Talking ST74 doing some light work on a 3.8L

https://ls1tech.com/forums/texas-members/896561-614-rwhp-my-little-v6-picture-short-video-inside.html

just getting started. Need bigger injectors and swap valve springs. We plan on turning it up to 30 psi..

That's awesome man... I'm giving you an A+

What are you mods so far? I'd be interested in hearing what you've done to make that little sucker hold up to the punishment.

All boost. Very impressive as usual. 30 psi in the future sounds fun.

Kyle,

Unfortunately it is almost the same $, at least a 346 setup that is, unless you use a L67 build which is very cheap, should hold 500 rw no problem..

This particular car gets ~15 MPG lol but on a stockish setup it is almost stock.
