🔧 BUILD K swap miata

[AnimalMother316]

If you're pushing it around the road course I would probably look into replacing an original radiator. Deposits Etc do buildup on the inside of the tubes and in between the air fins and reduce Cooling....

Is this more to your taste?

It's fucking glorious.

Carb on an axial roots lol

Don't forget cantilever suspension

Okay, so this "oh the battery drained business" Is not what I thought.

Recently drove it to and from work. I live really close and it barely made it home. Gauge cluster turning off and Seatbelt light flashing.

I was driving on battery charge.

Checked fuses, grounds, and wires to alternator look good.

Car off power and ground at the alt read 12ish
battery voltage. Running it jumps down to 9.

The voltage regulator is inside the alternator. So, everyone says I'm better off just buying a new alternator. Instead of rebuilding.

 

[AnimalMother316]

Good ol K series.

Every major auto parts store had an alternator in stock.

Throwing this new one in tonight.

 

[AnimalMother316]

All done.





Glad it was alternator. I fucking hate hunting down electric shit.

Having the Bluetooth ECU is so nice too.

That alternator looks like it's seen some miles.

Yeah, I can't quite remember if I bought it used or rebuilt, cause obviously the pulley is newer than the rest of that alternator. Lol

So, this stuttering problem I've been chasing the whole time... I thought it was the tune. I thought it was the tps. I shortened the throttle cable. I put on a heavier spring for the blade.

All these bandaids. It's an issue with the casting of the throttle body. I talked to kit company and I'm being sent a new throttle body free of charge.

Hoping to put that on Saturday to enjoy the weather Sunday.

On the docket:
Get 200tw tires
Add new resonator
Move axleback flanges to make room for diff brace
Enjoy autocross

 

[Mr_Roboto]

The throttle body? Aftermarket?

The glory of jelly bean parts.

Yeah 3in b series throttle body.

Idk how much of it is like proprietary. But the wheel to match Miata pedal travel better. And k series has iac and dwb

 

[AnimalMother316]

Hard top off, summer tires back on. Gonna be ordering new tires soon, the rears are getting close to toasted.

Edit: Soon is very soon. 4 rt660s for $630 love these small tire sizes.

Threw on the new throttle body. Gonna mess with the tune tomorrow. I wanted to let some loctited bolts set.

Rearranged some vacuum lines. Changed up a crankcase vent. Need to get a small filter for that.

Talked with my welder hoping to get that resonator and diff brace thrown on next weekend.

 

[AnimalMother316]

Drove with the top down.

Fucked with idle a bit but no luck. Car drives fine otherwise. It actually idles as it's supposed, but if you tap the throttle it jumps to 1500 or 2000 and just sits there.

Idk if I haven't given the ECU and iacv time to relearn after flashing.

My friend is convinced it is the throttle body again.

But the throttle spring may be the issue. The belief is that at low throttle the spring doesn't have enough tension to bring it home to proper idle. If you stab it the throttle comes back down to where it should be.

 

[AnimalMother316]

No clue what I fucked or unfucked but the new throttle body is on and good.

But also I definitely need these on sooner than later. I was skating around on the wet ground earlier.

... Not that these would be better lol.

 

[AnimalMother316]

Got the diff brace in and the extra resonator.



Definitely less rasp in normal driving.

Tires should be on soon.

 

[AnimalMother316]

Did trans and diff fluid on the subie yesterday.



Oil in the Miata and new tires mounted.



First event is 5/7 but I've been getting slaughtered at work so giving up my only day off is questionable.

RT660 very very sticky, you will have much grip.

 

[AnimalMother316]

Definitely sticky.

I'm rubbing somewhere though. Hoping it's just the pass side fender liner. Driver one is gone already.

Gonna check wheel clearance with the wheel turned.

 

[AnimalMother316]

Hoping this is the culprit. Front passenger fender liner. Looks like I can pop in some retainers or ziptie it down.

The rubbing did sound like when my mudflaps were dragging on the ground. So hoping it was just this plastic.

 

[AnimalMother316]

Confirmed sticky. Was driving with the top down pelted my arm with pebbles and a bunch made it into the car.

 

[10sec]

Most people don't know the sounds of rocks being thrown all around the fender wells and into the car. Wait until after a rain when all of the road debris that NOBODY knows about gets thrown back onto the road where the tires follow.

And you might be rubbing because these tires are massively oversized, I would argue a 255 (what I have) is a 275 and if not definitely a 265. Both my friend and I noticed how much wider they were immediately, his where rubbing on his fender when his old 255 RE-71's weren't even close.

I fucked with a few more things and as far as I can tell no more rubbing. Drove like 20 minutes with no radio. Taking fast turns slow turns. Slaloming back and forth for weight transfer.

Seems good now.


Although I let a friend drive the car and he was cooking the clutch. I had to be like dude are you on the clutch? I've had like 5 other people drive it with zero issue. I should've been more selective lol.

Clutch isn't fuckered so it's whatever.

 

[AnimalMother316]

Okay well the mudflap was definitely causing some of the rubbing.

It almost got ripped off when I made a turn to work this morning.



I still hit the fender with the old baseball bat roll.

The perks of a beat up body.
