300rwkw club please read I need you're help!!!!

The car felt a little stronger with less boost.

what plugs/gap are you using?

Also does the haltech pull set amounts of timing out when certain knock levels are reached?

[B-Man]

A dyno graph with power, revs, boost and AFRs will reveal your problem.

Sumthing is not right - that's for sure.

[cameron]

what type of T piece boost controller is it ? a red turbosmart one ?

try turning boost down to 12psi and take it for a strap.

[Skyrine-Dave]

what size AR is on the GT30? .63/.82/1.06?

[RNS11Z]

Hey mate i remember you, i told you to see matty for tuning as you told me you had problems.

On matty's dyno i made 340rwhwp yet on the weekend the car made 420rwhp with the same set up except blown manifold gasket and has gone almost 121mph with 4psi less boost of what it was tuned on.

I would say it could be your mechanics have either done something to your car or matty isnt tuning it right.

As much as you are sick of spending money, your going to have to spend more as there arent many profesional skyline tuners/ builders here in qld

if you want pm your contact details and il give you a call

with a conversion i would also be looking for all air leaks first...everywhere intercololer pipes vacuum lines everything

check fuel filter

then look at cam timing if adjusted take back to stock then go from there on a dyno.

then check plugs and gap.

set timing to 20 deg adv at 1200rpm

remove exhaust leave just the dump

on the dyno check air fuel ration should be around 12- 12.5 to 1 for a good tune

run something a little better than a t piece but it doesnt have to be electronic just something a bit better..

check regulator pressure make sure it is aroun 35-40psi at idle

the halteck is a map sesor have you totally rewired or bought a plug in harness for it

check your map senso is a 3 bar item

check you are getting wot

some of these are drawing at straws and considering you have made strong power at lower level it leads me to believe there are two problems ignition or fueling....

check coil packs, check regulator and read you ignition maps on higher boost thats what a halteck is good for look at them on the pc...

hope this helps!!

Hey guys, thanks for you're responses. I have a heaps of things that need to be addressed by the sounds of things. Last night i was thinking about just ripping the halteck out and starting again. I will get photo's of the stuff you have asked for as I couldn't find an AR no. I am one of those guys that just say's I want to go fast, how much? fingers crossed they do the right thing.

Looks like a 1.06 rear from the photo?

[Guest INASNT]

Looks like a 1.06 rear from the photo?

na more like 0.86. Those pics make it hard to tell.

[Fitzpatrick Speed Works]

irs not important as it is still pushing 22psi, which ever way you look at it 22psi is 22psi, only the characteristics of boost delevier and response will be affected by the ar no. on the turbo...

eg... 1.06 on my gtr came in a 5800

.86 comes in a 4800

on the same bosst it stil makes the same figures..

the problem is not the haltech they are fantastic computers, they just need someone that knows about haltechs to work on them.... i recomend you call this bloke

www.justenginemanagement.com

he knows about them more tha anyone he used to make them before starting his own business...

[tribex]

dont know if this helps but we went from 229 rwkw's to 257 just by gettin someone with clues and time to retune microtech on gtr, which also rely on map sensor....aftermarket ecu's can be a real bastard....

[RNS11Z]

It looks more like a 1.0* rear housing. My gt30's rear housing was a .82 and it was way smaller. it seems some were along the line there is a fault with the conversion.

Who have you taken it to so far?

[PHaT MR30]

yeh boost controller can have somethingto do with it, not too likely.. but a mate had a turbosmart dualstage and its was just plain shit removed it and was 10 times better.

get a profec b or something similar ive have one and its seriously a good thing and fairly cheap

[RNS11Z]

Matty,

just spoke with Goran. I told him about your situation, he said to give him a call on 3299 4344 and book it in with him. He said it could be a couple of things but i'l let you speak to him.

Good luck with it.

profec b's r shit with external gate. HKS EVC are the best cause they use a stepper motor

[RNS11Z]

I used the blitz dual sbc worked fine.... can control when full boost comes on and so on. I thought it was excellent.
