I haven't sent them out yet. I've been doing wastegate research and talking with Sam. Ordering some Turbosmart wastegates soon.

I don't have the specs but i will be going with a larger billet compressor wheel and improved exhaust wheel (most likely Mamba) via Evergreen.

Sounds good. The larger wheel will give you all the boost you need and hopefully the Mamba exhaust wheel is lighter and more efficient resulting in quicker spool up time. All you need is the 18G sized compressor unless you are going really crazy with it.

Whoops, those are exhaust wheels, not compressor wheels. It's early and Monday.

It would be interesting to see what a K16 could do with the 18G sized compressor and the larger exhaust wheel. That might slow it down a touch and give better top end, might be a good option.

If I still have a job come January, I am probably going to pull the trigger on having billet k24 compressor wheels and a k24 turbine wheel milled into these old k16s i got.

otherwise ill just have to settle for maybe clipping the k16 turbine and getting a tune until things get better..if that ever happens.

I found an original set of GT28s in k16 housings for cheap that is kind of tempting..

At a certain point shoving these higher flowing turbine wheels into the little housings will cause its own issues, you'll notice it first with boost control not doing what you want. It's a balancing act, especially if you don't intend or want to build a motor, the limits of the stock motor can be easily reached with the existing compressor/turbine combos...

boost not being able to hit targets due to wonky flow characteristics or hard to modulate at lower rpms?

It seems the stock k24s are good for about 550 WHP with the right supporting mods.

I've been reading about some setups where they used the EMAP pressure to control the wastegates.

I think he's saying the wastegate opening might not be big enough and you would wind up with boost creep.

Wastegates have arrived, just need to change the springs and send everything to Evergreen next week.

Those are good looking pieces.

If you want to get fancy you can run AN lines to them. I made my own for my old 2.7.

That look cool.

The new wastegates and the AN lines are both cool.

got specs on those AN lines/fittings for the WGs? @Celison

how does it connect to the N75 valve (assuming the audi uses one?) which i think they do..

-3AN. Wastegate lines both go into a Y. The unused Y port had a barb fitting that went to the N75. I think it cost me like 50 bucks to make.

EDIT: JK, make that $130.
