Your crankshaft in your SX12 RE Turbo is most likely the 2146 cranskhaft which does not have a turbo scoop.
If you want to upgrade that, you can get the 2148 crankshaft which has the additional turbo scoop or the 2149 crankshaft which includes a turbo scoop PLUS the fact that it also has a bigger inlet
You can put and exchange out your 3 port sleeve to a 5 port one (2133). Should work straight out. However, if you look at the parts list of a 5 port Novamega engine, you will notice that they include the 5 port and the new 3 port RACE engines with the 2149 turbo crankshaft with the big inlet. I think the 5 port sleeve would be take advantage of the bigger inlet of the crankshaft.
