i need a 670mm x 400mm radator to fit in to the space i have made . the radator out of the silvia is the perfect wide ( 670mm) but too hight. is there a better radator to use or get the tank cut down ???????????

N13 Pulsar is good, but you need to make up a crossover pipe for the bottom. Some BMW ones are good too, but if you've already cut out the front panel, then it would be more work.
Using the N13 Langley (4WD) one is also good, but you need to get a EXA FWD CA18 thermostat housing. The Langley one is available on Ebay.

but i could get mine cut down ??????
ill have a look for pulsar n13

The silvia radiator will fit.... I've got one in my ute.
It's all about how you mount it.

I presume you've cut out all the original radiator mounting stuff from the grill area....

Then you just drill a couple of (16mm from memory) holes in the box section looking cross brace in the front of the engine bay.

This will allow the silvia radiator with the standard rubber bushings to slot in..... Sits just right.

i was going to do it just like how you have it in your pic but it looked like it was to high wit the cap on so i was thinking i could mount it under the top bonart brase to make more room for working on motor ....

you'll find its not too high on my motor the rocker cover is level with my cap. and the bonnet clears with room to play.

my rad sits 50-60mm higher than the rad support and still does not hit the bonnet. it is mounted back about 50mm too. you will be surprised how much room is under the bonnet

do any of you run hot with single core radiators? Ive got single cored camry radiator that takes whole front up and still hits 100+ degrees C, twin thermos too. Cores in excellent condition? Yea tons of room under the bonnet, good to have it high so cap high and no air pockets.

Mine gets hot when sitting at the lights or in slow moving traffic during the Summer months.
I have a Silvia radiator (bought brand new), twin 10" thermo fans and an oil cooler.


I have just purchased twin 12" thermos as I believe the 10's just can't pull enough air through the core at low speeds. If this isn't enough I will also buy a bigger single core radiator.

i dont have any problems with mine it usually sits at about 80 and in traffic on a hot day never goes over 100.
