Piper

I bought my E31 from Al to use for the street while I was having my track head built. The head is tight and proper. I swapped a stage three cam into and run it up to 7000 RPM regularly. I havent had a single problem with it. Plenty of adjustment in it and the valve job was solid. Quick shipping and good communication. Thanks Al. That was my experience with him.

Anybody on this board?

Dunlop Sport A2 Plus's come in 14" sizes and are one of the best performance tires you will find at that size. I have a set (205/60/14 H rated) on now and they are good for very hard driving. The Michelin Pilot Exalto only comes in a 195/65/14 and is too high a sidewall and too skinny for my taste though its a better compound. BF Goodrich Traction T/A's look pretty good too, they also come in 205/60/14 and are rated higher than the Dunlops.

Oh, I have just never seen one that age with it still on there.

I'm running a bored L26 with a balanced and polished crank and a 12.5 lb flywheel. My compression ratio with the shaved E88 and stock E31 is over10:1 so they are perfect with a hotter cam. If you are running an L28 the N42 would be your best choice for a stock bolt on since it has smaller combustion chambers and bigger valves but a lower compression ratio than the E31 and E88.

I have also seen later E88s with a small E and small 8s. I'll see if I can find one.

emissions? smog pump? this is a 1971 240Z.

I actually wasn't planning on running the oiler bar on the stage three cam. The stage two I was running wasn't internally oiling. To run the internally oiling cam with the spray bar i would probably need a different oil pump and larger capacity pan. I wonder if that would work. You can never have too much oil. Edit: I asked around and I guess you can run the oiler bar with an internally oiling cam using stock innards. Probably cools better than with the block off plates.

Isn't a 12/70 build date considered a 71? Still a good find. Grab that stuff.

E31 on the car right now E88 E is as wide as 8s Valves are pretty big on my E88 (biggest you can fit, they barely made it) and the chamber is notched under the spark plug stock E88 valves for comparison I ran the E88 for a few hundred miles with a slightly clogged oiler bar that scarred my stage two cam and instigated the rebuid with an internally oiling stage three cam (reason why it is dirty).

I have both a 1970 E31 head and a late 1971 (72 model year) E88 head with the small combustion chambers. The E88 is almost identical but has very slightly larger combustion chambers and flows a little better since the valves arent shrouded like the E31. The E31 bone stock produces slightly more power, but I am in the process of doing a full race build on the E88. I had it shaved .050 and shimmed the cam towers. Schneider stage 3 cam and alloy springs as well as 44mm intake and 38 mm exhaust SI racing valves. The E88 is almost done and my E31 is a fresh rebuild with less than 200 miles on it. I'm using the E31 for driving around while I am finishing the E88. After I'm done with the E31 I might be willing to sell it.

Needless to say I am ecstatic! I love this car! It was this one listed in the classifieds here and is a beauty. http://www.classiczcars.com/forums/showthread.php?t=15498
