Had no idea you let TTP touch your car... IMHO not the wisest choice, especially after I pulled the rom off a buddies car with a twin scroll 35R, it was running 18* of timing at redline on 93... made me sick to my stomach, needless to say the compression test showed cyl 1 to read way low...

 

Sorry to hear about your problems. Car was making good power before the boost spike issues. If that's our engine the piston/wall clearance was certainly not too tight.

 

Stock Evo X run 25-26* timing redline at fyi. Depending on the boost level there is 18* timing in all Evo 8-9 maps, including stock maps. The car you are talking about is my friend Jason D's 04 RS from Jax and was built 4-5 years ago before tephramods V6, V7, speed density, map switching, ecu controlled boost even existed. It was a 20psi pumpgas car. I've rode in it. If its still running after 5 years of a big turbo, that says a lot even through probable dealer trade ins and other owners of the car.

Since localtoys73 ran without problems before changing his catch can and wastegate springs to a higher spring rate then took it to another shop to dyno and they accessed the ECU and boost, then started having problems after that it tells me all I need to know.

 

piston to wall clearance is over 10,000 is this normal? I am being told it will not last if we put it back together as is. Also the pistons are non coated where it clearly states coated pistons on the website.

I sure wish someone in this industry would just give me a straight answer not point fingers at the other guy and say its there fault.

 

catch can was never installed and wastegate spring was installed and ecu boost taken to 0. Please dont stick up because you are a fan boy of scott. over 6* timing at peak tq.

Also your buddy Scott at TTp has charged my credit card 2 weeks after getting my car back for fluids he said he forgot to charge in the first place I dont mind paying for stuff but I think you should atleast tell me your going to charge my account before you do so.

 

I aggree its all my fault for going to people you think you should trust. I didnt put this car together I am just posting what has been found since taking it back apart. I guess the blown headgasket was the best thing that could have happened now I can see what true workmanship went into to putting this car together. I didnt tune the car either but its now all my fault that is the way it is. Guess my laywer and the courts will have to decide whos at fault it is in the end.

 

 

800 miles on the motor

 

How do you know boost was at 0%? Or at 80% wgdc if you were not the tuner? What makes you think you know what the peak timing number is? The car was a speed density car right? So where is 6* in the map? At what boost level? Do you know? Post the timing map and let us locate the timing number for the boost you were running on the original tune. It should be easy to spot. I suspect though that you have never even seen the map.

You are saying you got charged for services actually performed on your car that were accidently overlooked? So if Buschur shipped you that engine and forgot to charge your card until a week or two later, you believe you should get the engine for free?

I'm not a fanboy of anybody, but I am a fan of the truth. I have read in this thread you have blamed everyone from the tuner to the engine builder, machine shop, except for yourself when the fact is that you installed high pressure wastegate springs in your external wg and then proceeded to overboost your car with different tuner. Its not Buschurs fault and its not your original tuners fault as their tune was overwritten when you brought it somewhere else with your recently added high boost springs.

 

the facts will come out and be posted as long as this thread is left open.

No one has answered the questions is 10,000 to much for pistion to wall clearance? If I bought coated pistions why were the pistons not coated?

If the head was checked before removal how did 3 studs not register more then 80 ft tq?

Why was my card charged after the fact out of the blue without my notification.

Your right its all my fault.

mr truth guy please answer these questions.

 

25-26* is acceptable to me for a X at redline... If the car was tuned for 20psi then it might get up to 13-14* at redline but 18 is a bit high in my book... It would be probably be running flawlessly after 5 years of abuse if there hadn't been a ****load of timing thrown at it... enough to either crack the piston or fry the rings... especially if the car was only runnign 20 psi... You can nutswing all you want, but most people know exactly why TTP is no longer a vendor on the board...

 

Yeah .010 is too much, most forged pistons you can run up to about .006 (6 thousandths) and that should be max, maybe its been measured wrong? I'd double check. PM Me I dont want to clutter up the thread

 

Yes, the site does day coated pistons. I would like to show you something:

There is a picture of the actual 2.4 parts kit, the pistons are not coated. The 2.1/2.4 liter pistons are typically NOT coated.

Here is how the engine process works here. The block is taken to our machine shop with the piston for that block and it is then bored/honed.

.010 is the number you are looking for and that is on the high side of the clearance BUT you CAN NOT MEASURE CLEARANCES IN AN ENGINE THAT HAS ALREADY BEEN RUN/DAMAGED. You can plainly see that the bores have been damaged and I'd bet money that there are black vertical scratches on the piston skirts, so please post the pics of the piston skirts. Do you think that when an engine runs and you have issues like you have had that there is no wear? I think it's obvious there has to be right? Do you think the tolerances stay the same after that wear? No. Do you know what say .003-.004 thickness looks like? Do you realize that is a very small amount of wear and with the damage I can already see just on the cylinder walls to tell me the specs are out by about that much you and this machine shop you have the engine at aren't looking too, uh, with it? .010-.003/.004=.006-.007.

You guys who have these problems and decide to start talking lawyers always **** me off.

Here is how it works. IF you have a problem with OUR engine I want it sent back here so I can inspect it since I built it. I don't care what your brother, mother, cousin or John Force's personal mechanic tells you. I am the one who has to stand behind it and I am the one who needs to inspect it along with our machine shop. In this case, you handled it wrong and I have yet to see the engine and until this thread/today I didn't know anything about it.

Blown head gaskets are a cause of something. Loose head stud? Maybe. Detonation, more probable especially given the multiple tuners and the freak 46+ psi boost spike.

Post the pictures of the piston skirts.

 

Have to say one thing. You have to pay to play with these cars. Ive had many issues over time with my build but have learned very much. Im not going to chime in too much b/ theres way to many opinionated people on here that think they know everything and jump to conclusions.

Please dont stand up for a shop if you only have experience from your buddy, and not first hand! Charging someones credit card randomly afterwards without notifying the owner is uncalled for and bad business. IF you miss charged or forgot something you should notify the customer regardless to authorize payment.

Without 100% checking every possible aspect on the motor, tune and previous tune theirs many conclusions you can draw from this, sorry for your headache hope you get it all fixed

 

Anything can happen on a 700whp build and ANYONE who thinks they have a prayer in court when their modded car breaks is an idiot. If BR would even do anything about that motor I would **** myself. A 46PSI spike and detonation can destroy the best motor in the world in milliseconds.
