GReddy Twin Turbo 2011 Nismo installed and tuned @ Motion Lab

Motion Lab

Hello Z owners. We recently signed up as a supporter of these forums in light of some of the cool 370z projects we have been working on. This post is to highlight one of our most recent projects, a twin turbo 2011 nismo edition 370z for a local customer here in the Charlotte area. We decided to install the kit with the motor still in the car. Progress was happening quickly but I have some O.K. photos to share. We utilized the GReddy twin turbo kit, DeatschWerks 850cc injectors and 320LPH fuel pump, and the UpRev Osiris tuning suite.

We met Richard one day as he stopped by the shop. He had just picked up a Nismo 370z within the past few months and did the typical intake and exhaust mods but just wasnt happy with the gains. We discussed the different options available on the market. We started looking at the Stillen supercharger kits as we had just tuned a 2010 370z with their stage2 kit that hit 420WHP on a Mustang dyno. He liked the powerband, but wanted to have more potential in the future. We ended up deciding on utilizing the GReddy twin turbo kit. This kit was very complete (outside of a few small components left out during packaging) but did not include any fuel system modifications or tuning solution. We have been direct with DeatschWerks since the beginning of the year, and have had the UpRev software for over a year for some of the 350z projects we had been a part of. We turned to them to round out the necessary modifications to make this transformation complete

Pic of some of the GReddy components upon arrival:
Once the kit came in we had Richard drop the car off. We had our technician Nate inspect the kit and begin tear down. Since we were pulling the transmission out, we decided to give it a shot with the motor in the car. It was a tight fit but Nate worked diligently to get everything to fit as advertised.


We started by pulling the transmission to fit up the new clutch kit, and make our lives a little easier when it came to fitting the turbos. Then we started fitting the manifolds and installing the necessary heat shielding. Once we had everything mounted I went out and snapped a quick picture before Nate moved on.


This kit came with a new cast oil pan. Great looking piece and made installation of oil feed lines a snap. Increased the capacity by about a quart. This is where we ran into the first missing part, the oil pickup tube spacer. Because the pan actually sat lower, you needed to utilize a small machined spacer to keep the pick-up tube at the bottom of the sump. GReddy is all the way in California, and for the sake of time we went ahead and had our local machinist make us what we need. Its good to be in this area, as we are surrounded by talented individuals!


After that, we started to tackle the seemingly endless trail of aluminum piping. Intakes, intercooler, and intercooler piping was the last step after the fuel injectors and fuel pump. Took us roughly a day to finish up this part of the project as Nate is also somewhat of a perfectionist. Not a bad attribute to have in a technician . This is also when we found the other two missing pieces out of the kit. Two reducer couplers. We needed an answer in a hurry, tough to match GReddy blue, so we went with a nice 4ply reinforced silicon reducer from Mishimoto. Unfortunately Samco was out of stock, and GReddy USA tends to move at a snails pace. Please excuse the color differences.

After that, unfortunately I dont have any pics, we fitted a Mishimoto low temp thermostat and Cosworth 1.3bar cap. Just want to make sure the cooling system was up to the task. After that, this build was just about wrapped up. We swapped in a set of DILKAR8A8 (GT-R plugs) for a more appropriate gap and then we started tuning.


After dialing in the injectors, MAF, and smoothing the ignition timing on the street it was time to strap it down and see what she was gonna do. Dyno runs were done in 4th gear on a Mustang 2WD dyno. Kit was only running wastegate pressure out the box. Final power numbers were 440whp and 339wtq at just 5.5PSI.


Here at Motion Lab we always like to take a step back and see what is really working. When Todd was at the dyno he overlayed the 2010 370z that we tuned with a Stillen stage2 kit versus the twin turbo equipped 2011 nismo that we just finished building. The good news is that both are exceptional quality kits that deliver the power advertised.


After completion we tried our hand a little video editing. Glory did a great job editing a quick video to showcase the car a little and show a few pulls on the dyno. Hope you guys enjoyed this little expose on the Nismo Z we transformed. Please check out the YouTube video below!

Thanks for taking the time to do this nice write-up with pics/vids. I'm moving to SC and have been doing some research on the shops in the area. I might be paying y'all a visit later this year

Thanks for taking the time to read through it. We have since added an AEM TRU-Boost boost controller mounted in the center console, and turned the boost up to 8psi. We picked up another 40whp with the extra boost. Unfortunately the ACT clutch has began to slip in 5th and 6th gear when hes having some fun on the highway. We will most likely go with one of the OSGiken twin disc clutch kits.

Let me know if you need any more info, we are happy to help!

Thanks,

just curious but shouldnt the clutch and flywheel be broken in properly before getting the tune dialed in? doesnt the car need to be driven pretty aggressively for tuning purposes?

nice build btw!

I was under them impression that as long as your not shifting hard, a new clutch should be fine. You should be able to hit on it as long as its properly engaged in gear.

ahhhh thx

No a 500mi break-in period was observed with the fresh ACT clutch. If it was a puck style clutch with ceramic/metallic pads you do not have any break-in to worry about. If you have a organic disc, you must break the clutch in to have a good lifespan as well as hold the advertised power. This clutch kit when ordered had a rating of 435hp on the website. They seemed to have downgraded it since we originally purchased to 385hp. The OS Giken clutch should be able to handle about 700hp so that will be the next step to ensure we aren't having to do this very often, haha. We want to avoid a single disc puck style clutch to ensure best drive-ability as this is an almost exclusively street driven vehicle. Using a twin disc clutch helps hold more power while keeping a more OEM like engagement.

Of course its hard to rate a clutch in HP, as that's just a measurement of work over time. The torque is what makes it slip. Just like its hard to put a HP rating on a set of rods because torque is what will ultimately bend or break it.

My car is actually there as I speak, we are upgrading my stillen kit. You cant go wrong with these guys...!

FireDan50

How are you upgrading your Stillen SC? Impeller, pulley ?

Motion Lab

Thanks for the shout-out man! Got your injectors in this afternoon, gonna give Vortech a ring and tell you what I found and give an ETA on the tuning

Vortech is doing a impeller upgrade. The 928 motorsport impeller does not work with this particular V3 blower. Luckily they do have an in-house upgrade that should increase boost by a few psi which after tuning should provide another nice little jump in power.
