I got a 97 accord Ex Coach Edition Sedan... I just got the car, however, i want to throw an h22 for next summer but meanwhile i want to turbo this motor. It has 160,000 Miles and the motor is cleaaaan as it could be. Runs smooth no problms whatsoever, my question is:

How much power could it handle stock ? I was thinking on trying to run 14 psi, would it hold it ? I dont want to set up a turbo kit and only run 8 psi, i want to go at least 11 - 12 as the minimum. Would it be able to handle that power tho ?

 

with that many miles, you will definately want to tear it down and rebuild it....I am not sure you will be able to run 14 PSI on stock internals for long though

 

What turbo are you planning on using?

 

Neither the H or F22 would live at those boost pressures in stock trim (for very long)
Ironically the F22 is (arguably) better suited for boost with it's lower compression and a stronger bottom end.
Stock, both the H and F22 can tolerate 8-9 pounds of boost. This gets you into the range af 200 to 215hp at the front wheels (by most estimates)
This compares favorably with the 3.0l V6 rated at 200hp when you consider this.
The V6 was rated at the crankshaft, the L4 Turbo is at the wheel. (more usable HP)
The L4 Turbo is a lighter package (better power/weight ratio)
In order to reach the stratopheric boost pressures you're looking for, either engine will require more than just a "refreshing". You're going to be looking at
Forger Pistons
Cleavite Bearings
HD Connecting Rods
Cylinder Girdle
If you expect it to live.

it dont matter to me but if i got to build it what would it be better to build then, the f22 or the h22 ? with consideration in mind that i want to run at least 15 psi as a daily driver. which one would i be best with ? i dont mind about hp gains at this point (as i know that if i did obviously the h22 would be the perfect choice) but i am looking for reliability and some fun... so which one should i build then ?

 

15psi on what size turbo?????

If you don't mind building it and you don't mind the cost then swap and turbo the H22

 

I wouldn't suggest the H22 for boost, for several reasons:
1) The engine is NOT sleeved and requires special alloy pistons, just as the '74 Chevy vega 4cyl used. (refer Honda Parts callout '94 Prelude SI VTec)
http://www.hondaautomotiveparts.com/...NKSHAFT-PISTON
and
http://www.hondaautomotiveparts.com/...+BLOCK-OIL+PAN

The H22 and the F22 share the same crank and rod journal diameters. Only the H22A4 has a larger Main bearing journal.
The H22 has a shorter stroke (90.7mm) as compared to the F22 at 95.0mm; making the H22 rev better but the F22 makes more low-end torque.
Conversly, the H22 has a larger Piston Bore (87mm) when compared to the F22 (85mm)
In my estimation , the H22 makes for a better All-Motor project; but the F22 makes for a better boost platform with it's sleeved block, wet deck and larger stroke.
In order to make the H22 a viable Boost Project, you'll have to find someone that can bore and install Sleeves.

I would not boost an H22a unless its built to the point where it can handle boost. I honestly wouldnt put no more than 5 lbs on a stock H22a. Its got way too much compression and was made to be an N/A monster IMO. F22 can safely handle 8 lbs of boost with a good dyno tune.

 

You guys are talking like you cant turbo a H22....If he plans on boosting an f22 @ 15PSI he must be fairly skilled to keep it in running order to daily drive it. H22 IMO is a good starting point and when he build more money because, like all men, he WILL want more power and wont be satisfied. I say get the H22, run it for a while and worry about sleeves and a turbo later...

 

id rather run the f22b1on the turbo because if thats what you already have think of the money you could save instead of doing a swap.

if you do the h22a swap you have maybe 3 grand yanked out of your wallet

if you dont do that swap you can put that 3 grand into forged sleeves, forged pistons, rods, crank, etc. and then you will be boost ready for your 15 psi you want

then again you could just get a bike.... my 08 gsx650f beats z06's stock

 

ive got a friend funning 10 ps1 on stock f22a1 internals and its been going pretty strong, bbut i would feel more comfortable on about 7-8

 

Totally understand all of your points, now taking on consideration what most people have said i guess the best way to go is f22 turbo by now, until i could find and afford a high mileage h22 and a shop to do all that work for me. i will build the f22 just to let u guys know.. cuz as i said, i want to hit 15 psi dd... but h22 is the motor i rlly want in the car but as it requires a lot more work and money ill just leave that for later and work with what i got... Thanks a lot. I will start a build thread soon and ill reply to this thread when i start it so you guys could keep track of my car Thanks a lot :D

 

umm couldnt rlly find anything for pistons on ebay.. any hints ? and as of for the turbo size... ebay turbo kit... 50 trim t3 prolly

 

Stay away from Ebay kits of any kind. They aren't worth a pinch of shyte! Cheap does not work when it comes to building an engine.

