Do I need the H22a tranny for a F swap?

[preludude]

Do you really need to the compete drivetrain for a H22a swap? This guy did using the F22a tranny and axles.

they are the same tranny with diffrent gears! If you are going all motor go with the h22's tranny! If you plan on boosting go with the f22's tranny!

 

[cointelpro]

i didnt know you could use an h series tranny with an f series engine...

 

[lude68]

me either....i was always told they didnt bolt up?!?!? :unsure:

 

[tab]

They bolt up, I drive one every day. No problems so far.

 

[Accordturbo94]

Yep they are the exact same!

 

[preludude]

Would there be a difference then in performance? I wouldn't think so right? Maybe the ratios would be different?

shorter gearing f22 is a lower power motor.. h22 is higher..

from a manufact. stand point you want a motor with tall gearing for high top speed for the lude

and the f22 a shorter gearing to get up to speed faster with since it has less power..

you wont have a super high top speed but shorter gearing to get up to speed faster.. matched with the power of the h22 power plant.. yada yada

 

[preludude]

So...from what you're saying, that the f22a's tranny might get you faster 0-60 times as opposed to overall top speed?

This is not correct. The F22 tranny has longer gears for fuel economy. The H22 tranny has shorter gears for better accel.

Yeah that is correct.. thats why turbos are better on the f22 and non turbo use the h22!! You can stay in boost longer on the f22 cause you wont be shifting so soon! the boost makes up for the gear basically

 

[preludude]

Ah, I see, that explains alot. When I drove the H22a, those Rpm's shot up like a rocket...My f2 takes forever to get those Rpm's up to speed.

my f22 tranny sucks balls it wasn't made for any type of extra stress stick with the h22 tranny all the way.

If what you are trying to say is that the F22 tranny has longer gears (I think this is the point you are making but I can't tell) then you are simpy repeating what I said which is the opposite of what mdlax1 said. The F22 tranny has much longer gears than the H22 tranny. Your argument about boost doesn't make any sense.

I know the F2 wasn't designed for high levels of boost, but what about just 200 or so hp? Should be fine right? Thats what I was trying to get to. The engine itself is alot less expensive than the whole set with tranny together. And If i'm not trying to race this thing to death, but to have a faster engine, then the trannys not going to blow to smithereens right? As long as it doesn't compromise performance...

The F22 tranny will probably slow you down. You are most likely going to drop out of the power band at every shift.

Go H22 unless you boost, F22 is long geared.
