[What is this wire?]

That looka to be an Ignition noise suppressor to limit noise in the radio.

[Luxury Mercedes Benz scam? Need Help]

To me it seems that the Dealer/Seller needs to pay for that extra 5K Miles. You had paperwork in writing and you didn't get what you paid for. If You feel strongly about what you wanted and what you didn't receive, ship the car back.

 

Bottom line is its all up to you.

[Tuning questions]

Yes, 11 or 12 VE at idle is low. Seems it should be closer to the 30-35 VE Range at idle. 12.5 on your Wideband, seems to be what these engine like at idle. I can't read your MSQ on the laptop im using though.

[L28 to L28Turbo]

To run Megasquirt: G.M. Intake air temp senor. 240sx or any 1995 on up Throttle position sensor. The older TPS sensors are just an on off sensor. Wiring harness from megasquirt ecu to engine. Relay Board or make your own relay Board. Laptop to tune your engine.

 

Yes with Megasquirt you can run the higher Compression engines no problem.

[If you have to do it all over again....]

2JZGTE

[How awesome is your wife?]

Seems like you have a good one there.

 

Your gonna be rubbing them cold feet for quite a while, Maybe thats what the Fast Orange IS REALLY FOR.

[Help, Motor is Misfiring]

If the mis is constant then as was suggested above, You have to narrow it down to which cylinder is causing the mis. If you can get to the injector connectors easily. Remove one injector connector at a time and then reconnect it, to see which cylinder with the F.I. connector removed, does not change engine rpm at idle.

 

The cylinder that doesn't change is the problem, Then try swapping coils, plugs, injectors and so on.

[whats needed for efi?]

Intake manifold, Throttle body, Injectors, Resisters for the injectors, To Run Megasquirt, Fuel pump, if yours is no good, a G.M. Intake airtemp sensor, 240sx Throttle position sensor or any mid 90's Nissan TPS Sensor, Wideband o2 sensor and gauge. You will have to decide if you want to use a Distributor or A Crank sensor of some type to get spark.

[WTB: cheap 280zx turbo exhaust manifold]

I sent you a Private Message. Check your messages.

[Cannot insert the key and car stuck on ON mode !!! Help]

In the mean time, just disconnect the negative battery cable until you can fix the lock cylinder.

[Someone broke into my car]

JOKING. Come on ZERO, Read THE OWNERS MANUAL. lol Same function in my 97 Maxima. 1990's -2000 technology. Not 70's Technology. LOL Joking with ya.

 

I'm a Nissan Tech and You have no idea how many customers I get a week, who Don't or Won't read there Owners Manual. I Print the pages out for them to answer there questions.

[Someone broke into my car]

Your car should have the window function, that puts the windows down with the key remote. Im going to bet the door lock cylinder has that same function. So when they messed with door lock cylinder the windows went down.

 

Wiring may have been messed up if they used a slim jim to try to open the door.

[280z Turbo Missing.]

Try disconnecting and reconnecting the ECU. Check for good spark at each cylinder. Check all the injector connections. If a cylinder is the problem, check for no spark, no fuel.

[Running issues l28et]

Check if it is losing spark or has spark when it won't run, Don't throw parts at it. Atleast check for spark and fuel first. Always check the Basics first. No Spark or No Fuel, NO RUN.

[LED's light up with stim but not when installed in Car]

Are you sure the relays are good?. Are you sure all the fuses are good?. Check, Double check, triple check, and then check again. Many people have chased there tails with electrical issues, because they won't check fuses multiple times.

 

Is the Ignition switch good?.

[Car won't rev past 3000rpm]

Have you tried comparing tunes from the Map sharing threads?. Try looking for one that is similar to your setup and see if they are close.

 

Is your wideband showing a good ratio when the engine is cutting out?.

[Tell Tale Exhaust residue??]

How was the engine runnning before you pulled the manifolds off?.

 

Also make sure the exhaust manifold is not warped at the ends. #6 port on the manifold will usually warp, if that end exhaust manifold bolt breaks. If it has been driven for a while like that its best to check it with a straight edge. You may either have to shave the manifold down or replace it if its warped.

 

Have you changed the fuel filter yet?.

 

Usually white exhaust residue means the engine is running lean, The white residue on those ports does not look right. The #4 exhaust port actually looks brown to me and that looks normal.

[260z with chev v8 twin turbo]

There is a build thread with progress pics, of a Chevy V8 with Twin turbos on this site. I don't have a link but you may be able to ask them what trans they used.

[im BACK!]

I watch all your videos, Most crack me up. And yes that will be one fast GREEN Z.

[Wastegate Actuator Dimensions]

What turbo are you using is my first question?. If stock, see if you can find a stock actuator.

 

Some of the adjustable actuator arm wastegates, would probably work for you, from how your explaining your setup. The rod adjusts so the actuator opens sooner or later.

[The reason to KEEP EGR if using modern factory EFI]

Good Post,

 

I am wondering why the check engine light didn't turn on, or maybe it was on. OBD2 systems will read lack of egr and set a code, Atleast the imports will.

 

I work as a Nissan Certified tech and the light will turn on with a 95 and up model.

The 95 and newer trucks will have an egr code. Pre 95 will have an engine miss at 2000 rpm. Cylinder misfire code, Too much egr at a certain cylinder, means egr tubes in the intake are clogged.

[Any MS Gurus in Socal?]

Have you tried copying a tune based off of your setup, in the Maps Section?. Just look for one thats similar to your setup and copy it. See how the engine runs with that tune and then you have to tune your engine from there. Thats what a lot of people do.

 

Do you have a wideband? If not its harder to tune but not impossible. Just have someone ride with you and you tune on the fly.

 

Megasquirt also has a program that helpe you tune your engine.

[I need one 440cc 7mgte injector pigtail]

Have you tried going to your local picknpull and looking at 80s-90s Toyotas ?. Connectors may be the same. I know the Cressida injector connectors are different. But not sure about the other models. Just a thought.

[L28 NA Fuel Injection Upgrades.... Confusion]

You can use stock zx turbo injectors as an upgrade, you may need to adjust the air flow meter spring though.

[L28ET WEIRD COMPRESSION]

Have you performed a valve adjustment Yet?. I recommend doing that first and make sure everything looks good on that cylinder, valve springs, valves not sticking, Camshaft lobes. After doing the adjustment check compression in that cylinder again. If you have no compression change, I would add some oil to that cylinder. If oil raises the compression number, then the rings or possibly cylinder is the problem. If the compression number stays the same after adding oil, then you have a problem in the cylinder head, valve, or guide.

 

Keep us posted.
