I'm building a budget Track/drag car, with handling/track being the primary focus. But It will probably be doing time at Santa Pod with the VWDRC next year, If things go well.

 

So what is it? It's an early MK1 Audi A3. Known for the moment simply as 'The A3'. It's a tatty looking S reg (1998) 1.8T and it cost me a whopping £150.

The first port of call for any race car... it went on a diet!

I stripped out the seats and quite a lot of the trim, but the dash, carpets, headlining and boot trim are still fitted... for now.

 

Then I started crossing off faults one by one, starting with what I through was a knackered gearbox mount... Turns out someone has sheered 2/3 of the gearbox bolts, so it was wobbling around on one loose bolt :o

 

Drilled through them suckers though and nut/bolted it. Job's a goodun. :Y:

So there you have it, the first instalment of the race car. There is much to do, may parts to buy, and a lot to learn, but basically this will be a budget track toy that I plan to build for £1K.

 

Stay tuned...

Only £78k! On a separate note good luck with the build. I'll look forward to seeing the updates. Are you planning to keep the car street legal?

Oh, I also like the air cooled tin kicking around. Used to have a bay window in that orange many years ago.

Just a stock diesel Anni................well almost  :new-chuckle:

Cheers lads, i've already chewed through over half my budget, but i have brought new tyres, front brakes, a lambda sensor, oil filter, fuel filter, timing belt kit, plugs, and a few other bits and pieces. Next up is coilovers, and a new battery. It's also getting a LCR suframe, quick rack, arms and uprated ARBs thanks to Jay p. And yes, the car will be staying road legal, as i'll need to drive it to events (dont have towing license)

Oh and i forgot to mention, I picked up a Wizards of NOS kit for this car a couple of weeks back. It was too cheap not to buy. The fully programmable progressive controller alone is £400, and i got the whole kit (bottle, heater jacket, bracket, solenoids, jets etc) for £250. Not counting towards the 'budget' as it's not a necessity, It was just too good to not buy.

 

That's more for the drag racing aspect of the car though, and wont be going on until I put uprated rods on, which wont be until winter I think. I suppose i could safely run a 50 shot though, if i really wanted...

 

Look forward to the progress on this

 

Thanks man, i'll try not to disappoint! Many packages are inbound.

I was wondering how long it'd be until you saw this thread ;) I'm probably going to keep it as DIY as possible, as I want it to be my labour of love, and put my own stamp on it, so to speak, but if i need a hand i'll give you a shout :)

 

I expect to see you at lydden hill for Apex festival in May. It's a brilliant show, and track time is cheap! PM me if you're interested as I have a promo code for 25% off ticket prices. Apex festival will be this car's debut.

Gonna just run the K03 into the ground this year, nice and cheap, don't have to worry about killing it.

 

My girlfriends brother Carl has a cast T3 manifold kicking around that he would practically give me. So anything on the T3 flange, which gives me a lot to chose from.

 

300hp would be more than enough I think. But we're talking long term now.

 

Right now it's running a factory map, at only 7PSI, hasn't got a lambda sensor at the moment either but it drives okay.

Haha being that it's an got the old me3.8 ecu, for a cheap bit of temporary extra go you can stick a bleed valve on the n75 to get it to boost up to 14psi before it hits fuel cut ;)

Yeah i think i'll just whack a manual boost controller on it and leave it as is until i go standalone management.

Step this way....I've got a couple of sets rear 256mm calipers and one set of carriers. Not sure which is up for grabs at the mo but I'll keep you posted. Note one set needs a good refurb.

Got a pair of superpro rear axle bushes going up for sale later. They're from the track bora but only covered 4k and are solid.

Just listed some braided front brake lines in the classifieds.

Suspension can't help with that one but if you're doing limited mileage a cheaper set will suffice. You'll want height adjustable though so you can rake the stance for drag launches..

Reminds me I've got some 17" drag radials in the garage too....

The braided lines i'd be interested in, and i've got my eye on some FK Konigsport's like i had on my V5 (liked them alot) but the condition is unknown. The beam bushes might also be handy...

Minor update this evening. The bottle heater jacket from my nitrous kit I brought was damaged, the wires often get damaged and fall off/fray probably due to the heat and stress they are under, as they're soldered directly to the heating element, when really they should be crimp/screw terminals or something not susceptible to heat.#

 

But anyway, I haven't re-engineered it, I just replaced the wires with some high quality 4mm silicon. Much more flexible than the factory wire, because of the massively high strand count, and it's also heat proof. Once I soldered the wires on (spaced them further apart on purpose) I bonded everything back down with sealant,

Some hard graft went into this at the weekend. This morning I was broken. Aching all over, paracetamol just to function without groaning, plus a cold and generally feeling unwell, it's been rough.

