Most HP per $ w/o going FI?
 

Picked up my Argento FRS 2 weeks ago, completely stock w/ a K&N drop in. I have about 750-1,000$ for my first upgrade, I was thinking OFT but, I'm not completely sure as to what is the best bang for your buck in terms of HP/Trq. I should mention that I am going to go with mostly weight savings exhaust eventually (Titanium from frontpipe back). Any input would be appreciated, Thanks!

E85.

skip the bolt ons. you'll make more power on E85 alone, with OFT.

OFT + E85 Tune which is free :) then next in line is a nice UEL Header. Don't waste money on a TI front pipe. If staying NA everything after what I mentioned will yield very little gains.

What he said above. Then just enjoy.

Do I need to purchase anything to go E85? does it require different injectors or anything?

you need to purchase something like the OFT, and reflash for E85. no injectors needed for non-FI applications..

search. tons of threads already in place about this. don't waste money on bolt-ons.

Whats hp/power etc.., diff with e85? Any data?

SEARCH.
No data, but it comes out to about 10-15% more power, 20-25% less mpg, and depending on location, about 20-25% cheaper. +/- a couple percent.

Seattle area is ridiculously expensive. They charge more than the cost of premium for e85 :(

Tons of it in the software tuning forum.

I vote for an engine swap (v8)

Also, do a lot of research,
You have to consider noise levels. Certain things will make your car loud as hell, a set up with a UEL header, catless front pip and catback will be stupid loud!

Do a header first. Yields more than stage 1 with oft. Then get oft for stage 2 map to maximize header.
