eds240z

I tried using the msd tach adaptor 1st and didn't work. I found an old thread that said to use a 280z tach with modification and it worked. Here's the link good luck!! http://forums.hybridz.org/topic/66137-how-to-modify-a-280z-tach-to-work-with-msd-for-free/

Looking for a good rebuildable n42 head.

Thanks for the reply! I'll check the charging system tonight. By the way I'm running a internal voltage regulator alternator if that matters. Also I've been doing more research and I found some people added a diode or resistor. I haven't done this. So I'm reading up on it but I don't see where I need to add this.

Hope someone can help!! I have a 73 240z with L28, Malory unllite, msd coil (that requires no ballast). Tach is working fine. I installed 6al now no tach. So I been reading through threads and found I need a tach adaptor. I installed the msd 8920 and now everything works... So I think!! At idle it works. Rev it up it works!! Redline it still works!!! Problem occurs once I start driving. I would take off and tach seems to work fine than once I get up to speed and change gears it would go back up normally than just drop to zero and stay there till I'm almost to a complete stop. When it drops to zero it's not at any specific rpm or speed. Any help would be greatly appreciated thanks!!

Sorry forgot to mention tach was working great up until I installed 6al and msd tach adapter.

I have a 73 240z with a F54/P90 combo, tripple webers & msa 6 to 1 headers. i installed a msd 6al, unllite distributor, msd coil & 8920 msd tach adaptor. I wired the tach adaptor according to one of the tach threads and I got my tach to work. Here's my issue... At idle its fine and reading correctly. I rev it up still works good. Even rev to red line still working great!! But the problem occurs once I start driving. Take off in 1st up to about 2500rpm then shift to 2nd rpm would go back up normally than all of a sudden drop to zero and stay at zero until I almost come to a complete stop. Anyone have any ideas or had the same problems?? Any help would be greatly appreciated! Thanks!!

Looking for a pair of door panels in any condition that will fit a 73 240z . Thanks!

I'm running the bigger toyota calipers with no problem. There finned S12's with vented rotors. Give a few days and i'll post some pictures.

I basically didnt do my homework!! I just rebuilt my engine(f54 block p79 head) and it worked great! I'm currently running it with triples, headers & ignition. I recently came across a P90 head thinking i would create more hp, but ended up slower then my last setup. I had the head rebuilt, matched ported & polished the intake & exhaust. I was thinking it was a installation error so i did a leak down test & compression test. I found no leaks but I only had 120 psi across the board!! I have a F54 block with stock flat top pistons. I'm pretty sure i'm running the wrong setup. what head should i use to get the most power? sorry , i forgot to mention i'm running a stage 3 cam from motorsports. I was looking around and i saw E88 & E31. Is this correct?

I have 4 15 x 8 2 piece dynalite wheels. If interested lust pm me.

thanks for the info!! where is he located? i thought he was somewhere far because of the phone # he posted.

has anyone ever heard of keycompositesgroup? they sell carbon fiber parts for all types of cars. they have a front air dam & spoiler for S30's i'm interested in, just not sure if the product is of good quality. you guys can check him out on ebay. thanks

you can find everything from motorsport auto zcarparts.com you are looking at ZG flares, bre style spoiler, msa non vented front air dam. not sure on the wheels.

sorry to get your hopes up. everything worked out for me. won't be selling after all. good luck in finding those flares!!!

mixture screw is turned out just a tad under 2

sorry guys for lack of info. i'm going to be working on the carbs this weekend, so i'll find out i little more. as for now, i have 40 dcoe, 40 f9 & f11 emulsion tubes. car is 73. eng 81 f54 block flat top pistons. p90 head w/polished ports. stock head gasket. mallory unilite dist. msd ign & coil. stage 3 msa cam. timing is at 20deg base & 36 advanced. i'm running a carter fuel pump rated at 5psi. i see you guys are running 3psi. iguess mine is too high. i'm running my fuel through a 3 way fuel block that runs a line to each carb. no return. as far as how it runs, what i meant is, car ran like crap before i adjusted anything & exhaust smell was ok. after i made the adjustments it runs better now. runs strong at all throttle positions. it just has a slight hesitation on take off only when cold. but now the fumes is burnig my eyes badly.

i followed you guys through this whole thread and found a lot of good info. still confused!!! my car always stumbled on take off and hard acceleration. but as soon as the rpm's picked up it was cool. then i upgraded my cam to the stage 3 msa and now it hesitates on full throttle. i followed some tips on this thread and did some adjustments. i adjusted the throttle so that it covers the first hole. adjusted the mixture screw and synched the carbs. did not change any jettings. now the car runs strong!!! just feel a little hesitation when i punch it. the onle thing that bothers me now is my eyes are burning from the exhaust fumes. didn't smell this rich before and the car ran like crap!!! it has 40f9 & f11 emul. haven't check the other jets yet. anyone have any suggestions??? what else should i do or change?

i poured oil in the cylinders and compression did not change. so the cam would throw off my compression? if this is normal then i'm just going to disregard the readings. i have the snap on leak down tester and every cylinder stayed in the green on the gauge. i tested with 100 psi.

engine was hot when tested and at wot. don't know calculated compression.

just had my engine rebuilt about 2k ago. i decided to check compression. this is what i got. #1 135psi #2 132psi #3 140psi #4 135psi #5 140psi #6 135psi. shouldn't it be higher? this is a 81 f54 block with flat top pistons, p90 head stock valves polished ports int & exh. msa stage 3 cam, triple webers. eng runs fine. is this normal or something to worry about. oh, bottom end is stock. bores honed and checked, new rings, bearings and balanced. original pistons.

i'm mounting a set of the msa zg flares this weekend. the rears might not be wide enough for my wheels. i might have to go with the bamf. if so, the rears will be for sale. i'll let you know by sunday night.

thanks for info!!!

what should i set my timing at? i have l28 with p90 head. stock block. ported head with stage 3 msa cam. triple webers. distributor is the mallory unilite electronic no vacuum advance. trying to tune me carbs but wanted to make sure timing is correct. i did a search but i saw diff #s from everone. also am i suppose to check timing at 2 diff rpm's? i read at one thread they said check at idle & 3000rpm. if this is so, how do i adjust at higher rpm and not throw off idle timing? don't know much about distributors but seen somewhere about something about weights. does mine have weights? duh..uh... kinda feel stupid asking that ? but don't know much about distributors. thanks for any info!!!

Daeron, thanks for the info. i will difinetly do that before tearing anything apart. now, as for as this zinc theory, is there an additive? i'll do a little search on that. thanks again!!
