My standard LS1 bottom end is still going strong but it still hasn't been added to the original list, here are the current details:

Maggie MP122
10psi, 507rwhp
Miles at time of install - 59k
Miles on the car now - 73k
Broken - N

Standard bottom end is still running great and bores looked good when we installed Patriot LQ9 heads. It's had about 10 dyno runs in that time and about 10 1/4 mile passes with a best so far of [email protected] so it's no slouch.

2006 GTO with completely stock LS2

- APS Twin Turbo
- 7.5 PSI / 554 RWHP / 574 FTLB
- Install turbo kit at ~21000
- Currently at ~46,000
- Motor was fine for nearly 2-1/2 years. I drove through some water and the low APS filters picked up water and hydrolocked my #7, breaking the wrist pin boss in the piston.

Replacing with forged, wet sump LS7 @ 9.25:1 compression

Bone stock '01 long block.

Only thing I have wrecked so far is the stock clutch. That went out at about 4500 miles. Hopefully the rear end will last long enough before putting a 9" in it.
I thought I would include an update:

I changed to the SDCE tensioner and due to the pulley ratio difference, I am seeing about 10.5 lbs of boost now. I recently had the car on a dyno and it saw 566 (numbers in my signature). The car currently has about 58,000 miles, or about 10000 since install.

No problems with the short block, yet. I am keeping my fingers crossed for now.

I wouldn't call it lag, just not make power below 2k rpms.

Turbos and roots blowers can make better power at 2k rpms, centris need more rpms.

Do things like rod bolts improve the stock bottom ends chances of surviving much?

Yes, but that's just one of the weaknesses. My stock engine made 540 rwhp and let go with two broken ring lands and a main bearing failure. Rod bolts wouldn't have helped me much. I drove the **** out of it though, your mileage may vary.

Yes, friend of mine swapped out bolts on the rods and heads and did well over 100 1/4 and 1/8 passes with a 300 shot. He sold the motor in good working order to a bud.

To my understanding ringland damages usually occur either out of poor pcv set up and or running a little lean. The 1st one to go is usually #7

So rods and head bolts, plus was planning on doing bottom end bearings, anything else without going all out on a forged bottom end?
