ok so I did a compression test on my B16 A2 and all held 150 but # 3 so I yanked the motor and replaced it with my jdm B16 Sir motor the motor has a stage 2 crower stroker kit with a transfered skunk 2 turbo intake manifold 72 mm throttle body sai and nology sp wires. i transfered my distributer over to convert from obd1 to obd 2 and the engine overheats only when im at idle for a while (and for a while i mean just a few minutes) i changed out the thermostat and the housing and it still does it. I am running my stock D16 radiator so i thought maby that was it. if everyone concurs to that than i have a question. now i know that your all gonna say why dont you just go after market because thats what i would say about it hover i dont have the extra cash to do that right now. so would it work if I took 2 radiators (these are the little 1\2 radaitors that come in the D series cars and ran 2 hoses t connected in to echother for the top and the bottom would this work. or is it even my radiator causing the problem. also i think this engine has a Gsr head with stock si camshafts my other motor has skunk 2 valve train in a type r head with skunk 2 stage 2 camshafts and skunk 2 cam gears Im thinking about swapping cams due to the lack of power in the jdm cams. is it easier to just swapp heads or to do a cam switch?? 9never done cams before) Im gonna pull the head tomorrow to attempt to figure out why # 3 had no compression Im hopping that its he piston rings are aligned and not that the valves are bent or somthing horrable like that. if its the rings than im gonna swapp the orig. B16 a2 back in and ssell the jdm. I built the jdm motor all motor with 12 psi substainabality <- I think thats a word and the A2 is fully built for Turbo only application the motor has been close decked sleeved with pistons rings rods crank yada yada yada its all been flowed and ported its a quick little 4 banger but # 3 wants to ac a fool so ya any whoo ill let you all know how it goes tomorrow after were done with it all. let me know what you all think about the cooling issue. thank you in advanced.
