im building at the moment an a14 which the block has been decked to 0.005" new hi comp but standard pistons on standard new rods, head is an a15 oval port with gx double springs,standard valves,tomei pushrods and lifters and have individual 40mm throttle bodies with motec m800 ecu running full closed loop lambda controlled. with a wade cam i think number 1069s or 104 will make a decision in the next week or so. ive spoken to a couple experienced engine builders and they are expecting 150hp or near enough to. having said that these blokes said they havent seen an a series with quad thottle injection before. and all up it wasnt that pricey.
