im a p-plater who just bought a nissan silvia s13 non turbo auto (no comment about auto) and i need to know what to do to the engine to make it better performance whise
thanks andrew
im no engine pro builder, but to answer your question
2.2L stroke Kit for sr20
port and polished head
High comp pistons
largest cams available
balanced bottom end and strengthened where possible
ITB Quad setup
custom extractors to suit crazy NA build
those will all add+ KW to the engine
and then the essentials needed to get this engine running
ECU+tune
larger injectors
lighter flywheel+better clutch
better final gear ratio to get to the power band faster+LSD
thats a real rough NA build, i dare say it will push out close to 170kwatw and rev to 9000
but like i said, im no engine builder so dont base it on my info of specs, but if power is what you want, this is how to do it NA style, high comp motor will gain kilowatts
