What causes that torque dip these cars have? Is it something all the cars that use that engine have?

In that dip is the only time real-world emissions will match stated emissions amounts anyway. The only thing a basic tune does is eliminate that dip so the power curve is actually a curve (like you would expect for an engine). The dip only exists at all because that is the specific RPM range that the emissions testing uses.

Emissions tests follow set test cycles but you don't really get to higher RPM during them. They could have gotten things to work without the bump and passed emissions I'd think, every other manufacturer is able to.  IMO it's a lovely job calibrating but there must have been a reason to do so that made it the better of the two trade offs. I wonder if it's something to do with their wonky PFI and DI injectors but I thought they only used PFI for cold starting and then it was DI the whole way?

Yep, it must be the transition of the injectors (both to DI only) is my guess, then. Seems dumb since you can get away with one or the other just fine and still meet emissions.

stevobob posted:Isn't this slightly better though, in that you get the benefits of direct injection without the coking of the valves/intake from EGR crud? Slight correction, but it's probably coking from PCV. I have no idea honestly if this engine has EGR, it just seems less common these days. In theory, yes. Having port fuel injectors should help the valves stay cleaner. It's a controls headache though, controlling two sets of injectors simultaneously ramping one down and one up and having it be smooth during the transition at all loads. Seems like more trouble than it's worth. Eventually we're going to hit the cap of how much fuel can be injected directly (more likely limited by the pressure from the HPFP) into the cylinders for higher horsepower stuff, so split systems like this will probably become more common. My derail and theory posting ends here.

So this has showed up on CL and is pretty near me: http://sfbay.craigslist.org/sfc/cto/5317009327.html the seller posted:Amazing car set up how it should have rolled out of the factory. Adult owned. Proper break-in and always let it completely warm up before getting into boost or rpms. On the one hand, $28k seems a little rich for a BRZ with a voided (i assume) warranty. On the other, I can't really say that there's any aftermarket stuff here that I don't want. I don't know anything about the coilovers, but I think they might be made by KW for Racecomp? Car seems a bit too low, but hopefully the coilovers can get to a reasonable height. Well, and that black fender trim piece looks a little stupid. So uh, bad idea or worst idea?

Problem is his base $26k is bs considering a brand new limited 2015 is that much for invoice (easily achieved on a brz these days as they don't move off the lot since its same poo poo that was released in 2012). A comparable used brz will get like $21 or 22k

Paraphrased responses from the owner: - selling because kids - original fender trim pieces were stolen (is that a thing that happens to you guys)? - <3k miles on springs, <2k miles on JSRC - did the s/c install himself - a shop did suspension and alignment

The suspension is good stuff. Basically a KW V3, so good quality double adjustable shock, but with slightly different spring rates and valving. KWs come with an overly soft rear spring IMO, RCE fixes that. Rides well, will go a long time between services, can be rebuilt and re-valved by KW, RCE in the US with a pretty short turnaround. And it will go up to stock height or maybe a little more if you really crank up the spring perches. Jackson racing guys do good work as well. If he's been driving it for 2k miles without it blowing up or lighting on fire it'll probably be ok. jamal fucked around with this message at 22:53 on Nov 28, 2015 |

Or he thinks (apparently rightly) there's people who'd be willing to pay extra for mods in this market? Does the JRSC come with an intercooler? When I had my STV Focus, the JRSC kit didn't have an intercooler, while the next step up did.

Yeah, I think there is a (small) market of people who might even pay asking price for a car like this, but apparently its been for sale for 12 days. I sold a turbo 95 Miata for $8k, so people pay for modzzzz. I don't think home-install s/c necessarily means run away, it just becomes a wildcard. I figure a PPI at a good race shop would go a long way. From what I've heard the JRSC has been a pretty trouble free setup. Anyway, probably won't jump on this, but it makes for interesting discussion anyway.

Put another way, if you're going to buy a used $28k car with no warranty and questionable future reliability you can do a gently caress of a lot better than a BRZ.

I going to agree with this guy, 28k gets you a new WRX or BRZ or any number of used sports cars with more power: STI, S2000, 350z/370z, insert your favorite v8 muscle car here. I only really consider that BRZ if I had a nice garage full of tools to work on it.

Yea sorry it's not dollars per horsepower, it's dollars for the complete package. The BRZ is an interesting new car, being the cheapest sports car on the market, but outside of filling a niche it's still just a shitbox Subaru. If you aren't getting a warranty or even the expected reliability of an unmolested new car why would you ever want one over a used Cayman for example? Do what makes you happy, nobody cares, just be honest with yourself about your decisions rather than trying to rationalize.

Get an e46 M3 for less money and faster real-world driving with more power and practicality, more reliability, cheaper serviceability and 99.997% less chance of shorting out the front control module (and subsequent random cascading module failures) via the unforeseen act of detailing the loving car. Even disregarding the IMS ticking time bomb, the first gen Caymans are hot garbage. If you ever have to transport a cooler or suitcases or anything other than the regulation Porsche golf bags you will hate life. If this is a track toy, disregard. Get a Miata.
