So i drive an 97 A4 2.8q
and after seeing how a guy on audi world did his rear mount turbo setup
i have decided to venture into it and start doing mine.
I have a T3/T4 .50 A/R in the mail.
so i will post pics as i go in on this monster but
what i need is all the help and advice anybody who has done this before or knows alot about turbos.
Im use to building wierd ass cars with wierd mods (twin engine honda civic, Twin trubo mr2 engined Fiat 600) and now decided to mod the daily driver.

good luck mikey...i don't recall anyone doing a turbo replacing the exhaust on an A4 before. your from ETK correct?

i think the challenge will be the piping/charge pipes....oil lines...s/w prolly CTAPP S/W. not sure where the charge pipes are gonna tuck in under the audi. have you talked with any tuner on the sw/fueling your going to be using?

money limits here.
the t3/t4 was all i could do for now.
maybe ill move onto a big garret in the future when i sell my honda.
then ill have 14k to spend

the only way i would think this project would be a good idea, or even work to it's full potential, is if money wasn't a limiting factor..

this is a big project and will take a big budget to do right

mikeyvuitton
03-27-2007, 10:19 PM
well i meant i have enough money to make it run off the t3/4 not like a Garret. im selling of my 1st place HIN winning honda then ill have the rest of the cash to fund this project. I just ordered the Rs4 kit this weekend and my VIS hood.

STS Turbo?

BranCKY3
03-28-2007, 09:15 AM
STSturbo has this setup for a lot of cars. As long as you tuck everything underneath really nice, I don't see how you'll have any problems compared to a regular turbo setup. It's working great for other cars I don't see why it wouldn't for a 2.8.

new question..
What chip am i going to have to use?

bronz
03-28-2007, 09:23 AM
and i say make it double tips so looks nicer use Y-form from turbo and get nice short tips

You don't have to put the turbo exactly where the rear muffler goes... You can put it in the middle of the car or anywhere you have space. There's still room for a rear muffler if you put the turbo in the middle, and make it look nice and sleeper.

yea i dont think your going to be able to run a "chip" as i no tuners are going to have one available, you are going to have to go stand alone

gotaudi
03-28-2007, 10:23 AM
What I would do is contact PES and see if their supercharger chip would work with this application, that is where i would start. Hey who knows maybe he can have it dyno tuned and use the PES chip as a base map... It might work... How much boost are you going to be running???

on a more realistic note

What you should do is sell your honda and audi 2.8 A4 and buy a 99.5 1.8T B5 A4 for around $9000 and put $7000 into it for a pretty fast ride..

Good luck anyway

gotaudi

your theory is correct with a larger displacement but one problem with your idea is availability of: Parts, Help (If you ask a question you will get limited responses due to the fact no one knows your setup)

The 1.8T motor is a very potent engine a lot of HP can be made with very low displacement some of the 1.8T are faster than the S4 engine... One thing you do have going for you is you can run one big turbo and still spool it rather quickly. I am going to say this: If you have a lot of money, time and know a lot about how a turbo engine works then go for it, more power to you... If you do it right it should be a very fast car

Good luck

you should have gotten a bigger t3, a larger t3 wouldnt cost much more, you dont necessarily need to buy a garrett.

gotaudi
03-28-2007, 01:56 PM
The turbo that he got will give his a pretty quick spool, this is why I though he could maybe use the PES supercharger map...

audispeed
03-28-2007, 02:34 PM
well if the 97 is a 12 valve, which i am pretty sure that it is, he better like stand alone engine management since nobody will chip tune that for him and PES s/w wont work

dozentrio
03-28-2007, 02:50 PM
cool idea. Too bad there's not a bit more room under there to place the turbo, piping and stuff.

Sell the 2.8 and Honda, buy an S4 [:D]

jbrentd
03-28-2007, 02:55 PM
iirc, that piping was only temporary for testing and he was running somewhere around 5-6 psi of boost and letting the stock software account for it.

ActiveMonkey
03-28-2007, 02:55 PM
or not pay twice the insurance, and keep the 2.8

Lets see this honda...

Eccentric. I thought there was some guy on the internet w/ turbo 2.8 beating s4's??? I'll look for it. Looks like euro plate will say hung lo. There's no room for that under an a4 quattro. Try it on the pacifica.

also considered truboing a 2.0 jetta......

2.0 jetta don't get the same power output...my brother had a 2.0. you won't crack 200whp with a turbo kit unless you go crazy. not much return on the 2.0...we did spray instead with bolt ons.

that 2.8 turbo....that turbo hangs low....too lowfor me. the STS systems tuck up nice. that thing hangs low. like scrapping low.

You should develop your kit more. I know people would pay good money for a rear mount turbo setup. Try metering fuel with a piggyback controller and put the turbo where the stock resonator is. I'd be extremely happy with a kit that boosts 5-7 psi reliably.

How about doing a twin engine setup on the audi? like you did with the civic...

not to be rude or anything, but from the posts you have made, it seems as though you dont quite have the knowledge, or resources, to make a remote turbo system work for the 12v motor.

i would say your best bet is to buy a 1.8t.

people have also said me and my father couldnt put two engines in a honda.

Im just waiting for the turbo to get here then plan from that

A big mistake waiting to happen. You could have actually bought a decent 1.8t for the money you're about to waste on this idea.

do it, do it right, tuck it up inside the frame. tune the thing right. it is very cool idea, you can then take off the system to sell it separate when the time comes.

you should build the engine with some rods and lower compression pistons so you can bump up the boost

2 ecus.
to run fwd shut off the rear engine to run rwd dont turn the front one on.
or turn them both on and have fun..

or for the real fun put the front engine in forward and rear engine in reverse and do donuts in the same spot.

This is such a bad idea...sad part is someone always brings it up and tries to sell the idea to unsuspecting individuals.
Remote turbo's work great on big V8 trucks that are high off the ground and have room to hide a turbocharger neetly.Will it make power on an Audi 2.8 V6?Yes it will...any forced induction system will.
Will it last?No it will not...there is not enough room under the rear to even mount a diff cooler let alone a turbocharger.
Your best bet with the 2.8 V6 engine is to throw it away and swap in a 12V VR6.
