Dirtgarage these sort of comments are pointless and don't help your cause. If winning superlap was as easy as buying a Vipec then they certainly are pretty special. You know as well as anybody that th

looking good mate. the HKS manifolds are good. there is definitely some merit in bridging the mani's (at least on paper). and the apexi turbos are great too. I have only been in 1 GTR with them and not driven it, but have tried them on a few other cars SR20s etc. and they are definitely good. :P

I had an Apexi turbo (AX53B70 P25) on my RB25, it was great made good power (250rwkw at 18psi) and my tuner remarked that it was one of the most responsive turbos he had tuned. However as i found out to my detriment they do not like to be oversped being ceramic turbines they will crack, get unbalanced ang break the shaft, they are no where as bad as stock turbos and if you keep the boost under 20psi you will be laughing!

no, definitely not ceramic. i have seen configurations which include these turbos running fairly high boost. ie 1.8bar plus. if they were ceramic, i doubt they would hold together under that sort of pressure.

The turbos are definatley not ceramic wheeled. The Apexi range of turbos are a very good turbo and I am confident that they will make good power. These turbos will have slightly more lag on a 2.6lt than a pair of 25/30's or -5 garrets due to their slightly larger size but will make really good top end with good mid range response.

Atomicbomberman and myself have both been extremely busy with work and some other commitments so there has not been a great deal of progress but there should be some updates on the build coming soon.

updates updates updates.... damn it!

Ok, sorry ive been a bit quiet. Photos are all over the place, and i need to get them into some sort of order. I've got so many photos. sorry if the picture sequences get a little long winded. I'll try to pick up where i left off.

Here is a front view of the turbos mounted on the manifolds. For those with a keen eye, you will notice that there is a 5mm stainless spacer between the manifolds and the turbo exhaust housings. This was because there was a clearance issue where the turbo housing slightly interfering with the manifold. I think this was due to a mixture of brands, HKS manifolds, Apexi Turbos and Tomei dump pipes. This is another example of where Daz doesnt cut any corners. Any other builder would have probably jammed in a few more gaskets to get the clearance and be done with it. Instead he had the spacers custom made using a laser cutter for a neat and professional finish.

Water and oil lines were fairly tight together

All hooked up.........

BUT.................................THE LINES LOOKED SO MESSY! The lines in the Apexi kit were way too long.

Daz disconnected the lines and resized them all. Mr RUZIC (Ruzic Engineering) and Dr Tran (9krpm) were both there for Quality Control.

Daz seems to have a tool for EVERYTHING!

MUCH MUCH BETTER!

Disconnected once again to put the heat sleeves on.

Getting closer to the DESIRED look! :) I really hope the Apexi's give the response i'm looking for.

Good to know the Z-TUNE uses IHI based turbines too! If my car runs half as good as the M-speed or Z-Tune i think i'll be a happy man!

Daz used multi layer hi temp silicone hoses for the oil return on the turbos. Bought the right bends and cut them to size. Very neat and tidy. I cant believe how expensive these were!

Rear turbo. The gooey stuff between the the return line and the block is not oil. Its a sealant for the gasket.

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.

      To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all
