Audi A4 B6 1.9 130 quattro build.

[GuitarGuy]

So just writing this post as I'm planning the purchase of a 1.9 pd 6 speed quattro 130hp a4 in the next couple months.

The aim is to build it to around 300 hp and around 350-400 lb/ft whilst retaining most of the economy (somewhere around 40mpg average at least ideally but id settle for 30).

Im thinking the following will be required to get there:
Bigger turbo,
cold air intake,
3" turbo back exauhst,
front mount intercooler,
bigger injectors,
fuel pump,
clutch
and finally a remap

also plan to lower the car with some new fast road style shocks and dampers while still retaining ride comfort for the motorway and such. not crash so much as progressive I'm after, along with some thicker sway bars front and rear to reduce body roll.

Obviously with great power comes great requirement for solid stopping performance so maybe some 300+mm front disks with the callipers to match?

I'd like to do as much of this stuff as possible with bolt on parts but I know not all of it will be.

I also don't know if this would actually reach the target I'm going for.

also would this warrant a build guide as it would take months and months and months to get there?

Any tips warnings or recommendations regarding all this?

or for a lot less money you could buy an s4. mine gives 326 bhp an 550 nm of torque from its 2.7 bi turbo petrol engine. it revs beautifully round to 7k rpm and doesn't produce bucket loads of black smoke. it also sounds nice, being a petrol. if i spent another wedge of cash, probably about 1/4 of what your oil burner would need, i would have over 500 bhp. admitedly it won't do 40 mpg, but petrol is cheaper than diesel.

[GuitarGuy]

would an s4 do even remotely close to 40 mpg? and the difference is this is all incremental meaning i can do my upgrade and add the cost to the insurance as I do it as opposed to insuring an s4 as a 21 year old..... you don't buy a car in parts but adding parts to an already good car makes sense right?

this seems waaaaay off the mark http://www.autotrader.co.uk/classified/advert/201404023006897/sort/default/maximum-mileage/up_to_100000_miles/make/audi/advert-type/Classified/radius/1500/keywords/quattro/price-to/6500/quantity-of-doors/4/transmission/manual/model/s4/postcode/cv57qy/usedcars/onesearchad/used%2Cnearlynew%2Cnew/page/1?logcode=p

[zollaf]

an s4 is going to blow the bank for you insurance wise, but so is any smaller car with a heap of mods. my s4 is the earlier one, 1999, with the v6 turbo, the best one they did, and highly tuneable. the v8 is nice, but no turbos and harder to tune. i have no idea about insurance though as mine is on my traders policy.

[GuitarGuy]

I concur however if i do it incrementally it'll be alright. We're talking a couple years for mods by which time ill be 23 and have 5 years no claims. Shouldn't be too hard to swallow as ill have hopefully finished uni and gotten a job by then.

And aside from that I'm a diesel fanboy, i like my diesel power. Petrol is nice for cars like integras and rx7/8's motorbikes and other insane high revving beasts.

Diesel seems far more suited to daily driving in my opinion.

[zollaf]

diesel is good for doing high miles, nothing else. if you need to do 25k a year then a 55 mpg diesel is great.
if however you want a fun drive then you need petrol, preferably with turbo or 2.
incidentally, until you have driven an s4 you really have no idea. an rx7/8, integras and most motorbikes are mere toys for pootling about in. the bloke in the civic type r thought he had bought a quick car until the other night when he got out accelerated all the way to 70 by the old estate car . :) diesels are smoky old smelly things. don't get me wrong, they have their place and my 80 is fairly quick and economical and runs on veg oil, but petrol rules.

[GuitarGuy]

i did 26k miles last year and got 35mpg in my 1.4tdi 05 polo so yeah diesel efficient I'm yet to experience. but hopefully it'll be alright in an audi. I need it to be capable of cruising efficiently but want lots of raw power for many many many smiles :P

though i disagree that diesel isn't or cannot be fun. A friend owns a 500hp diesel e46 320d thats been fully built at ridiculous expense that is insane fun as driver or passenger. track only and had thousands and thousands thrown at it but the most fun I've ever had on 4 wheels.

[zollaf]

of course diesel can be fun, its just the big cloud of choking black smoke that follows you everywhere. go test drive a proper car though, like an s4, or s6, or rs something, a proper car, quattro so you can use all the power, petrol, so you can rev it. then you will know why diesels are for motorways. your mate, instead of blowing loads of dosh on an old beemer, he could have spent less on an rs6. thats 450 bhp as standard, then an easyish upto 750.

