Timer & Controller, Having issues... Options

[Supersprynt]

I am getting conflicting feedback here so i would like to kno what the majority has done, thinks.

I'm putting in the 3sgte - do i NEED a turbo timer and boost controller? I kno some controllers have a timer built it, but are these NECESSARY - or just good ideas to have?

a boost controller is essential in controlling what PSI you are going to run at. i believe that the stock boost pressure is 8 psi which for the 3rd gen 3s-gte (st205) gives you 255hp. If you want more power than that and believe me that engine will take up to 15psi on stock internals. That should give you 325 or more. If you do not have a boost controller then you will never be able to adjust it (boost). The timer is good to have because normally it can control when the turbo activates in a sense. Because I doubt that you want your turbo on a idle. Do you? Also a great thing about some timers is that when you are not riding it hard it will shut off the turbo to let it cool for a few minutes. Because I don't know if you know but under hood temperatures can get very hot. Which in turns heats up turbo oil and starts to break it down. The last thing anyone wants is their turbo to seize up. I think that I have left out somethings. But it is just my opinion. Take it for what you will.

actually, the 2nd gen 3sgte(in the alltrac/gt4) runs at 8 psi

the 3rd gen goes up to 14 i think, depending on some factors. but usually it runs at 12psi. run 2nd and 3rd gen 3sgte's at the same setups(IC, fuel, turbo, etc.), and the 2nd gen should make a little more power due to a higher CR, but as many know, lower CR is much better on a turbo engine which is why the 3rd gen is prefered, it will be more reliable not to mention that they are newer. i believe that the internals on the 2nd and 3rd gen 3sgte's are good to 400hp, which is good enough in my book, unless you have a supra tt or a muscle car.

as for the boost controller, who said you need a new electronic one? try ebay, they are a lot cheaper there or go mechanical(which is what i have).

a turbo timer is a great thing, i still need time to finish installing mine. not only is it a cool thing to have but it really helps with turbo and engine life(even NA cars need to cool down a bit after 1 hour + drives).

btw can anyone confirm the wire colors for me?
i need to know
12v Constant
Ground
12v Ignition
and accessory

The only problem i would have is the alarm that toyota installed in my car wont activate when the car is on, lol, so i will have to manually lock the car.

oh and for the stock tranny issue, there is a guy that has a 400+ hp 3sgte in his 6GC and he is(or was, havent heard anything about him recently) using a stock GT tranny. granted he never really got good traction but the tranny didnt fallt apart.
