I know how you feel - been there
I'm a proud owner of a em2 since 4 month now and found prety mutch same things as you.

i/h/e - I never get any proof of result of this. Some people told they had feel a difference but it did not give really give a good power gain

turbo - few kit exist to bold of a d17, from what I understand you can run up to 8 psi with out internal mod but all turbo is closely link with the ECU tuning.


I'm noob so don't quote me on this


is some people with N/A D17 real life experience can share there knowledge?

speedfoos - search his threads

lurk around the site a bit and you will see that its not how much psi you can safely push, but how much horsepower you can safely push. Even then the better the tune, the more power your stock block can handle.

There will be a general number, but unfortunately there aren't an over abundance of 7th gen owners on this forum.

hope this helps -

no such thing of how much boost can you handle a real big part is the size of the turbo how much CFM can i flow like 10psi on a 16g compared to a 10psi on a gt35r is a big ass difference

Exactly. You'd be fine at 250 with stock internals, assuming you run kpro and have a decent tune. I'd say 300 would be ok. You could possibly get by with more but much over 300 and I'd say it's about time to build.

IDK, Have you seen the spindly rods that come with the D17?

Like Andy mentioned, its all in the engine management and the tune. Rods are good insurance if something goes south, but bad detonation on a F/I rod is just as bad as, well, bad detonation on a stock rod. If you're doing something with the engine that is going to bend/break a stock rod, then stouter F/I rods are just going to delay the inevitable.

But yeah, I would say 250-300 if you're running a standalone and pay a reliable tuner to dial it in.

On a piggyback, I wouldn't run more than 200-225 unless you plan on rebuilding.

thanks for everyone that posted, I'm trying to get around 200hp. now with that said as long as I got a good tune (some shops in mind? like is the dealer good?) and a new ecu (any recommended?) 200hp isn't bad on a non-built d17a2?

Yeah, i've broken stuff on mine with stock internals at 260whp, but I don't think built internals would have prevented what broke (shredded main bearing, not spun thank god).

Oklahoma tuners? Got me man. You can't take you car to a dealer to get tuned.

200 peak HP should be good. :TU:

Good Luck.
thank you!
i'm goin to start saving up for a kit asap after i get my rota d2's and fog lights. ;D

i think i'm going to piece together my own kit versus buying a 2k kit and only boosting at 8-10psi kind of a waste you know

I am on stock bottom end pushing 265 whp at the moment. That's at 8 psi. I dropped valves and destroyed two pistons a month ago. Block is being disasembled and rebuilt as we speak.

The only reason I'm only running 8 psi is because the tune was on 8.8:1 c/r pistons and I'm now at 9.9:1 and don't want to destroy it by pushing too much on an untuned bottom end.

Previously, I ran 15 psi with a different turbo (right at 300 whp) for over 9 months. When I pulled the motor, the entire bottom end was pristine from the piston dishes to the bearings.
