acceleration

[Stiv]

So guys, i decided to do a few acceleration/handling mods to my ts:

- lighter rims + swap from stock 205/45 R17 to 215/45 R16
- intake - i need suggestions
- exhaust - same here
- anything else except weight loss? I will take out rear seat if i go to the race track, but not for normal driving

There are a lot of topics for intake and exhaust for 1.3l, but almost none for 1.8l. What diameter should i use?
And another thing, i want to lose some torque in the low rpm, but want more in the high if that's possible
I already have NST short shifter kit and bushing kit.
In the end, what i want is to be able to go 0-60 in under 8 sec (7 would be nice if possible).

Thanks guys
