I have both the 3.7 FD and transgo, also came from the 3.5 FD. I can tell you going from 3.5 to 3.7 is noticeable and was worth it to me. Personally I think 4.08 may be a little too short.

 

hmm do you have any vids of launches with your current set up so i can see how much shorter the 3.7 is to the 3.5

or did you already have that set up when you and Jayk did the exhaust vids theres plenty of launches in there

 

+1, i would love to see that launch in motion

 

This is an older video back when I was N/A, its from inside the car but maybe you can tell the difference in RPMs. 1:00 - 2:00 is me

 

just a tad shorter and i think thats what i want, paired with the the transgo seems like its pretty strong

yup junk yard run this weekend see what i can find

 

^I didn't have the Transgo kit at that time but it is definitely a mod worth getting.

 

Something isn't right because everything I've read (including infinitihelp.com) states the following for the 1st gen car:

5AT RWD sedan/coupe, all years (3.36 gear)
5AT AWD sedan, all years (3.54 gear)
6MT RWD sedan/coupe, all years (3.54 gear)

My friend just bought an 07 coupe, 5AT rwd with the sport package. I confirmed it has the 3.36 gear. It was a simple comparison of steady cruise rpms at 80mph, torque converter locked vs my 03 sedan with the 3.54 gear at the same mph and considering the fact that I have about .6" shorter rear tires.

 

That is odd. My car was completely stock when I bought it. The differential was certainly a VLSD and I sold it to a member on here who originally had a 3.3 in an 03/04 5AT, he noticed the taller gearing when he installed it.

Silencer_0 had the same thing.

 

I have a 07 5at sport coupe infinitihelp says 3.5

My 5th gear 80mph rpms are at 3500 (oem rays 225/40; 245/40)

 

I sold my 3.5 to a friend that already had the 3.5, but his was open diff and wanted my LSD. He noticed no change in gearing. And I bought my car with 7400 miles on it, so I highly doubt someone changed out the pumpkin prior to my purchase.

Yeah I had the 3.7 in that video, it's the last video I made lol.

 

nice, you should make a new one

0-60 or 40-100 or whatever you like and have the camera only on the RPM gauge

did it feel like driving a new car?

 

man its so hard to find these pumpkins for reasonable prices with vlsd

 

I wouldn't say it was like a new car, but the quicker acceleration was definitely noticeable. One of the best mods IMO.

 

yeah i will probably agree with you on that soon in the future

 

I agree and I will add with a tune and exhaust it made a world of difference in my sedan. I drive a 5AT and at 30 can punch it and break the tires free with new tires on.
