I have an opportunity to purchase a T5 transmission from a 90s mustang very cheap. I was wondering if it will fab into a 72 240z with the stock L24? I'm looking at sometime in the future going to a small block V8 but not soon. I'm wondering about what bell housing I need and will the shifter be located correctly?

Hey mates This past evening I changed the plugs out in my Z as she was running oddly rich and rough. This is what I found. Can someone elaborate on why my plugs are orange? They are a bit cooler (5 on the heat range) but I'm wondering. Thanks Jan

Mates I know this has been discussed before but I can't for the life of me find the thread it was on. Is there anything wrong with running BPR6ES in Zs? Thanks Jan

Hi Folks, Quick question for ya all... I started working on my 71 z the other day.... It's been about 5 years or so since I last drove it, When I put it under the car cover the Z was drivable, but when I went and started it up the other day and pressed on the clutch... the peddle went straight to the floor board with very little pressure needed... I checked under the car, and I saw no signs of any fluid leaks.. I checked the clutch cylinder and it was full, I'm planning on bleeding, and replacing the old clutch fluid tomorrow with new.... but I was wondering if anyone knew is it possible for either the clutch main, or slave cylinder seals to leak from sitting so long and …

Guys Ever since I bought my Z in 2009, it seems that everytime I do an oil change the car will be noisy for the first week or so afterwards. By noisy I mean I can hear the chain rattle at idle and when I let off the throttle. I originally thought it was the chain and replaced it - about two years ago - but it didn't really change anything. I'm going to take the front cover off in the future to replace it, but I wondering if anyone has any ideas of what this could be and why it does it after oil changed. Thanks Jan

Well it's been one of those days. Played around with my carbs and went for a spin. I noticed my engine has been pinging more lately and I needed to check my timing, so I turn around back home and get hard on the gas-everything good! I get home and smell coolant and it is running down the drivers side of the block front to rear. It's coming out good, but the car is running fine. I shut it down and look for leaks. It is about impossible to see under the thermostat housing, which is my first suspect. Then thinking about all that pinging---WHAT IF its my HG:cry: I can't find where it's coming from, so I start it back up. No leak, car idles perfect. So I wait for the thermost…

Guys This weekend was supposed to be wonderful. A group of friends and myself were going to meet up at a lake and have a wonderful camping trip. Well as expected there were issues from the start. On the way to said lake I forgot some things at home and decided to head back. As I drive into my neighborhood I notice my temp gauge is not where its normally supposed to be, to be exact its a notch or so past the midway point, it normally runs at like 1/3. Freakout I pull into the spot and open the pressure relief on the radiator cap - yes I know you're not supposed to do it I wasn't in the right state of mind - steam comes pouring out for a good five minutes. Stumped I attach…

Well I have been doing a lot of work on my 71 240 and getting ready to finally put her back together, but really want to have the trans gone through. I have gone through the engine (complete rebuild) rebuilt the carbs (SU type), replaced all bushings on suspension, had complete body re worked and painted, new window seals, and windshield. It's been a long two years, and now I need to go through the stock 4 speed, but am a little hesatent to tackle the job myself. I have worked as a mechanic for several years in the past, and have worked on many different types of automotive and marine engines as well as marine lower units I would like to do the job myself, but I've never …

I have what could be described as a white noise coming from the rear end of my 72 240. soon as the car starts to roll anything over 5km/hr, it sounds like someone has left an old analogue radio on a hissy channel of static under the rear diff area. the noise is not loud and could easily be ignored with music or aggressive driving, but just slow cruising makes me wonder if there's a problem brewing under there. at first i thought it would be just the brake shoes slightly rubbing on the drums, but the sound doesnt change with brake pressure. I'm thinking i have a bearing in the rear end thats starting to get noisy. diff fluid is relatively new. any thoughts would be appreci…

My harmonic damper decided to come apart on my track car last night. It was only 54 weeks old (52 week warranty). It used to look like this... "The manufacturer reported safe rev limit with this Damper is 10000 rpms" I'm hoping the engine was not damaged. Time will tell. Any recommendations for a new damper? I'm leaning towards this one... http://www.bhjdynamics.com/index.php?main_page=product_info&cPath=10&products_id=241&zenid=0usn3hloiia3ff5sr1himig8n6
