i used a scirocco style for afco.

 

this is in my 521. it is a little pricy but highly doubt you will ever need to upgrade.

and i have had new motor mounts made that push the motor back so i do have a little more clerance

i'd like to know what part # hoses creepy cruiser or any of you using along with your choice of radiator. The information would make life easier. btw that is a very nice rad. your using socaldatsun..

[Creepy Cruiser]

For the upper: we use a stock upper and just cut it down.

For the lower: we use is a cut down Gates #21511 (with a small chunk of a stock vw hose to use as an adapter sleeve on the rad side)

i wonder if yall are running into how KAs are notorious for trapping air in the coolant system,

causing you to have to burp the fuck out of the systems.

thats already been brought up earlier

Anyone try a 510 rad modified with a 3 core center? Wondering if it's large enough.

oops my bad

to burp the system you run the car with the rad cap off, then elevate the front of the

car as high as possible. the point of this is to actually elevate the radiator fill neck,

making it the highest point of the coolant system, forcing/allowing the air to run there.

all the while maintaining/adding coolant.

 

i got tired of fucking with that so i just slapped on a breather tank from powered by max/parts shop max.

with those youll never have to burp the system or worry about entrapped air again.

you can get em from psm or no name brands on ebay/similar.

Nope :/    I have a 510 with a 510 radiator that is 3 row (yay previous owner), and I still have troubles at times with heat at say staying in 2nd or 3rd at 4k rpm too long (say going around a long bend). Course my engine is bored 2mm so there is less meat on the block to dissipate the heat (engine is a L18 bored to 87mm)
