i switched out my whole 79 chassis and engine harness to 82 gl . i have a fews problems that i know of. first what do i do about the cyl head temp ? also what about o2 sensor ? and 3rd when i turn the key to on the fuel pump kicks and stays on as long as its on on . and if i run the 79 ecu the fuel pump doesnt go on at all? hope you guys can help

cool i just want something to play with while i am building my turbo setup.

it would be going on a n/a engine boosting no more then 6-1/2 psi.

what would be the issue running it i am just curious.

i have been looking around for the stock turbo the tb03. which is a t-3 from what everyone is telling me. my issue is this i was at the junkyard and found a 280zx turbo the exhaust manifold was gone but the turbo was there. well half of it. the exhaust side was there. and it looked small. compared to the pics i have seen with the turbo still on the block. now i have a turbo already. but it says it is a t28 but the exhaust flanges look the same what would be the benifits and draw backs of running this turbo. it is the turbo in the pic on the left. thanks for the help guys.

ok issue solved. it was the cylinder head temp sensor. and the odd thing was it was not connected on my old engine and this one did not have the sensor. so i got the sensor from mike's z shop 20 buck and she runs good

i dont have any fuel coming out the fpr. and i am going to check the 2.5 quart test

ok i hope this helps some i made a video. http://videos.streetfire.net/video/my-280zx-issue_683051.htm hope this helps

only thing i have not done yet i am waiting for my buddy to bring a tester by.

yup i am tired lol. i am just really confused cause the old engine ran fine with everything and the new engine is all crappy

fsm sorry lost on that one or i am just really tired.

if that was the case how could the frp go bad in a week plus it has a new vacuum line to it.

ok i switched the engines because i kept breaking harmonic balancers. the keyway notch has a 45 degree smash in it. the last time i fixed it i used quick steel and let it sit for a week and it lasted 6 months. it ran like a champ. no issues what so ever. the new engine is out of my rusted out 82 280zx the issues with it was it ran like crap. i tried to fix it but it just bogged and the electrical on it was in so so shape. so i put it in my good shell. i used the dizzy and the intake manifold from the stock engine. all the electrical is the same. i did not change anything. the only major change i did do was replaced every fuel line on the intake manifold with newer fuel injection line. and replace all of the water and vacuum lines. i am running msd street fire wires. new g2 ngk plugs. i did not switch any sensors on the engine. some of the connectors were a little corroded. but i tried to clean with a paper clip and put die electric grease on it. i checked all of the fuel injectors one by one while the engine was running. all sounded good but i think i need to clean 1 and 3 alittle more. they work but are tempormental. all i run is 91 octane from 76. oil is 20w-50 vr1 valvoline and a k&n oil filter. oh i put a new water pump on it. and the dizzy that is on it is from the stock engine. i am lost. thanks for the help. sorry had a brain fart. so i dropped the engine in this morning and connected everything up. and went to turn it over and it just turned over. so my brother put some gas in the intake and it started and ran for a little bit ( like 45 seconds) but it was at 2g on tach and wot. so we played with it. checked spark checked to see if the fuel pump was working and everything was. so i am starting it and it starts to run but 50% throttle it was idling. so my little bro pinches the fuel line and boom it runs normal and is at 4-5g on the tach then bogs. (he is pinching and releasing the pinch really fast.) but while it is un pinched it looks like it is running super rich. it was smoking a bit out the exhaust. so he decided to remove the fuel pump relay and it idles perfect and i am like wtf how is that possible. so i try to rev it and it wants to die. so i barely start opening the throttle and it starts to rev at like 15% it is at 5-6k on tach so i am lost. i have played with honda and old muscle cars but never had a issue like this. my brother thinks it will bite me in the butt. but i dont know. i hope this helps some. thanks guys

the car ran before just fine. and i am using the im and em off of my old engine. cause the engine that is in the car now did not run right in the donor car. so i decided to run all of my stuff off my old engine

i have a 1981 280zx that i just switched the engines on. the old engine kept breaking harmonic balancers. now the new engine only runs if the fuel line is pinched or the fuel pump relay is removed. i have replaced all fuel lines and vacuum lines on the intake manifold. i am at a stand still on what it can be. thanks for the help

it is 5 speed stick. and a 2+2. there are 2 different clutchs. what is suppose to be in the car stock the larger or smaller one. thank you

i have been search for 3 hours now and only figured out this far. 5 wires go to the afm. 25/32/33/34/35. wire 25 goes to the air temp sensor. on the turbo model the yellow with red stripe is the signal wire. here is the link. http://www.mygen.com/users/dbruce/myz31/JWT%20450%20Kit.pdf. i wonder is the lt green with red stripe is the signal wire for the non turbo. is there anything i should look for or a certain way to test. i think the signal is to be similar to the tps signal wire. ov-5v , closed throttle - wide open throttle. thanks for the help and info

i have search everywhere and cant find my answer. what is the differances between 1981 front brake assy's and 1982 front brake assy's? i know the differences in the rear but the front is bugging me. thanks guys.

yes but i want the turbo vent on the passanger side also hence the mirroring. i am going to go to beta in the morning they are like 20 minutes from me .

my only issue is mirroring the turbo vent

i know what you mean. i can see it in my head but dont know how to output it.

it is along the lines of that. but i would like the zxt hood. mirror the turbo hood so i have the turbo vent on both sides with a nice cowl.

ok i have not found much on 1981 280zx carbon fiber hoods or fiberglass. so i am wondering if i able to tell someone what i am looking for. how hard would it be to make it?

has anyone done this yet and what is the plus side? i got one for free but cant find any wiring diagrams for my car.

hey i am lance. and i have 2 280zx 2+2's right now but one is parts and one i am fixing. i will post pics of my red s130. in the last 2 pics my brothers 280zx is behind mine i will have more pics coming since i have done some major mods
