My Name is Lorelei, I'm 33 and about to buy a project car. I'm looking at a 96-04 Coupe with a manual for an eventual high power street build. I don't particularly care if it's a v6 or v8 to begin with, though having the v8 would be nice to get the LSD and proper rear end with, though i'm not even sure that'll matter that much at the power levels I'm going for.
Is there some major issue with using convertibles as a base as far as high power builds (800hp) go? This is a long-term project but I do have the build laid out.
Going to need to take another look at fuel because i'm worried about 93 detonating too early. Cooling systems are not my forte, so i'll be looking at options there too. So far I'm looking at a -8 or -10AN setup.
My wife says I should look into a watts link setup, but also that since this is a street car I might have better luck going with a nice Panhard bar and torque arm setup. My wife definitely knows more about suspension than I do.
I am cleaning up this thread a bit as we go. Bare with me.

Will update more as I go. This build hits 12.85:1. This does not include fuel delivery solutions which I intend to purchase separately.
More as I go.
The above parts without labor are roughly $6500 and that does includes the engine build (less the block), and all the swap mounts, oil pan, and swap headers. The T56 Magnum XL-F is around $4000 with a proper setup, but add a clutch and we'll go from there.. A completely stock, running, higher mileage L92 with running gear (less transmission) can be had for around $3500. putting this swap right at $10,000 to get off the ground running and driving. I can sell off heads as a core if anyone will take them, or just try to sell off the parts at market value individually.
Ramblings and other thoughts
For anyone who is wondering about the apparent off topic nature of this thread, I was originally looking for a convertible. I have since moved to looking for a coupe unless an absolutely screaming deal comes along.
Stumbled upon this for gearing calculations: https://www.blocklayer.com/rpm-gear.aspx
