greddy intake mani question

[xsublimefrekx]

i am thinking about getting the greddy intake mani and i was wonderign if i get should i upgrad my throttle body to like the q45 or not. any ideas expected thanks.

its not really needed, how much power are you going for?

Q45 throttle body is overkill. The S13 throttle body is sufficient.

i will be pushing a large amount of power around the area of 400 hp and up.i have the whole bottom end built, the top end built, a t60turbo ,upgraded fuel pump, 720 injectors, AEM EMS, 3 inch exhust and all the other little things.thanks for ther help

if your gonna be around 450hp then the intake mani will help a little but there will always be a better way to spend $350. the q45 tb is still way to big. if you want a larger tb i think the ka24de tb is a little larger then the s13 tb so thats a relatively cheap upgrade.

what would you think i should spend the money on then?

[SR 240Z]

stock throttle body is good enough for that power, greddy intake manifold or stock manifold being port matched to the head would be good also

get the tb and mani port matched...or just save the 350 for time on the dyno

This may be false info, but I was told that you need to use a q45 throttle body on the greddy mani b/c it was made for it. I was told that it was made to utilize the q45 tb instead of the stock s13 one. .........Thats what I was told when I called intense motorsports and asked about it. Its been awhile back though

False info you got. Q45 you'd need to bore the opening much larger and weld. That = NOT made for the Greddy intake manifold. Looking at mine, the s13 throttle body fits perfectly *gasps!*.

thanks for all the help guys i think ill just save the money and probaly do some dyno time.