Call me a wimp, but I started at 9AM on Saturday, worked through till 11PM with help from JayPButler a pub lunch thrown in there somewhere around 1. Then i was back at it 8AM sunday morning and didn't wrap up until 9PM, having eaten only a bacon sandwich and a hot cross bun all day.

But enough about me and my ailments, what about the car?

Well I now have a Leon cupra r subframe, control arms, quick rack, H&R front ARB, 312mm front brakes, and hubs. More on the hubs in a second...

A3 on the ramp:

20150328_110612_zps1e1qyl09.jpg

Big advantage having a girl friend who's dad is a mechanic, with his own workshop, where the fun and games can happen.

Jay's Cupra in place, ready to donate it's organs to a good cause:

20150328_132401_zpsouqzsknu.jpg

First thing I did was drop the subframe off the A3... Easy job... when you know where all the important bolts are, which I didn't. But it did make it easier second time round when I had to take it off the Cupra.

20150328_172902_zps7ienhoc9.jpg

blury picture of the broken cupra:

20150328_172913_zpsbu7nb7wb.jpg

Then while trying to remove the adapters for the big brake kit on the cupra, this happened:

20150328_211608_zpspcr1wvcv.jpg

So I practised my welding skills, which are FAR from perfect, but it did help extract the stud.

20150328_211903_zpsr7elcand.jpg

Tired, defeated and rather peed off, I went for a shower and bed.

Fresh start in the morning and I started by taking the subframe, and all other related paraphernalia off the cupra:

20150329_104733_zpsipcjazjb.jpg

20150329_104547_zpseyocluta.jpg

I then lifted it on to the A3, and started nipping bolts up. At which point Jay turned up again and we continues horsing around with the welder and breaking things. I kept miss-placing my tools, and hitting things with hammers.

LCR subframe:

20150329_105920_zpslq4ijuai.jpg

Note the cut ball joints. Would be fair to say I was starting to regret taking on such a task. Every bolt on the cupra seemed to either strip the head, or start undoing, then bind up completely. I had to cut the ball joints and brake carriers off, which ultimately left me with two buggered track rod ends, and a knackered hub.

But despite the trials and tribulations, We managed to get both cars back with 4 wheels on, so we could free the workshop up for Monday morning, when 'proper' work was going to be done.

20150329_204012_zpshngmng0l.jpg

While I was doing the subframe swap, i put my newly acquired 312mm carriers and discs on, which has filled out the wheels nicely:

20150329_204908_zpsfuik7ej2.jpg

And finally, i gave the car a lambda sensor, which should help it fuel a bit better:

20150329_204926_zpssbk0cq6f.jpg

One of the hardest weekends of work of my life. It really doesn't look like much when you write it all down, but it was a solid weekend of work. Would be quicker next time round though, now I know what I'm doing!

Also, a potential name was born for this car, when i messaged Jay late Saturday night, saying Seat+Audi=Saudi...

You have done the right thing adding that lot ..... makes the car handle from shoot to good.

 

You will need a rear ARB to match that front or you will suffer from understeer still.

New tie rod ends and balljoint are already on order, as are some new knuckles. Gonna get some bew bearings too and just swap the whole lot over when the coilovers go on.

I do hope so! Rear beam is getting polly bushed and roll bar'd soon :)

6pots, actually! with ECS floating rotors front and back. The thing about a BBK like that is they're way over my budget, you have to run 18" wheels, which means buying 18" track day tyres... expensive! And they wouldn't actually help me all that much on a track!

 

312mm front + 256mm rears, in a stripped out car like mine should be more than enough i reckon. Decent pads, braided lines and cooling ducts would be the only other brake mods I would consider at this point.

I agree for the most part, the other bonus with using smaller brakes is you are not adding a huge amount of unsprung weight. I'm sure I have read somewhere that 1kg of unsprung is equal to 3kg sprung.

 

Im off to brands at the end of april so ill let you know how my 312's hold up, I have a feeling that if its a nice dry day they will start to cook though. I think the LCR 4 pots will be the way to go if this is the case as they just fit under 17's which is still a compromise but may be necessary.

 

If they are fine though ill probably go the other direction and look at lightweight 16's with low profile tyres. which should help unsprung weight and give a bit better acceleration form the overall drop in wheel size
