Acura/honda integra v6 swap?

I was wondering how much work, money & time it would take to do a v6(6th gen accord v6) swap on a late 90s integra

Considering you may be making that 4 banger into a v-6 you will need to heavily modify the engine bay even to get the thing to fit. If you have the original Accord you will basically be taking EVERYTHING from the accord engine, transmission, ECU, cooling, ignition system, wiring harness, exhaust, and a plethora of other little things. This is a HUGE project and has a high rate of not working at all. Most of these swaps never work unless you know what you are doing like Really know what you are doing. So as far as cost you will need that entire accord for parts or piece together 2 or 3 wrecked accords for all the necessary parts. Time it could take a month with a fully trained crew and a full shop or it could take years piecing it together in a carport. Money. Take the value of the Integra now roughly 800 bucks add a zero and then another 3-5K. To do this right plus any after market mods you wish to add on your over 10K. Just getting and rebuilding the motor is 2K or more same goes for the tranny. No reason in putting untested used parts in a car like this so everything should be rebuilt and refurbished. You are doing all this for a WHOPPING 50hp gain all while adding an extra 300lbs of weight. So is it possible sure is it worth it depends on you. You will never be able to sell it for what you paid to do it so you are kinda stuck driving it till it dies. Insurance will never recognize all the modifications so if you total it expect an 800 buck check to cover it.
