Product Release! CorkSport Oil Catch Can Development and Release Notes

Sometimes projects take a lot longer than expected to get to release. After several design changes, lots of simulations, and plenty of mounting revisions, we are happy to announce the release the CorkSport Oil Catch Can for Mazda and Mazdaspeed vehicles.

Oil catch cans are designed to separate the water, oil and other contaminants from your PCV system. The PCV system feeds directly in the intake manifold causing all these contaminants to be pushed to the back of the valves then into the engine cylinders. As cars wear, we see more and more contaminants in the PCV system and then into the engine.

Many of you have followed the development as we moved through our design revisions beginning with our first concept, a titanium oil catch can that used stainless steel wool to separate out the oil and several versions in-between before we came to the design that we are happy to be releasing today.

Unlike other catch cans on the market that simply expect the contaminates to fall out of the PCV vapors, our newly released oil catch can has a unique cyclonic vacuum design that forces contaminants to the walls of the can before the air can move back into the intake system. This Solidworks simulation shows how the system was designed. You can see that the air swirls around the outside of the can trapping the contaminants at the wall. This allows them to fall through a disk that is welded between two chambers used to separate the PCV vapors and the contaminants. Once the contaminants are separated you can view them with a sight tube located on the side of the catch can.

We were particularly surprised to see how much water vapor builds up in the crank case of these cars. After a few miles of driving with the catch can on our shop Mazdaspeed 3, we could really see what separates our catch can from the competition. After only 500 miles we had separated out a great deal of contaminants from the PCV system. Most of which was water vapor that had been trapped in the PCV lines and engine block. This alone should ensure that oil doesn’t break down quickly on our DISI MZR engine.

After 3000 miles we performed our first oil change. The results were exactly what we expected, a much smaller concentration of water but a noticeable amount of oil. MZR engines are notorious for slight amounts of blow by getting back into the engine. As you can see from the picture this is something you don’t want getting back into your engine. We took this sample and sent it out for particulate analysis. The results really prove that you don’t want this in your engine. Along with a large amount of oil, which can be seen, there was metal and water present in the oil. All of which we don’t want to be reburned in our engine or stuck to the back of our valves.

Even though it took a little longer than we expected to release this, I’m sure everyone will agree that there are certain things you want done right and somethings are worth the wait. When it comes down to it there are just some contaminants that you never want entering your motor. Most of them are listed on the sheet to the right.

The CorkSport Oil Catch Can will enhance the reliability of your engine and improve performance and fuel economy. It is made from high-grade aluminum with a pressed annodized top cap and includes a chemical resistant sight tube. It comes with a complete mounting kit and can be purchased from CorkSport here.

Goodbye 323 GTX

Goodbye 323 GTX. Goodbye Cusco, GT Spec, Pedders, Autometer, Injen, Knightsports, KVR, RE-Amemiya, Mazdaspeed, and about 50 other product lines.

You may have noticed a recent news post announcing we are phasing out Mazda 323 GTX Parts. The 1988-89 GTX (in USA) was a great car for its time. Many owners have maintained and upgraded their cars to the point they are more powerful and better handling than some of the newest cars. A remarkable testament to the car considering it is over 20 years old!

Unfortunately, there just aren’t enough of them left on the road to justify further development and support. Sales have steadily declined for this car for many years. Ultimately, I think the recession was the last straw for us. Very limited inventory remains and we plan to remove this car from our catalog by the end of the year. To answer the most common question we’ve received since the official announcement last week: “Yes, a few parts will likely end up in our clearance sale”. To reflect on the most common comment we’ve received so far, “You Suck”; it is regrettable, truly. We don’t like it either, but it was ultimately our customers that made the decision for us.

We are also phasing out many product lines, as I mentioned earlier. Border, RE-Amemiya, Mazdaspeed, Knightsports, and FEED are venerable Japanese brands. They have always been slow movers for us, have long lead times for our customers, and sales volumes don’t support keeping parts in inventory. Japanese quality is exceptional, truly, and if you have the taste (and wallet) for these parts we are confident you’ll find a way to get them.

