BTW, can you post footage of the sound with a light revving? Have you checked the oil content to see if there are any shavings?

I'd like to trap 125, so that means I want 520-550whp.

I'll post a video later tonight when I get home from work around 11pm. I gave a few videos made of the noise. I changed the oil Friday night after 1800 miles. The oil had 0 shavings in it

May be from the high boost (highest for the vhr ive seen) and the VVEL system is breaking down from it??

could a bad head gasket cause you to lose oil pressure in the heads?

I hope you find the problem

Lifters maybe? But the tech at Infiniti was saying something about VVEL and how it couldn't be the lifters. This stuff is beyond me. I'm not an expert at internals. I'll do some data logging this week and check oil pressure.

Related? Similar noise ?

This is what the Infiniti tech I went to was talking about. The link isn't opening on my phone, so I'll have to check it later. But from what the tech said, it's not the VVEL.

Hopefully its just a bad head gasket and you just need to replace with a thicker/Stronger gasket.

The tech may be thinking vvel since its what our car uses to operate the intake valves which is what I was sort of thinking.

my question is, if it is the actual mechanical vvel components did you just hit the boost limit for this car and how could these components be strengthened.

I would defiantly baby baby the car

guess we will find out soon enough...

kosstick · 10-10-2011, 12:36 PM

Anyone know how much it would cost to get stronger pistons and rods?

'10Anamoly · 10-10-2011, 12:44 PM

Not sure who sells them pre-made for our specs, but virtually any company will make you custom rods and pistons if you send them a stock one to copy. Custom forged pistons are probably $600 a set and custom rods can vary heavily depending on specs (H-Beam, I-Beam, A-Beam, manufacturer, material, rod bolts, etc) but are likely $600-$800 for a premo set.

Carrillo makes amazing connecting rods and Ross Racing and Wiseco make strong forged pistons. You should consider though that the engine needs to be rebalanced very precisely since the rotating mass is changing from factory and the redline is quite high.

Just the pistons and rods are listed at about 2k at GTMs website:

GTM Motorsports*::*ENGINE INTERNALS*::*Pistons*::*GTM VQ37VHR Arias Piston Set 370Z/G37

Its amazing what simple research can do.

Yeah 600 might work for four cylinders but our v6s run the price up.

Ron · 10-10-2011, 02:28 PM

^^ 600 what?

Edit: nvm I just realized you were referring to '10Anamoly post, not sure why you quoted me lol

'10Anamoly · 10-10-2011, 04:12 PM

Just because GTM is a grand for the rods doesnt mean everyone is. My buddy had Carrillo make a forged set of a-beam rods for a 3.8 v6 (meaning 6 rods...) turbo firebird and paid $750 total. His pistons were $680 or so from Ross Racing with thermal coating on the tops.

You can pay as much as you want, but its does not mean you cant get quality for less money. You could easily spend $2000 on rods if you wanted to, or you can spend $750 and get a good set too. Quoting common vendor websites or pretending that only GTM's on the shelf options are available is a bit naive, but to each his own.

Ron · 10-10-2011, 04:17 PM

why are you getting all worked up at me? kosstick asked how much for rods and pistons and I gave him a website with prices for him to get an idea...THAT IS ALL.. Jeeeesus!

'10Anamoly · 10-10-2011, 04:19 PM

Not worked up, just correcting your suggestion that a V6 necessitates spending more than what I quoted, although you certainly can as you showed.

Ron · 10-10-2011, 04:21 PM

It wasn't meeee it was Equinox hahaha ... take a look, I never said you need to spend X amount, I just provided links

VQStryker · 10-10-2011, 05:05 PM

Take it to pm's, lets keep his thread clean and on topic.

Side note RON did only provide links but RON please don't take what he said to heart, he may not have ment it in such a way.

lets keep his thread clean get on topic guys
