How much to build tranny for turbo

[Grant1057]

Hey im wondering how much i would need to upgrade my tranny for a stage 1 trick performance turbo kit. I was thinking roughly 40 pound injectors, and hoping i could keep my stock fuel pump any input is appreciated

750 for stock 4L80, you mod crossmember and wire harness, Pay to tune it.

Dont mod the 60. it a waste.
your going turbo, you WILL turn up the boost.
the 60 Blows under stock conditions.

80 or nuthin..

ive read i have to get modified drive shafts. would i have a custom shop do that so i can keep 4x4? because its a dd and i live in a snowy climate

 

[ezdaar]

find a 4x4 HD, pull shafts..

idk where people get this BS from where its bad to mod the 60e. spend some money and get a proper built unit and it will last. ive had my FLT level 6 65e for almost 2 years now. its got probably 50 mid 12 second 1/4 mile passes on it and tons of street abuse. ive done a few AWD burnouts at the track also. ive seen this same trans run mid 11s probably 100 times in different trucks. even one guy ran 10.8 with a FLT 65e.


edit : keep in mind the 80e is heavier and robs power. it also has a very long first gear so you will need some power to get your truck going

There are modded 60/65's that'll hold 650+hp...not being able to build a 60/65 is a myth.

A few companies, like FLT, specialize in them.

BIG LOL on that one....

we are not on a camaro forum, you have a heavy truck that weighs about 3 camaros. a 4l80e is a must have with the weight of these vehicles. Im making a honest 400+ hp and cant hold a 60e for shit. you want dependability, not 20-30 runs down a track.

I run a 4l80e in my 01 tahoe, with a vmax infront of it, and a 3800 stall converter. and just drove cross country with it, pulling a 85 suburban!!

also remember a 80e is not bullet proff either!! LOL

LOLLL are you serious? learn your facts before filling someones head with useless information. i run the shit out of my truck and it weighs in over 5500 lbs and will run 11s this year. i have probably 100 passes on my 65e. 400 crank hp? funny cause mine probably makes mid 500s and i run a 65e.

ahhh thank you someone who knows what there talking about

 

[ezdaar]

a stage 1 80 will handle all the power that stage 6 60E will and not think twice about it.


theres a drastic price difference between the two.

Facts are fact: fact of the matter a 60e is a weakling. Take a poll. Count experiences not just yours

I am dead serious. Take it from one who has owned over 5 SUVs that are heavier than your truck. 4l60e is a car tranny designed by GM. GM also designed a tranny for a truck. It's called a 4l80e! That's why they put a warranty behind it.

I broke too many built 4l60s and with a junkyard 80e it can hold more power than a so called built 5 or 6 level 60e.

I'm not trying to lie to someone or even stupider convince someone their 60e hold behind a turbo. Lol

If 1 or 2 people getaway with a 60e, it's luck. It's a numbers game. I rather know that 50 people who run junkyard 80e that outperform a 2000$ so called built level 10 4l60.

It's physics power and weight. Simple. I broke too many of them. Heck they were designed to hold less than 410 ft lbs of tq.

Better yet build a built 80e and let 1500hp rip to the wheels and be reliable somewhat.
Sorry but too many people fall into the build it right crap. It takes about 8 times after a failed 60e to finally say I'm going to give a 80e a shot??

I much rather reliability and the loss of a few hp.

I'd rather have a built level 6 65e than a stock 80e anyday

several have blown level 6 & 7 4l60es in vehicles that weigh a lot loss than yours. IMO a LEVEL 1 or 2 4l80e will do you better.

A stock 80e with a simply shift kit is good to hold 650hp. I mean you can always build it up from there.

I personally don't care if I do have a warranty on a 2000$ tranny if it brakes. Its like the cheap parts at a auto store that come with lifetime warranties. Do your rather replace a part 10 times as it has a life time warranty? or would you pay double to triple the price for the durability of a good part, that has only a 2 yr warranty, and requires you to never swap out the part any time soon.

to the original poster, I would not hesitate to do the swap to a 80e. You will get way better answers to your question on www.performancetrucks.net < they have experience.

dude you keep going on about weight and other crap information again. weight does play a role but it has been proven a 65e built properly can handle serious power. personally id recommended the 80e to someone with a 12.0 - 11 sec daily driver truck but anything slower than that i dont see the point. lifetime warranties are for cheap parts??? FLT offers lifetime warranties on there trans and i can safely say there far from cheap parts. and you keep talking about people blowing up transmissions can i ask what shop they had them built by? ive heard probably 30 stories about trans builders who build transmissions for race cars that handle 1000 horse bla bla bla and they blow up 1 week later in someones street driven truck. go with a reputable company and it will last just as long as an 80e. you've owned 5 gm trucks well ive owned 4 trucks and a camaro and im only 21. i have experience also and im on pt.net and silveradoss.com also.


for example this truck. he is my tuner and i know him personally very well. hes had his FLT 65e for years behind 2 different setups and it went 10.8 in the 1/4. i know another truck with a forged 370 and a TVS 2300 running a FLT 65e trans also. his truck went 11.5 before the new motor

Im getting that the stage 1 80 is a good option but will also rob power and i would imagine gas mileage. Does anyone know how much an 80e swap actually costs for misc parts not the tranny itself, i know there are threads about it but it never seems to answer my question. i know you need a wiring adapter or harness, tune, drive shafts. and past that im lost. would the costs of installing a junkyard 80 be more than getting a built 65e?

would you choose the performabuilt level 2 60e or the flt level 5 60e. sorry for noob questions here

im not sure on the cost but i know you need a different driveshaft, different crossmember, torque converter, wiring, and tuning. im probably missing a few things here and there. if your going with a built 65 go with FLT

 

[brucebruce45]

Still saying lvl 6 65 over 80

 

[1fatho]

http://www.finishlinetrans.com/transmissions/index.htm

4L65/70E-5 Extreme Duty – Level 5 $2,295.00

4L80E-4 Street Strip – Level 4 $2,195.00

 

[Grant1057]

^ That doesnt account for new crossmember, drive shafts, wiring harness, tune, flexplate, spacers, bolts, or transfer case...

The transmissions in both the Tahoe and the SSS held up very well, with a ton of boost behind them. These are big trucks no matter how you look at it, but a properly built transmission should hold.

The SSS now has a level 5 65e with 650+hp, no problems. The 80s are a different animal, and many don't like the shifting patterns when going from a 60/65.

Hoe, are you running NA or FI?

 

[hoe]

Jenna bear I am runing Na. With plans of boost from a turbo or procharger. Truck runs great no lag or nothing people describe, but I do have a 3700 stall. I like the swap. Also like the whine from it too. The 80e is louder for sure, but sounds good.
