From the same guy that brought you the LS1 batmobile.

Full build thread hereSome background first. I purchased syclone 1060 back in March of this year. When i first got the trck i really wanted to do a 6 speed swap because i really like 6 speeds. I soon realized that i wanted to make the truck really fast in a staight line and a 6 speed is not going to do that. Then i wanted to do vortec heads and a big turbo but didnt want to drop $2500 on a build 700r4. So i said i would do a 4L80E. Until i did some research and realized how big of a rip off it is to do that swap.
Now to the present. My goal at the end has always been to run i the 10's. I didnt care how i got there, but i wanted to keep it streetable for daily use. So having LS powered cars before i decided that that was the best choice for speed and reliability. After alot of research i made a game plan.
-LQ4/4L80E
-tc78 turbnetics turbo
-60lb injectors
-front mount intercooler
-2bar speed density tune
-arp rod bolts
-custom made headers by me
-modified stock oil pan by me
-motor/trans mounts by me
-3600 stall converter
-custom build wiring harness by me
I will be keeping a complete log of every dime i spend. I am going to prove that you make a syty reliable and super fast without dropping 15k. I will be doing everything myself except for the tune. I will make everything that i can and buy only what i have too. There is alot to buy so i will list it as i get it. right now i am shooting for 550whp. I will see how far that gets me at the track and go from there.
Here are some rules i am going to stick to. Keep A/C. Keep AWD. Do this as cheap as possible but do not compromise on safety. Run in the 10's and drive home on pump gas.
Here is the truck
