My head is stock. Pistons and rods? There's Belfab Racing, Spool and Maxspeeding. For pistons, Arias makes some. I have a JGS turbo manifold. I'll probably sell it next month. I'm getting one custom made. Well, tomorrow I'm taking this bad boy to the dyno. Chances of catastrophic engine failure: HIGH.

Dude, if you're gonna destroy it...might as well ship the engine to me on the cheap.

Alright, went to the dyno yesterday. We decided to eliminate the chance of breaking the engine by the fault of tuning and agreed to go very safe with pretty retarded timing and the AFR on 10.3. Even though doing it this way robs a lot of power that could be made, we still got 187.70 WHP at 9.94 PSI on the wastegate spring. It would've been over 200 WHP if the car had a manual tranny. With forged pistons and rods, it would've been safer to lean it up a bit and give it more timing advance to get considerably more power. So knowing that is good enough for me. Oh, the torque was always higher than the horsepower, which made me smile. I don't have the runfiles and the print-out doesn't have the torque, so that's why I didn't give you numbers.

Now to the bad news. Due to a faulty manual boost controller, on the last pass, not even going WOT, it overboosted to 18.1 PSI out of nowhere and I let off the throttle, but it was too late. We heard a sharp cracking sound and a bit of smoke started coming out of where the PCV valve goes. It put down 222.53 WHP. AFR was still at a pig rich 10.3 and timing was safe according to the expensive digital timing gun we used, so I concluded that these replacement pistons are garbage. Car still runs good like nothing happened other that sounding a bit like it's cammed-out, but it spits oil out of the PCV outlet under boost. I'm sure the same piston broke on the same spot like last time. The ringlands are weak. I'm not going to waste any more money or time on stock internals because I think this was enough to know the limits of the pistons, so this is the end of my journey here with them and with piggybacks. Rods are fine and dandy so contrary to popular belief, they're stronger than people thought and shouldn't be the first concern. Pistons are the weak link. The next person that ever posts that the 7A-FE's rods are very weak because of how skinny they are will be flamed with no mercy.

Next week I'll be shopping for forged internals and once I get time, I will get them installed and then I'll get to installing the standalone EMS to be able to play with the tuning the way God intends. Then we'll go to the second stage of proving the 7A-FE and its slouchness.

Wait...I thought you had done work on the internals, but you're only running aftermarket pistons?

And 187 WHP is AWESOME. I had no idea it would be so high. What do you think 8 should produce?

no his whole block and head is STOCK so those numbers are pretty Amazing <3

motivating me to boost my 7a...YOUR AMAZING MAN KEEP IT UP!

do it warrior

i know i should right? man itll be so awesome...since im auto ill have full boost...but i wish i had the money and the actual skill to do it myself AND another car lol my celi is my only car...unless i buy another celi and then boost my current one...who knows maybe im that crazy to actually do that lol but it wouldnt make sense cuz the money id waist on the new celi couldve been used for the boost...sigh decisions decisions

civic radiator?

If it's your only car, don't boost it. You'll always end up breaking something. Anyway, my car is hurt. The temperature guauge wasn't working, and the radiator fan's positive cable unsoldered from inside, so the car overheated and it's messed up now. I was going to an appointment at the VA hospital and BOOM...coolant and steam everywhere. I left it in a parking lot and went to my appointment, then came back an hour later and called a tow truck. $100 to tow it back home. I think the head warped, because it won't even idle, and it misfires like crazy. I asked for it. Should've gotten the gauge working and a better fan. It was a cheap $35 fan from Pep Boys. Another lesson on why not to cheap out on a car.

Today I ordered Spool forged rods from Australia and tomorrow I'll talk to my tuner to see what we're going to do piston-wise in terms of compression, etc. I'll give CP a call to see what they can do for me. I dig their pistons. A guy from the local forums wants my e-Manage so I'll let it go for $250 with everything.

oobe,you have to much money..and ur dumping a lot into the 7ate..its wonderful...

sounds like someone i no, go all out or dont go at all

damn sucks about the overheating. Cant wait to see the rods

I wish you hadn't said that.

Ferdi, it's your only car. Boost it! Lol.

Those are some pretty amazing numbers you put down, OOBE.

well mine was and is my only car...and i will do more modding tomorrow.

^ I'll be asking you a lot of questions in the future, my man.

Thanks, man. To me they're not amazing, though. What's coming soon WILL be amazing, at least for us with 7A-FEs.

Im excited...haha

LOL...if I had too much money, I would've finished the car already. But yeah, it's wonderful.

Hey guys, lookie what OOBE just got in the mail...straight from Aussie Land.


Hmmm, what is that?
