I'm looking to start building an h22a4 for my 1998 Honda accord (f23a1). I've done some research and put together a rough parts list and was wondering if anyone has done a similar build and has some advice or any suggestions. I'm pretty new to engine building and I've heard that an f series to h series swap is pretty difficult swap. I have someone who knows what they're doing to guide me but I'd still appreciate some extra help.

I wanna put in:
Darton high Ductile sleeves (stock bore)
CP Forged Pistons
Skunk2 Alpha rods
Garrett t6 turbo
550cc Injectors
High flow fuel rail (not fully sure on the brand yet)
Cold air intake
Prelude ECU (97+)

Hoping for 450-500 hp and I've read the stock head can handle about 580 whp so I should be okay.

I'm not sure about getting a high flow oil pump. Someone said they run 721hp on a stock pump but sme say you should get a new pump past 300hp.

Parts list isn't fully completed yet and I'd appreciate some help on what else I'd need.

I know there's a lot of posts out there but I'm not sure if some of the info is still useful seeing as how they're over 10 years old. Any help is appreciated. Thanks!

 

A T6 flanged turbo is too big for a 4 cylinder engine. 550cc fuel injectors are maxed out at about 350 wheel HP at conventional fuel pressures, so to make 500 wheel HP you will need a set of 1000cc fuel injectors (larger if you intend to run E85). You cannot use a stock ECU for this... you will need some type of tunable engine management system. A cold air intake will not work with a turbocharger, so unless you are intending on running the engine NA at first, a cold air intake really isn't applicable.

 

IMO no point of building FWD car that much, its not going to be that fast since all it can do is burn rubber.

 

I plan on running N/A until I save enough for a turbo. It's probably the last thing I'll do to the engine. Also yesh 500 hp is probably too much for a fwd but I get bored really easily and want to make my car perfect.

It's my first car and I want it to be something that I'm proud of and love more than I already do. I have an 08 civic si with a blown k20 I could build but I want my baby to be my own.

 

Building old fwd car is pretty much waste of money. You have to also think about traction, suspension things and cooling so its going to be really expensive and with less money youll get newer & nicer car which is already faster than your outcome will be

 

Building the 08 Si would be the better option. Swap in a $1000 JDM K24 and easily make 500-600whp on a stock engine with the right turbo setup. It's a much better platform.

 

One day I might convert it an awd for more traction and handling and every other benefit but for right now I just want to live in the moment and build my engine for me. Yes there's cheaper, easier and more practical options but everyone here understands wanting to make your car truly yours. If there's something you can do to improve it and make you love it more then you'll do it.

 

No, you have to think about how to get your added power to the ground from the beginning.

And thats why we know its waste of money. Its full of headaches and when youre finally there you almost hate the outcome when it gave you headaches so long and youre ready to sell it for way less money you drop'd into it

 

I'm not going to leave the suspension stock. I'll never stance it or camber or anything but it will get an upgrade after the engine.

 

not only suspension but with high power setup you have to upgrade traction bar, sway bars, bushings, LSD transmission etc to get the power to the ground

 

Jesus dude, why are you even on these forums lol? The whole intention of most of the people on this forum is to modify old Hondas, no one is out here thinking they're going to make a profit on a project car.

It's certainly a big undertaking but if OP has the cash, and already has a dedicated daily, if he does the research he'd get good results.

 

reality check. noobies dont always understand what it takes
