Hey guys.

My car (S1 R33 Gts-t) is currently running the following.

ITS460 (460hp internally gated T04e)

Wolf3dv4

FMIC

Fuel Pump

Malpassi FPR

3inch zorst all the way

I've been advised to leave it at 16psi due to the injectors maxing out and have managed about 230rwkw from this setup with according to the tuner (P.I.T.S), plenty left in the turbo.

So I'm going to do my injectors shortly. 550cc Nismos or something similar. This will allow me to run 18-20psi boost which will mean I'll be getting the best out of my turbo rather than running it under it's efficiency level as is at the moment. The power curve climbs and climbs and then drops as soon at it hits the rev limiter.

Now as this is going to require a retune, I thought that I might as get get some aftermarket cams installed at the same time. I'd really want more power and torque through the midrange where it's lacking at the moment and the faster spool times as well as higher boost should keep me content.

From what I've read and searched here, the way to go is the Tomei Poncams as they directly replace the stock cams without further modifications. I've also read that on an RB25 the timing works best at 0 degress meaning I won't need to purchase adjustable cam gear.

After this, I'm going to stop mods completely.

Does this sound like a suitable idea? Will I benefit from having the cams installed considering my current setup?

Thanks for any advice or hints.

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      I made a little more progress last night and added some E85 safe fuel tank baffle foam in behind the stock cam cover baffle plate.  It still feels really wrong shoving foam inside the engine but apparently its fine based on it pretty much being the MINES/Hi-Octane RB26 cam baffle kit and the few posts here I have found of people doing it and the lack of posts saying the foam broke down and ruined the motor... Still plan to check it frequently though lol The last step for this round of oil control modifications I plan to make is to add some -12AN fittings to the cam covers and connect them to some (already existing luckily) -12AN fittings on the sump. Basically a sudo head drain/sump breather/pressure equaliser without having to remove the motor and do the one on the rear of the head. My plan is to add them to either the tops or the sides of the cam covers at the back. unless there is a compelling reason to have them at the front on the sides which i have seen a few times though they were all on RB26 cam covers from memory so that may be due to the stock breathers being on the back and the integral baffle being different ?

      Import insurance in 2025

      By CRSKmD · Posted

      from an old insurance company i was with (Budget Direct) I had someone roll back into me at the lights got them to pull over. Got a picture of thier licence with address, had a dash cam video and, thier phone number. But only had 3rd party on the shitbox i was driving. insurance did nothing, cops wouldn't do anything due to the value of the damage (under $3000) so i just had to suck it up and go to U Pull It.

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Small Update on the Exhaust Situation A 200-cell cat was a bit too expensive for now, so I had the exhaust shop fabricate a new exhaust from the cat to the rear and an exhaust tip. I went this route to avoid cutting into the original exhaust and keep it intact. It’s essentially straight-piped, and the sound is noticeably different. The exhaust tip came with a silencer, so if it gets too loud, I can easily install it to tone things down slightly. Right now, the car bangs and pops like crazy -- which I personally love. In the future, I might add a resonator or a 200-cell cat, as niZmO_Man suggested, but for now, I’m really happy with how it turned out.

      And that's a massive problem, because deadshits will deadshit and give you false details. At least in these days of mobile cameraphones, it is trivial to take photos of any ID they are carrying at the same time as the 300 photo extensive documentation of the state of the vehicles that I recommend even for minor incidents. And you get photos of the person's face, any visible tatoos, etc etc, while you're at it. Then you try to avoid mentioning that you're fully capable of making explosives of various power levels and will wreck their shit if you are forced to hunt them down.
