5 SPeed : Do-Able... easiest way is to find a junker that no longer needs his ECU, Pedals Etc.. and Tranny of course... it's not cheap figure...$3000 - $5000 if you're not doing the labor... maybe more...

6 Speed : Very Expensive, custum 6 SPeed from Trust / Greddy, or maybe Knight Sport (I don't remember, either way a japanese part only..) I belive.... $7k for the tranny alone... + $2k-$3k for install swap of pedals etc....

3000-5000 to swap in a stock manual transmission? Are you high?

And 3K for pedals for the HKS dogbox?

You should be able to swap over a perfect condition manual tranny with everything including a new clutch for well under 2000 if you can do the work yourself, add 600-700 if you can't.

The HKS box isn't exactly a street unit, and it is ~7 grand, but you're not likely to spend 3000 on any magic pedals and installation. Hell, I'll install either of them for you for 1000 labor any day.

We've had this discussion before.... If you're not willing to do your own fab work, and mechanical labor, no I'm not High, if you are willing to do it, Yes I Am

$2000 + $1000 for labor is still $3K... and if you consider that I'm in California, where anything is more $$ than most places in the U.S. other than N.Y. then $3k-$5 is in the ballpark... = Not High....

Just because you do all your own fabrication / labor, doesn't mean Everybody else does as well... some of us have Jobs that pay more than what a mechanic would get, and therefore choose to spend our time working that gig instead of working on a car...

Also not everybody has such an idealistic outlook on life, meaning, that if the syncro's are bad (Common on 5 speeds) you're looking at a couple hundred to get the tranny fixed, and if you break stuff, due to inexperience, or misfortune... more...

I strongly disagree with these people who come on here telling others they got a rebuild for $1500, **** the gasket kit alone is close to a Grand... maybe my figures aren't as optimistic, but if you budget that much you won't be left with a half finished project, and can take the leftover $$ and do something else with it...
I have nothing to gain by posting "higher" price, I don't own a shop, I don't recommend them, and I don't profit from them in any way.

And I recall seeing a 6 Speed, go for 7K on E-Bay.... and I was shocked as well... !!!

Wow 7k for just a 6 speed tranny! Thats just crazy. For 7,000 you could bolt in a LS1 with a T56 6 speed and if you did it yourself have some money left over if your careful parts shopping. I would drive it like it is for now ...since its prime sports car weather. Decide for yourself if the car needs any sort of mods in the wintertime.

What fabrication is there to put a Mazda 5 speed and related assemblies in a car that had them as an option exactly? It's an unbolt this and bolt this in ordeal.

I'm not trying to be difficult, just curious here.

The fact that there is no hole / bracket for the clutch, I'm not certain about the slave cylinder, and then if you want to tie it into the Cruise controll or anything else throttle/clutch related you'll have issues

All I'm saying is it's not simple, there is some cutting welding, and piecing together, that you can't do with a set of mechanics tools... it's not like a tourque brace, strut tower, or what people call "Bolt On's".

As I understand it there are no provisions made for the pedal assembly, and I've heard from more than one Rotary Mechanic that the pain involved with the swap is not worth the $$ they can charge for the time in labor... and that they generally do this for long standing / repeat custumers only....

Then again there was a place in Nor-Cal, that was saying they do them all the time, and it's no big deal...

I looked at it a while back after I wrecked my first FD, and wanted to see if I could use a Auto FD as a good base to build off of, and it was more $$ than I would have saved in purchasing an Auto FD, so maybe my prices are a bit dated 2-3 years, but in my experience things rarely get cheaper over time.... given that nothing changes to deteriorate its value (as in putting miles on a car)

I gotcha. So apparently it's far worse then the FC, which is a bolt in affair. Still, that much labor is pretty ridiculous. I'll swap an LS1/T56 into an FD for less then 2000 in labor, any day. I'm pretty sure a manual tranny is less involved.
