300 whp?

[xero1]

how much boost is require to make 300 whp? and will stock s13 sr20det internals hold 300 whp(if so how long will it last)?

[luv2spedup]

depends on what setup ur running, as far as the internals are concerned they will hold if u up grade ur head gasket and install ARP heas studs. these two things are a must

[zippitta]

Depends on turbo efficiency, turbo flow rate, head flow efficiency, displacement, the ratio of fuel:horsepower, there are so many factors. Stock internals can handle it as long as it is tuned well.

[PROJECTRB240SX]

THERE ARE MULTIPLE CASES WHERE PEOPLE ARE RUNNING COMPLETELY STOCK SETUPS (STOCK INTERNALS, HEADGASKETS, HEAD BOLTS, ETC.) WITH JUST AN ENTHALPY TUNE, GT28R (S15 T28), N62 MAF, 550CC INJECTORS, AND COMMON BOLT-ONS (3" TURBO-BACK EXHAUST, FMIC, ETC.) MAKING 295-310WHP AT 15-17PSI.

THERE IS ANOTHER COUPLE ENTHALPY USERS THAT IS MAKING 320+ WHP WITH 256/256 STEP 1 CAMS, AND 18-19 PSI.

[SILVIADRIFTR]

You don't even have to chip an ecu to do 300whp( nothing against enthalpy). These setup don't require cams or any internals but would suggest rocker arm stoppers for saftey.

Basic setup to do 300whp safely is: gt25r, blow thru z32 maf, safc, 440cc inj, FMIC, and walboro pump. At 17psi, fully stock motor 324whp and 285 ft trq.

1 step up would be the gt28r, and 550cc inj, with the same add-ons at the same 15psi will do 340whp.

An aftermarket manifold would help but not necessary. Obviously exhaust and down pipe would be needed.

My preference is this one. The only difference is t3-t4 57 trim with custom stainless manifold = 328whp 298ft trq @ only 12.5psi

IN ORDER TO RUN A Z32 MAF AND LARGER INJECTORS YOUR EITHER NEED A TUNED ECU OR A PIGGYBACK (WHICH IS ONLY A FEW DOLLARS LESS THAN A QAULITY TUNE WITH NO IGNITION PROBLEMS).

YOU CAN BUY A ENTHALPY TUNE, 550CC INJETCORS, Z32 MAF, AND A GT28R OR S15 T28 AND GET 300WHP AT 16PSI PROVEN. WHICH WOULD BE ABOUT $400+ LESS THAN THE SETUP YOU QUOTED.

Tuned ecu= 400.00 -500.00 plus tuning: Even Scott says to get a god tune on a car he needs to get it on the dyno. The programs all rom programs carry are universal and still need fine tuning once installed for maximum gains.

SAFC or Greddy Emanage- 300.00 1 hr dyno time and can control the z32 with the input control and wil control up to 550cc injectors.

Not saying that Scott couldn't do a better rom than the afc but I said basic and it is less expensive with less dyno time. Scott ignition maps are the best in the buisness for the most horsepower but we are not talking KA-T that doesn't have ignition mapping in the stock ecu for a turbo appication.

And the ROM is not less than the piggy back due to more dyno time and the piggy backs are cheaper.

I GOT MY TUNE FOR $325 AND ITS FAR BETTER THAN A SAFC THAT ADJUSTS TIMING ADVANCE IN UNISON WITH FUEL.... NOT A GOOD IDEA ON TURBO CARS, WHICH REALLY LIMITS ITS POWER MAKING ABILITIES AS KNOCK BECOMES MORE OF AN ISSUE.

Is that including the ECU reprogram and dyno time? Also, as I said above we are not talking about a Ka-T with N/A ignition mapping we are talking about sr with turbo ignition mapping. I realize and stated earlier that the ROM tune is a better upgrade than a piggy back for the reason of ignition control, but I also said that the piggy back is cheaper and requires less dyno time. Have done multiple cars with this setup with no excessive knocks on Sr's, KA-T's are a different story.

Also, the greddy emanage and safcII do have knock control.

He asked for what was needed for a 300whp setup and that is the minmum needed and will run it safely. If he was aiming for 350-400whp and up, definitly the rom tune would be suggested.

