Turbo troubles, hardly boosting

[rickye]

Fitted a k14 to my dturbo today, as the gt15 went

All went smoothly, new gasket and all, but it is very slow to boost, like well over 3k in 2nd before its hitting over 12psi

It has a mbc fitted, and turbo came off my last engine, which was took out just over a month ago, it boosted 100% when on that engine, and turn'd ok by hand

One thing I have noticed is it apears to be drawing a vacum, never seen any of my dturbo do it before

Anyone any idea's, I'm thinking something on the intake pipe, maybe its crused before it goes onto the turbo, but tbh I'm stumbed

What pipe have you got on the inlet of the turbo?

There's something probably restricting the inlet side.

[sweeney1987]

you plug back in boost compensator?

If your drawing a vacuum something is stopping air getting into the engine, Sounds like something to do with your inlet/air filter deal.

I just have the plastic pipe that runs along the back of the engine, no filter on it

I do still think its air, cos the turbo is whistling abit on tickover

Boost comp pipe is back on, forgot it the first time I took it down the road, have had a chance to get a look at it today yet

Cheers for the advice
