Hi All,

the mods i have r

3.5" Exhaust

Hybrid FMIC

Apexi Power FC

Air Filter

Fuel Cut Defender

i was looking at the Hybrid T3/T4, but would really love something bigger that wont max out my injectors.

if you can let me know what turbo, specs, price range and amount of boost i can run with the above mods, that would be great.

thanks guys

yea thats all god guys and id love to spend that much and i could but, i have been told if i put a T04 turbo on my injectors will MAX out at around 10 PSI, and i dont really want to get injectors, im after something like a T04 , nothing too big, or even a ball beariong T03/04.

i could spend more but i just want to spend a little for now, while i have heaps of other things on,

Would a T04 max out my injectors? i would like to run about 14 - 20 PSI ( in that range)

I was told I can put a 2535 without upgrading my injectors, someone here in the forum has done it and his injector duty is only about 85-90% from max. Not sure how much boost he runs (maybe 0.9 bar). But even a small 2535 has boost efficiency above 1 bar (14psi). Can't remember how much, perhaps 1.2 to 1.5bar.

Just get a good fuel pump, like a GTR one (cheap 2nd hand) or a new Bosch 040 if you can't be bothered to get 2nd hand parts.

I know you dont want to hear it, but even getting everything 2nd hand will come to more than $1,300. doing the turbo thing isnt cheap! when i did mine, like you i didnt want to spend much at all, but it just isnt possible. getting a small turbo (2530) needed the fuel pump and regulator to be changed, not to mention small things we all like to forget when performing this upgrade, like oil and water fittings for the turbo, intercooler pipe modification exhaust/dump mods, the list goes on.

i thought after i spent $1500 on my turbo that there wouldnt be much more to spend on the transplant - $500 in fittings and line - $300 for a reg - $400 for a pump $200 cooler pipes. it ends up getting pricey regardless of whether you go new or 2nd hand.

Maybe put the money away and save a little more so you can do it right the first time, it gets even more expensive when you have further plans down the track...

good luck with what ever decision you make!

I'm a bit confused :D

Do you just want a bigger turbo cause it's bigger, or do you want more power so your car's quicker?

Have you thought about what power goal your aiming for?

Once you workout what power you want, then you can look at what you need to do to get you there. Remeber that power isn't everything, sometimes the money is better spent on a good alignment and good tyres etc...

Just something to think about cause I think $1300 is going to fall short for a turbo upgrade.

BTW: A TO4 turbo won't be a bolt up turbo, so your looking at a different exhaust manifold and dump pipe, not to mention different oil and water lines :P

robos - no, no and yes

the only thing that bolt straight up are the manifold flange, exaust and intake pipe.

i had to get fittings for all water pipes, oil lines and intercooler pipe. so it ends up costing a fair bit

eav00l: Quote "if theree are anymore suggestions please let me know" Bendigo bank have some good interest rates if you deposit over $1000 get it in there and start saving :P

When I bought my car it came with a CGC stage2 450HP upgrade allready done to it, it's probly your best option as everything will bolt straight back up perfectly. I'm not exactly sure if my car has standard injectors or fuel pump and I cant check as it's getting work done to it and not in my garage, but I've seen the turbo pump out 16 pounds with no problems at all and comes on boost strong at 3,400 rpm and really throws you back, enough to spin the wheels in the first few gears without droping the clutch.

    • 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.
