So not only did I find an LS2 with 65,000 miles on it for 2K but I also found a T56 with 16,000 miles on it for $1,700. What would I need to do to not only mate those 2 together but how hard is it to get the hydraulics hooked up to the trans, master cylinder and clutch pedal installed on my currently automatic '68 firebird? The trans doesn't come with anything except the transmission and shifter. Is there a way to get that trans installed without going hydraulic? Any help would be greatly appreciated. Thanks!

The 2 will mate together easily if it's an LSX style trans. Your best bet is going to be hydraulic. You'll spend almost as much to use a manual linkage from what I've seen. Great price on the motor, little strong on the trans w/o the bellhousing, as it can be tough to find a good used one. There are several choices to choose from if you go hydraulic. What did the T56 come out of? U said your automatic car has a clutch pedal, I'm guessing it used to be a manual car & the pedal was not changed? In the past I have used stock 1st gen pedals w/ATS firewall bracket & replacement rod end for the master. I used a 98-02 master & slave cyl. It's not that difficult but the price does add up. Add a clutch & bell housing to the list and you are probably looking at $800-$1000 +/- depending on the parts selected.

My car does not have the clutch pedal, the trans does have the bellhousing. It's coming from a 240 sx ls1 swap. Would it be cheaper to buy a hydraulic master cylinder from tick or an oem replacement? Is putting the flex, pressure plate, clutch, throw out bearing ect. An easy job or should I have it done at a shop since I've never done it?

I think the tick is more $ than GM part. Be sure to get the firewall bracket that goes with the tick master. We tried to use one with the ATS bracket & it didnt fit. As far as doing it yourself, its not that difficult if you are mechanically inclined. If you decide to have a shop do it, I'd make sure they have experience with the swap, or at least you trust them and their work.

No you need to use a hydraulic set up and it's no big deal to put one together. This is what I used. http://www.summitracing.com/parts/wil-260-5920/overview/

5000 miles on the build and no problems.

Good prices on the parts for sure. Be sure the T56 you found is an LS1 not a LT1. Hope the build goes well for you.
