once you know bore size and desired compression ratio you want I.E. head volume and piston setup domed, flat or dished.once that's done, Its all about how much air and fuel you can cram in there. Cam and air fuel delivery ect.. If your talking about the flat tops then yes ditch em. Use a p90 or N42 it really doesn't make a huge difference. Hell a ported E88 would do it. But you eventually come to Carb Vs. F.I. I prefer carbs "less wiring and hassle" however each has it's perks and draw backs. throttle response and fuel economy and so on. I personally would run some flat tops with a N42 block decked and head shaved and shimmed and ported topped with a cam with a long duration. Should be good enough... I think

I really dont have much to say but wow what a waste of a 70'

hey thanks for the info the fuel pump was bad when i took it apart the brushes were so worn they were almost non existant so we replaced i made a little progress im now getting fuel to the filter but not to the rail i get spark at the plugs. under the passenger seat there is a plug that goes to a little gold colored box then to nothing but then there is another plug that goes to nothing at all its just sitting down there. the new fuel pump runs when we try to start the car but doesnt if the ignition is just left on??? i was told today to check the vacume system so thats what im going to do. Do u know where the most likely place is for a leak i dont know where to start?

hey guys i was looking around on here for some type of reference my little brothers 280 wont start the fuel pump was bad so i replaced it but we're still not getting fuel to the injectors not even the filter i spoke to my father he told me to bleed the fuel injection system???? and none of my manuels speak of this do any of have any idea on how to do this???

my 260 was produced in 9/73 vin rls30-005573

alright im not alone i am also in the middle of a restoration of my early 260 and ive come across this same problem you can order the rubber inserts from motorsport but watch the pocket book they are incredibly expensive given that they are made of rubber you may not be able to find them on there website but if you order there catalog they have every little thing you could ever want happy hunting

the hole is right behind the rear tire on the passenger side its about the size of a hot dog 6 inch long and 2 in wide ill get the pic on here for him ive told him we're doin the whole wheel arch there are pin holes all over it

thanks alot u guys i think im gonna stick with the n42 i have a buddy who owns a machine shop and owes me some money so we'll do it that way

hey guys im in a bit of a pinch i just recently warped the head on my 260 and in need of an answer i currently have an n42 head on that now needs to be shaved or should i just rebuilt the original e88 im looking for performance and dependability ive heard alot about the n42 heads and that the compression ratio is changed when put on i guess what im after. is it worth shaving the head and putting it back on or should i just use the e88?? :paranoid:

If you are interested in a 260 there is a dealer here in santa fe NM that has an all original 260 that is a dark emerald green black interior it needs the tach cable and an oil pressure sending unit other than that its a great car 113,000 original miles there is one little crack in the console and that is it he is asking $5,495.00 it is definitlyworth looking into his number is 505-820-6929 ask for dave well anybody can help really im too busy restoreing my 260 to pick this one up well happy hunting and it is a later model with the larger bumpers on it

Hey im havin some trouble i have a 74 260z its an early one and i have an emergency start button that i would like to hook up and ive tried finding a wiring diagram that shows where the wires are coming and going to to properly hook this button up im starting to wonder if i even want to hook it and what exactly is the buttons function does it route the power in the car to the starter im a little lost up plz help

I would take them to the shop. I did this to my 260 and if you dont take your time you can end up cracking your pistons; nice and SLOW thats the key
