(I'll find more flattering photos of them some time)
'98 VW Jetta on the left. '03 Golf on the right.
Jetta has 285k miles. Won't die (just bleeding the brakes). Body is getting it from the midwest but should make a basic development platform.
I have a tune and larger injectors in it but have never had it dyno'd, clutch slips.
Wastegated turbo and a broken wastegate control valve so I have a mechanical pressure valve regulated to ~17 PSI.
Stock: 66 kilowatts (90 PS; 89 bhp) @ 4,000 rpm; 202 newton metres (149 lbf·ft) @ 1,900 rpm
Golf has 160k miles. "New", the injection pump just ate itself which is a great excuse to get a larger one. (11mm over 10mm).

Has larger injectors and a tune. But also never been dyno'd. Clutch is slipping (Not looking forward to doing clutches, so I just go easy).
Variable Nozzle Turbo (VNT). Tune set at around 16 PSI.
66 kilowatts (90 PS; 89 bhp) @ 3,750 rpm; 210 newton metres (155 lbf·ft) @ 1,900 rpm
