04 Sunfire engine upgrade options
Wednesday, February 10, 2016 4:31 PM
So my names Dylan, new to the site. I'm kind of interested in turning my sunfire into a sleeper. I'm looking around at options, for some of the more experienced guys on here what would be more worth my while, ugrading the l61 I already have or doing an engine swap to something stronger and better? I've done nothing to the engine thus far.

Thanks!

The stock L61 can hold 250-300whp with a good tune. Boost it and be happy.

I am making 260whp/250wtq with a supercharger on mine and the car has been very reliable.

At which pressure of boost you run ? And do you need to buy a computer and work on them ?
