My Evo RS gearbox sucks for drag racing can I put an FD on it?
I dont want to swap everything out on it because it would just be really expensive.
1st gear is really short and I want to do an FP Black. Currently running an HTA71 and it runs out of steam quickly on a 2.3 stroker kit.
A friend is giving me his 4.11 FD free since he got a 4.3
Would this combo work? Or am I running out of gears because the HTA71 is just too small for a 2.3?

Wanted to post about my experience with having a 2.4L and 4.11 gear in my personal RS ( which I sold years ago). @ things to note. I did enjoy the lower freeway cruise RPM it provided. I was not buzzing around @ over 3K when driving 65 mph. Also having the lower numeric gear allowed the engine to pull the torque better then the stock gearing. Having a FP green (original version) provided an impressive torque spike that was short lived but the 4.11 FD provided some dwell in the short torque band area to "pull" the gear. On the street it was a blast. I was tuned on E-85 and I personally liked running the 4.11. 1st gear was a bit tricky but the 2.4L pulls you off the line better then a 2.0L would. If I kept the car I would have liked to install a BBK B -BB which is produced by another company now.

I never understood when people say they like taller gearing because they "stay in boost longer". If by staying in boost longer, they mean it takes them longer to get through a gear, resulting in being slower, than yeah. It does that. 
OP: the post above is correct. Your turbo is what's running out of steam. That's fine, if you are looking for response and instant torque. A car doesn't have to pull all the way to redline to be fun. Personally, I bet your setup is a kick in the *** to drive.
The taller final drive is only useful if you are trying to not shift into 5th gear at the race track. With your added displacement, you probably wouldn't even be slowed down enough, by the taller gearing, to really notice.
That's quite a bit of trouble to go through to drag race a "rally car", though. Are you sure you want to go through all that to shave a few tenths off a quarter mile time?

There is a point where too tall might be a problem but in the case of my setup it did not make the car any slower. If you have ever seen dyno curves in 4th gear as opposed to 3rd gear you notice the gear loading put more of a fullness in the curve. Also you do not have to be as exact in your shift points because you are not flying through the sweet spot so fast.
Hopefully you begin to understand why I said it. Drag racing is drag racing and a couple tenths may beat your opponent.
Yes the Evo was designed as a rally car but it does many venues well. So use them and enjoy.

seems like we have similar set ups
My car just feels like a Honda Civic Type R.....goes through gears quickly

In the case of those that go to taller gearing in an Evo to focus on drag racing, it's always because not having to bouncing off the rev limiter or hitting 5th gear makes up for the slower acceleration. I've never heard anyone say the car accelerated faster, but I could be wrong.
As for why people take Evos and make them into drag cars? I won't get started on that topic

Oh, you got this! I did 11.7 while rolling off the starting line like a stop sign LOL. You can definitely do low 11s. I did all that with a stock 6spd, street disk clutch, and pretty much everything else OEM. Oh.. and baby Greddy cams LOL

I ran the HTA71 at like 18 psi for a while with stock intake box.

Those Greddy cams were free..But probably not worth the time it took to swap them. I now have S1s and really like them. I like cars that are torquey and responsive, though (I'm back on stock turbo with possibility of another hta71, in the future). My dyno sheet doesn't impress anyone.

Yes, more of a "fullness" because the car is accelerating slower, giving the turbo time to spool. Just because you see peak boost sooner and longer, doesn't necessarily mean you are going faster. I guess it comes down to trial and error for your particular application.
In the case of those that go to taller gearing in an Evo to focus on drag racing, it's always because not having to bouncing off the rev limiter or hitting 5th gear makes up for the slower acceleration. I've never heard anyone say the car accelerated faster, but I could be wrong.

Fullness because the gear loading helps produce/develope more boost and torque. The torque "pulls" the gear and the car covers ground. Have you ever raced a Z06 corvette that has a broad first and second gear? Same principle since they made similar 470 ft/lbs of torque as I did. I could hang easily with them if I got offline well.
If I didn't it was a loss for me. If using the stock gearing as we have stated already you have to be too perfect. 4.11's gave me more an advantage. I knew if I could hang or beat out a 2011 Z06 I wasn't slow by any stretch of the imagination.
