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:
258274


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:
258284


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.
258286


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:
258300




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.

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

Very nice build and thread. What turbos are you considering? If not too powerhungry I can highly recommend EFR 6758 or 6958s. Very very good spool and will hit 1000+ crank horsepowers.

Thanks (y)

Originally I was for fitting an ETS kit with Garrett GTX2867R turbos but the seller couldn't get the turbos in a timescale that suited so I've let that idea go and now planning on EFR6758 in stock manifolds. The way it drives is key for me rather than a big power figure so hopefully the Borg Warner units hit the spot.

Another Black Friday come and went so I took advantage of the sales and the fact that my build still hasn't started yet.
I decided to get the last of the inlet parts that were on my shopping list and some other supporting mods.

265831

JCR inlet manifold

265832

265833

265834


AMS race intercooler. Decided on the 4.5" thick version so that the crash beam didn't have to be modified.

265835


AMS air oil separator to try and keep the inlet free of oil blow by. I figured that with the forged pistons that'll be going in that there may be more blow by than OEM pistons so this was a no brainer.

265836


GotBoost 3" chargepipes. I had the v band flange replaced (actually welded on top as the HKS flange fitted in/on it perfectly) with flanges for my HKS SSQV blow off valves and had them powder coated black.

Quaife front ATB type differential.


265838


Billet front differential housing

265839


PRL front differential bearing housing and air pump blank plates.

265840


Radium fuel rails and their fitting kit with FRP, lines and boost referenced fuel pulse dampers. This kit runs the rails in parallel (deadheaded) and gets rid of the restrictive OEM fuel transfer pipe at the front of the rails however I've got -8ORB to -8AN male fittings for the front of the rails and plan to order a fuel transfer hose from BMRS (Pro black DR specifically) and run the rails in series.

265841


HKS stopper head gaskets, exhaust manifold gaskets and exterior carbon parts for the front of the car.

I also picked up a rear wing from LM. It's nice bit of kit and well worth it just for blocking out the headlamps from the cars behind at night. Might have it refinished with gloss lacquer to match the HKS carbon or sell it on and order a gloss one from Mine's Japan.
265842


The fittings that come with the wing from LM were a bit underwhelming so these were replaced with countersunk screws and anodised orange washers. I also hated the silver cap nuts when I spotted them in the rearview mirror so these were replaced with 304 steel caps finished in black.
