S3 and tuning curious

i am thinking perhaps in moving away from my APR stage 2+ S3 8p to a B8 s4 for a bit of comfort praticallity and the likes(was thinking rs3 also but kinda fancy change from 8p platform). but being quite a heavily modded s3 sitting at 380odd bhp n 400 tourqes on coils and big breaks i was wondering for some quick info on what kind of mods and tuning at what kind of cost could get an s3 to make me as happy as what current car does? i know there like 330 stock and v6 3litre turbo so i expect some good figures but what about handling and such likes, they bad with oversteer and is there common faults that i may like to keep eye out for? fancy a nice practical daily as i said fastroad/trackday spec ha :p

thanks

Cant really comment on a Stage 2 S3, but I had a Stage 1 APR S3 (circa 310bhp) and now own a B8 S4. I’ve only had it for 3 months so others will be able to give you more info than I.

I'd say that it would be quite even between a Stage 1 S3 and Stock S4, certainly not a great deal in it. I suspect a Stage 2 S3 would comfortably have the legs on a Stock S4.

S4’s tend to make over their quoted figured, circa 340-350 bhh stock.

Those are serious numbers you have in your car (have you uprated the turbo too?), which no doubt cost a fair few quid to get there. Assume it’ll take similar money to get an S4 to where you want it to be.

HOWEVER all that being said, tuned vs stock is hardly fair. If you were to spend 1.5K ish at a place such as MRC (Where I intend to go once my warranty runs out) You could have a Stage 2 set up giving you in the region of 480bhp and 580nm, which makes it a whole different kind of animal.

They are 3 litre SUPERCHARGED engines so the power delivery is very different to what you currently have, much more linear. There is no lag whatsoever.

Handling is good for what it is. I have the Audi Drive Select with Sports Diff and in Dynamic mode I think it handles very well indeed. It isn’t as nimble as the S3, given the significant weight difference but it has very high grip levels.

Bad with OVERSTEER?? No, in Dymanic mode you can get the car to oversteer if provoked.

If you mean bad for UNDERSTEER – dependant on how you drive / what setting you are in (assuming you get a car with drive select) it is prone to understeer in comfort mode, BUT in normal driving conditions I would say that it is better than my old S3 (stock suspension) which had far worse understeer characteristics. Yours will no doubt be different with the uprated ARB and suspension changes.

Common faults in early cars were the Water Pumps (which were replaced under a recall – check to be sure) and the Thermostats are prone to failure. Other than that that car seems to be quite robust.

From a personal point of view, I needed a car that was more practical as I now have a wee boy. I loved my S3 and was actually looking at getting another in sportback form. I couldn’t stretch my budget to the 8V, so it would have been another 8P. I’m glad however that I went down the S4 path, as it suits my need perfectly just now. Performance is good out of the box and with some money spent it can become so much more. Its plenty big enough in the rear for the wee man and his car seat / ancillaries which is ultimately what I needed it for. Wouldn’t change it.

There ain't no party like an S-Club Party.
Same for me. Stage 2 S3 and after another S car and need an Avant (man maths). S3 will give me 30mpg on a good run, and driven as expected. Interested to know the real world MPG on a S4.

I get less than 20mpg around town, but loads of fun with 480BHP on the twisty roads :)

MRC stage 2...the charger is very different from a turbo hit

I have a MRC stage 2 B8 S4 and it really does shift but still mega comfy and smooth. I average around 23-24MPG in mixed driving (mostly rush hour traffic, motorway, A-roads and B-Roads) so good for a 4wd, auto with 480bhp IMO. Came from a 400bhp Evo IX GT and before that a 340bhp Blobeye Impreza both of which were on coilovers and the S4 doesn't handle any where near as well with much more understeer but for added comfort it's deffo worth it.

Have to agree with that, came from a lowered supra and a lowered b7 quattro with rs4 arb and feel even in dynamic mode they handled better, but God did I get fed up of the crashy ride on our **** roads...
This is way quicker and so much more comfy
