Delta III 1.9 TT

Anyone has some information on the Lancia Delta 1.9 TwinTurbo?

Hello guys,

comparing both, the lancia 1.9 mjet 16v twinTurbo and the Alfa 1.9 mjet 16v on the Alfa GT.

How is the intake system on the lancia build, could it fit on the GT - does the twin turbo fit the alfa head? looks like it comes with integrated manifold.

regards

You're proberbly better of using a gtb unit instead.

yeah gtb 2056 on the other side .... could your tuner of choice offer a kit or something? I've driven the delta and i'm seriously impressed how lagfree the whole thing operates... not shure the gtb would be that smooth...would it?

How will you convince your ECU to drive two separate vacuum regulators?

Hello, are you shure it uses two regulators? i thought the low end turbo would be wastgate operated..(open wastegate to spool 2nd turbo) ? i have no not seen that turbo in person jet so it's just guessing on my side.

thanks for the pictures, this looks indeed like wastegate operated turbos the levers of those actuators go to the exhaust housing....if you look how they are positioned -in axis... could indicate wastegate not variable vaned turbos.

question is what part ecu controlls... afaik pressure regulators on such turbos are pressure and not vaccuun regulated....


any one knows for certain?
chiptuners maybe?


EDIT: nah...just realized the LP-Turbo is shut down on high engine speeds... so two regulators needed.... damn...

I am sure you will be equally impressed if you drive a GTB equipped JTD with proper tune.
That GTB gives as much low end torque as the driveline could handle.

Hello joel,

will see most likely getting the 16V remapped by stephan (squadra) anyway (egr closing...) so will be in the netherlands - would be interessted to see your car in person....

however, a warning on my side: my (remapped) 8V destroyed the 6 speed stock diff a few weeks ago ( nasty vibrations off pedal)... so dont push it to far without a Q2 diff or anything simmlar....

They are both waste gate operated as far as I know but they also have butterfly valves in the intake and exhaust and I am not sure what the method of operation is for them.
