I don't know if you want my opinion on that. I mean its up to you and what you want to do really.
That motor itself is decent but I can't tell you if you would feel like its worth the work and doing the computer swap with the wiring change.
I'd hope that someone here has done that swap and can tell you more about it than I can.
My friend has done a few dohc swaps before and they've turned out good.
For the time and price of the swap, you can find the whole car on craigslist and be done with it. Sell yours and buy the V8. Just opinions throwing around.
I'm happy with my v6 cause I own other high hp cars. I'm really thinking about keeping my v6 stock and buying a 2004 cobra
like I want.
(sorry, went off in another direction)
If you want simple, just go with a turbo kit on your v6.
You can get a tuner, a turbo kit, some injectors and run 6 psi of boost and be happy. All your A/C stuff will still bolt up and you'll keep your sanity. LOL
But, if this is your only daily driver, i'd say find another car to mod, cause it'll be down for a long time.
