bringing to live this thread!!! Right now iīm boosting to 28 psi with FP Black! I have an agressive tune but according to my tuner something still itīs not ok with my motor!!!

The motor feells good, but in virtual dyno the car is under 400 whp :S

Right now my car is an 11 seconds car, but Evo 4 is lighter than evo 8!!! One more thing, i change valve springs, reteiners, lifters and I always have knock!!!! I made some pulls and all is ok, then I made other pull and see a lot of knock!!!! I change everything in the head, and other things to rule out possible phantom knock but nothing works.,The engine always give me 150 of compression in 4 cilinders!! I donīt know what can happen!!! Some one have an idea??

The other thing, I have stock manifold (ported by me (bad ported)), stock 02 housing (ported by me :S and stock intake manifold (ported by me =) so, I bought a 02 housing external dump tube, MAP short runner manifold, maybe with that I can increse some ponys!!!
