4l80 swap Guys I got a 2002 trans am with about 800 hp single turbo car if that matters, feel like it’s time to make the upgrade. It’s not a race car it’s still got ac. It’s gonna probably go to the track though. My question is what torque converter would be the best for this application? I’m looking at circle d, fti and ptc. I’ve heard good things about all of them. I got enough money to buy this part 1 time.
thanks
thanks

Torque-Converter Selection for a Vehicle like yours:
(A Production Vehicle with original Frame/ Uni-Body, Can be daily driven if chosen, RWD, Forced-Induction Engine Under 1,000HP)
...Should be considered a Highly Critical "Piece of the Puzzle" that is the Power-Train Assembly.
I currently direct any and all 4L80E Inquiries towards @MaroonMonsterLS1 (Grady of Farrer Out Transmissions) as I do not Provide any Services anymore.
He most likely would make one of his Offerings from @jakeshoe (Jake of Jake's Performance Transmissions) as he offers "In House"...
YES, you heard that! In House Torque-Converters (That would have been another Dream of Mine, instead of Calling Chance all of the Time: $$$$$).
My other choice would be:
FTI (as already one of your own Considerations) has been very well received as a Sponsor, Here on this Forum...
And over all has provided Some high Quality Products for the Applications most often used by Members here.
Hopefully Dalton @FTICONVERTERS (If he is still at FTI... It's been a long while) will chime in here and help out.
So I would recommend Jake's Performance or FTI for a 4L80E Build like yous at this time.

Aprilfool: For a build like yours, like Vortec said, details about the truck will be crucial to making sure the converter is properly built for your vehicle. And a good converter can easily "make or break" a car/truck. To start things off below is a list of details I would like to have in order to spec a converter. Jake and his team will likely want the same details so if you haven't called them already, make sure you have the below information for them as well. I'm available via Phone 386-736-5816, e-mail dalton@ftiperformance.com, or PM here on LS1tech. Feel free to reach whichever way is most convenient for you.

I have a FTI Triple disc 2800 in my Impala SS 25k miles so far very pleased with it.

The vendors responding above can probably all make the right converter for you. Many of the same billet parts are available to all of them. I'm not a vendor. I'd pretty much in the same boat as you with comparable HP in a Turbo'd 6.0 cruiser that sees the track. Had a custom converter made by a vendor that has retired. Very drive able 2800 stall with a billet case and ballon plate and great at the track as well. Mine is a single clutch since I only lock up during cruising in 4th gear.
When swapping a 4L80E into an F-body, one must also consider the added expenses in addition to the torque converter.
Flexplate (TCI is a cheap SFI option, or you can go OE)
Dipstick tube - Lokar flexible is OK, Mad Man is much better and doesn't require pumping fluid in. MM-DT 4L80E
Lines to route from the transmission to the cooler - many go flexible 6AN PTFE, cheap Evil Energy kit on Amazon
If you go 6AN lines, you need cooler port adapter fittings that are 6AN. Banjo fittings make it easier dealing with the tunnel in the 4th gen F-body
Yoke that is 32 spline that will fit the 4L80E output shaft - can go chromoly here with strange or Sonnax, some just go OE
4L60E driveshaft can be reused, just need the different Yoke put on. I went aftermarket DS.
4L80E Crossmember - Midwest Chassis, UMI, various options here
Transcooler - Tru Cool 40k OC-4739-1 is the GOAT
4L60E to 4L80E harness - you can buy a cheap one less than $20 on ebay and re-pin it. No need to spend $200 on a harness.
4L80E segment swap using something like HP tuners on your stock ECM, or stand alone transmission controller like the US Shift Quick 4
Figure $1.5-$3k in parts (cost of converter is included in this range) to make it all work right.

Hey I appreciate that. I already bought a bmr crossmember since it’s already got all the bmr suspension.
I was stuck on the cooler lines. Didn’t wanna beat the tunnel up on it.
I got a little experience with hpt.
from my experience it’s the little $20 things that end up costing you.
I was looking on Jake’s website and he has a section about his 4l80 builds about what fluid to use. And he briefly mentions hydraulic oil, does anyone use that and is it beneficial to do?
