How much power?

[evan1242]

Hey everybody have some questions on how much power do you think my set up SHOULD be making.

Build list.
S13 SR20DET
Decked block and head
Freshly honed cylinder walls
Polished crank
New bearings
Wiseco forged pistons. (86.0mm) stock bore.
Wiseco piston rings/wrist pins.
Comedic metal head gasket
ARP head stud kit.
Brian crower 272/272 stage 3 cams
Brian crower valve springs
Brian crower titanium retainers
Rocker arm stoppers
550cc injectors
Z32 MAF
Forced performance 20G turbo
ISIS tubular bottom mount manifold
Gay front mount interccoler set up
Greddy RS BOV
Apexi AFC neo
Apexni N1 full 3 inch turbo back exhaust

Just wondering what I should be looking for on the dyno.
Really hoping to get to 400 HP

Constructive criticism accepted. Lol

[srstan]

350-400ish

[army240]

Change your AFC Neo for a stand alone... Or your 400ish HP won't last long...

But with the rest of the setup... yes, you should make it!

[evan1242]

Yeah I was figuring the neo would hold me back.
I hate the stupid thing.
I was thinking about using mega squirt and spark or maybe AEM EMS.
Just so expensive! Lol

[HYPNOTIK]

Is that the Forced Performance TD06-20g?

[evan1242]

Yes it is. Bolts right up. Just have to get a new fitting for the oil feed line.

[HYPNOTIK]

That's the same turbo I have. I made 425whp @ 1.32 bar. I suspect you might make a little more up top with the sacrifice of spool with the 272's. I only have 256's. IMO, get bigger injectors and a power fc if you want this to last.

[evan1242]

Awesome! And what exactly do you mean if I want it to last? Something going to eventually blow with just the neo?

[eclipse_dsm]

lol.. That would be crazy.. Trying to shoot for 400 on AFC. Your'e better of with a ROM Tune and have AFC for fine tuning if needed. Besides 550cc can barely take you to 400whp range. If the motor is freshly built tune for something more conservative as you break it in and have more miles on the motor. Then when satisfied all is good then bump up the boost.

[evan1242]

Yeah I had it tuned for break in on a small t28 on 12 pounds. Drove about 1500 miles on that. now have the 20G. Probably will go ahead and get some 740cc. Maybe bigger.

[HYPNOTIK]

I was mainly talking about the injectors, 550's are too small for that power level. As for the SAFC, it only controls fuel. What are you gonna do about timing control? I would def look into a Power FC or at least a ROM tune.

IIRC, the Neo can't display knock either.

[evan1242]

Yeah I know. Deff don't need any unknown detonation/pinging going on. Lol.
I'll probably just settle for 350-365 for now. Can't afford a stand alone right now. Much less bigger injectors.

What is a good brand of injector that will do the job but not kill my wallet?

I would suggest not doing any head work that your looking at and go with some JWT S3 cams with RAS. That would save you a bunch of money towards your standalone, SAFCs are not a safe bet when making 400hp.

And if you are going to hone the block, minus well get get bigger pistons.. it would be the same route you are already heading

[HYPNOTIK]

Any of the name brand injectors would be fine. I'm using stock 850cc injectors from a RX7.

[codyace]

550 are going to be way to small of an injector, not to mention if you want to stick with the dial-a-boom AFC it's beyond it's control ability.

As said above, sell the junk valvetrain stuff for JWT S3 cams and stock stuff, get a JWT or Enthalpy ECU (or a tunable setup if you can afford it) and be happy. If you've not built the engine yet, I'd also ditch the cometic HG for a Apexi or Cosworth.

[evan1242]

Engine is already built.
Made 387 hp this morning...

Good numbers, I still wouldn't trust that AFC as far as I can throw it. It simply doesn't control anything properly.

[evan1242]

Ordered some decsh works 1000 cc injectors.
Also am sending out the ECU for a tune from enthalpy. Then use neo for fine tuning.

[cotbu]

Then use neo for fine tuning

Why are people still saying that!

[SLiDe_WaYz]

that NEO will cut your engine life in half.

What's wrong with doing that?
Plenty of high horse power cars use it. Saw a 2jz make 600 horse on a neo and enthalpy ecu. In person, not on YouTube. Damn near perfect A/F ratio across the board.

Not if it's tuned right and not maxed out.

[evan1242]

Yeah I didn't say I liked it. Lol.
But it will be the job done until I get something else

Not to thread hack, but I don't think I should make my own thread asking this same question, feel free to chime in everyone! Just cranked it up for the first time the other day, and it's gonna be a while before I get it to a dyno for tuning.

My build list:
Engine: SR20DET Red Top
Pistons: CP Pistons 9:1
Con Rods: Brian Crower
Cams: Brian Crower 272's
Spring Retainers: Brian Crower Titainum Retainers
Valve Springs: Brian Crower Valve Springs
Valves: Brian Crower intake and exhaust valves (exhaust are 1mm oversized)
ARP Head Studs
Fuel Injectors: Injector Dynamics 1000cc
Turbo Manifold: Full Race twin scroll dual wastegate
Turbocharger: Garret (GT3071R twinscroll, obviously)
Mass Aif Flow Sensor: Z32

I've been told this set up will be a reliable 450+ but just wanting see if anyone can back that up or give a more accurate estimate.

The list is impressive, and I think it's an e85 dream build!
What are you using for tuning?
The tuning option is what makes the power reliable, not parts.
Maybe you just forgot to mention some of the key parts.

[herbieS13]

i think you should be able to break 400 fairly easy, cant say how much exactly, im actually about to tune today also i made 390whp @ 17.5 psi sr20 2.2stroke 264 cams 2871r, and ive got a sc3431 now

[onehundredoctane]

I'm hoping for 450-500 on 98 octane, if that doesn't happen I might go E85

[onehundredoctane]

Nistune type 3 board, Pete from PLMS Developments (who make Nistune) put a base tune on it for 93-98 octane, I have yet to finish some of the under hood stuff. But I have the feeling I'm going to be disappointed when I hit the dyno.

[BNASTYs13]

550cc were running 90% dc for my on my old setup. i made 340 whp.

nismo 550cc
2871r.86
apexi l jetro
z32 maf
HKS 264 cams
HKS springs- WASTEE.. BC all the way.


if you want 380-400 safely i recomend 740cc with some sort of ems. you could always get a rom tune and keep th afc neo for fine tuning and as a form of metering.

hope this helps.

[HYPNOTIK]

Do you guys understand that on a turbo car the turbo is basically the deciding factor in how much power your gonna make? You can have 5 different setups with different injectors, different ECU's, different brand of cams, etc. and a good tune with the same turbo on all of them and you're gonna get pretty similar results. Just look up a compressor map of the turbo your using and you can guess ballpark power figures.
