This is what my tuner recommended: For a stock manifold, between cyl2 and cyl4. There is a flat spot on the cast that is perfect. For a header, on cyl3 because its closest to the turbo.

how far from the motor??

thrdeye · 07-07-2006, 03:54 PM

3 or 4 inches

I was always put them at the number 3 cylinder. I read an article, and heard from a couple guys over the years that the design of the fuel rails in some instances will not allow as much fuel to the #3 cyl, causing leanout.

Yea there is that theory.. but it's been well discussed here on nasioc, especially when the WRX first came out.

Many, many threads on this topic. Read and make your own decisions, I suppose. Personally, I don't think you should tune the car to the raw edge that running lean becomes an issue.

Put mine towards the front.

My 3 or 4 inches is always smaller than what my girlfriend thinks 3 or 4 inches is...

A man's perspective of 3 or 4 inches or a woman's perspective?

Yea.. it's the best way because you don't want metal shavings in there getting sucked intot he turbo.
