The third one earlier is finished from the back. The front is nothing special. Plenty of people have swapped headlights. Miata.net is full of 'em.

Oh, and do your homework. Apparently there is something different about the MSM headlights versus the "normal" 2001+ lights.

PS: yes, the hood is VERY dusty. Been sitting a long time...

But I'm scared of Miata.net.
More homework to be done. Thanks for posting the pics though. Looks pretty good.

It already is. In fact, I just got back from another drive in it.

Going to COTA with it tomorrow.

I posted the wiring diagram and mods for the headlight swap in my build thread. I made brackets to hold the bumper cover closer to the headlight housing. The wiring diagram will also allow to use all four bulbs when using the high beams.

Back to work on this.

Wired up the IAT sensor in proper position last week, so I can now answer this question. Basically, I get IAT's just a few degrees above ambient if the vehicle is moving. If it sits in traffic for awhile, it can go up 10-15 degrees as the intake heat soaks, but it goes right back down again once in motion and fresh air bathes the sensor.

Some hood venting will fix the soak problem...

Andy,

Where did you move the IAT? and where was it originally?
I'm currently planning on using stock s2000 IAT and same location, do you think I should move the IAT to the Intake piping?

Here is my current location of the sensor.

Leave it there.

In theory, IAT in the manifold is actually closer to what the engine sees anyway.

Mine had been hanging in the engine bay near that cowl opening because the harness did not have enough wire in it to get to the intake piping. Now its where it belongs in the actual intake stream. I suppose I could have drilled another hole in the manifold and installed it there next to the MAP sensor, but that would have required removing the manifold.

In other news, the Miata is now as quick on track as my CRX. That was a huge milestone and confirms the platform change motivation. Still not as consistent, as I'm having trouble getting all the power down even in 3rd gear coming off corners. 225 Rival-S on 9's can't handle 300hp in 3rd unless you are perfectly straight. And I am going through rear tires at a prodigious rate as a result. On r-comps, the solution would be a no-brainer...but One Lap rules say 200tw.

So...time to do "what they say can't be done".

Any plans to test the 245 width Maxxis VR-1?

Unless the sensor can heatsoak, like the GM one*

*I know nothing about s2000 AIT sensors. For all I know heat soak may not be an issue

Yes.

But I don't expect that to be my final answer. Given what Emilio was saying publicly (VR-1 = AD08R performance), it would likely deliver performance on par with the smaller Rival-S but last longer. I want both faster and better wear. Still worth testing, though.

We are at an interesting time where the fastest 200tw street tires can deliver a couple fast laps similar to a streetable track day tire (e.g. NT01, R888, RA1, RC1), but then fall off. But they don't last anywhere near as long as those track day tires. They are essentially rules-beaters for autocross and time trials. Similar to the difference between Hoosier A7 and R7, though at a lower performance level.

The previous crop of 200tw tires delivered both long life and consistent performance for whole sessions. Perfect for crapcan racing and budget track days...not to mention dual-purpose daily use.

Size also plays a factor when dealing with the whole 23" tall tire deal. In the last GRM track test, we found that a 205 RE71R was faster than a 205 Rival-S, but a 225 Rival-S trumped all.

I smell another tire testing article...

I think the current 200tw group are the epitome of the perfect STREET tire. Long wear when they are cold/warm, wacky grip when they are hot. Far improved from the last group for true street cars.

I also saw none of the drop-off you talk about in the Rival S, even over long enduro stints (2hr).
