G20.net: How, when & why did you first acquire your Infiniti G20?
gotboost44: I bought my p10 back in May of 2003 from some old lady that lived a few miles from me. At this time I was looking for a dependable daily driver that I could drive between home, school, and work. It was one of the best purchases I have ever made. I bought the car for $3,800 and it only had 54,000 miles on it. She also never drove the car in winter and it was immaculate.

G20.net: What were your original plans for the car and have they changed?
gotboost44: Originally my plans for the car where not anything special. My whole life I have been involved in one form of racing or another and the p10 was no more than a daily driver to me. I wanted to upgrade the stereo and throw a basic suspension and wheels on it and call it a day. Well needless to say those plans didn’t really change as much as I found it hard to stop after that. Next thing you know I’m doing a manual transmission swap and adding a fresh DET to the mix.

G20.net: What performance modifications have you made to your car?
gotboost44: Currently I have a W10 SR20DET with a GTiR T28 for a turbo. Im back to the stock high port cams again as I can’t seem to find an aftermarket cam I’m happy with for autocross. For the exhaust I have a hand built 3” turbo back system with a 36” resonator under the center of the car and a chambered muffler in the rear. For the intake I have the turbo hooked up to the Z32 MAF via 3.5” piping. Currently I’m only running 370cc injectors at 4 bar and I can put out more power than they can handle. The ECU control is a basic Calum tune that is fine tuned by my Emanage, Innovate motorsport wideband, and a Gizzmo electronic boost controller. The driveline consists of a b13 SER transmission that I hand built, and its all held up by Prothane engine mounts that I turned custom sleeves for. There are a lot of other little things I have done but the list would go on forever.

G20.net: Do you have any dyno numbers?
gotboost44: I have no recent dyno numbers that would reflect my current set up. But Since I have found the limit of the 370cc injectors at 4 bar I would have to say im right around 300hp the wheels. I have gone higher with boost with this set up (about 22psi) but the injectors where at 100% duty cycle and my engine started to lean out.

G20.net: What suspension modifications have you made to the car?
gotboost44: Currently I’m running Tein springs wrapped around GR-2 shocks. I have replaced my upper links stock bushings with a custom turned pivot shafts which sits in super pro bushings. In the rear I have installed an Addco sway bar. I have a couple sets of wheels to go along with it, I use a pair of 15” with Azenis for autocross and another set of 16” wheels for on the street.

G20.net: Any cosmetic modifications to the exterior?
gotboost44: Well I cut out the center bar in the front grill, debadged the car, carbon fiber hood, and sunroof delete. I have always liked the look of having more of a sleeper. The one mod that will be doing in the future though is adding a factory rear spoiler. I got the chance for the first time to follow my car as someone else drove it and I realized that the rear end looks pretty blah and its needs a little more spice.

G20.net: How about the interior?
gotboost44: Actually right before this I was running no interior. All I really had was the dash and door skins on. But with recent developments and me changing classes with autocross I had no choice but to put some of it back in, which I actually just finished up for the photo shoot. SCCA permits me to remove some items with my class so I don’t have A/C in the car, a radio, and the trunk has nothing in it. I have gained a new smaller steering wheel, racing seat, harness, and some gauges so I can watch my vitals at track days.

G20.net: Have you made any upgrades to the stock sound system?
gotboost44: I no longer have a stereo or speakers in the car. They have been replaced by a gauge cluster and some switches.

G20.net: Any future modifications we should look out for?
gotboost44: Engine wise I’m not going to do much more as the power is ridiculous as it is. I will be looking to slap on some bigger injectors and switching over to a newer Garret GT28 that has a roller bearing. I also might throw in some C series cams to rev higher. I will be redoing my entire suspension this next winter. I’m finding that at races I have reached the limit and it’s time to move to the next level. I will defiantly be installing an advanced adjustable coil over setup, but I have not made up my mind on exactly what yet. I will be upgrading my master cylinder to a 1” unit and run some different race pads. Also next year I will start to run A6 Hoosiers. And as some of you know I have a problem keeping transmissions in the car, so a B15 or p11 transmission is on the way.

G20.net: How and when did you first find G20.net?
gotboost44: I found G20.net when I first started to modify the suspension and stereo in the car a couple months after I bought it. However I really didn’t become a member until the power bug bit me in the butt.

G20.net: How has this site benefited you?
gotboost44: It has helped me with getting my project car done to where I like it as well as increase my general mechanical knowledge. It’s a place where I feel comfortable asking technical questions and actually getting an informative answer. G20.net also has served as a good way to kill time when I’m bored and/or don’t feel like working. Haha..
