My car is done for now, manifold welded and installed, oil pump changed, new SPAL fans installed and running.
The fans sounds louder than my engine now! Sounds like a bloody aircraft is taking off! Tested in the hot afternoon after letting the car cook for awhile, the aircond runs cool when idling under the hot sun now and the aircond cools down pretty quickly as compared to before, like how it used to be when it was 4g18! Fans are important guys, get a SPAL if you're replacing your standard fans.
Also these fans really KICK in, voltage from 13.5v, dips briefly to 12.7v then stabilises around 13.2v with my headlamps, aircond and all running. Now worried my alternator might not be up to the challenge to supply all the current. Next project maybe to install a supercapacitor to stabilize the voltage drop caused by the inrush current of the fans...
Also, PU bushings are awesome! Now the arm doesn't flex as much when the LSD chatters, yet to test the benefits of the 'anti lift' and extra castor feature of the bush, but steering feels pretty spot on during some mild corners. Actuator spring also performing almost just the way I want, giving me 0.6-0.67bar of boost with just the spring, will bring it up to 1.2bar with boost control in the near future.
