JB weld can work miracles. It might work if you use something between the two pieces and epoxy that in as well.. Kinda like a split for a broken arm.. when I busted mine. I almost had to buy a whole car with a bad motor to get one.. lol.

I was able to install a normal Mazda6 rad support on my Speed6 after I had a dumb mishap with my floor jack.

I've got a spread sheet I use for building MAF cals from logs.. When it comes to data logging get your self Megalogviewer HD.. You can get the Non HD version for free, but trust me. Pay for the full version, it's super cheap. If you want I've been working on a series talking about tuning in...

Looks like you are using one of the Versatuner base maps as your starting point.. Looking at your tune, you haven't done much yet.. Even though your AFR's look good, your MAF calibration is choppy. I've seen worse and this might not cause issues, but it's not correct either.. It needs to be...

UV Die can be miss leading. Engine oil will glow with out the die in it. Even though it wont be as bright. Coolant will glow brightly. Old leaks that were fixed but not well cleaned up can show up and send you down rabbit holes.. The key to finding leaks is to clean everything very very well..

If we want to understand how various maps work and when they are in effect, we need a starting place. For now we are going to assume everything is working normally, targets are being hit without any issues, there's zero knock present. Let's start with the APP tables. It's important to know that...

Waste gate duty cycle is the key to understanding what you experience.. When you have all the boost, your duty cycle is 0... This is because something is sticking.. Either the Wastegate it's self stuck closed or the boost control solenoid got stuck.. The duty cycle goes to 0 because the...

No it wont.. We aren't talking about some kind of massive leak.. If your turbo was leaking, you'd likely be loosing more oil then that... 1/2 a quart in 3 - 4000 miles is pretty good for a used motor. Brand new cars can burn that much oil and the manufacture would consider it "normal"

It's the line going from the valve cover to the intake before the turbo. It's part of the PCV system. even if this isn't your problem it's go to do this kind of health check before going down the rabbit hole of an upgraded turbo. When you've got 2 cylinder that show good compression but have...

Before condemning the turbo make sure you don't have any leaks above it. Also pull the intake off and look for oil inside possibly coming from the Valve cover vent. After that do a leak down test on the motor. Not just a compression check. My speed 6 had a leak like that, the motor had blow by...

Remember a previous post I made where I showed you how it was possible to calculate the theoretical crank HP? I started with the stock WOT air load command, Sent it through some basic calculations, dove into the stock VE map a little bit.. and spit out this image? If you don't go back 1...

FORScan with a subscription should allow you to do a factory reflash yourself.. It's been a long time since I've done it so I can't guide you on the process. This will erase what ever tune might be on it and let you start from scratch..

With those updates out of the way, how about we get back to the Speed 6 and some of the tuning stuff I've been playing around with. Anyone interested in a MAF tuning excel sheet? After doing a bunch of MAF tuning on Fords and GM's I built this sheet to mimic what you can do in the HPtuners...

It's one of those things. Do you dial it back to help save the motor or keep pushing and accept the shortened life span.

Hows Eric Kutil keeping his motor together. compared to what your program is?

While the Protege project was under way, "Princess" came out to play. This is my autocross/track focused Mazda 323. It was originally built by my friend who passed away in 2018. Yep, the same friend who owned the Protege. Him and I spent a number of years building our cars and racing together...

This is a common trend with tuning. If you're tuner isn't telling you there's a problem.. Keep following what they are asking you to do. Some times is takes a few revisions to get things into a decent place. Unless your tuner is telling there is something wrong that needs to be diagnosed, sit...

It's that time of year again where the summer fun has come and gone. I've got time to brows the forums, sit back relax a bit and prep for next years adventures. I haven't spent much time with my Speed 6 in the last 6 - 7 months. My son was hit while driving his Mx3 we rebuilt. No one was hurt...

They don't make a coilover for a 323/ Mazda BG platform. I am at that point I need to have someone go over my setup and better spec out a setup. The Ksports I have aren't offered anymore and whats out there is bottom the barrel cheap for the general enthusiast... It's time I start saving for...

It was, but worth it. Looks OEM.
