Default FP green with no exhaust mods? possible?

Want to go stealth with a stock spool like turbos such as a fp green. I dont want to touch the downpipe/uppipe/exhaust at all. Just want more hp. Could I just drop in a fp green + injectors + intake and tune? Would I have to worry about back pressure? looking for about 330-350 whp. would such a set up be reliable? Should I expect the ringland issue to pop its head? Car has 1500 miles on it as it sits. Budget is 2-3k

You need to do a lot more research.

Best bang for your buck for more power is downpipe and a tune. Putting in a bigger turbo, injectors, and tune, but no exhaust is asinine. You're basically giving someone a pool of water that they have to move from A to B, but they have to use a spoon. An exhaust will allow more airflow. More air = More fuel. More fuel = More speeding tickets.

Possible? Of course it is.

Smart? No, you're a dumb-dumb.

I have to agree, yes you can bolt on whatever turbo you like but the stock exhaust system is going to kill the performance. If you want stealth I would suggest just changing your downpipe to a catted downpipe. Then you can make the power you want without too much noise.

You'll need a downpipe, plus the injectors and fuel pump, a new intercooler, tgv deletes and a turbo inlet at very least.

This dyno sheet was with an FP HTA Green, aftermarket downpipe and the stock catback, but a bunch more parts, like intercooler, turbo inlet etc.:



My build thread is here, http://forums.nasioc.com/forums/show....php?t=2421905 and you'll need mostly all of that stuff.

My advice to you is don't do this on a small budget. You're going to break something or realize you need to spend much more than you thought and end up with either a bunch of parts sitting around for you to get some more money or in the worst case scenario, a broken car that needs an engine rebuild ($$$$) and a new turbo ($$).

edit: you're in CT. Call EFI at 203.748.1115 and see what they want you to install at minimum to support a Green-sized turbo.

I understand and fully aware that dp and other mods would give more hp with a bigger turbo. My question is it safe for the motor to have a bigger turbo and stock everything else except for injectors and tune.

Budget is not the problem. I ran into exhaust smell/loudness with my Evo and am trying to avoid a similar situation. I just want 320-350 without having to touch the exhaust and the only way to get there seems to be a fpgreen.

There are exhaust systems that flow, are quite and have cats. I also keep my wagon on the down low. you can do it on the stock exhaust but it is easier to do on after market exhaust. Stealth is sweet I do that also however it does make things a bit harder.

If you want "stealth", downpipe + stock catback = done.

Research please ._. and check this thread out for more "stealthy" choises for exhausts if you don't want stock :
