By the mods in my sig, do you think I sould get bigger secondaries?? My intake is still all apart from the porting, so I wanted to know now b4 I put it all back together. The porting is VERY conservative, probably only like 2-3mm out of each runner. But with intake and high flow exhaust I just wondered if I would be leaning out at all on higher rpms. These are all the mods that im doing, im selling the car, so future mods arent an issue. If I do, what size? Thanks.

Get an air/fuel ratio gauge. That will tell you everything (well, almost everything) you need to know. Autometer makes a fine A/F gauge for ~$50. If your injectors are relatively clean then it should be fine.

If you're selling the car, don't worry about it. 4x460cc is enough.

You shouldn't need larger injectors on a stock ported N/A motor. You could install an A/F gauge to make sure, but I doubt it.
