i was told the one closest to the firewall is the 1st turbo, and the 2nd one is on radiator side

hmm interesting.

thanks for the help but i've worked it out myself i think. looking in the engine bay, it appears as though my thoughts were correct, and the front turbo = first turbo.. i come to this conclusion based on the location of the vsv

any thoughts?

LOL so many people who don't know this?

The first turbo (the one that comes online first) is definitely the one on the radiator side Razz

I suggest some people go lookup how their sequential system works

just realised I boosted the wrong turbo... bugger! looks like back to the garage. what was with the "if you put your boost t in the front (radiator side) turbo line and blank off your vsv then you will only have high boost when both are online" crap? CONFLICTING INFO PPL!

...the front turbo is the first one
but the front turbo holds the wastegate, which controls boost when *both* are online.

to boost the first one without increasing total, u need to tap the EGBV, which hangs off the side of the second turbo. Razz

hahaha all good bro

The vaccum and VSV arrangement can be confusing, but it all makes sense in it's own weird kinda way

Just at first it looks wrong because the lines attached near the rear turbo control boost on the front turbo and visa-versa Razz
