Had last week off work so cracked on fitting the new g25 660 turbo setup.
To recap mocked up on the spare engine.
Started by stripping the 20t hybrid, manifold and downpipe off, oil feed and return removed. Plenty of room with scuttle removed. Turbo first, then manifold, then downpipe out via the top.
Fitting the new setup was reverse of the above. Oil feed in, downpipe in then manifold, external wastegate on then turbo.
External wastegate in situ. Fiddly to fit even though on vbands.
Starter motor heatshield was tight and required a bit of clearance adding with deadblow hammer to clear number 1 exhaust runner. From what ive seen a few people dont refit it, but we do stuff right here.
Oil return fitted. Its tight but adequate clearance off downpipe. Might wrap the last bit of the downpipe for added heatproofing
With that done onto boost hose and coolant lines. Trimmed a 90deg silicone hose and the coolant lines are plug and play.
Next job airfilter/induction. 70mm 45deg silicone hose trimmed and 45deg alloy pipe cut to fit. New ramair filter to suit larger bore
With that done i offered the scuttle panel up. Plenty of room.
Mac valve fitted in preperation for Ecumaster Black. Opted to bolt to the scuttle as no optimal place on engine, and the an line is not very flexible but necessary for heat protection.
Done.
Primed up oil system with coils and injectors unplugged, with turbo oil feed into a bottle to check flow. All good, fitted to turbo and primed turbo with more cranking. Reconnected injectors and coils and hit the switch.
Fired straight up, check for leaks and none. Sounds totally different to the stock manifold/hybrid.
Around 1.5days of work steady away, so not too bad to do.
WIth that done, taxed and out for a test run.
Test drive went well, heat wrap on downpipe smoked like fcuk for a bit but sorted itself out fast. As im on the old map for the hybrid, i cant give it much stick but it spools well and is responsive, seen 7psi around 3500rpm iirc.
In the words of the mrs, it sounds unbelievable. Worth doing for the sound alone.
Ive done 50 or so miles and no issues. Onto ph2 which is ecumaster black install and modified inlet. Aiming for mapping in 6-8 weeks.
