so up until now i have these parts not yet installed

1- Greedy style manifold + 80mm Throtel body + Fuel Rail

2- Aftermarket Turbo 50 in size

3- NGK Iridium BCPR6

4- RB25DET Gear Box

5- r32 diff + Cusco adjustable Toe control rods +aftermarket full adj suspension

6- Blue pin OEM ECU (r33)

7- 3" Intercooler + HKS SSQV Blowoff

If money is tight sell the following to buy things you really need:

Greddy style manifold, 80mm throttle body, fuel rail, unknown turbo, OEM ecu, Tomei fuel regulator and all of 9

What you need as a minimum:

Link G4 computer + mac valve for boost control OR PFC + Z32 AFM and boost controller

Decent turbo with (if necessary) wastegate mounted on stock manifold.

Assuming you are running on petrol some 550 side mount injectors

3in turbo back exhaust

Probably a set of new OEM or Splitfire coils.

Good intercooler (you don't say what kind you have)

Good tune

  • Like 1

NOS... two of the big ones.

But seriously, your tune must be good. Try an aftermarket ECU

Thanks Mate im trying as hard as i can to get good numbers

You are missing.

Decent turbo

Proper engine management.

I guess so

You need a decent throttel body...

But yeah, Turbo, ECU, Exhaust.

Maybe E85 if it's available?

It's hard to find one here :(

Link G4 is really costly + no good tuners around

​any brand recommendation ?

Yep Nismo 555cc

3in turbo back exhaust

can i stick with 2.5" (to keep it quit as possible)

Probably a set of new OEM or Splitfire coils.

I'm trying to get those

Good intercooler (you don't say what kind you have)

aw sorry the intercooler is Apexi

Good tune

Hard to find one around

Got more details on the Turbo 50?

I hope this will help

  • Intake Inlet/ Outlet: 4.000"/ 2.625"
  • Compressor:
  • Trim: 60
  • A/R: .70
  • Inducer: 60.30
  • Exducer: 78.00

    Turbine:

  • Trim: 64
  • A/R: .50
  • Inducer: 67.00
  • Exducer: 58.80
  • 2 weeks later...

ok guys after a few days of searching i couldn't come up with a clear answer for this

i wanted to upgrade my engine injectors so i found some good names

like 550cc nismo - 750 denso - 650 bosh aside for that

what is the right one to chose for my application i mean to have a sweet 400+ without risking

oh and i've changed my ECU and i bought Link G4+ (GTRLink) ....

I have a S2 RB25DET. It makes +-340hp on 0.9bar and just over 400hp on 1.2-1.3 bar boost. Supporting mods are the following:

Garrett GT3071R 0.82AR mounted on stock manifold with external Tial 38mm wastegate

76mm exhaust with 2 Magnaflow silencers

600 x 300 x 76 Autobahn 88 intercooler

1000cc DW sidefeed fuel injectors fed by a Walbro fuel pump, stock FPR

Stock intake manifold with front-facing standard throttle body

Greddy Type RZ blow-off valve

Mishimoto R33 radiator, Nismo thermostat and SPAL electric fan

Rear head oil drain, winged and baffled sump

Link G4 Xtreme management

AEM water & methanol injection

I forgot to add that it makes full boost by 3100rpm in 4th and 5th, about 3800rpm in 1st gear.

Thats a cool setup but again 1000cc ....

i just bought the 550cc from nismo and i will try to hit this number and i hope i can

for the turbo money is tight to buy one of those Garrett GT3071R monsters any other brands recommendations ?

i will not replace the intake manifold hmmm lets see what will happen

but anyway thanks mate

Get 800cc power enterprise dropin injectors.

Adaptronic plug in Ecu would make tuning alot easier. It supports 3 bar map sensor so no AFM

ATR43SAT Ceramic Ball bearing Rb Bolton turbo. That makes 20psi by 3550RPM 4th, maxed at 424rwhp internally gated on P98 fuel.

Ok, this is the important bit, or you won't make my power:

4 inches induction pipe

PWR 600x300x81mm cooler

3.5 inches turbo back exhaust.

a Good tune

Price on atr43sat cbb if u don't mind telling?

Power Enterprise injectors are absolute junk Tao!

At that rate you might as well get Five O junk too lol.

Better off with Nismo 740cc injectors and be naughty and set the base pressure at 3.5 bar.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
