Hi guys got myself a intercooler package at VMS and just thought all you r33 owners would love to see some pics of the work that VMS have done. This package has made a once sluggy r33 into a bullet and still more mods to come.

VMS is located in Footscray, Melbourne. See David or John if you would like a intercooler package. Just tell em Amit sent you.

Heres the pics below, Comments please.

well this was custom installation and stuff around the $1600- $1800 mark. But its worth every cent when you hear the intercooler sound and when the car keeps on pulling you back with boost never dropping.

But they have other packages and cooler sizes going for $1200 - $1500 installed and tuned.

I think they split into two pipes just after the turbo so that two pipes go out the engine bay (out both the original send and return holes of the factory cooler) and into the new cooler. From a flow viewpoint, i can't see that splitting it can be any better than one single pipe.

When you split it so close to the turbo, the air effectively fills double the volume, which (when fluid expands to fill a void) will cause a pressure drop. So now we have less pressure (but more flow) along two pipes, with added turbulence at the split (remember this is why when we have a separate wastegate dump we join it back to the exhaust a fair way down from the turbine so there is no turbulence). Compare this to the pressurised flow of a single pipe - higher pressure, but no disturbed flow or turbulence until it reaches the intercooler.

So when the two pipes reach the intercooler, the flow does not have to distribute itself as much inside the end tanks, and it should in theory flow much more distributed across the IC core. However, this is where fluid flow research is at its best - i am sure that HKS, TRUST et al have done hours of flow testing to ensure their endtanks distribute flow evenly across the intercooler core. Many companies both local and in japan believe that this is the key to a cooler that flows well, cools well and does not restrict flow too much - end tank design. So now the single pipe IC has reached the cooler, and if the endtank is designed correctly the air will distribute across the core (with a fair amount of turbulence. This pressure drop and turbulence will occur with both styles of cooler.

So the charge of air passes through the core at a lower pressure and is collected at the other endtank, reducing the volume (to outlet pipe volume) and hence re-pressurising the air. Now what i am saying is a well designed twin entry should perform as well as a single entry cooler, but there is more scope for variation. This system would work better for a very big turbo, as it will keep pressures up and air flow speed up in the twin pipes before the cooler.

      I mean the other day I had to walk someone through diagnosing why their timing belt was walking off the cam gears. At least one of the issues was a bent tensioner stud. Local mechanics have found runout on the CAS mechanism causing weird failures. I'm also no saint here I've documented some of the things I've had to learn the hard way. Something I discovered recently is that my CA emissions catalytic converters weren't even welded correctly to align the downpipe to the main cat and they tossed the support bracket that goes from the transfer case to the downpipe to support everything there. I spend a lot of time chasing down these decidedly unsexy problems and the net effect is it feels like I never actually get to the original objective (flex fuel, VCAM, oil control, cooling, etc).

      At times with how you make everything sound, all I imagine Americans doing when they see a gtr is standing there looking at it and bashing it with a gun like how a caveman would with a club and hoping it fixes itself

      I think this is just a product of how the US market works for this stuff. Shops are expensive and there's no real way of knowing what kind of results you're going to get, people don't really have the institutional knowledge. I have heard too much at this point to really put faith in anybody "full service" except maybe DSport and they aren't really a full service kind of shop. If you go to the right place I have no doubt they'll get it right for you. Some locals have set it up right but the cost really is nuts and even now they're still fighting issues. And you know I'm a crazy person who thinks things like twin scroll, relatively short low-mount cast headers, PCV recirc to intake, recirculating BOV, right-sized for ~400 whp, MAF load, validating all of that to a standard comparable to OEM test programs, etc are relevant. For what it's worth, multiple local owners at this point have been stuck in a perpetual cycle of blowing a motor -> getting someone to rebuild it -> some missed detail causes the bearings to wipe and spin just outside of break-in mileage or drop valves or some other catastrophe -> cycle repeats. I usually only find out about this because I'm perpetually helping random friends with diagnosing car troubles, Skyline or otherwise. The single turbo stuff if I'm honest is mostly secondary, it just doesn't seem to achieve the numbers in the ~2000-3000 rpm region that I would expect given the results I've seen here or in Motive's videos. I don't really know what we're missing here in the US to be causing this. Lots of people like to emphasize the necessity of finishing the project first and foremost, but I'm not made of money and I can't afford to be trashing a 15k+ USD engine build with any regularity. Or spending my relatively limited garage time these days unable to triangulate problems because too much was changed all at once. Also, even if it isn't a catastrophic failure I would consider spending the cost of single turbo conversion with nothing to show for it to be pretty bad.

      So whats the deal with the porous block VR30DDTT

      The water pump is know to leak as well. So if the coolant is low checking that first as well as hoses.

      Reading your posts Josh, sometimes I feel like I've gone in a time machine back to the 90's when everyone was doe-eyed and figuring things out for the first time.  I've lost track of how many single turbo GTR's I've seen on track that haven't burnt down lol. Everything has been figured out a long time ago. These things are at the point now where its essentially turn-key to go single turbo.
