Message: <blockquote data-quote="spoon" data-source="post: 803277" data-attributes="member: 550">Not necessary to change to P73 head to get more power....in fact u'll lose compression. Unless of course you change pistons as well or run a thinner metal head gasket.One more thing about the p72 head, it has a 60 degree valve angle.... where else the P73 has a 45 degree valve angle. the major weakness of the P72 head is the intake manifold, which is basically designed to give better mid range power....doesn't work that well if you wanna push aggresive cams such as TODA C's or Jun III's . However, the intake manifold can be modded.....as seen in erick's racing (fastest NA in the world 9'sec 1/4 mile time). he is using a P73 head with the dual runners intake manifold (modified of course!)yes. B18C cams are 'wilder' compared to those of the B16A. i think auto and manual is the same for the B18C.so to your question should i swap head or not? Seriously, if you dont have intention of changing to wilder cams now, keep the head! the powerband produced by the GSR actually beats the B18C type R all the way untill 6000 rpms, thats where the type R engines starts kicking. But for daily dirivng, u have a really nice flat midrange torque for your everyday drive wif the GSR head!!I have my other ideas as well....but im not goin to share them to you now...hahahahaaha *hint* yes it involves a P72 head! so go figure</blockquote>

How to overcome weak low end/weak throttle response?

After doing some research, I understand that the sluggish feel (weak throttle response) of altezza is caused by the heavy dual mass flywheel which weighs about 12kg.

So I have been thinking for a while and I know...
