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.

Any updates?

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.

:yum:

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

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.

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?

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?

24 pages later... No numbers, no nothing ;-(

Take a guess why ??

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:

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.
