I'm in the process of working out my FMIC setup and ran in to a few Qs that I'm hoping some of you turbo folks can help with.
-IC core size. I've found a bar & plate design that I like, core size is 21 x 5.5 x 2.5. Seem big enough?
-Would 2" IC piping be too small? The m106 turbo outlet is 2", as is the intake tube. Plus I have a lot of 2" pipe and couplers already. I'd like to reuse what I can, but am I shooting myself in the foot with small-ish pipes?
-BOV size. Is a 25mm port BOV large enough for an engine/pipe setup like this?
- Manifold vacuum source(s). I need at least 3 "signals" for the MAP sensor, boost controller, and boost gauge. m20s have that nice little plate on the manifold, but no such luck on m30s. Where did you guys go for your vacuum signal? Drill+tap the manifold, or use one of the existing ports for the FPR or brake booster and tee off?
- Does the IAT sensor on an MS2 setup go before or after the turbo?
- SInce the m30 has the intake/exhaust on the same side of the engine, piping is a little wonky. I found this OEM Saab designed IC that actually fits the bill nicely, but it's small and would have limited capacity: http://www.ebay.com/itm/151854256470...%3AMEBIDX%3AIT. There's an aftermarket version made in Sweden that has a much larger core and more capacity: http://shop.klracing.se/sv/artiklar/...crossflow.html. But I'm unsure about the same-side inlet/outlet design as far as flow/efficiency goes. Any input?
