Looking to turbo my current truck. It has lm7 motor 233 239 .600" lift 112 lsa cam, new springs and 7.400 pushrods. ​​​​​​i have twin 78 75 vs racing turbos. I'm looking to see what others would suggest for 1. internals (crank rods pistons cam) 2. heads. I plan on going full forged but unsure of companies to use. I have the 4l80 also but it needs built, not sure who to have build it. Thanks

 

Twin 78/75s is quite the turbo selection for a 5.3.
what are your goals first

 

What converter do you have currently and what will you put in the 4L80?
233/239 at .600 is quite the cam on a 5.3 lol

 

I wasnt going there yet haha..
We have a 408 with a smaller cam and smaller 71mm turbos. its quite a handful and turbos light off pretty fast, its gone 5.6s in the 1/8th on low boost.

Hopefully he wants to go with a larger cubic inch since he has those turbos.

 

1200 to 1500hp every now and then criuse night truck to strip later on

 

I currently have a 2800-3000 don't remember brand right away in a 4l60 that was fully billet blew it 5 times. So changing route and just building for what I've been wanting.

Whatever is needed needed to the power goals. Not sure of what to put in it or where to send it.

 

​​​​​​​I wouldn't mind stepping up to bigger cubic just not sure what to pair with the twins

 

1500 is a lot of sauce😳

 

****, mine makes me sweat bullets at 900 crank. At 1500 there is almost zero chance of it ever hooking up. Lol...

 

You sure you want this for a driver?
