I have one of the last LT1 cars and need to upgrade to an LS1. The '01s and '02 are coming off lease and seem tempting.

I figure there must be somethings to look out for compared to the LT1. What are the common engine failure/warranty fixes? I know the power steering pump is a big problem for race track use. On my LT1 this was solved with pulleys but it has a remote reservoir. Are pulleys available for LS1 cars? Do they work or do I need a power steering cooler?

Any easy fix for the rear wheel brake hop?

This car will be used for street and track use including competition but the engine will be stock except for a lid and possibly headers ( if they are worth it)

Also if I get an intake lid is there any difference in power between SS/WS6 cars and regular coupes? I will be altering the suspension significantly so it doesn't matter about the stock spring rates etc.

Another small point. I bought my LT1 new and defintely did not want T tops as they seem to leak. If you have them do your T tops leak? It may take me a while to find a relatively loaded car without them.

An LT4 (as shipped in a few f-bodies) swap is legal in ESP. If you do a conversion, it needs to be a complete conversion (whatever that entails) and not just a heads and cam swap, and you can't mix and match between years or between f-body and vette specs.

I'm not that familiar with the LT4, so I don't know if (for example) the pistons or blocks are different, or if the hotcam ever shipped in an f-body.

Basically, the engine (everything between the intake and exhaust manifolds) is only swappable through update/backdate as a complete, unaltered unit.
