In light on Andrew's new purchase (sweeet car!!!) I wanted to gloat a little about my recent pickups that I thought were a great deal and ask a question as well.
1. Jet hot coated msds headers to replace my old unknown coated msds headers only $299 plus shipping!

2. Brand new K-jet air flow meter only $45 plus ship. I thought this one was a steal. 928 intl lists this at $200 used, and since I already did my head/cam gaskets and misc hoses, I am going to replace and clean the stuff I didn't get to in the intake.

Now for the question, my old msds headers had the hole for the o2 sensor welded shut, but the new ones look to have an o2 senser there. I want to add an air fuel ratio guage, something like the arm1 from 928 spec. Since my k-jet does not use an o2 sensor can I have an o2 sensor run it directly to an air/fuel guage? Can I use any guage or is the arm1 caliberated somehow for our cars?

 

I think you can use any guage. You will have to tune your car to find where is produces the optimum power. Most 928'ers using the ARM1 find best power on the last green light/first blue light. THis may be different if you were running a vett or even a different porsche. Heck, it may be different between from a OB to a GT. I look forward to finding out!

 

the arm-1 won't be real accurate as a tuning tool. if you're planning on mods that may require a lot of tuning and you don't want to spend alot of dyno time you should check into the lm-1
