Saw one on a Z. Can't seem to find Zgarage tonight, but don't remember ever reading about an e-30 head. Am I having a brain-fart? steve77/86

again, the car is a '73 with roundtops. i was on MSA snooping around and what i'm thinking of is the stage 2 or stage 3 cam kit and the 3-2 coated headers. i will be doing a little port work on the head myself and have it milled to increase CR too. when i have it milled, do i have to shim the cam towers? i noticed they listed a separate header for the '73 from the '70-72. why? will the SU's support this if they are rejetted? (sorry, i don't really know what is going on with them. more of a quadrajet kind of guy). pertronix with a hot coil and new pipe with something like a flowmaster will likely round out the engine mods. any other suggestions? BTW, this will not …

I have a '71 240Z that I've recently aquired. I'm new to these cars and are full of goofy questions: 1) The air pump belt is missing. If the air pump is not running will that effect how the car runs? 2) What octane rating should the gas be? 3) What brand of motor oil and filter should I use or does it matter? 4) In my repair manual it shows a flow meter for setting the carbs. Who sells flow meters? In general, what are some good parts companies, catalogs, web sites, ...? Thanks

Ha guys, Help me out here, please. I have fallen victim to the need for more horse power...imagine that! I live in California and want your opinions on who I should go to to have an engine built. I want a naturally aspirated engine and have been told that I can get a streetable 250HP engine, using triple webers on pump gas. What do you all recommend?

I have been searching and searching for the best choice for my L28e..... with N42 head, for performance. My first modification, I plan on getting exhuast. However, ontop of the exhaust, I naturally have a choice for headers. According to my research based off of this Forum, Zcar.com and HybridZ, a new set of headers is completly useless.. *UNLESS* you get equal length headers. This will allow the flow to be improved, but based off of people who have purchased headers, they rarely feel a big difference, other than the sexy sound. Also I have read that new headers, will increase your Temperature under tha hood.... compared to the stock manifold What I am trying to ask,…

I bought a cam from motorsport (part# 10-2003) and I put about 6000 miles on it. after pulling off the valve cover to inspect it was very worn. I think it wasn't geting enough oil. Do I need to block off the cam oiler with the block off plates or do I need a new cam oiler? thanks

I just acquired a 1971 240z sportser. I noticed that the exhaust pipe under the car has rusted away leaving a 1 foot gap in the middle of the pipe. I wanted a good system but didn’t know what to buy. I would appreciate if someone could give me a recommendation. Thanks again, Mc
