Ohh..
Sorry that was the price for GT30 with Ext gate your right......
The GT25/30 im referring to is the garrett unit with gt30 comp wheel but with the .70 comp cover it hits the exhaust manifold apparantly.
In that case u will need Turbo, new manifold, New Dump pipe, new oil and water lines new inlet and outlet piping on Compressor..
So i just opted to keep the Standard exhaust housing with a t4 front end so all i had to change was the wastegate brackets and both inlet and outlet of the t4 compressor, havent started it yet hopefully finished tonight
