Default upgrading the T5

I got a 351w pushing way to hard for these T5's that I keep chewin' up. Any suggestions on what to do. I drive it about 4 days a week, so I was thinking about a toploader, but I do need the overdrive. I was thinking about T56 or TKO. I don't really know how much work is involved.
Any ideas from people that have done this?

Skip the toploader.

A tremec 500 would be a drop in replacement. The 600 uses a differant input and ouput shaft, and would require a new clutch disc and drive shaft yoke. If you go that route, contact Mike Forte at FortesParts.com. He can get you everything you need. Prices are good, and service is better.

If you're beating it up on the road course, contact Gordon Levy at LevyRacing.com. He can build you a T5 that will match your purpose and last forever.

I'm not sure what kind of car you're running, or what gears or tires (tires are like a replaceable fuse!) you have...but I ran a T5z behind a 500hp+ N/A 347, in a 10.70 2850lb daily driver Mustang for two years without issue. The z spec T5's are rated slightly higher than a standard unit, but not enough to make that much of a difference.

I guess what I'm saying is...rather than blame the 351...possibly you might consider how you're driving/shifting it? That's no insult!! An aftermarket shifter with positive stops (Pro 5.0) is an absolute necessity. Upgraded shift forks are also very much recommended. Additionally, no matter how 'hard' you drive it...you always have to keep in mind what you're shifting. Crisp, 'well aimed' shifts that aren't over powered do more for the life of a T5 than any single internal improvement. I mean, if I could run 10.70's with one behind a 347...it's clear they'll take hard shifts and a good bit of abuse =D.

Hope that helps!!

Cris

Keep in mind, neither the TKO nor the T56 will fit under your tunnel without some sort of modification. You'll either have to hack up the tunnel or use a drop crossmember. If you do the latter, you'll need to account for the change in transmission output angle compared to pinion angle. You can probably get away with using Ron Morris adjustable motor mounts to drop the engine as well, fixing the angle problem.
