When do you think you will have these put in?

I am waiting for the dealership to give me a price to install I am going in today to check on it?

The car is going in next weds to get the cams installed. They are charging me 1500.00 for the labor and the Nissan manual calls for two full days of work. They have to make sure the exhaust lifters are not to loose or two tight due to the increase duration of the cams

definitely looking forward to this.

Navyboy916 09-18-2012 01:04 AM

I want to see dyno results! I would imagine tuning is mandatory with these. I'm on the ropes in buying these, don't want to bite the bullet till I see results :P

He does not have a dyno in his city so we wont see real results. all that we will see from this is that the install went ok. And if he FEELS any added power

Has the mfg not done testing of these on a VQ37VHR?

Edit: Google is my friend: http://www.junauto.co.jp/news/enews000163.html

Looks like their test has a lot of supporting mods though. Their own custom tune, different pistons, different rods, different injectors, etc...

I didn't like their graph because it doesn't specify if it was crank or whp. Not only that, 12.3:1 compression is definitely having an effect. And who does engine mods like that and does nothing with intakes, LTH/TP/HFC, exhaust, etc? I want to see a real dyno sheet, not some plotted points.

Navyboy916 09-19-2012 02:43 PM

I won't be able to give you dyno numbers sorry. I have been in contact with jun and actually they have created these cams to work in a stock motor. If any mod had to be done it should have been done in the head if the cam was to aggressive but it's made for the stock setup. The stock exhaust cams have a 264 duration and the jun cams are a 272 duration so I imagine some gain will be seen but it's not aggressive so don't expect massive gains.

edub370 09-25-2012 02:32 PM

cars going in tomorrow for these cams correct?

if these turn out to be great, we should get a group fund together to ship your car to a dyno lol

Navyboy916 09-25-2012 04:03 PM

The car is already there I took it in yesterday
