2ZR-FE mods

[2ZR-FE]

Hi all,

I bought my Yaris 1.8 SR in December, and I am loving it. However I want to increase the performance, with simple mods to start with

What mods should I be looking at?

What is the best induction kit for the 2ZR-FE engine?

There isn't many mods in the UK for this engine, do you guys know where to look for the mods? ;D

I have a question about the stock exhaust, why does it go so quiet after 4000rpm? I want it to sound louder, is there anything I can do?

I have moved this post from the TS section, as I didn't get many replies

I have looked at induction kits but only found 2 in the UK

Or this one

What kind of hp difference will i get between those 2 kits? Is the typhoon worth the extra?
