I am in the process of installing a custom turbo kit on my 98 GS 5-speed. I have the following mods: BIG 16G w/ 9psi wastegate actuator, EVO 3 o2, custom 3" downpipe, 3" Thermal catback, Hahn/Accel 310cc/min injectors, Walbro 255lph pump, Crane 0016 cams, Crane Hi-rev valve springs, Crane Ti retainers, AFX UDP, AEM cam gears, Greddy FMIC, VC1, overbore throttle body, ported intake manifold.

I want to make sure that the bottom end can handle all of this.

bottom end has nothing to worry about there but the 9psi.

what kind of horsepower am I looking to get with these mods??? Crankshaft and wheel?

hmm I'm hopping you meant 9lb spring 9psi is kind pushing it for daily driving. But you looking at around 200-300 HP. My guess....

Post pictures and stuff when you get it working, it's always interesting to see a cutom kit. Don't blow it up while your at it, hope you know what your doing :P

Be careful with the settings on those cam gears once you are turbo. normally stock cams are best for turbo.

Ahh..I ran 8.5-9psi for the past year never a prob....
I have now beefed up the bottom end a bit in hopes of hitting 15psi.or above soon

On the turbo he is using I think 9 psi should be fine. The big 16g is smaller than the super 16g right? And I run 8 psi on mine and have been for a while. 9 is kinda high but it will work.
