engine mods to a 2.8

[JMRQuattro]

what can you do as far as performance mods to a 2.8?? Does it work the same for the B5's as it does for the B6 and the 3.0 where there's basically no engine mods unless you get the 1.8t?

[tonelee1316]

pretty much. use the search button you will find all your answers there

[JMRQuattro]

you know i tried search actually and nothing came up. I searched for 2.8 mods, engine mods for 2.8, and a couple other different ways.

[D.C. Designs]

Well milltek has an exhaust for the 2.8.

[h4robkr123]

Basically theres exhaust, intakes, and the PES supercharger. And as far as i know that's it.

[Flash]

There's definitely some performance threads out there, I guess it's just been a while.

As other have said, there's intakes, exhaust and PES supercharger. The supercharger is the only major gain, but at about 4500-5000 new it's hard to justify the 90hp and the decimated gas mileage.

There's a few chips out there, but gains are marginal... claimed 10 hp. The problem with all this is I don't ever recall hearing of anyone dynoing their 2.8 with any of the minor mods, like chips, exhaust or intakes. Assume the gains are low.

I can report from personal experience that I definitely get better mileage from using a k&n drop in filter! At least 2-3+ MPG.

As far as I know, there are no performance cams out there for the 2.8. I think at one point also, someone made headers, but apparently the gains were minimal... but that could have been poor design or simply because the 2.8 30v engine is cam-phasing not switching... either way you had to take the engine out to install and for over 1000.00, not too many and not anyone I know ever took the plunge.

With the price of S4s, there isn't exactly a big market to heavily modifiy a 2.8.There's a guy with a remote turbo setup on his 2.8 and he's on cardomain and has vids on youtube. Again though, you've got to ask yourself how much time and money you want to put into this. Most people take it the wrong way when people say forget modding the 2.8, but really its just to save you from ice-skating uphill.

^^^true...but there are other mods as well like Supersprint Headers, RS4 LWFW/clutch, RS4 cams, Stasis cntr-diff-chng, Underdrive pulley and top pulley, RS4 motor mnts, APR snub mnt, 2Bennett oil cooler, 3.0 King built 2.8bottom end, i make cat-less Dp's for the 2.8, 3.0, 4.2 motors. IMO if you want power without a s/c the Dp's/catless is your best option. most people around the audizine don't play with the 2.8, 3.0 so your not gonna get much attention from anybody or find a shop that is even interested in the 2.8, 3.0. hope this helps.

[le91688]

There are gains with each mod... its just like every other car... mods are out there but you gotta find em.

1.8ts just think theyre so cool because they run 28 psi on a tiny ass turbo

[le91688]

im intrigued about this catless DP... do we even have a downpipe?

[TMorris]

There is a HUGE thread on 2.8 performance. Try and search that and if you cant find it, let me know ill look for it

Utilizing an MSD Launch Control device enables a driver to find the best launch rpm for his/her Mustang, and allows the driver to be consistent by leaving at the same rpm every time. Street cars benefit from a two-step because most of the time the car doesn't have a dedicated drag-race suspension

why not drop some money and boost it using s4 parts...or even better twin 25s like guru-just build the block

If you're going to go through that trouble, you're better off selling it and buying an S4.

And you can find used PES G1 and G2 Superchargers every now and then for $2000-$2500 here and on other forums. I'm actually been browsing for one myself.

Nitrous is always an option as well. I know there are a few people out there with it on their cars, and at one time I was considering it, however I think I'd rather SC it.

To be completely honest, I am considering selling my B5, and buying a G35 and SC'ing it. My buddy has a SC'd 350Z and it is crazy fun to drive, I just like the look of the G35 more.

I love my Audi, but I dunno if I'd buy another, the thing nickel and dimes me to death it seems.

His block is not built. He has a COMPLETE S4 swap with forged rods. However if you want to go that route you can buy the s4 motor and mate it with the 2.8 trans wich has to me has better gearing than thie 6 speed. this is not an walk in the park swap but there are those who have done it(my 2.7 is sitting on a pallet, while i finish my 1.8t avant car.) the swap will give you more options in the long run, but trust me the sc is a blast. I will be selling my sc when i start on that car. An s4 motor and harness can be had for 2k or less

[le91688]

sigma, what kind of SC will you be selling?

