i even asked on pw and a few other pros, they all say none of the B nor H series will fit this engine, even if it does they will have to do many many alterations, the ecu might be a hassle, and the hood might not close due to the engine bay clearance either, the mounts would be hard to do, and even if you fit it in, it will be hard to do modifications to it, so its not worth the excess amounts of time and money...
a guy in pindi did a swap in a 2005 vti, he had to shave off a few things here and there, and at the end it jus didnt work out.....
the only engine that is swapable and is easy is the k20a, k20a2 is 200 bhp and is very gud but is not available in pak, even if it is it costs atleast 250k and u need an ecu from hondata wich is a kpro that costs around 80k, other than theres a k20a3 wich is 160 bhp and costs around 2 laks (member n20 on pakwheels has it, hes never had peace with his car since he got it) that even needs a kpro...other than that the best is a k20 type R wich one is available at hpr that costs 375k with fitting and its 220 hp.....
i say go turbo, it gives u around 220 bhp and is perfectly reliabel and is bolt on with no alterations....i have a turbo and manifold bolt on for ur model civic for 12k, im not selling my whole kit so u can pair one up from a local shop, it wont cost more than 50k...but yes if i get a good price for my whole kit, ill giv that away as well...
