Default Ls7 upgrades

Does anyone hear know a figure of how much it’ll cost to get a ls7 to 2000+ hp on top of the 5 grand turbo

Default Depends on what it’s for and how reliable you want it to be

I would bank on, roughly:

15-20k for the short block,
10k for heads, cam, and intake manifold
5k for ECU and fuel system but could be much more if you want really advanced data logging
7k for intercooler, intake and exhaust plumbing and wastegates.

Then there's the fact that an LS7 engine is a terrible place to start a 2K hp build. Better off selling it and starting with some sort of aftermarket iron block. Ask this question over on the forced induction page. You'll get more traction there.

There is an 08 ZO6 in the shop I use, getting a 1,600 hp engine. It's about 85% complete and at this point, the owner has about $24,000 invested.

The advice above about the LS7 engine being a poor candidate for massive high horsepower overhaul is spot on. I didn't ask but most everything on the new engine that moves is forged, including the block.

I've never driven a extreme high horse power car but would question it's street manners. My car makes 610 rwhp and its a handful.
