Scored a 6262 jb turbo for $100 along with a roller cam. I’ll be finishing my engine with ported heads and a different converter. I have a friend with a 2800 stall lockup. I’m already blowing through my ancient Vigilante 3200 stall at 24psi with my blown te62, barely drops 300rpm on shifts at wot. Single disc so I can’t wot lock it. Is a 2800 stall enough for a .63 ar housing on a 6262? Thanks for any input. Mods in signature with the addition of a 212/212 roller cam and cnc champion iron heads and this 6262 and e85

Think you should be looking at a 3200 non lock up for that combination
Maybe a 9.5” PTC 17 blade ?
 
I ran a 2800 AC non lock with my 6262 JB...but I know how to tune. Most will need a 3200. Most LU's slip like a whore unlocked...hence why guys were always wondering why my MPH was better than theirs.

I’m a good tuner. I may look into a non lock. Any mods needed to run a non lock converter?
 
What's the combo. in the car now that you are wanting to use the new 6262 with?
My Vigilante 0 pump 3K stall dropped 475 rpm on the 1-2 shift racing, locking it in 3rd gear around 85mph dropped approx. 700 rpm.
RWHP at about 400.

Forged pistons. Stock crank and rods. ARP main studs and rod bolts (line honed). Roller 212/212 cam. This new 6262 turbo, champion cnc iron heads. Champion ported intake. E85. I’m blowing through my vig 3200 and it’s a single disk, not made to lock at wot.
 
when you say it drops 300 on the 2-3 shift, what RPM is it shifting at?

Yes. Talk to a trusted 200 builder. it's not much. The TC is the most important piece of the puzzle. Most fuck it up.
 
The stock short block can handle bottom 10's all day with zero KR. Bison will tell you the same. Eventually the stock piston will crack across the top of the piston along the piston pin. The worry is this. The more you bore the block...the closer you get to the water jackets. I picked up a used .030 over short block from a local and cracked into the water jackets twice and sleeved it...and the third time it cracked a cylinder to the top of the block and I had to scrap the block. No one beat on these blocks more than I did so I know their weaknesses.

I believe I've told you this on more than one occasion and that is that you already have a good torque converter it just needs to be modified by Dave. The torque converter will act pretty much like it does now during normal driving but when you go to full throttle it will couple so much better it will scare you.

The answer is yes, that is plenty converter for that turbo. I run a 210/215 hydraulic roller with a 6266 precision turbo, the same heads you have however I am running Harland Sharp Roller Rockers with a 1:65 ratio which brings my lift to 587. (yes i did the math). I run a 3200 stall converter and it is absolutely amazing. Mid to low tens on 32psi of boost at 7lb launches. Be sure to get some upgraded rocker arm because the shaft on the stock set will break if you bounce it off the rev limiter, ask me how I know!, You'll be fine and if you dont like it you can have your 3200 converter rebuilt and it should be perfect even if you go a little bigger on the turbo, not much bigger but a little bigger. Make sure you keep the lock up converter, you WILL regret it if you go non lock up. I've had my car 13yrs and have over 700 man hours in it so you can trust me. Also, if your running a vacuum booster on you brakes you will want to get the hydrobooster for the 1984 grand national set up. Once you start making a lot of boost you WILL rupture the diaphram in the vacuum booster, again, ask me how i know. It is no fun finding that out at the top of the track going 120 mph. feel free to call me and Im happy to give any advice that may help you. 210-531-6443. You can see my car on tic tok at reneortiz128. Call me I dont mind at all. Good Luck. Oh, I almost forgot, make sure your chip locks the converter at WOT......HUGE DIFFERENCE. I ran the above mentioned set up with my 5831E precision turbo and of course the turbo was to small so it only made 16-18lbs on a good day but it ran 12 flat at 117mph and 11.88 at 119mph. You can see it on You Tube running a mustang 5.0 with a paxton supercharger and I ran a 12.04 at 117mph, I launched it at 5lbs through the mufflers. Just go to You Tube and search Grand National runs low 12s, my video says my name on the video, Rene Ortiz. San Antonio Raceway.

So. I should look into getting the converter rebuilt to couple better at wot?
 
I will have a fully redone valvetrain in that new motor too. Just need to find lifters and rockers. Have a 212/212 cam. Mine shifts at 5400 ish. Pretty high for a stock cam but. Not sure how to fix that without a different converter.
