  1. Used to be an old celica around here with a blow thru efi setup i think (may have been carb but rumor has it efi?)

    It got the nicknames vacuum cleaner and street sweeper.

    Because it constantly boosted against the closed throttlebody and had to vent the pressure to atmosphere.

    Unfortunately due to that it sounded like shit and earnt its nick names.

  2. Spoke to a guy i worked with and turns out i was kinda wrong. They weren't a factory item just the company that had the fleet of cars had same issue as you in a few cars and fitted aftermarket oneway valves.

    Unfortunately whoever chose them used some weird design instead of a normal ball and spring design. (Easily found on ebay)

    The rubber diaphragm unit they fitted was as unreliable as a flymesh condom.

    But. You could do the same.

    But a decent "check valve" or oneway valve and fit it just before the fuel rail.

    It could very much fix your issue. 

    If not id look at the pressure reg.

    Then the injectors. (This would mean its flooding the cylinders or cylinder and requiring you to flush itbout before it fires, but i tending towards oneway valve or pressure reg )

     

  3. I think it was an 80's nissan?? Was many moons ago now.

    Most modern cars utilize the pump as you said.

    Try what i said.

    Click the ignition "on" wait about 4seconds then crank it.

    If it fires straight away then it narrows it down to a fuel priming issue.

    Your mechanic will probably do this same test anyway. But possibly charge you to do so?

    Its quick and easy to do

  4. Ive seen some cars with a one way type valve that sits near the pressure reg.

    They were a rubber diaphragm setup that used to perish. If your car has one it could be this.

    One way to test is before starting turn the ignition on for a few seconds to allow the fuel pump to "prime" up the pressure etc. Then crank it.

    If it then fires straight away you have oneway valve issue in your fuel line.

  5. Yep because dellis are so easy and cheap to tune compared to a single 4brl...

    He is talking supercharged. Not NA.

    Big difference. 

    But hey in not the one thats going to be paying for ALL the extra needles, jets, chokes etc to tune them so go for it.

    But you will note.

    I said efi or a 4bl...

    Id take efi over shitty carbs any day. 

    Plus was zero mention of what engine prior to what i said.

  6. Usually because the ones that try something different/new/untested aren't working with a very tight budget.

    You're going to be up for a large wad of $$$ just for jets, chokes etc for the carbs. And you may need several different sets til you get it tuned right.

    Having pulleys made etc isnt cheap either.

     

    Im all for trying something different and new.

    But not if im on  a super tight budget.

     

    Best of luck which ever way ya go.

  7. On a tight budget and dont really know what your doing or if it will work...

    Answer.

    Dont do it.

     

    If you're determined, go for a tried an true setup.

    Supercharger and efi or a single 4brl carb.

    Sell the dellortos to fund your project.

    .there's usually more to it than you think.

    Blower support beackets.

    New manifold. 

    Pulleys 

    Cyl head Decompression plate.

    Etc etc etc

    Thought it could be usefull for people wanting to door knock too, which is where the maps come in handy.

    Fuck i hated it when google released street view etc.

    Had every scum wanker knocking on my door about cars in my front yard (my daily drivers) they'd come from other side of town cos rhey saw it on google etc.

    Also started getting people asking about cars in my backyard due to google maps.

    Absolute pain in the ass. As it was only ever people that actually drove past.

    Now its everyone that trolls google maps etc