[GuitarGuy]

Not the point though, he liked the car, bought the car cheap, took the engine out and rebuilt the internals in his garage on a motor mount from scratch with stronger parts for example as and when finances allowed, its a labour of love over several years. Welded loads of custom bits and so on and so forth, he's a real whizz when it comes to cars. But basically it wasn't about going fast as possible or anything like that, it was more about learning for him. about doing as much work by himself as possible and learning on the way. And diesel so he could run loads of events without burning a hole in his pocket hence track only. but because its a small engine with massive power its a really unique feel. nimble yet absolutely brutal acceleration, whole car is stripped out so it weights just slightly over a tonne, not 2.

and i don't much mind the smoke lol :P

Also I can't test drive those cars because private garages won't let me, i tried already a few times to see what it'd be like to have all that power. they don't trust you unless you put a (refundable) deposit down for nearly half the car when you're my age.

[bobfish45]

I'm with you 100% zollaf. I love my 2.5tdi,but if I could afford an s or rs there would be no contest.

[GuitarGuy]

Thats what its about, affording it.

[Cave_Dweller]

I'm on both sides of the argument here. Yes petrols are fun and having owned an RS2 avant running 638bhp I know exactly what Zollaf is saying. But...on the other hand I went down the diesel tuning route myself and got my old 1.9tdi pd130 (which I think is the same engine as you're getting) B5.5 passat upto 260bhp and 500nm. I spent a stupid amount of cash on that thing and for putting the same money into a petrol I could have gotten a lot more power for my £'s. This website was heaven for me at the time and if you're wanting to head down the same route I did I can highly recommend them Darkside Developments - Home (http://www.darksidedevelopments.co.uk)

On the other hand though it was a lot of fun and the least suspecting car to fly past you. It gave a lot of tuned petrol cars a run for their money. For now though I'm sticking to tuning petrol cars as a hobby just because of the more bang for the buck and keeping a diesel estate for my daily driver. I don't fancy getting pulled over every journey either because of black smoke, which happened a lot so be wary.

I'm currently restoring an old E34 M5 BMW which I will be going all out on with the engine but keeping it looking OEM. Obviously I'll be changing suspension and everything else to cope with the power and to be able to put it down to the road but I'm not going to kill it by making it look like a ricer with stupid body kits lol, not into that at all. The E34 is capable of ridiculous amounts of power (1000+bhp), but I'm aiming for around the 600-700bhp mark. I could aim higher and it's easily doable, but I quite fancy a small bit of reliability along with power. If I went over 1000bhp I feel that something would break on every drive or need replacing every 50miles.

Hey guys. I'm new to Audi and diesels. Just got myself a2.5 tdi quattro with ambitions of one day soon pushing for around 300hp and 500nm. Do they really smoke that bad? Stock you couldn't tell mine is a soot chucker by the sound nor the "smoke". Or is this a thing that becomes apparent through excessive tuning and or over fueling?

[GuitarGuy]

If you run a diesel with increased fuel flow but don't up the boost you get incomplete combustion which is what causes the smoke. So you can get away without making it smokey assuming you have all the right bits. A GT2260VK, front mount IC, bigger injectors, free flowing exhaust and a fully custom remap and you should be there to be honest. Just get the engine checked out first because those 2.5 ti v6 engines can be prone to a couple of issues. Such as camshaft wear and i think it was fuel pressure pump or something like that. Im sure one of the other guys on here will be able to help more.

Thanks guitarguy. Is that'a tried and tested recipe then? I was hoping to change the turbo for a hybrid, update the injectors with a remap to suit. Would love to hear someone's "more experienced" insight on this though. I race motor bikes, an ok mechanic but am somewhat of a noobe in this arena.

Also known problems and faults would be great. I'm working on the car this week, trying to tidy up a few things before taking it into the family garage next thursday for a proper check over, certify my work and generally have another trained set of eyes go through her. If there's anything I should be looking for then I'd really appreciate it.

Thanks a lot for taking to time to reply too matey

[GuitarGuy]

I do my best, I'm no expert, Im just going on what I've read elsewhere. As for the performance figures I assume yours is the 180hp from the factory? Have a look here, Tuning Options for 2.5 V6 180bhp Audi A4 - TDIClub Forums (http://forums.tdiclub.com/showthread.php?t=213817) just make sure you keep reading as some people exaggerated the cam issue for example so stick with it.

Thanks mate! This is all gold!
