MWR stage 1 cams 2zr-fe - Heads Up

[Jason@SportsCar]

It's infuriating that "bolt on" performance parts are almost never that. But you kind of have to deal with that since we are not exactly working on even remotely popular tuning cars. If it was a Honda or Miata 12 people would have already had that issue. Lol

Car should be getting fast with that power to weight. :)

I'm curious to see how the long tube header works out since it's intended for the Corolla. Hopefully no tunnel clearance issues. My DD is due for an exhaust replacement and I missed the boat on the xD long tube setup from RPM so this would be the next best/only option out there.

Ya unfortunately option are extremely limited for the 2zr. In my case I'm not too worried about fitment as I can take a hammer to my car if needed since it is just a track rat now. I'll make sure I post my experience on here for others so they know what they are in for if they purchase the header.

I'll post up a lap time sheet from the local YT guys Speed Academy to given you some idea if where the yaris sits in terms of lap times.

This isn't to flaunt my driver skill but as a way to show how capable the yaris truly is. It is really one of the few chassis around today that you can get below 2,000 lbs by stripping it down. I am amazed at how quick this car drops laps year after year compared to car that is has no business being anywhere near.

The yaris does however like to be over driven - bad for long multi lap races as it kills tires, but good for time attack style events

I understand how MWR wouldn't have come across the problem I experience earlier. But to not be honest with themselves and me that the sample size is so limited was BS. The one guy I was speaking (read: typing) with essentially acted as if there are a ton if people out there running their cams and no one has ever had an issue. As true as that may be, I bet I could count on two hands how many people are actually using their 2zr cams.

Based on my communication I clearly was someone who was comfortable taking a part and assembling an engine and properly setting up timing. They mentioned I could send them back on my dime and that they would cover the shipping only if they found something wrong with the way the cams were ground. It was always an undertone of assuming their product had no fault and the issue was all my doing with improper assembly.

Based on my situation, I would be out the money and they would be telling me I had made an assembly mistake somewhere even though they have no idea what.

I didn't trust them enough so I spent my own time to at least figure out exactly what the issue was. I'm glad I found it, but now they're using my time and expertise to problem solve their products as they come across new issues.

They also wouldn't tell me what the exact base diameter and lobe nose spec range was for their cams. They would only tell me mine "sounds about right" after I thoroughly measured them compared to my oem cams.

Had I sent my cores to them prior to installing their cams, I likely never would have figured out the issue. They send you a 2mm shim which is good for both the 1 and 2 stage cams. In reality that is much more shim then you would need and it is what caused a tenth of a mm too little clearance on my intake cam.

Like I said, it is what it is and we don't have options so we are stuck dealing w/ them if you want any 2zr engine components. My biggest qualm is that they are very short with you on communication, brief quick answers as if you are wasting their time. I've dealt w/ Carbotech, Gloc and other companies and they always seemed to be more than willing to have a full on convo with me and help me find the best solution for my set up based on their motorsports experience.

It just leaves a bad taste in my mouth, but at the end of the day I'll still be giving them my money. I wouldn't let my experience deter anyone from buying from them, they are a good company with good quality products. It just seems like they have one or two employees on the customer facing side that leave a lot to be desired in the communication department.
