ok so today i went out to the dragons tail and some other twisties with the GA fiero club. Going out there made me realize that a 5spd may be better for running out there and ther over all drive down the highway as well. I may be able to get a good deal on a 5spd getrag. So, that said, i am doing a 3800SC for my fiero and it should be geting put it VERY soon. Should i keep the 4spd muncie that i currently have or would the 5spd getrag, overall, be beter in the long run? Down the road i plan to save up the money and install an F23 because i know they are nice and beefy transmitions. Just would like a good few opinions on what you guys would do in the same situation.

p.s. if it makes a difference 1. it will be daily driven to work where i usualy dont go over around 65MPH and 2. iv never been one to do any clutch dumping. Only time i get agressive is twisty roads sometimes a light to light every now and then.

3800SC + 5sp getrag Great for hwy and good holding power for that eng. (What I run )

BUT if you want fun in the curves...4sp

Neither will hold up to tons of abuse, so noo speed racer unless you streghten the trans

I will say no to your clutch, because IF it is not a Spec III / Clutchnet or better the clutch will not hold the power of the 3800sc

I have the 4spd and it works great for holding up the power. Gas mileage suffers on the highway, revs are way too high. When it burns a hole in your pocket, it makes things a little less fun.

Don't quote me on this... but I think some clutches can be used from the 5spd on the 4spd but not the other way around. However, you may need the 4spd throw out bearing regardless of where you get your clutch from. Again, don't quote me on that, but I remember something like that being discussed a while back when I was having my swap done. My Spec clutch came from a 5spd getrag.

Good luck!

ok so then what ill probably do is stick with my 4spd for a little while and either sorce the parts i need to do the 5spd swap and/or save the money to do a full F23 swap in the end because it is a better trans overall. Just have to get the money to do it all lol

p.s. a buddy of mine said for overall stength the 5spd is the best for a 3800SC is that correct because iv herd the 4spd is the best...And would any tranms shop be able to strenghten either of those trans?

IMO 4 speed Muncie for drag use and light street /highway.
5 speed for street /highway all around use.
As previously stated neither will hold up that long to the WOT power of the 3800SC. I know many guys who have blown up these transmissions but in all honesty most of them drive like animals. Its more fun that way.

Clutches, as far as I know, are physically interchangeable, but use different T/O bearings for the 4 and 5 speed. I have used a clutch for a getrag 5 speed in my 4 speed car.

Some 4speed pressure plates are too thick to use with the 5spd. Make sure you take some precise measurements.

The 5 speed is better for freeway driving, however, the Muncie is stronger and has better gearing if you do most of your driving around town. Given the expense of switching cables, etc. etc., I'd run the Muncie for a while and see how it works out.

Yeah this is what i was thinking about doing. I currently do mostly hwy driving to work and all but, 1. it really isnt for that long and even though its hwy most of it is in traffic and i usually don't go anything over around 60 or 65 at most. and 2. most of the time i drive pretty smoothly rather than aggressive im a person that likes to play it safe first...unless im out on the mountain roads >.< But, my long term plan is to try and get the money to put an F23 swap in. Overall iv added up to around $1000 for that swap. Which is around $150 for the trans from the yard, $390 for friend of yours shifter adapert and mounts, then a good clutch by spec that can take a goo bit of torque. So overall the 4spd will be the best to hold me off till i can get the money then?

The clutch problem is that the hole through the pressure plate fingers is a different diameter depending on the throwout bearing being used. You can probably use the smaller hole in the Muncy PP for the Isuzu or one with a larger hole but not the other way. Best thing is to go with what is proper. Larry
