Basic things are needed:
1. Engine & transmission
2. In depth understanding of Toyota Wiring
3. General understanding of electronics
4. Excellent fabrication skills
5. Motor & transmission mounts
6. AC lines, fuel lines, water hoses, radiator, tranny cooler
7. Custom headers & exhaust
8. The financial ability to complete.
9. Etc. (all the other stuff I'm too lazy to mention in this thread)
My questions are:
1. Which V8? (I see a couple of options)
a. The obvious, A 98+ 4.0 or 01+ 4.3
b. 2nd obvious: 4.7l A little heavier, but available bolt on supercharger.
c. LS1 or LS2 small block chevy.
Each motor will require custom mounts, exhasut, driveshaft and wiring.
The lexus motors will have more compatible sensors for the IS body. That's a given. Not to mention, most Toyota dealers can service it.
The GM LS series motors have the available support of aftermarket parts second to none. Including LS1 edit, less expensive auto tranny upgrades, stand alone wiring harnesses to make wiring very simple. The ability to run 500+hp naturally aspriated.
As I did with my winning Sport Compact Car USCC MR2, I intend to build JIGs of everything so that I can replicate the parts. This brings me to my last question:
2. Which engine would be more "marketable" if someone were to offer a "kit" making the V8 swap essentailly a weekend project for the competent weekend mechanic. The purist in me believes that the Toyota V8 is the only way to go, however the experienced hotrodder in me tells me to strongly consider the LS1 engine.
Thanks in advance for any constructive help.

Do you think it's gonna make more power?
is300allshow's car has a V8. It drops in.
But is it worth it? Boost your car and you'll have plenty of power. Why buy another motor and do all this stuff to have a non-boosted motor?
For the same price you can be mid 400's at the wheels.
