Need RB25 advice

[tscharf]

Just picked up a rb25 s14, as of right now it's stock with an exhaust, intake and radiator. I'd like to get it to around 300whp cost efficiently, what mods should I do to get me there the easiest. Please don't troll my thread

[BigKriss]

Running an RB25 Neo in mine, stock cast exhaust manifold, Freddy intake, 450cc injectors, GT3582R Turbo, Garret core inter cooler , 0.8 bar boost. 278 wheel hp.
It is my daily, run her at the track and generally abuse the heck out of her.
Engine is an unopened import ..I did however do the cam cover oil mod before dropping her in..
These are sweet engines..

You don't need any of that stuff. A local car here made 300whp with only a Freddy intake manifold 550cc injectors and mid mount. Everything else is stock. Stock turbo on 11lbs. You can just get a good tune

Gt35R and only 278whp? are you pushing like 5-6psi lol?

[tscharf]

where can I find one of these freddy intake manifolds, I looked on ebay and can find them

You need to look harder. It took me about a second to find them.

rb25 intake manifold in Air Intake & Fuel Delivery | eBay (http://www.ebay.com/sch/i.html?_trksid=p5197.m570.l1313&_nkw=rb25+intake+manifold&_sacat=0&_from=R40)

What are you guys using for tunes?

my bad, I just typed in freddy manifold
would it be worth it to pick up the manifold/fuel rail combo or are those fuel rails junk

[BlewByYou]

Cheapest rb20 nistune but you have to wire your vvt to a switch. Best Apexi power fc, AEM, haltech... depends on your pockets!

[MA MOTORSPORTS]

Apexi has a rb25 d-jet ecu that wont break the bank and you can get rid of the MAF. We just tunned one last week and its awesome!!!

we also offer rom tunning as well

[omgRWDgoodness!]

Finally, someone with half a brain. Seems to be an influx of retards asking about RB20s lately.

Must be that South African tuning :ugh:

I believe ISIS and GodSpeed/CX Racing make knock-offs, but I dunno since I have a real one.

[PrimeDirective]

You dont even need a freddy intake manifold for 300whp.

[tscharf]

I think I'm gonna try and find a hx-35 and some supporting mods (intercooler, injectors, fuel pump, regulator, power fc, intake manifold)
Opinions?

[!!chuy!!]

my brother and i have rb25 s1 in our s13's and he tuned his with apexi safc pushing 10 pounds and made 302 hp.
mods:
fmic,
3''downpipe and catback,
walbro fuel pump.
virtually STOCK!

I'm running NIStune with z32 ECU. I wouldn't go the RB20 ECU route as there is no VCT controller.

Tempting haha

Do NOT go SAFC. It's garbage and a waste of money.

Is this picture pre cas install or do you have some other voodoo going on here? Granted they are not a high failure part but I have still been looking to eliminate mine.

To Tscharf go with Nistune in a rewired Z32 ECU unless you can manage to find a PFC. SAFC's are as stated above a waste of money and so are piggy backs.

[MA MOTORSPORTS]

save your pennies and go with the power fc d-jet you will love it. you can get rid of the MAF with the d-jet. You only want to do this once so i would do it right way. i can get you a good deal on pfc because we are direct with apex

[tscharf]

Just bought a power fc with datalogit and z32 maf, now I'm on the hunt for injectors

[MA MOTORSPORTS]

are you using a top feed rail or stock?

^^iam with this guy!!

[BigKriss]

wait?? wheres your cas???

In the bottom drawer with all the other crappy CAS`s !!
Running 60-2 crank trigger.

For all the pimply faced replies as to the GT3582R I`m using.
0.7 bar , daily driver. I am no drifter, preferring track days instead.
1.5 bar boost, almost un drivable as most of you blokes would know.
462 wheel hp.Injectors were replaced with smaller 450cc ones lately while waiting for a new set of 700,s..
So 278 hp with GT3582R for now.
