Blitz twin turbo installation

Next remove the idle solenoid control valve connector:-

image

Disconnect the turbo pressure sensor connector. I don't use the stock sensor, even though it is still attached to the intake chamber:-

image

Here's my AEM 3.5 bar MAP sensor, that I'm using instead:-

image

The manual for the UK says to remove the VSV for fuel pressure control, but this doesn't look like a VSV. I think it's the intake temp. sensor, which the UK spec doesn't have (mines a J-spec):-

image

 

Next remove the PCV hose from the VSV valve:-

image

 

I also have my Aeromotive fuel pressure regulator attached to the back of the intake chamber, which I had to remove:-

image

 

Next remove the Water bypass hose from the ISC valve to the no.4 by-pass hose. I found it a lot easier to actually remove the ISC valve from the intake manifold, and then disconnect the hoses there. There's 2 bolts for the ISC valve:-

There's a one way valve to prevent air blowing backwards through the ISC valve. Note the orientation for when you re-install:-

Next remove the EVAP hose from the vacuum pipe on the manifold stay:-

image

And the EVAP hose from the vacuum pipe on the no.4 water bypass pipe to the no.2 vacuum pipe, unfortunatey I didn't get a good pic of it, but it's the hose under the purple connector for my MAP sensor. Also in the pic is the Power steering air hose for the intake chamber, which also needs to be removed:-

image

Next remove the brake booster vacuum hose. There's a couple of copper washers, remove them too:-

image

Next remove the EVAP hose from the charcoal cannister from the no.2 vacuum pipe:-

image

Next remove the no.4 water bypass pipe, there's 2 bolts:-

Next remove the intake manifold stay, there's 1 bolt at the top, and 1 at the bottom. I couldn't get a decent shot of the lower bolt. If you follow the stay down though, it's easiest to get to the lower bolt from under the car:-

image

 

Next remove the electrical wire clamp. This is a bit of a nightmare job, as there isn't lots of room between the end of the manifold and the firewall. If you use a short 12mm socket it will help for the second bolt. I used a 12mm spanner for the first bolt:-

image

image

Next remove the ground wire from the intake manifold, you can just make it out here:-

image

Next remove the bolt from the clamp that holds the diagnostic port:-

image

 

Next remove the 5 bolts and 2 nuts that hold the intake chamber on (There's another 2 bolts that I didn't manage to get pics of, they're right under the manifold, under the no.2 and no.5 runners) :-

With those removed you can remove the intake manifold:-

 

image

image

You should be left with an engine bay that looks like this, remove the gasket for the inlet manifold:-

image

 

Next to remove the injector rail, first of all remove the stock fuel pressure regulator. As I've got an aftermarket one, it was just a case of removing the adaptor:-

image

Next remove all of the injector connectors. You may want to label them, but to be honest they'll pretty much only go on the injector they should go to as the loom points them in the right direction. Also remove the two camshaft position sensors:-

image

Next remove the fuel inlet pipe, place a towel under the union as you undo it to prevent fuel spillage:-

image

 

Remove the 6 bolts and the 3 injector holder plates:-

image

image

 

Next remove the 2 bolts holding the injector rail, the first pic is rubbish, sorry, but the bolt is the one in the middle:-

image

With those two bolts removed the rail should just pull off:-

image

 

Be careful to collect all the injector insulators, here you can see the one on the left was left on the manifold, whilst the one on the right came away with the rail:-

image

 

Here's what the rail looks like removed:-

image

 

You should now be left with something looking like this:-

image

 

That's it for if you're just replacing the injectors. I'll be fitting my new rail and injectors in a couple of weeks time, so I'll post up how to fit them. In the mean while I continued with cleaning up the bits I wanted to remove.

 

To get to the pressure cannistor and the fuel pulsation dampener I decided to remove the inlet manifold runners.

To do this first of all unbolt the pressure cannistor, and remove the two hoses for the VSV, and the two hoses to the actual cannistor, here you can just make out the VSV, there's a bolt either side that you need to undo:-

image

 

With that undone, next undo the 2 bolts holding the wiring loom:-

image

image

 

and the bolt holding the fuel inlet pipe:-

image

 

With that done, it's just a case of undoing the 8 fasteners holding the inlet runner on:-

image

 

And then you can remove the pressure cannistor:-

And you should be left with this:-

image

 

Next to remove the fuel pulsation dampener, I chose to undo the line from the filter to the dampener, as this is going to be replaced anyway:-

image

 

There's 2 bolts holding the fuel pulsation dampener. They were done up real tight:-

image

 

With them undone, you can remove the fuel pulsation dampener:-

image

image

 

And that was pretty much it for today!

Well it was a fantastic day, so I thought I'd do some more work out on the car, although didn't get much done as I kept going inside to get a drink and getting distracted by the racing on the tele.

Anyway, I basically spent some time today starting to tidy up a few odds and sods seeing as hopefully I should have the remaining bits I've been waiting for this week, and will be able to install them the coming weekend.

 

I removed the fuel regulator, which was attached solely by the return hose:-

image

 

image

 

Then I removed the fuel filter, there's the two bolts holding the filter on, the earth cable, and of-course the captive connector for the supply hose. Note the cross section of the supply. This is being replaced with a -8 line:-

image

 

image

I also removed the fuel filter mounting bracket, as I'm going to need to fasten the aeromotive filter that's replacing the stock filter somehow, so will need to fabricate some kind of bracket.

 

The keener eyed ones amongst you, would have noticed that I've not removed the catalytic convertor completely yet. This is because the temp probe's fixing bolts (Note, I don't think UK cars have this) were 9/10's of the way to being completely rounded off. I had to remove the temp probe anyway, so figured I'd disconnect the probe which goes into the cabin via a grommet in the floor, and remove the whole lot in one go.

image

image

 

To do this, first of all I removed the drivers foot rest:-

image

 

Then the kick panel and lower door trim:-

Then if you pull the carpet back from the front of the centre consol, you'll see this connector:-

image

image

 

If you disconnect this, and then follow the loom down to the floor, you'll find this grommet:-

image

 

If you push this grommet through the bottom of the floor using a screwdriver, you should then be able to pull the loom through, and then completely remove the catalytic convertor:-

image

Here you can see the grommet. I'll need to find a standard one of these to block the hole back up:-

WOHOOOO air filter has just arrived! Only took 5 weeks. :rolleyes: I'll post some pics up when I get home.

Seeing as I'm 6 weeks into the 8 week deadline I gave myself, and I'm still waiting for gaskets/flanges/resistor packs/dry break couplings, it looks like it's going to take me well into Autumn before it's finished, and I don't fancy much learning to drive a car with the kind of power this is going to be making during the Winter, so it looks like it's not going to be making much of a debut before next Spring. Gutted. :(

Parts all starting to roll in at last! Still waiting on Gaskets and Flanges though, although I shouldn't think they'll be long now.

 

Anyway here's the filter I bought, what's your thought's chaps?

image

 

And the last few parts for my fuel filter assembly came in today :nana:

 

image

 

No fuel leaking onto me when I have to strip it down and replace the filter :cool: :eyebrows: :-

image

image

 

I also stripped the stock fuel lines and test fitted the -8 feed and -6 return lines on my day off yesterday. I then had to strip them back out to make the lines up, which I did tonight at work. They're being pressure tested at just over twice their maximum working pressure (150psi) tomorrow morning. When I get 5 minutes I'll post up pics.
