my friend has a TD05 "big" 16g and it is a sweet little turbo. i welded the internal gate closed and welded a external gate to the manifold. he runs 28psi and makes almost 400whp. super quick spool and still makes power at 8k on a 2.0L.Sideways s12 wrote:I have a td05 16g on the wifes dsm and its a pretty good turbo it spools quick and has a nice power band the 18g is slightly larger so i would assume it would have the same properties in spool time and power band that the 16g does only difference is you'll be able to run higher boost numbers I believe the 16g maxes at 18psi as where the 18g is 22psi...
