every jap-spec primera has roller rockers also bluebirds too in every SR version SR18Di, SR18De and SR20De they all are killer engines too, and all have gold rocker covers. although some primeras of the same year also had silver/brushed aluminium covers and all have the intake manifold coming from down low, where as the gold ones have both high and low. the 1.8 has the same exhaust and intake pattern as its 2.0 versions. a common easy mod is to put a exhaust manifold from a 2.0 on a 1.8, and to be straight up you would never tell the difference if you went from one engine to another, the 1.8 is a real good option sure its not a SR20DE "giant killer" but man straight up it is right up there with the rest and the SR18Di with the intake baffels removed (bout 10 litres worth...) it has one hell of an induction roar, i mean one hell of a horny sound, and with a good exhaust, not the sort you guys use but a proper competition exhaust (tuned length) it will easily become competitive, expecially on the open road, heck i wish you guys could hear one of those Di's tuned really well, awsome sound, only a single point injection but they get a hell of a lot more air through them ill post a pic comparing them eh
sweet well ive taken up my space for today i think eh
