76649, Just bought header and high flow cat.
Posted by jdpilot, Jun-27-04 01:53 AM
I am just pounding out the installs lately. She has been sitting for a couple years stagnent. Its time to finish her. I just purchased a brospeed 4-2-1 header and a random technology stainless high flow cat! WOOT! Those should match up nicely with my thermal. My recent installs have been an ARD P&P mani with 57mm TB, Neuspeed firewall bar and UDP! After I get these final exhaust pieces on, Its AEM cam gear and SAFC time with a 50 shot n20 (polished bottle of course). I am stoked to see what I run at the track!

Hey that looks exactly what i want to do, except i am getting a race head, crane 0012 cams & cam gears as well lol.......What do you expect to run/whp? I did a thread and they said w/ the 50 shot i would be looking at 190whp is that off?

190 seems high. We are like 120 or so stock. But then again, with your head mods, your prob not too far off. I'd say like 175, 180 at the MOST! I am not even sure what I will run since I won't have the head mods you have.We'll just have to see!

so with: Crane Cams 0012 (maybe 0016 heh), aem cam gears, p&p intake manifold, race head, 55mm tb, cai, header back exhaust (straight pipes), 4-1 Header, udp, ngk one range colder plugs, msd wires, afc- II (tuned) and a 50 wet shot and 190 seems high?

lets see, the cams will give you a little boost. 5-10 hp prolly throughout the rpm range. the tb won't do anything for hp until your boosted really, it gives throttle response i would say. the cai would give a max of 10, the header gives you about 1hp, the catback about 8 or so, udp about 10 max, ngk=nothing, wires=nothing, afc=5hp maybe and 50hp n20. so, i'd say 190 isn't unreasonable. tell us how it goes. if i am just dead wrong on any of this, let me know.
