is the downpipe, headers, and pully something i could install myself? or do people usally take it into a shop

 

yeah you definitely can if you have a jack, jack stands, and a good amount of tools.

it would be a big waste to take it to a shop because they charge so much plus its just good experience to actually work on your own car. get a friend to help you for sure, preferably someone with some mechanical experience.

i know from experience that the header and s pipe can be done by yourself but its always better to have someone to help you.

 

ya whats his username?

 

I haven't read up much on the 12lb pulley, but wont that max out his TRD injectors? I thought I have read a thread or 2 stating they had to use bigger injectors for it...

I would go with 9.5lb pulley on the safe side, with a piggyback (don't have to go emanage, there is the AEM F/IC.... you should ask your tuner which he prefers and read up on both first), exhaust (You can save money by just getting the s-pipe back all 2.5"... the bottleneck in our exhaust is mainly the s-pipe anyway.... you can go custom or with either dezods 2.5" turbo exhaust or ptunings 3".... again, your research on what you think), and then a BPV... All that should allow you to hit 225+

Congrats on the accomplishment!!!

Oh and lastly, you could always buy the S/C used, and have more money for bolt-ons :D

The headers and the s-pipe and exhaust can be doen by you but a friend makes things alot easier as i have been involved in some of these installs and one person doing it would suck. The pullies are more difficult i havetn done those but I am sure there are plenty of people around to point you in the right direction if you search.
