BTW, FMS makes the injectors I would need @ $600 set.. Ouch.. Maybe time to setup for pump fuel..
And if you have improper impedance it is likely you will "detonate" your engine/block.

Its pretty much the same thing as Ohms in a speaker. Injectors are solenoids which just take duty cycles in milliseconds.

Working on the EGR delete and ABS relocation. Lots of decisions to be made.

PCV is still up for debate... Either check valve and vent can.... or idk what else yet.

That's a good thing IMO , build a Mark 8 into the shroud and spend bucks on the painless F5.

I'll prolly make my own shroud out of fiberglass. Holding the two radiator fans. Prolly add a single one to the intercoooler.

E-fans are so damn expensive! I was thinking about getting some, but after seeing most are like 800$ or more I opted out.

I actually got a lightning fan shroud a few days ago from one of my buddies. It looks at least 2 inches more shallow. So you can fit a bit more inside, but you have to extend the shaft on the waterpump or change waterpump all together so the fan actually fits inside the shroud.

Another alternative is to use OEM e-fans from a 05+ silverado in conjunction with a flexalite variable speed controller. This guy with the setup says it costed him 175$ for evreything. I can post pictures if you want. Just don't want to clog up your thread. But it definitely saves some engine bay real-estate while keeping it simple and cheap.

Thanks for in info. I have a 4.5 quart radiator so efans shouldn't be an issue. I have a set here, so I'll throw them in sometime later. Pulling the intake now.

Efans will never be as reliable as stock and most can't pull as many cfm as stock.

If I didn't have a huge radiator I would be worried. I'm a fan of the stock setup. But it has to go to make room for the 4" intake

All parts you see are for sale. Injectors and all.
