Im a Daliy Driver, i drive to work and school, "15 miles a day 5 days a week" Im going to drop a LQ4 block and Go with a Single Turbo System on my Trans Am.

But i currently have a 3600 Stall thats rated 550rwhp. i want a better mpg than what im getting. "im getting 10mpg on a Cam, Stall, and shitty tune"
Im wanted to go turbo and was thinking will there be a different if i switch from a 3600 to a 2800 stall?

Im going to be DD with 8-9psi, i dont get on it, and maybe going to the track twice a YEAR. something to drive.

what kind of mpg can i get from a 3600 stall on a stock lq4 block and stock cam, and heads vs a 2800 stall.

im hoping to get around stock or alittle bit lower. Around 16-18 on the city.

stock ls setup with a turbo is between a 32-3800 stall. That is the average setups.

I'd fix the shitty tune first

why even bother going turbo if you dont "get on it" isnt that the whole point of going to turbo...lol..? 8-9psi on a stock lq4 is gonna be around the 550whp mark or so. i think you should pick up a little beater as a DD if your worried about mpg., and use the T/A as a toy...

X2. This will probably fix your mpg issues and make it feel like a different car. For example, I have 4.10's, a Vig 3600, a 240/244 cam, heads, etc. I get 20~22 on the highway when the converter is locked up.
