GRB Tune up help AUCKLAND AREA

[bboyshing0]

Hey guys.

I've just recently bought myself a JDM 2.0L GRB STi 2008.

I want to try make 240kw out of this like my previous GDB (This one was moderately modified such as FMIC, Injectors, Full Exhaust, Fuel Pump, rebuilt VF22 (as it blew up lol))

However I want to keep the engine layout close to factory as possible.

Only mods ill do is custom full exhaust, Boost Controller, and a BOV is this really not enough for 240kw? Because I am sure I heard a few people were able to gain at least close to 240kw with factory top mount etc etc.

Any recommended Tuners out there in Auckland as well who specialises in Subaru ?? Because my main tuner GCP isn't very good with communication, + his dyno is broken or something he last told me in April 2015

Thanks <3

You would probably want to include an upgraded air intake - either a free-er flowing standard filter, or a full cold air intake.

Also do the Fuel pump as well, quite important if you want to increase the boost. Injectors also doesn't change the engine layout at all, and can help with overhead, making sure they don't over-work themselves. TMIC should be okay for that level of power on the street.

The TMIC on them is pretty big and would probbbbably handle that kind of power level.

I don't think a VF turbo (without modification) will make that power on a truthful dyno.

Erm... the grbs run 225kw factory, 305hp

Gentle tickle with the fueling and a few extra psi boost via factory ecu and 240kw should be easy. Dont bother with an ebc, the factory ecu can control a 3 port solenoid with better control and response than a sub $1k ebc can give

My grb is making an estimated 240kw at the flywheel with a gentle tickle, should catch up sometime and show you what a gentle tune can do for yah

225fwkw maybe not 225wkw.

Correct. Factory rating 305bhp or 308ps, works out at about 225kw at the flywheel. I need to do some more logging to work out what kinda wheel kw's i'm putting out

Best mods for v7- is decent turbo, injectors, exhaust, fuel pump and tune. Let the damn thing breathe vfs are so limiting.

Get that thing on a dyno kiwi fozze..Probably 190-200 at the wheels ..

I intend to, the roadtest dyno i have is pretty damn close to the torque dyno, but i'm pretty skint atm. Sooo, i'm going to keep tinkering with the tune then late this year early next i'm hoping to get it on the dyno.

Hey thanks Ill upgrade my fuel pump and injectors as well thank you for the tip ^~^

[Guest]

If fuel injectors are pinks they will max just after turbo peaks out so should be fine as is.

Hey thanks, yeah I was confused yesterday because I saw a post where a guy tuned his GRB with a full exhaust and only managed to get 194kw ATW and in my head i was like that can't be right ?? but then it was ATW lol so missed out that part.

Any Recommened tuners in Auckland btw ?
