Injectors are stock from a 2.0 NA Opel engine.
They were test fitted with a modified fuel rail then removed. With this upgrade I can swap them to any bigger size injectors to suit the power needs in the future.
They will be put pack before when ECU tuning starts, for now I'm running the factory ones.

There is no data for them online, neither in the service manuals nor in the shop catalogues.
But since they struggle keeping a good AFR even with 80 hp, I would estimate around 170-180 cc at a flow rate bigger than 80%. They are really small.

-Turbo mounts done.
-Air intake and BOV placement done.
-Turboback exhaust also done (catless stainless steel with a single Borla muffler)
- Much fiddling around has been made in order to obtain the best positioning for hoses, fittings etc.
The car leaves tomorrow for the ECU tune shop for installation and setup. Hopefully nothing blows up on the dyno and we reach the desired target

Got around to downloading some 
BOV was rotated after taking the pics.
The underside of the exhaust is nothing special, just a 50 mm straight pipe.
I didn't get a chance to make a video for the new exhaust sound because my phone battery was dead at the moment, but I'll make some videos after tuning and post them on YT as usual.

I read you have calculated that safe boost is 4-5psi do you not worry about motor issues ? More interesting is it still complying with emission standards like CO/CO2/HC have you test those ? as I seen removed first cat don't know only why if can be done nicely with first and second cat
I've found another matiz from poland running 15 psi for more than 50000 km on stock engine and gearbox.
Low compression ratio from factory helps achieve that. It has 9.3:1.
Both cats were deleted however emissions are not an issue, I can bypass that, this exhaust setup was made to handle big power instead.
Intercooler specs from the manufacturer:
For vehicles with displacement at 0.8-1.5L
．Dimension: 430*135*51 mm
．Weight: 2.6KG
．Diameter of Connector : 50 mm (O.D)

This is a urban legend that still sticks in the turbo mod community. If you calculate how much air in just a one second wanders through an engine, you realize that an fmic with a couple of liters of volume takes absolutely not a lot of time to get filled. Of course, too big is still possible - but then it would have to be a really really big fmic.
Example to show the dimensions I am talking about (efficiency losses are neglected here to keep it simple):
1 liter engine = 0.5 L of air per rev.
0.5 bar boost = 1.5 times the amount of air
@ 3000 rpm = 50 rounds per sec.
50 rps * 0.5 L * 1.5 = 37.5 liters of air per second
You can see that even an intercooler with about 4 liters of volume gets filled in almost a 10th of a second here. And I guess his intercooler isn't even that big
