Hello all. It's been awhile since I built an ls engine but I'm starting to gather parts.
Vehicle is an 05 Cadillac Escalade esv with the LQ9, awd. All stock with just a efi live tune.
Looking at the speed engineering twin turbo kit, hand ported stock heads, tbss intake with ls3 gold 90mm throttle body, tsp stage 3 turbo cam 218/224 .600/.600 113+3, double springs, ls7 lifters, 7.395 pushrods, 80# injectors, dual walbro 450 pumps, -8an feed, stock line for the return, performabuilt 4l80e transmission, circle d converter (not sure on size or stall speed yet)

Goals for it is a fun daily driver/family hauler. Around 600hp to the wheels. The only track around me is only a 1/8mi so I doubt I'll ever take it there.
How does my list look, anything else I should do instead?

 

Is there a reason your set on twins over a single? For that power level it won’t take much.

 

Mainly for looks. The speed engineering kit is right in line cost wise with most other single kits. Seen several dynos and a lq4 with a 224 cam at 5 psi made close to 500. 600 was just a ball park number. Dont want to chance bending a rod until I can afford the next stage which would be a forged rotating assembly then would aim for the 800-900awhp

 

The Lq9 has the stronger rods, you’ll be fine unless you crank the boost or mess up the tune. You get what you pay for.

 

Havent seen anything negative about the speed engineering kits. But then again it hasn't been on the market for very long. They use dual 64mm turbos. Not sure on the exhaust side other than it has a .84 AR. I'm tuning it myself with efi live. Will most likely be a sd tune like my last truck with a custom os. Itll be a fairly conservative tune. And I forgot to list it but I will have a water/meth kit to help keep the iat in check.

 

I don't see a reason to swap intakes or throttle body on a turbo setup when it's not an all out build. That is just more money for parts that aren't required. The stock intake and throttle body will not stop it from making 500-700hp without a care in the world.

 

Okay. How is the cam choice? For the converter I dont really want to go over 3k rpm and I dont want to shift over 6500rpms. With the 227/235 113 cam in my old lq4 I had to shift around 6900rpm which ended up causing it to spin a rod bearing which took out the motor.

 

I have a BW S465/83 1.0ar with a t4 flange on my Cummins that I'm swapping out with something bigger. If I got the hot pipes from someone like trick turbos would I be able to use it on the Escalade? I can push about 45psi on my 6.7 Cummins at around 2200rpm. New plan for the Escalade is a dd'able 550-600hp

 

thats a fairly large housing on the turbine. Your cam choice is perfectly fine for a mild build, but the turbos are a hell of a lot more capable than a mild build haha.

 

Lol. Okay. I keep seeing guys putting a s480 on there trucks so I wasnt sure. Would swapping a .9 ar housing make it and better? I know itll help with spool up. Have a wastegate setup to run 10-12psi or so.
