Designing and installing the turbo setup is one of the most enjoyable aspects of any build. There are many decisions to make when planning out a turbo setup and each decision has significant effects on subsequent decisions. It is a balancing act of desired goals and undeniable trade-offs. Many questions need to be answered like, am I looking to maximize mid-range response or top-end power? And, how much response will I be giving up if I choose one turbine housing A/R over another? These are questions that have different answers for every build. For this RX-7 we are trying to maximize response around a specific power limit without breaking the bank.
There has been silence in my garage for almost a year. The NX GTi-R, when you last saw it, had rod knock and was parked until I had the time to work on it. Life intervened and many things have caused this project to get pushed to the background. Then Mike Kojima and I met in the paddock at Buttonwillow. It was not that I was stalking him (well, maybe I was sort of stalking him) but a chance to meet the man after years of online chatting and emails was something I knew had to happen. After very few pleasantries the conversation moved to cars and then Mike asked about the NX. With his suggestions and input, my future build took a change of direction with my intended stock build moving to a built engine. Believe me, it did not take very much persuading to make this move. Eagle Rods, CP - Carillo Pistons, JWT cams, Calico Bearings, and a Precision Turbo. There is a plan for the NX GTi-R. I have not put this much money into the car since I bought it! The end result, however, should be spectacular. Version 1 - GA16DE with almost all bolt-on options. Version 2 - SR20DET with boost controller. And now for Version 3 - with a built engine, larger turbo, and eventually a stand-alone ECU.
In Part 1 of Project STurdteen we discussed some of the future plans of the car as a purpose-built entry-level drift car that can be used for competitive purposes in ProAm. One of the big issues I experienced previously had to do primarily with heating and cooling issues. We decided to go with a complete Koyorad cooling system, which incudes a radiator and oil cooler. We also included a power steering cooler to address steering pumping up issues \i had experienced in the past once the car would get hot, which is a common complaint in many drift cars.
After pouring over forums and websites the only company I kept seeing the words 'you won’t regret it' was with Fast Intentions. While there are others in this market that make a great product, it seems with exhausts you need to make the choice of compromising comfort in terms of interior noise for that last bit of horsepower.
Vince, our FNG, drives a Honda S2000 that serves as his daily driver. The S2K takes him to work and school day in and day out. However the Honda also serves as a track day vehicle seeing duty at Willow Springs, Buttonwillow and Cal Speedway. After serving reliably for 80,000 miles the clutch suddenly went out on Vince on his way to work.
We’re doing it people. The impossible is becoming possible. We’re taking a car that I don’t own or insure and slowly turning it into a track vehicle that is someone else’s day-to-day responsibility. That being said, in order to keep up this ruse, I can’t screw up its daily manners too much or the girlfriend might catch on to my plan. This was a big concern for me when I was planning one of the most important systems for the track, the brakes!
One of the reasons we bought a VehiCross, on top of its coolness, was the ability to tow another car. See, the VehiCross is not my only car. I have two others that are both in various states of disrepair and both are in Delaware, where I was born and raised. Currently, my two real projects are 650 miles from where I make my home in Kentucky and if I ever intend to drive these toys again I will need to get them here and get to wrenching. Now, we could hire a delivery service to pick up the cars and drag them down here, but that’s a) very expensive, and b) difficult since, while both cars start, they barely run. So we decided to do the towing ourselves. First we installed a hitch, then we hooked up a car.
A few years ago, this ridiculous trend swept the drifting community after the introduction of what us drifters call a “missile car”. During a track day a few months ago I was doing some tandem runs in my missile car and ended up getting hit after I spun out and went off course by the follow car.
If I hadn’t already proved it to you after Part 1, drifters destroy everything – side skirts, fenders, doors, bumpers, and more. Unlike other forms of racing, it isn’t necessarily about the lightest, most aerodynamic parts – it’s about the most durable parts! For that reason, I decided to go with KBD Body Kits, owned by parent company American Plastic Technologies.
It's been a long time between updates on Project Evo X GSR. It hasn't been for lack of trying, the car has been through a couple of different owners and it's been hard to catch up with it. Well we have caught up with it at last and it's time for some long awaited parts to go in.
It's a good thing too, Whiteline has come out with some new parts for the Evo X in the meanwhile. When the project was more active, the only parts available were swaybars but since then they have come out with a roll center and bump steer correction kit, a kit to reduce front lift and add positive caster, an adjustable camber link and a full bushing set.
As usual, racecars rarely get finished on schedule when you’ve got a day job, but that hasn’t stopped us from burning up weekends (and a little midnight oil on weeknights as well). When we last looked at the Polystrand CRX GT-Lite car, we had just finished creating the new rear framework for the trick IRS assembly. For those of you who haven’t been following the project so far, you can click here to catch up on the first 5 installments of this crazy journey. Without much fanfare, we’re going to jump right back in, since we’ve made a lot of progress since then.
