I have a 98 honda 5spd with a f22 in it with about 300k on the engine. I just bought a h22a4 and would like to know 1 is there a big difference between the h22a and the h22a4, and 2 what can i do to this engine and what type of parts to buy and where to start

notAdiesel

start with the search function. i don't know the answer but i know i have seen a lot of info about them. i would recommend making a word document so you don't forget the differences

FunnyVictor86

a couple obvious differences are:

-h22a is jdm ... has a higher compression ratio ... depending on the year can be obd1 or obd2
-h22a4 is usdm ... has a lower compression ration ... and obd2 only

so if you re sleeve the block and put different piston then you can have the same compression

FunnyVictor86

im not 100% sure if those are the only differences ... unfortunately im not yet too familiar with H series motors ... but with a stock h22a4 you can actually have a chance of getting your car registered legit with that h22a4 ... a jdm h22a will never pass ... at least not here in california, the emission **** state ... but if thats not an issue just get a h22a it's cheaper than getting a h22a4 and making it a "h22a clone"

rcj

i have the h22a4 already, just wanted know what the big difference is and now what type of performance parts should get or put on

FunnyVictor86

that really depends on the route you want to go and your budget ... with a small budget you can probably only do bolt-on's ... which is nothing special ... but if you have money to play with then you can start building from the inside out ... which is where real power comes into play =]

rcj

so what should i do from inside out. where do i start first

notAdiesel

by taking it apart :D duh lol

rcj

i know that duh, i mean wat internal work should i have done

So you bought a motor without doing any research before hand?

Look in the FAQs in both the Prelude and Accord section.

Its probably a typo, but I just have to pry.

Why do you have an F22 in your 98?

Props to that motor for getting to 300k though.

one problem that is common with that swap is the drivers side motor mount, there is a bracket that connects between the motor mount and the bracket on the car and they do not line up properly and it causes it break the mount bolts. i am sure you can find out more about it in FAQ'S. i have the same setup 98 accord coupe 5 speed with H22A4 and when i was running a stage 3 clutch it was breaking the bolts like once a month but now i'm running a stock clutch and i no longer have problems with it.

rcj

so what did you have done to the engine on your h22a4

GhostAccord

What are your power goals and your use for the car? you keep asking what to add to the engine. You have never said if you want to stay naturally aspirated or go forced induction.

Here are some parts to consider replacing;

Block
Water Pump (OEM Honda)
Oil Pump (OEM Honda)
Balance shaft eliminator kit (Kaizen Speed)
Ductile Iron Sleeves (Darton M.I.D)
Forged Pistons 85-90mm (Wiseco) Compression ratio depends on engine use, pump or race gas, N/A or boosted)
Connecting Rods (Carrillo)
Con rod & crank shaft main Bearings (OEM Honda)
A master rebuild kit (OEM Honda) It will have all the head & block gaskets & seals

Head
Port & Polish (CCCylinder Heads.com) Type of porting depends on the build - street, mild or race.
Valves (Bisimoto)
Valve guides & seals (Bisimoto)
Valve springs & retainers (Bisimoto)
Camshafts (Bisimoto)
Rocker arms (OEM Honda) This is the most overlooked part in the valve train, a must to replace if building a race engine.
Adjustable camshaft gears (Bisimoto)

External
CA or SR intake with a good filter (K&N)
Larger throttle body (64mm) Send your stock TB to Maxbore
Ported intake manifold - Euro R if possible
Last but certainly not least. A good free flowing header & exhaust system. Piece a system together yourself. There are lots to choose from

I may have missed something

Cheers

On mine I just changed all gaskets and seals also added a CAI, Skunk 2 cam gears, timing belt, water pump thats pretty much it.

Oh yeah and also DC header.

basically my goal is to have about 350-400hp under the hood. i want to create a total sleeper, where it looks just like a regular stock honda except when i take off you will know thats it not
