I finally got my new turbo injectors in. but i forgot, do i need the turbo fuel pump now? Are they the same or not? What happened is i started it up and it worked pretty well at idle till i tryed to rev it up then it cuts out.

 

No one coulda predicted that. I'm sure it's running too rich, not too lean. Pull a spark plug & look @ the tip.

 

no it smelt pretty normal but i have lots of ignition work now. i think my non turbo fuel pump cant keep up with the turbo injectors so it makes it to lean at higher rpm's.

 

Not a likely cause... did the car run with the stock injectors?

Pull a spark plug & look @ the tip.

 

ya it did till they clogged but i changed filter and gas and everything but then wanted the turbo injectors. ill check the plugs right now one sec.

 

the plugs look fine. i think i probably have a clogged fuel filter and might need the turbo fuel pump. But back to one of my questions does the turbo fuel pump have higher flow than the none turbo?

 

Slightly... but it would only make a diff under boost, which you don't have without a turbo.

 

The injectors are too large for your application. You might be able to get your Z to run right by tweaking the afm, but otherwise you need to get a set of naturally aspirated fuel injectors. A brand new filter doesn't clog unless you got a metric ton of debris in the gas tank...

 

Dude, a half dozen people here have told you not to use turbo injectors on your NA motor. Adding more spark will NOT make your overly rich motor run better. Spark doesn't add air intake volume and neither does a cold air intake or a 2.5" exhaust. The only way to get more intake volume into your Z is to do head work, upgrade the cam shaft or bore/stroke your block. Even then, your intake manifold will be the limiting factor on a fuel injected L6.

Short of that, the best way to get the most performance out of your car is to make sure it's running in absolutely perfect condition. Clean every electrical connection from the ECU to the front of the car to make sure you have no "extra" resistance in the system and replace every vacuum hose to make sure you have no vacuum leaks.

I know it's not very "cool" and you can't really brag about it to your firends, but at that point, you'll be able to outrun nearly every Honda you come across.

If you still want more, then follow the first gen 300ZX (Z31) ECU/MAF swap instructions which will give you much more accurate air/fuel management making the car run even more efficiently. I'm not sure how much more power you'll get out of it, but you'll definitely get better gas mileage and your motor will run even smoother than with the 280ZX ECU. Oh, and you STILL DON'T NEED TURBO FUEL INJECTORS...

 

I've been in auto part sales over 8 years and I've seen less then 2% of new fuel filters that are bad (low or no flow). I saw a new filter that was on a car for less than a day and it was plugged up. So yes the fuel filter could be bad... as for the fuel pump, go to http://www.partsamerica.com/default.aspx and put you car info in and see if it works on both...

 

is anyone who read the other thread about this surprised that this thread now exists. ditch the turbo injectors.

 

i ROFL'ed like literally, it was just a huge "WE TOLD YOU SO" screaming in my head. and then he tries to say its not the reason why.... you have injectors flowing 25% more fuel than the stock ones with no other real upgrades than spark maybe intake exhaust? its not going to fix your A/F ratio. we welcome you as a member. we arent trying to scare you off with our some what teasing posts now. but tis pretty ironic and you just need to get stock non turbo injectors.

 

keep an eye out in fs:
cheap zx - doesnt run.
now you have bought the turbo injectors why not buy the rest of the turbo gear to make it all work?

 

Well good news i looked up part numbers and the turbo fuel pump and fuel pressure regulator are the same in turbo and no turbo cars

 

Okay, but if your getting 25% more fuel with turbo injectors...

 

Get Rid Of The Turbo Injectors!!! That Is Your Problem!!!

 

ya i know but it runs and not bad its just gettin more food then it should haha. Im going to tweak the afm maybe. But i really want to cam it with like a stageII or stage III cam and port match the intake manifold to the head when i get the 240sx throttle body. It will run great then with the injectors i dont care wat u say then. haha. i just need like 1 more weeks pay to get it all done up.

 

Is there something im missing here?!?

 

hehe ya. Im crazy! But isnt like my 1,500 that i'll have all saved up by next week wont get me the ld28 crank and wat not . that's why i bought injectors in the first place cause im itching to kno how it will run with it being stroked and turbo'd

 

Logically if you want to know how a stroked turboed engine will run with turbo injectors, then put them in a stroked turboed engine. What are you learning about how a stroked turbo engine runs w/ turbo injectors if you put them in a stock n/a engine????

 

i put them in cause i got them. isnt like the cars my daily driver. The cars is going in the shop soon anyway hopefully. i will know how the work in a month or two.

 

At this rate your stroker motor will be short lived...

 

haha. probably still last longer than a honda with a fart can

 

Dude, I think you're missing point. Even with a mild camshaft, you won't be pushing as much air as you think. Like stated above, you need head work and a different intake manifold before you gotta worry about fueling issues. Port matching will not make a significant impact. The only thing you'll end up with is an n/a Z that has a lumpy idle and sputters around town. Not too much fun to drive. You could get the same results by just retarding the timing, disconnecting a fuel injector and running on 5 cylinders... If n/a performance is what you want for the time being, follow Shady280's build as his n/a machine runs great, I've seen it first hand.

 

actually, if hondas do anything well, it is that they last forever.
