Question for the Turbo community.

[NickFRS]

I keep seeing all these stock N/a cars blowing up n what not or getting CEL. Has any Turbo FRS popped yet? Or get any CEL?

Questions to be answered,
When does the stock clutch start to slip, __________________.
When does the rear diff become overwhelmed by power, __________________.
When does the M/T become overwhelmed by power, __________________.
When does the A/T become overwhelmed by power, __________________.

Which builds have blew the engine or major component and at what power/boost.

Most miles on turbo with stock internals.
1. AVO Kit 4k miles and holding strong. (HP/TQ/PSI unknown atm) https://www.facebook.com/media/set/?...9614524&type=1

Most miles on supercharger with stock internals.

blown up? where?
where's the link?
people are running 500whp with a turbo on a stock engine and nothing has gone rong appart from the obvious clutch not holding.

Yeah, if you've got some links to these blown motors I'd be interested in reading them.

The turbo'd brz and fr-s will have some serious issues down the road from what I've been told and researched. Damage from high temperatures staying high for too long.

There is one turbo kit I would consider but this car wasn't designed for turbo.

It's (BRZ) made for linear power delivery peaking near/at redline without sacrificing the car's beautiful balance and precision.

All of that is lost. There is a Turbo BRZ you can buy without voiding the warranty. It's called a WRX.

Maybe I'll catch alot of hate for this post but I honestly don't give a fuck what people think. Everyone is so closed-minded on this, they read only what they want to justify their decisions, and when someone shares their opinion people take it like it's a lethal threat to their well-being. Fantasies being shattered with some factual information.

I was one of the guys that really wanted turbo. I talked to some very knowledgable and experienced people on this matter. I then did my own research.

Thanks

I honestly don't understand what people mean by this statement. It's not that I can't comprehend it, it's that I don't see it. I've driven 'precise' cars (Elise / Exige). I've driven 'balanced' cars (S2000). This car has wagon wheels for tires to make up for a lack of power, and with its massive torque dip, I don't know if I'd even consider the power linear. Proper tires and a few more ponies are what the car begs for, to be honest. Off the show room floor it's not a balanced car in my opinion. Sure it's a great car, but I wouldn't call it balanced.

It's almost as if they engineered a beautiful chassis and then the bean counters got a hold of it with the engine. Once that was finished, the marketing guys got their hands on it to make it appeal to the 'JDM drift yo' crowd and on went the tires.

I only know of one throwing a rod so far

Nobody knows that, they simply make assumptions of that. The only way anybody would actually know that is if they actually witnessed it happening. Which, to date, it hasn't.

BTW, even Subaru thinks it's possible to turbocharge a FA series motor:
http://en.wikipedia.org/wiki/List_of...baru_FA_engine

For further research, check out the turbo forums, such as NASIOC. A bit of a mess there, but one thing you'd bring out of it is the same thing anybody experienced in turbocharged motors would tell you - what destroys turbocharged motors isn't "high heat", it's detonation. Broken ringlands, broken rods, etc. Which is only peripherally related to heat.

While boost can contribute to detonation, that's method independent. Raising pressure in the cylinder will do the same thing no matter how it's done - whether from a turbocharger, a supercharger, or simply raising compression ratio. In all cases, the real issue is the engine running lean, and that's down to tuning. Which is why I've got an Outback 2.5i with 200k on the clock, a turbo kit, and compression of 200+ on all cylinders.

Boost doesn't kill motors, bad tuning does.

There has been a report of an ft86 down here in australia where it's block had a size of a tennis ball in it! I'll try find a link for you

edit: can't seem to find a darn link.. but I think it was running 10psi and the turbo was from a garage called Castle Hill.

No one will take you seriously. You provide no facts, numbers or math. You don't even have anecdotal evidence. Then you talk a lot about research. What research? This car has been out for 6 months? Are you kidding me?

Many performance cars that have excelent balance and handling have turbos. What makes you think this car turns into a hummer when you turbo it? Where are the facts to back up your statements?

Virtually everything you said here is complete bullshit. Furthermore, people can mod their cars anyway they want, and be happy.

Everyone is so closed-minded on this

Especially you. Nobody should give a shit if you think the car deserves a turbo or not, as long as it makes them happy.

Everyone is so afraid of "throttle response" degradation with a turbo. But a GT28 can be extremely responsive, especially with 12.5:1 compression. No torque dip, and a 100whp increase over stock. If you wanted perfect throttle response, E-throttle isn't the way to do it. There is no more delay on newer turbos than a typical e-throttle setup if it is sized properly for response.

I've tracked t28-powered cars before and the response is fantastic! There is only a mild drop in response below the boost threshold. They wouldn't be putting turbos on drift cars if their response sucked. It has to be properly setup.

and @ freeman re read my post. I SAID N/A MOTORS BLOWING AND ASKING IF ANY TURBO ENGINES HAVE BLOWN YET! BLOWN = POPPED. Now back on topic

[NickFRS]

Also I come from the turbo world of subaru. I had a 2011 STi that was modded and I had a 2002 WRX that made 350WHP and now my dad owns it with 80k in mods and is well over 400HP and STi swapped. Everyone knows the smaller the turbo the earlier it spools. My VF48 on my 2011 STi made max torque at 3500 RPMS! My dads 2002 WRX makes max torque near 4.5k with a 35x. Smaller the turbo the less lag and less power. Bigger the turbo means more lag and more power. Everyone should know this. Sure supporting mods have key factors also but it's common physics and chemistry with a bit of witchcraft.

My main question is has anyone blown up a FRS/BRZ/86 yet thats turbod? Also how many miles do these people have on their kits?

Personally i'm thinking about super charging my car or getting a VF48 STi turbo and making that work. I'm not into big power just want 100hp+ at the wheels. I would be fine with 5-10PSI. This whole question is mainly around reliability. So does anyone know of a pop'd twin? If so how much boost/HP was being produced and what set up was it? If we know this maybe we can narrow down a safe build or a more reliable build or maybe figure out a mid ranged build this engine can handle? Also has anyone smoked their stock clutches? wonder what they can handle.... or has anyone blew their diff yet? or tranny? Lets figure this out and be aware of what our cars can handle.

Every car has it's limits. Lets figure this out as a community.

No name calling or mean gestures please lets keep this civilized.
