Okay so I know Trent's running a 7675 and have spoken to him already but I'm wondering about the response of these turbos that only people have experienced.

I have the 7675 in my site but the t51r and gt4202 and closely sized.

Any info would help.

My Gtr is running a rb26/30 and currently have a 72mm turbo but lookin to up the anti possibly.

People are probly going to ask my power goal so I'm going to say 700-800hpwhp and car will be run on e85.

I know my turbo may be capable of the power but I don't want to run 40psi to make it either.

Car is street registered but wouldn't mind taken it to the strip either and being fairly competitive.

Really just scared of too much lag with a rev limit of say 8000rpm and don't want to "have to" run nitrous but I will if I have to.

I actually just bought a clutch off a guy today that had a t51r SPL on a rb26.

He was hitting full boost (forgot to ask what boost)

At 5500 which is not bad at all.

Also Trent from mercury Motorsport runs a PT7675 on a rb26 making 35-40psi at about 6000rpm on which he explains is tired and low comp with 110psi across all cylinders.

I was just worried I may of needed to run nitrous if I had too much lag on my rb30 but it sounds like I would be okay with my extra .4Litres of displacement.

Any other experiences will be greatly appreciated

old tech. Don't get me wrong.I ran T88s,T51r kai etc.All Ment for strokers like yours or nos.Now I have a T78 but this is due to my power to weight ratios.

Problem is your revs. Can't rev up stick to a New tech Borg Warner 9180 check it out.Will spool super fast in your set up

      Skyline’s charcoal canister !

      By joshuaho96 · Posted

      https://sci-hub.se/https://doi.org/10.4271/2005-01-3825 Heat causes positive pressure in the tank, a slight vacuum in the tank is normally caused by evap purge during normal driving. If the tank is cooled it can also cause a vacuum that pulls air into the system. The linked paper is quite interesting to learn the state of the art for evap fuel control, modern systems the tank is 100% sealed and the tank is reinforced to handle higher than normal pressure/vacuum. It only opens the vent/charcoal canister when you press the button to open the refuel door or when the engine is running. After some reading of systems like the W220 S-Class there's a check valve on the tank vent, but the primary reason it's there is because otherwise the intake manifold would be pulling vacuum on the tank: https://w220.wiki/EVAP_system   There might be limited vacuum relief via the charcoal canister, but I don't know how sensitive the check valve is.

      Anyone know this frontpipe?

      By GTSBoy · Posted

      But there's the archetype for the name plate! Here's my view on that stupid TÜV ruleset. Buy a brand name aftermarket piece of equipment. In this case, the Mines front pipe we're talking about. Get it TÜV certified on the car. Damage the underside of it, say on a speed bump. Cut out the damaged section, replace with fresh metal. (For the sake of the argument only), continue doing that to the whole pipe until it is all gone, replaced with new metal. Is this grandfather's axe still the same front pipe? The design hasn't changed (much). The pipe walls are in the same places. The flanges are in the same places. It is functionally identical. How does this differ from a pipe that is ever so slightly different in fabrication (ie the number of welds in it, a few mm here and there in terms of where the pipes run, are joined, etc)? Anyone with 0.5% of a brain can see that there is absolutely no way that the performance (power, environmental aspects, noise, etc etc) of it can be any different than the genuine Mines pipe. Maybe even Mines made 2 versions of this design, with the same differences. How would anyone (say a TÜV inspector) ever be able to differentiate between them? And yet, they are so bloody anally retentive about this stuff. Mad. How upset would they be if you had the wrong spring washers on the flanges?
