Okay so this is probably a pretty common topic but I'm at a loss for where to go next with my mods so I'll start with the current list:

S1 R33 GTST

TD06 turbo

3inch turbo back

FMIC

Profec EBC

SSQ BOV

Turbo timer

Tien/Bilstein springs/shocks

OS Giken twin plate

I was thinking my next step should obviously be ECU upgrade then I thought I could probably use a box for my pod filter and some cold air but then I got to thinking that fuel upgrades might be more important first. I'm not really bothered (don't care) about asthetics at this stage and this is my first serious performance car so I don't want to pour a huge ammount of money into something I'll probably sell in a year or two.

Between now and the next big step I have a few small things planned like a catch can and HICAS lock bar, possibly an oil cooler too.

So basically my question is what's the most important thing for me to get into next? The car is just a street car and I'm only chasing a reliable 300-350hp atw but I'm hoping to see some track time and I do go to the drags a bit.

With that set up and ECU should get you in the mid 300's. Just be careful as stock internals don't take much more than that for too long, 350 as you say is good and safe. Also your gearbox would be the next weak link. They would be next major mods. Small mods would be as you say, cold air intake, catch can etc. With the upgrade of ECU you can then upgrade injectors etc too.

He clearly needs neons and a huge drift wing :nyaanyaa:

I'd be doing injectors, ECU and fuel pump all at the same time and getting a final tune.

You can't up the boost without more fuel, the standard ECU won't support larger injectors, and the fuel pump won't flow enough for the added power. Pretty big outlay but you'll finally get to crank the TD06 up to max.

hold your foot flat and see what goes first, pistons or rods, we can all place bets.. im sure there is alot of guys with alot less then 350 who's engines have gone bang, guess it depends how u drive and whos going to build it as to how long your rebuild will last, and also how heavy your wallet is....

The rods seem to be the most common weak point much over 350. Drive quiet and it will be fine over that but what is the point in that?

ECU, some will recommend PFC, if you wanna ditch the AFM etc go for a Wolf 3D.

what type of td06 are you using? (td06-20g or td06-25g and what size rear housing 8,10 or 12cm?)

I would go with the following mods:

ECU (Apexi PFC - you should be able to find a second hand one very easy, as they no longer make them)

Fuel Pump (tomie,nismo etc etc, they are all bolton and will supply you with enough fuel)

Injectors (NISMO 550cc or 740cc; because you have an rb25 get nismo as they are direct bolton, unlike sard injectors)

AFM (z23 afm + z23 afm plug)

go get a tune and depending what type of td06 you have you should be in the 300rwhp range.

Reliable depends on your tune, im running 337rwhp @ 16psi with 11:1 AFR (rich tune) (100,000km) my car see alot of limiter smashing and bashing, abuses from antilag and i do like to do abit of track work (drag,mc and drift when i can get time) AND i havn't had a problem yet

(my engine is unopen stock rb25det)

good luck

oh and if you need some help finding a second hand pfc, i can source you one

    • 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).
