Hmm seems strange that it uses factory oil / water lines and down pipe off K03s and yet they changed the tip size LOL cheers rich :afro:

K04-001 is a 100% direct fit from your K03s and the Forge k03s tip will fit spot on :wink:

The turbine internals are bigger, the comp wheel is k03 size but with a new blade confiuration, put the k04-023 cold side on the 001 and you have enough to flow for 299bhp.

Other mods needed to get the 001 on full song are, 386cc BAM/AMK injectors @3bar, then port the collector and runner number 3 on your exhaust manifold.

try searching google, im sure the compressor wheel in the k04-001 is slightly smaller than the k03s   :drool: not 100% sure though
it does have  a larger turbine wheel though..
the reason the oil/coolant/downpipe ect are the same it because it shares the same turbine housing cast as the k03 and the chra housing is the same for the k03 and k04. it starts do differ when you alter the exhaust housing for one like the k04-023 which is for longitudianal cars like the passat.. to fit one to the golf the S3/TT 225 exhaust manifold, oil/coolant lines and downpipe would be needed.
im not sure exactly what tip size is needed for the k04-001.. i would have thought you could get an aftermarket k03s tip to fit to be honest.

comp wheel same height size and back plate is same as k03 sosmaller than k03s, but the 001 wheel wont fit the k03 comp housing the TIP size works out to be the same as a k03s..lol

The K04-001 is the most confusing turbo for the 1.8T, no one knows why it was built and what for? and its hard to get exact specs unless you take one apart like I did,, but what I can say its the most fun turbo out there for the 1.8Ts. 300lbft at close on to3000rpm..

I will find out for you on price, (might be worth hanging on until so of the k03-023 hybrids are up and running, I have a customers AUM booked on the 7th Jan to see what the 03-023 hybrid will push from a map.

I have my k04-001 (just turbo) run 13.9s at santa pod which is quicker than all the strong stage2 LCRs and S3 K04 engines.  I started of tuning the 001 to 262bhp 290lbft, then went mad for a while and made 270bhp 334lbft with big boost, then wanted more flow so bolted the k04-023 cold side to it and made 299bhp.    

Now got a 450bhp stage-3 .63 T304e going on the beast with multi port 100hp nos and WMI... :grin:

I would go for uprated rods if you want big torque numbers. I snapped my number 1 rod with the 001 at 290lbft, but was it the oil pump chain fail,  fatigue from a rod with 156k or peak cylinder pressure from 290lbft?  Best to be safe the sorry, but saying that you can get an AUM/AUQ engine with less the 70k for £300-350.

Its the fitting, new head gasket set, cambelt kit, piston rings, tensioner, pulley, ARP head bolts, waterpump, oil pump that might aswell be done at the same time!

Some of the above are essential too..

Been looking into this there are few different 001 out there with 2-3 different size intakes rangeing from 43,50 and 55mm. 43mm same as ko3s other 2 sizes need fine relevant tip to fit which may turn out to be ball ache. Would it be bigger intake with larger blades more power from turbo??

Still deciding how far to go with it as will hopefully only be on for just over a year..

Get the T304E turbo Dave, you know it makes sense, you will get your 300bhp you are after on stock internals, and if you do ever upgrade internals it still has power to take you further  :wink:

Ive already got a Garrett sat in my living room  :grin:

Capable of 300 at the wheels of a 4wd pulsar, so with less loss, might see 320.. LSD and 4wd - less, that should be enough..

Greed, its a powerful thing.

So how many months with the garrett on till you start looking for a construction truck turbo and a broken 4mo for the 4wd  :grin: :grin: :grin:

4mo for 4wd would be great but is a hell of a long way off tbh...
