Now I know this sounds ridiculous but here's my story. I have been having tranny problems since I bought my tiburon and for some reason, I still love and want the car. I have gone through the clutch drama and replaced the flywheel and clutch with aftermarket parts, therefore voiding my drivetrain warranty. This is now turning around to bite me in the *** because the "harmless" oil leak that the hyundai tech said I had (but don't have in writing) was actually a broken axle seal spilling out gear oil. I drove my dry gearbox for quite a while without knowledge of this and now I need to replace it...So...I bought a used 5SPD transmission from the junkyard for $500. not bad huh? too good to be true. I looked up the VIN through HMA parts and sure enough, they sold me a ****ing 6SPD. So now, i don't know what to do because I need to fix my car and I cannot find a used 5SPD. Does anyone know how insane a conversion would be? I don't think I have ever read about it being done.
5SPD to 6SPD Conversion

Isn't there some ECU issues with this transition also, because I don't think it's that simple. I had a chance to get a 6spd and didn't follow through because of all the issues.

nope, sorry guys, think about it.
why can a 3.5 sigma motor (standard auto trim) be converted on a Stock ECU and engine harness, once ur using a manual (gears) it doesnt matter how many you have as long as you have fuel spark and rpms then car will go that fast, the ECU does not know the difference from 1 gear to the next, it cant, its electronic signal, not manual, think about it....

dont listen to these people. do the 6 spd conversion. depending on what performance mods you are going to do to your car the 5 speed will break easier. 6 spd = nearly unbreakable

I got my 5spd tranny from a junkyard in MA. I can't remember what the yard was called,
but it only cost $180 with 14k on it. Try looking on www.carparts.com
It was from a base elantra, so now my gear ratios are a little different. The gears are slightly
longer. I cruise at 3000rpm in 5th at 70mph. I think it used to be 3400 or 3500rpm.
Although it hurts acceleration a little, it gives me a higher top speed potential and the torque
from my turbo makes up for the longer gears in acceleration.

what i think might work is to rebuild the 5 speed using the 6 speed gears use all of the gears that u can. it will lower your top speed by a little but u should get better acceleration for drag racing i heard of someone doing that on seoulfulracing i think

is this true? I'm trading in my 03 6spd for a 05 5spd this month. I figure if your boosted its better to have 5 speed so your first two gears aren't useless. So is it worse to have the 5 speed due to risk of it breaking? that just doesn't sound right to me....

Its total BS.
NGM has a 400whp+ turbo 5spd with no issues. I have NEVER heard of anyone having problems with 5 speeds. 5 speeds are NOT weaker in any way what-so-ever.

i have blown ...
2nd gear once..
3rd gear twice..
and 5th gear once..
with my Elantra i4 5spd t4 turbo..350whp 376tq
many korean tuners have blown 5spd tranny...
i am not saying it's bad but not strong enough to last long time. it's well known fact in korea.
6spd is almost same as.. Evo's 6spd.. damn it's strong tranny..
it is designed and made by ISIN : eisin(might spelled them wrong) who made the EVO's 6 spd
you are so lucky to get 6 spd tranny for that price.
if you are selling it let me know..
