View Full Version : Getting More out of the 1.8 20vt?
I am trying to pin down some of the things that you can do to improve power on the above car on engine modifications only:
Chip
KO4 Turbo
Induction Kit.
Anything else that you can do and any information would be gratefully received and also any info on the KO4 Turbo as I know sod all!
Cheers.

Exhaust and downpipe/cat, but probably only on very high power conversions. (like 300bhp)
Don't forget the brakes and suspension. These would be on my list of things to do before more power IMHO.

I personally wouldn't bother with a KKK04 turbo. If you going to all the trouble of changing the turbo you might as well put a decent one on there!
Talk to Mike @ Jabbasport, IHI roller bearing turbo's sound so much better and very close to the price of the KKK04.
How bigs your wallet Si?
Bill,
Brakes and Suspension done now hence looking at power bits and pieces.
Steve ........ Interested in your ideas and as I am not too engine technically orientated would be interested in hearing more?
Cheers.

No problem Si!
The kkk turbo's all work the engine to hard with loads of backpressure. The engine is trying to spin the turbo but the efficiancy of the KKK lets it down .
The roller bearing type turbo's when matched to a flowed manifold and give very little back pressure so the turbo doesn't have to work the engine as hard and will spool up a lot better with less lag and can boost very efficiantly and rev freely.
Also KKK04 turbo £745 +vat
IHI turbo £785+vat
The intercoolers on the ibiza's are total poo (about the size of a A4 bit of paper folded in half!) so a bigger one or a charge cooler is a must.
Iam going to see what the charge cooler does for my car as it does get far to hot very quickly and then go for the IHI turbo option.
Do you still want a write up about the chip and boost controller for the SDC mag?
Steve,
Thats cool, so how much money wise would you be looking at to have the Turbo that you have suggested and who does it, Jabbasport? Coukd you run that without a chip then as well?
All info greatfully received!
As for the mag write up mate, I am not a member if SDC now so I would submit it to Zboyd (Mark Forbes)
Cheers.

Also try looking at a Garrett turbo.. something like a T25 or the like..
APR-Europe provide some info on their choices of turbo on their website covered under the stage II and III upgrades..
Good Luck with ya mods..

If you get the opportunity of comparing the exhaust manifold of the K03/K04 engines, you will be amazed at how small this thing is. The bore is tiny, and I mean TINY!
The IHI conversion from Jabbasport is nice in that its a relatively large turbo, but with minimal lag and quick spool up, partly due to the low inertia construction, and roller-bearing bearings. This is mounted onto a Jabbasport manifold, whcih has larger borepipes feeding the turbo, so restriction is vastly reduced. - A major limiting factor of running high boost from the K03/04's is that they themselves, become the restriction in the system..They are so small and are incapable of flowing enough air for high power applications.
The same would go for the Garrett T25, T28, T3 or larger turbos. These are larger turbos which need suitable manifolds. APR have a nice precision cast manifold for their Stage III kit and I believe full details are available from their website.
As Steve has said, you would be best advised to speak to these tuners directly to get the full SP on their offerings.
Jabbasport and APR are the obvious people to talk to.
"To go fast cost ££, how much ££ do you want to spend?" - the old addage still rings true.

Bill
Cheers Guys ...... Its always money isnt it ;)
Gonna ring Mike@Jabbasport this week and see what the options are!

Si,
Would be interested to hear your fiindings, as I am pretty much in the same situation as you now, I want a chip but am not sure who to throw the money at! Jabba sounds like it is edging into the lead at the moment though... keep us informed!!
:cheers:
Ringing Mike in the morning to go through all the options and prices so will post tommorow!
Si
Had a long chat with Mike@Jabba Sport today (good job fone is free)
I am going with the ECU re-map, but did discuss a Turbo Upgrade amongst other things and I will stick with the re-map and see how things go!
Very pleasent chap and explains stuff very well to you and cant stop talking!
So June time it will be going in, and I hear that Bill is going for the big 300BHP??????
Si
so your keepin it 4 the time being si ??
Hey Ben....... Cmon mate what dya think? Are you keeping yours?
God Knows!
Si
im keepin her 4 the mo m8, but i do have a cunning master plan.
me last 1 was brought 4 4k and sold 4 6k a year l8r with an xtra 10k on the clock:D :D sometimes im just a jammy f*cker hehehe
Ah well you will have to let me in on this matster plan young SIr!
Si
not really a master plan u just gotta know who,when and where 2 sell and u can get lucky:cool:

