Hi everyone!

My car is currently stage 2 and I want to take it that little bit further without doing a k04 conversion.

Can anyone recommend a good K03 hybrid or somewhere that manufactures turbos. Id rather a straight bolt on bolt off option to save changing pipework and other things.


Thanks
 
I really think you should go with the TTE420?

To be fair your 100% right the TTE420 is the best option but its not plug and play due to it being a k04 hybrid, do you no any suggestions of k03 hybrids, product numbers would be great!

On a TFSi,you may need to be careful of torque with a TTE420,as the TFSi rods aren't as tough as the S3 rods.

For sure,the TTE420 is a better turbo,but also capable of delivering a lot more torque than a K03.

Im running stage 2 at the moment, with a R-tech stage 2 remap producing 278bhp 328lb/torque which is strong for just a stage 2 but i want a bit more without changing the pipework, if there isnt a decent k03 hybrid to get then along with an upgraded fuel pump what other mods can i do to increase power even more?

Ive emailed a few turbo fabricators to enquire about a custom hybrid turbo build but i just wondered if there was anything prebuolt on the market?

Speak to @TTE Si (Simon @ TTE) as they do a range of hybrids which may suit your needs.
For instance they do a TTE320,which is a K03 hybrid.
Also,you shouldn't run the risk of bending rods with something like that.

If you start reaching for a lot more power,you would need to consider building the bottom end of your engine.

That sounds more like it ill message him now, cheers mate I appreciate it
 
Personally I'd go for the K04, the only problem with the K04 on stock TFSI rods is that the K04 has a spike so you'd have to have it mapped to take that into account unless you did the rods - or as S3Alex said, TTE do K03 hybrids but it'd probably be about the same cost wise to just do the K04 swap, ok there's a few bits of pipe and the recirc relocation to buy but it's the same job to swap either turbo!

Ive just messaged TTE enquiring anout the cost, if it turns out to be around the same cost i may reconsider whether its worth doing it all together and just buying an s3 because really i dont want a k04. It defeats the object a bit and when you add up the cost of the car plus a k04 conversion you could just buy an s3. Plus i wouldnt want to be changing rods and co. But again i agree with you if you look at the bigger picture the most favoured choice everytime is most likely going to be the k04 conversion
 
I think the best way is to decide what sort of power level and performance you want to stop at,and then you have a better idea of what's required.

For instance,if you went to beyond 440lbs,you would need an engine build irrespective of whether you had a TFSi or an S3.

Other than that,the S3 engine is good for 440lbs without a rebuild,and grain get can give you excellent advice on the TFSi.

I want about 310-320bhp and 360-370lb/torque ideally im open to advice from everyone on here as most of you have been there and done it already
 
Easy with an S3 engine but need to consider rods and torque rating with the TFSi.
It may be OK but you'd need someone to confirm that.
 
The bending rods, its a revision related acctualy, some bend it with stock motor, and some runing k04 swap and nothing...
If you really cant live without the power, go for it, APR\IE rods are not that expensive ;)
 
As S3Alex has said, decide what power you're after, ask simon at TTE if the hybrids are suitable for what you're after. FWIW my AXX did the K04 no problems but was mapped to suit the weaker engine although has been running 325-350 maybe more with W/I, think I had the K04 on that getting on for 20k miles and I can double check that non of the rods are bent - I didn't notice any being bent when I had the internals out but I ended up going CDL as my balance shafts went bananas shortly after doing the pistons and rods unfortunately!

Been looking at the same myself, everyone points to the TTE420 even TTE said the same. But as you mentioned you dont want to do rods pipework, exact same here you want a bolt on KO3 hybrid so your looking at BBT beach buggy turbos who just been taken over recently or the TTE320 i cant find any price on that, then your looking at custom mapping as well once done your looking at 340-360 according to previous conversions
 
At the small increase of power you can achieve by purely going K04 it almost isn't worth it. Most people who have done K04 swaps noticed a smoother power band and slightly higher top end, but why spend the money when you're going to want a big turbo in the end? You can't push the k04 anyways without a bottom end rebuild anyways. Pony up an extra bit for at least a gt28. There's no point in 20 WHP gains for the cost you will spend on the barely larger turbo.
 
I wouldn't entirely agree regarding the "small" increase with the K04, it's a considerable step up over stage 2 on the K03 even running it up to what the TFSI's will take depending on whether you have an AXX or BWA and what your mapper says they are ok up until. If you went for a K04 then you'd know if you wanted to go further an build the engine or limit the torque and just stick with the K04 - If you've got a good K04 then you could send it off to TTE for hybrid-ising while you're having the engine internals/engine swap done.

Yes you could go BT but a K04 upgrade is still very reliable and a good daily driver as they still shift!
