I've been following this series with massive interest. Your knowledge and attention to detail is incredible. I had one of these from 2005 until 2008 when it got written off on a wet day by a 1.3 Escort on bald tyres. It was my first performance car and I've got lots of fond memories of it. I'd been in a Cossvaux tuned one a year or so before I bought mine and from that day on I had to have one. I replaced it with a H VXR and a few years later replaced that with a J VXR but they never quite had the same feel. I miss the SRi Turbo like you wouldn't believe even to this day. Thank you for the trip down memory lane 👌
What a wealth of information this has got to be the best channel on youtube for anyone into cars and engine building great stuff top job Aaron keep em coming all the best mate
Got one in my back yard atm , very rare down under mate. I couldn't appreciate lil bits and pieces on these sweethearts that I've pick up from you more.
Don't really see these engines worked over here in Australia it's interesting to see all the work your doing. Awesome channel mate you have a ton of knowledge just subbed last night 👍.
I drove a heavily built one of these a good few years back and it was just a struggle to keep the power on the road. Cracking video Aaron engine sounds fab
Top video once again🙏 engine sounds perfect,silky smooth and so rev happy and responsive👍 I love a zlet with a miltek on sounds amazing I have one on my sri-t. Love all this zlet content lately and can not wait for the driving video's of this car,great work👌👍
decated my black edition corsa d and did the same left everything lose and was a peice of cake and it made a huge diff to the power u felt it pick up quicker the cat really does hold that ecotecs back
love the chopped up ranting! aarons got lots of fair points though. i couldnt remember how it sounded before was this vid catching injector ticking or tappets? love aarons work. got a horrible feeling im gonna end up taking him astras & cash if i keep going on ebay
Love the MK4 Astras. I've had 3 Astras so far, a MK4 1.6, Mk5 1.9 and a Mk6 1.6T gtc. I hope to own a gsi/Sri T one day, hopefully very soon. There's just something about them that you just can't put your finger on...
Your probably right about the engins.i dont now how the engines where brock in.onley 1 of them i seen brock in.but the engine was siting for a long time b4 it was fitted in.i go for saab engines cos iv had 4 saab and the engines were allway good.the gearboxes were crap tho.i broke 2 of them.f23 box is much beter than the saab fm55.thanks for being decent and geting me right about thes engines.
I love a mk4 GSi, and your knowledge of them is awesome. What paint do you use for the aluminium parts? I've been using Simoniz engine enamel but looks really fake compared to yours. Looking forward to the next one.
Is this going to be for sale in the near future? Just got rid of my arden GSi after nearly 3 years of owning it and regret it alot now... Loved embarrassing financed spice boys
To me that sound at idle means you've nailed the set up and mapping, so quiet I could hear the injectors snapping But once revving up it still sounds unobnoxious, the neighbours would be happy anyway Push it on a motorway and it's as loud as any speed freak would like!
I have a 1.8 SRi i’ve had the car for eight years parents brought it for me because my other car while it died parked it in the mother-in-law‘s garage two years ago really want to get it back on the road just haven’t got time
Hi I wanna to ask you about the v band diameter inner and outer because I will fabricate one stainless steel 304 so if you pls to give me the diameters ...thanks bro
I got one 3 inch 76mm it is a small one and get 4 inch one it is a big one and I measure the outer turbine I got 99.41 mm I remember so what is the right solution ? Pls advice thanks alot
Most engine failures are deu to build and service problems, i have heard numerous times people blow op engines amd there always like, shitty engine, but they expect it to make 600hp while juist doing normal service intervals and drive them like shit
Had to laugh at the short story of people and how they blaim the engine and how they're 'crap' and not themselves and the motions they go through of having new cars on fiance with warranty etc then end up full circle again. So true.
cracked me up about the credit golf r n tha 😂😂😂😂
He’s right, it’s a golf r, s3 or fiesta st they all buy lol financed to the hill
Yes you know who you are🤪.....the one's who rev their engine at the traffic lights for the DSG fart🤣.
scottsvxr always had fast Vauxhall’s, I went for a change this year and got a manual cupra 300 on finance lol at least it’s not DSG 😂
@@scottsvxr . I hate that noise.

