Hi Todd,

I own a Callaway turbo 535i that had been discussed in the old thread below. I reopened the old thread when I should have just started a new thread, sorry. The old thread is below.

I have a few questions for you regarding the Callaway kit in this car. Could you answer the following questions please:

1. It has an extra cold start injector in the pipe running to the intake. This CSI is connected to a small electrical box under the dash. I assume this is to fire the CSI to provide extra fuel under boost, correct? Was this what Callaway called a "Micro Fueler"?

2. What type of turbocharger will the Callaway turbo manifold accept?

3. Is this system worth updating? I am thinking of either putting it into my M30 powered euro e21 or into my e34 535i.

Thanks for your time.

Tony

Throw out the Microfueler. Manifold is fine if the flex portion isn't cracked. Uses a T4 turbo with on center housing.
