The Kit:
First off, the build quality is great! As many of you have seen, the welds are incredible. The installation is pretty straight forward and if i were to do it again, i could do in less than half the time. I did run into one problem during the install that was my fault, which brings me to my next topic.
The customer service!!!
During the install I installed a check valve oil fitting backwards. I didnt realize that the turbo was not getting oil and i ran the car like this for about 20-30 minutes just idleing and cruising around my house checking for anything loose with the install. I never went into boost or anything like that. It wasnt until i took the turbo reservoir down and no oil came out, that i realized the turbo wasnt getting oil. I contacted Sasha and told him what had happened (in the instructions i received there wasnt any clear pics/instructions how to assemble the oil fittings. But it was still my fault for messing it up). He assured me that he would take care of me. By the way, I PMed this guy so many times, i upgraded to the premeir membership so i didnt have to keep erasing my box. LOL. He answered my PM's like they were txt messages, it was crazy. I brought it to get tuned and halfway through the dyno session, my tuner told me he thought something was wrong with the turbo because it was smoking more and more. I stopped and brought the car home. Sasha told me to take the turbo down and send it to Precision. By this time, i had the turbo out in 20 minutes! not kidding. It takes longer for me to jack the car up and get it to the right height on jack stands than to take my turbo down! The turbo was ruined and had to be repaired by Precision. Sasha pmed me and asked if i would pay half!! I couldn't beleive it. Talk about customer service, i mess the install up, damage the turbo and i only have to pay have the cost? Imagine if i had a Greddy kit and called them to let them know i messed up the install and was wondering if they could help me out!? So now i received the turbo back and everything is ready to go.
Tune/Results:
I decided to go with Dent Sport Garage for my Uprev tune. These guys were awesome. They went out of their way to help me and i couldnt have been happier. My tuner, Matt, told me that if i was looking for big numbers, i came to the wrong place. He was telling me stock evo's and sti's normally put down 215whp stock. There was someone in the Tuning section here that went here and had a bolt on Z and dynoed 220whp and after a tune like 24x whp, so it reads fairly low. But as we all know it is just a tool for tuning and there are a bunch of variables. I told my tuner i wanted the tune to be very conservative. I had it tuned at 10 lbs of boost.
The Results: 404 HP and 359 TQ (it made 408 on one run but this was the final run) on a Dyno Dynamics Dyno
It saids a 2004 G35 but he just forgot to change the title. keep in mind this is a really conservative tune. Low 11 AFR's and only 8 degrees timing at peak TQ and 14 degrees timing at peak HP.
Overall i am very happy with the kit. The car pulls so nice in the high rpms, its like a totally different car! If anyone is on the fence about this kit, trust me its worth it. Its great for a DIYer and you learn a lot about your car and the kit after going through the whole install. Heres a couple of pics that i took of the kit.
