I call bullshit on docrace customer service. I cant get any replies via email, Instagram or even a phone call.

Fwiw i have been through 8 o2 sensors on the doc kit. Probably going on 9 when it gets reinstalled.

Doc Race has been pretty good at responding to me, but not always. I would say they are good but not great. I’ve ordered 3 kits from them so I have more experience than the average person probably.

Sorry to hear that man. How old is your kit because I'm aware doc has o2 issues but they claim they have remedied it , I also have purchased a couple kits from them so that may help as well

About 2 years i believe.

Yeah they send o2 extenders. Ive tried getting a set. Its not on their website, and they wont respond. I like the kit itself, but i refuse to reccomend it to any friends. I tell them bottom mount or if they want a top mount just go with on3. Save money. Upgrade turbo later when the on3 goes.

I have an MSD80 I no longer need if you want it. No idea what they go for but I'll sell it cheap. Got too much shit laying around and I'm going to start throwing stuff away here soon.


Thanks but I'm going to just swap over to he MSD81. No more worrying about blown mosfets

CES Kit all the way. I've beat the shit out of my car, the hardware is beautiful and holding up the abuse. 530whp @ 18psi on a GTX-3076R Gen II pretty effortlessly.

There's plenty of room down there. My tiny turbo could likely push close to 700whp on this setup. I think a 3582 would be perfect for anything north of 700. I believe they've seen 800+.

Hey whats your setup to make 530whp @ 18psi on the 3076r? I assume E85 or some form of higher octane? PI or Helix?

We are now developing a budget high quality single turbo twin scroll kit for N54. Will release it in the end of May.
