Default fp green on modified 03??

I'm thinking about going tmic and short ram as a nice powerful daily driver. I feel like the large fmic was holding a lot of power back, i have a cobb ap so getting a real tune threw my friend from pro motor sports of n.e with the computer could help tune out some of the lag and create a little bit better drivability. I know there will still be some lag but, After doing some research the thought insted of selling parts maybe just upgrading to a more powerful tubro to work with the cai and dr 725. A good buddy said to look into a fp green. The thing im worried about is if thats too much power for the motor, would forged pistons, new bearings and rods be enough or getting a new bottom end? Could selling my motor w/110,000 and swapping for something also be an opption.

Anything would help Thanks

a green would probably only give up 2-500 rpm in spool to that pe1820, which was never known as a particularly fast spooler. the 1820 wakes up at higher pressure ratios as does the green. a good IC is necessary.

the safe route would be to pull your still running motor, sell it, and fold the money into a better build. forged pistons at the least. getting some cams in there would turn it into a monster. i would not go 2.5 block as you have a gearbox waiting to grenade. a big, slower spooling turbo that makes power up top via rpms and cams is easier on the gears than a low rpm torque monster.

Why a short ram? I would think that would loose you power.

thanks guys, after more talk with my guys I figured that the bottem end is just too weak for a big turbo. I'll keep the pe1820 go big top mount and swap the motor in the future any idea what a 2.0 w/ 110,000 is worth?

I am on a green (OG 49lb/min) and enjoy it thouroughly. If i had the cash i would go hta green as it is basically a small 30r (56lb/min), but ideally rotated 30r would be the largest i would go on a stock 205 and trans.

Remember 2.0l will not yeild nearly as much torque as 2.5 unless you get crazy with the timing. Oh and i am on stock trans

Bottom end is to weak for what? 205 pistions imho a hell of a lot better than cast oem sti pistons. The rods are the short comming with usdm 205. Find someone that knows how to tune

good luck on your 205, here's some carnage of my friend's bottom end after a green, made good power 365-370whp on a mustang dyno but his motor had alot of hard miles. It was definitely the rods.

I had a green on my 03 and it is very slow spooling on the 2.0L and not ideal for DD. If you want low lag good hp turbo, consider the Tomei 7760.
