It would be easier to do 2.5" instead of 3". The 3" only comes in bends that are 4.5" radius and larger IIRC from what I found. 2.5" pipe comes in bends that are closer to 3" radius...again IIRC, it has been a bit since I was into it. Whatever you do, please Vband it. I can take off my down pipe in less than 5 minutes if it isn't hot. Getting it back on doesn't take much either.

Could you make a size comparison for me? Is it smaller then a t3? Or larher. Or maybe take a picture next to something?

What are you talking about here?
If it is the turbo, the physical outside size of it is about like the AAZ K14, it is smaller than the t3 and K24. I had a pic with my hand on it, but I have decent sized hands.
If you are talking the downpipe, then it is way bigger than the T3 pipe

That answered my question I was just wondering the physical size. It makes seems to make very good power for the size.

It is all about design. It is way bigger than the t3 or k24. The exhaust housing is pretty much 2x as big as the T3.

These Holsets are also 20-30 years newer technology than those ancient laggy low-powered T3/K24 turbos and neither of those live for long at 30+ psi from experience

so on a side note i have been having a little issue ever since i had the car running. right now it seems like a little slack of power even when i have 20psi. not really sure what could cause the lack of power. here is a video of what happens if you come onto it if its the first couples times since you started driving. it happends if it is warm or cold.

Something isn't right.
What have you checked already?
I would start with the shaft play in the turbo as that is easy. Tons of other stuff to check, but I will wait for your list of what you have done.

This has happend with 3 different turbos. No fuel leaks runs fine after it does that

so I smoke tested my intake today to see that my wastegate seemed to be leaking. does anyone know how that would affect power/boost? I currently make about 20psi but it should be more then that and the car seems way under powered.
its leaking from where my finger is. (this is not the turbo on the car)
thanks for the help guys

Is the wastegate leaking out of that small hole on the bottom of the can, or where it meets the turbine housing? isn't that where the other end of the diaphragm bleeds to atmosphere so it doesn't get hung up? If so you might have a leaking diaphragm, which means eventually the diaphragm will have a larger hole in it and the wastegate will cease to function.
As far as the missing and grey/white smoke, I think you might have a combination of leaking turbine shaft seal and either bad injector or head gasket. Are you losing any coolant over time with no evidence of leakage? I'd try getting your injectors tested before taking off the head and checking for a bad gasket. Hope it isn't a prechamber.

Head gasket and prechambers were done probably a week before that video was taken. The injectors were rebuilt and balanced by Giles. For the turbo I think I am going to fix my k24 waste gate and run that until I have the funds for a larger turbo

K-14 left, Holset HE200 on right.
The efficiencies have improved substantially in 20 years

would the he211w be bigger then that?
also what do you guys think of the HE200wg? would it be to big??
thanks for the help guys
the car is coming off the road tonight (hopefully) and i am going to be sending the pump to giles to get it tuned for about 35psi and i am going to fix a few things and get a turbo to put onto it and put my custom ground dr diesel cam in it. hopefully it all goes well and i can make almost 200whp! fingers crossed all the parts start to come together!!

So I finally got tired of used turbos. I ordered a he200wg from Alcaid. I can't wait for it to get here. Is there any suggestions that I should do before I put it on?
What exhaust manifold is best? The one I have seen on ebay go straight out. Not sure if that would make a tight fit between the turbo and the firewall.
What pyrometer do you guys run? Also what is the danger zone for heat on these engines?
