Single turbo - Going to GPI for drop-ins + ??
5 Attachment(s)
Only post a few times, but figured ide pipe up for advice prior to dropping the car off next month to GPI. 2016 SS with custom single turbo and baby 3" DP (I'm aware it'll be a restriction)
Long story short, had a very bad experience with a local shop who I dropped car off to only do hpfp, lt4 injectors, and base E85 tune. Car now needs refreshed with only 4k miles due to overboosting after they botched the WG. So, quick breakdown of what I ordered: - Aux low side (already have full lt4 low/high plus JMS) - SS2 turbo cam plus CHE and all DOD items - Ported stock heads with valve upgrades to Manley - Head studs - Mains upgraded - Circle D 32-3400 258mm stall - Drop in rods/piston combo (lower CR) - Snow stage 2.5 - AEM EBC That's the just of the main parts. What am I missing? Anything else I should do while it's all out? Debating options on DP, how it's routed doesn't leave ANY room for larger downpipe after bend, but might be able to get 4" to the first 90* and then drop to 3". No real goal, primary objective is to do what's necessary to hold power around 800whp. If fuel can't keep up without being reliant on meth, I'll be fine around 700whp until more options are on market for high side. MERRY XMAS YALL |

The wg is mounted to the cross over. When it open it reduces the volume of exhaust gas to the turbo. It seems like a less than ideal location but I have had kits with it in this location and it worked fine there. |

Kit was made by Triangle Speed before I purchased the car. WG picture doesn't show exactly how it's tied in, but I agree with what Parish said. They actually had the WG in 3 locations when building the kit, this one controlled the boost best. Dumping to atmosphere for now, not worried about noise at WOT. |
thats a great looking kit. If you are looking to burn money, add a electric cutout to the list and put it in the DP right under the starter. You have a great list of parts already. What turbo is that? The 3inch dp will still allow you to make great power.

I am currently doing my homework to build a gen6 single turbo so thanks for the thread.
What manifolds? What AR/trim turbo? Did you do a baro break out on this build? I'm curious about the tuning. Sorry for all the questions lol. |

The limiting factor on this set up will be the turbo itself. |

Stock passenger manifold crossovers to fabbed drivers manifold. Yes it has baro and IAT breakout. Precision 7675 CEA T4 stainless .96 is current turbo. Haven't decided if I want to swap to something different yet, open to suggestions. |
Thats a nice sized turbo for good power and instant spool. Where are you getting your oil feed from? and where are you returning it?

I had that exact turbo on a 383 LS motor and it maxed out in the mid 700s if I remember correctly. Swapped over to a Borg S480 with a 1.25 housing and was able to make over 1000 with it on a 408, 383 started knocking right after the swap.

King is accurate. Turbo setup was built by shop with intent to market for bolt on kit, not full tilt build. I feel the turbo was sized accurately for the intention at the time.
Open to turbo suggestions, as I could keep this for my GN project that will happen next year. Car goes to GPI on the 22nd, so I'm trying to have everything lined up. |
