hehe would push the intercooler into the engine.... its real tight in a skyline enginebay as it is. with an SR conversion it'd be awesome, but I don't see many advantages in a skyline engine bay with an RB. real estate front to back is real tight in one of those. Didn't really think about the heat rising from the radiator...

Ive been a fan of the open V mount... ie radiator vertical behind the intercooler which is on an angle with a bonnet vent... but the V mount on the R31 is interesting... for race use only I guess.

If you wanted to be a real tricky dicky you'd make the whole thing out of flexible piping and mount some servo's to move the radiator and Intercooler from vertical to V mount according tot he speed you were goin at... :D hmmm now there's an idea...

LoL all the gain you got from the shoter pipes etc, you would lose in tricky electronic gear :P

what if you leave the radiator as is and mount the ic on top of the engine(possibly a sm but thicker radiator to compensate that way the fans can still suck air through the radiator and pull air through the intercoller, best of both worlds?

Like a subaru?

Yep, but the hot air comes up from the radiator and goes through the intercooler and out the bonnet (ie; hot air rises) On its way though the hot air heats up the intercooler.  That never happens with a FMIC, the radiator is behind the intercooler and the engine or electric fan sucks the hot air from the radiator, away from the intercooler.

In a > mount in traffic or stationary, the intercooler will quickly get to 90 degrees, which is the temperature of the air coming out of the radiator.  It will cool down once you get moving, that why it is an OK setup in a race car.  But a waste of time and money in a road car.

Oh and you should see the damage if you have a slight front end tap, makes a real effenn mess. :D

but at idle the turbo is not running any boost. so it wouldnt really matter would it? as soon as you start moving the superior air flow would cool it down pretty quickly. wouldnt it?

Ahh no, the intercooler is still hot, so it heats up the air going through it. Until it cools down, maybe 2 to 10 seconds depending on speed and ambient air temp. :D

This is what i'll be running in the lancer project im working on ATM, however the is no reason that the intake itself cannot be partitioned right from the intake itself, running a thermo fan on both the radiator and the intercooler! separate intake ans thermo's fresh air at any speed to both cooling devices!

OH and whats wrong with running the radiator at the top to stop further heat soak????

i will be keeping an eye on this thread for sure!

GTR-NUTTER - that would defeat the purpose.. they want separate intakes for both devices, so a conventional IC with horizontal radiator would still be heated by the IC before the rad!

I guess because that kills the idea of having shorter piping???

Which brings me to my next question, does taking out that little amount of piping have that much effect???

that could be true, but it would depend on what engine the car was using! if say it was a front facing plenum then the IC on top wouldn't really affect the pipe length compared to below....

however a standard rb25 inlet manifold would best be used with the IC on top, this i pressume wouldn't be the case if going to the length of ">" mounting these coolers!

better response from throttle on/off, and minimal chance of heat soaking the pipes (not an issue really within the pipes only IC core)

But if you have the money to throw around on > mounting stuff, then you probably have the money for better forward facing plenums, and internals, and turbos, etc etc :mad: Either that or WAYYYY tooo much time on your hands.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.

      Jacks that fit under GTR lips that can reach the subframe?

      By MBS206 · Posted

      For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!

      Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
