aye a seen you driving through camelon while on the phone to enzo when i was out with my mates should be getting a starlet within the next couple of weeks so will try meet up with you one time.
if you can try get a different type of fliter, maybe a k&n or apexi since HKS arent the best fliters. Theres a test people done on the net somewhere, not sure where it is as im not at home.
they aint common round here and the only people i ever see driving them are old people or just people who use them as a run arround. Ive only ever seen 1 SR about near me and a few n/a's but seen more glanza's and gt turbos than anything. At the local cruise theres usually about 4 or 5 glanza's and maybe 1 or 2 gt turbo's. and there just going to get more common and more common in scrapyards since more people are going for fresh jap imports and breaking high spec gt/glanza's
