does anybody have (or know of a place i can get) cross sections of an l-series head? i'm wondering for porting purposes.. i've seen an illustration before, but i can't remember where i saw it. p.s. when people say that pulling the exhaust liners out of late-model heads is a PITA, they aren't kidding!

I am trying to locate a set of 6 L20a or L14 rods. Yes, I have searched this forum as well as the internet. Does anyone have the Part #'s? In what engine/car were these rods availble? Are they available in the US? Can I order them from Nissan or get new OEM's anywhere?

I found this website in my new Turbo Mag. http://www.9secondracing.com/partnum/2654/parttype/19/partcat/20/HKS-Nissan-280ZX-Turbo-1981-83-(L28-Engine)-Adjustable-Cam-Gear.html They say that HKS has an adjustable cam gear for the 280ZX and Turbo. I e-mailed them the other day and have not gotten a response back. I just wanted to bring it to the forums attention to see if it is truely possable or are they pulling our/ my leg. Thanks

Guess what I found today?............ I discovered the head gasket was leaking, I warmed it up pop the valve cover to re torque the head and it is maxed out, my guess it was over torque and the bolts are maxed out as well….. History, for those of you that do not know I bought this 70/240 after it was sitting for some 6 -7 years and am bringing it back to life….the OD says 130K miles the previous owner said the head was done 30k back. What do you guys think should do, pull the motor or just redo the head again? What would your next step be??

I finally decided on what I'm going to do with my 240.. It's been sitting in the garage while I've been debating on weather to keep the car, and get it painted or put it back together and sell it as is.... I'm going to keep the car, and get the paint job.. Now a question about the heater, and radiator core, and related hoses. The car has been sitting for about 3 to 4 years, while I've been replacing this and that on the car. I have tried to be good about starting it up once every 3 to 6 months and let it idle up to temp, just to charge the battery, and circulate the coolant, and oil. I know coolant, and oil brake down due to age, and should be replaced every so often, a…

Hi, I just bought a 72 240z, second owner 112,000 miles. No dash cracks! This car is in great shape, all original. I would like to increase performance. Where should I start? Where is the best place to purchase parts? Any feedback is greatly appreciated. Thanks, Gordon

I recently purchased the engine below on eBay. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1,1&item=4539470286&sspagename=STRK%3AMEWA%3AIT It comes with the P90A head which I have never looked into because of the work involved to use it on high compression n/a applications. My understanding is that these used 'hydraulic lifters'. After looking at a few pictures of them, I don't see any noticable differences in the valvetrain. Could someone post some pictures of the P90A in detail? I just dont understand where the lifters come into play. Thanks

Hi guys, So i swapped my old points distrubtor today for an electronic 280z one (I am very impressed) and i thought it might aleviate this problem i'm having with an intermittent popping sound when the car is idling, but it's still there. The car idles at 550 rpm beautifully, then every once in a while you get this popping sound (like a hickup) somewhere within the intake, then it goes back to normal idle, until it happens again ~30 sec later. This repeats all the time while the car is idling. It in no way affects preformance, on the gas, (The car pulls extremely cleanly and quickly to 6K, with the new electronic dist i might add) Any ideas?
