deciding i will be doing a swap sometime in the year 2013

[ne0tas]

Now i may be doing one this summer or later but i will be doing one in the following year. Now i cannot decide for the life of me which swap. I am stuck between the f20b and the j35a4 swaps.

Now with the f20b i get real nice torquey motor almost the same as an h22 motor for less than 600 bucks but parts have to be shipped from japan if something goes bad on the motor.

The j35a4 is a motor with the a real nice flat/high torque curve and is reletively cheap to get for the amount of power you get but the transmission is hard to find and the mounts are pretty pricey.

f20b cheap, fuel efficent, high revving motor would take about one weekend to complete.
J35a4 fun, torquey as heck, different than what everyone else has.

I dont care about how much work has to be done for each of them im trainint to be an aircraft mechanic so im going to need to practice cutting/electrical stuff
Also money doesnt matter up to a certain point. Im goinf to be buying stuff for the swap slowly as im a student and on student budget lol i dont care how long it takes me to get all the parts btw just keep that in mind

Any input is that portrays to the thread is welcome.

A f20b can be rebuilt using other parts that aren't specifically found just in the f20b. Plus if they motor did have a problem, rebuilding with aftermarket internally would be cost effective and potentially offer much greater performance.

The J-series engine came in a s**t ton of different models, past and present. There are a bunch of used transmissions that could be at your disposal.

a f20 is not fuel efficient. A D-series hx, cx, vx, dx motors were build around fuel efficiency. With tuning, the f20b and the J35 could produce the same MPG.

What is your certain point of money you're willing to spend. That could ultimately decide your swap for you. Neither of these swaps are cheap, even though you can get a big piece (the engine) for much less than most honda swaps

Im looking for around 2000-2600. Im just looking for a reliable DD that i can call my own and to have fun with at the same time and not looking to rebuild unless i really have too. I have seen threads and calculated thoughts. F20b is about 2k. J35a4 is around 2.3-2.5k which is the sweet spot for me. I would be willing to spend whichever amount on either of these two motor swaps and i know i would have fun during the process. Im leaning more towards the j35a4(the one from the odyssey) because the torque these motors is just inbelievable and they look kick ass in small civics like mine. Theres not that much info out there though about it so im a little scared.

Your total cost will be higher than that for both swaps. The J-series is a bit more involved, and even doing every detail you possibly could on your own, you'd end up spending more that $2600. If these two swaps were that cheap, they'd be done a lot more often because there would be no point in going another route. The cost is deceiving because of the cheap longblock prices. The odds and ends add up.

Well no matter i will still be saving up for either one and buying parts when i can. When i put my mind on doing something, i will do it no matter how long it takes lol just trying to see advantages of both swaps and yeah. Ive been reading more and more of the little info i see on the Civyssey and im starting to lean more towards it because of gobbles of torque. Im a torque kind of guy i guess xD

 

[emerican]

Agree with child that price range you mentioned is reserved usally for b series swaps so you will have to save up a good bit more to do either of the swaps you said you wanted.

 

[ne0tas]

Hm well now you guys are making me reconsider :s Maybe I should just do an auto to manual swap and call it a day?

 

[CHILD]

oh wow, if your car is auto now then you'd definitely have a lot more you'd need to invest to swap motors.

 

[ne0tas]

Yeah sounds like i should just so an auto to manual swap lol a lot simpler and cheaper i guess and less tooks to buy too. Gues ill just stick to engine swaps after i graduate school

 

[emerican]

that may be your best bet there are a good bit of write ups on auto to manual swaps just look into those.

 

[mymmeryloss]

However much you plan to spend, i suggest adding atleast another $1000 to that number and thats how much you will end up spending...

and one thing i'm confused about is the 3 pin to 2 pin ideal. I have a 99 Civic Ex and I know I have to swap out the Intake manifold to a manual one but I'm not sure if I have to repin it? it doesn't exactly state if the 99 obd2b manifold is the same as my 3 pin?
