My 2500 mile review:

Pros:
Super easy install. Exhaust/down-pipe is very nice and fits great. Lars's exhaust tips are beautifully utilitarian. Perfect combination of quiet, lower pitch exhaust and ricey BOV noise (I am serious). Car took on daily driver duty 1 day after first start and has had 0 issues related to the kit so far. I need more projects where I just hand some guy in Virginia a small pile of money and then bolt a bunch of parts to my car 3 months later, and less where I try to make things in my tiny garage with a grinder and my MIG welder.

Cons:
I never got a sticker. I reported Lars to the Better Business Bureau.

I *think* my turbo failed today. There's not really any shaft play, but I need to remove it to investigate further. Ordered a new one already because I need it before next weekend. Hoping it was a fluke, as it was on the 4th autocross event with it...

Anyone know of a watercooled turbo that will drop into Lar's stuff?

Yay, it's not the turbo. It's the BOV. It's not closing until it builds 2-3psi of boost. After that it's fine. Took it all apart and cleaned the **** out of it. Still not closing. Tried putting one of the washers in, didn't fix it. Will experiment with more tomorrow.

Just wanted to put in a good word about Lars' customer service.

I got a kit from him almost 1 year ago this month. It took me a few months to get a few other things for the build ... intercooler, injectors, MS3x and find the time to start on the installation. I think it was October when I finally got started. I had many questions and Lars was very responsive and took time to answer them all. In November I broke the **** out of my wrist at the skatepark and have been out of commission until recently.

Last weekend I finished the install and loaded up a base tune to get the car started. It started right up, though it was running very rich. Had some issues with idle (would shoot up to 3k and stay for a while). During that time, I would hear the turbo making a scraping noise as it spooled down after I shut the car off. Took a closer look and there was considerable shaft play (not the good kind lol).

I contacted Lars and sent him a video and pictures ... he said he will take care of it. Now .. it's been about a year since I bought it ... so I was very happy to hear that!

Yesterday he dropped-off a new turbo along with a set of gaskets. At his expense.

Being a small business owner myself, I know that things can go wrong now and then. What sets you apart is how you respond to issues and problems. Have we always made everyone happy? No .. but we make every effort to fix a problem and that is one of the reasons we have stayed in business.

Cats awarded for how Lars handled this issue! I have and still would recommend MKTurbo to anyone looking to get a decent kit together at a good price.

Seems to be leaking oil from here. Before this the drain line below was leaking right where the ntp fitting screws into the turbo. I took it out and reinstalled making sure it was as straight as possible to the oil pan. Then after that I reinstalled with some thread tape just to make sure. Hasn't leaked there again. Couple of weeks later and it's now leaking from here.

What do you guys think? Failing gasket? Failing turbo? Or failing me?

P.S. the oil restrictor is installed

IIRC the turbo has a NPT thread under the flange. You could just install a fitting in it and eliminate the flange altogether. I used a Vibrant restrictor with an NPT to AN4. Much cleaner and no leaks.

EDIT: spelling...

I quit using the aluminum adapter flange because always ended up leaking on me. I went with the adapter screwed into the CHRA threads and never looked back.

Anyone have a link to the parts to buy to change over to the better setup by chance? I'll be looking to do the same thing for my setup.

Here you go. 1/8NPT and whichever AN size you need: Oil Restrictor Fitting Kit - 10288 or 10289

Paging: shuiend!

Lars, been trying to get in touch with you. You said you'd send the air filter that was meant to be included in the full MKTurbo kit I purchased back in August 2017. I've reached out via email a few times but never heard anything back. Can you give me a ping and can we set something up? Been almost a full year bud. I just want my car to go choo-choo.

Thanks,
Dylan

You've waited a year to run your car due to an air filter?! Lol

Haha not quite, it wasnít the factor that was holding me up. Lack of time and money (specifically for a replacement clutch) has kept me from doing the job, but Iím finally ready. Oh and my car is a 1994, which in Atlanta Georgia no longer requires emissions (25 years old), which was another factor that caused me to wait.

Just been trying to get in touch with Lars for a few months about the air filter. I get what other people say about his good customer service but I feel like heís ghosted me at this point.

Quick update:
Lars got in touch and heís sending over an air filter, and it seems the original one got lost in the mail somewhere. Great guy!

also, for cpierr03 and Junkythecat, and anyone else who may need to get in touch with Lars, I may have a peak behind the curtain for you. He mentioned that he usually archives email threads once theyíre closed out, so the easiest way to get back to the top of his inbox is to send him a new email, not part of an existing chain. So hopefully thatís useful to know.

thanks for reaching out Lars! Canít wait to start blasting!

Thanks for the update. Nice to see the issue handled properly. One question... I just installed an OE replacement Exedy clutch on my 2004LS. The car is a commuter/weekend fun toy, and I do keep the hooning to a minimum. If I were looking to install this setup, how soon will I be looking at doing another clutch job?

Immediately. Stock Miata clutch won't hold much.
