Electronic all the way
Gizzmo MS-IBC is what I run and I love it. Swap the springs and put the 14psi spring in there, it's only 1 psi but worth it. By the way they are real fun to change by yourself so you might want someone to help you...
If you got the same turbo as me you will need to make a little room for it. Grind the block casting a little and the bottom left motor mount bolt head needs to be cut down a little for perfect fitment. The block grind does not remove any material that is important as you will find when you do it. It's just an area were the casting is very thick and hits the exhaust housing on the turbo.
Remember to make sure you get the correct down pipe bolt flange so you don't have to get changed like I did. The OBX manifold comes with the down pipe in the kit, that flange needs to be a standard 4 bolt turbo exhaust flange on that down pipe Also if you figure out how to install the waste gate dump pipe I want pictures since I was unable to get one on mine without firewall fabrication (too lazy to do it). My waste gate dumps right out the waste gate dump toward the back of the transmission....No worries since it doesn't dump much or for too long. 1,500 miles and no exhaust marks or burns anywhere from the dump...
I think I'm going to have to go to church tomorrow
with the camera mounted inside so I can show you what 14.7psi is like. Remember my car is low compression so yours at the same boost will be a little more powerful. I'm sure you will have problems sleeping a night until your project is completed after you see this video
