Yo. I ave reading these posts lately and I have come to figure that the best engine to boost is the F22. Which is the engine I have in my car right now (1990 Honda Accord EX). Is that right?

Well if it is, I might just save my money instead of swapping the H22 with a turbo, and just rebuild my current engine. Would that be a good idea?

When you say "rebuild" does that only constitue as changing the pistons, rods, and resleeving? What else goes into rebuilding? My engine isn't in too good of shape now.

Are there any manufacturers that make a turbo for the F22? Or do I have to get a custom one?

Are there any other modification besides muffler that I should do to take full affect of the turbo?

Thanks!!

 

My friend you are about to embark on a journey, a VERY expensive journey. If you are a mechanic, or have some other way of off-setting the labor costs, it might be worth doing, but it's still gonna cost ya. I have a 94 Accord with the F22B2 engine and I was thinking about the same thing. With all the research I've done, I think you'd be better off either swapping engines, or building the F22 and leaving it be. As often mentioned, the F22 engine was not designed for performance. As a result, the after market support is lacking. You can turbo the F22, but to get the type of numbers your after, you're going to have to run a significant ammount of boost.

I like the sig line I saw recently: Cheap, Reliable, Performance.....Pick any two.

I've decided to build the F22 engine, and wait until I buy another vehicle to make my Accord fly.

 

You really have no clue do you?

 

Please do some research. Start from the beginning of the Accord forum and just start reading.

 

Actually I am a mechanic. And I will be doing all of my own work, as I have done it beofre on several different cars and trucks. I am very new to the import seen though. I don't know the types of engine, nore do I know the engine numbers. I know what upgrades and things of the like do to the engine. I know all this. I was just looking for some answers. It's alright though.

And to answer your question: Yes, yes I do.

 

I think 94Accord was referring to the waskally wabbit...

 

Sorry all420 I was referring to the person who replied after you.

 

Maybe not. My background is in Nuclear Engineering, not Automotive Mechanics. In my neck of the woods, the H22 swap is a $4-5K proposition, as is building the F22(sleeves, pistons,rods,head work,etc.). Of the turbo kits available, the FMAX kit gets high marks for the F22 application, but at $3700-3800 without installation costs. Then there's the engine/fuel management elctronics and associated tuning costs. Any way you look at it, it sounds like a $10K+ project. Unfortunately, reliability is a concern as I drive 22-25K miles per year. Of the many threads I have searched(yes, I know how to use the search function ), I see many problems encountered.

I approached the original post from my perspective; relying on the information provided. If he is capable of doing the work himself, it's a whole different ballgame.

Not everyone on this forum has the vast knowledge and experience, as well as the abilities that some of you have, but most of us have an opinion. That opinion, right or wrong, is what we are here to express; derogatory comments aside.

 

Anything's possible - none of our honda engines were designed for boost, but people have been *charging normally N/A engines for a while. The best thing you can do is do your own research. Read Read Read. Listen to what everyone has to say and then form your own opinions. Most of the stuff you hear will be total BS while one talks from his/her ***, but occasionally you come across some good info.

Other than that, I wouldn't say that the F22 is the best honda engine to boost, but I feel it is a pretty good platform to work with. The main reason I went with it was its simplicity. I'm going to be boosting an engine that wasn't designed to do so, so I want simplicity. I don't want to deal with mulitple cams and VTEC - that'll just add to the equation. If you want to tackle the more complicated equation, be my guest.

One of the main reasons people may say the H22 is a better platform could have to do with head flow. It's got bigger valves and is designed to flow more air through it. With that being said, there's no reason why you can't increase the head flow through the F22 head. Sky's the limit.

I've seen mildly modded turbo'd f22's run mid 13's (with full interior and street tires). Justin Izumi in Hawaii has run 11's on his heavily modified 91 Accord.

Good luck

 

I personally think the f22 is one of the best/safest motors to turbo of the Honda motors. It has a low compression ratio (8.8:1) and the largest/strongest rods of any of the other honda 4cyl motors.

 

built f22 with turbo would probably be more feasable. whoever thinks the f22 cannnot make some decent power is crazy.

 

oh and what was the part about nuclear engineering? your background from what, like 3-5 pages of your science book... .

how you cannot figure out the mechanics of a honda is crazy.

 

You are not alone in your turbo search. Check out the AccordinglyDone.com forums, there is some interesting info in the FI forum. I am not going to turbo mine anymore, but I was plannign on a DSM setup. I wouldnt run more than 7-8 PSI without a full rebuilt, but if you rebuilt it, opened up the head some, "the skys the limit"

 

Hey twkdCD595, from your profile I can see that your all of twenty years old; you don't even know what a career is yet. I was referring to my professional background. While I am capable of doing considerably more than changing my own oil, I am not a mechanic and do not have the skill necessary to rebuild engines. I realize that there are people on this board that do have that level of ability, and I'm just trying to learn what I can.

How about giving us old guys a break.

 

well, Whats your goals ? However much hp/tq gain your looking for should determine your decision, in my opinion you should boost the f22. A rebuild would be custom ( pistons, rods...etc ) thats going to be a pretty chunk of change to spend on and not get the numbers you want. If you really wanna boost you might have to go custom as well ( i dont think theres a kit made for the f22a4/6 )...you could put a project together and be boosting on your car for less than 2k easy ( minus dyno time and provided you dont go over 8 psi ) from what i've learned on here the f22 is indeed an acceptable start off point with promising possibilities. Reliability is taken care of as long as you boost the right way first. H22 swap can be the same amount of money spent as a rebuild or turbo ( custom turbo could easily be cheaper ) and it has it's reliability factor in the bag as it being a stock engine.. but hey theres always build + turbo with money saved overtime, with that you can pretty much boost your brains out. My advice, SEARCH extensively on this project ( on this site as well as the net ), it's the only way your going to come to a decision. There are some people boosting the f22 on here as well as N/A, look at their numbers, compare your goals with their results and pick your way to fly...GOOD LUCK !

cliffnotes: find what you want, compare contrast engines/plans thru search, have fun

 

i guess so but what is the fun in that...
