Ok, so i am right now using stock bov and stock side mount IC. I am getting a T70 and new manifold though and i will be upgrading to a front mount. My question is if i use like a greddy BOV can i recirculate it? Because my car runs like **** now if i dont recirculate. Im sure others have had this problem so please inform me. thanks

you must use the routeback bov system on a sr but to make it blow off atmospherically it requires a piggy back or standalone. most maf cars use routeback

I have a HKS SSQV, un recirculated, and no aftermarket tune or computers. My car runs perfectly, doesn't stall, and idles like a dream.

way off topic but assassin, do you know if the 30mm callipers will fit in the stock wheels? and aslo, did your ebay fmic line up perfectly? and did u notice a slighlyly smaller peak boost #?

There are two different castings for stock 7 spoke S13 wheels. One type has larger webbing behind the spokes, and the other type does not. The 30mm will clear the one without enlarged webbbing, but will hit on the type that has enlarged webbing. In either case, it's nothing a small spacer won't help. The 30mm calipers and rotors will not increase your max brake force, but will increase your fade resistance. If you plan on tracking your car, get 30mm calipers. If your car will see street duty only, then get the 26mm calipers.

The eBay FMIC lines up well. There is some misalignment with the piping, but it's not bad enough to cause power loss. My wastegate is referenced from my intake manifold (throttle body vac line), so my boost stayed the same. However, if your wastegate is referenced from the IC piping (nipple on the IC tubing), you will see a pressure drop as the air becomes denser in an FMIC.

do you have a front mount or side mount? and on the turbo inlet pipe do you just have the recirculation port plugged?

i think enthalpy can adjust your tune so you don't need to recirculate. or at least, i have an enthalpy tune, and i run like **** if i recirculate.
