K03 stage 2/2+

[Joshryan]

Hi I'm currently running stage 1 on my gti at 242bhp I have since added an intake and next is the decat downpipe.
Before I go ahead with stage 2 I was wondering if I added an s3 intercooler and also an uprated fuel pump what difference in results I'd get? Or should I just stick with the basic stage 2 mods. Thanks in advance to anybody who has any info.

I'm thinking k04 in the long run but for now I want to see how far I can take the k03! Thanks

I have same kind of setup in my mind, atm I have S3 cooler and MTC intake installed. I will also install Milltek downpipe and Autotech hpfp internals. Wondering also what else should I install before I have my car adjusted in dyno. With ko3 is there need for S3 injectors? Eventually I think ko4 will be the way, but not right now..

[Joshryan]

I think similar then if I go for k04 more of the setup is ready. Wondering how close to 300bhp you can get on k03. I know they run out of boost high up the revs

[Wildengti]

Are you running a decat for high flow? Which dv have you got too? Have you changed the pcv?? Sorry for question but thinking about goin straight to stage2.

I run a bluefin stage 1 currently which is good but lacking in a lot of ways..

My plan is the intake next, then miltek sport cat downpipe. Looking to take it in to R-Tech to get stage 2 minimum but I was also wondering what else I would need to do to push it to stage 2+.

I realise brakes are going to need an upgrade at that power so that is also on the list.

How neccessary is it to upgrade HPFP?

[greygti]

R-tech say they have never needed a upgraded HPFP for ko3 stage 2+ niki said he only ever recommends them on ko4 stage 2+ , the ceiling limits of a ko3 stage 2+ even with the best flowing parts and map is around 290 bhp

[cobz]

I don't see me ever feeling the need to upgrade to KO4 so not needing the HPFP is good news.

So the list will be:

Intake (probably ITG)
Brakes (S3/R32)
Milltek sports cat downpipe

Is the intercooler completely neccessary before the map then?

300hp is just about possible...

Best I've seen was I think 285 from Niki on a Cupra R,

S3 cooler
Intake
Full TBE


I got my stage 2 mapping on 8th July @ about 108k on stock k03s with decat (stock rear section) and intake so see how that goes!!

If I get a safe stable torque 260bhp I'll be happy.

Who's Tuning it Jay?  Are you getting the DSG done at the same time?

Rtech are, and yeah getting DSG map at same time, cost is £500 :)

Great choice 

Haven't read an R-Tech K03 review for a while, looking forward to your feedback mate

So hpfp not needed for stage 2+

Doesn't sound like it for R-Tech. Revo & APR do need it

[Stig_gti]

Ok thanks for that I'm going to get mine booked in at r tech aswell then
