Is an hks “gt1” 50mm wastegate still up to par ?

[loveforanescape]

Hello fellow zilvians,

Found a good deal on a old school 50mm Hks wastegate.

Kinda silly I’m considering to even buy this but at a decent price plus me being a sucker for old jdm stuff, I’d pull the trigger.

Have an rb25 and plan on running up towards 320whp - 400whp I on my setup. Since this is a 50mm wastegate would it really lack on the responsiveness?
What other cons would this display on my power goals?
My prioritiy is set on a responsive powerband for drifting.

If any one could point a noob in the right direction I’d greatly appreciate it!

What you should be more concerned with is the application. 50mm is pretty large and is typically only needed on larger displacement engines running lower boost pressures.

I have a 35mm on my ka24 and it does fine o 8 psi of boost. 50mm for me would be overkill. If I was running an LS1 with 8psi I might need a 50mm wg.
