i just put some hydraulic jack oil in mine, put in the cartridge/gland nut, and wiped up the mess..... every mechanic i talked to gave me a weird look when i asked them and said "it must be a Z thing, i don't understand what those guys were thinking." guess it is...?

dellorto's were like rochester or carter carbs over in italy.... DHLA 40F or H's were oem's on many cars over there.... they are also the ones the dude on ebay sells (i have a set of F's on my Z)....

mikuni/solex, weber, and dellorto all mount on the same manifold, while dellorto and weber share the same airfilters, and mikuni is different.... be careful putting triples on a stock motor though, i've been chasing a flat spot all last year that i just can't get rid of.... i'm running dellorto 40's on my z. the only conclusion i can come to is that she's over carbed, or at least, that's my justification for looking for just the right cam and exhaustROFL

you could always go american old school with the shifter... bend it somewhere under the boot so that it is angled to the left and back, like on all the old 4spd muscle cars. i was debating about doing that to mine... might need to lengthen the rod a bit though. be sure to practice first to get the position 'just right', or shifting will be VERY uncomfortable!!!

the injectors leak by not closing all the way. this can happen because of a bent pintle inside, dirt, or both. when they don't close, they constantly leak a small or large amount of fuel depending on how open they are. the fuel pressure regulator can also be bad if the spring inside has worn out over time, or the diaphram inside has gone bad. if the spring inside is worn, too much pressure is going to the injectors, which can cause a rich condition. if the diaphram has gone bad, it has ripped, which would allow the motor to draw fuel through the vaccuum line that attaches to it, causing a REALLY rich condition. if you have a fuel pressure tester, hook it up, and i believe the pressure should be around 33.6 (?) psi.

meeting up would be great. pm me with your phone number, email, or something, perhaps we could work something out on a weekend!

http://demo.cs.brandeis.edu/postscript.dump/Ltronic/Injection.html this site gives you all the internals of the jettronic system, and some tricks for more power. there are VERY few things you can do, such as the 240SX T.B., you can adjust the a/f ratio by using the adjusting screw on the side of the AFM, you can loosen the spring inside so it opens quicker, add a potientiometer between the temp sensor and the computer to make it think it's a bit cooler to dump more fuel.... etc. are your injectors leaking? when i had EFI before the carbs, i was getting around 20 around town, 24 or so on the highway... or your fuel pressure regulator? are you blowing smoke out the tail pipe like you're running rich?

hello! i am leaving for school at wyoming tech (the blairsville campus) next week, and will have my Z down there for a bit before she goes to sleep for the winter. i'm just wondering about any Z gatherings around the pittsburg area. i know it's the end of the season and all, but, she's too much fun to put away!

looks much better than my floor pan! i wouldn't worry too much, weld a small panel over it, and use por15. is it just me, or is it almost always the passenger side that rots out with the floor pans???

he wouldn't happen to have any '70 superbee's there, would he?

like guys have been saying, there are many schools of thought on it... you could go 'old school', getting the engine, suspension, brakes, interior, etc. all said and done, just to strip and paint it. OR you can take it all apart, paint it, rebuild it while it's all apart, and when she's put together, you'll have a georgous car. the path i chose was to park her, strip her clean of EVERYTHING paint, rebuild, put togehter. if i were to do it again, i would do it the same way. get her all together, then work out the bugs. in the end the choice is yours, but, i believe that this method yields less down time in the long run...

my dad has an 87 fiero gt. that car is a BLAST to drive. i almost bought a bunch of them, but, then found my Z:love: but, i would still get a kick out of building up a fiero. mid engine cars are fun to drive, but, careful! they don't care which way is going forward, as long as one of them is!

my absolute dream car is a 1970 Dodge Superbee in go-mango orange. this could be due to being raised hearing about the one my dad used to have... 440 cui, offy dual plane tunnel ram, twin 650 center squirters, 330 intake/exh duration .550 lift cam, wild gears, fairbanks racing tranny..... *drool*

i used to run high test when i first run my car (i listened to the manual... what do engineers know anyway?) last summer. but, then to save money, i decided to try 89, worked great, no loss in performance. i even ran regular for a while (stock 78 with EFI) with no weird noises. when i went to carbs, it didn't like the low test, so i went back to 89. a stock fuel injected Z runs around 8.3:1 compression with the aluminum head. you have to be trying REAL hard to get her to knock or ping with that sort of third world compression ratio. my timing was set at about 10* or so, but even advanced a little more, didn't knock, just had a nice little backfire on downshifts from higher revs. not bad ones, but, they still sounded pretty cool!

