how many people have their direct ports plumbed on the bottom of the intake manifold? and how much of a pain is it to change jets? how often do you change them?

sounds like a huge pita.... F changin jets on the bottom side,,, there is barely enough room to get your hands down in there.

im imagining needing to do it from under the car. i agree 100% that it sounds like its not very fun. alot of aftermarket mani's are designed with predetermined areas for nozzle installation on the bottom. i know they do it to get the placement as close to the port as they can, and on the top the injectors and rail are in the way. i might have to go with a less than optimal location so i can get to the nozzles for jet changes alot easier.

I'd assume the manifold people are concerned more about their product making as much HP as it can, not how much time you spend wrenching on it.

The other 'problem' is you're hidding some the goodies. How would you feel if every girl did that?

It really depends on where you place the nozzles. I've had them close to the flange and it sucked but the further away from the flange the easier it is and really not that hard. I also had 2 direct ports on the top of a type-r mani. So anything is possible.....

i guess it could be done from under but it just seems a little more difficult being all tightened up fumbling with jets under the car in the darkest region of the engine compartment. youll have to excuse me for looking for the easiest way of wrenchin on it, i am a mechanic after all.

alright Jeffy, you are going to have to post a full size of that Avatar ! my eyes arent that good ! haha

jeffy

sorry, no full size of the avatar. i cant even have it as an avatar oh well. cmon for info on the original topic!

I have my direct port plumbed to the bottom of my manifold for stealth purposes and it is kind of a pita to change jets, so I just don't change em.

I had a direct port on the bottom of my AEBS intake manifold. Changing the jets really wasnt all that bad, afterall, how many times are you going to have to change them?

Why don't you see if you can make a spacer that goes in between the intake manifold and the head. I have installed a secondary fuel rail on a eclipse. That way it would move the jets to the top of the manifold and make life a whole lot easier. I am sure you can find flanges on the internet and you can just drill and tap the top of the flange. Or if you have a local water jet in your area you can just take them the gasket and they can cut you one out in any material or thickness you want. But its up to you and I am sure you don't need to change the jets very often. But GL with the project.

jeffy

well, i plan on working my way up from 75-150. so i guess ill be changing them a minimum of 4 times. i just like to make things as easy to work on as possible.

i don't have any good pictures of it, but I have my jets plumbed on the bottom of my car. It took every swival socket/wrench I could find to even bolt up the damn manifold. Running a victorX which has short runners, just doesn't give alot of room for anything. Then again, I'm running turbo + nitrous, so its not like I'll be changing the jets that much, so the 80 shot is just fine.

can you see it...its all under there. changing jets is a pain in the ***. but it does look cleaner.

so the general consensus is that under the intake is a huge PITA but at least its sneaky.
