   Hi everyone, i just bought some K$N airfilters but after having a look i cant see how they are going to fit over the airhorns. do the airhorns have to come off or do i need to buy some smaller profile ones??? Cheers, Tom.

   Carb coolant hoses

   I would like to know if I can remove the cooling system that loops through the carbs? Actually, the system has already been removed, but I have it bypassing the carbs. This is in SoCal, so cold weather is not really a factor. This is on a 73 240z with 4-screw SU carbs on a 77 L28 engine. Will it hurt if I remove the bypass hose completely, that is the hose running from the thermostat housing to the heater return tube? How can I cleanly tie the heater hoses back into the return?

   OK, I have all the basic knowledge of how the turbo system works, and how to incorperate it with my early Z.. BUT!!! One Part I just dont quite get......... "Timing". stock 76' is 8 deg. (+/- 2 )..... 81'-82' turbo 20 deg... and 83' is 24 deg. 1) Why would you Advance the timing on a turbo system??? 2) Can someone help me understand why with a system that you dont want detonation!!, would you have the spark start sooner?? 3) Is there something about the increased cylinder pressures that slows combustion??? or do I have something wrong in my thinking this out?? Any help appreciated, aZcarbum

   Intake Repairs and Insulators

   Could use some suggestions on the following problems: I was installing 3 screw SU's on an E88 intake on my 73. I removed the N36 intake and was installing the E88 when it happened. Apparently some idiot (insert my name here) let the fuel rail bracket get between the intake and the gasket. I learned that aluminum is not forgiving during the tightening down procedure! I have the original N36 intake cleaned & took the balance tube off the E88 and installed it on the N36. Here are my questions: What can be done with the cracked E88 intake? Is this something that can be welded. The crack does not go all the way around the intake - just about 3-4 inches. If I use the N…

   I just got my 73 240z running for the first time and was underwhelmed with the power. I was not expecting a rocket ship, but I am now wondering what simple things I can do to add to the horse power. It already has a dual webber carb. What mods have people done to the exhaust and what have the results been? Zover

    my car pulls fine through 1st and most of second, but if i'm under load or in third gear my car starts missing at around 4500-5000..... i'm guessing it could be the timing, but does anyone have any other ideas?

    I have a sudden rev limiter?

    Howdy all, Ok, jump in the car, it's warmed up, good response on the throttle and then about 4k the car acts like its got a rev limiter on it, you can hold that beast to the floor and no rev past 4k or so. It acts like it's cross firing. By the way, this is the '74 260, with the triple mikunis on it, the dizzy is a dual point mallory with new points that are gapped correctly...Fuel pressure is fine. It really acts like ignition.... Any suggestions? Thanks!

    Is it possible to order a new bell housing for my 4 speed? Does anyone know of a place that they might carry it? This is really just for cosmetic reasons so that when I put in my engine in the bell housing will look new as well. Thanks

    These pictures are of my current engine mounts. Do they need replacing? If so, where can I get them? Should I upgrade the material? and finally while the engine is out.... what else should I do? Thanks Luke
