Some valid points, learnt something new about the powersteering stuff..... Only comment i have with regards to the corolla mani/std throttle body is that theres no response or major pull from the engine below 3k (boring tootling around town) after 3k its where it comes alive this combo has time and time again helped when overtaking/getting past the twats on the motorway. in 5th from 60 mph @ 3k - 100 mph is where the acceleration is really at Also with regards to the powersteering pipes, one of the ports on the throttle body continuously suck air when the pipes are disconnected leading to a high idle ~2k all the time till blocked off. And the other one didnt seem to do anything? ill get someone to sit in the car and move the steering next time to test further. iirc when blocked off i had no driveability issues at all when going out for a drive so there shouldnt be a major problem.....could always put that one pipe on the extra vac outlets on the FTE mani to give it suction?? amjad, alot needs to be blocked off the FTE mani the only real problematic ones being the ICV and the temp sensor on the front.
