LiquidSilverSpeed's GT3076R Build
 

Waddup. I've dailied a bolt on, billet wheel'd K04 for a year now (and dailied the stock K04 for 3 years prior.) and I'm bored of it. I've pushed it pretty hard this last year, to the point where it's smoking now, so it looks like it's time for an upgrade. I'm gonna get a GT3076R, Tial 44mm, HTP 3.5" intake, and exhaust manifold slapped on in a week or two (on top of what's already in my signature.) I'm going to go with Dizzy to tune it. Can't wait to dyno it and show y'all the results. Any guesses on power? Doing both 93 and E30.

Cool! What'd you make on the billet-wheel K04? I'd love to see a dyno plot (even VDyno) for comparison to a standard K04, or one of the BNR/CS drop-in turbos.

Unless you've got some additional (aux) fuel, I doubt that Dizzy is going to push you much beyond 400whp if your car can manage that much. I'd guess somewhere in 350-380whp range would be reasonable for your mods with the GT3076R.

No idea, never dyno'd it. I'm gonna guess 330/350 though? All I know is my butt dyno says it pulls harder than the OEM K04 lol. Those BNR/CS turbos are definitley an upgrade over my billet wheel K04 however, yes the upgraded turbo internals do make a difference, but nothing as drastic as those.

But oh no, even 400 seems like too much for my goals. My motor is stock and I'm never going to build it, I just want a fun street car. 380/380 on E30 is honestly my goal. Mostly doing it for the turbo and ewg noises.. Jesus I'm a ricer.

which mishimoto core are you running? I see a lot of people run the M line core but on paper, the S line seems like the better choice. Thats the one I want but mounting may be a problem. Are you using a custom crash bar? or one of the ones the many vendors make?

If your goal is just under 400, the BNR S4 has your name all over it. And it's a "simple" bolt-on affair. You can reach your goals with the S3, but you'd be pushing it pretty hard. The CS turbo can get you there as well as its sized somewhere between the S3 and S4.

Any of those 3 turbos will spool quicker than a 3076.

I got the M Line, it does the job for what I need. Yes the core is big.. mounting it on a CB may be a problem worth finding the solution to.. I'm irresponsible and have been running without a CB for half a year now. One day I'll muster up the motivation to somehow put one on.. one day.

I'm sure they're better turbos for my need, but I'm only getting the GT3076R because I'm buying it as a kit, someone in my local nator is selling me his old set up from his Speed 6:

GT3076R
Tial 44mm EWG w/ Dump tube
HTP 3.5" Intake
Exhaust manifold
Oil feed return line

For $1450. Can't pass that up.

Maybe I missed it, but which exhaust manifold is it?

He said tubular? But he's not even sure himself. The entire kit is still on his car, he's taking it off this weekend and it's coming on my car the 21st.

I'm guessing it's the eBay manifold with an ATP bolt-on 3076 turbo.

No clue on the mani, but the turbo is a Garrett.

Ya, the ATP bolt-on is a garrett with a swapped out turbine housing to match the K04 manifold flange and stock downpipe flange.

If the manifold output flange is the same as your Mazda, you got an ATP/Garret kit (Most likely) and if not, you got a custom manifold for a standard turbo flange.
The second one gives you more options for the next turbo.

I say that if you don't like the lag of an old 3076...You could get same flow with smaller wheels these days and because it is already above your goal you could even go smaller.

I bet in a short while you will be looking at the cost of forged internals to open it up....

^^what he said.

I remember the days when I thought 400whp was plenty.....even though I only got up to mid-300's.

Now my long term plans have me looking hard at the PT5558 Gen2 pushing 500+.

Ah. I didn't know that, cool then yes that's the case, it uses stock downpipe flange.


In that case yes ATP/Garrett kit, since it uses the same flange. Good to know. I think I'll be more than happy though and won't be looking to build the motor any time soon. I've driven it on K04s for 4 years now, I'll probably be another 4 on this 3076 lol

Not sure if this is how you do it, but here are two pictures of the manifold/ewg

we cannot tell by installed picture. Take one when you have it in hands or put both manifold side to side before install

Will do. Do different brand manifolds make a big difference on our cars? Only thing I think would concern me are the welds over time

Depending on the version of eBay manifold. The earlier ones did have weld failures. They're on V3 now and are much better...from what I've heard.

I read about uneven surface too but it can be easily checked with a solid ruler or something straight and a filler gage. But if you don't see black exaust leak it could be a good sign that it is ok.

The 6 it's coming off of is tuned by Nishan, and he hasn't seen anything of concern in his logs, so I think it'll be okay haha

Well, the kit is on.. holy.. the sounds the car makes now. Insane. So excited to see what she'll feel like by the end of the tune.

Thats a hell of a deal. I went 3576 on stock motor because i thought the k04 was bad. No motor was. Fj built now. But 2015 i drove from Pittsburgh to San Antonio for a TS gtx3576r, steedspeed ts top mount mani, perm dp and wg dump, shortened & welded cp-e ic piping with a giant custom intercooler, 5th port, 6 port SS controller, and 3.5in intake for $2000. Became good friends with the dude over the years. When i picked up the parts i stayed at his place for a few days and worked on his car. Shit was a great couple days. You can definately go 3076 on a stock block just keep the torque down. Ran my 3576 for 6 months at 18psi and 306awhp on a stock block that burned a quart a week. I know jakes gen 1 made 533whp with a 6266 stock block and ran great for years. He had a built motor waiting but stock block would never give up.

the risk is: ....what if 1 more psi...

Hows the fitment with no crashbar? So its just being held up by the clamps? No leaks?
