Well I was talking to my friend (guy who helped me put the Jspec in), and he was talking about his Rx3 he sold. Turns out it was a 87 6 port motor. He streetported it and it was turbo'd. Car ran 11's on small slicks. I asked him why he wanted to use the 6 port. He told me because it was also higher compression. Would a 6 port turbo really make more power than a stock 13bt 4 port? Oh yea, there was no intercooler and it blew through the AFM. He told me the response was about 5 times better than stock. Could this be true?

Yes, it has been done.

i'd rather have a p-port turbo https://www.nopistons.com/forums/pub...>/rolleyes.gif

Here is a VERY good reason why a 6 port would make more power than a 4 port Turbo Motor:
Port Timing The Aux Ports on a 6 port motor keep the intake ports open much longer. As for a P-Port Motor... The Overlap is so large you would be pushing a lot of compressed air/fuel right out into the exhaust. |
What about having the turbo blow through the AFM instead of before the turbo? Why does that give it that much better response?
