Thanks for the input! I will probably keep my BOV vented to atmosphere since I have not done the TB flip...

The only reason turboing these N/A motors seems to get a bad rap is cause guys go ahead and dont tune properly and/or get greedy with boost. These EJ22's are tough engines, the weak link with boost would def be the pistons in my opinion. Not because they are not forged, but because the have too high of compression for lots of boost on pump gas. The last turbo Honda I did made 280 whp, and used the stock DOHC ZC block with eagle rods and Suzuki Vitara pistons. Comp. ratio was low 7s, but I was able to run 27 psi of boost on pump gas... If I can get a set of EJ22T pistons, and the yellow top STi's injectors, I will go for broke on my EJ22 block... Or maybe I will mod my stock grey top injectors, they are just lying around. I dont want much over 400cc if I can help it. The other idea I had was to use the ej25 heads from a 98 legacy to bring down compression... I have access to these heads real cheap!
