Resolved 1G GS to GS-T Conversion

[JLavetsky]

About 20 years ago, I converted my brother's 94 Talon ES to TSI. We bought the stock turbo setup from a 1G off ebay with most of the parts needed. I think I supplemented what was missing with extra parts I had from either my 97GS-T or 90 TSI AWD. The car ran great for years with the stock 1Gen turbo setup at low boost. Never and issues except a couple times lost al boost when the internal wastegate actuator came off (cotter pin fell out).

I recently purchased a 92 Eclipse GS with the intentions of doing the same. The problem I am facing is, it was 20+ years ago and I don't fully remember everything that I did. First, I understand and agree it would have been better to buy GST or GSX, but lets agree there is limited/no inventory for the low price point I was looking to invest.

Can anyone provide some insight what is 100% a must to replace from my list of parts I do not recall swapping/installing?

OEM Stock parts installed:
Turbo manifold
14B Turbo
Oil and Coolant Lines
Side mount intercooler
All IC hoses and 1G BOV
2G downpipe (old one from my 97 GS-T) - Test Pipe added to make up shorter downpipe
Throttle Body Elbow (I think I probably did do this)
Turbo Fuel Pump (I think I remember installing this)

Parts I don't recall installing:
Turbo Injectors
Resistor Pack
Turbo ECU
Turbo MAF
Turbo Throttle Body
