Hello OpelAus... Holden Astra 03 Sri Turbo

[Moejlh]

Hi everyone my name is Moe and i have just joined this forum i purchased a Astra turbo off (GRJ355) a couple of weeks ago and its a great car goes very well an is great on petrol.

I have afew mods that a planned for the car in the next upcoming months including a fuel pump and a re-tune of the uni chip computer.

This is the 1st Holden i have owned and im very happy with it i recently had a Ford xr6 turbo with 440hp at the wheels on 9psi and a Wrx so i was after something different.

Anyways i just wanted to introduce myself im up for meet ups or cruises and also if anyone no's of any good tuning places that would help.
Thanks

[AfterBurner]

Gday mate & welcome...

Was wondering where it dissappeared to from CarSales.com...

[chrissn89]

Welcome, well the astra is a nice change coming from the xr6t and WRX just one comment if your planning on doing a few more performance mods hopefully the front wheel drive doesn't let you down. Good tyres and an LSD help alot.

[Moejlh]

Thanks for the welcome people...

And im getting the turbo for the car re-built next week as it has a small oil leak...
Also where can i find a Lsd for the car an how much a they worth?!

[CNBLU]

Is it the standard turbo or a VXR turbo that you are getting re-built?

You can get a brand new VXR turbo for around $800 delivered these days

Hi its the standard turbo from what i know... where can i find the vxr turbo at and does it bolt straight up from the standard turbo?

[PaulyJ]

Brand new VXR turbo you can get from Courtney in the UK. There are links somewhere on this site.
And yes it bolts straight up.
There's plenty of info on here for you to go through, especially for your turbs.
All the best

+1 for the VXR turbo btw. Grab it from Courtenay or Autovaux

[Moejlh]

Thanks guys for the welcomes..

I have just emailed Courtenay sports and hoping to hear from them soon about ordering a new turbo.

[Moejlh]

Hey guys just an update i just got off the phone to Courtenay sports and just ordered a new vxr turbo with fitting kit and new gaskets so hopefully my car will be back on the road by late next week fingers crossed!...

Good job! Are you gonna be fitting the turbo yourself?

[Moejlh]

Thank you. And nah my mechanic is fitting it for me his really good with turbos, I would do it myself but just worried i would stuff something up...

[03srit]

Same here I've got my turbo sitting in my room.. I might get a mechanic to fit just to be on the safe side..

[Moejlh]

Yay finally got my car back the other day its running great...

Just feels like the car in 2nd and 3r is holding back abit. Would a re-tune of the uni-chip computer fix this problem?

[AfterBurner]

Did u also get the smaller Banjo bolt? Otherwise known as the 'oil restrictor bolt'??

You may need a re-tune considering the turbo has slightly different characteristics...

Can you elaborate a little..?

Hi yes i did get the Banjo Bolt. And yeh i think i might end up retuning the car.

If im in 2nd or 3rd gear and put my foot flat down on the pedal is sorta lags from about 2500rpm until about 4000 rpm then starts boosting and goes great.

[SSS_Hoon]

could the lag be due to the vxr turbo having a larger rear wheel? does it have a larger exhaust wheel if so how much larger?

i know going from my T25 with a .64 rear almost no lag at all to my T28 with the .86 rear with a fair bit of lag, but once it starts to boost it hits hard.

Hi Everyone, I have just joined up to this site and have never used a Forum before so please be patient with me :-)

I just purchased a Astra 2003 Sri turbo z20let and have smoke issues.

1. Its Blue smoke
2. The exhaust tip is very black
3. The intercooler side of the turbo had a spoon full of oil in it but it has ben cleaned and not returned, Could the exhaust seal have just gone as I havnt check that side of it.
4. Could it be oil rings, Compression test is all around 175
5. Now I was thinking, Could it be the Valve stem seals?
6. The top of all the pistons are black , Also all the spark plugs are very black and a little oily aswell
7. The car seems to run and idle very well
8. engine stays very cool, Never gets close to overheating.

if anyone could help me please.
