I own the Nurburgring Edition of the VXR. And after watching this video I noticed that the vac pipes are in the wrong location which would cause the lag.
On the turbo there's the boost solenoid with 3 vac pipes that connect to it.
The one on bottom left goes to the back of the turbo. You had it going to the Recirculating valve which is wrong! And the vac pipe that was connected on the bottom left of the boost solenoid should be connected to the Recirculating valve.
The one on the top goes to the actuator which was correct.
And the one on the bottom right goes to the turbo manifold which was correct.
Hope this helps
Hi Josh, This car has been seen by the garage that sold him the car on two occasions and a Vauxhall technician on a couple of occasions so we took it that all hoses were in their correct location. I studied what you said against other Google images and have to agree, what you say looks to be correct. I'll check this out tomorrow and update. Thanks for the info.
Cheers
Martin
If you swap them into there correct location it'll boost how it should again.
Just done it Josh, works a treat now. I have done a part 2 vid to this and it will be up later.
Well spotted bud.
Cheers
Martin
Glad to help! And pleased this fixed the boost issue. Bet she goes better now

I don't know how u haven't got more subscribers? Always informative and I genuinely nice guy/family
No one shares my vids, That's why Stew.
Cheers
Martin
That's one well loved car Martin. Looks like Gary spends a fair bit of time keeping that engine bay sparkling!
Big boys and their toys John lol
It's funny really, yours are the only vids where I haven't got the same car, but still really enjoy watching them! Good work again chap 👍
Thanks bud. Glad you enjoy them.
Cheers
Martin
Hi Martin, Gary should have brought it to you in the first place, would have saved a bit of money, One of the things i like about you is that you are not afraid to tackle anything. Great video, looking forward to the next one.
TBH Dave, Gary found the info after putting it in the hands of the garage who sold him the car with no joy, I just put it together in a vid for everyone.
Cheers
Martin
Great video Martin, i'm sure it helps lots of people with this same problem which can be very frustrating when they can't find the fault.
Cheers, Jeff.
Yes Jeff, Many people with a lag problem but not much out there on this upgrade.
Good video Martin,problem fixed.
I had the same problem with the lag in 6th gear it would surge on and off with power. I put a larger diameter exhaust on, not had the same problem since.
Nice one mate , love my Halfords 1/4 drive set too , also love how the Astra vxr has monster torque steer . Keep it up
The Halfords professional stuff is great for the money and yes, monster torque steer on full chat lol
nice one m8 another problem fixed. great video.
Nice work Martin. Turbo cars are always a so harder to work on since you got such little space to work in! I have the same problem with my 2.0t.
Yes, things are very tight in modern cars, give me an older car to work on anyday lol
Hi mate great video not a lot of room in there a handy tool you can get is a hand vacuum pump you can put vacuum on the valve and you can read live data to see if the Reading change the tool is inexpensive but can be used for lots of things on your engine
i have thought about one of those Leon but not got round to getting one yet as these are not my cars.
If you ever get that turbo chatter at higher revs like yours is doing, something still not right, Id always be looking at the recirc valve (which you changed), boost sensor pipes on turbo correct and also rear boost sensor under inlet as the pipe which controls the oe dump valve popped off most of the time.
It's running fine now. The pipes were crossed but once we changed them Everything is now fine.
Great stuff.
Another good video and fault cure. Only 25 quid? A Bargain, I just spent $300 on a strut replacement. Betcha that Astra goes like stink!
It's really quick Bri. $300, It does pay to DIY lol
great vid Martin enjoyed mate. cheers Steve. ps off on my hols tomorrow for a week i'll look forward to your vids when i get back keep them coming...
Have a good un bud.
Cheers
Martin
I took the whole turbo/manifold out to change mine haha spent hours trying to fit my hands in with an allen key with the turbo on
You know then Jayden, a right pain but it's the same with all modern cars I think.
Very good guide to a common problem on these
Thanks Andy, I take it you have a VXR by your TH-cam name.
retrorestore used to have a astra for 3 years recently sold it due to work commitments miss it
Great share Martin . Those tend to be a problem ! Thumbs up man..
It's a common thing Shawn as you said.
Cheers
Martin
Nice result Mart, Gary will be chuffed.
Baz.
Yes he is Baz.
Cheers
Martin
No video for a week, then two come along at once. Did you use to be a bus driver haha. Good job Martin. All the best .rob.
Haha, Rob, Had family time last week but back on it now lol
Great vid Martin. Common problem on the Vxr you are best using the up rated spring they are great cars my brother has £15k+ in his Vxr running stage 3.5 with ko6 Hybrid Turbo ,6 pot brakes on front and vectra vxr brake conversion on the back
Cheers
Jamie
I'll tell Gary that Jamie. Very quick when they come on song.
Cheers
Martin
I will Email you some pictures of the car Martin
Cheers
Jamie
did the same on an sri turbo version a few years ago martin tighter than a nuns... im sure we did it from the underside when re assembleing for more room. PS your driveway looks really difrent and i cant put my finger on why/whats missing 😂
Haha, the Transit van is further back Harry.
Under the hood of that car reminds me of my old Saab 9000 CSE Turbo
hi on my vxr im getting turkey noise when i boost and let off is mine same problem ?
nice one martin goood video as allways
Thanks Chris
Hey MARTIN,Alistair here from SOUTH Africa, I have a problem with o my opc h now for almost 8 months,replaced the turbo core as the car was smoking but had the issue of boost before that, swopped over coilpack and boost control solinoid, issue still remains,when I accelerate my car through gears normally car is OK but the moment accelerate hard from 1st right through to 6th gear I get interference with boost as if the car is struggling to build up boost, what might the issue be.
Don't know, You might want to plug in a diagnostic reader to see if there are any codes.
good job 👍
Top video mate I share on Twitter everytime I thumbs up
Nice one Steve.
Cheers
Martin
What size are Allen screws? 8mm?
Good vid lads keep it up
Cheers Peter.
Good old leh engine
His new part not very good mate he should of got the forge 1 ( I had same problem)
If he still gets the problem tell him to get the blue spring as that will be better for the vxr
Thanks for the info Micheal, i'll let him know.
Cheers
Martin
Has he considered doing an airbox swap from a 1.9cdti to get more air into the engine too?
I'll let him know that.
Cheers
Martin
Hay ho matey. Like the new intro. :-)
Cheers Austin, like the new steering wheel as well lol
Delete that cross over pipe. That removes alot of flat spots throughout the rev range. Courtenay sport do a direct hose from the turbo to the air filter
which pipe would that be?
@@juanburger1267 it's the pipe that goes over the top of the head. He removes it in the video. You can buy a cross over delete or use the air box off the diesel turbo
Are u the same guy who use to have a channel printing t shirts etc?
Yes I am.
hi there what would be the cause to have more response of half throttle than full throttle when i put my foot down its like if it dont go no were ?
get it on a diagnostic meter bud. that should throw some light on it.
@@retrorestore thank you so much will get it on obd reader on the weekend
If I get a new turbo , does that mean the recirc valve on it is new ?
Don't know, sorry.
Just shared your video on FB, Martin...Hope this helps... :-)
Thanks Malcolm, Regards
Martin
That boost control solenoid is set up wrong. Vac line for the recirc should come from the inlet, nothing to do with the actuator. Ive built these engines over 600 hp
Sorted now bud.
Cheers
Martin
I own a twintop cosmo version.
Nice job gents . Looked a pig to fix mind.
Cheers Pete.
I haven't been subbed long to be honest but great vids mate and if he still getting the same thing down the line tel him I no what the problem is it's a Vauxhall 💩
Haha, Sounds about right lol
