Which will bend and fail. Never suggest a flat bracket unless it's made out of 1/4" flat steel.

And please enlighten me on how it's so much easier when the guy is already building his own manifold? Not trying to be a dick but I don't find your comparison to be accurate.
If you're building everything from scratch sure. Hell go with a vband while you're at it. However if you already have everything built and an internal wastegate works just fine, adding an external wastegate will be a lot extra work.

I for my comparison i was going with the idea of using a fuel pressure riser to adjust your fuel in boost that you could easily do by tunning megasquirt. I guess it was just the whole thing of overdoing it for no reason.


As far as the bracket bending issue goes. A properly cut 1/8" thick steel bracket will do just fine. Hell go with a 3/16" while you're at it if you want the security.

lol I know what you meant, that's why I didn't want to show my turbo, it's not cool v-band. Just my exhaust and wastegate are v-band. The next one will be all v-band, I love those things, I have been kinda tossing the idea around to use them on my charge pipes as well instead of silicone couplers.

Well you want some silicone couplers to allow movement unless you plan on V mounting an intercooler that is free to move with the engine.

One off the turbo and one at the throttle body was my thinking, maybe it needs more flexibility than that

Lol, you guys are funny arguing about something that entirely misses the point. External wastegates are expensive. The entire point of building my own manifold and using an $80 turbo is that this build is super cheap. If I had the money for an external wastegate and a nice v-band turbo setup, I would just pay Tim the extra money for one of his sexy absurdflow manifolds insead of building it myself. As for the wastegate actuator, I'll either be using box tubing or welding some threaded bosses to the cold side housing.

PM me. I have to get ready for school (machinist), but I read a few posts here.

I have an idea where you're at. Believe me.

I rotated my Super16G compressor housing, therefore, had to make new mounting brackets for the wastegate actuator. Originally, it wasn't done right. More about that later.

Here's my schedule 40 turbo manifold, as well. Equal length, 38.75" primaries, all within .25" tolerance. True, it probably exceeds 40 lbs, but it's not going to crack any time soon, and I can stand (and jump) on it.

Fried timing belt?

Shoulda done a top mount with the turbo sticking out through a hole in the hood.

I'd like to see what you have working. I was doing a search on WRX Turbos (13bs or the like), and first thing I see is you're in Albuquerque too. Hit me up when you get a chance, I'd love to see what you have set right now.

I'm contemplating a log type right now with a wrx turbo, so this thread was useful. Thanks!

Sooo, is Weirtech the only place to get 1.6 exhaust mani flanges at the moment? I don't see anything else noted here, can't find anything online, and it doesn't look like elesjuan got any made.

Good bump. I'd eventually like to pick up a 1.8 flange. I'd be nice if we could get something thicker than the 3/8" mild that Weir has on their site.

weirtech looks the cheapest, i need to order one meow for a 1.6. JGS also has them for 7x.0 buxs
JGS Precision Turbo Wastegates and Bypass Valves
i think im going to go with weirtech unless someones got something better.
