I am looking to buy a clutch LSD r160 from an old subaru any thoughts ? Is the LSD worth the 400$ ? I assume my handling will improve alone with some front and back sway bars. From what i read it will handle up to 200 hp. I may one day go to a turbo set up but nothing too crazy just stock. thanks for any input

Hey everyone, I have a car now with a cold-air return on it for my triple webers, 3.1 stroker motor. Runs great, plenty of pull, all good. But, the air box hits the hood, so I've been considering just changing over to individual filters that mount to each carb. I know the cooler air helps, especially as the carbs sit right over the header, but I'm not sure how much. Is it worth building another air box? (The current one has other issues, too, like it leaks, has too many screws, messed up gasket, so I'd have to start over.) Top performance has some filters that would allow me to use my horns still, so the air coming into the carbs would still be streamlined. How much is …

1973 Automatic 240z started making a sound like an unbalanced washing machine only when the car is under load. One of the passengers said it sounds like a dyeing jet engine. I have jacked up the rear and put blocks under the rear to get the rear wheels off the ground. The wheels spin smooth. When the car is in neutral and you spin the rear wheels that causes the drive line to spin unless I hold it and stop it from spinning. If I allow the drive line to spin I hear an uneasy clunking noise coming from the tail end of the tranny. When parked on a slight incline about 10 degrees the car rolls down hill when in park. We just had a mechanic replace the rear bushings, drive li…

I have a E31 head that is is excellent shape and I noticed that it has the bronze valve seats in it, they are also in excellent shape, do I need these replaced with steal ones, or should I not worry about it?

I don't intend on going back to SU carbs so I would like to turn the breather nozzle 90* so I can run a breather hose down the valve cover and back to the firewall. I've seen this done but I don't want too screw it up. I guess I'm going to have to remove this baffle inside the cover to get access, does anyone know what this red compound is that is sealing the baffle and what product I could use to replace it after I'm done? Thanks, Chris

My close ratio 5spd seems to work perfectly except for this very loud rattling/ringing in 2nd,3rd,4th and 5th. I can quiet it down a bit if I hold onto the stick shift all the time, it's driving me nuts, so I've started tearing it down. My Haynes manual is mostly useless but found these great vids on youtube that show the entire tear down and rebuild, they are on post #5 on this thread,http://www.classiczcars.com/forums/engine-drivetrain-s30/45179-rebuild-transmission-tool-harber-freight-6-ton-frame-bench-shop-press.html I love the archives! Here are some pics so far, I know the shop is a mess but everything still has to go in the parts washer before reassembly, …

Car: 1971 240Z with an L28 engine and a "wide-ratio" 5-speed trans. Still got the original R180 diff with 3.36 gears. I've read elsewhere on this forum that: "The early five speed and 3.90 happens to perfectly match the power peak of an L28 curiously" This suggests to me that it might be worthwhile trying to find a 3.9 diff to take full advantage of the L28 and the transmission, but as most of you probably already know, they are not so easy to find. Also, I can't wrap my head around why it would be good to go to the R200, due to extra weight and extra work. There's an eBay seller in Canada who has the R180 with 3.9 gears for about $560 shipped, which is quite high in m…

I ordered the tune-up kit from MSA for my car. I expected (assumed?) to receive BPR6ES spark plugs with the kit, but got BP6ES plugs. Now I understand that the BP6ES are what are called for in the FSM, but I also like simple pleasures like static-free radio reception and clear cell phone communication. I know all of the benefits of using resistor plugs. Are there disadvantages? Why in this modern age of electronics would I WANT to use a non-resistor plug in my car.

Hello all, I'm having a frustrating problem and I wanted to get some opinions. I've searched quite a bit but haven't found anything that either I haven't tried or was relevant. That back story: I have a built 3.1L stroker (not done on the cheap) with E31 head running somewhere north of 11:1 compression. The most runs well with good compression across all cylinders. The head has had a sigfnificant amount of work done. Another piece of infromation is that it has a timesert in sparkplug hole number 3 due to an issue with the head that predates me. I'm running triple webers and Electromotive HPX ignition. I AM running PCV, as using advice from Tony D I created a vacuum …
