MAZDASPEED 1.6/1.8L cat-back exhaust ______ HP Gain J-SPEC 1.8 DOHC GT-R Intake manifold _______ HP Gain

BULLFROG Bored throttle body_____ HP Gain

PRM Pro Intake kit_____ HP Gain

PACESETTER 1.8 DOHC header___ HP/ TORQUE gain

UNORTHODOX RACING Underdrive crank pulley 1.8 DOHC_____ Gain

These are the mods that I am planning, just wanted to get some input from the people in the know, about these upgrades.

max HP?
.25 mile times?
0-60?

 

the GT-R intake manifold may help a bit down low, but will hurt top end, as it is designed for a turbo engine, not an N/A engine, it also does not have the VICS.

You have to look at the overall picture of how all these work in unison. don't just add up the proposed HP gain from each item. I estimate the curve to be nice and maybe a 15-20hp gain overall.

 

the mazdaspeed catback is no longer available....i tried ordering one through corksport 6 months ago - they found out it was discontinued

as far as the #'s, i'd have to agree with Darryl
