hey guys

mate of mine said i can have his old intercooling - for if/when i turbo my NA - it's a hybrid copy usual one seen on here - he upgraded to some crazy trust kit :)

he reckons i could put it on the car now, run one pipe to throttle body and on the other end have it finish in the engine bay with a POD on it - i reckon this wouldn't work as air flow may be cooler but surely the motor wont be able to suck enough air through that distance?

thoughts?

You wouldnt need one as all the cooler does on a turbo car is cool down the hot air from the turbo to intake. I cant imagine the air being drawn in not forced would be anywhere near the temps of a turbo car. But I guess the one way to be sure is to try it out and let everyone know!

Good luck with it!

not just for looks just because if i don't grab it now he's selling to another guy - and i don't see the point of having it collect dust in the shed :P

but i guess with my new bomex front a FMIC would look nice in that big bare space :)

surely it would drop the temp a bit though...

Funny shit, please tell me your not seriously thinking of putting an intercooler on a NA skyline!

If yes, and you know a little bit about cars - please register one vote here for rice thread of the month.

If yes, and you don't know much about cars - trust me, don't buy it and definatly don't put it on your car. If you really have to buy it, just put it under your bed and wait till you bolt a hairdryer to your engine.

Try not to thing I'm having a go - just get some more experience with cars.

BTW: yes, your could get your NA car to run with an intercooler but I would put money on a loss in performance - intercoolers are big restrictions - the last thing you need on a NA engine, it would be purely rice value.

Intercoolers are not as big a restriction as everyone seems to think. Stick something like a hairdrier at one end, (which will burn out with airflow restriction), and you find that it'll happily run, without dying. Have I don't this yes. Why, to dry out a cooler that we dipped.

A N/A engine, will in no way, become "laggy". Commonly associated with turbo cars.... It's not going to be nothing, then, BAM! Power.

The air going into it is the same temp as the air hitting the cooler......

Actually not, the intake air is under the hood (if you're using a pod filter) so it's going to be warmer than the air hitting the cooler, but in all honesty there is no point putting a cooler on an NA car, just make a cold air box and put an feed into it coming from somewhere cool like the air dams in the front bar. My mate has done this and it's gained a KW or 2.

They are a bloody big restriction when you are pumping a whole lot of air through them:

2.5l engine at 4000rpm = 10000l air min = 166L/sec, Unless you have a hairdryer (talking real hairdryer, not a turbo) that flows 166L/sec then your not going to even be able to imagine what sort of restriction an intercooler can be.

your mate actually did this? :confused: or are you lying?

i think timbar32 is on the money here...

the way i understand it is that when the turbo compresses the air, it also generates a rediculous amout of heat. an intercooler is placed in line with the turbo outlet and the intake manifold. hot (and compressed) air from the turbo outlet runs through the intercooler, which is made of metal (good conductor of heat). it conducts the heat so that the metal fins are approx the same temp as the air. ambient air then flows over the metal fins at which point heat follows the change in temp gradient and attempts to reach an equilibrium. essentially the ram air 'draws' the heat out of the metal fins and thus the air inside. on an intercooled turbo car, at best an intercooler will reduce the intake temps to ambient

now, an NA setup has no such heat-generating device in its intake path (ie turbo). so assuming there's the factory airbox and not a rediculus pod, essentially the intake temp of the air being drawn is IS ALREADY AMBIENT TEMPERATURE. thus an intercooler won't reduce the temperature of the intake air because there's no heat difference. all it will do is pose a restriction (which may be insignificant if its a low-powered car)

BUT... for wank factor... an intercooler in conjunction with an electronic BOV set-up and some fake plumbing will make for some entertaining rice.

and if you can convince your mates (and us) that its had a turbo conversion then you should be a politician!

cheers,

Warren.

if you want setup the core in place and leave the piping off this way your core wont be gathering dust in the shed

as for putting a huffer on your hauler ... y not sell it and buy one already turbo'd much much more simple

      What brakes on R34 GTT(Europe)

      Sorry, just assumed that talk of coloured pads meant EBC red/green/yellow/shit stuff. I don't know the DBA pads, but it's a reasonable bet that they will be OK. DBA make good stuff generally. Those 4000 series rotors I linked to are very good. I may well replace the RDA rotors I have with those when required.

      The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
