Guys,
I'm just after stripping and rebuilding the K03 turbo for my project of turbocharging a 1.9D (naturally asp.). I didnt strip the bearing assembly, just both wheel housings for cleaning.
Put the turbo on another 1.9AAZ engine i have here just to try it... going very well, sounds good, spools good and no oil leaks in the compressor housing, however i noticed that there was no movement in the wastegate at all. :cry:
I revved the motor from about 1000 > 2200 and no wastegate operation. I asked someone about it and they said the wastegate will not actuate unless there is a load on the engine (in gear, driving). Surely the turbo will do the same job in relation to engine revs if its in gear or not in gear. Can anyone explain this to me. Before it was fitted, the rod moved fine, and when running, i physically opened the wastegate by hand. Any ideas ? :?
Lastly, i've asked this before, and just want peace of mind about it. I'm keen to start this conversion soon but the only thing stopping me right now is the pump issue. I have a 1.9TD pump with boost enrichment device. Trouble is, both pumps (my 1.9NA incl.) are immobilised and i dont want the trouble of having both pumps stripped by a pro, to have them switched, nor do i want to eliminate it from the pump completely.
The turbo is going on a car that WILL NOT be driven on a regular basis. Very rarely infact. Its just something i've wanted to do for a while since i picked the K03 up at a good price.
Will my 1.9 N/A pump yeild a reasonable increase with the turbo added, matched to shimmed injectors @ 155 / 160 bar. I dont mind a moderate amount of smoke. It will be intercooled also, and a EGT added. In fact, if the TD pump is used, it could create problems with the pipework going from the compressor to the front mounted intercooler (lack of under-bonnet space in that area, and i wanted that pipe straight, not 'dog-legged' around the enrichment device.
any comments about the wastegate or N/a pump, much appreciated.
Thanks again, Regards, DM.