I'm having a really hard time understanding why "H22 enthusiasts" always relate to the F as a week alternative. And they are just going to throw a turbo on it to hold them over. They always say that it's just until they have enough money for there beloved H.

That makes absolutely no sense to me. Why would anyone throw money at an engine they don't even want? The $500 (for cheap unreliable turbo & parts) + 200 for tuning would have you well on your way towards having your dream H paid for. Maybe not installed but at least you would have the engine..... : head shake :

 

lol bro relax... haha the only reason why i do this is obvious... even if i get an h-series i'm going to have to go through the struggle of doing the sleeves and a lot more stuff. that aint going to be cheap... plus after i get an H i need to keep saving for pistons, rods, cams, etc, etc, etc, so what would i do meanwhile ? run on my crappy f22b1 for a year until i come up with some good money to do all that ? nah man, i throw a small turbo on the car, have some fun while im at it, and then later when i could really afford it, i throw in the H22 but built. Im not an N/A person, i like boost and spray... but again, my car is high mileage so i might not even turbo it and get the H as u say and then just save up after i got the motor up but still... lots of things to consider like shop costs, swap time, check engines codes that i cannot afford, between others...

 

BTW.... P_Adams.. i just found a block guard for the H22.... so i guess i dont need to mess with the sleeves or do i still need to ?

DO those of us whom have a clue of what we are talking about... Dont ever post about a boosted motor again as its blatantly obvious you have not 1 clue about what the **** you are talking about.


PSI is IRRELEVENT... HP/TQ are... ALMOST as much as your tune. PIck a power goal and go from there... If you must equate PSI to HP, at least put it in context.

I go:

I made 300 WHP on a stock F22b1 eith 140K on it...

Stock except for headstuds (just precautionary.. planned on going to 400). AT 15-16 PSI on a t3/04e 57 trim with 50 ar comp cover and .63 ex with 880 injectors, 2.5" Charge pipes and downpipe, 3bar MAP, 38mm WG wit BONE stock fuel system (except for injectors (NO PUMP OR ANYTHING) I was using DSM 450s but was running out of fuel around 280 WHP. Im sure a pump woyuld have got me more...

Heres a Dyno sheet of the setup at 6 PSI baseline and 9-10 PSI with a descent tune (not really solid, I bumped up the boost and changed out map sensor, injectors etc)




Weve also made 464WHP on a friends bone stock H22 for over a year, took the kit off and sold the motor and kit to fund an all motor 300+ WHP F project... I myself made 300 WHP on a f22b1 that had 140K on it when I boosted it, I beat the **** out of it for over 30K miles and a year and a half, TRIED to blow it up and all I did was break a ringland on #4.


Is all in the research you dop, the parts you pick and your tune.

The weak point of ANY Honda motor is the ringlands in cast pistons... Rods being next, both of which can be replaced cost effectively. The H will need either MAhles (yuk) or to be sleeved if you want to run forged slugs...


You can run also H rods and custom pistons in the f, but Ive seen fs make 400 whp reliably with only headstuds (although if going for more than 300-350, Id AT LEAST throw pistons at it... for 400+ id do rods too, nice thing is you wont haqve to sleeve it.... Make sure to use a dampner though (no gay *** lightweight UR puklleys and ****)or the bottom end will **** the bed - your bearings wioll show you who is boss. TRUST ME


I myself would throw rods and slugs at the F (which you wont HAVE TO SLEEVE due to the Iron liners in the motor)

A block gaurd is useless on the H... PLENTY of power is to be had on an open deck motor... Im making a good bit over 600WHP/450 TQ on my H.... BUt its fully built... for more than that, whicj is coming...

LMK if you need any info... Ive gone all routes mentioned and would love to help you out... ALthough a H22 rocker, there is a VERY special place in my heart for the F... I dissapointed ALOT of people with the ol SOHC.


By the way... 97 H22A4 are also 50 mm main and not the bigger 55mm like 98 and newer... FYI

Breaking trannys is my problem.
