JDOM310 Posted September 10, 2017 Report Share Posted September 10, 2017 Hi fellas needing help or to be pointed in right direction .

Can a A14 block work withA15 head? If so any opinions on benefits etc pros cons anyone have experience with it . Thank you Quote Link to comment
Cosmonaut Posted September 10, 2017 Report Share Posted September 10, 2017 Crank n pistons/rods are what make A series common block an A15. The heads make no difference as if in an "A14 or "A15" head. Some heads (they all fit any A series block) have larger ports, bigger valves and closed combustion surface area. Quote Link to comment
JDOM310 Posted September 10, 2017 Author Report Share Posted September 10, 2017 In your opinion what would be the best way to get higher performance off the A14 If can't find a A15 to work with Quote Link to comment
Cosmonaut Posted September 11, 2017 Report Share Posted September 11, 2017 Head; read this, a couple of times :-) http://datsun1200.com/modules/mediawiki/index.php?title=Category:Cylinder_Heads Fuel And exhaust; Ditto http://datsun1200.com/modules/mediawiki/index.php?title=Category:Fuel_System As for what I would do..... If you want to follow my thread (http://community.ratsun.net/topic/72491-b210-egi-build-in-the-beginning/page-2?do=findComment&comment=1510374). I am about to build an A15 massaged to an A16, with an A14GX head (JDM only). This will be fueled by an EGI system (1978 A14 fuel injection system, JDM only), but this system will also be modified. The waste will be exiting a stainless steel header (only until I get a hold of an A15 CGI exhaust mainfold) through a 2 inch exhaust system. I will also be running a push through turbo that will be intercooled. To manage this all 4 brakes will be upgraded as well as the rearend. But if not that involved....Electronic ignition (78 B210). Weber carburetor 32/36 with matched Weber manifold. Find a decent head for your needs, port n polish it..only a Nissan head gasket! If you like high rpm's, run dual valve springs. 2 inch exhaust back though a decent resonated n muffler. This will give you a livelier peddle n little more top end. There is a wealth of information in Ratsun and also on Datsun1200.com. 1 Quote Link to comment
