I know you got your 300+hp turbo tibby project going on, and im sure you probably already answered this question over at FX, but what kinda turbo you plan on getting and how much boost do you plan on running??? im dieing for you to get this thing finished.<img src=icon_smile.gif border=0 align=middle>thanks man.<img src=icon_smile_clown.gif border=0 align=middle>
Heya guys, sorry I didn't see your replies! Duh me...
Clown: I haven't decided on a turbo yet. I think I'm going to continue with my original plan and continue with the IHI RHB5 VF11 that I have now... It's good for almost 400cfm at 15psi, which means I'll probably be only to keep about 9-10psi in the car without maxxing out the poor little turbo. That's likely enough for 230HP, which is just fine for breaking in the new motor.
Once the rings have settled and I have the tuning nailed down, I'll swap out for an ISHI RHB7 VF30. This turbo is a direct replacement for the RHB5 VF11, as the bolt patterns for the up-pipe and down-pipe are identical.
However, the VF30 is good for like 635cfm at 15psi, but the turbo itself can spool beyond 30psi while still sitting in the 70th-percentile efficiency range. It can actually flow 900+cfm at this level, which means it's good for 350HP (and well beyond) at the tires. Spool times on this turbo are also still very good; positive pressure begins at 2800 RPM's on a Subaru WRX, and full 1 bar hits at 3400 RPM's on the same motor.
The VF30 also costs $1800 brand new, so it's not a cheap expenditure. Full ceramic ball bearing cartridge, 16cm^2 turbines, and enough flow to make anyone sick. It's worth the 2G's for the amount of sickening boost it can spew.
As for Endyn, I believe they're specifically doing forced induction pistons only. For supreme N/A pistons, you'll have to go with HVE or RPW. <img src=icon_smile_dissapprove.gif border=0 align=middle>
