I don’t see how he got own3d really… Anyway, google is your friend. Or in this case, I am your friend. Redtop = old - '89(?)- '96 Blacktop = new - '96 onwards ---

Isn’t a redtop a s13 with a T25 turbo, and a blacktop an S14 with a T28, and Silver top an S15 with a T28 and VVL I believe? ---

no there is s13 blacktop and s14 blacktop the main difference is just the colour of the top, and the age of the engine. blacktop is also a couple hundred more $ more expensive aswell ---

Blacktop IIRC has lowport injectors but that might just be on the S14. ---

I believe S13’s are the only highports, and S14 and S15 are lowport. I’m not too knowledgeable on Silvia DET’s, but am on the Bluebird, GTi-R, and Avenir. ---

The S14 blacktop can be distinguished by the hump at the end of the valve cover. The S13 blacktop is flat. This is the S14 SR, notice the back end of it. ![http://store6.yimg.com/I/phase2motorsports_1770_14542231](http://store6.yimg.com/I/phase2motorsports_1770_14542231) The S13 SR blktp… ![http://store6.yimg.com/I/phase2motorsports_1770_17625462](http://store6.yimg.com/I/phase2motorsports_1770_17625462) **Pics courtesy of phase2motortrend** ---

This post is wrong for so many reason… FAQ section is for ANSWERS TO Frequently Asked Questions… not for posting questions. And second, there are 4 million posts on SON, and every other Silvia/Nissan board about different SR20DET motors. ---

Damn it, why do people keep posting questions in FAQ & How To. :squint: If you checked the “Important Links and Articles” sticky, you would have found the answer already. [http://forums.son240sx.ca/viewtopic.php?t=3965](http://forums.son240sx.ca/viewtopic.php?t=3965)