I STATED A SETUP THAT WAS CHEAPER AND WILL MAKE 300WHP SAFER THAN YOUR SETUP.... SO STALEMATE!

IT DOESN'T MATTER IF ITS NA OR FI IGNITION MAPPING THE FACT OF THE MATTER IS WITH A PIGGYBACK YOU INCREASE ADVANCE AS YOU INCREASE FUEL.... WHICH IS FAR FROM IDEAL WITH A TURBO CAR. A ROM TUNE WILL GET YOU FAR INTO MEAT OF AVAILABLE POWER ON YOUR SETUP.

So, Scott sells chipped ecu's for 300.00$ Your math doesn't add up. You said earlier that it cost 400.00 for the rom to be done to a stock ecu and then you come back and said it cost you 325.00. Then I ask is 325.00 just for the tuning or is that including dyno time and all? I guess what I was asking is what all did the 325.00 include. Also the SAFCII and the emanage have the knock control feature which was your point about making it a safer tune.

[PROJECTRB240SX]

I never once said ecu tunes were $400.... I didn't get my tune from enthalpy, I got a redline tune. That doesn't include dyno time, but If i can find my dyno sheet right out of the box it made 307whp at 16psi.

My mods are:3" turbo-back exhaust (not CAT)2.5" custom FMIC kit9.5lbs flywheel (ACT SS clutch)Topspeed intake manifoldDeatschwerks 550cc injectorsN62 mafRedline ecu205/50r15 tires3.9:1 LSD

The point I was trying to make about the piggybacks is that it limits your power making ability because when you adjust fuel you add timing which increases detonation and decreases power. The knock control retards timing and decreases hp further.

The best investment is a rom tune its just alittle more than a safc and it makes more power and is safer all around.

[kapower06]

One of the local sr guys mad a lilttle over 300whp with an pulsar gti-r turbo, s15 injectors and safc. Plus the usual FMIC, 3" exhaust, and walbro fuel pump. Everything else is stock. heres the link to his car

[toledo240]

like everyone else said its all about the tuning and bolt ons, internals are all fine. a head gasket maybe... if you boost a big turbo like the t3 all day everyday. My opinion get a turbo that is performed for around those horse power numbers. I would just do the piggyback, ec always gives trouble and i dont think there needed uinless your messin with big horsepower and huge injectors.my setup isbigfp28 ( another option of the t28bb s15)fmicfuel pump550,z32mafs safc2exhaustyou can have 300whp easily at around 17 -20 psi, you can run stock injectors and stock maf to about 270-275whp before you get your fuel cut on the bigfp28 at about14-15 psi

[RobDET]

FMIC 255 pump 14PSI on the T25 50 shot

300+ RWHP

It will last forever. (as long as the bottle is full)

[xero1]

how long will my s13 sr20det last if i'm making 300 whp(the engine is in good condition now)? here is a list of upgrades that i will do: APEX'i Metal Headgasket, arp head studs, t28 turbo, z32 maf, full 3 inch exhaust, SARD 550cc injectors, Greddy V SPL FMIC, A'PEXi SAFC II, Megan bottom mount turbo manifold. how much boost will i need to make 300whp with this setup?

[PROJECTRB240SX]

With the safc-ii you are going to need more boost than with a good rom tune.

Either way your setup will last you a long time as long as you maintain it.

[RobDET]

100 thousand miles +

I ran a 12.8 @ 110 on 13 PSI with a similar setup but i have an AEM EMS. You'll probibly see 300 right around 15 PSI

[T4 RB25det]

my freinds old 240 made 379rwhp@18psi with a blitz turbo kit, stock cams, pump gas, stock headstuds, and an afc hack

[xero1]

has anyone used a JWT ECU? how good does it work compare to a A'PEXi SAFC II

http://www.srownersclub.com/Me...e=ECU

[PROJECTRB240SX]

ITS CRAP TO ME....

TOO MUCH FUEL, CONSERVATIVE TIMING, AND $500.... GET THE ENTHALPY FOR THE SAME PRICE AND SEE A 20-40+ HP INCREASE OVER THE JWT (THIS HAS BEEN PROVEN TIME AND TIME AGAIN).

[RobDET]

Plus is JWT still only suppoarting distributor cars?
