t4 turbo, is this kit any good ?

[lord14]

the wastegate (external replaces the standard one on  a ko3 , or whatever turbo you have , depends what boost you are running if you running over 15psi of boost you need a 15psi spring . and the hose from the n75 which normally goes to teh standard wastegate goes to the side of the external and them leave the top for atmosphere . but a electronic boost controller is alot better to use rather than the n75 valve

Thats what I thought as I see a manifold with the screamer split on it and a little nozzle where the 3mm vacuum piping goes like it does to the actuator.

n75 is not bad but it really needs the aid of the MBC especially when you are pushing your internals to the limit, last thing you want is overboosting or spikes with silly power. It also is handy to switch between silly power and casual driving power.

How you coping with that screamer, I've heard mixed responses with them due to noise, obviously the MOT tester decides if he thinks its to noisy same with exhausts and can fail you, mr plod if he deems it too noisy can annoy you but its down to the individual and what they deem as "too noisy".

I heard some people lengthen the pipe and make it bendy, others have put a silencer on...

Also with the eMBC, when on the lower settings, is it considerably less noisy or really no different.

Yep the TIP needs discussing, think fabricating it with mild steel is what I will be doing. But I think this project will kick start in a few months as I'm moving into the house I just bought. Already a huge to do list for the house let alone the car

screamer is loud but only when your giving it alot . normal driving you cant hear it . i tried a mbc and it was spiking and would never work , best bets to take all the pipes off the n75 and use a exlextronic bosot controller . lower boost the louder it screams

my MBC only leaves two pipes blocked off and only leaves the terminal on the TIP. As I have some diagrams somewhere where you can set up the MBC in two ways, on way where you override the n75 and control the boost with the mbc or you can set it up in parallel and eliminate the spike. Is the eMBC kits similar as I haven't really looked at them?

Also where are good places to exhuast the screamer pipe? You've obviously use the wing but your turbo is close to the wing which gives you that advantage.

[lord14]

you can either have it straight to the floor which is easier on those manifolds . or you can connect it into the dowpipe

dave sorry to hi jack the thread when you come to selling the actuator give me a pm i might be interested will it work on ko4?? thats the road im going down i hate the sound of screamer pipe soiunds like a bag of spanners in the engine

cheers

also the t4 turbo is there more power going this way to the ko4 tuebo

[golf-sib]

t4 is superior

Pretty sure ko4 runs out off puff around 265bhp.

[porter_89]

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??

[RTechUK]

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.
