But then anyone that knows engines also knows they are just an inferior design.
The engine is nowhere near as strong as a 4G63 or as efficient as a K20/24.
Perspective of what makes a good engine has also shifted. Spending $5-10k for a 200-400whp 4-banger is ludicrous today. And dropping $10k is damn near what it's going to cost to "properly" build a SR20.
Engine Set - $3k
Machine Work - $600
Rods - $400
Pistons - $500
Bearings + Gaskets - $500
Oil Pan - $150
Intake - $500
Exhaust $700
Turbo - $700
Injectors $1000
Fuel Rail + Reg - $300
Cams - $500
Oil pump, 300ZX MAF, Tuning Device, et al +1,000
Clutch - $500
ARP Headstuds - $300
Headgasket - $200
Still got a junk transmission - so CD009, RB25, R154, T56 = +$1,500
Well that's $12,350 right there, and that doesn't even have a FMIC, Fuel Pump, Engine Mounts, Drive Shaft, LSD etc.
Fuck, buy a used C5 Z06 and be done with it.
