K03 Hybrid

[lm_gauci]

When i had my 1.8T Ibiza having the turbo hybridized (sp) was a good alternative to going BT. Now i appreciate that the k04 can achieve good power over the ko3 but was just curious if anyone had hybrid thier k03 and what sought of power it puts out?

This was discussed a while back and so far as I know, no one has done it. The K04 isn't crazy money and is the best solution. You could actually go K04 and keep original injectors and fuel pump for 300-310bhp. You would have to get a custom map though as this isn't a setup that Revo, APR etc support 

That's a cheap-ish boost in power

APR do.

they have a few options already developed for K04 conversions on the K03 TFSI.

It was APR who gave me the idea.

• K04 with S3 injectors, stock intake, stock exhaust, stock HPFP  approx 300hp
• K04 with S3 injectors, Uprated APR HPFP, stock intake, stock exhaust, approx 320hp
• K04 with S3 injectors, Uprated APR HPFP, Intake, TBE and intercooler. approx 350Hp

Option 1 makes so much sense on the K03 TFSI as that 300Hp is cheaper than making a Stage 2+ K03 setup and it makes more power with less boost/stress.  Wish i had known about it back alongwhen i had my octavia tbh.

I was just purely thinking away from the ordinary to be honest. Ideally we would all save money by going straight to a k04/BT set up etc but most people generally do things step by step. Intake, then remap and so on.

I was just thinking that if you had a ko3 gti with all stage 2 mods could a hybrid ko3 be a good option. If its not been done though i suppose it could end up being costly finding a good set-up.

That's intersting. What sort of cost would you be looking at for the K04 and S3 inectors? I'm assuming that 300bhp option 1 needs to include a remap as well as the hardware?

is this really true?

They can be had for approx £500 second hand if yoyu keep a watch on ebay and fthe forums.

YTed mate.  I was chatting with Keith back along saying its a shame there wasnt an Octavia vRS wasnt available as a K04 as 300hp would be the sweet point.  He then highlighted they had developed these in the US. 

Makes sense really.

If you bolt a K04 turbo/injectors etc on the K03 TFSI engine then give it a remap for this setup, ie APR or RTECH custom, you have effectively made it the same as an ed30 stage 1.

But IMO lose everything the k03 has to offer. I think a 2+ k03 would be a better drive on UK roads than a k04 stage 1.

Hang on, do APR support K04 with original (k03 injectors) though?? IIRC Danish (or someone he knew) had run this setup on a Touran and made 300-310bhpish. As I understand it, the K03 injectors can just about flow enough for 300bhp.

That saves you the cost of the injectors and the fitting time. Perfect if you only want 300bhp 

[Janner_Sy]

That i dont know.  i presumed it was S3 injectors but never actually asked if they were needed.

But IMO lose everything the k03 has to offer. I think a 2+ k03 would be a better drive on UK roads than a k04 stage 1.

for a stage 2+ K03 with 280Hp (at best)

Intercooler £500
Intake £350
Downpipe £500 (Add another £500 for the cat back)
HPFP £350 (autotech is cheapest option)
Turbo Discharge/charge pipes £250
Remap £500
Total: circa £2-2.5k give or take different labour charges

Thats the car now maxed out on its setup.  Nothing else to come without swapping the turbo.

My Octavia S2+ was as quick as a stage 1 Ed30 on the road particularly so in gear, but maybe not flat out top end of the rev range, but that involved a loud intake, loud exhaust, high boost, etc etc.  It might be mildly better but not by a huge amount, and in a flat out pull a K04 would pull it due to the top end.

For me, i prefer quiet cars i dont like loud exhausts or intakes on an everyday car.  Had i known i could have got the same performance running the car less aggressively with the option of progressing further up the tuning ladder, this is without doubt what i would have done.

Stealth performance FTW.  All the performance with none of the downsides to modifying.

imo

Intercooler £500
Intake £350
Downpipe £500 (Add another £500 for the cat back)
HPFP £350 (autotech is cheapest option)
Turbo Discharge/charge pipes £250
Remap £500

£1200 gets you a very capable car with quick spool and you can have fun within the speed limit. I prefer a nippy to 60 car over a top end power car

Then you will only be looking at approx 270Hp, and without the IC (I have done this myself and the logs to prove it) you will suffer heat soak on the stock IC.  Something you might not be aware of until you log it especially on a hot day.  My car was hitting 80degrees IAT at stage 2+ K03 on a hot day, iirc Mikes car on the same day, same road running an intercooler had IATs about 50degrees cooler, despite him being stage 2+ K04

That £1200 would get you an extra 30Hp and be alot kinder to the engine/turbo as well, along with plenty of change for other mods.  The K03 is quicker spooling but its nbot enough that much IMO.  Certianly not enough to cancel out a 20-30hp deficit.

[Scottymon]

If you also factor in grabbing the intake / downpipe and HPFP second hand you can knock quite a bit more off too.. also map for £300.

[Janner_Sy]

Lots of K04s on ebay for sub £500.  Bit of bartering and you'll get that lower.  Factor the £300 map in and thats 300 Hp for sub £800

I ran revo and had it logged and RR and was fine, not as cool as when i fitted the cooler but still ok. to me its about enjoying the drive and the k04 just doesnt feel as good as the k03 when nipping around town and to 60.
