Custom Turbo Build Help V6 LLT - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

KFranklin11 · 10-27-2015, 03:05 PM

Hello guys, I have a 2011 Camaro v6 LLT and I want to do a custom turbo setup. Would twins be better or one large turbo? I want to build it from scratch so what all is needed? Where should I get started from? What are the piping dimensions if I want to mount the turbo(s) to the exhaust header? Any and all help is greatly appreciated.

I am trying to do precisely the same thing as you, however I have discovered the most efficient turbo is a 60mm precision turbo. That is what hellion's turbo kit reccomends for their "upgraded turbo". I want a single turbo right where the driver side exhaust manifold is there is a gap there. Hopefully big enough for a turbo.

Smaller twins is better. Too much to scavenge with a really large turbo. Youll be getting in to boost like 4k rpms with larger snail.

On a side note. Fabberge makes a set. Im sure you can see their dimensions on their site.

I'm selling my custom twin turbo uppipes to fit most t3 flanged turbos, 300 shipped, 500 shipped with two tial 38mm wastegates., heres my classified ad http://www.camaro5.com/forums/showthread.php?t=415848: Look in my profile for pics of the pipes. Also have a turbowerx exa pump for the oil return.

I've attempted or built just about every FI setup for the LLT, I have a parts list with estimated prices for the twin system and remote single rear mount, if you want it or have any other questions, PM me. The twin turbo engine/mid mount was by far the most powerful setup (two garrett stage 5 turbine, 50 trim compressor t3/t4s), 1 of these is almost as large as a single garrett 60mm and the twin setup spooled nearly instantly). An engine mount single would be nice as wll since you won't need a scavenge pump. Also, if you want to go single, 60mm is fine if you want to make less than 400whp at safe boost levels (unless you're running an EFR or turbo with newer compressor wheel designs). I think a 67-72mm is the best fit for high power on low boost for the LLT, if going garrett and buying a cheaper turbo, try for a larger Q-trim turbine wheel instead of a P-trim.

So did you say you did try a rear mount? Did you have oiling issues?

Never had any oil issues with muffler replacement rear mount single or twin with lines directly plumbed to one strong oil return pump and returned to oil fill cap. However, mid mount cat replacement twins may requires more work like using a sump tank or one pump per turbo, depending on the turbos used and how low or high they sit.

If i went rear mount i would be doing the sts design n probly replace a rear muffler. Do u have any advice for that to avoid issues on our platform? I would be using a turbowerx exa pump

So I was also looking into this, and I just want to know if it is even possible to get the LFX Engine to higher hp. I have a 2014 1lt convertible, and I am trying to build a setup that will make around 550 rwhp or 600. If it is even possible. If not what do you think the highest hp is that I can reach with a custom turbo setup, and my engine?

550-600 rwhp is possible, but a lot more involved than you think. I would read through the thread by JantzenOKC to see how much he did to get 600~ rwhp

Without building the block and transmission (weak point is the transmission) you are going to be around 500rwhp. I am currently pushing what a stock bottem end LFX can handle at 520rwhp.

Either build it or try to swap in a 6L80E or 6L90E. Im looking to get a low mileage 6L90E and swap it in; however, that means we will need to probably make a custom adapter plate and potentially a cradle.