Where can you pick up a 2.7 for a decent price?

[Sigma 3]

I have a g2. I would check local salvage yards. I picked one up with only 20k on it. lets just say that my ps3 cost more than than what I paid for the motor The valves where bent but i didnt care because Im going to use my 2.8 heads anyway.

[A4 Effort]

Yes, yes, please tell us more about the cat-less dp's

[Sigma 3]

I dont think a catless dp will do much accept move your power band up, cost you low end torque, and make your car louder. But I havent done it so I dont know.

[anmagro]

+1 on the DP

I would kill for an S4 engine, like, actually kill.

Are you sure you can put 2.8 Heads on a 2.7 block?

Sigma 3 ... do you have an idea of when you will be selling the G2? I need one.

[Das General]

Guru uses twin 28's and he started off with a 2.7 s4 motor. A 2.8 a4 motor is different, even more so if it is a 12v.

I have built 2.8 heads on my 2.7, I reused the 2.7 intake manifold though.

[Sigma 3]

ANMARGO i dont know for sure, but i will post on here.

Derek what are you doing slumming in here?

[Das General]

Just spreadin the gospel. = )

[3.0 King]

Yes, yes, please tell us more about the cat-less dp's

what do you want to know? the 2.8 has two Dp's/cats. i make dp's/without cats thats it. check my gallery for a set of dp's for Supersprint headers that i made for my car. i'v built seven 3.0 motors, four of my own and three for guys all on this site so anybody can check my work. also two 2.8's and now i'm doing two 4.2's at the same time so if anybody has a specific question lets hear it. did anybody bother to read the list options that i wrote^^^earlier.

[anmagro]

Sigma3....thanks for the info on the G2, but lol, its anmagro not anmargo. Magro is my Last name. Couldent help but correct.

3.0King - i would like more info on your background and services. do you own a shop? Business? How much would a built 2.8L 30V cost? And to what extent is it built? Do you have links to the members that use your built 2.8L Block? i am guessing they are supercharged.

[black00A4]

So what would a set of cat-less DP's cost for the 2.8?

[le91688]

how do we have downpipes when we are Non turbo?
U mean headers?

[audiornothin]

Dude check out spectre performance and build yourself an air intake it works great! I built mine on my 2.8

[3.0 King]

how do we have downpipes when we are Non turbo?
U mean headers?

...lol are you being seriouse with this question?

[3.0 King]

So what would a set of cat-less DP's cost for the 2.8?

$900

Craigo, Mavrick, Jklugi, are the three guyz in the B6 forum with built 3liters.
One local girl (my home town) with a B5S4 with a built 2.8 running stg-3 home brew kit. Another local 2.8/G2.

A new built 2.8 short block will run you $5400+shipping.

I don't do this for a living it's a hobbie. I work out of a friends shop with a machine shop on site and welders, pretty much anything i need to get the job done is on site and my mentor is Richard Hawse owner of European Auto Care in Pasadena MD. you may have heard of him. Also known as the Donut King because of his 1992 Rear-wheel drive VW Corado. There is a whole write up in Eurotuner check it out. I also had my car featured in European Car check it out.

[anmagro]

3.0King, thanks for the info. Should we just search for 3.0 King then? lol or is there a name.

How many psi is the built SC 2.8L running, do u know how much power hes making? Im very intrested in your blocks, im looking into something like this before i supercharge.

[JMRQuattro]

Basically from the sound of it getting a B5 S4 is a better idea. Especially seeing as how the S4 isn't all that much more expensive. I think the extra cost of the S4 would pretty much be cheaper than all these expensive mods you guys have listed so far, and correct me if i'm wrong, still better performance. Because the gains i'm reading definitely don't sound worth the price. Why don't they ever make more mods for the bigger engines? The smaller engines always get the stuff. It's like my 2.8 passat, i can't do shit to it. The jetta gets all the mods. There's hardly even anything to mod the exterior of that thing either. It really sucks.

[Sigma 3]

Are you going to be doing all the work on the s4? have you priced the mods for the s4? I would not say its cheaper. Goodluck
