Would it be possible to swap the stock Accent 5 Speed with a Tib. 6 speed? Would it even help to get a 6 speed for the Accent? If not that thenhow would I get a 6 speed?:ermm:

Anything can be done with enough $, I think it would cost way to much to make it work.

what is your purpose of a 6 speed? What are you trying to do as a goal?

I thought by changing it from a 5 to a 6 speed it would help boosts it's acc. and speed a bit. Just a thought I had and thought to ask.

The 6 speed tranny for the Tiburon is called the MFA60.

http://www.aichikikai.co.jp/english/mission.html

However in order to bolt this to an alpha or beta (which use the m5af3 and mfbf2 accordingly), i think you would have to swap the bell housing off of the alpha or beta trans. onto the MFA60. With all this said the final gear in the MFA60 here is two low for any stock beta and ANY alpha motor.

Here's the gear ratios...

M5AF3 1.5L(A) 1st:3.462 2nd:2.053 3rd:1.370 4th:1.031 5th:0.838 R:3.250 FGR:3.942
M5AF3 1.5L(L) 1st:3.615 2nd:2.053 3rd:1.370 4th:0.971 5th:0.825 R:3.250 FGR:3.650
M5AF3 1.6L(L) 1st:3.615 2nd:2.053 3rd:1.370 4th:1.031 5th:0.825 R:3.250 FGR:3.842
M5BF1 1.6L(J) 1st:3.083 2nd:1.947 3rd:1.285 4th:0.935 5th:0.756 R:3.083 FGR:4.592
M5BF1 1.8L(J) 1st:3.462 2nd:1.950 3rd:1.393 4th:1.061 5th:0.878 R:3.250 FGR:3.650
M5BF1 1.8L(R) 1st:3.462 2nd:1.950 3rd:1.393 4th:1.061 5th:0.878 R:3.250 FGR:3.650
M5BF1 2.0L(R) 1st:3.462 2nd:1.950 3rd:1.393 4th:1.031 5th:0.825 R:3.250 FGR:3.650
M5BF1 2.0L(J) 1st:3.462 2nd:1.950 3rd:1.393 4th:1.061 5th:0.878 R:3.250 FGR:3.650
M5BF2 2.0L(G) 1st:3.462 2nd:2.053 3rd:1.393 4th:1.061 5th:0.837 R:3.250 FGR:4.056
M5BF2 2.0L(D) 1st:3.615 2nd:2.053 3rd:1.393 4th:1.061 5th:0.837 R:3.250 FGR:3.650
M5GF1 2.7L(T) 1st:3.231 2nd:1.952 3rd:1.296 4th:0.943 5th:0.775 R:3.455 FGR:4.063
MFA60 2.0L(K) 1st:3.153 2nd:1.944 3rd:1.333 4th:1.055 5th:0.857 6th:0.704 R:3.005 FGR:4.678
MFA60 2.7L(G) 1st:3.153 2nd:1.944 3rd:1.333 4th:1.055 5th:0.857 6th:0.704 R:3.005 FGR:4.428

A:X3 Accent L:LC/LC2 Accent J:J2 Elantra D:XD Elantra R:RD2 Tiburon G:GK Tiburon K:Korean Tiburon

Notice the MFA60 made for the beta overseas has a higher FGR. This is because of the increased amounts of torque from the beta to the delta. This setup would probably only be acceptable for a turbo/supercharged beta.

The quickest setup in terms of off the line acceleration with the accent is to mate a GK Tiburon tranny with a 4.667 FGR kit from kspec.com onto it.

Last thing, The MFA60 used with the V6 tib. is considered relatively weak compared to the MFA60 used in the Nissan Sentra SE-R.

unfornately not. But i'm almost sure it would since both the I-4 and V6 trannys are MFA60's. I'm going around later today to various dealerships with my digi cam to find out.

So basicly with a stock 1.6L Alpha Accent engine this would be pointless. In order to make it work i would need to swap the engine AND modify the trans.?...Correct?

Basically, yeah. The main thing thing to understand that close ratio transmissions (6 speeds) main benefit is getting power out of a motor with a narrow power band. Almost all hyundai motors are not this type of motor.

Hyundai motors kinda work against the norm of an import motor eg. honda/toyota/nissan
Most import motors are high revving, low torque, oversquare motors with fairly mid to narrow powerbands up high. These motors benifit from more tight(close-ratio) gears because there is less drop in rpm between gears which holds the motor within it's powerband.

Hyundai motors, like domestics, are normally low revving, torquey, undersquare motors with wide to mid powerbands. These motors benefit from fewer wider gears to take advantage of the torque the motor makes throughout it's wide powerband.

So it's kinda like comparing a formula 1 engine (powerband from 11,000rpm to 14,000rpm) to a Stroked drag motor (powerband from 3,500rpm to 9,500+rpm). It would be completely worthless to put the 8 gear sequential shift trans. from the F1 onto the Drag motor which is happy with a 2 gear power glide trans.
