t4 turbo, is this kit any good ?

[houston]

Most things we buy nowadays are made in china arent they?? they all have to be made to a decent quality for people to be able to sell them dont they.. you cant sell something that is going to blow when you push it to the quoted figures they have provided? 

No steer clear imo

Have you have tried and tested one?

We have tried and tested many cheap turbos from ebay, xs-power ssautochrome and all made good power and lasted the duration. One was a T34/s5 running at 508bhp@1.7bar another 1.5bar 470bhp,  T3/04e 404bhp@1.7bar(£140 turbo from ebay)  k04-001 240bhp.

Its down to how they are tuned and heat generation, and even if it blows in the 1st year its only going to cost £140 for a new one, and not £1k+ for a oem.

Done right they are worth the money IMHO.

agree, if people are buying cheap then its usually fitted and setup cheap, how they get the bad rep.

but if it blows your prob gonna be lookin at more than 140 when it sends its internals into your engine

umm i seen that nick has just done a ko4s so im stuck
also i read the t3 and t4 turbos dont last long on the 1.8t engines!!
dont you have to run a atmospheric dv with the t4 aswell??

Nick did a ko4-001 which is a direct bolt on to the standard manifold. As Nick said you can overfuel and use the fuel as a coolant.

DV is your choice, you can continue to use a recirculating system or atmospheric.

007p dv needed not BOV as the induction system metres the air in the system and the ecu cannot take in to account the lost air from a BOV.
Cheap K04-001 was a direct bolt on, the only issue was poor settings on the actuator, which we had to setup correct before mapping.  This was fitted to a customers car 2 year back and I still going strong now.

[tech1889]

have you got a k04-001 graph ??

[golf-sib]

so the 2year old k04-001 was a chines copy and is doing that well?

What's your views on the oil cooler as it comes with the kit, a worthless mod or worth it?

[RTechUK]

have you got a k04-001 graph ??

Only my OEM k04-001 graphs not the cheap turbo.



@golf-sib
I have not played around with oil coolers its not what we do.

[Dave_IOW]

Just what i wanted to hear, better get the KO3s back off then 

[porter_89]

So the new turbo is still direct fit and has power if ko4-023?? I am being taking into doing this if all goes well Nick lol

My stock oem k04-001 is being pushed hard and making 262bhp with decat, fmic, ported exhaust manifold, its been running spot on since septmber 2010. But the way its not the way I would map a customers car, this is why I have produced the k04s (direct bolt on for kkk all ko3/ko3s) The k04s has a bigger comp wheel, comp housing and back plate to allow to turbo to flow more at the top end per shaft rotation, the stock 001 will easy produce  and flow 330lbft at around 3200rpm we what we have donw its lose a bit of low down spooling and cap the torque to 280-290lbft then aim for 270bhp at the top and with out pushing the turbo too hard on customers cars.

So far I am at 268.5bhp with the k04s without any mapping work to the software, I also want to test it with a 3" maf and mapping I think to go any more at the top end I will need a Forge actuator to hold the wastegate closed a bit more as its cracking open under its own pressure.

On the road the k04s is mental, and will give the K04-023 a good run for its money.

I am going to upload the graph from my phone to facebook account in 30mins when I get home, so it you want to see it just add me Niki Gower to the friends list.
If some can copy and paste it to here that would be great.


ps
Remember I am runnig water injection for cylinder cooling so a lot of egt testing would be needed before customers start to use it at 270+bhp wit out water injection

to make a k04s, would you need a k04-001 or could you do it to a k03/s as well? also would the vr6 clutch keep up with this power?
