I'm planning for a LS_/T56 swap. My car is currently auto, so I am wondering what pedals would be the best to go with? Find some 3rd gen pedals, or go with the pedals come with T56 from the 4th Gen donors?

 

I got 3rd gen pedals myself, found a good deal locally. They may be the same, if they are not, well, that could be a big headache down the road.

you will still need to drill a hole for the master cylinder, but thats not too hard. Have fun!!

 

Search this out. I believe someone maybe MrDude had issues with the pedals. Something about the pin placement providing too much or too little of a stroke to the master? Dont remember much more than that but I'm running third gen pedals although yet to drive the LS1 M6 I ran them for years on an LT1 style t56 with no troubles.

 

Yeah, I was remembering something similar. I think that the pivot points are different or something like that on the LS1 T56s. I think there was too much...or not. Can't really remember.
I know that the LS1 (and maybe LT1) pedal assemblies are two pieces while the 3rd gen ones are 1 piece.

 

There is a difference between the LS1 and LT1/T5 clutch master cylinder. The LS1/LT1 pedals are one piece with the gas pedal attached, and the 3rd gen's are two piece with a seperate gas pedal. I'm running the 4th gen pedals with no problems other than like MrDude had, I have a set of LS1 pedals which the clutch pedal doesn't come out as far as the LT1 pedals do in the 3rd gen cars.

 

I used LS1 pedals. The more or less bolt right in...I cut the gas pedal off and re-used my stock 3rd gen gas pedal. Lining up the master cylinder for the clutch is kind of a pain...but it will be no matter hiwch set of pedals you use. I also used the 4th gen brake booster and master cylinder. So I had no issues with it all bolting up. Just take your time, and keep mocking things into place and double checking everything.

So, it's pretty much according to which master cylinder I go with? Would there be any disatvantage to using either?

 

If you are going put the LS1 in, you need to use the LS1 clutch master cylinder. There are differences in where the lug where the clutch rod from the cylinder mounts and if you use the LT1 or 3rd gen pedals, you may not get enough travel to let the clutch disengage all the way. Using the LS1 pedals in mine doesn't keep the clutch from disengaging but it doesn't stick past the brake pedal, it's about in the same position as the brake pedal.

 

So if you have an LS1, you need to use the LS1 MC and pedals? Hmm, I have the LS1 MC, but I have 3rd gen pedals. I am going to have clutch disengaugement problems?

 

Klortho hit it on the head. I was posting a similar response last night when my computer decided to freak out. Anyway... if you are doing the LS1/T56 swap, you have no choice but to use the LS1 master cylinder.

You CAN use either set of pedals. However no matter which set you use it will take a bit of tweaking.

3rd gen pedals... will bolt right in, and fit good. However as mentioned above, you will have to change the point on the clutch pedal where the master cylinder attaches. Kind of a pain if you ask me.

4th gen pedals... will bolt in for the most part. They take alittle bit of fiddling to get them to fit good...but they'll fit. I recommend cuttingoff the gas pedal on the 4th gen pedals. And just use your 3rd gen gas pedal. The travel will be good to go with the 4th gen pedals...but getting the master cylinder in and sitting in a good way is a bit of a pain. I still feel that its easier than modifying the mount point on the pedal though.

Let us know if you have any other questions!

Awesome. Good info guys. Thanks for the help.

 

How do you modify the attatchment point??
Does it go up, down, forward or back??

 

Well I dont know for sure... I believe it has to move up...and towards the rear of the car... But I cant say for sure because I used 4th gen pedals. Do a search for "4th gen pedals" or look at the T56 swap threads. Plenty of info and pics on how guys modified their pedals to work.

Someone that's done it, or remembers for sure what has to be done will probably chime in and shead some light...

I had to use 4th gen pedals for my T56 swap because of the adjustable master cyl i used. It would not fit on the third gen stud only the 4th gen.

I cut off the gas pedal, and had to enlargen the holes to fit the third gen mounting bolts.
