The aim is simple, take this stock R34 GTT (aka Aby) and make it my own. Modified by me, for me. As of the 2017 Christmas period I have completed Stage 1 and 2 myself. During the the first 3 months of 2018 the final Stage 3 and 4 engine work has been carried out by RB Motorsport. This has turned this R34 GTT's engine into its Forged final form. With an increase of cylinder displacement, we have achieved a 2.6ltr RB25DET NEO. --- Tell us the story behind your ride. What made you pick this particular one? Where did you find it? * When i started looking for a new car project, the only car i had in mind was a Lowish Mileage stock Nismo/Altia Black R34 GTT. Having seen some of the dealer examples in the UK in the past and private sellers that had the very lack luster descriptions and rather suspect history's, i had zero confidence in finding a decent example anywhere in the UK that will be with minimal surprises close to home, that is if any ever popped up. With my final goal in mind for the project for both the Performance and the Aesthetics i could not risk serious mechanical issues hampering the project, I had to look further afield for a car i would be confident in, which lead me to the Skylines home....JAPAN. I used a company based here in the UK TorqueGT (but with representatives in Japan) to source the car, after many possible hits and disappointments, the Skyline was found. - Describe the modifications you've made. Where did you start, what’s the most recent mod and what motivated it? * The car has had a rather long list of changes since i collected her. Mostly split between engine work and suspension optimization. The best way to describe whats been done so far is the 'Stage' method i used. Stage 1 = Breathing and engine control, Stage 2 = Suspension optimization, weight reduction and Cooling, Stage 3 = Forged Rebuild and Clutch, Stage 4 = Increased power upgrade Stage 5 = Braking. Stage 1 was to get the car breathing right and cleaned up. Turbo back exhaust, Airflow, FMIC, Fueling, Boost control and Engine Management etc. Stage 2 was to get a set of adjustable suspension arms, bushes installed, remove the Hicas and weight removal. Cooling was aided by a bigger radiator and a carbon vented bonnet. Weight reduction by removing the Air-con system, spare wheel, jacking kit and the bonnet change. Stage 3 was when the build started to get very expensive. To allow for future modification and to future proof the engine to some extent, the engine needed to get forged, upgraded clutch and a full overhaul of belts, gaskets, idlers etc etc. CP, Tomei, HKS, Nismo, Splitfire to name a few include brands of parts included in the build. Stage 4 was included in the Stage 3 work to make the most of the down time and to finish the build a lot sooner, these included but not limited to a bigger turbo, R35GTR injectors, Tomei cams, 450lph fuel pump. Stage 5 is in the final stages of being organized, a K Sport 356mm Big Brake kit is on order for the front K Sport 330mm kit for the rear. - Of all the mods you’ve made, which do you think offers the biggest bang for the buck? * Two for sure. The first was removing the Hicas, that made a massive difference to how the car behaved on track and off' It feels so much more planted. The second and probably the best to be fair has been the Forging. To be able to have all the parts installed and working at there very best without the worry of anything critical going bang. For me, why install all the upgrades up to now, if i have to be gentle or run them at a lower efficiency so as not to stress them or the engine out, it seems a bit pointless. Peace of mind on that front is worth every penny. - How did you go about selecting the specific parts for this build? Any installation tips to share? * Probably about a 50/50 split between recommendations from owners and experience in working in the motor trade. The main method of selecting parts was always based on reliability and safety, branding and cost was a factor to a point but when i am building a car to be pushed relatively hard but also as a daily car/taxi for my family, they must be worth the price and if they are, money got spent. Most of the time i stuck to tried and tested Japanese brands like Tomei, HKS, Apexi, Greddy. But on parts like the coil packs, looms, spark plugs, filters etc, i went from my own experiences with them backed by owner club recommendation like Splitfire, Surefire, NGK or even OE equipment for filters etc. - Tips to share? Buy from a reputable company if you are buying Branded products, a lot of knock offs out there on Japanese brands. On engine critical components, always buy tried and tested branded or even decent owner club recommended brands, either is better than cheap budget no name brand parts. For critical engine performance components cheap or second hand is a big no no for me. - What’s been the biggest challenge with this build? * Keeping the car clean. Black cars are a nightmare! Other than that, electrical issues, plenty of them, but with most of the car rewired its hopefully a thing of the past. - What are you planning next? * The brake upgrade should be ready to fit in the summer, then a front mounted oil cooler when i have got 6000 miles and a few oil changes on the forged engine. Once that's done it may get a different set of coil-overs but the current ones are good enough for now. Then after that its a long break to enjoy the car as a daily, on road trips, get some track time and some car shows under its belt.
