Did you get a reply from them in the past 2 weeks? A few email sent but no reply from them.

And the anticipation continues......:stirthepot:

Navyboy916 11-06-2012 10:38 PM

Your telling me about the anticipation. I am currently gathering all the extra parts I need to get before the engine is put back together and in the car. I just ordered the urethane motor mounts from z1 motorsports to flex with the flexing of the motor when the throttle is quickly depressed. I have a lot of extra goodies going on the car when the motor is put back together.

u know you can street tune the same way u can dyno tune right?

SS_Firehawk 11-08-2012 11:44 AM

Is there a drag strip in Guam? Power can be estimated with trap speed.

:tup:The heads are currently being worked by the GTM they started working on the heads. I hope they are done soon cause the car being down really sucks right now. I know once I get them back it will be sweet. I also just bought the HD flex plate for the transmission. I have read some people changing the pistons and rods and actually working the bottom end. I want to keep the bottom end stock right now I have only 8500 miles on the car and the block is pretty stout. GTM even told me that the heads on our motors is where the power is and unleashing that power might not make power close to a turbo or supercharger kit but the reliability is still there and hearing that engine scream is music to my ears. Plus, I still smash on FORDS all day.:happydance:

I am sending the heads off today.

Navyboy, was it recommended to swap the valve train when doing this mod. Does JUN recommend it as well?

Dear Jermaine

These camshafts are designed for the Nissan stock valvesprings.

Navyboy916 11-14-2012 01:56 PM

When I talked to JUN they said the stock valve train could be used but they couldn't promise that they would last due to the high duration of the cams. They are currently making the new valve train set to go along with these cams. They said it goes hand in hand when swapping the cams out you should swap out the valve train. That was from JUN. I am spending the extra money and doing this right cause if you break something internal the consequences could be worse then if you just swapped the parts out.

red6spd 11-14-2012 02:12 PM

Much smarter doing it the way your doing, there is no such thing as cheap and reliable. Hopefully this cab be a much cheaper alternative to a TT or SC setup and make some decent power... Fingers crossed.

Navyboy916 11-14-2012 02:14 PM

Everyone knows the saying "You pay to play"

Navyboy916 11-14-2012 02:37 PM

I have read a lot of these post and notice that people have their idea of what is going to make power with these motors. I told myself just stick with the bolt ons and then work on the heads cause no matter how technologically advanced these motors become the basics of engine building still has to be considered so with any motor the true power lies in the heads. This is for everyone stick to the basics and remember the JUN cams are exhaust cams only.

SS_Firehawk 11-14-2012 03:22 PM

Up until recently, we only had half the equation to work with regarding the heads. With VVEL tuning in it's infancy, and these cams, this is truly a ground breaking time for the VHR's. Getting your heads done @ GTM is like icing on the cake. I won't doubt that within a year, UPrev will be including an upcharge for VVEL tuning on top of their normal etuning services.

" HD flex plate for the 7 AT " what is that

Z

Navyboy916 11-14-2012 07:32 PM

It's a heavy duty plate that is attached to the engine that connects the crank to the transmission. Like the flywheel for a manual

As of right now I am not planning on swapping out the gears. I might later when i get back to the states. Here is a pic of my new motor mounts from Z1 Motorsports.:happydance: These should help with the flexing of the motor they are really stout and well made.:tup:

You're probably going to get a lot more vibration in the cabin.

Navyboy916 11-14-2012 11:55 PM

Z1 tested these out and these being urethane had no vibration at all.

Z eliminator 11-15-2012 06:54 AM

Where did you get the HD flex plate from?
I had mine heat treated at GTM.
It on the car now with the stage 4 GTM tranney.
Still have to put the flash in it.
With the stock fuel curve in the car it pulls way harder than my stock 7 AT.

I have just received the full cylinder head gasket kit from nissan today and a new thermostat. I am hoping the heads will be done done next week from GTM. Here is a pic of what the Z's and G's rep here on Guam. They are located on the back windshield. Not a huge sticker fan but its going to look good and with not many Z's and G's here we will standout. It sure is depressing when your car is down for so long and the heads are halfway around the world. Hope GTM can show what these JUN cams and upgraded valve train will do when the heads are flowing so much better.

Sub'd. Great information so far. It's awesome to follow someone doing this.

jvg 12-06-2012 09:31 PM

Any updates?

Navyboy916 12-08-2012 05:25 AM

I have just received an email from GTM and the valves are taking the longest to make but they should be done either today or Monday and mike said the heads will be assembled and shipped by next week.

SS_Firehawk 12-08-2012 06:09 AM

:yum:

Get Get Get Gettin some heads, I was getting some heads

Navyboy916 12-26-2012 05:39 AM

Here is a startup of a built motor with the jun cams so u can listen to the idle. This was done in Germany they are in the process of getting whp numbers check it out!! This is not my car it just gives u an idea of what to look for if ur thinking about getting the cams. My heads are getting more work done then this car has. Props to GTM

Oh snap. Can't wait for results. Much props.

JC671 12-26-2012 07:09 PM

Sick....

This motor has a completely built bottom end though to include pistons rods etc. your build is just a complete head build correct?

What's the status on the build? It's been a month or so since you last posted and said the head is two weeks away.


When do you think all this is gonna be done?

Navyboy916 12-26-2012 08:27 PM

Gtm is really backed logged with work but Sam this morning said they will be finished in production by the end of the week so they will be shipping everything by the end of the week. I just bought the upgraded torque converter and hd flex plate. They said the valves took forever to make and they didn't think it was going to take this long but the wait is going to be worth it. U get the headers on? How r they?

I can only hazard a guess that Jun's numbers on their page are falsified, lol

And by the time the member from Guam gets his engine back, his numbers won't be worth a damn since his engine is getting an upgrade too

Because the OP went totally different route and went with Stage 2 SC and Stage 4 AT transmission. he is much happier now.. And take a guess.. he is looking to upgrade to stage 3 SC soon..:tiphat:

The Dimer 01-10-2013 09:55 AM

I still don't understand why so many people are all over these guys' backs. It's not like they're a company trying to sell you a product. They don't have to prove anything, they don't owe anyone anything. They're just a couple guys who decided to mod their cars and wanted to share their plans with the community.

Zuperman decided that they were not going to be worth the cost and decided to go another route, which is going to make his car leaps and bounds more enjoyable than just the cams would have.

Navyboy is taking the time to do things right. If you're doing cams, you should do a valve train upgrade, and if you paying to do all that you might as well go all out and get the head work done too. Even when that's done, he's stated several times that he does not have a dyno in Guam, so there still won't be dyno numbers apart from the ones Jun has posted on their website.

If you're not happy with what these guys are doing, then pony up the dough and get the answers yourself. I would, unfortunately I don't have that kind of disposable income at this point in my life, but I'm not going to come here and talk smack about the guys that are spending their money to try something no one else seems to have the cash/balls to do themselves.
