  1. Here's another ad the lights are in https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com.au%2Fulk%2Fitm%2F302587878885
  2. Fresh S15 Splitfires, never installed or used. Can ship anywhere in Aus. $360 GFB Mach 2 adjustable stock location BOV for S15. Only used for a few thousand kms, still very good condition. Can ship anywhere in Aus. $100 Mars S15 LED taillights, no globes included. Working when taken off car, pretty good condition. Just too pimp for me. $120, ceebs shipping unless someone twists my arm. Can meet up near Prahran, Knox City or Dandenong depending on time of day. Any questions just PM
  3. Anyone reckon something like this could be snuck into a Silvia engine bay to squeeze more street-friendly bottom end out of the SR or is it just another pipe dream? Guessing it would at least be more compact than a belt-driven option. https://www.borgwarner.com/en/news-media/press-releases/2017/04/28/borgwarner-s-ebooster-electrically-driven-compressor-celebrates-premiere?utm_source=Facebook&utm_medium=Post&utm_campaign=eBooster%20press%20release Comment from their facebook post: "The 48V eBooster cannot be used with just a 12V battery, however we do intend to develop and release (in the future) a specific 12V version for low-voltage applications. The eBooster couldn’t be a suitable turbocharger replacement in most instances since it makes a fairly low pressure ratio and runs out of flow capacity midway through the engine speed range. However, there may be some niche applications where these constraints are OK. Generally speaking, the eBooster and the turbocharger are intended to work together in tandem with the eBooster taking care of low speed operation and transients and the turbocharger taking over the primary duty once the engine has achieved the target boost pressure, including higher engine speeds. Hope that helps answer your question."
  4. S14 sr20det t28 laggy

    Can confirm wastegate leak will lead to a very bad time. Fixed my t28bb's kowabunga actuator preload by a couple mm and went from 16psi at 4500rpm to 16psi at 3500rpm plus way better transient response. Prior to finding that I checked for boost leaks, dead vtc, collapsed cat, knock sensor etc. If that crack has enlarged near your wastegate then there's a chance it could be replicating the same effect.
  5. Nissan consult bluetooth adaptor

    I found the BT adapter from Track Electronics works well with the NDSI app (Android). Haven't tested extensively but that app in particular responded well for me.
  6. WOW - What happened?

    Yesss stoked to see NS stay alive even though I've done pretty much nothing but lurk for the last 10 years. Some top reading on here. And agree with some of them earlier comments that the facebook groups just ask the same questions over and over when prob 90% of the answers have been here for years. N00bz needa get on it.
  7. Sr20 sumps

    Aeroflow is on special on fleabay at the moment $289 http://m.ebay.com.au/itm?itemId=262578138888 Haven't compared to tomei or moroso but guessing it's cheaper.
  8. Cheers for the advice. Yep, twin-scroll is my "gunna" upgrade 👌
  9. For now, whatever the t28bb can put out. In future, leaning towards hypergear atr28ss1.5 cbb (guessing max 250kW). So pretty much less power on pump98 than those results you got on that run-of-the-mill dump setup. So do you reckon on that setup you tuned it could have more gains before the peak curve with a larger diameter dump? I'm thinking in terms of streetability.
  10. Yep I'd definitely be wanting standard position - dammit, there goes that easy fix. I'm sure if I get this done the option is always there to butcher and use my jjr front pipe (or a donor 5-bolt dump) and step diameter up later like what was done with your example you posted and what I'm imagining wing's one to look like.
  11. Yeah figured it would be tricky given the shape of the stock dump flange. Perhaps with a t25 3" v-band adapter (like this http://www.ebay.com.au/itm/121655554934) it could be done, if there isn't some issue with using them? And these massive gains you mentioned, do you mean throttle response and mid-range? My s15 is a daily so I'm looking for anything that gives more response and mid-range - trying not to fall for the temptation of big peak numbers. Guessing with a larger dump a 3.5 or 4" cat would be a smart move too.
  12. Cheers for the feedback guys. Yep I've got a jjr 3" bellmouth dump (plus 3" all the way back) and it goes awesome considering how cheap and readily available it was - just wondered if anyone had done any similar back to back testing on different sized dumps with SRs. Was hoping maybe it was another way to improve transient response. Guess it's just not a big thing on SRs, and fair enough. Will have to look more into the in-bay cooler setup though.
  13. So I've been searching around for ages and haven't been able to find much info about dump pipes larger than 3 inches on a single turbo application (T2/stock mani on Sr in this case, for arguments' sake). My inspiration for this question is from a facebook post by a guy who does lots of fab for JZs (post is at: https://m.facebook.com/story.php?story_fbid=1683547575250381&id=1655171301421342 ) His results going from 3 to 4 to 6.5 inch show the boost delivery getting proportionally earlier in the rev range. There's heaps about split vs. bellmouth but I'm curious to know if anyone has ever seen any solid gains below the curve with an enlarged 4/5/whatever inch dump pipe on a single turbo application where say the dump ID expands after the flange where possible - similar to the dumps in the facebook post. I know that post is about twin-turbo and with a completely different style dump but his dyno results plague me with the question of "what if?"... I would gladly fork out money for such a simple exhaust mod that gives significantly more response without having to commit to a high-mounted twin-scroll setup. So, have I missed this info somewhere or does it just never come up because it is known to be completely useless?
