Choosing a stall

[Low Impedance]

By july i want to be putting in a higher stall converter. Ill have my shift kit and IPT clutch kit in by april (due to nessecity). Ill will be running a T4 GT40 w/ the .95 a/r. On the big side, yes, BUT i got it for a steal. I think a higher stall and a step will spool it no problem. But its not going on until i get some more pieces to this puzzle. But after reading several threads, i have developed some questions that i need answered.

1. Should i run a double-stacked flexplate?
2. what stall would be best in spooling the turbo but compromising at the ragged edge of streetable?
3. would a 2-step be a worthwhile addtion to assist spooling this turbo.

Go with the highest stall possible in your price range. Something in the 5000rpm range would be good. Double flex plate is a good idea as none of the sfi plates are out yet make sure they are tig welded together

Go with a stall around 4000-4500 and double stack the flex plates and tack weld the bolts that connect them to the torque converter.

just curious what would be the benefits of the 4k- 4.5k stall compared to a 5k stall ... like on your setup for example.

reason im askin is...

i plan on running

2.3
gt4294
fp3 camshaft or 280s (not sure as of yet)
ipt 9.5" billet converter w/ multidisk lockup converter
ipt full trans

in my '96 gsx. . . just tryin to get more ideas to make it more 'driveable' or 'streetable'

On my car the stall is at about 4200 and I drive it on the street all the time and love it, and on the track it obviously has worked well, i dont know much about torque converters and what exactly is the best setup but im sticking with 4200... from what I have experienced I would think that if you got a 5k stall torque converter it would Maybe good at the line but when driving around or going down the track your rpms would be at 5k minimum the whole time.

yeah i was taking into consideration your times with driveability too . seeing how i plan on going the same size turbo on 2.3l also i'll probably go like that with 4200 stall. i know my stock converter i was able to stall up to 3k rpm before on 14b which was 20psi heh good times. cant wait to feel the new setup once finished and running.

also being your a 2g not a 1g like most all the other posts i've read. actually i can think of 1 other 2g... but that helps out alot with deciding also. thanks again.
