Hi all

Please forgive me if this is in the incorrect section, wasnt sure were to post it

I have an 84' Prelude EX (2nd Gen - 83-87)



I am thinking of doing a swap but confused what to do

Here are my options

LS/B20 with Weber DCOE Carbs
B16 with 4AGE ITB's
B20 Vtec
F20B
H22

I would prefer to go with the f20b as it sounds like a rather unique and fun motor to have

My main concern is the if I do go with the f20b I might have hood closing issues

I know with the H22 in a 2nd Gen lude there was major modification done to the hood, so is the f20b the same height as a h22

Thanks for all your comments/help

 

I am also converting my car from carb to fi what a mission lol

 

What's the car going to be used for? Daily driver? If so, I suggest sticking with the bigger motors to give you the torque to have fun around town.

 

My car is quite light(975kg) so there has been debate and I am currently viewing other threads too

So the age old question H22 or F20B

And this will be used as my weekend car

 

Fast and reliable: B20 Vtec

 

mmm... I think an OEM motor is more reliable than a slap together. h22...

 

Thanks guys for all the support

I think I have made a decision

Will let you peeps know soon

 

A B20 Vtec is an OEM motor. OEM head - OEM block

 

try and order a complete longblock from a Honda dealer. lol

 

I'm having the same debate.. I have a 97 4 door teggy that I'm between the B18c motor or the less expensive but equally powerful F20b...does anyone have any input on what I might need in order to complete the F20b swap, adjustments of the hood, different motor mounts... etc..

 

just to clarify something. which f20b is it? SOHC or DOHC?

 

if it were me i would stick to the simpler swap. the B18c has plenty of potential. and ill bet more aftermarket support than the F20b.

as someone that makes their living working on cars...........i can tell you with 100% certainty that ease and less complication definitely has a dollar value. you may spend less money on the f20b, but youll also be alot more likely to lose hair doing it.

 

h22a, u can pump out 200hp easly without ripping the motor apart, just outside bolt on's and will be really reliable as a daily.

 

The F20B and H22 are nearly the same motor on the out side. They use the same block as all other F and H series motors. I'm 90% sure the heads are the same as well. So whatever modifications you'd have to make to for an H22, you'd have to make for an F20B. Possibly more sence the F20B's are all OBD2.

Have you thought about the H23 VTEC? The real one, not the frankenstein.

 

never knew there was one lol whats the difference between the h22 and h23 vtec in performance terms and yes I was after the F20B DOHC

 

The H23vtec only came in an accord wagon in Europe. It was also only mated to an auto tranny. So if you go this route, you most likely want a manual tranny and you WILL need something like Hondata or Chrome ect. I believe their is a big thread on it, a quick search should bring it up.

Just with minor bolt on's and a tune, it's deffinently superior to an H22. The midrange is orgasmic.

 

yeah i think i'm stickin with the original idea of an R B18c5... theyre just so effin much $$

 

h2b!!! you get the power of the f/h and you get the gearing of a b!

 

sorry man i didn't see your post before your last one but yea the DOHC f20b motor.. no point at all putting a single cam into a 4 dr teg... the engine bay just looks empty.. and the lack of power without boost

 

i was kinda guessing that cuz i didnt see the point in either of the single cams vs any b18c.

id still go with the c5 if it were me, you can probably build a strong poor mans c5(gsr block, forged rotating kit, pr3 head with some work, c5 cams) combine that with a b16 or c5 tranny(b16s probly cheaper) for quite a bit less than a c5 swap kit.

 

how much WHP are you looking to see?

 

I'm not really looking for power, trying to complete a replica JDM 4 Door ITR, the b18c5 was my original choice but the f20b is literally 1/3 the price of the c5 with the same hp output..

 

Sell your car, and import the 4 door itr from japan.

Or get the c5, the cost of fitting the f20b in will be more than the c5 in the end. And you will have the b series transmission which is better.

 

If your looking for power go with h22 or h23, If you just wanna be unique go for the F20b.
If your lazy to convert to fuel injection do the B20 with carbs <- that would be interesting.
And in the end the easiest middle option would be throw in a b18c(x)

But IMO just get a b20 and run in stock with bolt ons and a itr transmission

 

Thanks everyone for your comments I think its gonna be H22 vtec, but I have to cut to get hood clearance as I want to use the hood with the buldge so I dont want to cut it too much as there are many different supports compared to the std hood see this thread for more info
