R33 Turbo Upgrade.

[sindows]

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.

Thats al,

How much did the turbo cost you?

What modz have you done?

[Sass]

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.

You have a stock motor or a built one?

stock - 270rwkw limit - GCG hi-flow is perfect

built - 300+rwkw - GT30/35 depending on what you want out of it

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

[R31Nismoid]

T28 isnt bolt on.

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