Next Setup For My R33 Gtr

[andy95'R33GTR]

im wondering what is the next setup for my R33 GTR

here's my setup so far

i have APEXI AVCR boost controller...boost reaches 1.5 bar, lowering the boost after a interooler pipe remove the other night

stock garrett twin turbos with ball bearings (i think)

APEXI SAFC

TWIN HKS SSQ BOV

BLITZ Exhaust

APEXI POWER intake

stock ecu

(I haven't opened my engine and check the cams...and inner parts, i haven't added performance parts yet, this is what iv gotten when i bought the car from japan) with the HKS BOV, what could be the limit of the boost of this setup???thnx

[NYTSKY]

I wouldnt go any higher than that.The next thing would be to get a programmable ECU of some sort.And a decent clutch.

[andy95'R33GTR]

what programmable ecu? and what kind of decent clutch??im confused of many stages of clutch....what do you recommend??thnx

[NYTSKY]

Power FC if you can get one.I think ive seen a few for sale in the for sale section.

Haltech are good but a bit expensive.

As for clutches a good upgrade is a ceramic cushion button.Can handle up to 300ish kw and are good for daily driving.

I have given mine a bit of a caining, a few passes down the quarter.Still feels like it did when it was new.

1.5 bar boost and stock turbos ???? I wonder how long she is going to last. If I was you, I would back off the boost to under 1 bar until you replace the turbos .

Stock R33 GTR turbos are not ball bearing .

[N1GTR]

^^^What he said

Get the boost back down to 1bar for now

Then buy a new ECU and a set of -5's, then you can go back to 1.5bar

[Omurru]

Yep next thing i'd be doing would be a computer and a tune, most people round here use PowerFC's and regardless of what people tell you APEXI do still make them and they are readily available for the Rb26.

Also if you are unsure of what turbos you've got best to keep them under 1bar for the time being, as the others have said...

[andy95'R33GTR]

i haven't touch the settings oh my avcr, the whole setup is from japan, it reaches to 1.4 and 1.5 bar from my avcr, could it be possible that the cause of high boost is because i removed the muffler? i only left the resonator?? i already checked my turbos, its a GARRETT M24 A/R42 , i tried to spin it with my fingers and it stops about 2 to 3 secs...so maybe its a ball bearings? were can i find the power fc ecu? and how much?

So, because your car already appeared to be running '1.4-1.5 bar' when it arrived from Japan you assumed it was safe to continue doing so?

Im surprised your turbos haven't combusted and lunched your motor

Im with Blitz... VERY risky running 1.5bar.

Just asking for a 10k+ rebuild

Just out of curiosity, when a turbo blows itself to bits like your suggesting this one could, what would "lunch" the motor?

Is it possible for the turbo particles to get through the intercooler? It doesnt look like theres alot of room for bits to get through!

(i dont know a great deal about turbos blowing up.. thought this might be a good place to ask )

Search is your friend but ....... when a RB26 ceramic exhaust wheel turbo goes it is generally spinning fast enought that it sends ceramic bits everywhere including back down the exhaust manifold and potentially into the engine through an open exhaust valve - hence everyone's warnings. The stock turbo's are known for doing this with increased boost and age.

Well, if you're going to keep it at 1.5bar please let us know how long they last for future reference

[wrxhoon]

If you do a search you will find pics of the pistons from an RB 26 that the rear turbo let go in one of my ex cars a few years ago .

[andy95'R33GTR]

i think i tried turning of my avcr before...but the psi is still thesame....could my wastegate stock up????

Take your car to a good GTR workshop and get them to give you advice and do the work, or your going to end up with a very big repair bill.

[andy95'R33GTR]

thats why im asking you guys,, there is no good shop here for GTR's, don't even have a dyno here,, its philippines, and in the south of the pphilippines....=(
