KillerBjt Posted October 15, 2007 Share Posted October 15, 2007 Well today i was trying to figure out what the hell is going on with my fuel delivery and i took my triple Mikuni's off and i looked inside the runners from the carbs to the head and man do they need some porting. I then decided to take a look down the ports of my E-31 head, and i couldent figure out if the intake had been ported so before i left my friends house where the car currently is i took a picture with my cellphone. Excuse the crappy quality, but any input on this would be helpful. Quote Link to comment Share on other sites More sharing options...

JMortensen Posted October 15, 2007 Share Posted October 15, 2007 Try a good light source or a rest for the camera phone. It's not really possible to tell with that picture. Quote Link to comment Share on other sites More sharing options...
e_racer1999 Posted October 15, 2007 Share Posted October 15, 2007 does the port have casting bumps or does it have lines? Quote Link to comment Share on other sites More sharing options...
1 fast z Posted October 15, 2007 Share Posted October 15, 2007 Guys does porting in huts with grinders, so what does porting ACTUALLY mean??? Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 15, 2007 Share Posted October 15, 2007 Looks like the valve guide boss is cut back, and with the color looks like a si-bronze replacement.... Possibly. Quote Link to comment Share on other sites More sharing options...
KillerBjt Posted October 16, 2007 Author Share Posted October 16, 2007 Alright so i went back today and took another picture, plus got some of me porting my intake manifold to match the intake ports on the head! But i am pretty sure the head is ported which makes sense since the previous owner had a machine shop. Quote Link to comment Share on other sites More sharing options...
TravRMK Posted October 16, 2007 Share Posted October 16, 2007 Head looks unported to me. Quote Link to comment Share on other sites More sharing options...
e_racer1999 Posted October 16, 2007 Share Posted October 16, 2007 Head looks unported to me. qft. casting bumps give it away. maybe right inside the port, where it looks smoother; but that could be an optical illusion Quote Link to comment Share on other sites More sharing options...
1 fast z Posted October 16, 2007 Share Posted October 16, 2007 Put it on a flow bench and compare against a stock head. Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 16, 2007 Share Posted October 16, 2007 Head looks like raw casting, what I thought was a cut-back si-bronze vavle guide was due to camera shake blur and rust on the stock vavle guide. Looks Unported now that there is a decent photo available. Quote Link to comment Share on other sites More sharing options...
