Have you started on the bigger build yet? Details!

BeastlyB

WOW what a build...

I have a F20B3 but it seems that it is a F22B2 same head and block so if i am not mistaking i could go down this route..
Thank you for sharimg your findings and doing to trouble to make the photo's and share it.

Anybody please correct me if i am wrong about F20B3 being able to go this way.

F20 are Great blocks to!! They used em in some 4th Gen accords!! 90-93 Accords, Euro one I believe!

BeastlyB

I have a 1995 Accord Coupe which was made for the Euro market.

It is the same as the CD5 but called a CD9 and has F20B3 Block in it with 5 speed gear box.

Yea thats what it is!! Cool idea, I guess it didnt catch on!..

kinda started on it but going about it the long way. got me some new toys i got a valve seat machine and a valve grinder. i am looking at some flow benches. my valve grinder is a centerless grinder that holds .0002 tolerances. i am going order some tooling, do a full radius valve seat and back cut my valves to see how it helps. i can install bigger valves and bronze valve guides now. i can do about any head work with the machine. i just got to buy tooling and fixtures which cost about as much as the machine.

jwicecold

You got a small little fortune there in your machine!! Its all worth it though I bet!! I got a few other ppl following your build since I started mine! Im almost done. Just trying to scrape together more money for a nice paint job!! IDK If I ever told you this but Im build this engine for a import tuner magazine for my car!!

I will always stay subscribed to this build! Gave me the info and parts I needed for my 500hp 450whp build . OOOO i can't wait til its done and tuned in for your bigger build

i think this winter if i ever get any extra cash, i spent it all on machines and tooling. i will pull my head do alot of head work, bigger turbo, and still put in a different cam. i will see what the limits of the stock block is.

jwicecold

Im really really curious to see the limits of the stock F22 block!! I always hear they are super strong and usually hold good numbers for awhile!!

update i put on a obx h23 intake manifold and 72mm throttle body. I had to modify the intake to get it to function correct, lots of porting and port matching. i had to surface the flange also to get the intake to seal on the head. it was well worth the time. i have not dynoed the car with the new intake but i had to 25% of fuel from 6k to 8.5. i ran same et with higher mph on 2 psi less boost.

ashb82

i figured out the reving issue i had, INTAKE MANIFOLD

jwicecold

I was looking into those OBX h23 intake manifolds as well!! Im surious to see what the WHP gain is!!

I really hope to start my build soon and copy what you did using a F20B3,
if i am not mistaking it should not cause any problems doing what you did as the pistons and driveshafts will be changed giving it the same stroke.

From what i have found only the stroke is the big difference between a F22 and a F20..please correct me if i am wrong..

At the moment saving and put the coupe in the garage,
bought a EC9 D14A1 1989 Civic to drive around cheap while i will spend my cash redoing the motor.

ashb82

I have no idea about about the f20

BeastlyB

Found this great website that has all the Honda cars/engines in view with the part numbers for each component.
This is the F20B3 used in the 1995+ Coupe exported to Europe

Here is the F22B3

Im really interested to see ur build!! Ive always been a fan of the F20 motor but never owned one. Great platform for a build though!!

BeastlyB

At the moment i am saving up and trying to find someone who can confirm we are talking about the same base Cylinderblock..F20 and F22.

I have been told it is the same base block even the same boring but the stroke is different, i am a complete novice in all this and taking a huge plunge into the deep and unknown.

Ashb would you be interested in doing Customer work?
I am thinking about Cylinder head work.

I am hoping my build will be done in 2 years from now, that includes body work repainting and collecting funds for this all.

Thinking about a Carbon hood front fenders and trunk lid to shave some weight of the car.

What do you mean you figured out your reving problem?

jwicecold

It should be pretty close to the same as the F22 block. The stroke however would be different because its DOHC!! Also your compression I believe is different as well. How much did you end up paying for your F20 if you dont mind me asking?? Also where did you get it from??

Waxaz420

Awesome setup man, I am working on a h22 now, and I like this setup, did you ever get it in the accord and if so how hard was the pull? I want to keep AC but I am SO tempted to just throw my h22 in a civic/turbo 15 psi and run 11s all day... but again... AC is important to me... hahaha

jwicecold

He put his F22 swap in a civic. Im doing an accord build with this exact setup!! I was curious to see what my numbers would be so I decide to go with this setup for best results and cheapest cost!..

BeastlyB

Heya,

I think you are thinking about the wrong engine,
Mine is a 16 valve SOHC F20B3 it comes in the 1994-1997 Accord coupe exported to Europe..so it came with my Coupe.
https://honda-tech.com/forums/honda-accord-1990-2002-2/1995-f20b3-cd9-coupe-3079426/
You can see in the link i posted in previous post what components and head etc etc it is made off.
I used Google translation and it worked just fine.

GhostAccord

The SOHC F20B3 is a de-stroked F22. From what I have seen, the parts are all pretty much the same! Aside from the obvious crank and rods.

BeastlyB

I am sorry for the questions but i just wan't to be sure before i start.

Some of the things i will need to outsource since i do not have the equipment or the skill to do some of the things needed.

But as it is a destroked version it would mean that the base block can be used for an exactly the same/similar build as this one..
please correct me if i am wrong and missed something.

Cheers,
Jaak
