Is the $600 difference in cost better spent on something else? or is the 4.9 worth the money over the JDM 4.7?

 

IMO yes it's worth every penny. But if your one of those squemish about the RPM's on the highway go for the JDM 4.7

 

buddy has a 4.9 and he loves. not as bad as i had expected to be, even on the freeway, but then again i already run a 4.7. in any case, 4.9 will make up for our torque-less wonders!

verdict says: GET IT

Hey Chuck, this is Greg (SpoonEK9) from JDMUniverse! I've been wondering the same thing about it. Where can I get the 4.9 at? I definitely want to go with that, b/c I really won't do any freeway driving.

What would be interesting to see is a compairison of the differences in acceleration of the 4.7 verses the 4.9. Does anybody have a vid like this?

 

someone on here once said, the 4.9 made 5th feel like 3rd. true statement?

Depends. What RPM your currently at. Let's just say to make a pass on the highway you no longer have to down shift.

 

Had I stayed N/A I was seriously considering the ATS F/D.

depends on what tranny FD you start with. If you have a ITR/B16 4.4 tranny the 4.78 is a nice upgrade. If you have a 4.78 the 4.9 is only about 200-300rpm different

 

4.9 is wayyyyy better if you want it more agressive.

 

I have the 4.9 and I'll never go back

 

i know this is probably archived, but since the thread is here who cares

anyone know the top MPH of the ATS 4.9 in 5th, and the MPH in 5th VTEC engages?? i'm currently running my crossover point at 6000 RPM, just curious to an approximate number, i know answers are going to varry a little bit

 

Integra Type R U.S. spec & Civic Si with ATS 4.929
RPM Gear Final Km/h Mile/h

1st 8,000 3.2310 4.9290 55.36 34.41
2nd 8,000 2.1050 4.9290 84.98 52.82
3rd 8,000 1.4580 4.9290 122.69 76.25
4th 8,000 1.1070 4.9290 161.59 100.43
5th 8,000 0.8480 4.9290 210.95 131.10

Looks like 131mph @ 8K

 

nice, this is my next upgrade

On the dyno, I think I hit 143 or so.

Here's a vid, the 5th gear pull is somewhere in there. You can pick out the speed for both redline and VTEC, but keep in mind the stock tach is off a bit. 8500 fuel cut/5700vtec, stock ITR ecu.

could an average joe with good workshop install a new FD?

i have never looked inside a gearbox before but i really want a ATS kit either 4,9 or 5,077

With the Helms manual and some common sense, sure can. It's not to hard. Just do like I do and every bracket or part you take off, make sure you put the bolts/nuts with it and put it somewhere. This way you won't end up with extra or missing parts during the job.

 

ATS FD - best mod I ever had besides in car camera

 

its really not that huge of a difference on a 4.78 tranny.
my 4.9 is only about 200-300rpm different than my friends stock 4.78
But to the 4.9's defense it sure did feel well at Streets of Willow
