Tranny for boost

[91kid]

I'm getting ready to start my boosted h22 build shooting for 300+ whp

And am wondering about transmissions..

Which tranny would be the best for my planned setup, h22,h23,f22?
I don't know if I want to spring for an oem LSD or if its not worth it and I should just get an aftermarket LSD installed ?

How much power is any factory trans gonna take?

Thanks

This topic has been covered plenty of times but im going to chime in since noone else has. Okay the first thing off for topspeed which I doubt youll get to that speed you would use the f22. For the quartermile you would want to use the h22 to get you into your powerband quicker. You would also have to let us know your setup of what you completely to even consider its worth.

You're going to need a good clutch, that's the first thing. I would recommend a cc twin disk if you plan on doing the 1/4 mile. You will also maybe want some good synchros. If you are really looking for something good but expensive a Saenz gear set would be great. As for the LSD its not a must, I pulled a 1.78 60ft time with a non LSD tranny, don't know how much better it would have been with and lsd installed

I know the difference between h and f, I'm just looking to figure which one is better for a boosted setup

And im telling you if your going for top speed go for the f22 if your going for quartermiles and drag racing go for the h22 because it helps you get into your powerband quicker.

Why just a twindisk for just 300whp. A heavyduty street/strip should do him good.

Sorry about the wrong section,

My only concern with the f22 trans is shifting and the motor falling in and out of vtec, with forced induction won't the constant cam changeover wreak havoc on the tune/motor itself?

Also 300 is a baseline, I'm hoping for more like 4-500,
god knows the block will take it

H series will be best, you will also need to consider what size tires you will be useing as that will change your mph in each gear as well.

for 300hp oem trans is sufficient w/ proper clutch and fly. money would be best spent on an LSD add-on and proper ( i stress PROPER ) turbo.

if you want extreme build then i know for sure one ( if not a few by now ) preludepower member(s) got some strait cut gears made and had a very extensive set up.

Check it out though if your going to have it put the f22 transmission get it rebuilt by gearspeed. I would go with the h22 transmission. trust me if your going that fast if you have a 11.5 flywheel you wont fall out trust me.

When you get it tuned you can have the vtec set a lil lower than oem so u won't fall out of it...from wat I understand vtec works off of oil pressure. As long as u maintain that level of pressure to activate the tech system u won't fall out...

Now I nooooo some1 will correct me cuz I'm prolly wrong. But if I'm wrong ill suck it up and learn learn learn. This community is about helping. Not bashing. I have 5 k posts, still don't no all like I should.

vtec is oil pressure operated, I have done a lot of tuning of these motors N/A and you can play with the engagement point a bit, but every set of cams has a sweet spot. where they make good smooth power

Here's the best set up:
-quaife LSD
-cc twin disk clutch
-synchrotech synchros
-Saenz gearset

Total cost: approx $5000