Si, did you get qouted a price? I rang on tuesday and was qouted £ 280 + vat for the chip, and an optional boost controller for £95+vat. The boost controller sounds likea bit of fun but to be honest I driive the car hard most of the time anyway so don't see the point of having the switch as I would never turn it down!! I was also told that the car would reach between 200bhp and 215. I am not so sure about that after hearing about other chipped cupras not even reaching the 200bhp mark. What are your thoughts?
I presume that £280+VAT includes fitting and a RR session (because they map it to your particular car). Which means
it is the same price as an upsolute. So, I have seen a plot
of an upsolute chip but I don't think I have seen one
for a jabbasport one. I like the idea of the torque of the
upsolute.
Is it worth getting a RR when having an upsolute. Obviously
it will tell you how much you are developing, but I presume
there aren't too many things to tweak, so is it a case
of just giving you a nice warm feeling?
Also, how much extra have people been stung when informing
their insurance company of a chip? I have just spoken to
Adrian Flux and they want £1200 (with a chip), tescos want
£950 (without a chip).

The thing that appeals to me with the Jabbasport chip is that Mike will map it to your requirments i.e. if you want huge torque in the begining he can do that or he can flatten the torque curve out and give you smooth power delivery if thats whats preferred. This apeals more than an 'off-the shelf' chip as top end doesnt really interest me as there is nowhere to use it. My number one priority however would be reliability, I dont want the car to overheat in traffic and I don't really feel like rebuilding the engine every 10 000 miles! I would sacrifice 10bhp for reliablility if nessecary. My understanding is that the £280 includes two dyno runs - one before and one after, and the work on the chip obviously.
CupraSport2000,
Well the good news is that Mike said almost excatly the same thing to both of us!
It works out at £330 inc VAT and he will do a RR afterwards and when I asked him if he does one before he said if the customer requests it!
I must say that Mike spent a long time on the phone with me going through it and explaining it to me a non-mechanically minded person and I am extremely happy with his attitude etc etc!
After reading a lof of the stuff on Chips recently I feel that I am doing the right thing in going to Jabba Sport!
Good to see that we are getting the same info, oh and about Power, Mike said between 200 to 212 dependent on mileage etc etc!
Cheers.

Hi Si,
I think I am getting the same vibe as you from Mike, I like the way he conducts business so far and I appreciate his honesty and patience in explaining all the details. I have not heard any negative feedback on him or his products and am quite keen to get this work done now. I do think I am an 'emotional buyer' and the attitude of the company I am dealing with goes a long way in securing my business. Unfortunately the opposite attitude is so often encountered - amazing that these people are still in business!
I would however like to hear from people who have had the Jabbasport conversion done - what are your experiences and what do you think of Jabbasort in terms of aftersales service? Please let me know...
CupraSport2000, best person to speak to is Whelme (Wayne) he has the re-map and boost jobbie and I rang him at work )ooops) and he spent a while going through it all with me and thats an independdent view as Wayne has the Upsolute Chip in before so he can give you a good comparison!
Jabbasport have a bloody good name in the VAG World and have been around for years and at the end of the day all you wanna hear the the truth and no bullshit and thats what Mike has done (am i getting paid for this plug?)
Speak top Wayne as like I said he has the re-map and then Its down to you to make your mind up, I am 99.99% certain now even if its just off Mike Attittude and the fact that I have not seena negative post!
Cheers.
Si

Your car will actually spend about 2 hours on the rolling road, so with each one taking about a minute you can work out that that is not two rolling road sessions!
It actually takes longer to fit the boost controller than it does to Remap the car!
Unfortuantly there is no point running full boost all the time as the air in the intake will get to hot and the ecu will retard the ignition, i find its better to run it with less boost for long sessions and full for that quick Saxo eating sprint.
I can't praise Jabbsport enough, The customer service is second to none and as you guy's have found out, Mikes very friendly and quite happy to explain things to you. Do note tho, save any questions for when you go there as he is a busy chap and some poor bugger is standing there watching you talk to him instead of re-mapping his car!
Go for it! you won't regret it!
Mines overboosting at the moment, seems that the blitz is dragging in two much hot air from the engine bay and the ecu increases boost to try to compensate and BAM no boost at all :mad:
Cheers Steve, some good points and I am looking forward to being Jabba Sported!
Not one bad comments ......... seems good to me!
