Would I need to rewire my EBC or just leaving it wold be okay?

nope... you wont be boosting @ idle because the actuator is only open when the engine is in vacumm mode, as soon as load is put on the engine, it disappears. From my experience, with the EBC, the computer controls when you should have boost, and that seems like after the engine has run out of power. So its more of like a variable thing. With the bypass setup, power is added from the start so it feels like a bigger motor instead of having a huge boost kick later on in the rpm range.

Again about the instant boost, lets say that you floor it. You wont be boosting @ idle or making 4psi instantly from 1k rpm either. The supercharger is belt driven so it still has to spin up to make that 4psi. Difference is with ebc, sometimes you dont get full boost/get max boost for a second. Bypass=actuator is fully closed and at WOT the engine is pressurized and just keeps on climbing until 4psi or when you let off the throttle and there is no load.

Ron, from my understanding, the EBC reprograms the system once used for the stock N/A (acoustic valve thing) and instead controls the actuator to release boost. Since goign from the bottom barb straight to the actuator having it regulated mechanically by vacumm, the system is no longer used. The original setup included caps for the unused ports under the plastic cover and said to zip tie the black bottom canister hoses to be left unused. I just left the hoses where they were and plugged them into each other which made a nice clean loop. Im sure that the ebc still actuates some valves and such, but since it is all bypassed, it wont harm/have any use. I talked to Jim and Paul (Vampire) about it and they both said to just leave it in. Acutally Jim said he never installed it and has been running a stock auto tranny @ 300hp+ on his car for almost 3 years. Paul is a 5sp which is a bonus since as soon as he shifts, boost is vented from the lack of load on the motor. Auto on the other hand never lets off the accelerator leading to boost in between shifts which adds additional stress to the auto tranny.

You're right. With any perfomance increase there is inherent risk to the drivetrain and you can be sure the "stock" life of your engine has been lowered. If you're not comfortable, I wouldn't do it. There really isn't an OEM stock FWD tranny that can take the abuse that a good RWD tranny can take. If you do decide to try this, make sure you have always maintained your tranny with regular flushes and filter changes. Not the Toyota recommended 30K miles stuff but more like every 15K miles. You should also have a good tranny cooler on there and if you're really into it, a valve body modification. Too bad a built tranny is soo expensive. IPT wants something like 3 grand but that baby will take a lot of abuse.

I wouldnt do it unless you know what your doing and got money to back that Shiz up.... Id like the idea to do it.. Faster car.. But doesnt seem too safe..

Good points Castro. The ECU actually doesn't even know if the EBC is there or not so it doesn't matter if you leave it on or remove it. The ECU still thinks the ACIS system is there and that system had no closed loop feedback that I know of.

The auto tranny shifts relatively slowly. That's why grandpa and grandma like the smooth acceleration of their Camry and Solara. Unfortunately, this generates more heat as the clutches engage. Think or revving you manual tranny car a little more and feathering the clutch a little too much. The clutch heats up more. A good tranny cooler will help a lot in this and if you really are into it, a valve body mod will make your shifts quicker and more positive feeling.

dats, just skip the ebc and from the bottom port of the s/c, route that hose right up to the actuator/wategate. It should be hooked up the way it says in the original TRD hose diagram. with the ebc/supplement packet revision hosing it will hardly give you boost. I have an auto and use the original setup bypassing the ebc and its great. I race my brothers car and lets just say that it makes the difference between me losing vs. now flying past him easily.

sorry to bring up an old post, but i was looking at my supplement manual and i was confused....it looks like the barb by the throttle body goes to the vacuum canister and then to the vsv...the acuator just runs to the pcv.....what exactly to i disconnect and bypass?

[shocar4]

anyone?

[Wang2k]

man u r killin me! lol

ok the point is to run vacuum to the bypass valve on the s/c, so that the valve will open at idle and close completely while in boost. It doesnt really matter how you do it. I have the little barb(the one you have to remove the throttle body to get to) capped off and one of the barbs on top hooked to the bypass, and the other one connected to egr i think(my car is still in the paint shop)

so the vsv's that the ebc were working are disconnected and have no lines on them.

[Wang2k]

also.



i thought I was a post whore. u got me beat

[SC V6]

I don't even have my EBC hooked up

[shocar4]

okay now i am really confused! all the abbreviations get me screwed up....i found a post like two weeks ago and it made sense. now i can't find it! all i know is that you plugged some ports and ran a line straight from the barb by the tb to the bypass acuator.....right??? what about the pcv that is connected to the bypass acuator? sorry for my ignorance!
