I finnaly dug my z out from under some snow and rolled it into the shop for the beging of an expensive journey. I am starting on the engine and have ordered " How to midify your Datsun". Does anyone know if this is a good polace to start? Also what is a good running Mild cam and what modification should I plan on for the head? Also this is a 73 so people have told me to junk the carbs because of problems with vapor lock. Any ideas there?

What head should I use on a L24. I hear the E31 is the best and I might be able to get one. It has a E88 on it now. Any advice

Well I have a '73 240z and right now im refinishing the L24 engine. It has a four barrel Holley Carb. set up and I was wondering if I still needed the Flow Guide Valve? The person who set it up a long time ago left it in place and it looks weird not being hooked up to anything but the Vapor vent line which goes to the Vapor Liquid separator, above the gas tank. Thanks for any help.

Hi i have a question abou the L24 engines. how much hp does the L24 engine from the 240Z produce? was it ever fuel injected? I saw specifications from a chilton manual stating that the 77 and 78 810 with the L24 could produce 154 hp and it has EFI. but the 79 810 with L24 only has 120 hp. anybody know why? and anyway to modify to the higher hp?

Hi all, Great site. After some time drooling on Z Car forums I have finally become a "Real" member of this community as I have recently purchased a 240Z. My baby has a late 280ZX with FI. I was wondering on any easy, cheap mods that can be done to increase HP. Any information will be most grateful as i am still a novice. Look forward to hearing your ideas and thanks in advance for your time in replying.

Hi there, this goes out to anyone who can help me, I have fitted triple Webers to my L28 engine which has been modified and am looking for any suggestions on jet settings for the carbs, i think they have been setup for a 260z standard engine at present so they will be wrong, and the engine seems to over fuel on tickover. Any advice would be well appreciated
