Hey whats up, I just got my new 73 240z last night. It's pretty stock when it comes to about everything but suspension. So what i plan on doing is upgrading the engine for a quicker car. What sort of carb upgrades can I do to get better performance, I have K &N filters already, but do you think i could get duel webers or something that might be better than 73 carbs which I know aren't as good as the earilier ones. Also 4 speed isn't quite as cool as a nice 5 speed so what should I do and how much money am I looking at for a 5 speed conversion and will it work on the l24. I don't really want to swap engines yet because I want to take it easy because I am a high school student and my budget isn't too high so I don't want something that will guzzle gas alot but I could deal with a carb upgrade or something just not the .4 liters extra for now. Also it's too complex, i haven't had too many hands on experiences with cars so i am not very knowledgable, I know how it works just not what everyint looks like. I got a haynes manual. Are there any other books to get too? Sorry, I babble good don't I?

Well, I just got my new '73 240z today as well. It's pretty sweet. Anyway, if you can afford it, go with a triple weber setup. If you do a triple weber setup right, they can work really well with a stock L24. Also, if you want a little extra kick off the line for not too expensive, get a nice 3.9 or 4.11 rear differential. I am no expert by any stretch but there's my 2 cents. Also, I am sure that you are familiar with parts sources for z's but if you aren't, www.zcarparts.com and www.victoriabritish.com are good places to get ideas for mods.

hey thanks for the reply, somewhere I heard that a triple weber is too much for the l24 and it cant really take advantage of the full triple web potential.
