s5 n/a into s4
Id like to get as much power out of an n/a as possible. I have an s4 n/a. Should I bridge port, do this, and do that to an s4 motor, or should I go to the s5. I already know some major differences about rotors, omp, harness, etc, but would it be worth the time to work with the s5 motor (even if the s4 motor will be totally worked over)?
If so, Could someone shoot up a link with "s5 n/a into an s4" info? |
ive never done one before but i've heard swapping an s5 motor into an s4 car is a pita
|
Any ideas? S4 motor with S5 rotors, maybe?
|
can you fab brackets, re wire the car, and own a good welder?
|
S4 block it is!

What exactly do you mean by "Most NA horsepower"? do you mean that you are going to give it a big bridgeport and run hardened planetaries and lightened rotors, or do you mean that you want the best stock internals to start with?
The s5 gets most of its power from the variable geometry intake manifold and slightly more intelligent ECU, the redline is increased due to lighter rotors. In the end, we need to know what you are willing to do to get this power to properly advise you. Stages (as I define them) 0: Bone stock --> 120-130 WHp 1: Stock internals, some exhaust upgrades, some factory sensor adjustment, reliability mods. --> 130-160 WHp 2: street or half-bridge ported, many modifications to intake/exhaust/engine internals --> 160-200WHp 3: Standalone ECU, Full bridge or peripheral porting, loud. freeflowing exhaust with headers, custom intake manifold, etc. 200-300WHp |
full PP, light weight aluminum rotors, rx-8 e-shaft, full open exhaust, ungodly amounts of meth and nitrous, full balance and like 30k= fastest 2 rotor n/a engine
