New Setup

[gun32gtr]

im using profec B

good??? how much??

[frankxinyu]

they are cheap. but i dont have any problem with it at all....

i believe they are around 400.

[gun32gtr]

$400 seems like a good price.. apexi avc-r is $700 but they seem really good... but if u reckon the cheaper one is ok might look into that

Don;t use a single solenoid controller if you want to go to 1.2 bar or above.

I would recommend a Blitz unit. Take you pick which of the dual solenoid version you prefer. I got an ID III

oh ok makes mit easier to hold boost etc,plus you can run high low boost is that right???

just make sure you match your wastegate spring to suit the higher boost, that way your controller wont be working as hard to bleed off.

I've got a similar setup to what gun32gtr wants to do to his car.

Garrett 2860r(-5), Dump pipes, Exhaust, EBC, PFC, Splitfire coils, Jim Berry Clutch on a standard unopened motor showing 105xxxkm's.

All that made 275awkw at 18psi.

I'm by no means the worlds best driver and i still managed an 11.72 @ 118mph on my 4th pass on shitty bald street tyres.

I think that the mods you've got listed are fine and your car should be capable of 11's comfortably. I'd definately go with the 2860r's. They spool at around 2800rpm and hit full boost by about 4500rpm.

I hope all goes well for you.

MARKK hows it going? likie to no how ur car drives etc mate aS ive never been in anything other than my stock gtr... so boost starts at 2800 then is like BANG full boost or does it ease on? ill also be getting some cams/gears aswel, do u have cams at? also where did u purchase the gt2860s from?

ive seen them on ebay are they the real deal do u no? 3k i think they are!

agreed

the AVC-R wont cut it.

You need a dual for sure. send a PM to ferni. I cant remember what EBC he ended up with, but he had to change as he had issues

im doing my turbos soon as well, and i have GT2860-5s in mind. i was told they are quite responsive, yet still bigger than the GTSS. can anyone tell me when their 2860s (2530s) spoll up in the stock 2.6l engine?

Also the -5... bigger than GT-SS... are they are same as 2530's essentially???

I get confused between the "-5 & -7"

thanks mate i pm later,

yeh the -5 ill go there similair to 2530 should be fun then????

It is important to set the RPM limiter at say 7700....so you don't.

320Awkws with a t04z?What power rating is the turbo?

gun32gtr,

The other thing is that with the gt-ss turbo's your 1/4 mile figures will be( with your mods )around,

12.5 seconds on street tyres and 12's with stickys.

I am searching for 12's with road tyres and 11.5's with stickys and thats why I picked the 2530's.

Dont pay to mush attention to awkws and rwkws,....look at the times people have posted up

then look at the power levels they are producing .(most of the time they are inconsistent.)

It is also wise to see the modifications they have completed and what tune and boost they normally run.

Cheers and good luck with the upgrade.

8 grand is fine. the idea is to not rev it past that. and not rely on a oil pump destroying rev limiter. oh its a "800hp" item.

11.7@ 116mph and boost is 1.2 bar.

[T04GTR]

if you ont mind running 1.5bar+ go twins to get the power.

I've only got standard cams/cam gears. I did a comp test before the dyno (about 6 months ago). All cylinders around the 155 mark. I just did another comp just the other week. All cylinders still the same, just cylinder 6 was down at 150, but that could be due to a number of reasons.

The car feels really strong with heaps of torque.

Boost eases on between 2800 and 4000, then after that BANG. I've actually just upgraded injectors, pump and reg. Should hopefully come back with some more power after the dyno.

I got my 2860r's from rotomaster in Melbourne. I think i paid around the $1200 mark each.

One of the traders on here is selling them for $1300 each. (CRD i think it was).

Cheers

[frankxinyu]

shit....does anyone know what kind of boost the profec B can hold up to?? it says 3 bar.....

thats the only ebc GReddy offers.....so i have to used another item if that doesnt work out.....

[gun32gtr]

to4gtr- ok so 8grand is ok if nu dont bounce of it all the time?

markk- sounds like what im after should be alot of fun(cant wait)ill give crd a ring thNKS

[Roy]

Yeh, AVCR are real bad...i will give someone $400 for theirs so they can get a Blitz etc. (Seriously)

Its how you set them up...try 8psi spring and running 1.2bar with no probs thru the AVCR...you just have to read the manual...but if your not happy i need a new one

[rob82]

I've tuned a GTR with 2860R-5 cams and all the fruit make 460hp on about 23psi of boost before running out of fuel pump. They come with a piss weak wastegate spring on them from memory and I was having trouble controlling boost pressure with an AVCR. Have seen alot of aftermarket boost controller struggle to hold boost at around 3 times the wastegate pressure and below.

I would definately get larger wastegates say 15psi and I would definately get the bosch 044 as there flow rates dont drop as heavily as the pressure goes up compared to alot of the jap stuff.

I would be more inclined to stay with the standard oil pump as well and try your hardest not to bouce the revlimiter as thats what breaks oil pump drives especially brittle N1 drives. If need be raise your rev limiter a couple hundred rpm if it save hitting the revlimiter.

[gun32gtr]

so if u raise the limiter say 8300 then 8000 wont be the limiter and it wont bounce causing the oil pump to break. is that it? i want a fairly safe tune as i want the motor to last a few more yrs if i can...

[gun32gtr]

its begun

[gun32gtr]

when i get cams should i get new valve springs? as ill be putting new stem seals in as mine leak abit
