My car currently had just a catback exhaust and pods, with the boost restrictor removed.

I just had hks 2540's and dump pipes fitted, and ive got a pfc ready to be tuned but waiting on some cam gears to arrive first.

the car used to make 1bar with the factory turbos, now it only makes about .7/.8bar and takes a real long time to make boost (I know the 2540's are laggy but I think this is taking longer then it should)

I went down and bought a simple bleed valve hoping to get a harder boost curve (least come on boost quicker) and maybe raise it back to 1bar, is this a good idea?

Is there any chance of maxing out the injectors or running too rich at this stage at 1 bar with these turbos?

Anyway how do you install the bleed valve into these engines, my mechanic said it wouldnt work plumbing it into the hose that had the restrictor and talked about pluming it into a thin metal pipe on the turbo side as he said that would control both turbos

Is he right or is he making it seem harder then it really is to install this thing

Thanks in advance :headspin:

The factory hoses are very hard to get access to.

The easiest way to do it is to block all of the old hoses and run new hoses from the intake manifold through the bleed valve, to a tee junction and then to each wastegate actuator. This keeps the hoses nice and short too.

Yeah just get a crappy bleed valve for now, shit i cant even afford a boost controller yet and im running 1.2Bars on the GTS-T also with a GT-2540. Dont know what you mean by laggy, the mechanic when i had it on the dyno said it kiked in very early.

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
