With the mods I have listed below, will I be safe enough to get a bigger throttle body and/or Intake manifold and gain hp or am I going to have to upgrade my fuel system first.

 

a new TB does not warrent upgraded fuel system, it will be fine

 

Just my opinion but I wouldn't waste my money on a throttle body. There are a lot better things you can buy to increase horsepower.

 

^ like he said your stock throttle body is fine... now MINE on the other hand has the diamater of well.... something really small.. that is why i am looking arround my area fora Z6 I/M and T/B

 

What size is yours Fiirkan? No pun intended..

 

Navermind i was mistaken i was thinking that i had the same throttlebody as the D15B8, but i guess mine is the same size as the Z6... i just need a new I/M

 

You have me curious... How big is the throttle body.... My guess is 56mm...?
Nevermind I found it...
Here are some others if anyone cares:
b18c1 60
b18c spec R 62
b18a 58
b18b 60
b16a SiR 58
b16a Sir2 / b16a2 60
b16a3 58
b20b/z 60
f20c 62
f22 / f23 60
d15b7 56
d16a6 55
d16y7 56
d16y8 56
d16z6 56
d16a1 55
d16a8 55
h22a 60
h23a 60
ZC 55

 

^ yeah i thought the B7 and B8 T/B were the same till i found that, i know the B8 is like 50mm or something REAL small..

 

So I would be better off just getting an I/M? But, if the new opening to the manifold is like 65mm, wouldn't it be a good idea to move up from my weak a$$ 56mm.

 

bump^ C'mon I know someone knows.
