SOHO Motorsports Single Turbo Kit w/ Motordyne Engineering Plenum Spacer Re
SOHO Motorsports Single Turbo Kit w/ Motordyne Engineering Plenum Spacer Review
This past weekend we had the opportunity to conduct a few tests on a DynoJet dynamometer with the Motordyne Engineering 5/16” intake manifold plenum spacer along with our single turbo kit on our 2005 non-revup Nissan 350Z. Previous tests that had been done with the SOHO single turbo kit were with the stock exhaust manifolds and no intake manifold plenum spacer, thus providing 392 hp and 406 ft-lbs of torque at a boost level of 8.58 psi. Nissan Engineers have done a phenomenal job designing the VQ35DE engine but as most of us know the stock plenum was not designed to its full potential. The plenum that comes on this vehicle from the factory was not designed particularly to aid in airflow in a forced induction system let alone any performance additions, meaning that that space inside the plenum is restrictive and detrimental to making horsepower.
Motordyne Engineering has done an excellent job of research and development on theri own in regards to the airflow restriction and benefits that can be achieved inside the VQ's plenum. With the addition of the 5/16 inch plenum spacer adding volume, the initial pressure drop that is inside the plenum is reduced by a factor of 9, thus increasing the overall airflow inside the plenum. With increased airflow comes an increase in the horsepower capabality. In previous tuning sessions with customer cars on NA setups along with plenum spacers we have seen good increases in horsepower numbers as high as 10-15+ rwhp. When we decided to add the spacer to our 350Z with stock manifolds and our turbo kit we were expecting good results and the goal was to see how low of boost we could run to make the same near 400 numbers that are common on daily driven setups in an effort to strain the motor even less than the very minimal amount it already does. As you can see in Figure 1 below, the two graph lines represent the SOHO turbo kit with no plenum spacer at boost levels of 5.82 (red) psi and 8.58 psi (blue).
Figure 1.
As you can see in Figure 1, in order for a 10% increase in horsepower and torque there is a 32% increase in boost pressure that is required, thus more stress on the engine internals. After installing the Motordyne Engineering 5/16" plenum spacer and some quick tuning of the stock computer with the aid of UpRev Osiris, we saw a drastic increase in power and a drop in necessary boost pressure to achieve almost the same power levels at nearly half the boost. In Figure 2 below, these were the horsepower and torque values that we achieved with only the addition of the 5/16” plenum spacer, and in Figure 3 you can see the comparison of horsepower numbers against the dynamometer pull at a boost pressure of 8.58psi.
Figure 2.
Figure 3.
There was around a 9 rwhp and 14 ft-lbs difference between the two dynamometer pulls at SAE but there was a 45% difference in boost pressure to achieve these values. The plenum spacer definitely allowed the engine to breathe much easier and thus aided in creating incredible power at such a low boost pressure. This is a great discovery that we found on the dynamometer because it takes a substantial amount of stress off of the engine internals and allows the engine to operate at a more efficient level. With the addition of the plenum spacer we were able to achieve an incredible 26.21 horsepower per pound of boost and 32.26 ft-lbs of torque per pound of boost, making this turbo kit even more so one of the most efficient kits in the market in terms of power and torque per pound of boost.
As a comparison for sake of argument, a few months ago we had a 2003 Nissan non-revup 350Z with stock exhaust manifolds that we installed a Motordyne Engineering 5/16” plenum spacer along with a comparable single turbo kit. In Figure 4 below you can see the comparison between the SOHO Single Turbo Kit (blue) vs the Momentum Single Turbo kit (red) on identical vehicle setups on the same Dynojet dynamometer and at SAE.
Figure 4.
The comparable single turbo kit, which can be seen in Run 11 (red), made great safe power for a stock daily driven block but required around 42% more boost pressure to make the same power as the SOHO Turbo Kit (blue). Many people may say that the turbo that we have chosen is the main reason as to why we make these values, which is a large factor, but the overall design of the turbo kit along with the Garrett GTX35R turbo that we have chosen is why we make such great power at such low boost. In the next few weeks we will be testing the SOHO single turbo kit on a fully built race motor with headers and we anticipate great numbers at lower boost pressures as well.

Thanks! Im the guy who drives the car whenever we go to events and I must say it is damn impressive at the low boost, ive never seen or felt anything quite like it. This is by far the best kit on the market for these cars in my opinion.
hard to believe that you changed the VE of the motor that much by adding a plenum spacer.
You are basically saying that the plenum itself restricts more than then the intake valves.
I assume you left timing completely untouched and just fixed your AFR, which would be way off.
interesting data nonetheless. Next test should be doubling up the plenum spacers. The bigger the plenum volume, the less restriction effect it has on overall VE.

Soho everything looks great. I will make one suggestion. The WG mount is at a 90 degrees angle to the piping, This weld will crack over time and abuse on the track either change it to an angular mount or make sure to gusset it from the start.
This was sasha's first kit and after a lot of R&D he switched to a angular piping that was much shorter and less stress on the welds. When they break you lose significant spool time.
This is what I had to do to remedy the situation and since have had no issues.
I also don't see any flex piping in any of the kit. This will cause the gaskets in the downpipes from the headers to fail very quickly, also reducing spool.

We have track tested this kit for many many man miles in many applications on many different tracks on multiple setups with absolutely zero issues. Flex pipes always fall apart over time, as anyone with one on their exhausts im sure has seen it fray. As for weld cracks no way on earth, with our fabricator's welding process and quality stainless steel we wont ever have the issues you had on your kit. Also the angle the pipe comes off the merger it is the best possible angle for flow. I dont know how yours was welded or who did it, but our fabricator does amazing work that can withstand a nuke haha and absolutely zero issues after all of our track testing which I have abused to the fullest extent. All you have to do is look at the welds in the photos above to see that the quality speaks for itself. Our kit will not have the issues your kit has but I appreciate the input ... but...
In case anyone didnt know, our SOHO Turbo 350Z is a finalist in the Motor Trend Magazine / Nissan Project 370Z Challenge, along with two other cars... one of them being... you guessed it, the man who just posted above haha. I believe tomorrow they will announce the winner but I think I can speak for all of the top 3 finalists when we say we are just happy to have made it this far.
