16v's what you think?

[dspl1236]

this is my 3.6 32v v8...16v's seem the best place for me....

started this idea about a month ago.....






v8 gasket on v8


16v lower bolt hole


v8 gasket on 16v mani


16v mani on v8






3x '08 '09 Kawasaki 1400zg throttle bodies

v3



v4 - final unless machinist says otherwise....just called.. he wants to change it already












off to the machine shop

Cool project. Looked like some kind of monster with the two 16v manifolds bolted on. Still, I think this is better suited for the V8 forum, regardless of displacement.

dueling 16v mani would have been sweet....just real awkward intake setup. thought about the rocco intake, but the plenums are different sizes

could be....but those guys are all 40v's....just not the same as 32v. come on ...i dont think its fair for me to say that all dohc i4's should post together regardless of displacement. but you do have separate 16v and 20v forums...

i felt it better suited here since the v8 is well a pair of 16v's with less power.... you can bolt a v8 head in place of a 16v head...so its like almost one in the same to me

[Smiff]

Take lots of pictures and make it pertinent to 16v engines and you won't have any problems here.

So you think that intake plenum would be useful for a 16v engine trying to run ITBs?

So you think that intake plenum would be useful for a 16v engine trying to run ITBs?

i think so. i plan on drilling and tapping my heads to match the 16v bolt pattern. basically been using the 16v ports as my template. direct bolt on itb without the proprietary throttle setup like kms. i plan on making a version 5 that is shorter and even cheaper to make. 6061 tool plate. shooting to have a rough one made by xmas and then a few finished sets made by end of jan. being made for the 43mm kaw 1400gtr throttles over the 40mm 1400zg's i have. gives me a reason to upgrade after all this is running. i just was not trying to spend $800+ per head just on itb's...so this is my solution.

each like new itb set i bought for $49 came with bosch 440 12 hole injectors, tps, Mitsubishi map sensor, and some kind of motorized isv.

I am using a DTA P8Pro standalone i picked up from a local 2.2 16vt 4mo rabbit

[antichristonwheels]

I touch "myself"

[MK1 Rabbit GTI]

i like the twin 16v intakes. looks mean. could always get a euro 50mm intake and 50mm scirocco intake

[ejg3855]

Where are people sourcing ITB's these days?

[MK1 Rabbit GTI]

ebay is your best bet

i like this..if my itb fails....new fall back

Where are people sourcing ITB's these days?

i did ebay, then found that the ebay store was like 45min drive...so i ebay'd same day

[dspl1236]

last renders of v4 to get an idea what i need to change. off to garage!

v4 is just too close. nowhere to put velocity stacks! v5 is already in the works

[Glegor]

now it needs SOME turbos..

[V-TEC this!!!]

There already is a turbo!!

[Sallad]

Holy crap bud, thats pretty cool!

I like the regular 16v intakes opposed to the ITB setup. Looks a lot more aggressive... but them again, when all those carbs are bolted up, it's look cool. Especially if they all shared a common air filter. Like a long oval one or something. lol

[Smiff]

User v-dubin@120 had a custom carb mani on his motor, should work similarly for itbs. Do this on both sides for 8 kinds of awesomeness:

[dspl1236]

this is the fixed version v4.2. intake face angels and block width are now correct. still have not made a shorter/easier to machine v5 flange yet....






i am already freakin out about tuning from scratch standalone on a fresh itb setup.....let the boost come anther day....but it looks just too easy...must stop







oh ya..thank you guys for the fsi coilpack info

[dspl1236]

quick project overview

1991 Coupe Quattro

just bought w/blown hg and flatbed delivery. mid sept 2010


pulled the n/a i5 20v out


prior to standalone and itb




few times ever fully been assembled and sitting on her own


november 2011....then it went downhill


ok back to your regular programming

[psychobandito]

what are you gonna do for velocity stacks?

[dspl1236]

what are you gonna do for velocity stacks?

well looking at KMS...but no matter how i do it ill have to do some side shaving to fit

[weeblebiker]

you may find aproaching the mani this way alot easier it was for me and my machinist freinds, the oval to round transitions are the stopper for time needed to program and fixture.

this mani puts the itbs 2 1/8" from the head
could get it down to 1 1/2" ish if you cover the cis ports and use a plate flange instead of the casting

AND i THINK YOUR IN THE RIGHT FORUM,,, IT'S ALL ABOUT THE TOP END OF THE MOTOR









this is the thread

[weeblebiker]

you have not already, you absolutely have to figure out and accomodate your dual throttle cable issue and vac connection to each itb so you can balance the idle on all 8 throttles ( that will be a fun job )

off the top of my head: bmx freestyle brake rotor cable split type set up
or run one bank upside down to get the trottle pull on the same side and run the cable pull in series

I found the mani, design wise, one of the easier parts, the harder part of the project was clearancing and connecting.

[Glegor]

any progress? or did this project fall by the wayside?

[86Franklin]

I say itbs at the end of the 16v manifolds. Or just go all out and do this

[Smiff]

^. So cool. I stare and try to comprehend....

[dspl1236]

negative still going forward.

had to acquire new technology for my vision.

[weeblebiker]

all your initial pics links are broke.

what material is that for the head to itb piece? looks like Delrin (I work with polymers)

your injector placement will cause issues going into and off throttle. your going to be pooling fuel on the manifold walls. I tried tuning with my injectors in the itb position and just could not tune out the lean and rich conditions for daily driving. for track or strip it won't be too much of an issue.

So I'm now running injectors in both positions

[dspl1236]

these test pieces are PLA and final will be made out of nylon.

i saw your build thread before. ya this is will be my toy. hmm on the injectors..i see what you are saying. looks like you have stock 1.8t injectors with some 36lb'rs. i have 12 hole bosch 440's currently.

ill look into this...or even shorten my adapters


inspiration..i know its 40v and not a 32v..but still awesome


ill see what i can do about fixing all those photo links

[weeblebiker]

may I suggest a higher temp material? unfilled nylon may get soft and deform at head temps causing leaks. if cost not an issue, glass filled PEEK would make a machine it and forget it piece.

I had 50# delphi 6 hole injectors in the itb position (E85).

yes 1.8T long nose injectors in the oe position to get the injector as close to the same position as the cis injector the head was designed for and the 36# gsxr injectors in the itb position.

also the back side of the itbs can be opened to a 1.75" id with a 10* taper end mill. makes doing the tib to head transition a bit smoother. I'll see if I got picks, if not I may be pulling the itbs off soon so I can tak a pic then

[weeblebiker]

at the very least, you will have designed a piece that can be sold to the 16v guys

[dspl1236]

pics would be sweet. i can do abs too..pm'd

[20v_boost]

Well since you'll be fabricating anyway, put down the ITBs and take some inspiration from this sweet LS7 manifold.

[dspl1236]

^ thats a sweet boost setup.

just bought a b5 a4 with a broke 1.8t tb...ill be on that all day
