Sebring Silver Build
Sebring Silver Build Guys,
I've read countless threads and I am still contemplating which route to go, hopefully you guys can help motivate me in the right direction.
I currently have a procharger P1SC-1 setup on a LS1 engine w/ twin intercoolers. Since the car was recently totaled I most likely will be going with a FMIC setup from Bob, unless I see that the intercoolers are worth the repair.
Budget is around $4000, but I can throw a little more if necessary.
I want to stick around 650WHP.
It's a street car that I enjoy driving every other weekend and stepping on the gas from time to time. Not an all out drag car. No meth, no E85.
Here are my two choices that I have come up with on my own so far:
Option #1:
Build the LS1
Wiseco 3.903 -11
K1 Rods
Stock Crank
PRC 15-Degree 220cc As-Cast Cathedral Heads 64cc
LS9 Gaskets
Speed Inc. SC2 Camshaft
This should but me right around 9 to 5 compression. Correct me if I am wrong.
Option #2:
Sell my engine.
Purchase an L92.
Refresh the L92.
Stock long block.
LS3 Intake
Possibly the SC2 cam (I already have it.)
Let me know what you guys think. I am open to all your input and constructive criticism.
Thanks again!

You shouldn't crack sleeves or pistons at 650whp assuming the motor is healthy and the tune is good. Being a centrifugal blower, the power is linear and max boost is max RPM, which is easier on the drivetrain. I'd run it as is and save the money for future use.
You're implying that I leave the short block alone? I also don't want to deal with the hassles of meth. Just strickly 93 octane. No E85.

Verdad Gallardo Good to hear. Do you feel that the heads are adequate?
Edit: I take that back. I think 64cc with the stock shortblock won't help my cause. I'd probably need 68cc chambers to help bring my compression down and compensate with higher boost to meet the 600-650whp mark.

Many usually get the 317 heads that are 72cc to drop the CR so they can run more boost safely. Being that you're octane limited, it's not a bad idea and 317's also have better flow stock than your current heads. If you found a cheap set of ported 317's it'll take less boost to hit the number.
Link looks good. You already cammed? If not and don't plan to those are fine. If you're going to can you'll have to swap springs. A decent blower cam will make hitting your goal easier at less boost. I actually really like my Titan 2 cam and it would work well with your blower.

Na, haven't used it, but based off the spec's it should work fine.
Keep the AFR in the low 11s and the timing low and it should live if it's healthy.
My really good friend had a P1SC on a ~90k mile stock 01 LS1 shortblock. Had some hand ported 317's, Comp 918 springs, with LS9 Gaskets and that same SpeedInc. SC2 cam. Once he got the fueling sorted out, it made over 600 all day in FL heat. Like 620 (with no-meth) and beat the snot out of it for years. Was a daily driver, and fast car. He never did hurt it. He sold the car to another buddy of his and then the new owner put a D1SC on it. It's still going strong from what I heard last.. It was in a C5 with a single FMIC. It was a nice setup especially for what he had in it. Only thing I would have changed was some BTR dual springs.
I have option 1 in my own car. LS6 block and crank. Wiseco -11 3.903's, K1 rods and stock crank. 227/234 cam. CNC'd big valved stock heads, ARP studs, meth injection... etc... Maxed out a Vortech T-trim head unit with it.. Makes good power and it's a strong bottom end.
Just depends on what you want to do with it..
If you want ~600rwhp. Personally, I'd run the stock bottom end with some better heads and run it til it breaks. However, if you do another motor for it.. I'd much rather have a forged piston LS1 or 6.0 bottom end than a stock piston L92 bottom end on boost.

Additionally, since I will be transplanting the engine, I will also be replacing most of the seals (like a little refresh), is there anything you recommend I do for sure since the motor is going to be out? No need to touch the rings? Sealed power rings or open the stock ones a little more (if so, how much)?
Thanks.
