hi guys... i rarely post things. I am from the g35 world originally, but I have had the 2014 370z since the 2014 of April... I have done a lot of research, along with modifying my Z according to my past experiences, and my z is going beyond all I have ever imagined. My big question is for the first gen JWT exhaust cams.
I am NA, full bolt ons from motordyne, stillen gen 3's, and in the process of the JWT exhaust cams. The hiccup i have is the valve spring retainer. apparently there are different types of valve springs for different years on up for the OEM design. the JWT springs are "straight" and my OEM springs are honeycomb. What do I need to do to get this issue sorted out? the JWT spring is wider because it is straight vs the honeycomb with has a widest with of the JWT but tapers to a smaller diameter. I ordered from Z1, and I live in California ( i know JWT is here), but I work odd night hours, issue happened over the weekend, and all businesses are closed now. so I was just seeing if anyone had a solution for the this until I get an answer back from Z1, or I am able to contact JWT ... Visuals attached. Its my instagram RXNIGHTFURY, and the picture is three images to scroll right for comparisons. Thank you in advance guys. https://www.instagram.com/p/BXeIyuEg...by=rxnightfury |
I'd call Daelen at MA motorsports first thing in the morning. He has tons of experience with VQs and cams and has been nothing but helpful. I think he even wrote something about it on here I can't remember. It might be in this thread.

Okay, thanks. I'll try to search through the thread again. I just skimmed it. Otherwise i'll try to give them a call

Since you said you work weird hours you can email me also Daelen at MA-Motorsports.com You have the "late model" springs in that head with the new shorter valves, you will need the retainers from the old style springs, and if I remember correctly the lower spring spacers to get it all into the correct installed height. Ill double check my info as its been a little bit since we did one on the new style heads. Also keep in mind, double check the lash and if it is out of spec, you will need the new style buckets also. The older style will not work. -Daelen |
The time has come! What you have all been waiting for is finally here. The Jim Wolf Technologies C2 Camshafts for the VQ37VHR are finally available! I will be opening up a Group buy here in the next day or so, will post the link when I do. Jarred was nice enough to ship his car up here last week for the final phase of testing, as we wanted a car that had the full "breather" modifications installed to really see how well they performed. Previous test vehicles used for fitment and long term testing showed that a stock platform left a lot to be desired. http://www.ma-motorsports.com/wp-con...beck370Z-3.jpg Jarred's car had the following modifications when it arrived: Z1 Intakes Factory Intake manifold Factory throttle bodies Long Tube headers (Ex IMSA team, we saw very similar gains with the Fast Intentions Long Tubes) Custom Y Pipe (Motordyne Style with 2 Cats built in) Amuse R1000 Catback Exhaust ECUTek Tune (We did not tune previously, was done by another well known/trusted shop) We put the car on our dyno to get the baseline reading before any changes where made: http://www.ma-motorsports.com/wp-con...eck370Z-11.jpg The car then went on the lift and the engine was removed to give room for the install. As we replaced the cams, the following parts were also changed: Factory Water pump New Oil Galley gaskets Suckerpunch Oil Pump JWT C2 Cams, and springs. We added the oil pump so we would be able to safely rev the engine a bit higher and make use of the cams. We see lots of talk about the limit being raised on these engines, one weak point that is easily replaced during this job is the pump. The other limiting factors are within the VVEL system, and have been found to become a problem around 8000RPM in repeated cases. It is something we will be looking into, but in most cases you will not want/need to rev them much harder as to help with longevity of the engines life. Hard Fuel cuts, and high limiters will be detrimental to the life of your VQ37VHR, so keep that in mind. After the install the car went onto the dyno to be re-calibrated on the ECUtek software for the cams. http://www.ma-motorsports.com/wp-con...beck370Z-6.jpg All in all we are very impressed with the power made over the stock configuration. With a baseline power of 268whp and 219ftlb, and a final number of 305whp and 241ftlb the gains were very impressive. http://www.ma-motorsports.com/wp-con...2205604352.jpg For reference, we use a Dyno Dynamics dyno, controlled by Mainline Dyno electronics. By far one of the lowest reading dynos out there. Nicknamed the "Heartbraker" for a reason. **Note, on this dyno graph we had a pickup issue, redline is actually 7900rpm not 7500 as noted on the sheet** The idle is nearly stock with a slight lope, and drivability is on par with the stock cam shafts. All in all, a great package for anyone looking to stay naturally aspirated and keep the car very drivable. After completion Jarred drove the car home nearly 14 hours. I will let him chime in with how it felt to him. We look forward to refining the package and finding other power restrictions in the system. For fun here is Jarred's dyno graph, laid over my 2011 370Z when bone stock. http://www.ma-motorsports.com/wp-con...2205576963.jpg |
Wow very impressive through the whole power band. if i am reading this right 37whp and 22wtq after tuning?
|
Another unnecessary buy for me again, damn you

Wow, that dyno is a heartbreaker. Good before and after numbers though.
