Ok lately I've been hearing a lot of debates n things about which one is better. I heard that ppl are turboing F series but the ppl with H series say that the gears are too slow in F series. I was wondering since both of the blocks are about the same. Could you just get a tranny from an H series to shortin the gears? And Im confused as to why ppl are saying that H series doesnt give you alot of extra horse power. It's dual cam I just thought that would help. I dont know if I just want to leave my F23a1 in and turbo it or get an H22 and turbo it. Also I heard that most ppl are turboing f22b1's. Are they better than the F23a1's? Im trying to learn as much as I can before making a big decision cause I dont wanna be out a lot of money if it can be avoided. thanx for any info. sorry bout all the lame question's Im new to the accord family.

 

This thread should answer most of your questions: https://honda-tech.com/zerothread?id=1435018

Yes, you can swap an H-series trans onto your F motor. More acceleration, less fuel economy due to higher revs. The motor is going to be chugging along at something like 4000 rpms at 80 mph.

An H22 swap itself is going to give you a boost in acceleration. What most people complain about with 6th gen Accords though, is that our cars are pigs... An H22 swap doesn't give the results that most people are hoping for.

F-series turbo... The block has iron sleeves and a boost-friendly compression ratio. You can have at it all day long on "low boost", assuming it's tuned well. A bad tune will kill any motor. Tuning is very, very important.

 

If you just swap a h series tranny on a stock f motor (ecu stock and all that....), you will notice slightly quicker take off, and less time between shifts, but that will take some of your topspeed out (but i don't think you are really trying to brake any speed records right?!).

If I was you man, I would go with some bolt ons first: intake, header, full exhaust, pulleys, get your intake manifold ported (and throttle body too), consider a TB spacer and reset your ECU to your specifications.
You might be satisfied with that, or then you may wanna consider the turbo, either way, just going turbo out of nothing will get your wallet empty in less time than you think. After you install a turbo, there will be a bunch of "..now I just need to get this..." and "...oh.. i need that..." in order to run the turboed f23!
Do some more research and see what you can come up with as far as the info you are really looking for!

 

I'm debating on this too, although I'm at a point where I'm leaning toward the H-series. I'm aiming more towards circuit than drag. I've also heard that the H22 gears are longer than the F22B1's (which is what I currently have). Btw would you need to reinforce or change anything on a CD5 if an H22 (auto+m. tranny) were dumped in it?

 

thanx guys for all the info. I'll be doing sum more research n thanx for the link. I might jus keep my lil single slam motor. I'll jus build up on this on for a while.

[EDIT] k jus read your thread on this n uhh looks like I got the shorter straw of the motors. Ok so if I turbo my motor it'll eventually give in right? so should I look for an f22 bottom end since it's stronger? Cause I dont wanna put uber amounts of money into my motor if it's gonna break on me.

Here's why I completely disagree with this... Bolt ons don't do much. I'm sorry, but they don't. Intake, sure, a couple horsepower. Will you feel a difference? No. You might feel a little difference with a header. But wait... If you are going to swap an H22 or go turbo later on, you just wasted the money you spent on the header. Pulleys? I guess that's just a personal preference, but I really don't feel like they do much. Ported intake manifold and throttle body? Again, just a small gain that you're probably not going to feel. TB spacer??? I've said it before, and I'll say it again... They don't do **** on Hondas. Nada. Zilch.

scabbs,
The first thing you would need to decide is how much power do you want? What kind of goals do you have for this car? The F23 bottom end is fine for low boost, meaning somewhere in the 200-230 whp range. Above that will all depend on how good your tuner is. Good tuner = no broken parts. Or you can pick up a set of pistons and rods, and then you would have a semi-built block that should handle around 400 whp or more. (Depending on tuning, of course.) But... If the last thing in the world you would want to do is risk reliability, then maybe an H22 swap would be best for you.

I noticed you're 18... so I'm going to give you alittle more advice. Turbos cause problems. Something usually breaks at some point, unless you're one of those guys who always has everything go there way. But unless you are, you need to have money set aside in case something does happen. Personally, I would not choose turbo at your age. They can be a lot of work, headaches, and money.

If I were you, I'd either get an H tranny (if you don't mind losing a little fuel economy) or a full H22 swap. But that would really just be my personal preferences...

 

an h tranny on your f series is one of the best mods you could do.

I had a 91 accord with a F23A1 w/H23A prelude tranny. It was such a fun car to drive.

1. it wont take away any top speed

2. TB spacer? no

3. reset ecu to specifications? wtf are you talking about?

 

Im totally diggin the info from you guys n personal perferences. I totally dont have a lotta money to be shellin out. Ok mabey I'll do the H swap keep my F for later down the road. Swap the H then work on my F as a side project. Since it's out of the car it'll be easier to work on n do what I really want with it. thanx guys

Well, it would lower the theoretical top speed, but not the top speed that the car would realistically be able to reach.

Agreed... I just forgot to mention it.

it is a good mod but i like the 1995 accord ex tranny with the h22a.
the third and forth gear are alot closer and you will get better gas mileage with a lower 5th gear. h22a+7psi+95 ex tranny=more top end speed

 

Is it possible to put a H22 manual transmission (97-01) in an automatic CD5 w/ F22B1 block?

Yes - pretty much all H/F blocks/trannies are interchangeable whether they're manual or auto.

 

as a previous owner of a 99 5spd accord, and now owner of a 2001 prelude i think the best improvement on the F23A1 would be a higher compression piston. they definatley have a (-) dome so some higher comp pistons and a mild cam would most likely do alot on the F23 but im an N/A ****. it would be a really nice motor to build up for a turbo though. once again, its pretty much got turbo pistons and a closed deck, iron sleeved block so other than head internals and maybe forged rods, you are ready to boost. torque curve on the SOHC is also very smooth. i always wanted to try to put an H22 head on the F23A1, but then again, i was overly in love with that car. i ended up putting it into a tree and ended up with the prelude.

BTW: the H series block is CLOSE to the same on the JDM H22 w/ the closed deck. my usdm with an open deck is a whole other thing.
