hey guys/gals, ive searched and im wondering if anyone has turbo'd their 2.8 a4. like i said, i searched and couldnt find anything. Any kits or anything out there? Thanks

 

Yea.... no. Most people with the 2.8 go with supercharger. Which you can find here. Not worth the turboing of that car when the supercharger is available.

 

You'd spend $10,000-$15,000 to do it right... Just Supercharge it, it's much cheaper.

 

yup someone did it already and thats what it costed him

 

eip has kits for the R32, they start out at ~8k in hardware alone.

 

Well this is the way I figure it, since not too many companies build parts for Audis in this sense, it's going to be about 3 times more expensive to have the parts fabricated. If it were a Honda, you can be boosting for as little as $300. But still, I have friends that have spent $20,000 on their powertrain alone. So it's all a matter of you well you want to do it.

For a 2.8Liter V6 in an A4... Figure this:

Golden Eagle Bottom End: $7,500 or so. They'll have to develope a sleeve design, Arias/JE/CP will have to custom produce proper pistons, wrist pins and rings, Golden Eagle would have to custom design and produce proper rods, they would also have to design and produce a crankshaft. The block would have to go through quite a bit to get it able to accept any kind of power. Then you'll need strengthened hardware... No company makes these. ARP would have to custom design a set.

RLZ Heads: $5,000-$6,000 or so per head. They'd do their thing with the port and polish work, Supertech or a company of the sort would have to design and produce titanium valves/springs/retainers, not to mention you'll have to get a custom set of Camshafts designed and produce, Crower does great custom work, at a nice price.

Full-Race Turbocharger System: They do great custom Turbocharger kits for anywhere from $4,500 on up to $10,000+. Keep that in mind.

Full Aeromotive Fuel System: Figure you'll need an Aeromotive FP/FF/FPR/-6an SS Lines, a custom fuel rail, and you'll probably need some nice sized injectors from RC Engineering, and now you'll probably need one Hell of a Stand-Alone EMS... The 036 System should work, it's only $1,400 or so, so that's the least of your worries right? Then you'll have to find someone to tune it, P1 or Church Automotive could do it... Figure about 12 hours worth of tuning, at about $150 per hour.

So after all of that work, you'd maybe be able to squeeze 500whp-700whp. But keep in mind, after about 500whp, it's no longer efficient, and the thing will need to be tuned and twirked constantly just to keep it running. So in the end, does this make any sense?

Then do you think your stock Suspension and Brakes be able to handle this new power? Nope...

Do I need to go on?

This would be a very pointless project, unless you have the money/time/skill and you're looking to prove something.

Buy an S4.

 

where do i sign up!!!!

 

Tell you what, you front me $50,000 or so, and I'll take care of everything.

 

Who says he's lookng for that much power?

On a conservative budget minded build 300 hp shouldn't be that hard to conquer for under 6k.

A few easily accessible used parts can be used to make it a lot cheaper.

A t3/T4 50/63 is plenty sufficient for 300 hp.


Let's make an ec\xagerated price list.

034EFI standalone- Lets make it a hefty round about price of $1800
Turbo, t3/t4 50/63 - $700
Suitable injectors (you do the math on exact size, you could probably use [6] 1.8T injectors) $2-300
El Cheapo yet effective IC - $300
Random Piping - $500 ($2-300 if you canweld by yourself)
Custom manifold - $500
Custom exhaust - $3-400

Misc parts since I don't feel like listing everything - $1500

That's $5300 and can be done a lot cheaper.

Then again, I'm kinda drunk, so I'm not completely in the right state ofmind and won't feel like editin my post tomorrow.

 

I guess that would work...

Oh and I forgot another thing... The stock intake manifold won't suffice. Better get a custom one made, I know TWM researchs and developes custom ITB Plenums for... Uhhhhh, about $4,500.
