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:

the one on now is a Just jap one.. some cheap chinese shit still works good!

i would prefer the blitz one but

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.

hey, thanx for the tip about the piping and what intercooler... that big faq was handy.. and good to know its beta 4 me to save a little more for the blitz.. lol at drifting and the piping, it does go low :O . thanx again

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
