Has anyone ever fly cut their pistons? Is it done just to lower compression? Or does it have some kind of HP benifit? I would love to get an answer on this one guys. Thanks Matt-

Summer is coming in las vegas where the temperature will go up to 115. I have no over heating problem but I want to have the engine to run cooler because I have A/C all the time. I installed this winter an original fan shroud which is supposed to help running cooler in traffic at idle. Is someone has other tips I can try to improve better idling in hot climate? Also, is someone has ever experienced isolating the gas lines to solve percolating problems? When it is very hot and after many stops and start again, the engine is harder to start and idle roughtly for some minutes. I suspect the gas is evaporating to fast in the carbs and and it idles better after when some coo…

With the price of gasoline creeping upwards and my new 1973 240Z slowly coming apart for a complete refreshing/updating, I had the wild thought last night of converting my fuel and induction system to run on E85, that is, motor fuel formulated with 85% ethanol. I'd rather not debate the pros and cons of ethanol here. I know that there are a lot of opinions out there, but the fact remains that we have a pretty high number of stations here in the upper Midwest that sell this fuel, and their numbers are increasing every day. Plus it is cheap - anywhere from $.50 to $.80 cheaper than regular unleaded. Have any of you guys ever heard of doing this? It seems that an old, car…

I searched the galleries and couldnt find any pics of the 432 exhaust plumbing (based on keywords people put in). Could someone post a pic of the underbody with a good view of how the twin pipes are arranged? Thanks in advance

since I rewired my Z it is running really poorly. It misfires very badly when cold and is only slightly better when warm. The power band totally goes flat at about 3000RPM. Timing is @ 7degrees. My mechanic friend and I were moving the timing around yesterday and it only improved slightly...I have the Pertronix ignition. I know the carbs aren't tuned to perfection, but I don't think it should run as poorly just because the carbs aren't just right. My friend recommended I should start by getting some new spark plugs and then we can start narrowing it down and get it running smoother. Any suggestions for where we should start looking for the problem? :classic:

When installing a new oil pan gasket, what's the recomendation for using an adhesive, such as the Permatex products? In the past I've had good luck on other vehicles just cleaning the surfaces and installing the gaskets by themselves. Right now I've got the engine out on a stand so I want to do it right while it's still easy:classic:

I'm trying to get the facts here... Did Nissan make a set of competition headers for the 240Z? Is "Nismo" the factory performance arm? Are such headers available in Australia?

Title is misleading. I already know where to put the sender for the oil temperature gauge (in the port for it in the oil pan). What I need to know is where to put the sender for the oil temperature warning light. Longacre says only, "Install where oil flows into engine." Is there anywhere to put it in an F54? steve
