So --> I got up bright and early this morning (yeah ok, so it was 8am) to do all of teh prep work on the engine and trans removal from my parts car for insertion into my race car. I have to say, Nissan/Datsun engineers made this as easy as a small block in a 69 chevelle. I had room to work, the only stubborn bolts were on the exhaust (no shock there).. I cut the down tube off, I will just re-weld it later... I was ready to pull the engine at 12:30 -- so I ran off to pick up my friend and the hoist... Now -- the fun really started -- we had the hoist hooked up, and the engine and trans were coming out and it was about 3 oclock! What an efficient morning I was thinkin…

Anybody have any good ideas or tips on removing the carbon build up in the combustion chamber and ports of a head? I'm trying to clean up my E31 head and I need to remove the carbon build up on it. I have tried a wax/grease remover (like PrepSol) which works, but it takes lots of rubbing and lots of time. Plus I can't reach very well into the tight areas. I know a screwdriver would work but I'd prefer not the scratch up the chambers. I guess I could always take it to a shop and have them dip it, but that would cost money I don't have right now. Any DYI tips or suggestions?

My 0 to 30 time is horrible! I am wanting to do something to my car to make the low end torque better and have a great start to my car. It is an automatic and I am thinking of getting the fuel injectors cleaned. What do yall think I should do to make the car faster from the start. Thanks

I've seen rebuilt cam and rebuilt rocker sets for sale on ebay. Anyone know how well these "rebuilt" rockers function? Longevity, etc.

well, today was the first day i have been able to drive my Z, and it was runing a bit rough. Anyway, when it is cold it misfires quite a bit, but after it warms up, it misfires less it seems. I also took it into DEQ and it failed hydrocarbons by a factor of 3X (OUCH!). this is not a cali Z, and never was equiped with a cat (nor will it ever be equiped with one if i have any say in it). Anyway, i began to figure that it might just be running rediculusly rich after the DEQ results, also causing it not not/misfire when its cold (and as it heats up it gets enough heat to ignite the rich mixture and is happy). Would an overly rich mixture cause these problems? how can i adjus…

I recently installed a 1978 (n47) head, fuel injection & electronic ignition on my 240z block (with flat top pistons). Both the engines ran good before the transplant. I can't get the new 'hybred' to fire. Shouldn't the distributor on the 280 be at a the same installation position as the 240 engine?? I am sure the crank/cam timing is correct - set it by the(240z manual) book. I have the injectors working fine - I have excelent spark with new plugs & wires. Doesn't that point the finger at the spark timing - I set that by the book (240z manual) also. Any ideas would be helpful. Thanks guys - Jeff

Before all the flames start coming, let me just start off by saying that I do know what it means to rebuild an engine... My question is more dealing with an engine overhaul. What is typically done to overhaul an engine ? Where do you draw the line between the overhaul or rebuild decision ? As best as we can figure, our '78 sat for 5 years before we bought it back on Aug 2001. When you drive it, you can tell that the car isn't giving you all it has. I plan on replacing the exhaust system soon, but the engine needs some attention as well. How do you determine what would be best? Beside the difference in cost, is there anything that would make one option more attractiv…
