H22 or turbo F22?

[MRX]

I only planned on posting a tiny bit in this thread but the reliability factor is negliable in alot of our instances seeing as the h22 owners tend to push their motors harder and higher than the f22's do. If you have an arguement for either side consider this
Turbo F's blown:
skinnye
91accordexR33
theone
iamanonymous

H22's blown:
2point6 (he in fact is not on his first motor)
Dr. Loveskudang
Aero3685 (fading fast)
MDIZZLE4SHIZZLE

those are just ones right off the top of my head. And plenty of ppl have blown stock f22's here. ALOT of reliability is how much you push the car and how far you'll take it with the revs. I use my power when racing and every now and again to simply pass traffic. But the only time you'll ever catch me over 6k is when i'm whoopin' up on somebody. And i'll often back down from races...

don't worry...i do not take offense. as long as you are providing good feedback as to proving me wrong or right. i want someone to prove me wrong. so i don't have to question what i do. and like i said...i do like the h22 but as far as reliability like mrx said...they have good examples of both failing.
but you can't use clutches as an extra cost because most people will upgrade there clutch anyways. not all but if you are really concerned about reliability you will do it eventually

i've made my decision, but keep it up guys...i like this discussion...

It's a good discussion. There really is no proof either way, so nobody can really be proven right or wrong.

Antoine (MRX) you REALLY know your motor in terms of tuning. Someone with your knowledge and foresight (and restraint!) would certainly get the most reliability out of just about any setup. You don't push your car too hard, and you know exactly what it's capable of. You plan ahead when tuning so you don't damage anything. That makes your setup more reliable than a high-revving NA setup, I would say. However, there are MANY people out there that aren't as thorough as you. They don't bother to learn as much (myself included... ) and they don't plan their setups as well. They will have more potential for things going wrong (blazen_accord comes to mind there... he cared, but he trusted a shop, rather than learning everything himself... boom.) People who are less inclined to learn the mundane details are definitely better off with a stock-ish swap. IMO, I don't think pushing an H22 to 7200 occasionally would do much damage. If you take the rev limiter off, THEN you're pushing things... but stock components, well maintained, pushed to the factory limits should be fine.

I use the clutch and axles in my arguments simply because they wear MUCH faster with turbo. The amount of torque put down by a turbo motor is greater than the stock components (especially older ones) are prepared to handle. Yes, they're great things to upgrade anyway, but with a simple swap, they aren't necessary.


In the end, it comes down to preference. I personally would trust my H22 for reliability. I'm half expecting to blow up my F22 when I boost it! I don't intend to, but I won't be surprised if I do. (and if I do, I'm planning a DOHC frankenstein motor to replace it )

i may just go with a h22 myself, but was just making and trying to prove my stand on it. what i actually wouldn't mind doing is doing the h22 swap with an auto and swapping the f22 into a civic or crx and then turbo it. strictly race car of course.

H22+auto tranny=why waste the time necessary to do the swap in the first place??

[deevergote]

H22 auto isn't really that bad. He explained his lack of desire to swap the tranny in another thread... Accordtunerx was running an auto H22 for a while, and it was ok. I messed around with him on the highway once, and he wasn't noticably slower than me... and my car is lighter, and my motor slightly more modified (at the time)!

the auto mainly just suffers from more drivetrain loss. also because the h22 doesn't have low end the initial take off is slower. but i believe that once you get into vtec the only difference is drivetrain loss...maybe 5 or so hp. i don't know that if it shifts out of vtec when it shifts gears but it shouldn't be to far off from it.

unless you're saying that a h22 auto is only as fast as a f22 auto?

i was tlakin drivetrain loss and slow shifts...plus manual takes off quicker unless you run an auto with a stall converter

[85gts]

if a manual stock h22 swap will run a 14.8 or 9 then i would say the manual is good for atleast a 15.3. which is a lot faster than a f22 auto.

[deevergote]

I've seen 15.6-16.1 from an H22 auto in the past. I'm sure if you upgrade the auto tranny, you could make it a bit more effective.

[85gts]

so if i use a f22 auto tranny...it wouldn't even be much faster than a regular f22 auto?

what? the *same thing here* wouldnt be much faster than *same thing here*

[85gts]

i mean a h22 with an f22 tranny wouldn't be much faster than a f22 with an auto. even though there is a 50-60hp difference?

[JaiBeezy DnB]

Im no pro but i think what will happen is that the f22 auto is a longer gear ratio so a stock h22 will be out of vtec, but i believe the h22 is still powerful so you will be faster than a auto f22 with your h22 with f22auto. I believe that the f22auto is weak or that it it may not be able to transfer as much power effectively than a manual or h22 trans. Im getting a headache well i hope im clear if not well sorry :P
