This is the Astra J VXR Garrett G series Turbo manifold kit so we've
got all components laid out for this manifold kit.
Probably start with the manifold adapter.
This is a bolt on adaptor for the stock cast manifold now the
difference in the main differences between the Astra J VXR Astra H VXR
in the turbo department is that the Astra H has the turbine housing
built into the manifold, so it's not to remove the turbo or turbine
housing in leave the manifold in place like it is on the Astra J VXR
VXR has its own cast manifold that the turbo faults on two similar to
aftermarket turbo to work the flanges the sticking point the flanges
what's different so that's what we got here.
We've got an adaptor to take us from 4 bolt flange to the Garrett G
Series v-band flange, so it's just a case of you remove the standard
turbo.
Turbine housing and this will just bolt on in place.
So got CNC machined flanges and then a full stainless steel manifold
construction.
They take off for the 45mm turbosmart wastegate, so the stock turbo
setup using internal wastegate and it's a twin-scroll turbo.
This is a single scroll turbo open scroll turbo with an external
wastegate, so that's what some of the extra components in this kit at
4.
It's just too much more and much more controllable way at higher power
of controlling the boost pressure so that's the main reason you would
want to go to an external wastegate it also allows you to package at
11.
So once you attach this to the
Zoe Turner mifold, it's just a case of the band join to the Garrett
g25 turbine housing RG30 turbine housing in the beauty of Yvonne
flange gaskets it offers adjustability we can rotate this and like I
said it's just no gaskets.
We've got a male and female locating ring wants that clamped up in
adjusted in the correct position.
You know the bolts don't rattle loose to blow.
It's much more serviceable in that you can remove it late today and
fit it without any need stuff yet messing around any gaskets or
anything like that video on the g-series turbos will put the links
that in the description and we've also turbosmart 45mm hypergate
external wastegate put another link in the description.
We don't need to go over those again.
We use those in.
Turbo kits now the g-series Range seems to have been the most modern
kind of most advanced turbo at the minute.
So they're the ones were trying to use as much as possible and all the
kids so once we've got that manifold bolted on we got the turbo bolted
on the next thing really is the downpipe so sick welded stainless
steel.
Obviously that was over parts have to mention it because there are
full stainless steel brushed finish.
Obviously, we're trying to build something that looks nice, but
function is obviously more important.
So this is 3 and half inch bore.
Realistically 3 half-inch Boris over cooking it on a g25 550 you
looking at for 150 horsepower.
You don't really need all that ball size, but there's no disadvantage
to having it either you can only benefit from having a larger ball
downpipe.
There's no disadvantage so again.
It's an obvious thing to do it really doesn't start much more to do
that as part of a kit.
So we're always going to use the biggest ball that realistically is
required and it also helps when you do get up and slows higher
horsepower.
Hey guys like with a g30 770 making over 600 horsepower at that point
so to a larger downpipe the wastegate tie in here so with an external
wastegate.
You'll need somewhere for those gases to go when they bypass that
turbine housing.
Play Sky is when it opens up gas can bypass the turbine housing to
maintain the turbine speed overspeeding.
It's not making too much fruit pressure or more boost pressure like
that weighs Gate opens up and we need to get those gas is back out and
into the exhaust system a lot of the time.
You'll see people use creampie creampie.
Xxx work and but we wanted to really try and build a very corgi mplus
kind of solution, so the only real option is to type back into the
downpipe.
It just means absolutely no hassle MOT time they do you know a bit
annoying as Time Goes By you can't turn off a screamer pipe.
So every time you put your foot on the throttle and that way to get
opens up.
Delaying the red range you'll get gas out that scream fight it makes
the car messy.
You know it's illegal so we try wherever possible with these tickets
to stop people into a recirculated downpipe, but yet we've got
flexello in there so
The wastegates really do rattle when they're open and that's usually
wear your see a failure in either the manifold or the downpipe because
here at all so much did the vibrate and that's what cracks the weld
joints or just 42 stainless steel overtime and yeah, you'll then get a
crack form.
It's really important to have this flexible joint in there.
It just give that wastegate somewhere to go and it also AIDS fitment
so it just makes it a little bit easier to fit when you've got a
little bit of room to move things around and at the bottom of the dam
pipe with the standard 3-bolt flange with the bracket on it the boat
it up onto the back of the engine.
So desu ne aftermarket secondary downpipe or secondary decat sectional
sports cat section we've got those we can put the link for that in the
description but also suit the stock secondary section if you need to
put one back in for MOT these cars most of them will pass an MOT with
that secondary without secondary cat sectioning that was what was
really important that we retain the ability to just fit that secondary
catching rather than trying to do a full 3 and a half inch downpipe.
We might have benefited in terms of performance marginally, but the
MOT time when you want them to refit that car and becomes a nightmare
then because you've not got a wee bit so yeah, that's that's one of
the main advantages of kind of keeping that 3-inch bored at the bottom
fully surface flange so it will suit The OC gasket Clamp up nicely.
