Can i use these...
 

Want to start modding my Silvia so have been looking around for parts... found a few decent intercooler's but a few are of diesel car's, does this cause any prob's when using it on a petrol engine. Also can i use the s13 lightwieght pulley's on th s12?

Thanks James

most people seem to fit either the volvo intercoolers cause they are large and cheap or cossy 4x4 ones which are inexpensive too,the s13 has a different crank pully nose to the s12 i think

the diesel intercoolers tend to be small limiting your boost level
bigger intercoolers will cool more efficiently. the Volvo IC`s are good up to 18psi
