i was wondering the difference in power, if any, between a s14 sr20 and a sr20 from a s15, and then the differences between a red top and black top besides the colors of the valve covers. and which would you recommend. thanks ---

Although recent models have shared this chassis with other vehicles produced by Nissan (most notably the European 200SX and North American 240SX in the S13 and S14 generations, and 180SX in the Japanese market), the name Silvia is interchangeable with the chassis codes.

Just a note on the trannies. The trans thats attached to the S15, 6 speed, is only capable up to around 300 hp. They’re not very strong at all. ---

I remember reading an article a few years ago with a 6-speed handling an SR that had 450bhp, think it was in a Turbo. It’s in how you drive. ---

the one the motor is with is a 5speed… which would be spec s apparently, does anyone know anything more about the realiabilty about the transmissions? 450wheel max at the most would be what im looking at for power but i have other things to worry about right now. i just want to know about which motor would be right for the car just because the availibility of sr parts and i think the rb26 would be a bitch for repair and maintenence ---

imho in the end if your going big turbo anyways all sr’s are the same, your just paying more for a newer motor obviously, so pick whatever one fits your budget ---

yeah ill just probably go with what ever i have the money for since it will eventually need to be re-tuned if i do anything anyways. its also a 900$ difference between the s15 and s14 motor for nothing really changed besides its newer i believe. thanks for the help ---

red tops have the best flowing head… the 6spd only came on the spec r s15. s14 motors were the first with the intake valve timing. if your looking for big power get an rb series motor ---

stick with the sr even if u want to make big power there are plenty of big power sr’s around. besides the rb is heaveir and will throw the balance of the 240 even more off than the ka already does. and like u said its gonna be slight pain in the ass to find parts if somin like ur water pump goes. but if ur just trying to be unquie go with the rb, ohh and the swap is a little more difficult than an sr swap, just putting it out there ---
