The 65mm TB assy swap was tried but it couldn't work right..... The voltage coming from the Datsun ECU is way different than that put out by the Ford....due to different parameters the different systems have.... the air requirements were also way different.... The only way it can work right is if you perform a 5.0 or 5.8 liter ford engine swap along with the MAF setup. I would definitely look at the 64mm TB swap as your L series engine can only take advantage of the added airflow at higher rpms anyway.... This TB swap provides much more air than the L series N/A motor would ever use (street engine wise)

McGuinn, Depending on hw the car will be used, I would opt for a mandrel bent 2.25 inch exhaust with a 12-14 inch glasspack resonator approx 10-12 inches from the header collector (provided its a 6 into 1 header) and your choice of muffler in the rear....just remember to stick with the same config your Z uses....inlet is center and exit is offset etc... FLowmaster units you need to use a 2 chamber which is raspy on idle and really gives the L series 6 cyl engine that ferrari like whine....the small pipe also gives you INSTANT throttle response and low end grunt. If all out performance is what you want, get the mandrel bent 2.5 inch (you will need a longer resonator to mitigate midrange resonance) and also stick with same config muffler with brand of your choice. Just keep in mind, the more you uncork the engine, the better the top end performance, the LOUDER it will get. I would get an exh system made by a competent shop.....that MSA stuff is of marginal quality in my opinion. just my two cents. Roberto
