Its basically Td05h-18g(Big Comp housing with 3" intake)>T518z(Compact compressor housing 18g)>T517z. It really just depends on what you want to do with the car....Im pretty sure all of these turbos are Still T2 framed 8cm Exhaust housing If I remember correctly though.
To me the Benefits of the greddy turbos are reliability. With those turbos you have just one less leak to worry about and less stuff cluttering the engine bay. My perfect simple setup would be one of those greddy turbos (doesn't really matter which one), Gtir manifold with external gate and E85. The Tq numbers these turbos make on our motors is crazy
I actually bought a used 18G from a forum member after reading all your post about this turbo. I have not installed it yet, but I am planing on using it on a bone stock VE. I see you had a DE+S4 and this turbo from your previous posts, and it was putting to shame a couple of V8 cars on the highway.
Do you have any experience with this turbo + VE? Any suggestions to make the install go smooth?
Also my turbo has up and down play, no in and out and it doesn't hit the housing. Should I rebuild it anyway?
Set up
Stock VE (fresh hone,new rings, ACl bearings)
W11 Manifold (plan to fly cut the bottom flange to raise the turbo for intake clearance)
Greddy 18G , (has a 8cm ex housing)
3" - j-pipe, Dp, no cat, full exhaust
550CC injectors
AEM 320 E85 ready pump
Tuning currently with Calum RT + wideband
Thanks in advance
