fitment you can get on a GTR but I figured the 11J would meant less unsprung weight (not that i'd notice) but mostly meant I can get away with 305 rears rather than comedy sized tyres.

The R888r are coming off and going onto the OEM wheels when the Dunlops are done. On the TE37s I'm going to try the MPS4S. The wheels aren't seeing salt so not going on until spring time.

Black Friday come around so I bought more unnecessary parts that I talked myself into.
KW sleeve kit and a set of wrinkle finished HKS SSQVs. When fitting the SSQVs I decided to do some cosmetic engine work to so off come the inlet collector and upper boost pipes. I considered the Nismo engine cover (Nissan PN 14041-89S0A i think if anyone is after one) but went for a removable coating instead should I decide I wan't to change it again.





KWs are a good bit firmer than MY17 suspension but they won't shake out your fillings. They also allow corner balancing so that's why I went for them rather than the Eibach Pro kit. At this point I think full coilovers would be wasted on me.

And here's how the engine looks for now:

That's all for now. A good start.
Next up:
--- forged bottom end, some mild head work and new turbos (either hybrids or full frame). I've yet to decide who is going to do the work but I have 4 quotes to go over which is plenty to think about.
--- discs and pads better suited for track
--- MPS4S for the Rays
--- New silicone joiners for the TB > upper boost pipe
--- cosmetic exterior carbon

I was hoping to have the car in for a build this month but due to the current situation we're all facing, it's going to have to wait. But needs must.
I can still work on the car at home :)

I've been looking at supporting mods for the build. Intercooler I'm still on the fence about but hoping the LM Superstock will work for now. I've got my eye on a couple from the US- Sheepey racing and a Rampage fabrications core. Both get good reviews on GTRLife and are reasonably priced.

Today however (and following a trip to A&E last night due to super unleaded in the eyes...) I fitted a new fuel system.
The ANSU 1050cc injectors I have will be fine at the power levels I'm aiming for but the fuel pumps needed looked at. I was for getting drop ins and leaving it there but I managed to get a LM high flow 360 system delivered in less than 24 hours so went for that instead.


I also bought a license for EcuTek TCM. I was tired of the car laboring at low speeds and sometimes manual isn't welcome. Only driven a few miles on it but seems better than the MY17 TCM software even if its just holding 3rd a bit longer at town speeds.

I've avoided downpipes for as long as I can for a few reasons but now I actually need them; or will do when the new turbos go onto the built engine. I looked at a few options from various brands but settled on Russ Fellows. His work is ace, if you haven't seen it up close, you're in for a treat. He managed to get mind made and delivered within a week and I proceeded to wrap them in DEI titanium (just branding, not a chance at that price it'd have real live titanium in it!). I know it can be a controversial topic but for the heat management side of things and the potential performance gain, the reduced life of the downpipes is worth it. Russ told me he's only ever had one fail that's be wrapped and it was a bracket that needed re-welded and wasn't until they'd been on for approx 90k miles or something like that. When you see how well they're made and how thick the steel is you'll see why they last.

Next up- use the rest of the Dunlop RFs and fit my MPS4S to the TE37s/R888r to the OEM Rays.