hey guys! sorry i havn't been around in a while, work and such sucks!!! well, anyways, allot of u guys from the northeast probably heard about the north east Z car adventure in syracuse this past weekend.. i entered my 78 in the 260/280 street mod class, and won second! finally, all the hours in the garage and listening to my mom and lady friends b***h at me pays off! i won second!!! man, there were some beautiful Z's there, and plenty of ideas for me to soak up and enjoy once i find the money! the auto-x was great on sunday as well. the exit i made with my buddy's was a little overzealous (read as LOTS of tire smoke... :stupid: ) if anyone that was there reads this, sorry, got lost inthe moment! well, time for a cruise night, hopefully i'll be around a little more now!

the mikuni's are great as well. they were the original and still the current NISMO part for these cars (japanese car, japanese carbs!). my buddy has them on his 240, and i've noticed that they are VERY temperature sensitive and he has a roungh time keeping them consistent with the weather changing... and that's a pretty bad problem to have here in Rochester! you can go through all the seasons in a day if you want!

i have dell's on my 280 (DHLA 40F), and they were ok until i turned out the chokes.. now there's a real bad flat spot i can't get rid of.. tried drilling out the mains, havn't done the idle's yet. i also have the accel. pump at full throw. needs some more tuning. i also need emmulsion tubes, so if anyone has some, let me know! the only place i can find parts is in england. there's a company called CB performance in cali that has some parts, but, not the ones i need right now (but they do have rebuild kits, air horns, filters, etc.) you can get the 40's on ebay for about 220 including shipping from italy unless prices went up in the past few months... there's always the same guy selling them, and he'll bend over backwards to help u out.

i don't know about webers, but on dellorto you can change the inlet needle size. if you just aren't getting enough flow, try using a slightly larger needle...

try raising your floats so that they hold more fuel.. either that, or use a higher volume fuel pump such as the holley 'red' pump along with a regulator to tone it down to about 3 psi.

what's your fuel pressure? mikuni's should be running about 3 PSI at the carb furthest from the inlet.

i like that concept better than the production version.. holds on to a bit more of the S30's than the new ones. i mean, look at that opera window! classic....

the dash in the car w/gauges is in MINT condition from what i saw (no cracks above the gauges, still has all it's luster, etc, etc.), and there is another dash out of the car that is also in great shape, but without the gauges. i already promised the tach (if it works) to my buddy here, so that wouldn't be included, unless you want a bum tach.... would probably be pretty expensive to ship, i live in Rochester NY if you'd rather pick it up.... are the hubcaps you are talking about the ones with the "D" in the middle of them? i'm willing to ship to you out there, but, it would probably cost both arms, and most of your right leg! i'll post pics of parts if people would like...?

i've only been a member here a few months, but, i have learned allot, as well as hopefully helped a couple of u fella's out! you know the old saying, 'when you get inside of a Z, a Z gets inside of you!' or, one of my favorites by mr. K himself, 'any car can get you where you need to go. but, a special car can get you there with a smile on your face!' i personally own a 78 280Z. although, soon, she will look like a 240Z from the outside except for the badges (changing the bumpers... went to carbs.. etc.)

that's a pretty good question... i definatly love my Z to death right now. she's a sort of performance restoration (even with italian carbs...) at the moment. although, at some point in my life, i would like to own a factory original 240Z (preferably one of the first 1000 off the line... but any 1970 would be cool), as well as a Z with a blown 327. i personally think that the 327 "sounds" more the part than a 350... a nice high winding V8, know what i mean? although, at this moment, i could never picture parting from my Z (granted, i am only 19). she is my pride and joy, hands down, no questions asked. the EX girlfriend didn't like the Z though.... she (the Z) got more attention than her, or so she (the EX) said. but, oh well, that's life!

hehehehehehe:love: !!!!!! wow, i forgot how much fun these things are to drive! that's what has been causing my absense, out playing around! well, a small update for everyone.... my father and i bought a 73 240Z that we were planning on dropping a 327 into, but, the passeneger side is GONE along with the strut towers. so, we are parting it out. interior is immaculate, and includes an extra dashboard, 15" alloy rims, extra head (E-88), hubcaps, a bunch of other stuff. anyone need anything? the doors and fenders are clean, the doors are from a 71. if anyone needs some parts (other than the rims, 4spd, and a couple of others that i am keeping), let me know, and we can work something out. otherwise, parts are going onto ebay!
