ok heres the story i currently have 4 different h22's one is a stock h22a in the car rite now the other is a h22a4 complete short block a h22a long block that i believe the balance shaft broke in and a build h22a long block with pistons rods for turbo which has a spun rod bearing

1. if i wanted to use my turbo block (its dry darton sleeved) is it possible to just put bearings in it and go or would i have to get a new crank and if so can i use my crank out of my a4 or use a crank out of my f23a4 and use the rods from the h22 or would that cause a p2v clearance issue

2. If i was to use my a4 block and use an f23 crank would i have to use the f23 rods or can i just use the h22 rods?

3. I have searched and cant seem to find anyone posting hp numbers on a turbo h2b setup with pistons and rods has anyone done it before and how did u like it?

4. i have heard that u can line bore mains for example if i have a 50mm block and a 55mm crank it can be line bored to fit the bigger crank true or false?

Sorry for all the questions but im stuck on trying to decide what i want to do and these answers i receive will steer me in the right direction so any feedback is appreciated and don't tell me search i already have.

It all depends on the damage. You need to assure the blocks line bores is straight and the next crankshaft you are using is the same. Only a machinist will be able to tell you.

2. If i was to use my a4 block and use an f23 crank would i have to use thef23 rods or can i just use the h22 rods?

A FI setup is a lot more than pistons & rods. As far as it being liked, you have to be more specific to what you mean. If you are referring to HP, it’s the same across the board.

4. i have heard that u can line bore mains for example if i have a 50mmblock and a 55mm crank it can be line bored to fit the bigger crank true orfalse?

Possible, the bearing tangs also have to be remachined. Look at spending $200+ from a machinist.

When creating new post try to keep them on one topic. Most will see the multiple questions and simply pass. Asking one at a time allows a topic to go more in depth. Jumping all over the place will simple spiral your post into Valhalla.

thanks bserious

as far as question number 2 i have looked at both of these threads and it has not given me a definite answer some people are saying u can use h22 rods some people are saying u cant use them u must use the f23 rod so im just looking for an answer from someone who has done it before

as far as question 3 i am looking for hp numbers and 1/4 mile times and i kno its more than pistons and rods but im just looking to see where h2b turbo setups have gotten people

b serious is the man.

hooray for QSD

Some also don't take the time to answer repeat questions. Maybe it's just the method of how you search that's not getting you the answers you are looking for. Use Google to search. Type this is the Google search bar: site:honda-tech.com F23 crankshaft H22 piston compression height.

And the answer is in those link I posted... you have to do the math yourself, rather than someone spitting our the answer lets learn a little bit and understand the content. Again this question and topic have been asked and discussed many times.

Block Height - Stroke in inches/2 - Center to center - Desired deck clearance = Compression height

Block Height: 8.643 (All H and older F Blocks)
Stroke in inches/2: (97mm/25.4) 3.819/2 = 1.909 (F23)
Center to Center: 5.551 (F23 Rod Length C to C)

8.643 - 1.909 - 5.551 = 1.183 Compression Height for F23 Engine when using F23 rods.

H22 pistons carry a 1.221 Compression Height. So you could simply subtract 1.221 - 1.183 = .038.

The higher the Compression Height number, that taller the piston.

So using F23 crankshaft/F23 Rods/H22 Pistons will have the piston .038 out of the hole. Still possible to do, a couple ways to make it happen: Machine the tops of the pistons/ flycut and open up combustion chamber to accommodate.
