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.

 

Did you make sure that you bled the coolant system and that your radiator fans work? It shouldn't overheat using the D16 radiator.

 

no i didnt bleed the coolant system in fact i should have thought about that. however this is one thing i have never done ever so ( lol at me ) how do you do that??

 

still havent got to the A2 yet got busy doing other things but i will get it done tonight and let you all know how it goes.

 

another question is will the type r integra head fit on the jdm b16 block?? if not how bout the GSR?? i have both just curious.

 

With the engine cold, remove the radiator cap and start the engine. Then let it warm up to normal operating temperature while squeezing the hoses and add coolant if you need to. After the fan has kicked on twice, you can put the cap back on.

 

Yes, it does but you would need to use the Type R manifold when putting on a GSR along with a few other things to make it work right.

 

ok so i ripped into the b16a2 im selling the block there is nothing wrong with the pistons rings cylynder walls the head gasket looks fine and the valves are fine on the head. however the head is a type r so im going to swapp the head onto my stroked b16 and put my skunk 2 cams in the head. than im gonna boost and spray. i really am stumped as to why there was no compression in 3 ? :^\ hmpf but the head looks really good there was no evidence of valve slapp at all the motor has all Gsr internals with a type
R crank so im at a loss. the only thing i can think of is that the timing was off just enough that the valves werent closing all the way. I dont know. but the journey continues. i havent gotten to the coolent bleeding yet but im shure thats what it is. so ill probably do that tomorrow. im gonna pick up a new head gasket tomorrow and were gonna swapp heads on saturday. but i do have one question about the cam timing. when the motor is at tdc the rotor is pointing @ #1 i was told that the veary end lobes on the cams should be pointing at echother and thats how you know that the cams are timed correctly is this right or not and if not how do i know if the cams are tdc. i have skunk 2 camgears and i dont know what marks are what on the cams. thanks again too all who have helped in the past, now, and in the future. this sight rocks you all have helped me so much. thanx 2 everyone.
If You Build It You should Boost It. If its Stock ........ You should Boost It......
thanx again all.

 

You have b18 crank and rods in a b16 block?

 

yup its been sleeved with type r and all comp. changed over with it. according to acuras part # match they are all type r.
