Reworked K04

[azokaei]

So with my mods what should i set the Reworked K04 turbos boost at, my goal for the car is acheiving as much hp without sacrificing relability.

Current Mods:
-Corksport DP
-Custom Mid Pipe
-Forge BPV
-Cobb Accessport
-HPS Cold Air Intake
-Resonator Delete

Also i am going to be getting a custom tune after the install, as well as WR oil catch can

I, personally would set her at stock boost levels. I dont like the idea of upping the boost unless you have a built motor. These cars already boost higher than a lot of cars that are tuned in the aftermarket.

With your mods, you will move a lot of air even at stock boost levels. I would leave it at that until you can get your tune done, and even then it won't be necessary to go much higher to make a lot of power. The biggest change you should notice is the powerband going up a lot higher.
You want to give a lot of consideration to upgrading your intercooler. It is going to be a weak link for you. The one bottleneck left.

Thanks for the input, repped

Well with the stock map i have a lot more knock than on the Stage 2 Map which ups the boost to 18.5 then tapers it down.

Also i will be investing in an intercooler once i get the money for it, I am currently talking to Treble Racing about which intercooler to invest into.

you can see my mods below and im shipping a k04 to PG as soon as it gets to me to get reworked and the cobb tuner i had tune my car the first time was able to make 291 HP on another speed with just fuel pump internals, cobb DP, and an intake and thats only hitting at MOST 17 pounds of boost. i am looking to get that same boost and with how freed up my intake and exhaust is ill be looking at hefty, but healthy, HP and boost level. and DEFINITELY invest in an aftermarket TMIC or FMIC. your car will thank you.

 

[azokaei]

so which one is more vital a new tmic or a custom tune?

You need a CBE, fuel, and an FMIC before you can really take the next logical step up to a reworked K04. It would be a great mod though, no wacky boost spikes due to a teeny wastegate exhaust port, and spools up really quickly and helps flow air even better than stock. I would get it and set it at stock boost levels. But that's just me, I want a pig rich, grandma conservative tune.

 

[azokaei]

why would i need a cbe? gains are minamal and the stock cbe is barely a bottleneck

After you start flowing past 300 whp, you will need one. It becomes a restriction right around that point. And why not finish off that nice mod list and exhaust you have now with a good sounding CBE?

my ears are burning... or is it my eyes in this case(flame2)



yeah I was just thinking about your build situation today and i think its best even after you next set of mods, not to push the boost any higher than 17-18psi.

Ive already had a couple instances where I've spiked at or close to 21psi, most of the time it will spike to high 19 or 20. and again mine is just a 17 psi tune.

even though you have the upgraded IC I wouldnt go much higher in the boost department unless you have the Rods and pistons to support it.

Personally, I don't want to push past stock boost. My goal is to be fully bolted on (DP/TP, CBE, SRI, TIP, BPV, FMIC, Pump internals, Turbo manifold, Reworked K04, CPE SB... ect...) running stock boost with a super conservative tune to shift the power and torque curve up so I don't have gobs of torque below 3,000 RPM. If I see about 300 WHP, great. I'd rather do it my way than get a TBE, tune, fuel pump, and just push the s*** out of the stock K04 to get 300 WHP.

 

[azokaei]

The only reason why i dont want to do a cbe just yet because you only probably only get like 5 whp and a lotta tickets along with that. And i think it can handle over 17 psi because there are plently of people running gt3076r turbos on stock internals. From what i've been reading Speed3 blow when they go on long trips and build up a bunch of oil and then cause the motor to blow. Also the K04's always spike higher than what they are set for a split second, isnt it boost creep what to look out for. Not trying to say anything against what your saying im just stating what i've read over the past couple of months

I understand your argument for the CBE, but it does become a bottle neck after 300 WHP... you will have a restriction there if you don't address it. The people running safely on GT30s have very precise and safe tunes so they don't load up the motor with torque and power down in the low rev range. The EGR valve recirculates exhaust back through your intake and after cruising for a while it is advised to build up revs gradually to flush the exhaust gasses out of there. Excess oily residue in the inlet and coming through the PCV breather tube is due to the poor PCV system and bad fuel dilution of the oil (known to be a problem on MZR DISIs). A catch can will help filter out this mess rather well. I am also a huge proponent that the K04 can be a definite cause of blown motors amongst other problems. With a catless exhaust, crazy boost spikes are seen and that can be very harmful to the engine if not addressed. I think the stock turbo is actually what can be an aid in causing blown motors, and that people running more conservative, stock like, boost levels with bigger turbos are actually better off than those with the stock K04. That's why I rep the reworked K04 so much. Doesn't smoke nearly as much as the stock turbo, gives a nice bump in power, it flows exhaust/air better, and you don't see that rediculous, motor blowing boost creep/spike.

Ok wow thanks for that info yea I'm getting my wr oil catch can installed soon and I will be getting it tuned soon after I get the reworked k04 then I'll be getting a new tmic or a custom fmic. But since money is tight rite now and since I am getting a good deal on the reworked k04 I'll get that and a tune running most likely 17-18 psi which shouldn't be too bad right? I'll also ask the tuner to see what he recommends too

I really appreciate your guys help and input as well

If ur not totally set on a Reworked k04, u should also check out PTP's SST and the route imgoing BNR turbo

 

[azokaei]

I am already set on buyin the PG Reworked K04 due to the fact that PG makes great stuff and has good reviews and i am also getting it used at a fairly reasonable price. also what kind of whp should i gain running 18psi on the reworked

hard to say...all depends on other mods you have and even the temperature outside lol. and the intercooler would help your cause too. a cool engine is a happy one.

Nobody mentioned upgrading the mani?
