looks good - I enjoyed looking at the album! What level of boost are you planing on (for the garrett)?

I'm limited by the size of injectors and strength of the gearbox, so I guess no more than 1.5 bar at least for a while

?

I had to do the turbo downpipe, water and oil lines etc, and it's much easier with the bumper and radiator removed

Any ideas where to buy a new knock sensor. The two sensors I have are both badly damaged ( the rubber insulation + very bad cables) and I really don't want to get another used one

is that the same one as in q4 ?

It's looks equal, but can't be sure if it's the same.

Shouldn't be the same as Cosworth uses almost the same ECU (IAW P8)??

I was wondering what are your plans on the oil cooler and air passage to it with this front bumper, or are going to change the location of the oil cooler/radiator.
Thanks

it stays on the default location, no probs at all.

Air will be sent to it from the hallo whole (haven't drilled it yed, still looking for appropriate part for it, maybe the edges from some old broken hallos)

Did some tests on the rear brakes today. Old front discs with evolution calipers ... not exactly bolt-on but not so dificult at all, hopefully will be done next weekend

Well I bought it ... it's not the same, different thread :)

Doable however, will make it 8x1.25 (no it is typical ford - 10x1.5)

I had the exact same question Jack :biggrin:
My guess, a fuel presure regulator with "connecting kit" for custom plumbing?

Oh, and I forgot the presure gauge ;)
But would this be a adjustable regulator :confused:

yes, I saw them today, completely forgot about these. Any ideas where to buy just them ???

Hi, Jivco.
How did you managed with the two extra brake hoses?

I have also received a 4 hoses kit and the local dealer sais that these are the Goodridge specifications for the 155Q4. I have sent them the chassis number too before ordering.

After I have compared with the OEM brake hoses, it doesn't seem to me having same sizes at all. Neither the same configuration.

My curiousity is why Goodridge have same specifications for 155Q4 as for others 155... http://www.goodridge.co.uk/car-brake-lines/alfa-romeo.htm

Yes, they are not for q4, and need some invasions :). The short ones ... I've ordered them here in Bulgaria in a workshop, custom built.

I did not contact Goodrich, so if you got the patience, maybe you should.

there is a set with 4 brake hoses and one with six, you just need the one with six

Thanks, Jivco.

Jan, do you have by chance some picture with the 6 hoses kit.
? I'm thinking to show it to my local dealer too. Thanks in advance.

Cheers,
Cristian.

This comes up now and again on alfa155.org. Have a look here for an idea of 6 hose set part numbers:

I forgot to mention something, that may be will help somebody some other time - I switched to ford ignition coil, after a friend recommended it to me, and it solved a lot of ignition problems.

Every ignition coil from ford - from fiesta up to focus wrc are all the same in case you're wondering which one do you need ;)

Hi all,

I'm willing to sell my q4.

It's been a while since it last ran, and I don't see any chance to drive it soon ( too busy working etc. )

Drop me a line if you're interested, so I could give more details about the state of the project
