the waterpump thing will be fixed month end, i have decided to do it myself!! timing seems to be straightfwd...the only thing im not sure about is the tensioner
does the celica 3sgte carry the hydraulic tesioner like the mr2????
problems: i cant launch the car on boost i have to pet number one other wise is no traction at all... thinking bout the mr2 box and axles!!
downtime: none watsoever, this engine is a God sent.....almost 20 yrs old and just basic maintainace oil, plug and filter change on time!!!
Anybody who can provide proof that the term "blow off valve" is not a blanket term and instead it relates SPECIFICALLY to relief valves that vent ONLY to the atmosphere, would be greatly appreciated.
(and people keep asking me why i no longer post on these forums...)
Also AND MORE IMPORTANTLY i would appreciate anybody who can provide evidence that the type of blow off valve that vents to the atmosphere has any SIGNIFICANT advantage over the recirculating type in terms of throttle response and turbo longevity(which are the only reasons the valve exists) in MAP sensor equipped engines.

When the air is sucked in from the turbo the AFM measures the amount of air, sends the measurement to the ecu which would then know how much fuel to add to the air to create the optimum mixture. If you add a bov that releases air to the atmosphere, that would be air that was already meatured by the AFM before, so fuel would already be accommodated for it since it is now released to the atm you would have this extra fuel and no additional air to mix it thus making the mixture rich, drowning out your idle between shifts(thats when the bov releases the air) causing the engine to stumble, poor shifting, poor response and idle surging, fouled plugs, rich mixture, loss of performance.
If you add a vpc, it gets rid of the AFM and adds a map sensor which meters the air after the throttle body by the intake manifold which eliminates this problem. The 3rd gen 3sgte has a map sensor.

Freshly dyno'd at a whopping 820awhp @ 39psi on race gas....ladies and gents I give you Mr. Pat Chin Sue's Celica Alltrac 2.4l 3sgte stroker, built and tuned by Cloak and Dagger Racing!
He also did a 43psi pull but was getting wheelspin.....ON THE FRACKING DYNO!!!
Now go buy a sham-wow and clean up urselves!
alltrac u still didn run shinakuma to show what 3sgte cud do , and shinakuma using a bamboo engine

i might look to install a 3sgte and take out the 4efte jus now in the corolla nah so
this is an unusually serious question from me
