Hello,

 

I am looking for the measurements (couplers and silicone hose) for the lower turbo boost connector pipe, photo attached.

 

Does anyone know what size of hose and couplers I would need to buy if I'd want to rebuild it from scratch?

I know there are hard pipe kits, but I am planning to buy an FMIC upgrade in 2-3 months so only need a temporary solution and the OEM pricing is pretty steep.

 

TIA

 

 

Hi mate I’ve recently had the same problem after changing my turbo, bottom boost pipe was blowing out of the intercooler and there was a hole in the silicone turbo outlet pipe. Same as you thought the crappy oem ones were too pricey so I decided to make up new bottom boost pipe with silicone hoses and a piece of hard pipe all bought off eBay it probably cost me about £80 to do. Even after I changed the bottom pipework the new coupler still kept blowing out of the side mount intercooler because it was either damaged where the coupler went into it or blocked and causing a back pressure, so I just bit the bullet and ripped the lot out got a FMIC and hard pipework so it was a bit of a waste really.   

 

Fortunately when I decided to go for the FMIC and hard pipework I still managed to use the turbo outlet hose and coupler I bought.

 

heres the parts I got to replace the standard oem bottom boost pipes from turbo outlet to intercooler. 

 

That’s the outlet hose I used with the couplers.

That should join up with the standard pipework but I didn’t check as I made up complete new bottom pipe. Using this 51mm o.d 90degree :

it required cutting down to the correct length then a bead putting back on the end there’s a how to on YouTube for the bead. 

 

I then used another 90 degree silicone elbow 51mm I.D.  :

Then the coupler that went into the intercooler was a 60mm-51mm

I used jubilee clips to hold it together I know people recommended mikalor clamps but due to previous experience with these I tend to just stick with good quality jubilee clips. 

 

 

 

There’s a picture of it on the car:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Sorry mate just noticed yours has the BLT engine probably has the Garrett turbo on mines the ASZ with a KKK so I’m guessing the outlet pipe maybe different.

Thanks for the detailed post and links. The BLT ones have the same KKK BV39 turbo btw, the only difference is smaller injectors (530 cc) and different EGR and ASV.

 

The FMIC and hardpipe kits are the same, only EGR delete should be different cause of EGR cooler pipe.

No problem, I had a lot of messing about to get it right and found most of the information I needed on here so it’s only fair to help others out!

 

Yeah I knew about the Different EGR

wasn’t sure about the turbo I’ve seen some ASZ engines come with a Garret standard but thought it was mainly the BLT engines with them so maybe it’s just pot luck 

 

i found fitting the hard pipework for my fmic a bit of a pain. Although the quality of them was good the welds etc one of the bends wasn’t enough so I cut it and re welded it for a better fit. I think the hard pipes I got were 57mm O.D. So to fit them into the turbo outlet hose I previously bought I chopped the end off and turned a reducing piece that was tapered on the inside and welded it in worked a treat.

 

if you decide to go for a hard pipe kit try and make sure that all the sizes match up when you order to avoid the ball ache I had. I’m lucky I can do the work myself others might not be so lucky!

 

Here’s the pipe I welded a piece in to to reduce the size: 

 

And the hard pipes on the car.
