B18C JDM P72 GSR - JRSC build - NEED INFO!

My biggest idea!

yeah, Ive read trough first 5 pages today ... still lack of time, and seen those aftercoolers air to water cooling systems being used on JRSC intake manifolds to cool the air down... but I came to conclusion - its not cooling the air down as much as it could anyway... I'm thinking of making a project of my JRSC, weld cooling camera the very same way as LHT did, but before I weld this baby on I must implant A/C rad inside of it so it would have an impact to ICE cold A/C radiator while impacting to water going around it, which would cool down air in intake manifold after charger as much as ice cold when I hit AC button on! Would need to remove AC piping from the cabin of the car, and re-route piping to aftercooler housing where's small A/C rad would be welded in..

Other more simple idea came in to my head was to place such tiny A/C flowing rad inside of intake manifold but this could cause fatal failure as it would produce condensation inside of IM while air is non-circulating, lets say after a road trip you shut it off and condensation drops would soak in to the intake ports/cylinders - next time cranking up the car would be a fatal failure while water in cylinders... wouldnt it possibly happen?

or another idea was make an intercooler for the system as simple as - make a double sided partition wall in a middle of intake manifold and make out and in ports for front mount intercooler piping!

picture that I just quick drawed is just an Idea I am going after, but the out port surely has to be welded from inside of the manifold directly from the port where sc connects to IM so returned colder compressed air could utilize vacums and sensors of the manifold, in this case there's no need of partitioning the manifold just making direct out from the supercharger to intercooler piping!

First off you can re-drill the jrsc manifold to fit the gsr head, the b16 jrsc manifold and gsr jrsc manifold are made from the same casting, I think you'll need to plug a coolant hole, it has been done before look on honda-tech. Next, I would only use an oem head gasket, 3 layer. If you are not going to upgrade your injectors and fuel pump, you will at least need to upgrade your fuel pump and run the jrsc fmu and retard the distributor. The better option is to do the pump and injectors and have the car tuned. The jrsc blows hot air, it gets too hot around 8 or 9 psi, if you are not going to push the charger that hard you should be fine without an after cooler or water or meth injection. The JRSC thread on honda-tech has lots of info, if you want to know anything about what you should do read through that thread.

thanks man, checked all bolt and holes pattern - will be drilling it to fit upper bolts, and will be tapping of the coolant hole.

getting this polymer gasket of ebay
Thermal Polyster Gasket - CLICK ME

IS IT ANY GOOD OR BAD OR SHOUL i GO hONDATA INSTEAD RIGHT AWAY? iT CLAIMS TO BE MADE OF THE SAME MATERIAL...

Just seen that you replied to this. I am not totally clear on what you are saying about the AC method of cooling the charger, to me it sounds like you are basically talking about a Killer Chiller, using the ac to cool the water before sending it into the charger manifold. Your second idea of running a front mount has been done before, and honestly I haven't seen any done that produce better results than the LHT setup. I currently own an LHT JRSC b20vtec, I have tuned and helped on two other LHT jrsc setups, and 2 other none-LHT jrsc. The LHT cars have always been faster, even at the same boost level. I have spent lots of time trying to figure out a way to get more out of the JRSC, it is maxed out at 300hp on these honda motors, aside from some major custom fabrication I don't think there will be much you can do to improve on what has already been done. I'm not saying there is nothing, but theres not a lot. And your question on the gasket, all the ones I have seen that are like the hondata ones, work the same as the hondata ones. The real improvement for this kit is to get eaton to make a ccw spinning tvs1320 and adapt that to the LHT manifold. If you get that done let me know lol jk

I am thinking of running directly a/c (freon) by a standard car's a/c compressor thats already there trough the housing of IM built similar way to LHT and planning to make similar design cooling case welded on around the rotors housing to run the same A/C trough it to cool it down, just by a push of the button from the inside of the cabin ;)

could it be too cold by any way?? - in a matter of condensation appearing inside of the sc casing due to high temperature differences or it shouldnt happen? what do you think?

Assuming that logic provides some gains, wouldn't those gains be counteracted by the fact that you're now putting more load on your engine by making it run another belt with the A/C on?

Running the freon through cores in the manifold is the same idea that I was looking into, the issue is that your ac pump is not meant to run, on, up at 8500 rpm. That is why people use the killer chiller so that water is cooling all the time and ac gives the extra cooling to the water when you are not up too high in the rpm range. This might not be as much of an issue for a drag car, if its a one hit wonder, you would run a very large reservoir of ice water and have a pump set to cycle it only once in a 12sec time period, turn it on before the run, then drain and fill before the next pass. Condensation could be an issue but there are ways to take care of that if you are planning to make this all custom. I think you would be surprised at the difference you will see from an lht cooler. By the time you get the extra cooling over the lht, and then have the extra drag of the ac pump, I think the hp gains would end up being little or none.

i believe as for daily driven car the factory a/c compressor powered by factory belt wouldn't rob too much hp and torque at mid range and low range rpm's... would it? I cant feel much difference with a/c on or off when driven daily,,, by the way, If I'd tune car for lower end torque and power rather for higher end power, I'd say a/c compressor would do a very good job wouldnt it? I could also do the killer chiller thing but have a very little idea how its done... is it kinda rad with two cores one is powered by a/c and other by water? Or how's that?

If I was to do this A/C transformation - interior cooling is going to be removed and piping shortened, plus A/C rad would be used from EG civic / smaller to compensate capacity

one of my good friends has a supercharged em1 si with a full votech kit, he has a custom made aftercooler and doesnt have any overheating problems

yeah but thats a bit different, its jrsc we're talking about , vortex is turbo blower based high eficency blower with different design and characteristics and specs, so its kinda bit out of topic...

hey all... so after all wont be doing this on my GSR... due to icy roads and snow crashed my teg week ago... will be parting it soon or selling complete soon... anyways, got meself 00' ITR and it will go on to it but this move have caused abnormal dellay in building anything there so... will be in touch

Sorry to hear about your teg, but it sounds like it worked out for you in the end. If you decide to do something different using the ac let me know I would like to see what you end up with.
