I was just going piggyback off cheeky's question, as a lot of the information there pertains to this - so no need to double post that stuff - but I didn't want to have info for two different setups in the same thread, confusing people.
Starting from the inlet my set-up will be:
Evo MAS to Dejon Tool 1g 4" intake.
8-blade HX35 w/ BEP .55 a/r turbine housing
ETS intercooler system
stock TB
Cyclone IM
DSM Graveyard Frankenstein head or similar local build
8.5 CR
FP cast manifold
MAP or Punishment Recirculated external waste-gate/o2 housing
2.5" turbo back exhaust (considering building a 3" in the future. Car already has the 2.5")
The turbo seems to like to live at a 2.5-3.0 pressure ratio, so I'm thinking of running a dual stage setup with waste gate spring set at a 2.5 PR (about 22 psig) and being able to bump it to 3.0 (about 30 psig) with a solenoid and mbc.
Of course I'll have all the necessary fuel mods for this. Walboro 255HP, 850 cc injectors, and Aeromotive fpr.
My power goal is 350-400 whp which IIRC I should meet at about 25 psi, if my assumptions are close. But if I do go for the two-stage setup I'll be able to have a good "around town" setting, and then get it on a dyno to max out the setup.
I'm looking for quick spool up, and a broad power band. This will be a weekend warrior and auto/rally cross car.
I'm tempted to see what I can do with stock cams, but at the same time I'm fairly sure they will choke me off at higher RPM's, and I'd rather not have to pay for more dyno time than I need.
I'm sure I don't want/need more than a 272 duration cam, and am questioning if even that might be more than I want. I've been looking hard at the fp1x which seems to be a little more aggressive than a 264, with higher lift. I've also been thinking about something like a 272 intake/264 exhaust (opposite of the standard 264/272) to maximize intake potential, but still keep exhaust gas velocity up for optimized spool.
I've got some time before I need to make this decision, but looking for some input to help clear things up.
