I like arguing about stupid shit so heres my opinion on the two motors
RB25
- displacement and 6 cylinders
- sounds cool
- very smooth
- head design
- top feed injectors
- gay ugly ass intake manifold
- gay heavy engine
- gay inline 6 configuration means the engine is further forward in the bay
- gay oiling system that is susceptible to starvation under high lateral g
- with stock mounts, engine sits higher…gay
- harder to install
- expensive to install FMIC
- costs more than SR
- gay ceramic turbo
- gay tiny exhaust housing that chokes over 11psi and at high rpm
SR20DET
- aluminum (light)
- I-4, so far back in the bay
- easier to make intercooler piping
- cheaper
- S14 T28 is available for cheap, which can push almost 300whp
- engine is nicer looking
- gay sound
- gay head design
- gay side feed injectors
Overall SR20>RB25