Pistol Pete I’ve watched a lot of his videos and his knowledge still amazes me

Engine sounds sweet
Definitely sounds it means business!! Top banana.
You are the zlet guru! How’s the red gsi doing?
Clicked on this vid before BoostedBoiz 😁
A mate of mine had one of these, brilliant cars it sounded mint at full blast 👌 what do you think of the new Vxr's ?
I’m proper nerding out to your videos! More JDM content though plz... 😎
Always great vids 👍
Where does the bottom hose on the breather tank go please Aaron?
Are the heads on the MK4 astra still made by cosworth like the old red top calibra's & so on ?
I love a mk4 GSi, and your knowledge of them is awesome. What paint do you use for the aluminium parts? I've been using Simoniz engine enamel but looks really fake compared to yours. Looking forward to the next one.
Awesome video as always. Man I wish you could sort my zaf out! Cheers.
Another great video Aaron can I be cheeky and ask what compound you use in your manifold the engine is really smooth
Amazing , another great video
Awesome video as usually you sure know your Vauxhall’s do you know what would be the best version or OP-COM for a 2008 vec Sri 2.0 Turbo z20net 👍🏻
Is this going to be for sale in the near future? Just got rid of my arden GSi after nearly 3 years of owning it and regret it alot now... Loved embarrassing financed spice boys
To me that sound at idle means you've nailed the set up and mapping, so quiet I could hear the injectors snapping
But once revving up it still sounds unobnoxious, the neighbours would be happy anyway
Push it on a motorway and it's as loud as any speed freak would like!
Do you map cars for people ? Definitely know what your doing ahah got a zafira gsi
As always great videos
Master craftsman
Aaron with what did you clean the gearbox? Product name please
Top advice there.
Hey mate you can actually get a vband gasket. I use them gm aswell.
What’s happening with the Evo? Selling it ??
Dam..your videos make me want to buy a sri/gsi and strip it down and rebuild 😁🙈..keep up the good work/videos dude
What did you clean up your exhaust with ?
I thought someone said they would be going over the top with this build 🤔 lol we all knew you couldn’t help yourself.
I have one of those Opel Astras Bertone with 1.8L petrol engine and really don't know is it possible to upgrade that car or just throw it away...
The OCD is strong with this one........Sounds fantastic
How do you run in your engines?
My crank has started to wobble on idle but pulls straight and true under revvs. Any ideas? Thinking of getting rid if its too expensive. Cheers.
How much would one of this spec cost to buy
What clutch do you recommend for these higher powered z20le* on a F23?
Legend
Subtitles in Spanish pleaseeeee, your content is the best!!!
great video!!!
I have a 1.8 SRi i’ve had the car for eight years parents brought it for me because my other car while it died parked it in the mother-in-law‘s garage two years ago really want to get it back on the road just haven’t got time
Whens more zafira stuff coming 👀
Hello. One stupid question-how to turn on the second water pump,electric one?
It should turn on when you turn ignition on
@@AaronUnknownPerformance Thank you mate,but its seems my one dont work.Will try to find it why.
Shoud plug back in , mine leaked from the top into we're it was magnetic.
Check for corrosion.mm
@@guiiviibygreenman8109 its working mate dont worry.Thanks for advises by the way :)
What spark plugs would you recommend for the Z20LET please bud?
Much more likely to get a reply if you ask him on Instagram . He answers loads more Qs on there as they are easier for him to find
Hi I wanna to ask you about the v band diameter inner and outer because I will fabricate one stainless steel 304 so if you pls to give me the diameters ...thanks bro
I got one 3 inch 76mm it is a small one and get 4 inch one it is a big one and I measure the outer turbine I got 99.41 mm I remember so what is the right solution ? Pls advice thanks alot
You know more about these cars then vauxhall do 😂😂
Great tips! Definitely don't buy cheap lambda's, my emission light stayed on after fitting one and I paid a garage to tell me I bought a shit part lol
Beautiful, Eat your dinner off that engine 🤣💪
Why EDS inlet? Klasen Inlet is so much better for performance.

You are an absolute Guru mate. Love having you as a neighbour. Aron! Can you have a look at my car please? 😂
