ive searched and read but it isnt still clear to me. if i get a front clip i dont need to buy radiators and intercooler? i just need new fans water pump, downpipe, mounts and drvieshaft for the install right?

stock 240sx radiator
you can use the stupid worthless stock RB sidemount intercooler if you like but I strongly suggest against it

nisilvia

so what it is basicly is that if i get a front clip i should be all set?

nisilvia

dont you have a rb in your car? is it as reliable as people say it is and how has yours been treating you. is it fast? how many miles did you buy it with?

jonpowell

in my old car yes, I sold it
VERY reliable, an awesome daily driver stock...modded its only as good as your tech.
I thought it was scary fast, my father-in-law described it as a go-kart on crack.
roughly 45,000 miles

nisilvia

did you put it in yourself? and if you did when i do mine can i ask you for help?

jonpowell

yes
sure, but dont be annoying!!!!!

Jonpowell, if i use the stock radiator will it have enough cooling capacity for an rb25? Also, what fans should i use if i keep the stock radiator? Flex-a-lites are too large to mount to the stock rad, it says you need a koyo rad for the flex-a-lites.

jonpowell

My S13 radiator with the stock S13 electric fan & the stock R33 electric fan NEVER and I repeat NEVER overheated. It was fine

R34 Racer

I was under the impression that the rb25 and s13 ka had a belt-driven fan that ran off the main crank pulley? Am I wrong?

jonpowell

You are correct.

What you forget is that the RB has 2 extra cylinders than the engine bay you are putting it in and the fan clutch & blade WILL NOT FIT on the RB25 in an S13.

R34 Racer

Sorry if I'm being a nuisance Jon, but which electric fan should I invest in then, if the stock mechanical fan wont fit? Phase2motortrend says that the flex-a-lite 200 or 210 won't fit on the stock KA rad due to lack of surface area.

jonpowell

you gotta put them on the intake side, not the engine side....UNLESS you have the McKinney mounts.

R34 Racer

Ah, thanks. And there's no problem with the fans being to big to mount to the rad?

jonpowell

depends on the fans...YOU gotta research that. Measure the surface area of your radiator, find the area the fans of your choice require and do some math....

(radiator surface area)-(Fan requirements)=X

If X is a positive number, then you are ok.
