How Should I Go About Performance Rb25 - Rb30

[Stealthynsa]

i have a n rb25 and ill be adding

forged conrods and pistons

larger injectors

external wastegate

new cam gears

microtec lt-12 ecu

justjap FMIC 3" piping

turbo back 3" high flow exhaust

fuel pump and uno just basically all other little things

but i was thinking should i change the block to an rb30?

cause ive heard of people talking about things like that

cause i dont want to be stuck with a 2.5L

if all i need to do is grab a few things from an rb30...

tell me what u recommened i do here

btw its a r33 gts+t

what are you trying to achieve? how much money do you have?

how much power do you want to make? what turbocharger do you want to use?

i have a garret gt30 bb turbo. i will be upgrading that...

i want as much power as i can get but keep it a street car

looking to run low - mid 11's

even lower if possible.

but i want to know do u recommened changing part of my block or changing the head?

go read the RB30 specific section at the top of forced induction

it would have everything you need to know about the 3 litre build and best practices

theres also a sticky thread on rb30 turbo packages and the power they make

If you cant run a low 11 with a GT30 then there is something wrong with the way your driving

A GT30 will make between 270-330rwkw which is well and truely 11's territory

Other than that - do a search mate. Pros/Cons of 3ltrs vs 2.5ltrs... costs, issues, its all been covered in massive detail in past threads.

I have been running a RB30DET for about 6 years now, and i only suggest to people that they go RB30 only if their current engine is no good and not re-usable or they want to go for the big torque engine and not too worried about the cost.

RB30 is great and powerfull but they are a bit of a pain in the ass to get running and setup to work correctly.

For your goals a RB25det with a GT35r or t04z will be fine.