Brands like Injen, Centerforce, KVR, NGK, Unichip, Koyo, and Greddy have many products that are redundant to our own catalog. We are committed to making CorkSport parts the best value on the market but we don’t make everything. We’ve selected a few partners to fill out our product line. The remainders are being dropped from our catalog.

We’ll be launching a new approach to business early next year that builds upon our reputation for high quality parts at an excellent value and supported by the best customer service in the industry. This plan requires a commitment we cannot maintain while serving sales of other brand names. When you think “CS” will you think ‘customer service’ (pardon the lame humor)? We hope so.

There are no gimmicks here. We don’t trademark some odd spelling of a performance sounding words to trick you into believing your getting technology that is different from everything else out there. You are smart enough to recognize that sort of marketing. We could try gimmicks like free shipping but that means we inflate our prices to cover the cost (and thus it is not free to you) or we erode profits and have less opportunity to use them to serve you better. Better to know what you are paying for in my opinion.

Our goal is value. Price, quality, support before/during/after the sale, shipping, packaging, and warranty all go into the value equation. We are focusing our product line in order to offer better value to our customers through improved customer service and support.

Please send us your feedback. We promise to read and consider all of it.

Derrick’s Mazda Odyssey – How it All Began – Part 2

Continuing from the last blog post about my Mazda odyssey:

I was mentioning my impending transmission swap after I had destroyed the B6T AWD transmission, there where a few more bugs with the transmission swap and I worked them out over the next couple of weeks. The first time I took the 323 around a corner at high speed the car tried to trade ends. A quick counter steer and full throttle put the car into a very manageable slide. This is the way the car should have been delivered I remember thinking as I straightened the car out before the next corner. The 90-94 AWD transmission was setup to put more of the percentage of power to the rear wheels vs. the fronts.

I picked up some second hand Silverstone rally tires from the Tabor Rally Team to mount on an extra set of rims and try my luck at rally cross. The one thing you don’t expect to hear on an AWD car is “I didn’t have enough grip”. The combination of a small turbo which made instant boost which translates into instant torque and a 2600lb car made for lots of wheel spin even with rally tires.

As you can see in the picture above, the results were great! I think I exported about 60 lbs of dirt from the Hillsboro fairgrounds back home to Vancouver, WA after that event. It took forever to get the dirt and grass off the bottom of the car. I didn’t exactly set any record times driving that way but after a season of racing it was good enough for 3rd place in open class with the Oregon Rally Group.

There was another rally cross event which sticks with me due to the strange nature of the event. I showed up to the event with some shaved Toyo T1S tires on the 323. I didn’t have a chance to mount the rally wheels for the event. It was a good thing to, as the water truck was a no show. That meant no water to keep the dust down and make the course a muddy mess. My run group was in the afternoon so I got to watch the cars run in the first half of the day. After a while you could see black on the dirt from tires leaving rubber on the course. This was advantage for me with my Toyo tires. My first run out was one of the fastest on the dry grass/hard pack dirt and I placed fairly high overall for the day.

Around that time I was thinking, you know I could always use more power. So trying out different combos of parts like ECUs and air flow meters I finally settled on running an odd mix of parts. To get rid of the factory airflow meter I went with an HKS F-CON Pro unit that was not made for the 323GTX. This setup uses a pressure sensor connected directly to the intake manifold. It allows the removal the clunky air flow meter and allows you to run vent to atmosphere bypass valves. It also allows you to use a standard BP turbo ECU to run the other basic functions for the engine. A set of 550cc injectors are used with the system for when I decide to get something different for a turbocharger or I decide to go crazy with the power.

I was happy with the 323 until I ran across a set of Advan RC rally rims for sale in Japan. After several months waiting of them at arrive from Japan they showed up at my door. The bolt pattern was supposed to be 5×114.3 which was great. A set of Familia GTR 5 bolt hubs and brakes would do the trick for installation. It turns out the wheels I had received were 5×100 Subaru wheels. In the end this may have been for the better, Familia GTR 5 bolt knuckles and brakes are heavy. After weighing the units they are almost double the weight of the 4 bolt AWD knuckles. For a car that will see rally cross more often than high speed track events light weight rotating assemblies really make a difference. So what am I doing with a fancy set of seemingly useless Advan wheels now? I don’t let too many things get in my way that I want in regards to the 323. I have chased down a set of second hand hubs and I am going to drill them to 5×100 along with a set of rotors. I get to have my wheels and keep the lighter brakes.

