I am getting done ls2 402 block, G5X3 cam, AFR225 heads, full bolts on, they say 500-510rwhp... so the G5X3 cam needs a stall of 3000-3200 with it, so I am going with 3000. the question, is my stock A4 tranny gonna hold at 500rwhp? has anybody run on that much power with stock A4 and stall and was ok?
FYI:I am looking to build up the tranny eventually in a year or so when I get more money.
I think I would start worrying about that tranny.
hmm, I called LG Motorsports shop here in Wylie TX, and they do tranny build up for $1700 that would hold upto 600rwhp. I think I may invest in that now to be safe. :yup:
Stock 4l60E's are rated to handle 350 ft. lbs. I believe. At any rate, a stock 4l60E is not going to hold up to the motor you are fixing to put in front of it. If you choose to run a stock tranny, its on borrowed time and I hope you do get it upgraded as soon as possible.
I apologize in advance if I am telling you something you already know but didn't see any mention of it. You need to get you a good tranny cooler and I would recommend a shift kit when you have the tranny upgraded as well.
LOL, ya pewter, I didn't want to get into specifics on the trans. I was being a little sarcastic. The 4l60E's had some upgrades as the years went on, with GM trying to improve it each year. But with that kind of power an upgrade on the trans is a good idea. Larry.
I knew what you were doing :yup: :DQuote:

ahhhh $$$$$$$ :shrug: I spent on this torque monster built:
4k new ls2 forged 402 stoker,
1.5k G5X3 cam and springs kit,
2.3k AFR225,
$400 3:73 gears,
$400 3000 stall,
1.7k built A4 tranny
1.5k labor
----------
12k :flex:
You are going to have a sweet setup djvaly! :yup:
What kind of compression are you going to be running?
i agree,do the trans.Quote:

i have a 3000 tci streetfighter for my 224 cam which is a perfect match although slightly bigger wouldnt hurt.
what stall company you want to use?
DJ, i also see you want to supercharge the car, the G5X3 cam isnt the best choice for a blower cam.
you may want to ask the supercharged guys reguarding a cam that would work perfect.
yeah the mechanic there said 3000 stall would be a good match. I'm gonna ask to see if I can bump it up to 3200 or so, I am still on stock 10 bolt so he said he doesn't want to create too much heat in the rear. :shrug:
on the s/c question, I do wanna rethink that I may go with twin turbo setup in a few years... I think 700-750rwhp will be good final setup at low-medium boost
well with full bolts on, ls2 402 motor, AFR225, G5X3, built up A4, 3:73 and stall they said 500-510rwhp... now my next big move I think maybe a twin turbo setup so low boost I say 750rwhp.Quote:

I really agree with the rear end junk that comes stock anymore.
I bought a 1999 Silverado 4x4 ext. cab new and the rear end went out
about two years after I bought it. They bought and installed a used one for me, and I was very glad. (It is a G-80). But even with periodic lube changes the rear end is still weak.
I also thought that cam required more stall than that. Why are you wanting to stay so low on the stall? Why not look at 35-3600?
Your on the right track. Been there done that. When I dropped the 408 Stroker in the GTO the trannie lasted....oh ....about 20 minutes :)
Went ahead and spent the $2900 bucks on a FinishLineTransmissions Stage V 4L65E ( http://finishlinetrans.com/store/pro...products_id=31 ) with a 3600 stall....Vigilante Stall lasted about....oh....another 20 minutes....got a 3500 Yank Pro Stocker stall....and all is good now....
couple of things.....Really think about a trannie cooler with a remote spin on filter.....that spin on filter saved my ass when we ate the Vigilante stall...sum bitch was full of metal....kept it from going into the trannie....the trannie cooler and remote spin on filter is about $150 bucks or less from JEGS and well worth the time and money....I mean you are investing around $2K in the trannie....cheap insurance to insure it operates at peak efficiency and last you....

still on the stock 10 bolt so the mechanic said he don't want too much heat created and 3000 stall should be in the middle. but yeah, money money money ;)
Hey Sarge,
That is great info about the spin-on-filter.
It would be good to have that set-up just for the sake of being able to change the filter and have piece of mind about your tranny.
11:1 compression just like the ls7 motorQuote:

it's ok I can always swap to 3400 or 3600 if I need more stall
but thats going to cost you more money to do it over again.Quote:

email any ls1 tuner, pretend like youre going to buy a ls1 heads cam package and you also want a stall and ask them what they would be a good fit.
I'll call around and see wassup mate, I'll call for some second opinion of a stall with the G5X3 cam which is slightly aggresive.
please do email/call. 3000 is a to small for that cam.Quote:

anything over 400 and sticky tires youre fucked.Quote:

problem is the stock trans wont hold that power either. two of my buddies who post on here have rebuilt there trannies several times and neither is at 450 rwhp.Quote:

I sent the tranny to a tranny special shop to build it to hold to 600rwhp.Quote:

I just blew mine with only 6k on mods i have.....(see below)
They are pretty weak man......only 364rwhp 400rwt here and blew it....
Blew my 3rd and 4th clutches and bands

With the kind of power you are talking about, a rear upgrade is necessary and makes the car much more safe. Loosing an axle at high speed is no fun, and whats worse, is depending on how the rearend breaks, it sometimes will take the transmission with it.
I personally prefer to start modding a 4th gen from the rearend and work myself forward. Larry.
DAMN that car will be smoking people....good shit man:firedevil:Quote:

danm 3000 dollars...performabuilt looks like a good deal to me..1200 dollars and up to 500 rwhp
hughes said this one is good to 1000 hp well see putting in lsx block punched out to 427 with l92 heads and intake :drivin:
:boobies: NICE
waiting on the tranny to get back to LG Motorsports here.. the tranny is being built up to 600rwhp in a shop in Indiana... :toetap:
how much they hitten u for
total so far 15k+ 5k previous = 20k... but I am all new 402 motor, full bolts on, maybe LCA and tq arms left to do :think: that's about it. next a procharger and 12bolt... but a few years. I am getting 17X9.5 and 17x11 new wheels and tires but that's a 1k or so.
I decided to go stage 4 built up A4 tranny, vigilante 3000 stall, 3:73 gears...
with G5X4 cam :woot: and 402 ls2 stroker motor.
check out my photobucket I created today with all the pics @LGM. I will upload videos of my dyno pulls on youtube.com tomorrow, I get errors when uploading videos on photobucket. :think:
