EFI Intakes for ferty hersers/12 hundri sicies

[Chickensoup]

Dauz, thanks for the links. I checked them out and everything looks VERY nice however, they are a little pricey not gonna lie. it would be kinda odd using some 500 dollar throttle bodies on a 30 dollar set of intakes and injectors lol.

On the plastic discussion... All i know is im gonna try out some form of nylon. and a phenolic spacer. I started digging into the nylon filiment research but i put it on the backburner. but now that im done building my nylon printer, its probably time for me to make a choice.

the blend part mentioned is very interesting tho. bringing out the best of both worlds. ill report back with some more ideas here soon on which nylon i think would work. i dont want these thing to crack over time which is my largest concern. so maybe find something really stiff to keep vibration from causing sway or find something with good twist properties?

thanks

you could probably just make one thats direct injected.....that way the intake is just a air funnel eye would think that wood be kinda eazy putting the injectors where the 2nd spark plugs locations are machined. of coarse a piston made for it would be nice too...and Im sore there are some out there that wouldent be too hard to make work. hell my 2.4 is only 88mm bore.I think the gm 2.0 direct enjected turbo is84, 85 or 86mm eye kaint remember at the moment. lotsa that stuff on flebay.I thought about putting the DI head on my 2.4( witch came along 3 years lator on the engine) more power more tq better millage, and the cr gets bumped from 10.4 to 11.somethen.( that would be a piston change too I think. DI works great for higher crs'.

OF course DI is better. My daily is a DI. But thats not the kinda of tech you invest into a 4 O well actually, if I had the tools I would do it but you'd have to weld in a boss for the injector. And probably cut some fins. And modify tin. And weld in a bracket to hold the injector down really good(because cylinders pressure is a new force acting on it).

DI is better, but not for this project.

good answer

[mark tucker]

not sure what boss needs welded....but if your going to the trubble of putting injection on it and want somethen different...and not have to worry about any reversion issues in non exzistant IR port....eye wood go DI. but since your not...you could also use 2 directional injectors in your intakes...I think

[mark tucker]

hmm Ill bet you could make some nice flowing turbo ends too!!

[Dauz]

Yeah, Jenvey is not cheap for sure..

if your woried ablut tall and skiney....add some ribs. BBQ sauce is optional.

Just curious why you chose to put the tab for the fuel rail under the tab on the manifold as opposed to having it on top ?

Thanks for the answer. Seems factory and aftermarket all bolt on top. Doesn't mean you have to be like all the other sheep. I'm definitely not one to follow. Seems all my stuff is one off

Anyway....I cut a stock dual port head in half once to check the aim of my injectors when I was building a CIS injection set up years ago. Maybe CAD up a head for those intakes and then you can see where the fuel will spray ? Back of the valve or the wall or......

Hmm. I do have a rotted 40hp head i could cut in half. It will be a little difficult it being a sp but doable. Thanks for the idea!

Well I printed my first test piece in standard nylon filament. Overall, it turned out pretty good for the first run. The supports really messed up the injector boss and fuel rail tab. So imma have to fix the support settings. But with a little sanding you won't even be able to tell these are printed.

And holy baby Jesus. These intakes are STRONG!

Nylon can be a nightmare to print. Do you have an enclosed printer? I highly recommend using Cura to do tree supports, they snap off and leave no trace behind.
