Hey i was wondering, i have a 5s-fe engine in my car, is it worth it to make it a good nautually aspired enigine or should i just save up for a 3s-gte. I can do all the engine work myself i am a toyota mechanic. I was just wondering from other people if they thought i should go all out with this engine or just do the the swap. Any thoughts would be appreciated.

i'll agree thats there not alot you can do NA. if your car has an adjustable distributor you can advance the timing a little for a small increase in torque and a shift in the power band to the mid/lower rpm range. its not a large increase and you'll want to run a slightly higher octane fuel after you do this.

another possibility is to get NA tuned with a safc or similar device, that with a header could pickup a few hp/tq in addition to the timing.
