LOL, why not share? At this point who would care to keep it a secret?

The reality is modified cars blow up all the time. The difficult thing in suing them is it will be hard to prove negligence. It's not like dropping your car off at a shop having some written up repair done. Most tuner shops will never, ever, cover a blown engine. I have even seen instances where they built the motor, it blew up, and they still didn't do anything. There are no warranties...


What is the small claims limit in FL? The time and cost of taking them to court would be much less with small claims. Otherwise its likely not going to be worth it.

If we wanted to start a vote, I'm going with: Missed a shift

Post the logs.

Did 300 blow another engine? Dude you're going to be into that car far more than a Cayman S would've cost if so.

@Mujen84 I don't think there is a way you win with this situation. You may get your car fixed for free about a year from now if you indeed win a lawsuit. You may spend more on the attorney than a new/used engine would cost and lose the lawsuit. Attorney fee of $100/hr would eat up $3500 before you even saw a courtroom.
If it were me I'd go get my car and have it fixed elsewhere then sue the guy for the cost of the repair. Just document everything and good luck with your dilemma.

No.

Unless the car is knocking really badly from poor tuning it's not likely the cause bearing failure.You should hear this type of detonation easily. On teardown it would be evident on the plugs and on the pistons in the cylinders where the rod is not broken. If it was caused by a lean condition as they say the result is normally a melted piston/plug, not a bearing failure. That being said, the tsb for the DI fuel pump is for noise, not a complete failure. The logs will shed more light on what actually happened.

I have some connections, I spoke to a lawyer, we discussed my options & did some hypothetical scenarios. I've spoken to a few ppl & taken into consideration all the information everyone has said in this post (which I rly appreciate the input as you guys are all way more knowledgable than I am currently). I've decided to bite the bullet & buy a 3k mile FA20 for $2400 & he said it'll be rdy in 1 wk fully tuned w/ the kit back on and oil cooler mounted to the side (cuz I dnt like it in the front, I rather get an aftermarket brake duct. I rly like the evasive motorsport FRS that car is so sexy & they did a custom duct for oil cooler).

What I've learnt from this post is I need to have better text bk & hands on knowledge of cars. If you're getting into aftermarket parts & racing (I've tracked the car much earlier on) is that you need knowledge & working on the car myself is my ultimate goal. Also there are high risks & high rewards. But I am not going to give up my dream to enjoy racing now that I finally have that option in my life - this is what it means to be a racer/driver

Thank you everyone for your input! Sorry if I disappointed some of you by not being more aggressive & I hope this goes well from here on. And for those who have been/will be in my situation or similar I feel your pain, our cars are more than just a means of transport but a bond.

I'm spending my Sunday just researching car info to better educate myself mechanically. I still have 1 question lingering in my head that I haven't gotten any direct answers on as yet... What exactly happens when the mechanical fuel pump suddenly stops in a turbo car? Does the car simply run lean & blow, does it shut off and go into cruising? I want to better understand what exactly happened to my car for myself & perhaps prevent this in future or determine the validity of this explanation I've been given.

Btw I found this lovely BRZ article on breaking down the car: http://www.tune86.com/ft-86-news/210...ed-jeff-perrin

Before this incident I didnt even know much about fuel pumps, now I need to learn evrything about them lol.

It is very unlikely that the mechanical pump on these motors can fail. Your intank pump has a much higher chance of failing than the mechanical one.

How would I verify this? I'm going by the shop tomorrow where my car has been on a flat bed trailer for a few days now. But let's give the benefit of the doubt.... IF the pump died, what exactly happens? According to what he told me, it just happened in a second. As a non-expert to hear this and then go drive again with turbo I'm concerned & very curious. Because theoretically if this is indeed true, could happen again randomly?

The DI pump operates like a valve, It rides on the lobe of the camshaft and when the cam rotates, it pushes on the piston that in turn compresses the fuel. The fuel is compressed upwards to nearly 3000psi.

I don't know how you can test one of those to determine that it is bad but the chances of it being bad is very very slim.

The DI pump relies on the Low pressure pump to feed it. If the low pressure pump is bad ,it will make the DI pump look as though it is bad because it lacks the supply of fuel to compress.

Firstly I just want to say I appreciate you giving me your expert advice I have been very interested in your R&D on the frs/brz. In fact I called the shop a while back to talk about turboing my car but u guys are kinda far & I dnt trust myself to install a kit lol
Okay so... He is basing this "pump failure" off engine logs which I am not well versed in... And this fuel pump recall paperwork he gave me which a friend pointed out that it states: "this result is non-detrimental to the fuel system or engine." So turbo or no turbo, IF the fuel pump did stop... Would the car run lean and explode? If the electric pump stopped would t explode? I'm researching and I've only seen 1 post discuss possible detonation but majority state the car just stops going. If the failing fuel pump doesn't cause detonation then we clearly have a false statement.

P.S. I had asked him if I was driving around and this happened non turbo (I've had the car for 20.5k miles) would this happen? He said because of turbo it's far more detrimental effect.
