Engine Project. What to do?

[hashim]

I have a project sigma wagon 1600. It now has a 4g32b with extractors, 32 36 weber and MSD ignition on a 4 speed box. i want more power so my plans are either new engine, mivec 4g92 coversion (did all the research) which is a bit difficult but is a newer engine easier to maintain. or i wanted to possibly super-charge the saturn (not much research done) it would be cheaper than the mivec conversion but im not sure how practical as i dont know how much boost the engine could cope with stock. my idea was fabricate a plenum to mount an sc12 from a 4agze using a 1600gsr box lancer intake manifold (2 carbs) and mount the weber ontop the supercharger and use water injection. i would also get a retard switch for the msd. reason why i would keep the saturn is that it was rebuilt just about a yr and a half ago. would appreciate any advice.

Mate out of a 1.6L the most ive ever heard of someone getting from an N/A engine is 125hp and that was a massively worked engine. If you want power go the newer engine or the supercharger. People have done the supercharger before and it is effective but what about going a 4g63 and then get it turboed? or even the 4g93 u can get turbo kits for.
Newer engine will be easier for parts (more performance parts for the 4G63 as people upgrade the evo's engines).
Supercharger would be cool, but for power and economy go the newer engine.
With the gearbox...im not sure what standard boxes will fit these engines. I do however know that (depending what diff ratio your running) if you have a 3.9 diff (standard) and running a 4 speed gearbox it will be faster to its top speed than the 5 speeds (due to the gearing).

Sorry its a bit ambiguous as to which way to go but in the end it depens what you want from the car, reliability (stay 1600 stock), performance (4g93 or 63 or Turbo) or power/torque (supercharger). The supercharger will be a lot more fabrication work though.
