Best Intercooler Pipe Setup

hey hey.. ive done some searching but came up with nothing, cant win them all..

i was wondering what is the best intercooler setup on a rb25..

the intercooler setup were you crap extra piping and cross over the engine to the passanger side, or is it just as good mounting it to the stock pipes on the side..

i would think that the air would flow quicker this way?... I'm mainly confused as i seen this posted the other day..

(and bear in mind that 14psi @ the manifold is close to 17psi @ the compressor if you're still using the stock SMIC)

would this be the same issue if running a side flowing setup?.. or is it best to do a cross over the engine setup?

thanx , its held me back getting a cooler for a while..

Hey bro, when i first brought a skyline, i thought the same thing........ & i choose the re-turn flow option(CLEAN NEAT ENGINE BAY) (STEALTHY), i had a blitz one which was good and i heard people doing 300kws in them, i did 233 in mine and it runs good, no boost leaks nothing.. heres a picture if you wana see :blink:

Why you would run 14psi on the factory turbo/cooler is beyond my anyway.

There is no secret it does not flow well and poses a restriction. So if someone is running silly amounts through their own and having issues - those issues are theirs.

Running 10-11psi through the factory turbo is not just to stop it destroying itself :ninja:

It is just the core that is shit.

The piping has impact yes, but it's marginal in the grand scheme of this topic as the SMIC CORE is the restriction if you decide to try and run 14psi+ - which will kill your stock turbo anyway so why do it? :blink:

i undestand what you mean... but, no im not doing that at all.... and i didnt say anthing about a stock turbo... i was just wanting to know which is a beta piping setup..

im useing what was said as a EG...14psi @ the manifold is close to 17psi @ the compressor

so say, 10psi @ the manifold is close to 13psi @ the compressor ??..... this is what i was wanting to know... nothing about stock turbo's.. everyone knows they will blow at 14psi...

ok.. will changing to cross over piping over the engine for a intercooler. would this have the same effect at the manifold?.. will longer piping work?, or will it be the same as the side flowing intercooler setup.

nice. thanx for the help.. it does look good to me.. what happend to your blitz intercooler... i was thinging of getting something from justjap, its around 499, do you think its worth paying that 100 or 200 more for a blitz.. hows that justjap one going?.. thanx again

That is with the factory FMIC.

Soon as you upgrade to a decent FMIC, you'd be lucky to see 1.5psi drop across the core depending on all the variables (what turbo, cooler core etc etC)

How the piping is setup, is as i said, largely irrelevant.

Wether is goes back through the factory way, or over the cam cover makes little difference.

hey thanx.. i read up on alot of the piping styles.. doesent seen to make to much of difference as long as you dont have sharp bends i guess..

so getting a front mount really does help alot, and gettig one, a decent one, will help drop the lost psi?... thanx again.. im only asking because my front mount got wrecked/front bar, and i poped back a r34 stock smic, car runs different, like it needs air when the turbo studders, wasent doing it before.. so was thinking of poping back a front mount, but wanted to see if its really going to help things.. thanx

Nop i would prefer the blitz, My blitz one broke from drifting LOL , the bottom pipe broke :banana: , The justjap one which is the one i have now i've used it on the track which is okie, but the problem is that the core really crap, mine split open from heat banging on the body of my engine, my honest suggestion is to go for a blitz core.

      Rusty roof repair

      By Duncan · Posted

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      first time swapping rb25det into r34

      By Duncan · Posted

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too

      first time swapping rb25det into r34

      By dingleberry · Posted

      hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy

      SAUNSW - World Time Attack Challenge - 5 & 6 September

      By Keeper · Posted

      Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
