My engine is rated at about 285 hp right now. I'm looking (hoping) to
get close to 400hp out of it. Nitrous and a Supercharger are out of
the question. Is it possible to get a big horsepower gain with:
bigger air filter
etc etc... (smaller and minor engine mods).
One other thing. I'm trying to keep the gas mileage around the same
or better. Is that possible and have 400hp, or am I trying to have my
cake and eat it too.
Can someone recommend engine modifications that will help? Also can
someone recommend a place in San Diego CA that is reputable for doing
this sort of engine work? Thanks...
From the items you have mentioned I doubt you will see much more than 80
HP increase. It is very hard to make a huge power jump of the scale you want
without a supercharger, turbocharger and or Nitrous. Out of all the things
you mentioned headers would be the best bang for the buck. Next I would look
at a chip tuning devise (Hyperchip e.c.t) and also do a K&N air cleaner.
I will be honest when I say that you are really working with a small
motor size to get that much extra power and use it as a daily driver while
also keeping smog legal. You are able to find supercharges that are smog
legal. Other than that, there is a very true saying "there is no substitute
for cubic inches". Good luck.
Thanks a lot for all the responses. When I was first reading exhaust
upgrade kits for the pickup, they weren't adding very much horsepower,
What are some of the headers that people can recommend? I would like
it smog legal (if possible), and most horsepower, best gas mileage
