Hello all I'm a first time poster here. Picked up my 1976 280z auto last week and began picking up turbo parts. I plan on running a holset hx35. Now I've gathered: P90 head, which is missing a rocker arm. This will get machined and ported/polished. Megasquirt 1 extra. Not sure what sensors I need to pick up that my l28 doesn't already have on it. Also picked up an intercooler and piping. Now I know I need a tps off of a 240sx but have yet to find one. Is there any other options? To complete the list I believe all I'll need is: BOV, wastegate, turbo manifold, supra injectors (what year?), and I'll do the downpipe and 02 sensor bung myself

Hi all, My 240 engine needs work, I found a low mileage 79, 280 engine with N-47 head and tranny. What am I looking at to do this transplant? I'll be using S.U.'s I want to be clear on what I may need for parts or change's I need to do. Thanks, John

so after replacing the head and futzing endlessly with the timing chain, i finally got her running. went in to do a valve lash adjust after ~600 miles on the new cam and discovered my cam chain was quite slack. while rotating the cam by the bosses i felt it turn a few degrees as the slack picked up in each direction. when i replaced the head, the chain was super tight - so much so that i had to lever the cam sprocket on with a big wrench. it seemed too tight to me, but everything i read stated "zero slack" and that's what it was. the first startup turned over verrrry slowly for a few revolutions, then something clicked and the engine spun free and started. i figured the …

I have an R200 LSD Diff and a 82/83 5-speed tranny, and I'm going to be swapping out the gear oil in both with Royal Purple before I pack the car up for winter. But, I must be going blind as I can't find the gear oil capacity for the tranny in the FSM or in a forum. I know the diff is 1.5 or 1.6 quarts, but how much does the tranny need? I'll be ordering it on Amazon and I don't want to run short. Thank you in advance!

I have scanned through the various Mallory threads but didn't find exactly what I was looking for so bear with me if I am covering old ground here. I just purchased a Mallory distributor with a mechanical advance for my 1973 240 running triple Webers. I currently have a stock dizzy, stock coil, ballast resistor, etc. Leading to the distributor, I have three wires - yellow going to the water temp sensor, a black wire and a green wire both attached to the dizzy. The green wire seems to just attach to the outside of the unit (ground?). Can I just run the black and green wire into the new Mallory unit with no further changes (keep all the other components the same)? I co…

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
