So basically a good catch can setup and a modified pipe. Hmm well I'll start looking. A stock short block seems fairly inexpensive. The tranny will be the biggest cost. At least with the sti block the 6MT will bolt up with all 8 bolts not 4 lol.
So the oil and coolant journals are the same between the 2.5 block and the older phase 1 ej20g's?
