Looking for assistance getting my 1.6 turbo back on the road.

Looking for assistance getting my 1.6 turbo back on the road.
Used a Bell Engineering kit 8 years ago to successfully turbo my 92. Gave me about 3 years of joy before rings and valve stem seals gave up the ghost. Life happened and getting it back on the road took a back seat. After making decent money last year I saved up to have the motor professionally rebuilt by Race Engineering with the goal of around 250whp.
I know I need bigger injectors than what I have. Its been so long since I ordered them for the first build I cant remember the size but I know I was running a 95% duty cycle. That was on a 2871r at 12psi with my passenger eyeing the wideband while updating the MSPNP on his lap. I still haven't decided on manual or electronic boost control for this new build, but assuming I'm going to need 18-20psi to accomplish my goal.
Here's what I have right now.
1.6 that should take the power
2871r with equal length manifold (old Bell Engineering design)
Walbro fuel pump
MSPNP
Innovate Wideband
Intercooler supplied in kit by Bell
Tried understanding the FAQ on injectors but was left with either needing around 380cc or 440cc. Any help would be appreciated thanks.

FlowForce 640's would be the cheapest good route. The FlowForce 9xx will give you more headroom. ID1050 if you want to never worry about injectors again.
Where in Charleston are you located?

Trust Shuiend. All of those specifically mentioned are of sufficient quality, and properly matched by the supplier, to idle well with your ECU. Random large ones... not so much. No reason to go below the 640's.

The usual reply is "$319?? Oh noes, cant afford that, I only budgeted for Ebay rx8 China knockoffs. I gots cats to feed!
But seriously the ff 640 are amazing injectors. I'm running them with perfect idle and made 309hp no problemo

None of those injectors are oversized. Shoot me a pm if you have not already ordered a set of injectors. I may have a spare set of FF laying around that I could let go of.

I have not seen any mention of the differential.
The ring & pinion gears in the 1.6 cars are notoriously weak. At 250 HP, the OP is fairly certain to destroy it. The '94+ cars used a slightly larger differential, which is much more robust. Replacing this should be on the build list for any high-power '90-'93 car. You will also require the axles from a '94+ car, as they do not interchange between the two diff styles.
