Changed the wiring harness to my original as half the wires were hacked to hell. Originally she was dumping water into the crankcase. HG!!!! For those who got back to me on my first thread on here. i.e. BustedKnuckles and one or two others. Thanx.
Anyhow had no com. between the engine and the computer I then realized other things had to be swapped as well. Oil Press sending unit, t-stat housing, knock sensors, etc.
Done all and complete. Got some killer power out of her finally. Cooling system has a couple of qwirks gettn em resolved but she runs and runs well.
My issue is all boost at this point. I have replaced vacuum lines in and out and top to bottom. Everything is tight with all new gaskets on the top end. Hours spent looking high and low and double checking every connection I have made every inch of my baby. Im good at that.
I have found when driving her around that I am not creating maximum boost for a stock CT26 saddly enough. I get on her she spools she creates a bit of boost, doesnt display on the gauge. Only-4 to 0 psi? Then a bit of blow off. I want to know what if not a loose connection where this issue could be? Getting her straight and running like she is supposed to be is more important than my job at this point. I have spent a grip of time and money on her and the body needs the love next but I gotta get the engine straight first. Any help would be greatly appreciated and I thank all of on here who have taken time to point me in all the different directions I have been pointed on making my Supra all she can be. I have had issue after issue thread after thread and all of you out there have been dead on with the tips you have givin me. THANX!!!  |
I read your other thread. If the gauge is reading properly then there must be something you over looked. It should read -19 to -22 lbs. while idling. I'm sure you've checked but the most commonly missed vacuum is that to the power steering pump. It runs all the way from the front side of the intake manifold, across the front of the engine, into the pump, and out to the intake boot. Also, are you recirculating your BOV?
