Big crossflow radiator

[Fahaka]

Wanted to share a bit of information here in the national board about my radiator install.

This is for a SR (inlet and outlet positions are perfect for an SR, KA's will require custom plumbing) and this install is on a s13 although it will work for either s13 or s14.

This radiator is a crossflow type with endtanks on the sides and the area is huge. I haven't done the math but the manufacturer says they are good for up to 600hp in a race application. They are manufactured from aluminum and they do require some trimming of tabs to fit properly (so if you are afraid to cut on your new radiator, or don't know how, do not attempt).

1. First I had to cut the cooling finns off of the bottom of the radiator, it is really only a 3/8's inch tab so it won't effect cooling, and it really is necessary to fit.

2. Make some custom mounting tabs, I used some aluminum flatstock and just bent it in a vice for now, but I will redo these with some extruded angle stock later, I think the current ones are ugly as you can see in the pictures, but they work. You will need four tabs total. The side mount tabs (that come welded on the radiator really didn't line up with anything, so I just used two on top and two on the bottom. I mounted the radiator with the tabs from the top and the bottom at the radiator core support.

The radiator is a tight fit, but with a little wiggling and some finesse it will drop right in. You may have to do this several times while fabbing your mounting tabs.

3. Once the radiator is in mount it and and use samco or equivalent radiator hoses (I did have to trim them slightly as this radiator is really thick).

4. Finally, you will need to cut a small hole in the hood support for the fill cap to clear. I used a cutoff wheel and some aviation snips.

One other note, this radiator did not come with a petcock valve installed for draining purposes, so I will just have to pull it and have one installed at some point in the future. For those who would like to have a petcock valve, any radiator shop can install one.

This radiator cost me $380 plus $5 worth of aluminum flatstock and a couple of hose clamps which I already had.

Let me know if you are interested in this radiator and I can point you in the right direction-Morrie

Time to get yourself some good electric shrouded fans, or put a stock shroud around the clutch fan.

Your radiator can be the best thing in the world, but if their isn't good airflow past it, it won't do anything.

does the SR get a lot hotter than the KA? Because i've seen 500whp+ on stock cooling system with a KA-T...

Electric fans will eventually make their way in. However, as it sits right now in Phoenix rush hour traffic on the freeway nearly standing still for a 45 minute commute to Greg's house and it didn't move above 210F...

Sure I've seen that too. Technically 500hp on an SR needs the same ammount of cooling as a KA. Just because you have seen 500hp KA powered cars with stock cooling systems doesn't mean that they are adequate. I rode in Mike Lee's car when it was 500+hp, and it too had stock cooling, but after a few hard pulls it would overheat...

Sorry for the delay...I wanted to get approval from Greg before I named any names...

I purchased this radiator from Dave at Arizona Z car...(480) 844-9677 tell dave you heard it from me...

thanks I'll be sure to tell him do you know what the weight is?

I don't know I didn't weigh it...it is light though because it is aluminum...my guess would be around 15lbs...

thanks
