I am thinking about going to a turbo upgrade.

At the moment this is what is done to the car:

- POD

- Brass button clutch

- 3" from the turbo

- Short Shift kit

- FMIC

This is what i plan to do after the turbo upgrade:

- Injectors

- Cams

- Fuel Pump

- Power FC

- Suspension

What turbo would you suggest and what price is it ruffly.

I have been told with the stock turbo and some modz i cant get anymore than 220RWKW.

I want between 250RWKW and 350RWKW, so please advise the right turbo and modz for my needs.

When i planed my turbo upgrade, i wanted it to look as std as possible so i bought a 2nd hand hi-flowed R33 turbo and fitted the VG30 exhaust housing (a R34 hiflow is equivalent and doesn't need the VG30 housing)

My mod list includes variations of all your above mentioned items but i also had my head "race ported". Even though this has given me more flow, i now realise that it also has made the combo a little laggier, but i have no regrets ;).

End result: 270rwkw@15psi

Standard bottom end; so we stopped tunning at 15psi, then lowered it to 13-14psi to make a reliable 250rwkw and fine tuned the setup at this level.

theres a massive difference between 250rwk and 350rwkw so you should think carefully before deciding, the cost difference is around 10k.

250rwkw it would go for hks gt-rs or garret equiv, z32 afm, 550cc inj, powerfc, heavy duty clutch, tyres, suspension work, cold air intake, intercooler, boost controller, 3.5" split dump zorst and cat back

for 350rwkw it beyond the safe internal limit for rb25

so youll need to open it up to safely make that power.

ie: cams, pistons, injectors

you need a larger turbo (more and more lag)

with forged pistons, cams most likely

bigger clutch, better suspension work

and so on

as the power graph increases linerally the cost graph increases exponentially.

Im new to this and was just wondering what mods id need to fit a Garret T28 to my R33 GTS25t (RB25DET) without ending up damaging the engine ie-FMIC,Boost controller etc planning on having all these but wondering wether its safe to do them one at a time or wait and have it all done at the same time, my stock turbos on the way out so was thinking of fitting the turbo first and the rest later is this wise/safe any feedback would be apreciated

T28 isnt bolt on.

Better to purchase one that it IMO. Ease of installation saves costs.

Please search for more info on upgrades and what you need

OR read these threads below, all the info you need is in the second link for supporting mods.

    • Ah right. Maybe my rb just loves chewing through batteries lol.
    • On the R34 can't you just unplug the IACV? This is the way I've always done it on the R33. Disconnect IACV, get it idling around 650rpm, and then do a power reset on the ECU to get it to relearn idle (factory ECU).   The big reason no one has touched on as to why you'd want to get the base idle right, is that it means the computer needs to make smaller adjustments to get a good idle at 700-750rpm.   Also, cleaning the IACV won't normally make the car suddenly idle lower or higher. The main issue with the IACV gumming up is that the valve sticks. This means the inputs the ECU gives, aren't translating to changes in air flow. This can cause idle choppy ness as the ECU is now needing to give a lot of input to get movement, but then it moves too far, and then has to do the same in reverse, and it can mean the ECU can't catch stalls quickly either.
    • 12.8 for a great condition, fully charged battery. If the battery will only ever properly charge to about 12.2V, the battery is well worn, and will be dead soon. When I say properly charge, I mean disconnect it from the car, charge it to its max, and then put your multimeter on it, and see what it reads about an hour later. Dieing batteries will hold a higher "surface charge", but the minutest load, even from just a multimeter (which in the scheme of things is considered totally irrelevant, especially at this level) will be enough over an hour to make the surface charge disappear.   I spend wayyy too much time analysing battery voltages for customers when they whinge that our equipment (telematics device) is causing their battery to drain all the time. Nearly every case I can call it within about 2 months of when the battery will be completely dead. Our bigger customers don't even debate it with me any more ha ha ha. A battery at 12.4 to 12.6 I'd still be happy enough with. However, there's a lot of things that can cause a parasitic draw in a car, first of which is alarms and immobilisers. To start checking, put your multimeter into amps, (and then connect it properly) and measure your power draw with everything off. Typical car battery is about 40aH. Realistically, you'll get about half this before the car won't start. So a 100mA power drain will see you pretty much near unstartable in 8 days.
    • Car should sit at 12.2 or more, maybe 12.6 or 12.7 when fully charged and happy. If there is a decent enough parasitic load then it will certainly go lower than 12.2 with time. You can't beat physics.
    • Ok guess I can rule out the battery, probably even the starter and alternator (maybe) as well. I'm gonna clean those leads and see what happens if it's still shit I might take it to an auto electrician. Unless the immobiliser is that f**king heavy, but it shouldn't be.  If I start the car every day, starts up perfectly never an issue. Isn't 12v low, shouldn't it be around 12.5v?
