Enthusiast Auto Care

We worked with Eugene twice in the last couple of months. One was a timing issue due to mileage and the other was transmission. He is the only shop we would take our Zs. He knows VQ engines thoroughly and has pride in what he does. The most important part for me was he was very punctual. The car runs great and it was fixed in no time. If you need care of your VQ engine vehicle. He is the shop for it. do not hesitate.

We were working on a 2007 350Z and it had an idle surging problem. Eugene was able to repair the engine control module. I am so happy we found Eugene. He was very efficient, knowledgeable, and the price was more than fair. He takes a lot of pride at what he does. Thanks again for all of your help!

Alright, so my Supercharged Z engine blew up. I contacted my tuner, let them know, then got ghosted. It makes you feel like you want to sell everything and never look back. This won't be about that though.

This will be about going supercharged, except, doing it right this time. Through the spectacular service that Eugene Turkov and his shop Enthusiast Auto Care has to offer.

Communication

My experience with tuners is that you call them, leave a voicemail, and wait for a reply, if at all. However, Eugene is the only one that picks up immediately or replies within the hour. Multiple times, Eugene was able to guide me through crucial concerns over the phone: switching from 91 to E85, diagnosing a fuel / exhaust leak, and addressing a check engine light denoting lean conditions. Just recently, I was having issues with my car turning off while driving. I texted Eugene and he promptly gave me a call to troubleshoot it over the phone. That same day, he was able to take my car in and fix the issue. A faulty MAP sensor.

Tuning Services

This supercharged Z is my daily driven vehicle, so I want to make sure that no issues occur during normal day-to-day driving. With Eugene's road tune, we were able to address knocking issues that occurred during red lights, stop signs, and in traffic. I assume that this would have gone unnoticed with a dyno tune. He also programed a flex-fuel option so that I could drive my car anywhere, without worry of what type of gas I need to put.

The car is primarily on E85. It starts without any issues, cold or hot. Driving feels as if stock during lower RPMs. However, you can truly feel instant power once you push the pedal in. And it's smooth. You can feel the boost rising as you go through higher RPMS. Considering the cars I raced, I should be in the high 400s to the low 500s, with the conservative tune.

I'm surprised people do not talk about his flames. I am throwing 1 to 3 foot long flames! When mentioning it, he said that he could stop them by adding code to the tune. Nah, I'm keeping them.

Mechanical Service

Eugene looked at every aspect of my car when I first brought it to his shop. He sent me pictures of slight precipitation in the supercharger fluid and oil, rodent damage, misplaced inner panels, repainted exterior and more. He also sent pictures to update me on the motor swap progress. It's been 6 months and 5k miles since the motor swap, and still no issues. The oil looks almost new. He pulled apart the blown engine and found bent rods which most likely occurred by turning off knock sensors.

California Laws

Alright, we all know that going supercharged in Cali is becoming more and more difficult. I want to thank Eugene for helping me acquire the proper documents for the car; from smog to VIN verification and the CARB legal paperwork associated with the Stillen supercharger. If you want absolutely no issues with Cali laws, see Eugene or look into his CARB legal twin turbo kit.

You can daily a Supercharged Z. You just need to make sure you have the right tuner.

*Test pipe modifcation was for track use only along with any custom tunes or builds.

My car before him was falling into limp mode and pulling timing on every pull. I made a post out of desperation for help. Eugene not only stepped in to help retune the car, but helped me diagnose and fix the problem. All from over 2000 miles away! He is truly the only reason my car runs.

He not only goes above and beyond what is expected, but he ensures you understand what he is doing and why. He's not only the best tuner in my opinion, but he's an outstanding individual that actually cares about his clients.

I would recommend Enthusiast Auto Care to anyone with a Z/G/GTR platform looking for a tune of any sort.

Gotta give a huge thank you to Eugene Turkov. He is extremely knowledgeable being a Nissan Master Technician and a genuinely nice guy. He didn't have to help me. I'm not a customer of his. I've never even spoke to him before.

As I was getting home on Thursday night. My Z basically shit itself. Barely ran. All I had to go on was a code p1093. Not a common code on Z's. He spoke with me for hours and with the help of him and the FSM he was pretty sure my VVEL actuator motor (that black motor on the back of the drivers side cylinder head) had died.

Today, not even 48 hours later, the car is back up and running great. Swapped in the motor off of another low mile Z and she fired right up.

Without him I would of been throwing probably thousands of dollars at the car spit balling what could of been the problem. With his help I did the right fix on the first try. With barely any down time for the car.

If y'all ever need a tune or general help with a vq issue i'd definitely recommend getting in contact with him.

Eugene,


Thank you for all the work you did for me.

My mother's last gift to me was a 2008 Infiniti G37s coupe. We had gotten it pre owned without much research into its history and of course it would start having problems. I drove it for years knowing in the back of my mind that it would need an engine replacement and I finally decided to a few months ago. I recently moved to Nevada but I knew that I still wanted to get my services from Eugene in northern California. Here are some of the best things about my experience:


1. Client education: Eugene went above and beyond to explain how different things works, what would be performed for the services, and what his recommendations were.

2. Communication: This was very important as I am currently living in Nevada. Eugene had my car for an extended period of time but he would always keep me updated with how the process was going, if there were any new issues, and on recommendations for parts that were being sold for a cheaper price.


3. Quality of service: Aside from the engine replacement, Eugene also helped me find the actual best engine, ordered all of the necessary parts, performed a full clutch service, helped me find an excellent deal on a set of wheels and tires, alignment and smog check, battery replacement, and probably many more small things I did not mention. My point is that Eugene does not only focus on the requested service; he addresses all of the needs that he believes would produce the best outcome.

