Eucalyptus lude

Hey guys, looks like im gonna be picking up a f20b dohc vtec engine for my prelude. I know both engines are OBD2. i will be using my prelude transmission. So what else is needed?
-I know the three to two wire IAC valve change
-The dual vs single water neck sensors.
-Is the h22 dizzy the same as the f20b?
Is there anything else i need to know that needs to be modified when installing this beast? Please help me thank you very much!!
see last page for updates!!!!

im just wondering why ur gonna be putting in a 2 liter motor opposed to the 2.2 liter h motor? i dont know what u need, but i was just curious o_O

SHPrelude00

cuz the F20B comes out of a Honda Accord SiR-T in Japan and it's pretty much just sick! Revs Higher, Faster....but it's also rare and expensive!

actually its been done before i think... it was a red lude w/ a turbo setup im not hating im just wondering why go that route when h22 is more practical

Search the allmotor forum, search for Bense's f20b thread in this forum and/or pm him.

its simple use your h22 intake manifold and your water neck the dizzy is the same exept for internal coil on f20b also delete the butterfly's (secondaries) also the f20b is factory iron sleeves 11 to 1 compression h22 type s cams are allready in the f20b and be series sized valves (smaller than h22) and is de-stroked and revs high as hell its a b18c5 and h22 all in one torque and high revs go for it and all i can tell u is the same thing everybody aid when i built an h22 for my prelude put it in a hatch and do a hto b conversion with an ctr or itr tranny my boy has a 97 ek hatch with a f20b bissimoto h to b kit and a ctr tranny and jun stage 2 cams euro r single stage intake manifold (ported) and a 72mm throttle body and hondata s300 and the car is ******* sick

i would like to use the f20b intake mani cause of the larger throttle body etc..

It's not really that great.

n20h22bb2

just use the throttle body and also your supposed to change all that the intake manifold the throttle body and such come on your going to do an f20b swap and then get cheap and the throttle body's are the same size on the h22 and f20b

n20h22bb2

the f20b is twice the motor the h22 is

i've got this theory i've been turning over in my head for a while...

could someone use the crank and rods from a h22 and put it in a f20b? that way you could have the hp, AND extra torque, and still have iron sleeves for even higher compression.

or better yet, could you use the rod and crank from a f23? just a thought..

journals arent the same, but a f22 crank would work

97LXF20B

you could do crank and rods from a H22A4, but you can't have it both ways. Either you leave the stock iron sleeves, maybe you can bore them to 85.5 or 86mm, and then you lose HP because you lose some ability to rev and you still have less displacement than H22 so less torque - or you re-sleeve to get out to 87mm (stock H22) or whatever higher bore you could re-sleeve an H22 to, but then no more stock iron sleeves.

DCxMagus

ok H22's dont suck just because they aren't the best motors on earth to boost in stock form.

Personally if I was going to build a motor from scratch I would attempt the G series motor simply because of the massive increase in torque over the H22 with the same amount of power.

But for all of us that don't want to turbo or can't because we know we don't have the money to do it right so we chose not too, the H22 is a great motor for the prelude just takes a little tuning to get it running good(factory tune for them is crap imo)

ok so heres the update
-Bought f20b great condition!
-Power enterprises timing belt
-Has Greddy spark plugs
-Got obd2-1 conversion harness with chipped p06 ecu with vtec conversion and chrome pro..with ostrich
-Started to put the H22 engine harness on and am still working on the coolant neck etc
-Need to do the CFK to CFS mod because i dont want to use my h22 oil pump.
-Need to switch over to external coil.
Ill keep you guys updated!

Your an absolute moron. What the hell does reving high have to do with a better. Leave that out of this debate ricer. The only advantage I see is iron sleeves as opposed to FRM. That being said I and most people on this forum would respect and revere a sick all-motor Prelude over a ebay turbo lude.

you buy all that junk? power enterprise timing belt greddy spark plugs? chipped ecu...

Eucalyptus lude

um why is that bad? your in idiot

vinuneuro

Use the NGK plugs.

Eucalyptus lude

ok,the dam spark plugs arent that important right now. LOL i need to do the dizzy conversion, finish with the intake manifold wiring and then work on tuning a good basemap! getting my bung welded in on friday! So ill keep you guys up to date

Ht noobs are out of control.......not referring to the OP either!
congrats on sacrificing the TQ.....
Bigger is better....anytime---anywhere.
Turbo this and Turbo that......see Md23vtec's setup! No F20 in there.
