What my conclusion on that transmission was 8k clutch drop and the crappy xtd pressure plate just blew itself apart. None of the bolts were loose all of them were sheared off on the flywheel along with the dowl pins. From the story's I heard there was a volkswagon trying to race him.

I actually am the one in possesion of this transmission, those pics were actually taken at my shop lol. Gear box is still good, no shaft play at all.

+1 ,could also have had a hair line fracture in the flywheel and it got progressively worse until it let go

The flywheel was fine everyone, I removed the blown trans and put the new one in this car. Besides all the sheared off bolts and dowl pins there was no damage to it. It was not loose it was torqued to spec when the clutch was installed. It was still tight even after the pressure plate exploded.

Oh and btw he bought another XTD clutch

So what failed? the pressure plate bolts not being tight? Or the plate came apart itself internally?

The pressure plate itself. He said there was a volkswagon trying to race him. We are guessing he reved it up real high and just dropped it.

I guess some people just need to catch on fire or cut their feet off before manning up to buy a real clutch...

Where those fingers that are providing 2400lbs of force release causing a similar assplosion as C4?
Did i win?

And i thought he wasn't *** hat driving? 8k RPM isn't a walk in the mall.

He was definitly trying to mess with the VW whether he admits it anymore or not. He also told the cop that he had an "illegal skyline motor". I posted other pictures of this explosion while it was still in his car awhile ago. ill see if I can find them.

First of all it was my car and i was not trying to race anything. Second no one mentioned the ongoing problems I had with the transmission.. I am really upset that someone not mentioning any names would talk crap about me without the you wan't the real facts.. I had 4 eye witnesses at the scene and my finance in the car. Now if everyone says i wasn't screwing around and the cops wrote it up as an accident, believe what you want you want to start talking bad about me why don't I just mention names of who built my car and all the problems that I faced with the car NOT cool

So in your "expert" opinion it was the XTD clutch assembly that was faulty...the pressure plate especially. But when you installed a new transmission you went ahead and used the same type of part that you already found to be faulty? In fact faulty to the point where another person was injured...

I'm just clarifying things here a bit.

Easy bro...we'll get to the bottom of this. Can you tell me the date that this happened? What were the issue with the transmission? Was it hard to get in gear?

You might want to edit that post a bit to...lol.

Did you not say that your car reved up "by itself". Secondly your oil leak was from your leaking power steering rack. 3rdly I was not there when the motor was installed but I do know andrew knows what he is doing, and there is no doubt in my mind that it was installed correctly. I am not talking trash on you I am just saying what happened from what you told me(there was a loud VW your car reved by itself). I have no problem with you, i just think that this situation is pretty funny now that it is done and over with.

I mean its hard to believe a pressure plate would explode at low rpms, yes possible but not very likely. Chances of getting struck by lightning are probably higher.

I installed what was supplied to me. Believe me I would never recommend putting in a ebay pos clutch. And im pretty sure I said not to use a XTD again. But that was not up to me.

I really hope he didn't mention anything about the "JDM TYTE DEIFT SPEC SKYLINE MOTOR" to the cops as mentioned. That's all I need when I try and take my drivetrain back is cops inspecting for that kinda stuff because they heard those "Skyline engines" like to blow up on the street.

ok i didnt mention anything to the cop till he poped the hood and saw a 6 cylinder that said rb20 on the valve cover and a fm, he asked this is not an american engine what is it. I told him what it was becuase he alredy knew, the cop was into imports. As far as being told not to use an XTD clutch that is bogus. I was not awre they are not good, why would the guy building my car recommend and tell me its a great stage 3 clutch? And again I had my fiance in the car, 4 witnesses at the scence plus the two people in the car that was hit by my bellhousing. All of them testifed to the fact I was doing less than 35 mph and the VW was at least a 1/4 mile ahead of me. Why would I even waste my time with a Golf? And why is there huge stains in the garage and driveway, that currently are both red and brown? Why would someone build a car for me if they knew the Rack was leaking, I was not informed of this till 3 1/2 months after the car was built. I would of bought a new steering rack b4 they dropped the motor in. Last Steve how many times did u tell me u wouldnt do business with the person who built my car, you said hes not reliable, and not good with customer service, so dont go there saying u trust him!

