Well eah, but .82 turbo is what makes it a bit slower on the spool up, I think. the T70 I have now is .83 AR hot and .70 AR cold (with a T3 flange).
How's your sool up? do you find it responsive?
T70 is OK, but no way in hell it will give you full boost @ 4000 rpm, or 2-3 psi at 2K. I tried, and it isn't happening.
Also the "new" turbo is about 1/2 the weight of the T70.

Now to the hot side...
Need to make it fit into the downpipe I have currently, which means
I need to weld a 3" v-band flange onto the turbo outlet (which is 2.5" currently.
but I already know what needs to be done to make that fit, so I'll do that tomorrow.
After that:
Remove the external waistgate, and block the holes in the manifold and dump pipe.
Take out the T70, bolt on the T3/T04B.
Move the oil lines from one to another and (10 min worth of work)
Hook up the turbo and the intake/charge pipes back into the turbocharger.
No biggie. Will be done over the weekend.

and because I need to rev like crazy to get thepower going, I noticed that my fuel consumption increased quite a bit compared to what it was before.
I used to get around 220 per tank, now it is more like 190. I do run it richer though, when in boost nowdays. So that can be attributed to the fact...

Well, I am too lazy to downshift
I want to step, and go from any RPM.

Yeah I have found that the extra power has made me lazy also, usually I'm in 6th gear at 2-3K rpms and I step on the gas, and LAGGGGGG. All it takes is a quick downshift to 4th or 5th gear to get the juices flowing.
Yeah I made it rich everywhere also. I cruise at 14.7, I have made it fat daddy rich at port opening 6500, richened from 5inHg to 1psi range that was going lean to around 12-13 afr and <11 after 1psi . depending on how cold it is outside I am usually at 10.5 above 50 degrees ambient and normal water temps.

Yep, I'll burn 1/2 tank in an a half hour or less if I am tuning. and after that look at the milage, and it is like 20-30 miles...
Do a 10-12 psi pull at 10.5 AF, you can literally see the needle drop

OK, about 12 hours of work later I took it for a ride.
13 PSI, and Int-X shuts off fuel at 4100 RPM in 2nd gear (not 4rth, or 5th when there is a lot of load)
That is what I am talking about when it comes to spooling.
I did screwed up though, and put the boost controller hose onto the wrong side of the waistgate actuator.
It was at the end, of the day today. I was exhausted, and got confused.
...Going to have to jack the car up again tomorrow, and get to it.
Oh, and I did move the intake into the engine bay.
You should hear the noise this turbo makes
I will make a video, because it will be totally worth it.

Couldn't allow myself to drive to work with unmanageable boost, so I went ahead and jacked the car early in the morning, and moved actuator hose onto to the correct side.
Instantly fixed the boost spike issue. right now it runs at 8 PSI flawlessly.
And i will raze the boost to 11-12 within the next couple of days.
But let me tell ya... This thing is awesome! It pulls so strong from the very beginning, and no need to even give it a whole lot of throttle to get into boost. Blip that pedal a little and you instantly hear "fffssssssssssss" as the turbo spools up and the car takes off...
I must say that I am very, very impressed with my own car.
