Anyone with a V7 have significant piston slap on cold starts?

I'm hearing a faint knocking noise that's rather disconcerting (IE early stages of rod knock) when the motor is cold and I'm backing up or taking off in first, the noise goes away once the motor is completely warm and doesn't appear in any other gear or RPM range, just post clutch engagement + load.

My higher mileage EJ205 made a similar sound that Irvine Subaru informed me was piston slap, sound went away when the motor was warmed up as well.

Unfortunately I'm the only person in my immediate circle of friends that notices **** like this, two of whom have EJ207 motors.

And to top it off I've exceeded my 30 day "start up" warranty.

You're pushing the little 2 liter at 450. People have done 500 but i'm sure they didn't drive with that tune much, or if they did, it didn't last long.

v7 pistons are good, but you can still ringland them. At the amount of boost you need to do that you will probably be close to lifting the head on stock head bolts.

I've always said, if you're content with 400whp, the 2 liters are much nicer daily driving cars than the 2.5's. Buddy has a stock 206 (commonly known as the EJ20TT, incorrectly, but commonly none the less) at 325whp 310ftlbs on E85 with a vf39 and billet comp wheel. Fun, daily drive able, spins tires when it's under 40 degrees F. If you need 400+ to have fun, put a built IAG/Outfront 257 in the thing and call it a day. Have your heads chamber matched and you don't need special hybrid pistons or anything. Head studs, then you have a motor that will hold 700 and you're limited by injector and turbo only.

That's only ~5 grand though, so send it.

If you are talking flywheel power then that's achievable on the stock engine with the correct turbo and tune.

Can't hear a thing on that video. That engine is the quietest I have ever heard.
Did you have the sound on when you recorded

Haha yes, it's difficult to capture it with the iphone.

Going to keep enjoying it for the time being and if something develops down the line oh well, I've always wanted to tear one of these apart.

Fellow Ej207 owners! I require some quick assistance! My gray plug on my engine was damaged when the engine was pulled, I don't know the layout to repin the plug. Here's a picture of it.

I'm also located in Oregon and interested in buying a 3" JDM downpipe from someone/trade for my Cobb 3" USDM downpipe. Thanks all!