I know for a fact I told you and I told andrew XTD clutchs suck. Why you got another one was between you and him. Andrew checked your trans fluid 2 times after the swap was done and it was still full. Maybe you werent beating it when the trans blew but minutes before that could be a differnt story. And as far as the rack, im pretty sure no one knew it was leaking because the car had no motor in it when you bought it, and fluids were drained.

The day you and andy got into a fight, i did say i was not impressed with his customer service, BUT then he did install a trans FOR FREE.

I don't want this to turn into an online pissing match... though it seems that's inevitable at this point.

The purpose of this thread was to ask the experts here online what the cause was for this damage. Dan wanted to put the question out there without pointing any fingers or making any accusations of wrong-doing. That's why he asked me to post the thread.

What bothers me about the whole thing after reading thus far is:Why didn't Dan know what the cause of the problem was? Why did his trusted mechanic not explain to him that the clutch pressure plate let go and smashed up the bellhousing? Had he known that it was a bad clutch, he probably would have taken a different course of action. First off, I bet he wouldn't have purchased another one. Second, I bet he could have gone back after XTD for a refund. But obviously he was never told what the issue was. That bothers me a lot!! How can a mechanic who's charging for labor not explain to the paying customer what the damage was caused by and why this situation is happening?

I'm not calling out Nissans13240sx as a poor mechanic. I don't know enough about this situation because i'm only hearing things from other people. But, I think it's safe to say that you don't communicate very well with your customers. From what little I understand about the course of events, you should have told him what the cause of damage was before moving forward with a second one.

Also... what was the deal with the speed sensor not being installed properly and dropping all the trans fluid on the parking lot at his work?

Who the heck is Andrew? Is Nissans13240sx the mechanic or is someone else?

Andrew is the one who built the car. Nissans13240sx is Steve who helped andrew install the transmisson after it exploded. Like I said to Eikon I didnt want this to get ugly, I just wanted to know the cause. If I would have done an 8k clutch drop, I would of known the cause. I am not that stupid. I was never really told what caused this situation, so I looked for alternative help. As far as the speedo sensor, it was apparently caused by wires that got damaged in the explosin. The fluid I saw supposedly turned out to be massive amounts of Streeing fluid leaking out running down the bottom of the car and coming out near (very near) were the speedo sensor sits. I wanted to move on about this and just try to find a cause and this had to happen.

I know for a fact I have told dan from the begining that XTD clutches suck. I am pretty sure we told him it was the pressure plate when he was at my shop taking the pictures of it. I did say go back to XTD, but the rest is out of my hands.

There was no problem with the speed sensor, except for one of the wires being broken from the bellhousing hitting it. The only fluid he is leaking is P/S fluid.

Again, Steve ur not understanding. I did not play around with the VW Golf b4 hand, I was on a single lane road in Allentown (a CITY). Tell me then why did it buck between shifts, and i had so much problems getting the car into gear, and not to mention trying to get it in reverse was a pain at times. I'm not saying Andy is a bad mechanic, he knows RB's very well. Also he replaced the trans because i bought a new one and he agreeded to do the install free, and buy me a new clutch. Reasoning behind my frustration is it took him an extra month and half to build the car and was way past the deadline. Plus I could of gotten at the time from two different companies a RB complete swap for $1100 shiped and a year warranty and instead I bought the swap through Andy's friend for $1500 with no warranty when in fact I was told it would have one. I had many many problems with this car, and what was I told? "You shouldnt have bought an RB20 if you were not a mechanic, that was stupid!" I had the car for 3 months when this happend, thats just a little redicoulis. And Steve I have Debbie to testify to the fact you have said way more about Andy than ur owning up to. SO again please dont make this a battle back and forth. I just wanted to get to the bottom of this. And i feel you had no right to pst up a thread in the SR20 forum when you would know i wouldnt look in there about what happen to me and my car. NOT COOL!
