How is the turbo working out, had any problems to solve? What did the turbo come off of?

that Turbo is a Detroit Diesel tv8101,compressor is the correct size but turbine side is too big and it starts to spool 4000 rpm I need to find a smaller turbine but it is hard to find from Finland.
engine is 402 bbc 702 ovalport heads 750 db carb and edis wasted spark ignition cam is comp cams xe 284
I will change the cam shaft something like this http://www.summitracing.com/parts/sum-1302
This is a fun project to which I have collected all of the left over parts

Are you changing camshaft to increase the LSA from 110° to 114° for the turbo? The Summit cams seems to be a bit milder.

that summit cam is pretty small but it probably works pretty well with turbo
I use e85 if the compression gets too high

I took the cylinder heads off and measured the quench, static compression is 9,2 and with that summit cam dynamic compression is 8,3.
this may be a small problem with pump gas and boost, but I have two bosch 044 fuel pumps and two 12mm fuel lines, so I can use e85 with no problems

Do you have those Bosch fuel pump configured in a parallel or series combination?

I figured they would be in parallel, but when I Googled it you can run
them in series if you want to boost the pressure. Then I wasn't so sure.

small update again
I've been a little busy, so I have not had time to write here
I broke my crankshaft, camshaft, connecting rods, oil pump, transmission, converter and turbo
a little welding, grinding and here is my new combo
402 bbc
702 ovalport heads ported
xe 294 ft cam
team g intake+demon 850carb
2x60mm turbos
wastedspark ignition megasquirt controller
th400 tranS
8,5 10 bolt 3,08-1 gears
the car is really powerful, but I have had trouble with the carburetor, e85 really need a lot of flow so I've been looking for the right tune by drilling mainwells,angle channels and boosters
I also have a vent tube extenssion. but there is still a lean spots
here is some pics

that truck would even be impressive over here on this side of the pond, so I,m sure it gets a few looks over on your side where larger displacement turbo v8 engines are less common

IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

Any idea where the problems started and what caused it?

bad crankshaft broke two bearings and the oil pressure dropped down to idle, it broke the turbo, cam shaft and oil pump.
the old converter broked and broke the transmission front pump
I found the crankshaft, bearings, rods and th 400 transmission from Sweden
the cam shaft found in the shelf, it is not right for this engine, but works surprisingly well
I fixed the transmission, I did the dual feet mod, 34 element sprag and installed the aluminum pistons
I bought turbos from China and they are working well
I've tried 0.5-1 bar boost and pistons looked like new
the car is a flying coffin I need to make changes to the suspension that it handdle the new engine
