[Syty] 700r4 trans

[DOlivares]

Sure... "somewhat larger" should be fine, depending on what kind of LAUNCH you're trying to achieve... and how much extra gasoline you're willing to buy if you DON'T...
  a.. drive around town in Overdrive, and
  b.. drive around town a lot above 42mph.
Not to mention the extra HEAT a high-stall TC will contribute when NOT driving in OD... and assuming you haven't disabled your TCC-- good for performance, bad for heat and gas mileage!

High-stalls on the street are for kids-- much like Trix (silly Rabbit!)-- and why I opted for something under 3000rpm when I ordered my Vigilante, whose primary selling point for me was its grippy, 4x clutch area.  I wanted extra insurance that the TCC would stay locked up in spite of assorted hiccups from the motor... wanted the good gas economy above 42mph.

So unless you're building a track-only bracket machine or like harsh TCC-lock-ups, don't sweat the stall speed so much.  If you are trying to smoke tires to the exclusion of much else, MATCH your stall speed to the torque peak (rpm) you've already matched your cam and intake velocity to jointly achieve....

  Thanks D.O. for your suggestions. Will the 2800 stall TC be good enough for a somewhat larger turbo in the future like a PTE setup?

    I don't know why the Camaro version of the 700R4 would be mechanically different from the version in your Ty.  All I did to mine was...
      a.. Swap-out the TC for a Vigilante, stall = 2800rpm; 
      b.. B&M Shift-Kit (made absolutely no difference!); 
      c.. Swap-out the Pan for a deeper, air-tubed version from Derale; 
      d.. Replace all fluid with RedLine Racing Fluid; 
      e..  and fresh K&N Filter (internal... never neglect this!) 
    No more plans till I get time to beef-up the engine more.  Transmission issues are closed for the moment... dead-reliable status already achieved!

      I got a few quick questions for everybody. My friend has a 1991 Camaro
      and he's willing to sell me his 700r4 trans for like a $100. Is there
      any difference between that trans and the stock one in my 1993 Ty? If
      not, any recommendations on what upgrades to do to it (please specify
      brand names) like what torque convertor company to use and is a 3000
      stall ok, what shift kit should I use, and what trans cooler should I
      use? My Ty is pretty much stock except for minor mods like setting
      timing to 0, AFPR, re-routed intercooler lines (removing the metal lines
      for hoses), Ultimate chip, Walbro HP pump, scan tool, cap/rotor, Iridium
      NGK plugs, 8.5mm wires, etc. My Ty has 104,400 miles on it, ran best of
      13.36 @ 101 mph, 1.8? 60'. stock turbo @ 18 psi on 93 octane with a
      little knock at full throttle (not sure if false because of the
      upshifts), fuel pressure @ 54 with vac line off, 32 lb lucas green
      stripe injectors. Any and all help welcome. Hope this will create a
      little discussion out there. Thanks again.
