My vote goes for a big *** procharger. A guy in the eastern part of the state made over 1300 rwhp with an f3. that will be the route i go when i can scrape the funds together,lol. good luck.

 

Maybe a bad batch of lifters were sent out?

IIRC, means if I remember correctly.

What does lifter cause when it fails? Sorry I'm not very familiar with LS1 engines

 

go with a forged solid roller with high CR and progressive spray! it will be cheap reliable, just as fast and you wont have the extra weight, heat, and headaces of keeping the turbo in good shape, and you will be able to drive it around town just like a good little N/A car.

 

ended up ordering a 416 ls3 and using the tfs heads. then using a dedicated fuel cell for the n20

 

I would go Turbo myself. Its hard to compete with boost. When I get done with the motor that's in my car I'm going to go with either the Procharger or APS setup. Nitrous is cool for now but not something I would build a motor around. Just my opinion.
