Supercharging - B5 2.8 30V PES G2 - input please

[QuattroS.Africa]

Hello B5ers.

I have decided to take the plunge and supercharge my old girl. I know this probably was discussed at length but my circumstances are somewhat different:

1) My car has 481300 km on it ( about 301 000 miles )

2) I live in South Africa hence the ECU tune won't be accurate- variables like altitude and fuel quality will render the PES tuned ECU useless

3) I have to factor in shipping and taxes


I have seen some real horror stories regarding the G3 on the 3.0 B6 engine, but from what I've been reading there havent been 2.8 engines blowing with the G2.
Correct me if i'm wrong.


YES for those of you who are familiar, I do own the super rare RS2 but I really want to keep that car stock. It has just over 60 000 miles on it - for a 1995 car thats incredible.
So to satisfy this craving for a tuned Avant i'm turning to my B5.


Any constructive input will be greatly appreciated

step back.

did you just say, you want to supercharge a motor with 481 300 km on it?

Just give me the RS2.

Shut up and take my money.

301 on the clock means your gonna have some wear. thats the highest mileage 30v i've heard of. since you've kept the rs2 to 60k, im assuming you're the kind of guy to keep your cars in good condition. regular oil changes and proper maintenance goes a long ways. id do a compression test, and if your numbers are acceptable, i say go for it.

as for the ecu, i'm sure theres something that can be done about that. all the ecu's are very, very close between comparable models across continents. (97 1.8t north american ecu = 97 1.8t european ecu) i'd confirm these facts with others that know more, but i'd be willing to bet a few dollars the tune is writable on your ecu. orrrrr, you could just run a north american ecu. one thing i'm not sure about is immobilizer's. north american b5's dont have them. i know some overseas b5's got them, but not sure on the years/models/sub models.

if you really want to satisfy your craving for tuning, sell the 2.8 and buy 1.8t if you want to keep it in the b5 family. or of course a b5 s4.

i also have over 300,000 on my 30v

I am running a G2 on a 200,000 mile engine for a few years now.

The RC injectors that come with it are outdated, I upgraded to some Bosch injectors.

I think if your car has good comp on all cylinders you will be fine.

[QuattroS.Africa]

Thanks for the responses guys.

The B5 S4 and RS4 never came to my country. So the highest specced B5 is the one I own.
1.8T only came in FWD so thats out.
And besides, I cant drive a four cylinder!

[Seerlah]

The G2 was fine for the B5 A4 chassis. It is the PES kits after that which were crappy (like, blow up your engine crappy). Even the PES tune ran decent on the B5. The blower was never the issue. It was the tune PES provided. So if you are getting your own tune, you'll be just fine. The PES tune for the B5 was actually pretty decent, since many ran it with no issue.

So let me get straight into this then- PES wants $4k for the G2.

Dude on scaudi.com wants 2k. But he's got a slight crack on the OUTER wall edge of the manifold which has been repaired with epoxy but "isnt a strained part of the manifold" ie no pressure goes near it as it's on the outside.

The kit looks complete.

But I am shit scared to bring it in all the way from the US to find that its a lemon or that I've blown my engine.



That ought to put things onto perspective

Help me make the decision guys.
You're all I have on this issue right now.

[Cgoon009]

what if...

you turbo charged it, buy a good turbo, and do the piping yourself? I think you could put together a good system that way. May be less then 2000? Def less then 4k

You could talk to Max over at 034, they did some testing

Who is going to tune that though?

Going to be tough to tune a ECU not designed for forced induction(turbo running anymore than wastegate pressure).

Maybe you could use a S4 ECU....

If he had a DBW car his tuning options are much more open. As it is, he's stuck with PES's file.

[Cgoon009]

^ thats what I was thinking, or stand alone? I know that can get expensive

[A1 A2 German]

Currently have the PES G2.

The RC Injectors, as kinda touched on before about being out dated, are not proper for VAG cars due to their spray pattern (perfect for Fords).

