Does anyone know the cfm of FD OEM fans?

 

Also make sure you have a proper shroud when using the SPAL fans...

 

So thank you all for contributing to this thread. It helped me a lot when making some decisions about installing the Greddy V-mount. And a special thanks to JP3 Motorsports for making the very cool RX-8 condenser retrofit brackets and AC lines!!!

The Greddy kit is nice. While it technically is plug and play in a sense...you do have to mess around with a few bits when installing the kit. I have the version of the kit where the instructions say you have to pass the relay box through the frame and install it upside down in front. Apparently later versions of the kit have a different solution for this. Second thing that caught me by surprise is that Greddy does not provide all the necessary coolant hoses! Considering the price of the kit you would expect to get a complete hose kit to complete the radiator installation. Greddy wants you to reuse your OEM coolant hose and cut it at a specific spot and use it with their kit. Considering my OEM rubber hose is probably 20 maybe even 30 years old...reusing was not an option. So I decided to new silicone hoses. Also the silicone couplers and one single 90 degree coolant hose that Greddy provides are blue, and that does not match my color combo, so I went with all black.

I added a bunch of gasket sealant to the bottom (now top) part of the relay box.

 

For the radiator outlet I used a 90 degree silicone elbow (same as what Greddy provides in the kit, just blue), then goes the aluminum S pipe provided by Greddy which is then connected by a 67 degree silicone elbow to the waterpump neck. This all fits nice and snug.





For the radiator inlet I used a 90 degree silicone elbow, a 120 degree 1.5" CX racing aluminum pipe as mentioned previously in this thread by marksae. The reasoning for this is to get as much clearance for the turbo intake as I can (I'll explain later why). From the 120 degree alu pipe I just added a straight silicone hose up to the thermostat neck.







I added some thick adhesive backed foam to protect the silicone hose from rubbing on the metal

 

For the fan extension I went with the optional Greddy fan extension harness...and since I am using the later spec/RX-8 fans (which use a different gray connector) I ordered a connector pigtail adapter from do-eng from Japan. Way to expensive for what it is. I was just lazy and didn't want to splice and mess with the OEM harness/connectors...

 

I'm using a BW 7670 on a Turblown shorty manifold and for the turbo to IC connection I used a 2" to 2.75" 90 degree reducing elbow. From there I used a CX Racing 30 degree 2.75" aluminum pipe (which I cut to the correct size), part number PIP275-30...and then finally a standard 2.75" silicone coupler to the IC.

because of strict road regulations in Croatia I cannot have an air intake filter exposed or visible. It has to be in some kind of air box or hidden from sight as the guys at the yearly technical inspection will not like it. So I'm doing some mock ups on how to route the filter out of the way and hide it with some sheet metal. In the mock up on the photos I'm using a 3.5" 45 degree silicone elbow out of the turbo...then a straight 3.5" aluminum pipe followed by a 90 degree 3.5" pipe which connects to air filter.

The routing is perfect, it does not interfere with the JP3 AC lines, and the air filter sits right above the AC condenser and the filter will be exposed to nice cool air from the front of the car. I just have to make some brackets to hold everything tightly in place, and some sheet metal to hide the filter. Or maybe I make the whole piping from aluminum...instead of using the two large silicone elbows...not sure yet. It would look nice to have a wrinkle black powder coated aluminum intake from the filter to the turbo...

 

One last thing...along with the amazing JP3 AC line kit and the RX-8 condenser brackets I also love their Greddy v-mount intercooler tool tray. Not only does it protect the intercooler fins when working on the car...its actually functional to leave tools on it when working on the car. The other day I has a few sockets and wrenches on the tray and its just great. So simple...but very effective. I think I will actually keep the tray in the car with me at all times haha

 

Can you share a link to these please?

 

Very good post @Mardanov, I'll be installing the Greddy Vmount kit soon as well. Do you have any pictures showing how close the OEM dual oil cooler lines are to the radiator? It seems like it's a pretty tight fit.

 

I am installing this kit currently, no issues at all with dual oil cooler line clearance.

BUT - My factory series 6 spot lights don't clear the lower radiator tank, also the factory air guide doesn't fit on without hitting the radiator also
This sucks cause I bought a brand new series 6 bumper skin and wanted the air guide fitted to stop the bumper mouth flopping around... (I assume u need to air guide for it to hold its shape, most bumpers I see are all warped in that area from people removing the guide)

I haven't seen anyone else comment that they needed to remove the air guide or spot light fitment issues.. (even the instructions don't mention removing the air guide, its just assumed from the pictures I guess)

Not an issue with a series 8 (99) bumper skin I guess..

But I wasn't able to buy directly through them, so I went through Jesse Streeter. And I just noticed they increased the price...

 

@Spalato



How did you get a 6-rib RX-8 compressor? The ones I’ve seen are all 4-rib, which is why JP3 recommends a 4PK1015 belt, but you're using a 6PK1015 belt wtih a 6-rib compressor. What kind of magic are you pulling off?

 

Haha good eye dude!

I’m actually not using an RX-8 compressor, rather a Toyota MR2 AC compressor (DENSO 4711426 - SCSA06C) which I bought from rockauto.

Just to be fully transparent, there is very small parallel pulley misalignment when using the MR2 compressor, however it’s a non issue. My mechanic friend assured me that the misalignment is within acceptable tolerance for serpentine belts.

So far it works great. No belt chirps or anything else that I notice. And the AC is nice and cold, like its a brand new car.

The MR2 compressor bolts on to the JP3 brackets perfectly. And the JP3 AC lines are plug and play with it as well.

 

So I'm not the only one who didn't want a belt with less ribs. I dug around and retrofitted an aftermarket pulley for an SCSA06C to the Rx8 compressor and got the offset very close. It is in spec for the belt length per the gates belt alignment specs. I've run this setup two summers now. It aligns better with the Race Only pulleys compared to RE Amemiya pulleys I had on before (PS pulley stuck out more). I purchased this one https://www.aliexpress.us/item/2251832722867570.html. I'm pretty sure this converts the Rx8 compressor to the Corolla (non-US model)/MR2 spec. This winter's projects include installing the Greddy V-Mount to be on topic for the thread. :P

 

I'm also installing a Greddy vmount this winter, to stay on topic

I'll go this route since I bought an OEM RX-8 compressor from Japan, which wasn't cheap. Was it as simple as unbolting the 4-rib pulley and bolting on the new 6-rib pulley? Is there anything I need to be aware of before I start? Do I need any extra hardware?

Most importantly, did you have to modify the electrical connector for the 6-rib clutch/pulley to fit the FD harness?

Thanks!

 

Cool stuff dude! I read about you doing this in some other post, I'm pretty sure it was you. But I was not sure how easy it would be to swap the clutch pulley. BTW thanks for the link.

Congrats on going the Greddy V-mount route. Its such a great kit. My IAT's have significantly dropped and I still haven't added any special ducting to the IC and rad.

Interested in this as well!

 

I'm running the Greddy V2 Kit with the @JP3 Motorsports battery relocation kit. See the picture below for fitment. Honestly, I think it's fine since there's enough space for the loom to pass through. I'll add some foam around the edges as a precaution, but for anyone wondering, here's your answer.
