Following on at a tangent from the APR/Revo threads started today by jaymd and Lloyd55vrs, I have been wondering.

My car came with a healthy list of mods. I nearly rival Bowders for a long sig of mods although don't profess to have the same knowledge

Which leads me to ask why exactly would a Stage 2 APR , ARX K03s powered 4x4 have any the less BHP at the flywheel than a Stage 2 APR AUQ powered VRS?

I don't know the figures for the car. i realise only a RR session on a reliable RR is going to give me the answer.

Until such time as I can do this, is there any reason to think I would not expect to see between 225-235bhp you guys with VRS's are seeing with similar mods to my 4x4?

Cheers

Cheers for the comments

As far as I am aware I would state you should see the same power as a VRS, as the post 2001 4x4's all had K03s turbos as per the VRS(someone is bound to confirm this).

So depending on the RR being run, the output you mention is acheivable, 235 BHP being the very top end and mostly not repeatable on different RR's.

... post 2001 4x4's all had K03s turbos as per the VRS(someone is bound to confirm this)...

Yep, its a K03S fitted to the ARX I've just taken out of my car - a 51 plate

I believe that the 4x4 might actually make a tiny bit more power with like for like mods and the same map, as the twin Cat is less restrictive than the one on the VRS (obviously negated when the Cat is removed )

do the post 2001 ARX's still have the power capped at 150bhp standard?

do the post 2001 ARX's still have the power capped at 150bhp standard?

Yup. All the Mk1 Octavia 1.8T's had 150bhp, with the only exception of the AUQ in the vRS.

yep - those where the orders from vw ...

All the above are correct, same basic engine so same mods give equal power. I would also agree that 235 is hoping for a lot. The only other difference is the power is more usable with the 4x4

The 4x4 is also slightly lower geared so theoretically could accelerate quicker. Top speed is thus slightly less but you will still see 150 on the cliock before you hit the limiter. If you want to raise the gearing the VRs gear cluster will fit straight into the 4x4 box

You will find in the 4x4 the clutch works a bit harder & may fail earlier, the vrs releases excessive power loads by spinning the wheels thus saving the clutch. The 4x4 just grips

If the clutch dies do the Corrado G60 conversion, there is a good thread on here somewhere so do a search. That was good for 255 bhp on mine. The Haldex will take all you can throw at it so dont worry about that, just make sure the oil is changed at the service intervals, I think its around 40K but check. The std gearbox will be Ok, I swapped the VRS internals into mine as even with the limiter raised I was hitting max revs in top (160) with the 4x4 gears & it only broke when I was running just over 350 bhp, cured by fitting the TT 6 speed box. I still miss the 4x4 but I guess you move on

Shame the W reg Audi's dont have the K03s fitted as standard...

Just found out some do!

Interesting info thanks to all. Useful to know from members that have done big power mods to a 4x4 - Stuart_J' - didn't your car have a big turbo conversion as well?

TBH I don't think there is much more that can be done to mine without spending big money. It already has most of the engine, drivetrain and suspension mods that can be done.

I was struggling to find a reason why so many tuning companies quote a mechnically identical engine with a lower power figure, assuming they are using the same map on K03s equipped engine (ARX, AUQ or AUM). Can only assume they are quoting for the earlier non-VVT K03 cars.

Since found AMD Techniks website figures make more sense as they quote upto 50-60bhp for a ARX/AUM or upto 30-35 bhp for an AUQ. Thats not to say other tuners would be any different, but I was just going on quoted figures and appreciate every car will be slightly different.

So a RR session will be on the cards. I insured it as 235bhp so by the sounds of it I am not too far off.

I will continue to love it for what it is - nothing else I have owned has given the same fun per pound so far.

I had the IHI conversion by Jabba & strengthened internals, carbon Clutch, TT 6 speed conversion as well as a fortune on chassis & brake mods. I think where you are at is a great place to stop, avery quick car & not to expesive to keep it running, just enjoy it. If you havent done anything to the inside the Black Leather recaros out of the Golf fit & the rears fit to match, this gives you a lot more support in the front & they blend really well with the Grey interior. If you have Tan the same from the A3 will fit & match in with the Leather wheel out of the Octy L&K

What did EddyH's have? 440bhp?

