stock waste gate limits

[conlyn]

well, i'm soon thinking of getting a 3bar/chip/50# for my truck as my next upgrade, and i was wondering what the max psi. i could run a stock wastegate at?

mine is a big ugly/dirty/oily mess and i was thinking about just going with a stock-type replacement due to it costing like 1/3 of a real wastegate and being (i assume) easier to install...

my motor isn't exactly a fresh 20k mile ty motor so i don't plan on running over 19 psi unless i take the big jump and go alky in it.

well, in the money i'll spend... should i just save up and buy a mini gate/boost controller?
and if so please direct me to some decent cheap ones.

What exactly do you want to do a stock-type replacement of? Just the wastegate? Or the entire turbine housing? Are you having problems holding boost?

just the wastegate unit it's self, mccoy sells a replacement unit....
and as i said, my wastegate looks like the most abused part under my hood.

well, it holds boost, but will it be able to hold enough?

Re: stock waste gate limits

The stock turbo will start falling on its face at 20psi; the stock wastegate will hold that.

For external wastegates, unfortunately there aren't any "cheap" ones; an ITS Minigate will be fine for what you're doing, and that'll still set you back $250. If you are keeping your stock turbo, and your stock wastegate was sticky or leaked or you were just sick of adjusting and messing with it, you might want to look at an external mounted on the xover pipe, but for right now, although its dirty, if it ain't broke, don't fix it. Clean it up, it'll hold 20.

If a new turbo is in your future, definitely get an external; either opt for a "kit" (3" downpipe and wastegate on the DP), or mount an external on the xover for sure.

That wastegate is fine......functions as good as any I've seen. Get the chip/map and leave the WG alone. Like was said above, if a larger turbo or free'r flowing exhaust is in your future, then consider external. But as solid as I had that thing tuned to hold boost, I wouldn't touch the wastegate.
