Storm Modifications - RS Engine Swap

Isuzu Impulse RS Engine
Isuzu Impulse RS turbo intercooler

I got the engine in and everything is running smoothly. I still have a couple of bugs to work out, and many boost leaks to plug. I am currently running 10-14psi boost, and sometimes it spiked to 15-20psi and fuel cut is initiated. I need to install a FCD soon. Sofar, I have not seen any issues or running lean with the Tbird turbo and the higher boost.
1.8L GSi Cam Swap
Geo Storm GSi 1.8L cam swap
I installed the 1.8L GSi Cams. Was an easy swap-well it was real easy with the engine out of the car, only took 15 minutes.
UPDATE: I swapped out the 1.8L GSi cams and the RS solid lifters and installed the IMARK cams and hydraulic lifters. The engine is a lot quieter now, but I am a little dissapointed in the performance at this point.

Here is all the information I have on Isuzu Camshafts:

Understanding cam specs and their affects will help you select the best cam for your specific engine. The four important camshaft specs to understand are duration, lift, centerline, and separation.

Lift Duration
Duration refers to how long a valve is opened in relation to crankshaft rotation. This open valve time period is expressed in degrees of crankshaft rotation. So, a cam specification of 244 degrees duration simply means the cam holds the valve open for 244 degrees of crankshaft rotation. As a gene
