What $$ Should I Budget?

[flth32]

Okay so far the car already has a 2.5 inch exhaust (turbo back?..hopefully) and a K&N pod filter.

What I'm probably going to get is...

- high flow cat for the exhaust (becuase I dont think it even has one at the moment, so I need this one)

- RB25 turbo (high flow)

- Trust intercooler

- Bosch 910 Fuel pump

- Electronic boost controller

- ECU remap

.. Im hoping I'll be able to run 11psi low boost, and 15-16psi high (is that reasonable??).

What do you think I'd need to budget? .... $2000? Much more?

Budget minimum 3k. Replace the whole exhaust with 3" turbo back. Always allow a bit extra for things that pop up unexpectedly

Yeah? Okay that sounds pretty reasonable.

And with those mods do you think the 15-16psi would be a reasonable amount of boost?

[MR 33]

Will be fine as long as the turbo has steel wheels to handle the heat!

Okay I dont even know what 'steel wheels' are... what sort of turbo would I be looking at if I wanted that?

Your stock rb20 turbo and stock rb25 turbo's have ceramic turbine wheels that dont hold together long with over 14 psi of boost. Your modified "High Flow" from slide or GCG or whatever, replaces these with steel wheels for durability.

I'd suggest adding an adjustable fuel pressure regulator to that list, if you're going to keep stock injectors. Here in the states they're $120 or so for a Nismo, thats what I have and I like it.

Good luck

- high flow cat for the exhaust $180-$400 depending on how high flowing you want it to be

- RB25 turbo (high flow) $1500-$2000 depending on who you get to highflow it

- Trust intercooler $......?

- Bosch 910 Fuel pump $250 (going by what 044's and 040's are worth)

- Electronic boost controller $375 for a Greddy Profec B

- ECU remap $150 PM CEF11E about it or you could pay up to $1000 for a workshop to do it

If you're going to be getting a highflow turbo you're going to want to get bigger injectors too

And probably new coilpacks coz the std ones would probably be dying

15-16psi would be fine

And yeh whatever your budget, add at least another half of it on top for other things that will come up and need replacing.

My injectors maxed out at 194rwkw, this is @ 15 psi.

What the shit. $2000 for the turbo.. Is this like top of the line?

How good of a turbo could I get for $1000. I'd want it to be steel wheel/highflowed still.

$1000? 2nd hand aftermarket item or highflow.

My GT35R cost me $1600 new. I'm sure you could get a GT2530 or something for a similar price and still be reasonably bolt on.

If you want a cheap upgrade then a standard RB25 turbo for $3-400 but you won't be able to run much boost or make much power. Will certainly be better than the stock 20 turbo though.

- high flow cat for the exhaust - $300

- RB25 turbo (high flow) - hi flow cost about $2K as suggested for a ball bearing hiflow turbo.. just get HYPERGEAR turbo is about $900 from the for sale by trader section of these forums.

- Trust intercooler - probably too expensive.. get a cheap kit like GKTECK for about $400 for the kit.

- Bosch 910 Fuel pump - $250

- Electronic boost controller - Just get a manual turbotech boost controller for $40.. set it to highest you want to run. to use lower boost, use your right foot less

- ECU remap - $150 from user on these forums called CEFFIE.

that is the only way you will come close to $2K.

you're version of event will be closer to $4k just for parts.

Okay I like your list better ... but what would you boost that to?? ..

have a read.

the same user/company is on these forums as HYPERGEAR

ask him questions regarding choice of turbo and boost to use.

his site has vids and dyno sheets and mods etc..

However, keep in mind that you will run out of injectors before you reach the max power these turbo's can provide.

perhaps search this forum for GTR+INJECTORS+RB20 to see a guide on how to use the GTR injectors and resistor on the RB20, then look at buying them too.
