im about to buy a 98 civic ex and the guy swapped out the old engine because he blow a gasket and put a D16Z6 in it im thinking about swapping engines because one its a SOHC (not that i have a problem with them) two i want something that i can get at least 250whp with little mods my friend was telling me to do the k20 swapp since thats like the new thing now but then my friend was saying to do a F20B swap i havent heard much about the F20B swap before i was wondering which would be better just to get around 250whp. im not trying to go all out and crazy with speed this car is mostly gonna be a daily and a show car if yall have any info i would really appreciate it!

 

250whp isn't happening from either without taking the engine apart.

 

i know imma have to take apart the engine and internals and that stuff im not worried about that i just want to know more about both engines and which is better

 

i know im going to have to take the engine apart and change out the cams, rods and such not worried about that just trying to figure more about each engines i know a little bit about the F20B that its almost like the H22 but i dont really understand the craze people are with the K series other then high torque and horse power from it just being stock i just want to get other people opinion on each motor and which would be easier for me to achieve around 250

 

I believe the f20b has iron sleeves which is great for turbo set up, 250whp is a lot of money if you stay NA, my advice go with gsr motor and turbo it can easily get 350whp with a stock motor, my buddy has these setup coming to almost 3 years now at 10psi and all is stock

 

on an F20B? that seems like a good deal

 

F20b is iron sleeved but it is also open decked and has really high compression. I am doing this swap right now. I have seen people get 350whp from a full stock setup and boost at like 7lbs. You need a very good tune as well. Depends on how much work you plan on doing. You can do the mild boost without the worry of the FRM sleeves.

 

yea im just trying to get to at least 250 if i can get that ill be happy and tuned up wise i go to my friend thats a honda tech master to get my stuff tuned

 

and what are you doing the swap in?

 

I'm swapping mine into a 3rg gen prelude. I have a build thread in the prelude section. I haven't updated in a couple weeks. I've been too lazy to get around to it lol.

 

ohh okay dope lol
