Since my GTB topic is getting a bit offtopic with other related subjects, I figured I might aswell make a project topic with all engine mods listed.
This is the GTB topic I reffered to:
So here it is:
The car, a 147 JTDm 16v from late 2006:
The goal is to reach 240 hp and 450 Nm using a GTB2056v turbo.
- GTB2056v turbo modified to fit
- New stainless downpipe
- Rest of exhaust in stainless 2.5"
- EGR delete
- Modified intake with 80mm MAF and OEM airbox
- Of course a custom map
- Reinforced dual mass flywheel
- Reinforced sports clutch
- Q2 diff

Then I got it remapped at Squadra Tuning to 175 hp and completely shut the EGR.
This is temporary setup, meanwhile I've been busy building all the custom parts around the turbo.
The GTB2056v turbo:
And next to the OEM turbo:
Comparing turbine inlet with the OEM exhaust manifold where it should be mounted to:
Template I've made to make the parts surrounding the turbo:
