It is the second OEM stock block that has been "blown up".
I actually purchased the first one from Fernandito and built it up.
The first only had two slightly bent rods and a squished oil squirter.
Sounds like this one launched at least one rod though the block.
Oddly enough my new (his old) block is sitting in the very same shop probably a few feet away awaiting install with an APS system into my G . Hmm.

So sorry to hear this. I also dont believe this was the Gredy kit per se. I have been calling the Greddy kit the "tuner twin" kit. It really is unsafe out of the box..even with stock boost and stock tune. Timing must be retarded...even with 93 octane fuel, and the shielded CAS is a very good precaution. I image with these precautions, at stock boost, we would rarely see a blow up.

Whenever a turbo kit is installed, it must be dyno adjusted, IMHO. Each car and ECU responds different to the base mapping..on all of the kits..not just the eManage kits.

And as mentioned, it is very possible that engine damage can occur over time....detonation that you cant hear....hammering of the main bearings...and then at a moments notice...even when cruising...boom.

I know it doesnt help solve your problems, but the reason more Greddy kits blow up, is because there are TONS of them on the road, and very few are fully tuned, and the preventive additions are usually not made. APS locks their system down, and does a better out of the box job with the fuel and tuning areas...hence...less blow ups.

Believe me, there are some APS blown-ups too...but Peter has brainwashed everyone into not posting about them....smoking turbos....blown rings...etc.....

I just wish more people would come forward, becuase it seems the only kit that gets a bashing these days is the Greddy kit. I ran mine for 15,000 at 8.5psi without even a hint of damage to the pistons, bearings, or anything else for that matter. Westpaks is running strong too. All comes down to thorough tuning, and taking the necessary precautions. Westpak's is MAP tuned as well, and he has the CAS shielded wire

WRT to the APS "smoking turbos" I have witnessed this and it was only a kinked oil return line. Others simply overfilled their oil level which slowed drain back into the pan an hence cause leakage past the Turbo bearing seals. There were no mechanical defects with the Turbos for this "issue" to my knowledge.

Charles posted recently about smoking turbos..and this was after reducing the oil level (down to 5 qts, even though the APS oil pan claims to add 1 qt additional capacity), checking the lines, and even tearing down the engine to determine if the rings were improperly seated. He can provide more details if he chooses to.

I'm really curious about this; I noticed quite a bit of smoke coming out of the exhaust when I first drove the car. So Phunk only puts in 5 quarts total, allowing for the oil filter? I spoke with Tuan and he puts 6 quarts in all of his installs. Actually he said he used to put in 7 quarts!

You have been on this board for a long time and i respect your contribution but I hope you have evidence to back that claim. If i had an aps kit and it blew, i would be here with pics out the @$$.

Im really sorry to hear of your misfortunes, but like evrybody said, the stock Greddy tune is def not safe. You should have done a little more homework and you could have seen numerous examples of what has happened to you. I cant believe some guys have $$$$ for a Greddy kit and install, but wont spend a few hundred more to control timing and tune it, or just get the Technosquare reflash, and a CAS wire. Sorry you've been bitten twice by these TT, but I dont believe it to be at fault-although I do agree with you that Greddy should include timing control in the kit. At the end of the day I think a $600 reflash and a $70 CAS wire would have saved you a lot of hassles and money. Alberto <-----dont mean to come off like a d!ck just stating my opinion, good luck in the future.

IMO anyone running the greddy on stock boost should stick to the Technosquare greddy tt flash. To my knowledge no one who has gone this route has had any problems.

the only reason i went as low as to only put 5 quarts in is because that is what was personally directed to me by a representative of APS. I run 5 quarts in cars with stock oil pans.

I don't know enough about FI. But, after 3 years, I'm going to say, screw this kit, get APS if you're going to go forced induction.

Marluci,

How are you boosting 18-20psi with your APS TT? No one else has been able to get past 12psi.

Fernando,

Man I'm sorry that happened. What a sh1tty way to run into you again. Im just glad I was there to help you out. That Greddy has claimed more engines than anything. I just wish they could of provided a lil more help or time to test that kit. I know Tuning was not your issue. I wonder if our recent temp change had anything to do with it. I bet the settings on Greddy or any TT are sensitive with our engines. I better get mine in for a recheck. After I stopped I was worried. I didn't get on mine to much that whole day.

sorry to hear of your troubles-

hopefully you can re-coop some of the rebuild costs with the sale of your TT kit...

That's what we do with these kits now. We do have a few running with e-manage and no problems, go figure.

Crankshaft and camshaft angle sensor wire. The crank sensor enables the ECU to determine at which angle the crankshaft is at, and at what speed. Using these inputs, the ECU is then able to look at RPM, throttle demand, water temperature and air temperature to calculate exactly what the correct advance is. It does this by looking at a three dimensional 'map', which plots advance against throttle load and RPM. Additional correction factors for temperature and cold start requirements are then superimposed on these values.

Did you retune the ones with the emanage or did you leave it on the out of the box setting.

BTW I only have 14k on the OEM block.
Thanks Grp0 but rob has already found me a new block. This is my only car so timingis critical. That would have been sweet if u could have sold me ur engine .
