Have you hit 200whp NA?

[ultra]

Intake + intake manifold + headers + exhaust + tune...maybe there is hope.

Combined with some basic weight savings, could be phenomenal.

I hope to get close in the spring when I install everything and get tuned. I'm going with a works air filter, avo inlet, borla uel headers and nameless exhaust. Oh and that super oil haha.

I dunno, haven't seen many actually released except Agency power.

And we still haven't gotten that drink yet LOL

Damn, as much as i want this car, this engine doesnt seem to respond to mods like my current k20. i guess i will wait to see if subaru really unleashes more power through intake/fuel induction changes in the next couple years. lets hope for atleast another 20 hp while getting rid of "the dip."

Is there an easy/safe way to tune this car without voiding warranty?

This has been discussed, but dealerships can't see how many times the ECU has been flashed. As long as you flash the stock tune back before you need to take it in for any service work.

The lack of variable lift compared the to the k20 kills this motor. People joke about vtec but it's actually a pretty cool technology still. You can get rid of the dip with aggressive cams but then you'd have a torqueless wonder at low rpms like the b16.

How so? We are seeing 30+ whp gains on E85 tune alone. Most SI's that I have seen with full exhaust, header, intake and KPRO are netting just a tad over 200whp. That's not far off at all. We haven't even seen what this engine can do on cams yet. So its hard to say at this time.

What are you talking about man? It's worlds apart. Full intake/exhaust/tune with our cars is down 20-30whp on the k20. That's a massive difference. Let's not talk about e85, it's not an option for most of us. Even still, the k20 on e85 makes more power too.

^^ This.

I had an 08 Si before the FRS and I will say, I do miss the VTEC. But still I'm curious on how the FRS will be when I get it tuned. Out of the dealer, this cars torque curve is terrible to say the least. I guess it comes down to MPG???

This engine will NOT perform like the K-series. People are struggling to break 180whp with all the bolt-ons. You can gain 20whp with just a header on a K or adding a 3" exhaust.. not the same with the FA20.

My recipe for 200whp on the FA20(without internals):
- Custom intake manifold w/larger throttle body and possibly a spacer if it helps
- Custom intake tuned while on the dyno with a velocity stack (haven't seen anyone incorporate this on this site yet)
- Header w/matching complete exhaust minus the Cat's.. 3" ID piping
- Lightweight pulley
- CF or Alum. driveshaft whichever is lightest
- Motul or Amsoil synthetic oil swap (engine, trans, diff)
- Aftermarket ECU or some form piggy back that allows full control over the fuel tables and tuning capability
- Oil catch can setup (been shown to free up power) or if you really are baller go ahead and get a dry-sump setup. This will forsure gain HP but will cost about as much as a replacement longblock .. NA is not for the weak of wallet lol

I could go on but this should get you as close to 200whp as possible without the addition of internals or headwork.

Still don't see worlds apart. Yes, the K series does maker more power ( never said it didn't) and quite aware of their potential. Intake tune and full exhaust on our cars are seening 180-190whp. We really haven't found a legit header yet IMO. Once they change out the intake manifold and cams, then its a different story. But we have yet to see the same mods on the FA20 so far...

Most of our cars with i/e/tune seem to be in the 170-180 range from what I've seen. I'm not very optimistic that headers will make any power to be honest. Maybe on their own they will. But added to a car with a tune and exhaust I'm not sure there is anything there. I think we are limited by the VE of the motor. I mean, the stock cam is what 250 duration? No idea on lift. It really seems to choke after 6500-7000rpm. I'd love to be proven wrong though.
