Thx joe_z for explaining. There was also a write-up by Shawn Fogg...

He got about .75 psi extra boost from this mod.

BTW, I have been slacking and not checking the forum. If you are interested my email is kai23@netzero.net

It is still available since it wasn't needed for TC535i's install. A note to those that are interested: Only 1/94+ M42 and M44 engines have the ventilated injectors and can benefit from this mod.

I'll buy it. I sent you an email via the boards email link. Let me know how you want the payment. I do have paypal and it's a verified account.

Just to make sure, I have a dasc'ed '96 1.9L Z3. I don't see why it wouldn't work.

My email I check daily is brancarps@gmail.com

Thanks, Bran
