gtr turbo match porting

[fatz]

Just recently rebuilt my gtr motor

The car when on standard boost would generally run .75-.8 bar boost

When the turbos were off I notice that the manifold to turbo and the turbo housing and the gaskets were out of wack eg probably 30% area is blocked off... apparently all mechanics know this but i didnt

So out with the grinder and nath managed to properly match the manifold to turbo connection (cost nothing)... its much smother for both the turbo housing and the manifold and I would say the area of the connection is easily 30% large

Now the change

Everything is back in and suddenly standard boost has jumped to 0.95 bar and I cant get anything lower don’t know about top end cause I cant rev her past 5k until its run in but there is a noticeable improvement... however id imagine the smother path woiuld make it flow easier.. thus more power

So get it done people easy free horsepower
