    Ask Us Anything!

    Hey fellow members!We recently released a tech article about what a turbo manifold does and took part in a podcast with HP Academy that briefly went over some of it, too.We had been thinking about doing an Ask Us Anything (in relation to our work) and right now seems like the perfect time...

    What does a turbo manifold actually do?

    I was recently asked this question and completely botched the answer- making it seem like they do nothing. So now is a good time to share what we’ve learned so far.We have both a short answer and a long answer to this question. There are more factors and details involved but this aspect...

    V-band Turbo Flange Compatibility

    Not all v-band turbos share the same v-band flange. For most common brands/options it comes down to the centering ring size- the male lip on the manifold outlet and matching female groove on the turbine housing inlet. Each brand has a different size groove, so some brand turbos will "fit" on...

    Turbo Manifold (DSM Stock Replacement) Video with Design Aspects/Challenges

    Showing some design aspects/challenges with our fabricated/tubular DSM stock replacement manifold and why they are important for power per psi for all turbo manifolds and generating more airflow with less boost by having less residual exhaust gas remaining in the cylinder. Hoping to have more...

    Morrison Fabrications 2021 DSM Shootout Tech Seminar

    We did a tech seminar at the 2021 DSM Shootout.This briefly goes into what a turbo exhaust manifold does and goes over the testing we’ve done.We are currently developing (what will seem like) a novel and several videos delving into it much, much deeper; once complete, we will share it here...

    5/8" (-10) Oil Drain Kits- Garrett, EFR, Xona, PTE

    We've added DSM and Evo 5/8" turbo oil drain kits to the line-up for applications that the 3/4" kits didn't quite fit, allowing a drain kit for just about every turbo. The 3/4" kit is excellent for Borg Warner S300/400 and Holsets that require a large diameter drain to handle the oil...

    MHI/FP Turbo Oil Drain Kit

    Full flow 5/8" drain kit for 14b/16g/FP bolt-on turbos where the factory drain doesn't quite work or if you would rather slide a hose off during turbo removal instead of dealing with gaskets. Each fitting is slightly angled toward each other for an easier bend with the high temp hose and the oil...

    Large vs Small Runner Dyno test!

    Large Runner vs. Small runnerWe’ve always felt strongly about taking advantage of runner/primary sizing and matching it to the setup, which is nothing new for manifold/header building, but somewhat uncommon for most DSM and Evo turbo manifolds. Historically, “large” runner options have been...

    DSM Stock Replacement Manifold Back-to-Back Dyno Testing

    Just a few months before this test, we would have unquestionably suggested a cast option to anyone looking for a bolt-on, stock DSM flange manifold. It has long been the consensus that “cast is king” in the DSM bolt-on turbo world. However, people kept asking and new bolt-on turbo options were...

    New Product Testing: DSM Stock Replacement

    DSM Stock Replacement.Historically it's something we haven't offered due to the compromised bends and entry angles when fitting a fabricated manifold between the tightly placed factory flanges. It's not something we gave up on and are happy to prove ourselves wrong, even if it requires getting...

    What Sets Us Apart

    Hello! We wanted to highlight some of the things that we find important, and also happen to be some things that set us apart:▪️It starts with an oval port exhaust flange. We feel very strongly about using formed runners instead of the entire oval to round transition being done within a 1/2"...

    Large Diameter 3/4" (-12) Oil Drain Kit- Holset, PTE, Borg Warner, etc

    Since our first (non bolt-on) turbo swap, we've been salvaging OEM Holset drain lines to make a true 3/4" drain line. And while AN fittings and lines work, we’ve always preferred a simple clamped hose with fittings that are much closer to an actual 3/4″ ID than a comparable AN fitting. Not being...

    321 Stainless is now our standard manifold material!

    We've been eyeing up 321 for many years and were really excited to find a solid supplier to make the switch. While 304L works very well (and has been/still is the standard manifold material used across the board), 321 is a stabilized grade of stainless that has much more ideal high temperature...

Zak plans on making some changes this season and we can’t wait to see what he does next. Easily...

    DSM Tensioner to Saturn Alternator Adapter

    We aren’t necessarily for or against switching to a Saturn alternator as there are pros and cons to each that have been covered throughout the years.

    Auto Shift Lever and Bracket

    The factory shift lever is 3″ tall and takes up space that is normally used for upper intercooler piping. This lower profile shift lever is about 1″ tall, and has been designed with its own shift cable bracket to maintain the factory motion ratios. This gives more room for intercooler piping...

    1g Radiator Mount Modification

    Every 1g we get our hands on, we move the bottom radiator mounts forward ~3″ so it’s straight up and down. This creates an enormous space savings for puller fans and lower intercooler piping. For a bottom mount, you can often use stock fans, and a top mount can run a larger downpipe under the...

    1g DSM Auto Shift Lever and Bracket

    When we acquired an automatic, one glaring difference was the shift lever off the transmission is (almost) as awkwardly tall as the shifter inside the car; and is right where you want to run the intercooler piping. This lower profile shift lever is ~1″ vs. the factory 3" tall, and has been...

    Oval Port Exhaust Flange vs. Transition Exhaust Flange

We went into our search knowing that each runner, from the exhaust...