What did EddyH's have? 440bhp?

Allegidly a lot more than that although when Badger Bill bought it he found it undriveable & detuned it to make it useable, I gather It was very linear power delivery & took an age to wind up, OK on top speed runs but not the best on bendy roads & for every day driving

it never had the right turbo fitted as far as i can tell, even badger still put on a laggy turbo from what i remember, and the map the engine came with still was setup for huge power rather than quick spool, something that is being corrected as we speak with a far better suited turbo and map going on instead

Glad to see its being sorted, Less power with a wide powerband is quicker in 95% of conditions. I can remember slaughtering a 600 bhp Supra in the alps with a mere 225 bhp on the 4x4. With the IHI & 356 it was still fast in the twisties & kept up with a Ferrari 360 on an Italian Motorway

I will say I told them so quietly & slope off before the flames arive

why did you sell it Stuart?

why did you sell it Stuart?

I had it from virtually new, ex demo & built it up over several years mainly for cannonball runs. I did 3 runs in it & about 80K in total. Then I was offered a 350 Zed twin Turbo at a very attractive price with low milage so decided on a change. The Zed with around 500 bhp is a very different car, slower on the twisties but you get a big grin when you give it the beans. I still miss the Octy & maybe I should just have put it in storage. It cost a fortune to build, Im guessing I spent around 25K & got a fraction of that back but I guess times move on.

That's the theory

thats the problem with modded cars, they always cost a fortune and give you a fraction of that back when you sell them.

I remember you posting about the cannonball runs before, bet that was fun, still sounds like you have a sweet ride now none the less!!!!

True.

But when you've got an addiction, you've got to feed the beast !

I totally agree Stuart. I bought the car over a Vrs or another impreza because of the mods and full documented history. Given the price/age/mileage/performance and practicality, nothing else comes close for the money. Looks almost standard too which adds to the fun

I popped into Jabba to get a fault code checked and found JP and Brian really helpful. Whilst there I noticed a Mk4 Golf on the ramps. Owner was spending £13k getting the engine rebuilt to 1.9 and 400bhp+....

I have fitted a VRS steering wheel and carbon console trim and am looking at fitting either a Leon Cupra or Golf Mk4 grey cloth interior at some point. Never been a great fan of leather interiors. Will probably fit 17's from an S3 or Leon Cupra too, but then thats it, other than ongoing maintenance.

Doing Cannonball's in a modded Skoda? Bet you had more laughs for your £25k than the other contestants though!

Ive had an Impreza as well, complete money pit & just not rewarding to drive so yopu are lucky you avoided that. The final straw was when it blew a head gasket (on its replacement engine) at Imola on the first cannonballrun, came home on a lorry & we had the fastest rental focus in Europe

The Cannonball in the Skoda was a blast & it gained a bit of a reputation. With a verified max of 170 (speedo was starting the second lap ) it couldnt keep with the big boys on the motorways but as soon as the roads developed bends it was more than a match for most, best result was second The other big plus was the Police were always after the exotics, I was waived through onee stop in spain & also managed to run a Spanish Motorway road block in it although that was thanks in the main to a great truck driver who shielded me, great memories !! Had a couple of other tugs but never a ticket

All credit to Jabba for building the car, it got absolutely ragged & none of the work they did ever let me down.

Re interior I was never a fan of leather until we had it on Wendys L&K & its just so easy to keep clean, marks just wipe off but cloth will be a lot cheaper, just make sure you get seats with much better side support.

Another good mod if you havent done it is to fit R32 Antiroll bars ( 2 sizes, get the thicker ones 22mm I think) , stiffens the whole thing up, for the rear you will need to put a dent in the spare wheel well to fit it, I know Bengie & Eddyh did that so they could advise, I had a bespoke one built for the rear by Jabba but that was from memory £300 + fitting & about 6 years ago so more now

Cheers, yes it was fun, we now do private runs with less than 10 cars & have our fun off the motorways, Have a great time & avoid all the hassle from the Police. This year we ran down through the Pyrenees, spent a few days doing some of the tour de france routes, they give great climps with imaculate road surfaces & then on into Catalunya where we did many of the rally stages (its a tarmac rally) Again fantastic roads but how the hell they drive them as fast is beyond me, total respect for those guys.