Obviously, no leaks and no gas blowing out the side so it talks about
all of the exhaust components all the kind of hot parts of the kit so
moving onto the intake side so the Garrett g25 and g30s ng35 or have a
76mm 3-in in take one thing it's really important.
We've gone to some lengths to not compromise on the exhaust side of
things with a 3 and a half inch downpipe, so we can really don't want
to go on the intake side of things and that's why we got this really
tight twisty weird looking hose so
What would be ideal would be a solid intake pipe?
You know from the turbo to the top but given that the clearances
behind the back of the engine.
I really tight and it's really important to us that we maintain that 3
inch bore all the way up with a no more than a 38 centerline radius,
so it's getting a little bit complicated when I talk about centre
landlady said but it means that there's absolutely no reduction in
bore size throughout that bend.
Say it's a kind of like a twisted s bend.
And the whole idea behind that is that we really trying to keep the
airflow nice and smoothly want their phones be really nice and smooth
enters the turbo is pulled in we don't want any restrictions because
of the kinds of we produce our own peace of calling in house and then
cheers performance or make a hose on that calling for us.
So that we can have the effects and we'll have to worry about you know
the hose rubbing on things or if with a major a solid pipe.
It would have been so difficult to Ashley fit it onto the car you more
less to put the intake piping before actually bolting the manifold on
so in terms of serviceability.
It would have been very hard to work on it flares out to 90mm.
Which is the size of the intake pipe do with used some tumours will be
happy with a 90 mm intake pipe.
It really depends on the map of stars some more prefer a smaller one
we can do it, but really would recommend you just stick to the 9th
rather than having an 80 mil like the kind of upgrades ones the stage
1 2 3 upgrades.
And then we got the 25mm recirculation valve port in the top here so
once we've got once you've made that boost pressure and we close the
throttle off.
We need somewhere for that boost pressure to go so the boost pipe will
allow that boost pressure to travel out of the recirculation valve
back into the intake pipe and keep the compressor spinning forget it
all comes down to efficiency so drunk valves a nice.
They make a call noise, but recirculation bulbs inevitable get you
better performance make for a car that drives a lot better.
You know all of the OC manufacturers use recirculation valve on a
turbo Sport 1 even come with the recirculation valve built-in, that's
how.
the kind of turbo manufacturers view them as like an essential item
really so yeah, that's why we've got the ability to just felt that
25mm turbo smart research straight in the side there so at the top of
that Silicone Hose
I got is aluminium intake pipe bracket on it that ties off onto the
brake fluid reservoir that keeps its solid mounted and we've also got
the boss in their overall mass sensor, so you just remove that from
your stock mouth or from your upgraded matter if you've got one and it
just goes straight in there with the stainless steel machine screws
and then the 90mm just popped on the end so an Astra J VXR boost pipe
covers at top of the engine bay, which again is completely opposite
the way the way the Astra H VXR works where the throttle bodies in the
top of the engine bay.
So this is where you'll see the recirculation valve to the turbo
outlet will be here it comes into this silicone reducer animal up to
63 mm into this boost pipe 25mm take off on it for the recirculation
valve that way around and then point off back.
intake
and then shoot off down here to the intercooler now this boost pipe is
a direct fit for an intercooler therefore.
What's the most popular ones for the Astra J obviously you know
European customers.
There are all the options available for those guys, but realistically
we see those in the UK or if we do this very few and far between so we
can't kinda cater for everything.
But probably easiest part of a kit to adapt to whatever kind of set
up.
You've got really so in terms of if there's any part of the modified
to suit something that's other than airtec intercooler is obviously
going to be this part of the kit, but realistically this is also going
to the easiest part of the kids to modify different size clothes like
couples on the end.
Obviously if you've got a rough idea, we can make the shorter or
longer if needed but realistically that's an easy enough piece to
adapt if you don't have an air sac into any just comes onto the oil
and coolant lines, so the oil lines really simple.
We just take the banjo from the back of the Block and then I'm really
nice stainless steel line with a nylon.
PTFE hose, so this is never going to rot away the PTFE hoses, you know
what's the lifetime can still a rubber hose which will degrade with
hot oil overtime this this world Outlast 2 Turbo kit and then just
same again with the coolant lines black now and overbraid these are
rubber lines lines.
If you are more flexible than PCs the lines and these do just carry
coolant, so we don't really need to worry about them.
They kind of the rubber degrading overtime.
This is more than suitable for the warm cool, and it's basically OEM
specs anyway or better than we do now also include a fire sleeve for
all of these lines.
So they feed and then the two coolant lines do include a
Fireproof lining again these come with all the banjos to fit directly
onto although we points and then the an6 fittings to just drop
straight onto the garage is Turbo all of this is fully reversible
there's no part of this kit where you need to kind of coolant lines or
modify anything.
It's all literally just bolt on bolt off stuff kind of eclipse.
We haven't shown here because you know there's not really point in
showing clips and clamps and things like that, but yeah literally
everything you need to install.
This is included in the kit with Ryanair programme filters in the kit
the same thing for phone one if you prefer realistically the old do
the same thing any questions comments or drop us an email all the link
in the bio so that's watching.
