There are no drop in radiators for the P11 or P10. Guess they figured the market is too small for it, and fitting the B13/B14 radiator is not impossible.

Stock vs Koyo, stock is about 1-2" taller.

Stock vs Koyou thickness, Koyo is huge!

Wohoo the Koyo fit, but it is sitting right on the turbo intake housing.

Main reason is a lip in the radiator support

Used some pliers to straighten it out

Cable support kind of gets in the way
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0248.jpg)
After straightening out the lip, compressed the support as much as possible

Now the radiator sits a lot better

![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0251.jpg)
Not much play room between the downpipe and the core
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0229.jpg)
Radiator hose is a little close to the downpipe, but it's not too bad
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0249.jpg)
The hose also gets slightly pinched since the new radiator is lower and closer to the block
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0278.jpg)
Shortened the hose, the same will need to be done to the big radiator hose that goes to the thermostat
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0279.jpg)
This Koyo will need 12" fans, just like the B13/B14 radiators do. 14" fans are a little too big and wont sit flush against the radiator. I ordered 13" fans, i believe they should fit with minimum cutting.

![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0253.jpg)
Lower radiator support will need to be slightly bent too
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0281.jpg)
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0283.jpg)
Next fun part is the mounts, since the B13/B14 radiators are also not as long, the mounting points will be closer together. I drilled a hole and inserted a bolt.
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0271.jpg)
Getting the bolt in was a little painful since you have to pull out the wiring harness
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0274.jpg)
Custom made aluminum radiator mounts :-P. I needed the radiator mounted as soon possible. You can use B13 mounts with a few alterations.

Lastly the reservoir tank nipple is also further away from the tank. You will need about 5' of 5/16 hose. Just run it back to the reservoir tank and replace the old line
![](http://i160.photobucket.com/albums/t188/covertrussian/Cars/00%20G20t%20KH3/Engine/Cooling/Radiator/CIMG0284.jpg)
Here is what it looks like after you are done. Man I really need to wire tuck!
