New T04Z Install Pics
 

Well everyone else is sharing lately, so I'll add to the turbo fest as well.
Everything is all buttoned up just need to get it down to Chris at Banzai Racing for the tune.

Where did you get the To4Z from? Sure its not just a BB to4R with a bullet style antisurge compressor housing?

to be a proud member of gangsta rotaries you should know this ;)

Thanks,
I 've been around the block more than once.

that's one nasty charge pipe.

Did you have chris do all the work on that. LOOKS AWESOME! I'm goin in next thursday do have some stuff done, is it still gonna be there?

Looks tight dude! Sweet, no clearance issues with the HKS shorty manifold? What size turbine A/R is that and what blanket? Can you please post results at 15lbs, if possible?

Rotaries should use a non surge cover on TO4Z
 

The TO4Z's i use and specify have no surge holes, these reduce spool rate, they reduce PR te tubo can produce, they reduce efficiency, they are bad news all round.

They were only ever created to increase map width when use with a small turbine and use on a small displacement engine that suffers from compressor surging under throttle at low RPM (too much boost pressure and not enough corresponding flow rate).

If you want more data from another field go onto supraforums.com and look at the anti surge delete they do for GT42 and GT47's ect & note the decreases in spool time and also inproved turbocharger performance (ultimate flow and also peak boost).

As far as I know that is 100% true about the " bullet " style ones, then again what ATP sells and what you have are two different turbos I believe..

nice I've been wondering what you've been up to, you going to the spring BBQ?

We built the engine and did some of the mods a few years ago, Finnicky installed this turbo over the winter because his last one self-destructed after a season at 20psi. We will be tuning today, the car will not be in the shop when you come in next week.

Bummer... Well hopefully there are some other nice ones in there to look at while my car cools down.

We tuned it today and surge holes or not it was FAST. Night and day difference from my last setup. As always Chris at Banzai Racing was awesome. I will try and dyno the car very soon. Low boost 15psi high 25 psi should be interesting to see what kinda numbers I get.

I thought I saw an hks twinpower, is that right? Also did you run meth/water injection with pump for 25psi?

Yes, it has a twin power and we were spraying water/meth for the 25psi tuning on 94 octane. The car spools very fast, we were seeing 25psi at 4200rpm and holding until redline

After 20psi it got interesting all the way till 25psi we started blowing off vacuum lines, and then a coupler let go. After the tune I drove it 3 hours home smiling all the way.

Its funny how things progress, with some form of extra injection.

I turn up to someone event now and look for things that will pop off its not sufficient to have vacum hoses on straight barbs especialy after they have been sitting for a while in a road car. Just becomes second nature when your running your street car around at 25, 30 or 36psi ! to find these failure points of connections that were never ever intended to see that much pressure over stock ;)

seeing a customer smile when he experiences 20++psi is what its all about, i think any single turbo owner who does not run this boost at minimum should be banned? :)

wow Im gonna get banned for not running 20 psi haha
We in the UK sh1t ourselves if we run more then 1 BAR on a single :)

Finished the AQ WI installation on my T04Z Half bridge single install, flowing about 400cc of water scaled to my injector duty, pulled out a lot of fuel and running 17psi now the car is toooo fast for the road feels about 500rwhp will know when it hits the dynopack next week.

Will have to grow some balls and venture into the 20psi zone so I wont get banned haha

^ thats great news ;)

you will get used to the power & 20odd psi is where life begins, in fact make it a nice 1.5bar 22psi haha this is what i force all my end users on and they dont hear the end of it till they finaly turn it up.

Sounds like your reaching your limits of adhesion soon anyway, I know what that feels like in a half bridge T51 with water at 20.6psi its scary !!!

Banzai is working on a 2 bar setup for the car, but with the tires spinning at 110mph it will be interesting to say the least.

Congrats on the great setup... We will see how my T04Z setup runs on my Banzai Racing rebuild too ;)

:eek:

She goes on the dyno this Friday, so we will see. The plan is to run 94 octane w/ H20 injection for 16 psi and above.

Post Video of it, I want to hear that turbo spin :)

I would like to see the IAT #'s also

Can you please list all the work done to the 13B-REW?

