the IC u need has the angled outlets? weird thats a skyline thing not a 180/silvia thing.... anyways its an el cheapo chinese IC. XSpower/ssuatochrome had them listed and i waited for about 4 months of hearing "they're on backorder" I was luckty and stumbled across one on ebay and got it..... these IC's are the same for r32 and r33 (possibly r34 also?)
none on there atm but email ssuatochrome and see if they finally got em in stock
