Hey guys.
I am fairly confident I will be at or below $200 for the kit, might even be able to throw in the filter at that price... I'll know an exact price when I finish ahardbody's intake.

For the pipe diameter, its still undecided as to exactly what size will be used.... the main problem, as I have discovered, is the mass-air sensor sitting right next to the intake opening. Just as my VG30's throttle body injection in my Pathfinder, you have to supply air to the sensor in order to work right, and it has to be exactly proportional to the origonal flow rate calibration so it will inject the right mixture of fuel... you cant just shove a pipe over the throttle body opening and call it a day. That being said, I will most likely be forced to use a large enough diameter pipe to completely fit over the whole round part on the top of the TBI unit.... from there I will be able to decrease the diameter of the pipe for the rest of the intake system to help out with velocity (yes your right Mervic).

By the way, now that the issue of cylinder heads comes up... if your port designs are anything like the ones on my SOHC VG30I, I can do WONDERS for your cylinder head flow capacity. If anyone wanted to lend me a spare cylinder head, I'd be happy to inspect to see if I can do anything to help the head flow better. Assuming there is, I'd do a full port and polish job for cheap so that person could test it for everybody here on the board... if anyone has any real interest in it, let me know.
