Variable silencing system I think it stands for.

It's a system to restrict the amount of air through the exhaust to quieten the car for silent mode. Might want to check if the valve is actually stuck or not as due to being in the exhaust they tend to get stuck in one position a lot.

Since my exhaust is still looked as something stock (I'm not sure about this actually), I'm going to test it soon (I've done it before but I didn't realize somethin' different).. By the way, is it a standard feature for this type of skyline? Thanks! :)

I think you're right, NJR 34GTT.. So it should give a significant change to the sound?? :( One member of skylineowners.com in UK also said that it is common for this optional system to be got stuck.. I will investigate this as soon as possible.. :)

m-p,

I have a 98 R34 GT-T semi-auto too & mine that switch!

If you switch from Silent to Sports mode, there is a noticeable difference. The exhaust note adopts a growl to it - not as loud though as a cannon type exhaust you see on many Skylines & Rex's.

You can tell the difference just parking & switching between the two, but more so when you "load the car up" driving up a hill, then swtch to sports mode.

My girl gets scared when I boot it up a hill (she's not really a car person, unfortunately!), but relaxes a bit when you switch it to silent.

If you check the exhaust just under the rear bumper, you will most likely see two pipes of different diameters feeding the exhaust itself. There must be a valve that the switches controls to toggle between the two.

Mine is a Nismo exhaust (brand stamped on the underside of the exhaust), so I'm thinking it may well have been a factory option.

Wow.. Great, Mean_R34! Seems that it really works in your skyline, so I think I must check my system and have a test soon.. :P I can't perform the check right now because it's already late nite, and seems that it's so dark outside (everybody knows that.. :P ).. Thanks! :(

      Hypergear Turbochargers and High flow Services Development thread

      Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)

      I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.

      Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.

      Wow the colour matched hard top completely transforms the car. Are there any nice front lip options for the car or is that off the table?

      Generally yes but for some reason I've been ruthless this time around!  I might even need to do another tip run after the way I've finally been able to hit the delete button on shit I've stepped over, stepped around and tripped over for the past 10 years!
