So i have 5-6 months of winter ahead of me, so me and friends wanted a little project, im gonna store my A4 for the winter and use my truck, The a4 is quattro, but dropped, so not good in snow.
Anyway, the questions.
1) does anyone know if 96 S4 manifolds will bolt on to the 2.8, i would imagine they are pretty similar. If not, i will have access to a machine shop in about 1 month and will be able to machine out some flanges.
2) Does anyone know a chip that would work for this, i see eip tuning has a VR6 chip for 96 jetta 12v turbo kit, and i know the engines are very similar, but dont know if they would work.
Any suggestions on chip, or fuel management would be helpfull.
3)Has anyone every tried this before? What turbos would you recommend, twin or a large single? Obviously the S4 turbos would work.
4) Any suggestions you have would be helpfull, i fully intend to go thru with this project. I plan to have 2 hood scopes, one on left, one on right for intercoolers depending on size.
and want to perform a MAJOR performance mod to it? Maybe you should do some searching in this forum and the 12V forum. I know of 1 or 2 people to ever put a turbo on a 12V. You're going to spend thousands and thousands of dollars. And the VR6 is not like the 12V, they arent even mounted the same.
hood scoops, with those you dont need a turbocharger
a turbo 12v has been done before, but not on the AFC, it was done on an AAH 12v.
the AAN in the 96 s4 is an inline 5 turbo not a v6 turbo like the APB or BEL. no inline 5 parts are going to work for the V6.
you would need a custom exhaust manifold
you would need custom plumbing.
engine management starts at $2K plus tuning time on a dyno which runs $140 an hour... figure several hours to get a decent program hashed out and running. No there are no ways around this... again there is NO other way to do this. If you dont like that answer search and find out why it is true... I assure you EIP makes nothing for the Hitachi ecu in your A4.
I once turbocharged my Bichon Frise... it was fawkin awesome!
I would guess you can use any built for Audi turbo you want considering its a custom project. I would go with the K04. The exhaust manifold will definitely be a one off piece but the turbo/downpipe/exhaust could all be 1.8T stuff. Im guessing either stand alone fuel management or having a one off development for your 2.8 ECU fuel and air. I really dont know how it all works, as far as boost control and what actually controls it. I know Level 10 does custom programing but my mechanic had mentioned a guy that develops custom programs for audis. Next time I talk to him if I remember ill let you know.
Sounds like a huge and costly project. I wouldnt know where to begin, I just read magazines.
Why not a K04??? Too much heat from the extra liter?
like i said I just read magazines, one day ill mod a car myself...But couldnt you fabricate a common header for all six cylinders to exhaust to a turbo and why not a single K04, is it simply too much for it to handle? Oh, about custom plumbing, now that I think of it no way you could use 1.8 stuff, no way in telling where the turbo would wind up in the engine bay. Hope you can get Jessie James to weld up some pipes baby...seems like alot of work and alot of money to spend for some exclusivity...but I understand.
Ah, but i know plenty about my engine, it's the other 2 that i was wondering about, and now i know. don't be so quick to assume that you are smarter then everyone. It's true i didnt research the other engines yet, i just started, i wanted to get the post out and get ideas.
the level of complexity involved in adding a turbocharger to an audi is VERY high... Jessie would weld it to the hood of the car and call it done... However that doesnt actually do anything other than increase aerodynamic drag and look incredibly stupid as a hood orniment.
You are obviously not ready to undertake this project. If you want somebody to do it for you then just save up $5,000-10,000 and go have it done... mind you it will take a shop several weeks to months to make this happen as they have other projects going that are probably more important than yours.
Definitelty a feat to overcome will be trying to stuff and keep cool a large turbo in this engine bay...It will all come down to having the right tools, it always does.
Your gonna need a huge intercooler with a mister like the EVO to keep things cool. Perhaps even some sort of ram air scoop that channels more air to pass over the turbine itself...
Once you weld all that stuff together what else would you need to do? The chip will basically adjust the fuel/air ratio right?
oooo you can have a BOV instead of a diverter!!!!
that alone may be worth it!!!
I dont know what else has to be done but since were discussing it id like to be educated if you dont mind.
1.explain wastegate and where it lies in the system
2.Actuator Rod / Diaphram, what control is this?
3. Boost Timer or Controller or turbo timer?
I know one keeps the engine running after we remove the key to help oil cooled turbos move thier heat. The other can adjust boost from inside the car electronically, is there a manual boost conroller? I seem to be confused.
All in all the system doesnt seem that complex. Ive never been under the hood of a car so im definitley missing out on some stuff.
why is he making it seem so difficult to accomplish?
or why is he making it hard for you to ask questions? i don't know about the second question, but the first one (accomplishing the task) is going to be pretty fricken hard to do. Designing good manifolds is pretty hard to do WITHOUT a space contrstraint. Considering our engine bay is plenty tight with just a 1.8T, trying to fit twin turbos in the engine bay with a v6 is going to be tough. It's going to take a lot of work and tight radius bends to get that accomplished. In all honesty, Quattrofrog is making it seem so difficult because it is. He's not speaking out of his ****
Please dont assume im stupid, and foolish, this is not the case. Im not a 16 year old that decided to try something, i have looked at the "space constraints", have access to a supplied shop, and have A friend that is a mechanic helping me, plus other well knowledge friends that know their stuff. 2 mechanical engineers, and i myself am an electrical engineer.
I didn't post here to be flamed by you guys, i wanted suggestions.
Please dont tell me "you cant do it cause you suck at welding / mechanics / lack in knowledge.
This project is very doable, and im trying to find a make it cost effective also.
So close your mouth if you have nothing helpfull to say.
Re: hood scoops, with those you dont need a turbocharger
The manifolds and plumbing wont be a problem so to speak. I will be able to get the manifold custom machined, and since its my friend there is no labor charge. He is also knowlegded is plumbing having an array of tools for pretty much any job.
i know its going to be work, but fun and worth it
You're the one who said you've never been under the hood of a car. Therefore, you've COMPLETELY disqualified yourself from assessing the difficulty of such a project. In order to do stuff right, you can't just "weld all that stuff together." To do a job right, you need to have a fair amount of engineering knowledge. There's a reason that there are only a handful of companies who make quality programming for a particular car. Efficiently tuning a car requires lots of equipment, time, and most importantly, SKILL AND EXPERIENCE.
Actually there is a turbo AFC 12V, you might want to search for AudiBoy, he can provide you with the info you need to do it, Most of his parts are custom machined by him. Also you will most definately have to run a Stand Alone system as there is no way you will be able to find a chip or reprogramming of the MMS-411 I gurantee that. Audiboy did something to fool the ecu, it was a temp fix not sure what it was you might wanna ask him about that, there's pics of his setup also.