Here is a list of mods:

Engine:
Banzai Racing 13brew w/S4 Rotors
850cc Primaries
1680cc Secodaries
Gotham Oil pan brace

Forced Induction:
Garrett T04z 1.00 A/R
CoolingMist Dual Stage H20 inj. (50/50 meth/h20)
Greddy 3-row FMIC

Engine Management:
Power FC
Greddy Profec B

Drivetrain:
TII Diff
ACT 6-Puck
ACT HD Pressure Plate
12# Act Flywheel
Diff brace

That's the most of it.

Nice :)

I am using S4 turbo rotors in my super engine too, with slightly lower compression via some rotor porting ;)

Its the only way to go if you want to run serious boost, even on lowish boost they make EXCELLENT power !

I am going to run very similar set up to you but with 1.32 rear AR, my own water injection system and about 29~36psi boost pressure, expecting around 630~650rwhp.

And: Engine is not pinned with 2mm RA seals
Premix: Amsoil 2-cycle only

are you gonna bring this beast to the banzai cookout on the 19th?

finnicky7 - It will be interesting to see the difference in our #'s since Banzai built both of our motors, but with totally different setups.

S4 13BT w/ Agressive Street Port built using Super Seals all by Banzai Racing
S6 Rotors
T04Z 1.15 A/R Devided Manifold
Custom Devided Equal Length Manifold

And the list goes on...

I can't wait to see your #'s. You didn't have the 13B-REW Ported yet?

Opps..It has a very large Street Port as well.
I can't make the BBQ my wife is about to pop.

So you went with the 1.00A/R huh? divided or no? Why that A/R and nothing smaller or larger?

It's divided. I wanted to start smaller and see how it went. So far to 1.00a/r is plenty strong. With ful boost at 4200 what more could I want. I had a non-BB turbo before this and hated the lag.

looking forward to see your numbers i got my to4z with a 1.00 also :fingersx:

It will be interesting to see the difference of these two cars now. I can't wait to get mine up and running. Are you running the HKS or Greddy manifold?

^ Can you guys post pics of those manifolds? They are both short runners, correct? I want to see the angle of the flange (how the turbo will sit) and how close they are to the intake manifold. I know the Apexi RX6 manifold is extremely close.

Hey RICE,

could you go into this a bit for me, please? if you feel it's going to foul up this thread, could you PM me. i'd like to know the reasons.

thanks,

So where are the Dyno #'s bud???

Sorry everyone is going to have to wait a little while. Had some issues with a coolant seal on Thursday morning that finally became extremely apparent. Engine is out right now and will be for a couple weeks. But don't worry 15psi, 25psi and maybe a 30psi on the T04Z is on the horizion. This gave me an excuse to put in the new RA black seals anyways.

any type of anti surge system costs ultimate turbine speed and pressure (due to decreased aero dynamics around the comp wheel). It was as I think I posted only ever created to increase map width of a turbocharger and NOT flow or pressure ratio. This is why i dont use them and many others (notably supra people) delete anti surge housings because they are junk.

reduced flow
reduced boost
increased spool time
reduced surge (not relevant to a 13B running T4 sized turbo)

^ so you can see there is no benifits there for us at all, except a nice whistle :)

Exactly why I opted to forego the anti-surge on my 500R after some informed input from Mike/RacerExtreme7 :icon_tup:

Sorry to hear this, man!!! I had to sell my FD when the motor blew on the dyno. I went ahead and had it rebuilt to get top dollar for selling it. An apex seal failed on the new owner just after a 1300 mile break-in period. Best of luck to you!

Ya it sucks, but such is life. Nothing good ever comes easy, unfortunately.

Any news on what caused the failure?

I'll say. Could you not find any elbows? Good luck with the new motor.

Any updates yet?

I won'tbe able to re-build until end of may. Just had a baby! I'll post up as soon as she up and running.

just an update, I ran these figures on a Ozzie Dynopack
468.2 rwbhp @6.99rpm @1.3 BAR .Torque 375.9 @ 6.016rpm

What is all done to the motor and mod list?
