Turbo replacement/1z Remap

[philj]

Turbo's gone on the tdi, best get something a bit more "efficient" on there.

Tempted by a VNT, there are loads on ebay, but my only worry is most need a rebuild which leads me think they aren't as strong a normal turbo? Failing that, what would be a good non VNT upgrade that doesn't sacrifice too much spool time?

Does anyone know anywhere that'll remap the 1z for the VNT? It is the later engine with a touch more torque so should support it.

you have to wire in the VNT controller as its a PWM solenoid acticated device

loads of links about this, think K7ERG did it on a 2.5tdi AAT, maby wrong but mentioned in a thread relating to this

Sean.

Any good?

how come the turbo went? was it after you'd upped the power and was this the hybrid I think you had on it and showed me.

My AEL had a VNT fitted when I bought it but require a different ecu and loom wiring. So took a easier option and put a wastegate turbo back on. I have control over it now but as I put a k24 from s2 spool is a bit later than standard. But doesnt really matter as its quick enough for a big diesel.

GT1749v is usually a turbo people put on. Try the tdiclub forum.

Sound, had a look about, as you say the gt1749v seems to be the most obvious choice, with some people opting bigger.

Was more after someone who can sort out a decent custom map for the 1z engine.

Not me with the hybrid? Turbo was always gone to be fair, there was a bit of oil in the pipes when taking the cooler off all those months ago, just forgot about it through the build. One of the new hoses popped off and it was full of oil.

Got a GT2056v vnt here. Not sure on fitment for 1z.

[K7ERG]

I am sure I have blank chips aswell. The chips will need soldered if I remember correctly

k24s have been fitted to 1z's with good results,turbos don't get much cheaper and reliable i wouldn't have thought

GTB2260Vk on my 1Z in my corrado. Mark Malone did the software write for mine including going to vnt. Usable by 2k rpm. Love it and would highly recommend vnt, but won't come near the cost effectiveness of a k24.
