Lets talk turbos
Hey guys I hava a 99 si with a greddy 18g turbo kit. Its been on the car since 02 and the turbo has devoloped a fare amount of shaft play. Instead of rebuilding it I am wanting to upgrade it. I kept the 16a2 and virtually the same displacment. I am wanting to run 18-20 psi. I dont have a problem with switching over to t3 or t4 flange and running an external wastegate. Any suggestions on a turbo? If so where to find it?

As of now the head is stock Ill be building it soon. The block was built by ERL Performance. JE 9.5:1 pistons, Eagle H beam rods, blue printed and balanced, type r oil pump, type r water pump. Its tuned with hondata at 12psi

if you want to just replace that one you can get an evoIII 16g basically a 18g or might even be bigger. or get a hahn craft super 16g with i think 10cm2 housing instead of the regular 7cm2 housing and the super 20g for more power
sorry i only know about mitsubishi turbos lol

the evoIII will spool pretty fast still, just not as fast as the small and big 16g, you can look into the evo 8 MR turbo (i got one) its a twin scroll for a faster spool. i belive it has the same wheel as the evo 3(not sure thou) but it has a 10.5cm2 i belive. its not the same flange thou, it has the evo flange. you might be able to use the manifold off the evo 8 on your b1 thou
