hi guys,new to here i have a 1.9 d turbo s and wondered if i could put what would essentially a bigger turbo in it to give it more oooomph:blink1:
out of curiosity what exactly will the pump help with ?
i was thinking about doing that does it change the fuel comsumption much ?
not sure on how the dump valve will preserve the turbo ? they are there to get rid of excess pressure when the butterfly plate in the throttle body closes. as diesel generally dont have throttles in the same way as petrols, theyre as some "throttles" in some engines but generally not, then there is no increase in pressure for the dump valve to work with.
how hard to fit, find a boost pipe and plumb it in using a vac line to operate it
Yeah your correct. All mechanically timed bud, not an ECU in sight! Minus the airbag.
If it is boosting at 17psi, the previous owner has performed the stage 1 already. If you can still get into contact with him, ask him. Next step would be to find a Bosch VE pump. Which is far more stable and is much more tunable.
Can I but in and ask If you know much about the ACdelco fuel pump,
I bought 1 ready to put in my car for future necesity. It is a genuine pump for the VS commodore but they claim it has better flow rate than the "genuine,genuine". (if that makes sense) Basically it looks Identical to the genuine and they call it an upgrade performance pump!!!
Couldn't find any flow rates or KPA specs.
(It would bean upgrade if your old one is stuffed

basically i think it preserves it coz it lets the presure out instead of being trapped and the presure has no where to go if you get me
i beg to differ...i have a lucas pump and i have turned the max fuel a full turn,the boost compensater is standard setting.my kkk turbo acuator is turned all the way in and back 1 turn.i have a stainless steel exhaust with no cat or middle box,just a cobra back box and i am running just over 22psi with only grey smoke:bigsmile: sounds pucka spooling over.the current pump which is more then likely a lucus fuel pump, is very... Crap. Basically. It hasn't got stronger internals, you can only increase fuelling a little bit. With a bosch pump, it's complete opposite, it's very tunable, very very strong and very relaible. Plus if you do bolt on a larger turbo, it will help with the fuel delivery better. More fuel more power basically.