Genisis or like will be going in to replace the RC's. If any one has good dbw software recommendations post up.

I suppercharged (with a G2) my B5.5 Passat GLX 4Motion 2.8L V6... It was a nightmare. Theres a reason I sold that car for 1500 bucks when I was done with it.

[QuattroS.Africa]

Thanks once again for the responses.

Turbocharging is not an option- I honestly dont need the headache and was looking for a straightforward reliable REMOVABLE mod.
After seeing what ToXicxXx has to say, I am beginning to worry....

What problems were you having?

[ToXicXxX]

Almost anything that could go wrong did. My engine was at 215,000Km, and I honestly just think it wasn't able to handle any added boost. My favorite was picking bits of cam tensioner out of every nook and cranny of the block (it also seized my oil pump, which lead to more issues). I dunno if i had bad luck with the ATQ, but in a year of owning it, it was apart in my garage 4-5 months. If you want a boosted engine, get a 2.7 or a 1.8 :)

[Nollywood]

Personally, I would stay away from the G2 set-up.

My advice would be to go for a single turbo set-up, run a B5 S4 engine harness and ECU. A bit of work involved - you'll need to add EGT and MAP, but not too terrible to accomplish.

You guys are like that pushy family member at a resturant who was that food you don't want

"Oh come on, try it"
"No thank you"
"No, you'll like it"
"No..."
"No really, I promise!"

OP wants Supercharger.


Anyways, the G2 is far from ideal. Like everyone says, to sum it up, it's like it wasn't even designed for the B5. The injectors blow, the tune blows. If you can find a G1, it's a little different.

If you had a lower mileage car, I'd say maybe, ok, w/e. But IMO, such high mileage is recipe for disaster.

[QuattroS.Africa]

Keep it coming folks. I want to hear as much as possible

[AudiA4_20T]

Are guys tuning B5s themselves now like the B5 S4 crowd is? I can't imagine if you had the ability to log wideband/maf/boost someone on NefMoto couldn't make a decent tune for it

The mileage is definitely a concern, although many have said its all good because of how well maintained the car is.

My mechanic feels I have to rebuild the bottom end. I have a quote for like $1400 for that alone.
If I factor in the charger and the subsequent tuning, I may end up spending too much on the car.
So based on all of your input I am taking a decision NOT to supercharge

I really thought this would work.
But I'm pretty freaked out. Thanks for all your help guys.
This topic can be laid to rest.

I'll wait for my cousin to get bored of his 2.7TT allroad so we can Stage III it to the moon

[QuattroS.Africa]

To reward you for your help, I've updated the picture thread on my RS2.
Enjoy

[redline380]

if a rebuild is $1400, why not just htrow the charger on it and run it till it blows? at the same time, pick up a junkyard motor and rebuild it, then swap it in after it is done.

edit- you say you won't go 1.8t cause they were only available in fwd. why not replace the v6 with a 1.8 and tune that?

[ZimbutheMonkey]

Redline380, love the quote in your sig. Probably one of the best movie lines I've ever heard lol.

hand's down my favorite movie. i usually watch it every few months. there's so many awesome quotes. this is one of my favorite scenes. sad part is, i'm sure it isn't too far from the truth. oh, and little johnny depp is in it

I've been playing with vw/audi for 16yrs now. I have a vr6 turbo mk2 that has been with me for over a decade and has been through many variations along the way. The first setup I had was EIP fueling/chip (today is megasquirt 2 with a T04Z by Garrett). The kit consisted of a chip and fuel management unit. The chip seemed to have little done to it from a stock tune (confirmed ignition with vagcom) the injector size was stock for the engine and the increased fuel was from the fuel management unit. It provided sufficient fueling until ~17psi of boost on a t4 turbo. If I put forced induction on my b5 30v street car I would probably use the same FMU (Cartech brand) and limit boost to ~10-12psi and run a wideband to keep an eye on things.

[A1 A2 German]

Any know of over the counter tunes for the G2 system other then the PES?
