Compressor tube no-no? More space in the engine bay :D

I don\'t need to any more! Although I will for MOT\'s, just so they\'re definitely properly aligned.

Thanks Timmy, LOTS of people had a gander on the way past, I wonder which one you were? :p

Indeed, they are too awesome to be bothered to move

[B.Martin]

Agree\'d! :Giggle

Back to topic. Anyone any idea\'s why I cannot get past 0.4 bar boost? This is only the stock level of boost, and so is pretty frustrating.

[the hat]

i know its rough but try removing the vacum hose that runs to the actuator and drive the boost should go mental if this doesnt happen you have a problem with your actuator or wastegate stuck open possibly

otherwise you have a big bad boost leak possibly but im sure you would have heard it

[papercutout]

Right, did this today. I know it\'s taken a while, but I\'m working stupid shifts etc atm.

Off came the pipe, and voila, boost! Well, upto 0.45/0.5 and boost cut or whatever the effing thing is doing again.

Does that mean that my MBC is only rated to reallllly low boost, and I need a stronger spring? (and that I probably need an FCD/different aftermarket ECU, as I guess the R-magic one is foobarred )

[m1tch]

Does it hold at 0.5bar? Have you checked for a split in the MAP sensor vac line? Also, where are you getting the vac from on the MBC?

[papercutout]

No, it burrrrrrs, like hitting a limiter. It won\'t CUT the fuel in a big cut, but it stops pulling and feels horrible. I don\'t want to do it much as I don\'t have an AFR gauge and it\'s probably damaging my engine.

See this page for how it\'s plumbed in: And which pipe in the MAP sensor vac line?)

MAP sensor is on the left hand side of the engine next to the air filter, it is a small black box with a plug and a hose going into it.

The clicking might be the OEM boost solinoid clicking away, the boost solinoids are known to go on the FDs but not on FCs that much, at what RPM does it stop pulling?

[papercutout]

It doesn\'t click. (where\'d you get that from?) The burrr is really odd, but definitely wrong.


I\'ll check the MAP sensor pipe in the morning.

RPM depends, it\'s as soon as it hits that level of boost - so generally 2700rpm or so, when it hits what should be full boost.

To fit the compression tube with TMIC, you need:
 
1) to cut the passenger side intercooler bracket - you have to cut about half of it off - I think Mitch has some piccies of what he did - probably also find some in my rebuild thread.
 
2) You\'ll need an ARC intercooler, HKS intercooler or a modified stock one with exit in the centre on the passenger side.
 
3) a 90 degree reducer - 76 to whatever you\'re intercooler needs.
 
Otherwise it will fit with Front or V-Mount intercoolers.

I know its unholy thread revival...  

But, i am hoping to get mine fitted this weekend i have a few questions before i get stuck in.

The first relates to the intercooler bracket that needs cutting, i don\'t remember seeing one on mine when i took my stock top mount off last week? Could you shed some more light on this?

The second is that if i remember correctly there are 2 small hoses on the top left corner of the stock cooler, what do i do with these as the ARC doesn\'t seem to have a connection for these hoses. (They are very small)

Finally, there is a hole on the front of my ARC, it has a thread in it. Apparently it is for a bracket that ARC originally sold with the intercooler, but i don\'t have one and apparently it was pointless anyway. I beleive it is 10mm wide, i am okay to just plug this with a 10mm bolt and a washer right? Anyone else got this on theirs?

Thanks :Thumbs-up

[m1tch]

Its not the intercooler bracket that needs cutting, its the engine hoist bracket, I have a photo somewhere I will post up

Im not sure where those go to on your setup but I know I have one on my ARC.

I have that on mine, plug it off, use it for water injection at a later date

[B.Martin]

Yeah if you can show me that pic please, also of anyone else can shed some light on the 2 hoses that connect (or don\'t in this case) to the top left of the intercooler.

[B.Martin]

Just to clarify its these 2 that you can see below that plug into the back of the stock IC, that I\'m not sure about? A thin and a thicker one.



This is we\'re the thicker one plumbs into.


Thanks