Sweet JDM Wheels

This sums up my odyssey with my 323GTX. One thing that has remained constant through all of this is the BF chassis 323 shell. My car is now mid-way through the 200,000 mile mark. It has been in a few accidents, parked in a ditch by someone who didn’t know how to drive an AWD car, rally crossed, taken out on track days, drifted into curbs, and loved like a 323GTX should be.

Derrick’s Mazda Odyssey – How it All Began – Part 1

So when did you know you first wanted a Mazda?  I had my high school years skewered a bit by friends and other influences down the trail of Mazda ownership.  The first Mazda I really wanted was a 323 GTX.  Getting a ride to school in rain, snow, or any weather made me realize how unique the car was.  It didn’t help that the dual rear hatch wings and the decals down the side listing off the traits of a performance car “Full Time 4wd 16 Valve DOHC Turbo”.  I do remember seeing the 88 anniversary edition RX7s in white thinking they were cool but it didn’t have the pull the 323 GTX did.

It took 6 years before I got a chance to purchase a 323 GTX.  I found one in the back of an auto week magazine located in New Mexico.  The car was a 1988 model with no rust and had 132,000 miles on it.  After several phone calls and a generous loan from a friend I flew to New Mexico with a cashiers check for $3750 in my hand. I met the owner the airport in Albuquerque after spending a day in airports with short trips in the air at 3pm.  I drove the car to a nearby restaurant and took a look over the car.  It was a relatively stock car with the rear muffler removed for a bit more power and noise.  The interior was in good shape with no damage.  So we made the deal and I headed on my way back home to Washington State.

This being my first turbo car I did do some reading up on it.  I knew to let the car idle after driving hard for a period of time and to not stand on the gas until the car warmed up.  I had heard term turbo lag but never experienced it before.  About 3 minutes into driving the car to the freeway in Albuquerque I pulled out in between some cars to get onto the freeway.  Standing on the throttle at 1300 rpm and the car didn’t move to fast.  This whole experience stuck with me because of the large truck I had pulled out in front of that had to slow down because some fruit loop in a Mazda pulled out in front of him.  Thankfully my first run in with turbo lag ended with the car or the driver being unhurt.

The drive back to Washington was un-eventful.  The car was solid as could be and I averaged 24 miles per gallon driving through the night in Arizona and So cal to my first stop to rest.  After a night sleep I drove home the rest of the way and arrived in time for work on Monday morning.

My co-workers were pretty amused at the purchase I made.  I heard “you flew to New Mexico to get that?”  Apparently they did not have a good appreciation for fine automobiles that I did (ha-ha).

Skip ahead 4 years and the car had needs some love.   New turbocharger was installed on the car along with a refreshed cylinder head.  That was too much for the poor bottom end of the motor.  At 187,000 miles the piston rings had enough and I looked like the car James Bond with the smokescreen going full blast behind the car.  So at a crossroads of sorts I found myself wondering where to go with the car.  I had read up and seen the 90-94 323 turbo models from Japan and other markets.  Spending some time looking around I located an engine supplier who had a BPT turbo engine in stock.  After a week I had an engine sitting at home.  It took a few weeks to get the installation sorted out with the changes between the engines but I was back on the road with the BPT running on the B6T hardware.

One thing that was nice was the BPT made a lot more torque than the B6T engine.  It only took a year until the transmission let me know it did not care for the extra torque.  I had to get across the street quickly between the flows of cars in downtown Portland.  Going across the rutted street cost me the transmission.  One of the tires left the ground for a second. When it came down BANG went the planetary assembly.  I limped the car home knowing there probably wasn’t much hope for the transmission at that point.  I decided then to use the transmission that arrived with the BPT engine.

The story does continue from here and you can read all about it in Part 2.
