Has anyone had any experience with Datsun Spirit in VA? They advertise some impressive motors and I'm curious if anyone has dealt with them on anything and what they thought of the experience and products.

I generally lurk around her getting answers from prior posts but after doing a quick search I didn't see any posts that id where to get a flywheel for a '77 coupe. I have spent the last 2 weeks trying to find a new flywheel on line and all I find is the 2+2. I have already mistakenly purchased a 2+2 flywheel only to discover there are 240mm (2+2) flywheels and 225mm (Coupe) flywheels. My clutch kit is for the later. I've checked all my usual places to buy and keep coming up with the SACHS NFS5301 that I already have. Anyone know where I can pick up a new 225mm flywheel for under $100? So far everything I've found has been over $250. Or do I just bite the bullet swi…

My next quest on my '72 240z was to eliminate the leaks out of the differential (rear end). So while the rear suspension was out, I dropped the entire differential, cross members, and drive shaft. The transmission must be drained before trying to pull out the drive-shaft! I'd also suggest using a floor jack under the differential as it weighs quite a bit. Next I removed all of the pieces from the differential, including the half-shafts so that I'd have a manageable piece to work on. I then began to work on the side seals, as that was new territory for me. After removing the half-shafts, its as simple as removing the the center bolt and pulling out the axle stu…

My 3.54 R180 differential had the usual whine between 45-50 that changed pitch from driving to coasting. The FSM says it was due to excessive wear between the ring and pinion. This is usually blamed on pinion bearing wear. My solution is somewhat different. The clearance between the ring and pinion can be affected by the fore/aft movement of the pinion shaft. Differential rebuilding calls for inserting shim washer to adjust this clearance. In actuality, the shim assortment is used to accommodate machining variation in the manufacturing process. Since the bearing tolerance is much tighter than possible machining castings, you can normally replace the bearings while re-usin…

I'm starting to feel rather helpless. Finding info on parts is difficult. Just got my engine issues figured out only to find more missing parts ... (I will never buy a partially restored car again)! Can someone tell me the size of the bolts used to mount the manual transmission to the body in an '77 coupe? There are two rather long bolts that hold a cross-member to the body that then bolts to the tranny/rubber mount and of course mine are missing. No clue where the original bolts went and I'm currently holding it in place with a jack. I've searched the usual places for part numbers etc and came up with 11322-N3000 used in the '78 zx but I'm not sure that's the same he…

I want to change the motor mount insulators on my 76. I don't have a hoist. Can I just put a block of wood and a jack under the oil pan to raise the engine? How high do I need to raise the engine and what do I need to disconnect (eg, exhaust pipe, Trany Inuslator Mount, A/C connections, radiator hoses, etc) ? The service manual doesn't seem very explicit on changing motor mount insulators. Gary

I had a leak on my Manifold Heater Hose, (Rear Intake Manifold to Rear Tube, on a 1972 240Z), and replaced it with a 1/2" generic line. It was quite a struggle getting things back together, the hard line that runds behind the engine neer the fire wall has a bracket that bolds on with the rearmost exhaust manifold stud. It looks like the braket that holds the hard tubing should be adjustable but I couldn't get it to move, its either welded to the tube or coroded so badly its stuck. The two hard tubes I'm connecting are offset by 1/4 of an inche, so the rubber tubehas a bit of a bend in it that's putting more strain on the tubing than I like. My question is; is that brake…

Hello all. I need help from you Datsun CSI folks trying to identify the 5spd transmission I bought for my ’72 240Z. Here’s the scoop It has one mounting ear on the tail shaft. Has the long shifter mount. Those being said, it would appear to be a close ratio 81-83 5 speed. This is where the mystery begins. This tranny has the filler plug on the driver side of it. So maybe it is from an 810/Maxima. Further, the spacer between the front half/bell housing side and the tail shaft is made of aluminum not steel. Also,it has both a neutral switch and a back-up switch. My buddy and I have done the test turning the input shaft 20 times and counting the revolutions of…

When changing the filter and gasket on my AT a while back, I found a piece of metal in the bottom of the pan where one would expect to find a magnet. But this one showed no magnetism to speak of. Unfortunately, the new gasket did not fix the leak so recently I took the pan down again to flatten the flange where someone had over torqued the bolts. Lo and behold there were now two almost identical pieces in the pan. Looking at exploded parts photos, I believe they are parts of a broken "Low and reverse return spring". Could explain the occasional whining and slippage I get in reverse with a cold engine. I even found a replacement part for a whopping $4.53. Question: Just…

It seems i need to change my head gasket, i removed the oilpan and there was some white substance with oil.. I've never changed head gasket, so all the hints are valuable to me. I really hate the idea that i need to dismantle half motor but guess i have to.

i have a '73 and i've replaced the clutch slave several times. it will drive good and strong for about an hour then the piston is forced all the way forward, sometimes nearly out perma-clutching (forcing the yoke forward, jammed) until i can get under there to unbolt it. even after removal from the line the piston wont go back into the unit. i now keep an extra slave with tools in the car just in case. good thing they are just $12 a pop. is there an adjustment i am missing to lessen the pressure?
