H22A and S tranny. - Honda Prelude Forum

kennethmina · 05-31-2003, 03:39 PM

I know this has been covered before but I still can't find a exact answer I want. Or maybe I don't know how to search the rigth thread.

Anyway, I am almost crazy to get a H22A for my lude but not enough money to do the whole swap.

So, I have decided maybe just to get the long block with ECU of course. and keep using my S tranny.

Now, my question is how much slower will the S tranny cause me? If I shift at redline every gear, is it still gonna fall off the VTEC range? I know S tranny saves gas.. hehehe... I don't race everyday anyway... so, can I still get a smooth VTEC range all the way while shift at redline? Or, even if I shift at redline it will still fall off the VTEC range.

Please advice you technical experts!!!

Thanks alot.. like I said, anybody wanna donate me some money for H22A swap? your name will be on my car!!! good deal?

sorry man, it'll drop out. I think the H23 trans is cutting it really close, but that it still stays in vtec... the F22 trans is just too freaking long.

Definately you will drop out in 1-2 shift, most likely 2-3 but 3-4 should be ok. If you lower your engagement point via Vtec controller you might not be too bad. The motor any way you look at it will be a big improvement. So i say get the motor. Im running the si tranny still. I never ran the f22 tranny. You can drive that till you get a good deal or save the money for a vtec tranny.

But on the good side, you will have more vtec in each gear. ha.

my h23 is just close enough for me not to get a h22 tranny. dont get the S man...u need the shorter gears.

kennethmina · 05-31-2003, 10:32 PM

it is a bad news to me.

But anyway, I guess I will maybe just drop in a H22A longblock. Although it is not perfect but at least I can experience the improvement step by step. And when I got the VTEC tranny then I can be the one who tell the difference!!!

But i still need to get a job before I can do a swap.

Kenneth,

I am currently running the h22a jdm vtec motor with the s tranny. I did this because I bought a long block to do the swap. NEways the thing is tall but it can be dealt with. I can stay in Vtec between 1-2 with my VAFC. You gotta run 1st out forever and get a quick shift and you make back into Vtec. 2-3 does drop out for a brief second. I believe 3-4 is the same way. I too am going to be getting a h22 tranny soon. But for now I am rebuilding my engine. So to make a long story short it can be bolted up directly, I think my car is pretty quick with it but I know it will be quicker with the h22 tranny. peace

I can get a used Si tranny for fairly cheap...

PM if your interested, I think he's looking at 300-400 shipped, I will have to talk with my mechanic.

My friend has a JDM H22 with an S tranny and his best time at the track with i/h was a 15.1

kennethmina · 06-06-2003, 12:34 AM

hmm.. 15.1 is not too bad. How about with VTEC tranny and same setup?

I guess I will do it as soon as I found a job.

but yeah, I really hope to find out the 1/4 time for VTEC motor with S, Si, and VTEC tranny. and compare the difference. It will be interesting. and from there we may come out with some new ideas.

xratedSH · 06-06-2003, 12:58 AM

I have a vtec and I have a hard enough time keeping the car in vtec during the 1-2 shift(have to quickshift at 7700 indicated on the stock tach), so I can't even imagine what it would take on an Si or even worse an S tranny.

Oh, also I notice that I lose about .2 on my times that I drop out of vtec in the 1/4.

save money for the swap and get a vtec tranny, do it right the 1st time! swapping trannies is not that easy

i have a friend that has a jdm h22 in his acura cl....he is using the f22/23 tranny (prelude s tranny) his best 1/4 mile time all motor was 14.7 @95.6 mph completely stock

Cool swap, make sense too, bolts right in.

Red4WS · 06-06-2003, 02:27 PM

So what times are people getting in there jdm h22 and Tranny? Also what elevation?

Satan_SRV · 06-06-2003, 02:30 PM

you guys have to realize that the S tranny gating isn't too bad, like they are similiar to the H22 and H23 in rpm points. The main drawback is the 4.062 final drive, which cause your actual top speeds in every gear to be much higher. So when you shift it's not too bad, it's mostly the length of time you spend in the gear.
