FI Motor Build Questions I am piecing together my engine for a forced induction application in my LSx RX7. I am looking for suggestions. The motor is a forged 403 LS2, Patriot Stage 2 LQ9 6.0L heads. I was considering going with an ls6 cam for drivability, but I haven't seen too many turbo ls6 dyno sheets that I liked. It seemed as if the topend dropped off after 6k. Is this usually true for this cam or is there more to it?
Also, I am considering getting caddy lifters if I decide to spin the motor 7k+. Is there a cam/turbo that will make power that high? I have 4.11 gears, so spinning higher is looking more attractive. BTW, the car is an M6 and should weigh in at about 2800-2900 without driver.
Any suggestions on cam and turbo combinations?
Thanks...
