what did you do to your non-Protege today?

that's a pretty bold statement.

lol that picture is way bigger than it looked on my phone

fixed cylinder 1 misfire issue, found a coolant leak, figured out why the wastegate isn't opening. fixing the last two and some exhaust leaks tomorrow and then going to do burnouts.

[atomicEGT]

fixed the coolant leak, broken turbine outlet stud, and some exhaust leaks, as well as adding a vacuum block for a solid wastegate signal.

[concealer404]

Wastegate shouldn't see vacuum. If you're referencing wastegate post throttle body, you're doing it wrong.

[atomicEGT]

oh, I am dumb then. why not?

[atomicEGT]

not like it matters, I went to go actually drive the car today and see what new bugs I need to fix, and it doesn't ****ing start.

I'm going to set myself on fire.

I'm pretty sure you'd regret that in the morning. I'd advise you to rethink the self-immolation strategy.

thats total & utter bull****!!!!

where did you pull this **** info from??

[atomicEGT]

I have legit never heard that before. SR gets wastegate signal from a nipple just under the TB, and I used one from the intake manifold when I had my EGT turbo, no real issues (after I went to an external gate anyway, since IHI internals are the worst **** ever)

[FE3-323]

the most accurate signal to the wastegate should come from the intake manifold. (representing the pressure the valves are seeing)
coming off the turbo per instance shows you the outlet pressure, & doesn't reflect what the motor is actually getting after pressure losses/etc. (not to mention the vacuum level is improper)

vacuum actually assists the wastegate in sealing---- so tell me how thats a bad or improper idea????

OEM keeps the length short for the sake of saving manufacturing costs/ materials & because its easy. not because its accurate.

[atomicEGT]

look all I care about is that the wastegate opens at 10-12psi in first and 7 in second+

turns out the fuel pump was dead. car runs again, overheated before I made it down the street. lololol **** my life

U srs? This has been debated and explained for.... years. Decade? Long time. Vacuum to gates isn't great. The worst part is the "infinite boost" situation your turbo can see as you're inadvertently manipulating the "signal" to the wastegate with your right foot.

The correct location is between intercooler and throttle body. You get the response of referencing from compressor(ish) and account for pressure drop across core.
