Well started doing it the drive home after I picked it up... Few times when I stopped at lights it'd just cut out so I'd have to restart it. Doesn't do it every time but idles a bit funny too like it's threatening to do it. Did it 4 times yesterday when I drove home

Also when I was driving to a friend's place I started losing boost/power and could hear a hissing noise... At the friend's place, I checked under the bonnet to see if I could work out wtf was going on. Found that a clamp was loose on the big air intake pipe on the right hand side (the one with twin turbo written on it) and the rubber hosey part coming off it was slipped down. Fixed that and tightened it and seemed to fix the probs breifly but happened again when driving home.

Checked the same spot and this time it looked fine... Getting it all checked by Autotech tomorrow to be safe and I haven't really driven it much since cause it's pretty embarrassing!!! Looks like I'm stalling all the time

You know I'll hurt you

haha nah you were a easy one...in swap over out...

its people who dont believe a kettle would ever break and get nice n angry...argh.

or those who buy a 100 dollar evap cooler, get cut when it doesn't cool down a lounge room and want it swapped 3 weeks later.

what size cams are in it? do you have adjustable cams gears? have the centres been tightened?

[GTRKat]

264 in, 272 ex, yes and I haven't checked but will have Ed check tomorrow.

They were perfect from Tuesday until when I picked the car up on Friday afternoon.

[GTRKat]

I should add that I know it's quite possible that I have more than one problem here. Could be any number of things as to why its cutting out.

Air hissing and already 1 loose hose found likely to be caused by the person playing around in that area on Friday.

[GTRKat]

Turns out the other part of the hose that I had tightened was loose also but was not plainly obvious to see. All fixed! And yes was the autoelectrical dude's fault!

hi gtrkat, i have been following you're progress so far and u have all the goods motor wise. and with any build the headaches and dramas arrise when everything is put together and you're driving it for the first time.

from you're last post with the looose hose/pipe/clamp ' air-hissing' noise and it stalling, i'm sure u'd have to change you're spark plugs as they would be fouled by now, so factor that in when you go to talk to the electrician, and get him to re-emburse you for them.

just my 2 cents. good luck with the car, and hope to see it on the road soon, problem free

[GTRKat]

Hey Matey cheers for that. It was only driven a tiny amount before getting fixed. I'll get onto the guys at Autotech and get them to check it but it doesn't feel like they've been affected by this at all - I can tell you he will be paying for them if there's an issue though considering they're brand new!

Not yet but Greg is going to snap some for me before it goes

Autotech are also going to take some of it all fully assembled before it gets dropped back in.

I was just reading through and noticed there were no pics of the head so I attached some below. Someone asked what the weight differences of the pistons were, lightest was 366.9, heaviest 368.3, the pins were within .1g. Matching them up with the lightest piston on the heaviest rod small end I had to remove a max of .7 grams from some rods. The crank was balanced as well. The crank balance from Tomei is very good but you can get it a touch better. The kit fitted with no mods to the block or pistons. Overall the 2.8 is a really nice kit.

Kat, I saw the dyno graph from the initial tune the other day, very nice torque curve! Will be nice to see once everything is sorted completely.

Some pics of the head:

Cheers,

Greg.

how is yours going now Steve-O? what kind of response are the GT-RS's giving with the 30?

Mate its on the run in tune (got 400 more k's to go, ill do them quite fast) then swap ECU's and go for some decent boost. Its just the best combo on the big bottom end, wish i did it sooner and didnt waste time with the 2.6 block

Basically its got the response of the poxy little stock twins but way, WAY more torque and once the boost is there the power aswel.

[GTRKat]

Hey Greg cheers for that! I'm so happy with the car, words can't even describe!! Torque curve is great, its just such a different car now! (Should add that more pics are on facebook and my photobucket of the whole process)

Run in tune is done but still not doing anything terribly nasty to her just yet. Few things need to go still, in the not too distant future I'll be getting a metal cat and choosing another exhaust as mine both aren't up to scratch anymore. Will also have a new front mount but not sure when... Kinda letting our finances settle after such a large amount of work and Christmas all at once!

Much nicer to use setup than when you had the GT47 on there then?
