Mad Max Posted October 20, 2003 Share Posted October 20, 2003 Hey guys, was wondering if you could help me and a mate out. We are unsure as to whether his Silvia (Q) has a CA18 or a SR20. So I was wondering if I could borrow your knowledge and help us out Here are the facts: It says 2 litre on the engine casing. It has SR20 on the sticker on the under side of the bonnet. It says CA18 on the metal stamp next to the import stamp. It is a 1991 model. (I think, it may of been imported in 1991) We are unsure which to believe, the company in which he bought it from said it was a CA18 so it doesnt matter if it is, he didnt get ripped off or anything, we are just interested. Cheers for any help in advance Link to comment https://www.sau.com.au/forums/topic/27412-is-it-a-ca18-or-a-sr20/ Share on other sites More sharing options...

SeriesIIGTST Posted October 20, 2003 Share Posted October 20, 2003 Does it look like the engine below? If so, it's SR20 and 2L, if not, it's CA18 and 1.8L Cheers Link to comment https://www.sau.com.au/forums/topic/27412-is-it-a-ca18-or-a-sr20/#findComment-575282 Share on other sites More sharing options...
dkonig Posted October 20, 2003 Share Posted October 20, 2003 If its a Q, it will look basically the same as the one in the picture, but not exactly, essentially, if its a Q, and the rocker cover is silver then its an SR20 Link to comment https://www.sau.com.au/forums/topic/27412-is-it-a-ca18-or-a-sr20/#findComment-575505 Share on other sites More sharing options...
pentae Posted October 20, 2003 Share Posted October 20, 2003 mad max: Is the boot badge a circle or more square? The SR20's have a circle, the CA18's have more of a square boot badge. Also the SR20's have round halogen lights (99% of the time) and the CA18's have the better looking square headlights. dkonig: Be careful not to spread misinformation.. SR20's have a red rocker cover, CA18's should have a silver one. To confuse tihngs even more, it might be a CA18 with an SR20 Engine dropped in it. But yes, '91 models and above are SR20's.. And no, it would have certainly not been imported in 91.

pentae Posted October 20, 2003 Share Posted October 20, 2003 So with all of the above said, to confuse fellow import drivers, I drive a turbo SR20DET Silvia which is completely debadged including the boot badging and has the CA18 style headlamps.

urbanoperations Posted October 21, 2003 Share Posted October 21, 2003 CA18DE only ever came out with a RED ROCKER COVER, SR20 came out with SILVER, RED and BLACK rocker Covers, Silver usually non turbo, red turbo and black VCT turbo.

pentae Posted October 22, 2003 Share Posted October 22, 2003 Yeah you guys are right.. unfortunately It still doesnt help this guy figure out the answer to his question. If the engine doesnt have a T on the end who cares anyway.

Guest Sphyncter Posted October 22, 2003 Share Posted October 22, 2003 ive got a ca18de red rocker silvia. dont worry about the badging and stuff cause thats no good to ya. you should be able to go from the metal stamp (next to import stamp) because these are meant to be changed whenever engine is changed (duh!) because it should have engine number on it and stuff. i know mine has had a 2L in it at some stage, but its back to the 1.8. check the metal badge, if that says 1.8 then id say its 1.8. as the guys said, without a pick we can't help ya. as for headlights guys, mines an 88 and its got the round globes, not the square!! -Pat And this has been my 2 cents.....
