It is rated at 700 pounds of torque.

I actually have an RPM transmission in my tbss. And that blew a few months ago haha. I knew they were reputable for 4l70s and the like, but didnt know about the t56.

And I dont know much about the tr 6060 so cant really help you there. Heard you have to do a little bit of fab work to make the shifter fit correctly though.

[ultimateracing335i]

No the the magnum comes in different configurations. I'll send the link

Ahh ok I see. I think a rebuilt t56 would still be cheaper for me versus the magnum. Im pretty far from making that decision anyways, so not really worried about it yet.

[ultimateracing335i]

For sure it would. I'm in Canada so I cand find t56 transmissions as easy as you. To import a used one doesn't make sense. Now I have warranty.

I started a thread. A few pics of my build.

Posted a few questions yesterday that got buried. Hoping someone has answers.

Anyone know where you can buy predetermined lengths of brake hardline as well as fittings, or fittings already connected?

Also, anyone have a part number or a place to buy a 2 outlet 17/17mm MC. Im having trouble finding one.

You want OE or custom?

OE lines aren't that expensive, and they are listed in mm on BMWFans and RealOEM.

I've gotten lines from Fisher and Napa for custom projects, pre-flared with fittings. Usually sell it in 1"-8" lengths, IIRC. Napa can probably just make custom lengths too.

[CLM21]

If napa will make me some pre-flared with fittings that would be awesome... and theyre all gonna be custom lengths/bends.

[CLM21]

Well, I was able to get some brake hardline at napa today, and ordered some fittings online. Was also able to find a 17/17mm MC from a VW rabbit, which should be getting here one Friday hopefully. So I should be getting the entire brake system done this week. I guess Ill take pictures in case anyone is wondering how I did the abs delete... I guess its not documented very well?

[CLM21]

Finally got the top of the engine ordered today... exciting. Engine specs:

Short block:
-LS3 416 CID
-Manley 4340 4.0” stroke crankshaft 58x
-Lunati 6.125” H beam rods w/ ARP 2000 7/16” bolts
-Mahle forged 4.070” NA pistons w/ multi fit valve pockets (-4cc)
-Mahle piston rings & pins
-Clevite H series main & rod bearings
-Dura Bond one piece cam bearings

-TFS 255 GENX Heads
-Custom camshaft
-Fast LSXR Intake Manifold

Can't wait to get this thing completely put together.

What kind of WHP numbers are you shooting for? Looks like a good pile of parts!

[CLM21]

Dont really have a goal, just wanted to build a mean engine. I'm assuming the whp to be somewhere in the mid 500s hopefully.

Ought to be a little bit of a handful! And a heck of a lot of fun!

My stock LS1 will smoke 2nd easy with 255s in my truck, I can't picture it with my 225s in the 30:puppy:
