Anyone out there running a bored out throttle body with F/I? I have some extra cash and am looking at increasing the air flow in the motor. I have the Vortech and a bunch of otheer ****. I am kinda eyeing the Crawford one which is a 73mm one and it costs about $250 + core. Please chime in if anyone is running one of these.

I am also looking to get the L-SPEC reflash and a retune. If I get the flash, would it be OK to drive the car as long as I do not get into the 6600-7200 RPM range? I ask because I want to send off the ECU to get reflashed and then drive to CP Racing for the retune which is about 360 miles from my house. Any help on these matter would be greatly appreciated.

 

$230 is not worth it to me for a 2-3mm bore-that is all they bore. Also, with my recent TB failure I have heard that earlier Z's are experiencing this, so to me its not worth it to pay the $$$$ for minimal gains then have the TB fail...

 

Do you know what the OEM bore is? This one is a 73mm one. I wonder if that little bit would make a difference when air is being forced into the motor!

 

Well I called Jim @ Proflow he told me he only bores 2-3m, to me thats not worth it. Ive had TB's bored local to max safely for $100 so if anything Id do that before I payed $200+
