It uses the stock exhaust manifold and meets California emissions requirements. Thoughts?

There are plenty of turbo kits that utilize the stock manifolds and make a shit-ton of power.
I see no issue here

I will give them props for a rather elegant solution to using the stock manifold and exhaust, but everything else about that screams poorly engineered. Sure it makes power over NA, but you're leaving so much on the table in terms of power gains because of lazy "fuck it close enough" engineering.
Like I understand that it's meant to be simple and easy (or easier) to install, but it skips so many of the hallmarks of a good turbo setup that I just... ick. Do not want.
>>13984453
Yes, you don't know anything about turbos. It's a LOT harder on stock cast internals if you boost an engine with too high of a compression ratio. If you upgraded to forged pistons and rods you could do it, but not otherwise. You'd notice that 99% of factory turbo engines have a lower compression ratio than their NA counterparts if you'd actually look.
>>13984490
>I just parrot shit ignorant people say
yeah
keep being retarded
>>13984499
Can you provide a source that proves otherwise?
>>13984504
its literally all in the tune and setup
hi comp + turbo means jack shit
its basic knowledge
>>13984453
>>13984499
You sound like quite the expert
>>13984490
That's not even the main issue, even with a feeble amount of boost it's going to detonate running on 92, you can't retard the timing enough for the engine to deal with that kind of effective compression ratio on pump gas.
>>13984510
seeing as how you prove yourself to not know shit on a regular basis its always safe to assume you dont know anything
now is not an exception
you sound like youre stuck in the 70s
its perfectly doable to run boost on 12.5 and pump gas
>>13984432
Just retard the ignition timing more. It's DI too which can have higher CRs and resistant detonation. There are a couple DI turbo engines with over 11.1 CRs. With conservative timing and boost levels it should be fine, or just some alcy injection.
>>13984524
Oh now I understand with your expert explanation
>it's all in the tune bro
Seems like installing that CAI imbued you with a deep knowledge of effective and dynamic CR
>>13984536
Sure, if you retard the timing and lower the boost enough it will work, and be a complete waste of time in the end to go through the trouble of a turbo setup to make 15 more hp on pump gas. Here's the point where someone links a youtube video with an FRS making 300hp on E85, with a new bottom end, or just no added info at all, "proving" that turboing a 12.5:1 engine and running it on pump gas is a good idea.
>it's all in the tune
>>13984453
you want to tell honda, toyota, bmw, mercedes, vw and probably everyone else that they're doing it wrong.
>>13984477
this.
poorfags, when will they learn?
>>13983608
cause expensive =/= good.
>>13984432
modern engine management has made this a rather easy feat to achieve. has come a long way in recent years. pull lots of timing add lots of fuel and you get a turbo car that has all the benefits of boost while not having the shitty bottom end due to low compression.
>>13984504
Do some research. He's right. high comp motors are almost preferable to low comp stuff nowadays with aftermarket gear. all about that cylinder pressure n shit. more compression means easier power as long as your tuning system can deal with it.
>>13984510
No it's not.
>>13984607
nearly ALL systems pull timing with boost. it's how you keep shit from detonating, even on low comp builds.
TL;DR it works. There's no reason to cry about this setup, it's a cheap setup. It's effective. If you want a race car, yeah you'll have to change pistons and probably want to drop more to 10.5:1, add forged bottom end, etc. but in terms of going faster and getting your car on boost, this shit is fine.
>>13984664
comeon on man, you should know better than this.

>Living in a fail state like California
Seriously, fuck your car laws. I visited some family there for 3 weeks and got pulled over because I had out of state plates and told if I was going to stay there for more then 30 days I needed to get an emissions test... Cop said he has seen me driving around for over a week blah blah blah.
A few of you guys seem to have a fundamental misunderstanding of what retarding timing does. Let's say your ECM has set the timing at 15 degrees BTDC. You introduce some boost and the knock sensor picks up detonation and it retards to 11 degrees BTDC, engine runs normally. You can't just continually retard the timing more and more as you add boost, because at some point either
A. ignition is now happening after TDC completely negating having boost and causing other problems
B. it still detonates because the cylinder pressure is high enough to cause pre ignition before the spark fires off at all
>>13984703
no I totally agree with you, I'm from the South and have visited California once and it fucking sucks there.
I'm just saying it's CARB legal, meaning it would pass an emissions test anywhere and also that it doesn't puke catless exhaust everywhere.
>>13984777
Heat is a major issue. No intercooler, compressor outlet close to throttle body. They put this thing on the dyno a few seconds at a time, di or not, magic tune or not. This will not make that much lower after being run hard for a while.
You can't swap a dohc legacy or impreza turbo engine in there? Nobody makes low comp pistons?
>>13984777
Wait, hold up, an ECU can retard timing so far that it'll ignite after TDC? I thought that it only retards to TDC and any bit more than that would just be pointless.
>>13984432
>heartbreaker
yup, knew this dumb faggot would be here
>>13985824
It takes a moment for the flame front to spread across the combustion chamber. Combustion doesn't happen instantaneously when the spark plug ignites. Milliseconds matter when the crank is rotating 100 times or more per second
>>13985687
I was watching a bloke on... maybe one of the /DRIVE videos who developed turbo kits for the BRZ. He was quite adamant that the BRZ motor was a much more rewarding platform to modify than the earlier EJ motors. It can apparently sustain a lot higher compression that the earlier motor, due to combustion chamber design and possibly... DI? I don't know that much about BRZs, I think they have DI...
>>13985824
TDC is just a reference point. Going after TDC would be unusual, but not really significant. If you're trying to run a very high compression motor on pump gas, it's a possibility.
>>13985913
Of course Crawford has a reason to boast about the BRZ engine because that's their marketing stake in what they're selling. Some of it is crap, right now they're selling a cheaper turbo kit without an intercooler.

Lol, yeah I guess that's why everyone wants to live here. The south is a fucking shit hole.
Also carb, who cares? Just keep your stock manifolds in the attic and put them on every 2 years. It's a non-issue except for keyboard warriors who don't wrench.
>uses the stock manifold
for what purpose.. and how is that even possible.
>>13983604
Maybe just buy a real car?
Just get a speed by design kit. It's basically a clone of the greddy kit with an upgraded Mitsubishi 20g turbo. It's $3k and has a manifold, intercooler, and bov. You can then get the openflash oft350 upgrades for it which include a new maf sensor and cold air intake. I think theyre like $300. It'll make ~280whp on 91. With injectors it'll make 400 on E85.

I was actually thinking of getting a BRZ and putting one of these in. Same company but more advanced kit. Gud idear?

if this came with 10:1 CR no one would bump it up to 12.5 because it's more efficient.
people might be making it work with stock CR but that's only because poor people llike to do stupid things.
>>13984477
>I will give them props for a rather elegant solution to using the stock manifold and exhaust
that's all I meant, the lack of an inter-cooler dumb but is available if you toss more money at them. This is just aimed at cheap asses so they can claim they have a turbo.
FYI most 3800 turbo kits reuse the stock manifolds and mine dyno'd at 400 WHP and cost as much as this kit

I think you would just need to run an e85 tune or run a methanol injection system. Otherwise stick to the low boost sub-200 horsepower to the wheels.
