Good question. What I found is FRA is indicated in the Torque app as the Long Term Fuel trim. e.g., FRA 1.06 will be indicated as +6%

The RKATs I think are indicated as Short term fuel trims but I'm not 100% since the numbers tend to go up and down quickly.

Remember my OBC stalk went limp and Groovzilla gave me a stalk with the switch? Turns out one of the bolts of the switch fell off and the other one was very loose. Replaced the bolt. Added some loctite and it's good to go.

The stock lights are in a pretty sad state. Yellowed and pitted.

Not bad huh?

Very nice. I also had good success with the Sylvania kit. I did use a little too much of the clear though and got a faint run line between "strokes". Yours look perfect.

These results are from the Sylvania kit? Or, did you have to buff them first and then apply the kit?

Ahsai

Thanks, guys. Yeah, I only used the kit and more 400 grit sandpaper which I already had. All hand wet sanded and polished about 1hr per light.

The kit comes with 400, 1000 and 2000 grits sandpapers, a surface activator, clarifying polish and uv coat. The plastic lens is very hard so I needed to use more 400 grit sandpaper than the kit supplied. The trick is to wet sand with 400 to remove the top yellowed dead layer. Figure at least half an hr for that per light. Followed by 1000 and 2000 for maybe 5min each. Then buff with the clarifying polish for a few minutes. Then the lens will still have a white haze but once you apply the uv coat, they ill become crystal clear. You can see my drivers side light still has some yellow tint on it picked up by the camera. In person both lights have no such tint.

Just as a reference point, for the 23,386 miles I drove it as a daily driver (inc. 1 DE school and one road trip), I averaged 24.2 MPG. The road trip {San Diego to Ohio and back (via North Dakota)} was 5,469 miles, averaging 69.2 MPH and 26.9 MPG.
Also, the computer indicated MPG reads about 0.48 MPG higher than the actual numbers (my current 997 reads 1.7 MPG high)

Yeah, I saw your post and pics before and thought it was pretty amazing. Do you recall what oil you used at the time?

As I said before your old engine was really healthy and efficient for a 100k engine. Looks like my rebuilt engine is also as good. Hope it gets even better mpg after fully broken in. With the new found torque, it's difficult to keep a light foot at times though

Mobile 1 initially, then switched to Total 5W40 (per suggestion of the guys at Black Forest)

Ahsai

Thanks...was just wondering if the actual viscosity played a role in the great mpg. Usually thinner oil will return better mpg.

I used the Sylvania headlight restoration kit, which gives decent results.




BEFORE. Right headlight. Note the pitting on the upper part.



AFTER. Right headlight.



BEFORE. Left headlight. Note the heavy pitting everywhere.



AFTER. Left headlight.

cringely

The pitting is understandable considering some of the road trips I took it on (see post 921 above)

Ahsai

Right. It's not a big deal anyway considering how easy it is to restore these headlights.

Thanks to Ahsai for a very educational thread

This has convinced me to switch to spin on filter, filter mag and magnetic drain plug on my X51 997.1 at my next oil change

OT: does anyone know of a similar thread for metzger (GT3 or turbo) engines?

Ahsai

The x51 997.1 is a very nice engine. I think it's wise to protect it as much as possible.

The mezger engines are bullet proof hence no rebuild threads

Backmarker

On the Metzger, that's what I figured, but thought I'd ask.

The X51 is a sweet motor, it's my daily driver and the best street car I've ever owned.
