Do you actually need a cannon? i'm not that well educated on the subject, but i thought cannons were for turbo cars, NA versions needed something more substantial to create sufficient backpressure to run well (or something like that). Anyone feel free to tell me otherwise, i'm in the market for a new exhaust system and don't want a loud, droning note.

if your exhaust is 2.5" factory its probly crush bent.

somthing that could make your guys lifes easyer with r33s you could buy the turbo guys factory exhuast as they are 2.5" mandrel bent from the factory. i have one on my car even tho its rb20e.. but that will be gone for a rb30de soon. lol.

yeah N/As need some back pressure as it helps the scavanging effect. a muffler like a flowmaster one would probly sound good. i will replace my stock rear muffler when i get the new motor put in as this one is a little rattly and doesn't make much sound. plus i don't get the typical skyline backfire :huh:

correct - stock exhaust was/is crush bent. will be interested to hear about your experience building the RB30DE

well so far i have most of everything that i will need to get it up and running. you can see the difference in rod lengths of rb30 and rb25. i just need to get the bottom end rebuilt and the head put on then i can finish the rest. it has a braded hose running from the head to just next to the oil filter. i will post some pics up when i have the basic block assembled.

i am only missing 3 major components, gearbox, clutch and computer plus ill need custom extractors.

it should be good when its all up and running. ill use a plug in GTS link once it is run in. hopfully completed and in car by end of january to mid febuary :D

Are you sure stock piping is 2.25"? I measured mine this morning for the new muffler and it came out to be a fraction less than 2" - the guy who imported it told me it was "dead stock". Why would anyone put on an exhaust which was smaller than stock (and mild steel to boot)?

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
