In need of power

[kaneda]

I recently installed a Frankenturbo kit after my KKK K04 self destructed and liking it so far
Defiantly at the "affordable" end of the market seeing you get a higher output K04 ,TIP and high flow exhaust manifold for around 1K .

yer would love to get turbo but not sure on the instal as i would want to do it myself, just spoke to a bloke from a performance shop and he says with a full exhaust, fmic and bluefin tune ill see around 250hp(flywheel) so might look into it a bit more and get a price off him aswell.

No way you'll get 250 without a turbo change, unless they are mini-horses. Even a K03s maxed out with FMIC and a full system, can't get there, let alone a K03.

If you really want more than 200hp at the crank, you should be growing a money tree.

Your turbo isn't going to suddenly quit at 110K, assuming the car has a service history, it'll most likely do twice that. Other considerations for you. Having more than 200hp is likely to highlight other parts of the car that need attention. Like the brakes and clutch.

The clutch is the thing most likely to need replacement at 110k. There's $500ish even if you can fit it yourself.

Unless you can rustle up a fair bit more money, you'd be best doing a downpipe/exhaust and flash.

what he said ^

Although i gotta disagree about turbo's! k03s are junk, and might as well be swapped out,
not that expensive to buy a k04, the k03s are on borrowed time from factory.

I am talking about the K03s from the late model Golfs which never came to Australia. Also fitted in the Leon Cupras and the like. Usually running 132KW from the factory. The straight K03 off the AGU is a bit asthmatic, 50 hp from software isn't to be laughed at though.

Calling them junk is a bit harsh IMO. If you wanted a turbo that is generally reliable for the everyday driver, I don't think you could say it does a bad job. The last pretty well with normal servicing. When they get older and the quality of servicing declines, that's when they start to fall over.

The k03MS? Thought the Leon Cupra R was the BAM code engine tweaked a bit but had a k04.

slightly better, yeah. But the k03 is just nothing, cant flow bugger all without creating massive loads of heat!
k04 same boost and you'll have 0 reliability issues. Take an Audi b5 //S4 for example twin k03s.

You need to drop the whole engine/subframe when one goes pop, would you replace them with another set of k03s? Hell Nah!
I've seen so many people who drive their MK4 gtis and polo gtis hard and bang, time to upgrade!

Not to replace for another turbo designed to give great low down torque but has nothing up top.
I just think a k04 to buy, its a no brainer, k04/ fpr/ pump/ dump back/ intake/ tune and maybe injectors. 250hp done and reliable.

The Cupra was before the R which did have the K04/BAM motor as you say. I guess it depends how you drive. I don't rev the ar5e out of my S3 as you make a lot of noise and attract attention. Using the torque is the way to go.

Upgrade when it blows up for sure but there's a lot of work and more than 2K to do a K04 into a GTI with the right amount of supporting mods. I have done it and you could do 5K easily.

You have the prefacelifted //S3 then? the k03, isnt it just a k03 not the MS?
The later models had k04s i think. either way, back to the OP to get 200 reliable hp,
you'll want to upgrade to a larger flowing turbo.

Agreed Gavin?

The k04 will keep most of the torque down low and give you lots more power up top, flowing enough that when you wind the boost up,
you'll A. need to wind up less to achieve the same power/torque figures as the k03, and B. produce way less heat,
netting a more reliable engine, with a turbo and electronic/other ancillaries which are less likely to fail under medium harsh to heavy driving.

I think a kit could be made up for around 3k, or just above, if you shop at the right places.

Mine is a 2000 8L originally APY/210hp/154KW engine. It's always been a k04.

MK4 GTIs suffer from inadequate intercooling when the wick gets turned up. A couple of hard accelerations and it takes a while to recover on the side mount.


Not disagreeing totally with you(diplomatic) I reckon unless the standard turbo gives up, I'd leave it alone. Do the downpipe, exhaust and FMIC if you have the funds. Software to suit and you'll be over 200 and not holding your breath everytime you floor it.

To go with a K04, I would recommend going the whole hog. Fuel pump, injectors 3 inch MAF, turbo inlet pipe, etc and be looking at chipped 8L S3 power, 260+hp.

Fair call, agreed I suppose, just if your getting in their with dump and zorst etc why not go the whole hog and know its bulletproof.

so after much research and loads of help from you guys especially pedro im going to buy a ko4. probably at the end of the month as ive just been to Mt Buller on holz pretty keen on the franken turbo but not sure with the difference on that compared to other ko4s. also going to do full exhaust and fmic. just curious where to get the fmic from as im worried the american sites have ones that invole some playing around with to fit. i already have a cold air intake kit i bought from america which does nothing in power terms but sounds nice and i upgraded the diverter valve. but cheers to everyone for the help

[GtiLER]

with the fmic, i've bought one from America, off ebay. they say it fits, but your gonna have to do a fair bit of cutting to fit it and it could be costly, mine is just sitting at home and i'm just contemplating on what to do, weather to put it in or not. if any of your guys know someone that installs it cheap can you let me know. the quotes so far are around the 600 mark. which is a hole in my pocket.

[04BLACKMAGICGTI]

yer i think its mostly where the intercooler hits the bumper so i found one in the uk for $300 including shipping so might buy it and and borrow my mates grinder if any cutting needs to be done. $600 is a rip, just give it a crack urself i rekon

Try perhaps a water to air setup

frozenboost.com has cheap quality gear.

shorter pressurized intake tract, less piping volume, get a local fabricator to fab up a short amount of pipe,
get some silicone joiners, and have a cold charge all the time, eliminate heatsoak.

[TazzyVR6]

I really need to get mine dyno'd to see what it's making. I love my BMC CDA for cold air induction, sounds fantastic. Also get a powergasket+, you can place your hand straight on the intake manifold after driving, keeps intake temps down and only $50us.
