Forgot to mention the used motor I bought off m.net has a damaged head. Seller is no longer responding, takes no responsibility, neat. Careful buying anything off this guy MX-5 Miata Forum

I only asked for $100 back....

Using my original head, swapping it all together, manifold/intake.

The 99 block I'm using has forged rods and ARP studs, so that's neat. Hopefully its not junk.

Got the motor in, fired the car up (jumped it), and smoke started pouring out from behind the passenger seat. The ms3x was putting on a smoke show.

Took it apart

https://www.miataturbo.net/attachmen...ine=1444049757


Ordered the two new capacitors and a new diode, and my buddy stopped by with his soldering gear to help me out. Parts replaced, and cleaned up. Before the ecu went back in, I swapped my 96 alternator back on the motor. I used the 99 alternator since it looked newer, guess there more current output with the 99, might be the reason for the pop in the ecu. Didn't want to risk it again, old alt it is.

My friend who's been helping me with the swap stopped by and helped me get the car running better. Timing was advanced a lot, probably due to the key way damage on the old motor. Anyways, out of the garage on its own power, hasn't moved in 2.5 months.

Went out for a quick drive, everything seems decent. Taking it easy for the head gasket to heat cycle a bit before I hit more boost. Curious if I'll feel any power difference now that the car has proper timing setup.

99-up alternator has no internal regulator. It makes unlimited volts until all your components are charcoal. The ECU regulates the alternator voltage on 99-up. The '97-down alternators are internally regulated.

Miatas make poor drift cars because of their low polar moment of inertia. It is one of the things that makes them great road racing cars. It is more difficult to hold a drift angle with a Miata than many other choices due to physics. You picked a hard road.

Much knowledge, so wow, stance.

Stants things

Ohtsu fp7000 (spiritual Falken 512) vs Yokohama S drive. Both 205/50/15 on a 10" wheel.

S drives fill out the fender better, happier with the way things look now out back.

Funny, I was thinking the same thing:party:

Monk 10-06-2015 06:19 PM

Serious question; do you ever have issues with the tire escaping the rim?
I am unaccustomed to such activities.

Itty 10-06-2015 06:29 PM

:hatecat: That tire/wheel size is incorrect. :hatecat:

After owning the car for almost 5 yrs, numerous trips to drift events, some 150 mi away one way, drifting at said events, driving back, and an 800 mile trip, no. I've never had any issues.

Ftfy. And thank you.

Monk 10-06-2015 09:49 PM

I am surprised by the this, thank you.
Onother serious question, if you don't mind.
What do you actually look for in tires for a drift event?
It seems like a tire with good grip like, let's say an rs3, would be counter productive.
Yet I still see "drifters" using good tires.
Also, is the point of stretching tires to reduce the contact patch?
I want to believe there is science behind this.

Good tires still grip when sliding. And are more controllable than shitty tires when sliding. Shitty drifters use shitty tires to make up for shitty horsepower

Can't speak for others but I mainly do it to stiffen up the sidewalls of the tires I use at the track, aesthetics, and getting the fitment I prefer on the Works. Back in the 50/60's guys would run stretched tires to imp[rove track times, but that's back when tire tech wasn't nearly as advanced, so it's not that unheard of. For me, a little stretch helps with the tires I run at events. I don't run low profile tires, typically a 50 series, and many times a cheap chinese all season. A little stretch helps to make a meh tire a bit more predictable for me.

Using good tires is probably a traction thing, improved front grip, power, and again predictability, as well as how the tire burns. Sometimes the cheaper tires chunk, or begin to delaminate. Usually not an issue for me since my car doesn't really make a ton of power, so I can stick to the cheaper stuff.

On a side note, people really get emotionally invested over a little tire stretch and low cars on this forum huh? Guess it's better to vent those frustrations than lose anymore sleep.

Speed is also a concern with drifting. Even though it's a "sport" based on looks and style points, corner entry is a metric, which would be increased with more overall grip.
