RB Fairlady

We can get NT555R's in the us, but I'd suggest some M/T Drag Radials instead

Rod length plays a very, very large part as well. 4500 feet-per-min is a safe limit for stock rods (6000 fpm for nice ones) RB25 rods = 71.7mm Piston speed = (Stroke * RPM)/152 =(71.7*9000)/152 =4245fpm A stock RB25 bottom end is limited to a little more than 9000RPMs If we shoot for the 6000 FPM number... =(71.7*12750)/152 =6014fpm A fully done up bottom end should safely withstand 12750RPMs routenly. That is just the lower end - valvetrain and fuel mods would be necessary too.

Something popular in the states is to get the fans off a Ford Tarus from a wrecker. I believe they were sold as Falcons or Fairlanes... FWD family car sold sence ~88 to present... They are really plentyful in wreckers here, and the fans are big and efficent.

A post-TB AFM would not work. When the TB is closed, there would be no air flow. And #2, the AFM isn't calibrated to work in that location - Most AFMs are supposed to be before the turbo i.e. non-pressurized. The major stalling problem is when your dealiting with venting BOVs. THe ECU sees air going into the turbo/intake track, but when the BOV vents to the atsmosphere, the ECU looses track of the air, so at the subsequent idle, the ECU thinks there is way more air, runs pig rich and drowns itself. A remedey of that is going to a different AFM type, or getting a computer to mount the hot-wire afm in a new place. Most aftermarket computers replace the stock AFM with a MAP (manifold absolute pressure) device that doesn't read any airflow in the track, but regulates fuel by intake pressures.
