I was after some advice relateing to keeping the engine of my 75' 260z strong and reliable. Im new to engines and was just wondering about some simple and small cost ways to increase power and strength in my engine. Im only new to engines as i said so please be gentle.

If you're brand new to engines, just pay someone to tune it. New plugs, timing, maybe plug wires, etc. Keep all the lubricants and filters up to snuff. If you really want to get into the mechanics and aren't in a hurry, buy some repair manuals and maybe find someone close by that is knowledgable and can show you how to do some things. Lots of things to do to the engine to increase the horsepower, but it costs. Good luck. Victor.
