Can it work

[zacka]

My turbo is broken now
I thout if i can change to one GARRET T28 with courtney manifold..
The problem is, i drive with phase 3, I know that i cant have 1.5 overboost with this bigger turbo..
My question is, how much bar should i have..
My engine is original
should i change the injector?
fuel pump?
Nothing more?

Moin !

Hi Zacka !

You are using our close loop boost control system , so you dont have to care witch turbocharger you use , it will work when the turbocharger is able to boost more then 1.2 bar above 6500RPM !

The turbocharger must have an internal wastegate system with an pressure-actuator !

When you have some problems with the overboost please call me , i can send you another optimized boost controller , no Problem !

thanks or answer..
no it is not a problem with the boost controller, the problem is that my turbo is broken, and i will hange it..

What do you waen: the turbo should the turbo charger be able to boost more then 1.2
Why
But so hight boost and original engine, i dont think thad does work, because i have not change to a steel torque..

What do you think about the engine, it will destroit?

Sorry for my bad english and i hoipe you anderstand

should i mount the 5th injector så the fuel is enought?
should i change he fuel pump
And finaly the fuel injector?

I mabe should visit you in germany with my new turbo and you will check everting and mounted the 5th injector..

Hi Zacka !

You didnt understand me !

I say , that your new turbocharger must be abel to boost minimum 1.2 bar at full load , not less !

The close loop boost control will regulate 1.15 bar at the phase-3 kit , its not depending which turbocharger do you use !

With a KKK K03 ( like VW 1.8 20V ) your never get 1.15 bar at full load , now clear ?

you must adjust your new waste gate to a maximum overboost of 1.5 bar !

There is nothing to do at this application at the fuel system , only install a big pump !

[zacka]

OK thanks
I anderstand now

 

[zacka]

But do you think that the injector or the fule in enought to drive 1.15 bar with the garret T28?
Sorry many question, but i need to now before i by the new turbo

Hi Zacka !

again : The ECU and the fuel injectors at our Phase-3 dont care the Name of your Turbocharger !

It can be a switzer , KKK-Kxy , Garret Tyx , or ....... !

Its a close loop boost control , it will regulate the boost stable with your wastegate until 1.15Bar boost pressure will be measured , for this boost all full load lookup-tables are optimized for this pressure !!!

If you install a K03 from an VW Diesel engine , you will get at maximum a boost of 0.6 Bar , not more , but the boost sontrol cannot help you , your !

When you use a very big bastard charger like KKK-K29 from a DC Actros Truck , you get perhaps also the 1.15 Bar if the waste gate is big enough , but I guess in my experiance , that your engine isnt big enough to produce enough exhaust to drive this turbocharger !


Is now everything clear ?

I think Zacka is worried about if his injector and fuel system is to small for the larger Garret T28BB.

He has an standard C20LET (Calibra Turbo 1995) with the phase3-kit, and will probably use a larger turbo (Garret T28BB) and boost 1.15Bar.

Should he lower the turboboost with the larger turbo if he uses the standard fuel system and phase3 software?
Should he modify the fuel pressure (4.5 Bar today)?

Will he need a 5:th injector-kit?

Does he also need the forged steel connecting rods (schmiede pleuel) and better fuel pump?


Please help him!

Oh Boy Oh Boy Oh Boy !

Please listen carefully again !
--------------------------------------------------------------------------------
Our EDS- phase-3 kit is a close loop boost control system , the regulated boost is 1.15 BAR with the original KKK Calibra Turbo , this one , when fitted with a strong wastegate spring and when the waste-gate valve seat is OK , it can easily supply more than 1.3 bar boost up to 7000RPM , but only with a very high backpressure to the engine !

That means , that he can change the turbocharger to any more or less equal turboladersize that is abel to boost minimum the 1.15 bar + 0.3 bar for reserve , without changing the fuel pressure or installing the 5th injector !!
--------------------------------------------------------------------------------
I also send Zacka the latest V3+ board version with lambda control , so that an engine underfulling damadge because of too less fuel pressure should be impossibel !

--------------------------------------------------------------------------------
Another example : try to heat with a close loop 24° C regulated control system ,your living room at home with a 1000W heater !

- After some time you get 24° with ca. 70% heater power !

- Now exchange the 1000W to a 2000W heater !

- After some time you will get also 24° but with only 35% supply engergy !
--------------------------------------------------------------------------------
With the turbocharger its the same , after getting the 1.15 Bar boost the boost control system will open the waste gate , and the boost pressure is stabilized !

Now clear ??

The Phase-3c chipset is a perfect setup with -4.5 base fuel pressure for 1.15 bar regulated boost up to 7500RPM , the maximum overboost of 1.5 bar at 3500RPM should not be overtaken !!!!
The boost will fall down linear , so that at 5000RPM the 1.15 bar boost are regulated !

But be carefull : The calibra turbo KKK-K16 ( K24 ) is designed with one of the most aggressive exhaust turbines of this series , also the compressor wheel is not one of the bad'est !

Any other turbocharger can effect your low RPM boost response , it can happen , that our car gets slow and tired below 5000RPM and then the hell is going forward ! Did you like that ???

Did you any time had the chance to drive such a turbocharger ??
Please try first , before you wanna spend much money into this projekt !
--------------------------------------------------------------------------------
The only thing that you should do is replace the original GM conrod -bolts to high power types like ARP , or equal !

The most reason for bad engine damadges are broken conrod bolts , even at full not modified LET or XE engines , because the original conrod-skrew is at ALL Opel engines from X1.8XE up to X20XEV , C20XE , C20LET and Z20LET THE SAME PART !!!!!
--------------------------------------------------------------------------------
At least , the best way to keep his engine alive , is to throw out and away the original GM fuel pump , and replace it with the following one :

BOSCH : 0580 254 909 225L/min at 5bar standart working pressure !

This big bastard pump is abel to keep the fuel cool with a high backflow to the tank !
