mmmm.... I have an SRT-4 and a 2001 Civic DX coupe. Im getting bored with the SRT and i was thinking of dropping that in. I understand K20 is the most popular, but think of this, the SRT4 Bolt on possabilities are widely available. $400 Upgrades the ECU to Stage 1 (increasing power due to fuel mapping changes), there are kit upgrades for the SRT which could upgrade Turbo, ECU, Injectors, WGA, Manifold ect. I think the power possibilities for the SRT 4 is just as good as a K20 (K20 is an expensive engine anyway). The question is how would you keep that Torque/power on the ground...Possibly Traction control. Im contimplating wether to do the swap or not, i already have the SRT-4 complete car and the 01 Civic which weighs 2405lbs according to edmunds.com. The SRT4 weighs 2900lbs. Not to mention the possibility for Carbon Fiber on the civic. I have seen Front bumper, Rear bumper, Front fenders, hood and trunk carbon fiber parts for the civic. Lets just say, if anyone can succesfully do the swap you will win contests if you enter for creativity. Combining USA with Japanese. Just my opinion.

BTW im new to the board from California.
