Product Description

*Currently made to order

*Cannot be shipped to California addresses

SDP Duramax 2011-2015  LML twins- up to 750RWHP

 

Instructions link- INSTRUCTIONS

*If you do not currently have an aftermarket drivers side IC pipe, you will need to purchase ours with the kit. The factory drivers side (hot side) silicone boots are weak and will blow apart with the extra pressure. If you select the drivers side pipe with our kit, it will be coated to match!

 

-Keeps the 2nd battery under the hood.

-Includes 3" Y-bridge

-Includes 1gal custom SDP coolant tank WITH low level sensor (raw, polished or powdercoated)

-Completely TIG welded, makes for very smooth joints and the insides of the tubing are flush. We strive to have the highest quality welds in the industry.

-Custom higher flowing mouthpiece that is also o-ringed to ensure there are no boost leaks where the mouthpiece mates with the factory turbo.

-We include a V-band clamp for turbo mouthpiece whereas other kit reuse the factory weak worm gear clamp.

- V-banded crossover pipe on the S400 outlet and stock turbo mouthpiece and the necessary silicone boot, not using one will cause boost leaks to occur over time with heating and cooling

- PCV reroute

- The kit uses our S475 turbo with the larger exhaust housing so it is unnecessary to wastegate the setup, spoolup is seemingly stock with this turbo in the kit.

- Radiused T6 exhaust flange with a unique mounting setup that makes installation a breeze.

-We use the correct designed flange off of the back side of the factory exhaust housing, they are CNC machined and are desinged to tightly slip inside the outlet of the exhaust housing and seal exhaust flow at the v-band connection.

-High quality stainless steel v-band clamps and t-bolt clamps are used at each connection.

-The hot side piping and exhaust housing are ceramic coated and heat wrapped.

-The cold side piping and compressor housing are powdercoated color of choice.

  2. Illusion Royal Twin Kit 5 Star Review

    Posted by on 1st Jul 2017

    I had waited for 3 weeks after tearing my truck down for parts to show up. Patience was wearing thin but once I got it all, the install is fairly easy and everything lined up good. Power has improved significantly. Looks great under the hood. If you're in Canada and order these parts, make sure to have them value it as low as possible or you'll end up paying extra $1000 on duty.

    From the amazing customer service from Scott and Felicia, to the amazing fitment of this kit, there is no doubt why these guys are the best in the business. The fitment of this kit is excellent! The pictures just don't do the justice this kit deserves. The new power is incredible. Scott and his team have my business from now on!

  5. Great Compound Set Up!! 5 Star Review

    Posted by on 21st Nov 2016

    This kit looks really good, just like all Scotts stuff. I went w the billet 480 over stock on a 2012 lml. I'm installing the kit myself and I'm about half way through, the install is fairly easy, just takes some time. The hardest part will be drilling the pan. Can't wait to get running and dialed in.

  7. Awesome twin kit! 5 Star Review

    Posted by on 30th Sep 2015

    I have to admit Scott and the guys at SDP built me a beautiful kit. All of the parts in the kit came with an impressive amount of detail and fit together great. I love the finished look under the hood and, the truck drives amazing! I would recommend this kit to anyone who is considering turbo upgrades.

    Posted by on 13th Sep 2015

    Installed this twin kit on my LML and all I can say is wow! This kit is top notch all the way around and the truck runs as good as it looks.... It's amazing the power gain while keeping the egt's low! Well worth every penny...
    Thanks Scott! Look forward to doing more business with you in the future!


  9. twin turbo kit for 2012 LML 5 Star Review

    Posted by on 18th Aug 2015

    I just recently received my turbo kit in the mail. The kit looked great! Awesome welds all the way around. Everything in the kit mounted up perfect. The kit came with a nice set of very detailed instructions. Best turbo kit and tech support by far!


  10. LML twin turbo kit 5 Star Review

    Posted by on 9th Feb 2015

    I installed the LML twin turbo kit on my 2012 duramax myself. Install was pretty straight forward, the kit came with all the parts I needed, everything fit perfect, and looks great under the hood. Scott was more than helpful with questions I had from before I purchased to the install, even emailed me back at 11pm when I had a question about the egr coolant lines. I've driven the truck with stock cp4/ trans safe tuning for a while waiting to get my tranny done, GM should have built it that way. I can't believe how quiet it is (except the turbo whistle), how smooth the power is, and how much drivability improved. I'm glad I went with twins over a big single. Looking forward to throwing some fuel at it with warm weather coming and the tranny ready to handle it.
