When did they start putting 1.6 Vtec Motors in Civic SI Coupes?
I believe it started in 1994. Is this correct? Prior to tht they were just 1.6 SOHC engines..right?
Please help me! I've been called some pretty nasty things today for asking this question..but I need to know! 
The truth must be told!
Hmmm.... Let me see if I remember. I think your SiRs are our Si's. And your Si's are our Ex. So 92 is when the 1.6 SOHC VTEC started for the 5th gens. Then the SOHC VTEC valve covers started in 94-95 for the USDM Ex/CDM Si. Someone please correct me if I'm wrong.
Also the Del Sol's got the 1.6 DOHC VTEC in 94-97.
