You need to slow down with all this stuff and do some thinking...
1.) Yes, Del Sols are cool, but they're also slow and heavy compared to other Civics. The convertible top makes them heftier than the average Civic hatchback or coupe. If I wanted to build a fast Civic, I probably wouldn't pick a Del Sol...
2.) Do you have any clue how much money it's going to cost to build a 600 horsepower Civic? You could easily end up spending 15-20 grand on this. You have to remember that it's not just the engine build (which is gonna be very expensive), you'll also have to think about the transmission, differential, axles, suspension, tires, traction bars, etc. Without all that stuff taken into account, your 600 horses are going to be useless...
3.) Did you seriously say you're gonna do Supra tails and an Evo 3 front end? Dude, pick up an issue of Honda Tuning...nobody does that crap anymore...you'll most likely get laughed at if you turn your whip into some "Fast N' Furious" mobile...
4.) Just because you've messed with DSMs doesn't mean you know how to build a Honda. You need to do a lot of reading and research before you even touch a Honda engine or else you're gonna screw it up, big time.
And...my final point to you...
Maybe you should consider chilling with the car stuff right now and just focus on your other interests. I'm assuming there's a reason the cops took your Eclipse and all your money...and it probably has to do with you being a jackass of some sorts? Do you really need a 600 hp car to get in trouble with right now??
Just my 2 cents...take it or leave it...