I now have a beautiful 2008 G37s with a 2018 370z engine inside that I believe will last me many more years. I could not be happier.

Give Eugene a call- you will instantly see how he is different and why all of his clients love him.

I recently bought an Infiniti because my friend knows Eugene. I trust both of them enough to buy a preowned Infiniti. I felt much better knowing that my car is in good hands. Eugene knows exactly what he's doing and he's a stickler for perfection. He gave me a list of all the things my pre-owned car needed and got it done in a timely manner.

If you own an Infiniti, I highly recommend Eugene as your car doctor!

From the initial consultation, I could tell Eugene was honest and knowledgeable. He answered all of the questions I had and gave helpful advice regarding the work I needed done to my 370z. He was quick and efficient in doing the work I needed, updating me along the way. I will be coming back for any future work I need on my VQ.

I have been cruising the Infiniti G35 forums since 2010 and Eugene is well respected in the Infiniti/Nissan community due to his instructional videos and informative posts. So when I had a bad coolant leak, I knew exactly who I wanted to take my G35 to.

First off, Eugene is a great communicator. After sending him a message on yelp with pictures of the leaky hoses, he responded back in minutes and we were talking on the phone shortly after that. Second, with just the pictures, he was able to describe the exact fix and what tools would be needed, since I was thinking about doing it myself. When I decided to put it in an expert's hands instead, Eugene agreed to pick up my car in the South Bay and drive it back to his shop in Concord. He even has a loaner car, if needed.

While he was taking care of the coolant leak (replacement of coolant, heater hoses, radiator hoses, and thermostat), I decided to also take care of the following:
- Spark plug Replacement
- Throttle Body Cleaning
- Air Filter Replacement
- ECU Upgrade
- Rear Differential Oil and Bushings Replacement
- Brake Fluid Flush/Replacement
- Transmission Oil Replacement
- Power Steering Flush/Replacement

A side note about the throttle body cleaning: I read so many stories online about idle troubles after a throttle body cleaning, but when we encountered that same issue, Eugene already knew an ECU upgrade would solve the problem a majority of the time, which in my case it did.

On day one of the maintenance, I was there in-person and Eugene took the time to explain the repairs we were doing and why were doing them, which is way more than a normal dealership could offer. On the second day, I wasn't able to make it to the shop, but Eugene kept me informed with various pictures of the maintenance he was doing real-time. When all was done, we swapped cars in the South Bay, which was a total time saver. I'll definitely be bringing my Infiniti back to Eugene and I would recommend others to do the same.

Bottom Line: If you want quality work that's done right the first time, Eugene is your man.

HUGE shoutout to Eugene Turkov for my amazing tune. I need to start out by saying this is the most helpful, friendly, informative mechanic/tuner I have ever had the pleasure of talking to, the amount of information and knowledge gained from this experience is amazing. I was in need of a tuner as I purchased a fast intentions high flow cat and was having p2096 errors, knowing i ordered the fast intentions exhaust as well( should be delivered by the 23rd of this month) I knew I needed to have the car tuned so that its utilizing my new parts efficiently. Our first interaction was actually when he was on vacation, even out in the woods biking he was in constant communication and super helpful in educating me in what a remote NON-dyno tune is and how it will help me the overall performance of my car and why I should get the tune started now vs waiting until I had all the parts together. Not only did he give me more info than I ever thought about during that call, he also offered to back up my ecu so that if anything should ever go wrong we can flash it back ( not something most tuners will offer). Back up process was fairly simple, He shipped me a loaner ecu ( included the ecutek, ecutek stickers and a free ecutek t shirt) , once i got it i shipped him mine and he taught me how to do my first flash to the loaner.

Once I had my ecu we began to log my drives and have me log different scenarios ( 3rd/4th gear pulls, throttle pulls, mexico style driving , daily traffic etc...) to get my knocks removed and ignition timing perfected across all bands and in all scenarios. I would do runs /drive around town and upload my logs he would adjust accordingly have me reflash and have me do more runs and logs.

The most impressive part is actually the education. I've learned more than I ever wanted to learn and I'm thankful for it. I can now read my logs and know exactly was being adjusted and locate knocks and improper timing and how to properly use the ecutek graphs to compare different variables. I would look at logs and send him screenshots to confirm what I was seeing and he would educate me right there and even expand on what I was asking. I've learned what AFR is, knock, detonation, ignition timing and so much more.

After about 2.5GB of logs ( 17 tunes) did we finally get it to where its perfect. At this moment we will just be doing maintaince/ seasonal tunes to make sure my car is optimal all year around.

Compared to stock I can say this car is 100% different in response, I press the gas and I just go there's no revving, no huge rpm spike then drop. When I'm cutting and weaving through traffic I swear it's like I'm a hot butter knife and the butter just gets out of my way..i can drive break and reaccerlate without any hesitation or lag. It just does what I want it to. Stock was annoyingly slow and boring to drive. It's super smooth now and oddly scary how easy it is for me to hit high speeds without even knowing.

He can give you different maps and features for flames and what not ( I opted out. I'll leave that to the kids) if you would like. There are plenty of videos of his tunes shooting flames on par with Elon musk's flamethrower.

I know people will ask for the dyno graph, but I'll get it on a dyno once I can find a awd dyno in houston ( I'm not disabling features to turn it into rwd, I got a awd I want a awd dyno) or have time for a 3 hour drive to killeen (or motorsports)to get it done. I'm for sure hitting @krmotorsports at the end of the month to get offical numbers once the full cat back exhaust is installed.

Treat yourself and your car to a eugene tune you will definitely learn something and your car will ride better at all bands guaranteed. I couldnt be happier
