Daily driver reliability of FI frs??

[kmbkk]

OP, I have an FI FR-S with over 27K since the install (29K total). I've had zero issues with the kit. I've only tracked it once, and DD it ~70 miles. I'm not saying it's been perfect, but it's been very reliable.

Read all about it on the forums but most of the time, it was people issues. Running intakes & downpipes without a tune, not keeping track of oil burning issues, bouncing off the rev limiter, etc. I met a guy yesterday that hasn't had to change his STI motor, not even once! That's what I call a bulletproof motor!~ Save the anecdotes for the fox news crowd.

Yeah, the evo makes more power than the sti with less mods. Therefore the sti is shit. Got it.

Yeah, the tmic will heat soak if your doing back to back drag strip runs or on the dyno. For the track? Seriously? Can't even do mild track use with a TMIC? Where do you even get this horseshit?

Ringlands for those 25x's were a point of failure across the board.. I agree with you that it has been blown into a damn near witchhunt on iwsti and nastysoc,

The truth is the engine is very sensitive to detonation and yes, with those shitty ass intakes, crap tune, poor maintenance and subaru's emissions-centric tuning paradigm that caused such a horridly long closed-to-open loop transition, the EJ25x has received a bad rep as being an unreliable that I believe is unfounded. I took my shitty EJ205 to 200k, 100k of that pushing the limits of that TD04 and on E85 for around 1/4 of that time.. WITH trim problems trying to shadetree tune it myself w/ modified XPT maps on RR

I don't think they're unreliable if one keeps an eye on oil consumption and common sense not to starve the engine out on high G, high load turns....

The reality is that we're seeing failures because of people's lack of due dilligence, treating it as an American iron block pig when it's a dainty, quick little duckling. A nimble one, but not too strong

but I do think they're a very expensive to mod engine, with exponential increase in cost as one ratchets up the limit of the platform. It's the nature of the beast, they aren't well seen over 450-500whp reliably for less than a full build and you know that being an owner of one and seeing whats happening in the community

what kit and supporting mods do you run? do you have a build thread?

I also have 27k miles on my FRS, installed our turbo kit on it since 13k. No issues what so ever daily driving it (summer, fall, winter, spring). I do have our oil cooler kit and Mishimoto radiator just to be safe. However, I do not track the car or anything like that, but it is driven aggressively on the street. FI any car is a gamble no matter what, and you have to accept that risk. Especially your daily driver. It's been said a million times, if you can't afford the risk (blown engine etc) down the road, simply do not do it and enjoy the car the way it is. But it's a fun risk for sure. Keep the power at a reasonable level, good tune, keep an eye on everything, maintain it, and it should give you years of joy!

I'm running the Treadstone kit. They used my car to R&D the kit, and did the install. I did have the car re-tuned last fall by JAMESM to smooth it out some. As for supporting mods I'm running a full 3" TBE, not other power mods. I do have a Koyo radiator to install and I'm considering an oil cooler.

TLDR; TRD supercharger doesn't void warranty right? More power plus reliable enough Toyota isn't worried about replacing engines

Well correct me if I'm wrong but I was under the impression that if you got it installed thru the dealer it didn't void warranty. Ergo it must be sedate enough the dealer isn't worried about reliability.

IIRC, the TRD supercharger was a race only unit and you were forced to buy two at the kings ransom of 27k.

[Ashikabi]

Why 2?

[industrial]

So nobody other than professional race teams would buy it. It wasn't a consumer level TRD part. I believe they were 25k each, 50k total for the TRD FI system with a spare.
