i have a 94 gsr with a different 94 gsr head from an ls-vtec. i took this head becuase my head is blown.do u think itll run the same as b4??

 

did you do any damage to the bottom when the head blew? if the condition of the heads are similar, should be about the same.

 

no damage was done to the block. just a blown head, so i replaced the head. and also slapped on a sk2 manifold. im dissapointed, can it be because of the sk2 manifold? or should i put back my stock manifold?

 

from what i gather, if you are running stock gsr cams, you should stick with the stock dual stage intake manifold or you will loose low end power. only upgrade to a type-r or skunk2 intake manifold if you are going to upgrade the cams as well.

 

if i upgrade my cams, can i still use stock p72?? i ran a chipped p28 by phearable and it feels almsot the same, just different vtec point. and also, will new cams make my vtec hit harder

 

You will need to adjust the VTEC engagement to 5500 - 5800, depending on cams. A dyno tune will tell you exactly where to set it. The stock P72 VTEC point is too low for a large single stage manifold like the Junk2. While you're at it, get some better valve springs so you can get a couple extra hundred rpms in.
